BASIS OF PRESENTATION	6 Months Ended

Basis of Presentation [Abstract]
Basis of Presentation	BASIS OF PRESENTATION Basis of Presentation The unaudited interim Consolidated Financial Statements, including the Notes thereto of Citizens Financial Group, Inc., have been prepared in accordance with GAAP interim reporting requirements, and therefore do not include all information and Notes included in the audited Consolidated Financial Statements in conformity with GAAP. These unaudited interim Consolidated Financial Statements and Notes thereto should be read in conjunction with the Company’s audited Consolidated Financial Statements and accompanying Notes included in the Company’s Form 10-K for the year ended December 31, 2014 . The Company is an indirect subsidiary of The Royal Bank of Scotland Group plc. The Company’s principal business activity is banking, conducted through its subsidiaries, Citizens Bank, N.A. and Citizens Bank of Pennsylvania. The unaudited interim Consolidated Financial Statements include all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of the results for the interim periods. The results for interim periods are not necessarily indicative of results for a full year. On August 22, 2014, the Company’s Board of Directors declared a 165,582 -for-1 stock split. Except for the amount of authorized shares and par value, all references to share and per share amounts in the unaudited interim Consolidated Financial Statements and accompanying Notes have been restated to reflect the stock split. Certain prior period amounts have been reclassified to conform to current period presentation. These reclassifications had no effect on net income, total comprehensive income, total assets or total stockholders’ equity as previously reported. Recent Accounting Pronouncements In April 2015, the FASB issued ASU No. 2015-05 “Intangibles - Goodwill and Other - Internal Use Software” which will assist entities in evaluating the accounting for fees paid by a customer in a cloud computing arrangement. The ASU, which allows for early adoption, is effective for the Company beginning on January 1, 2016. Adoption of this guidance is not expected to have a material impact on the Company’s unaudited interim Consolidated Financial Statements. In April 2015, the FASB issued ASU No. 2015-03 “Interest - Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs”. This standard requires debt issuance costs to be presented in the consolidated balance sheet as a direct deduction from the carrying value of the associated debt liability, consistent with the presentation of a debt discount. The ASU, which allows for early adoption, is effective for the Company beginning on January 1, 2016. Adoption of this guidance is not expected to have a material impact on the Company’s unaudited interim Consolidated Financial Statements. In February 2015, the FASB issued ASU No. 2015-02 “Consolidation (Topic 810): Amendments to the Consolidation Analysis”. This standard focuses on the consolidation evaluation for reporting organizations that are required to evaluate whether they should consolidate certain legal entities such as limited partnerships, limited liability corporations, and securitization structures (e.g., collateralized debt obligations, collateralized loan obligations, and mortgage-backed security transactions). This new standard simplifies consolidation accounting by reducing the number of consolidation models. The ASU will be effective for the Company beginning on January 1, 2016. Early adoption is permitted, including adoption in an interim period. The potential impact the adoption of this guidance will have to the Company’s unaudited interim Consolidated Financial Statements is under review. In January 2015, the FASB issued ASU No. 2015-01 “Income Statement: Extraordinary and Unusual Items.” This ASU eliminates from GAAP the concept of extraordinary items. Accounting Standards Codification Subtopic 225-20 required that an entity separately classify, present, and disclose extraordinary events and transactions that were unusual in nature and infrequent in occurrence. This ASU, which allows for early adoption, is effective for the Company beginning on January 1, 2016. The adoption of this guidance is not expected to have a material impact on the Company’s unaudited interim Consolidated Financial Statements.

If the Company has determined that the present value of the debt security’s expected cash flows is less than its amortized cost basis, an other-than-temporary impairment is deemed to have occurred. The amount of impairment loss that is recognized in current period earnings is dependent on the Company’s intent to sell (or not sell) the debt security. If the Company intends to sell the impaired debt security, the impairment loss recognized in current period earnings equals the difference between the debt security’s fair value and its amortized cost. If the Company does not intend to sell the impaired debt security, and it is not likely that the Company will be required to sell the impaired security, the credit-related impairment loss is recognized in current period earnings and equals the difference between the amortized cost of the debt security and the present value of the expected cash flows that have currently been projected. In addition to these cash flow projections, several other characteristics of each debt security are reviewed when determining whether a credit loss exists and the period over which the debt security is expected to recover. These characteristics include: (1) the type of investment, (2) various market factors affecting the fair value of the security (e.g., interest rates, spread levels, liquidity in the sector, etc.), (3) the length and severity of impairment, and (4) the public credit rating of the instrument. The Company estimates the portion of loss attributable to credit using a cash flow model. The inputs to this model include prepayment, default and loss severity assumptions that are based on industry research and observed data. The loss projections generated by the model are reviewed on a quarterly basis by a cross-functional governance committee. This governance committee determines whether security impairments are other-than-temporary based on this review. The following table presents the cumulative credit related losses recognized in earnings on debt securities held by the Company: Three Months Ended June 30, Six Months Ended June 30, (in millions) 2015 2014 2015 2014 Cumulative balance at beginning of period $62 $59 $62 $56 Credit impairments recognized in earnings on securities that have been previously impaired 2 2 3 6 Reductions due to increases in cash flow expectations on impaired securities (2 ) (1 ) (3 ) (2 ) Cumulative balance at end of period $62 $60 $62 $60 Cumulative credit losses recognized in earnings for impaired AFS debt securities held as of June 30, 2015 and 2014 were $62 million and $60 million , respectively. There were no credit losses recognized in earnings for the Company’s HTM portfolio as of June 30, 2015 and 2014 . For the three months ended June 30, 2015 and 2014 , the Company recognized credit related other-than-temporary impairment losses in earnings of $2 million related to non-agency MBS in the AFS portfolio. For the six months ended June 30, 2015 and 2014 , the Company recognized credit related other-than-temporary impairment losses in earnings of $3 million and $6 million , respectively. There were no credit impaired debt securities sold during the three or six months ended June 30, 2015 and 2014 , respectively. Reductions in credit losses due to increases in cash flow expectations were $2 million and $1 million for the three months ended June 30, 2015 and 2014 , respectively, and $3 million and $2 million for the six months ended June 30, 2015 and 2014 , respectively, and were presented in interest income from investment securities on the Consolidated Statements of Operations. The Company does not currently have the intent to sell these debt securities, and it is not likely that the Company will be required to sell these debt securities prior to the recovery of their amortized cost bases. The Company has determined that credit losses are not expected to be incurred on the remaining agency and non-agency MBS identified with unrealized losses as of the current reporting date. The unrealized losses on these debt securities reflect the reduced liquidity in the MBS market and the increased risk spreads due to the uncertainty of the U.S. macroeconomic environment. Therefore, the Company has determined that these debt securities are not other-than-temporarily impaired because the Company does not currently have the intent to sell these debt securities, and it is not likely that the Company will be required to sell these debt securities prior to the recovery of their amortized cost bases. Any subsequent increases in the valuation of impaired debt securities do not impact their recorded cost bases. As of June 30, 2015 and 2014 , $29 million and $33 million , respectively, of pre-tax non-credit related losses were deferred in OCI. The amortized cost and fair value of debt securities at June 30, 2015 by contractual maturity are shown below. Expected maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations with or without incurring penalties.

The Company regularly enters into security repurchase agreements with unrelated counterparties. Repurchase agreements are financial transactions that involve the transfer of a security from one party to another and a subsequent transfer of the same (or “substantially the same”) security back to the original party. The Company’s repurchase agreements are typically short-term transactions, but they may be extended to longer terms to maturity. Such transactions are accounted for as secured borrowed funds on the Company’s financial statements. When permitted by GAAP, the Company offsets the short-term receivables associated with its reverse repurchase agreements with the short-term payables associated with its repurchase agreements. The effects of this offsetting on the Consolidated Balance Sheets are presented in the following table: June 30, 2015 December 31, 2014 (in millions) Gross Assets (Liabilities) Gross Assets (Liabilities) Offset Net Amounts of Assets (Liabilities) Gross Assets (Liabilities) Gross Assets (Liabilities) Offset Net Amounts of Assets (Liabilities) Securities sold under agreements to repurchase ($3,050 ) $— ($3,050 ) ($2,600 ) $— ($2,600 ) Note: The Company also offsets certain derivative assets and derivative liabilities on the Consolidated Balance Sheets. For further information see Note 12 “Derivatives.” Securities under the agreements to repurchase or resell are accounted for as secured borrowings. The following table presents the Company's related activity, by collateral type and remaining contractual maturity, at June 30, 2015 : Remaining Contractual Maturity of the Agreements (in millions) Overnight and Continuous Up to 30 Days 30-90 Days Greater Than 90 Days Total Securities sold under agreements to repurchase Mortgage-backed securities - Agency $— $250 $1,000 $1,800 $3,050 For these securities sold under the agreements to repurchase, the Company would be obligated to provide additional collateral in the event of a significant decline in fair value of the collateral pledged. The Company manages the risk by monitoring the liquidity and credit quality of the collateral, as well as the maturity profile of the transactions.

Receivables [Abstract]
ALLOWANCE FOR CREDIT LOSSES, NONPERFORMING ASSETS, AND CONCENTRATIONS OF CREDIT RISK	ALLOWANCE FOR CREDIT LOSSES, NONPERFORMING ASSETS, AND CONCENTRATIONS OF CREDIT RISK The allowance for credit losses consists of the ALLL and the reserve for unfunded commitments. It is increased through a provision for credit losses that is charged to earnings, based on the Company’s quarterly evaluation of the loan portfolio, and is reduced by net charge-offs and the ALLL associated with sold loans. See Note 1 “Significant Accounting Policies” to the Company’s audited Consolidated Financial Statements in the Annual Report on Form 10-K for the year ended December 31, 2014, for a detailed discussion of ALLL reserve methodologies and estimation techniques. On a quarterly basis, the Company reviews and refines its estimate of the allowance for credit losses, taking into consideration changes in portfolio size and composition, historical loss experience, internal risk ratings, current economic conditions, industry performance trends and other pertinent information. There were no material changes in assumptions or estimation techniques compared with prior periods that impacted the determination of the current period’s ALLL and the reserve for unfunded lending commitments. The following is a summary of changes in the allowance for credit losses: Six Months Ended June 30, 2015 (in millions) Commercial Retail Total Allowance for loan and lease losses as of January 1, 2015 $544 $651 $1,195 Charge-offs (21 ) (215 ) (236 ) Recoveries 36 68 104 Net (charge-offs) recoveries 15 (147 ) (132 ) Sales/Other — (2 ) (2 ) Provision charged to income 6 134 140 Allowance for loan and lease losses as of June 30, 2015 565 636 1,201 Reserve for unfunded lending commitments as of January 1, 2015 61 — 61 Credit for unfunded lending commitments (5 ) — (5 ) Reserve for unfunded lending commitments as of June 30, 2015 56 — 56 Total allowance for credit losses as of June 30, 2015 $621 $636 $1,257 Six Months Ended June 30, 2014 (in millions) Commercial Retail Total Allowance for loan and lease losses as of January 1, 2014 $498 $723 $1,221 Charge-offs (14 ) (231 ) (245 ) Recoveries 35 55 90 Net (charge-offs) recoveries 21 (176 ) (155 ) Provision charged to income (11 ) 155 144 Allowance for loan and lease losses as of June 30, 2014 508 702 1,210 Reserve for unfunded lending commitments as of January 1, 2014 39 — 39 Credit for unfunded lending commitments 26 — 26 Reserve for unfunded lending commitments as of June 30, 2014 65 — 65 Total allowance for credit losses as of June 30, 2014 $573 $702 $1,275 The recorded investment in loans and leases based on the Company’s evaluation methodology is as follows: June 30, 2015 December 31, 2014 (in millions) Commercial Retail Total Commercial Retail Total Individually evaluated $156 $1,189 $1,345 $205 $1,208 $1,413 Formula-based evaluation 44,912 50,281 95,193 43,021 48,976 91,997 Total $45,068 $51,470 $96,538 $43,226 $50,184 $93,410 The following is a summary of the allowance for credit losses by evaluation method: June 30, 2015 December 31, 2014 (in millions) Commercial Retail Total Commercial Retail Total Individually evaluated $21 $107 $128 $20 $109 $129 Formula-based evaluation 600 529 1,129 585 542 1,127 Allowance for credit losses $621 $636 $1,257 $605 $651 $1,256 For commercial loans and leases, the Company utilizes regulatory classification ratings to monitor credit quality. Loans with a “pass” rating are those that the Company believes will be fully repaid in accordance with the contractual loan terms. Commercial loans and leases that are “criticized” are those that have some weakness that indicates an increased probability of future loss. For retail loans, the Company primarily uses the loan’s payment and delinquency status to monitor credit quality. The further a loan is past due, the greater the likelihood of future credit loss. These credit quality indicators for both commercial and retail loans are continually updated and monitored. The recorded investment in classes of commercial loans and leases based on regulatory classification ratings is as follows: June 30, 2015 Criticized (in millions) Pass Special Mention Substandard Doubtful Total Commercial $31,443 $865 $635 $84 $33,027 Commercial real estate 7,949 133 34 41 8,157 Leases 3,831 4 49 — 3,884 Total $43,223 $1,002 $718 $125 $45,068 December 31, 2014 Criticized (in millions) Pass Special Mention Substandard Doubtful Total Commercial $30,022 $876 $427 $106 $31,431 Commercial real estate 7,354 329 61 65 7,809 Leases 3,924 12 50 — 3,986 Total $41,300 $1,217 $538 $171 $43,226 The recorded investment in classes of retail loans, categorized by delinquency status is as follows: June 30, 2015 (in millions) Current 1-29 Days Past Due 30-89 Days Past Due 90 Days or More Past Due Total Residential mortgages $11,853 $89 $65 $246 $12,253 Home equity loans 2,652 187 48 135 3,022 Home equity lines of credit 14,253 406 73 185 14,917 Home equity loans serviced by others (1) 1,027 58 20 21 1,126 Home equity lines of credit serviced by others (1) 390 61 22 21 494 Automobile 12,817 784 104 22 13,727 Student 3,209 87 24 35 3,355 Credit cards 1,542 39 18 14 1,613 Other retail 889 57 14 3 963 Total $48,632 $1,768 $388 $682 $51,470 (1) The Company’s SBO portfolio consists of purchased home equity loans and lines that were originally serviced by others.

Troubled Debt Restructurings A loan modification is identified as a TDR when the Company or a bankruptcy court grants the borrower a concession the Company would not otherwise make in response to the borrower’s financial difficulties. TDRs typically result from the Company’s loss mitigation efforts and are undertaken in order to improve the likelihood of recovery and continuity of the relationship. The Company’s loan modifications are handled on a case-by-case basis and are negotiated to achieve mutually agreeable terms that maximize loan collectability and meet the borrower’s financial needs. Concessions granted in TDRs for all classes of loans may include lowering the interest rate, forgiving a portion of principal, extending the loan term, lowering scheduled payments for a specified period of time, principal forbearance, or capitalizing past due amounts. A rate increase can be a concession if the increased rate is lower than a market rate for debt with risk similar to that of the restructured loan. TDRs for commercial loans and leases may also involve creating a multiple note structure, accepting non-cash assets, accepting an equity interest, or receiving a performance-based fee. In some cases, a TDR may involve multiple concessions. The financial effects of TDRs for all loan classes may include lower income (either due to a lower interest rate or a delay in the timing of cash flows), larger loan loss provisions, and accelerated charge-offs if the modification renders the loan collateral-dependent. In some cases, interest income throughout the term of the loan may increase if, for example, the loan is extended or the interest rate is increased as a result of the restructuring. Because TDRs are impaired loans, the Company measures impairment by comparing the present value of expected future cash flows, or when appropriate, the fair value of collateral, to the loan’s recorded investment. Any excess of recorded investment over the present value of expected future cash flows or collateral value is recognized by creating a valuation allowance or increasing an existing valuation allowance. Any portion of the loan’s recorded investment the Company does not expect to collect as a result of the modification is charged off at the time of modification. Commercial TDRs were $124 million and $176 million on June 30, 2015 and December 31, 2014 , respectively. Retail TDRs totaled $1.2 billion on June 30, 2015 and December 31, 2014 . Commitments to lend additional funds to debtors owing receivables which were TDRs were $18 million and $53 million on June 30, 2015 and December 31, 2014 , respectively. The following table summarizes how loans were modified during the three months ended June 30, 2015 , the charge-offs related to the modifications, and the impact on the ALLL.

The table below summarizes TDRs that defaulted during the three months ended June 30, 2015 and 2014 within 12 months of their modification date. For purposes of this table, a payment default is defined as being past due 90 days or more under the modified terms. Amounts represent the loan’s recorded investment at the time of payment default. Loan data includes loans meeting the criteria that were paid off in full, charged off, or sold prior to June 30, 2015 and 2014 . If a TDR of any loan type becomes 90 days past due after being modified, the loan is written down to the fair value of collateral less cost to sell. The amount written off is charged to the ALLL.

Concentrations of Credit Risk Most of the Company’s business activity is with customers located in the New England, Mid-Atlantic and Midwest regions. Generally, loans are collateralized by assets including real estate, inventory, accounts receivable, other personal property and investment securities. As of June 30, 2015 and December 31, 2014 , the Company had a significant amount of loans collateralized by residential and commercial real estate. There are no significant concentrations within the commercial loan or retail loan portfolios. Exposure to credit losses arising from lending transactions may fluctuate with fair values of collateral supporting loans, which may not perform according to contractual agreements. The Company’s policy is to collateralize loans to the extent necessary; however, unsecured loans are also granted on the basis of the financial strength of the applicant and the facts surrounding the transaction. Certain loan products, including residential mortgages, home equity loans and lines of credit, and credit cards, have contractual features that may increase credit exposure to the Company in the event of an increase in interest rates or a decline in housing values. These products include loans that exceed 90% of the value of the underlying collateral (high LTV loans), interest-only and negative amortization residential mortgages, and loans with low introductory rates. Certain loans have more than one of these characteristics. The following table presents balances of loans with these characteristics: June 30, 2015 (in millions) Residential Mortgages Home Equity Loans and Lines of Credit Home Equity Products serviced by others Credit Cards Total High loan-to-value $748 $1,400 $974 $— $3,122 Interest only/negative amortization 961 — — — 961 Low introductory rate — 1 — 90 91 Multiple characteristics and other 20 — — — 20 Total $1,729 $1,401 $974 $90 $4,194 December 31, 2014 (in millions) Residential Mortgages Home Equity Loans and Lines of Credit Home Equity Products serviced by others Credit Cards Total High loan-to-value $773 $1,743 $1,025 $— $3,541 Interest only/negative amortization 894 — — — 894 Low introductory rate — — — 98 98 Multiple characteristics and other 24 — — — 24 Total $1,691 $1,743 $1,025 $98 $4,557

Variable Interest Entities [Abstract]
VARIABLE INTEREST ENTITIES	VARIABLE INTEREST ENTITIES Low Income Housing Tax Credit Partnerships The Company makes equity investments in various limited partnerships that sponsor affordable housing projects utilizing the LIHTC pursuant to Section 42 of the Internal Revenue Code. The purpose of these investments is to assist in achieving goals of the Community Reinvestment Act and to earn an adequate return of capital. Each LIHTC partnership is managed by a general partner who exercises full and exclusive control over the affairs of the limited partnership, including: selecting and investing in specific properties, company expenditures and use of working capital funds, borrowing funds, disposition of fund property, contract authority, employment of agents, and litigation resolution. The limited partner(s) may not participate in the management, control, conduct or operation of the limited partnership’s business and the general partner may only be removed by the limited partner(s) if the general partner fails to comply with the terms of the partnership agreement or is negligent in performing its duties. In addition, Citizens, as a limited partner, is only liable for capital contributions up to a maximum amount specified in the investment agreement. For all of these reasons, the Company believes that the general partner of each limited partnership has the power to direct the activities which most significantly affect the performance of each partnership and that the Company is therefore not the primary beneficiary of any LIHTC partnership. Accordingly, the Company does not consolidate any of its LIHTC partnership investments. Effective January 1, 2015, the Company adopted ASU 2014-01, “Accounting for Investments in Qualified Affordable Housing Projects” and uses the proportional amortization method to account for all of its investments in its LIHTC partnership investments. The retrospective adoption of ASU 2014-01 would have had an immaterial effect on the Company’s financial statements; therefore, the Company applied ASU 2014-01 prospectively. Under the proportional amortization method, the Company recognizes the net investment performance in the Consolidated Statements of Operations as a component of income tax expense. LIHTC investment balances are reported in other assets in the Company’s Consolidated Balance Sheets, with unfunded commitments reported in other liabilities. At June 30, 2015 , the Company’s balance of LIHTC investments was $494 million and unfunded commitments totaled $323 million . For the three months ended June 30, 2015 , the Company recognized $12 million of amortization expense, $12 million of tax credits and $5 million of other tax benefits associated with these investments in the provision for income taxes. For the six months ended June 30, 2015 , the Company recognized $24 million of amortization expense, $23 million of tax credits and $9 million of other tax benefits associated with these investments in the provision for income taxes. No LIHTC investment impairment losses were recognized during the three and six months ended June 30, 2015 .

The accumulated impairment losses related to the Commercial Banking reporting unit totaled $50 million at June 30, 2015 and 2014 . The Company performs an annual test for impairment of goodwill at a level of reporting referred to as a reporting unit. The Company has identified and allocated goodwill to two reporting units — Consumer Banking and Commercial Banking — based upon reviews of the structure of the Company’s executive team and supporting functions, resource allocations and financial reporting processes. No impairment was recorded for the six months ended June 30, 2015 and 2014 .

MORTGAGE BANKING	MORTGAGE BANKING In its mortgage banking business, the Company sells residential mortgages to government-sponsored entities and other parties, who may issue securities backed by pools of such loans. The Company retains no beneficial interests in these sales, but may retain the servicing rights of the loans sold. The Company is obligated to subsequently repurchase a loan if the purchaser discovers a standard representation or warranty violation such as noncompliance with eligibility requirements, customer fraud, or servicing violations. This primarily occurs during a loan file review. The Company received $1.4 billion and $688 million of proceeds from the sale of residential mortgages for the six months ended June 30, 2015 and 2014 , respectively, and recognized gains on such sales of $32 million and $17 million for the six months ended June 30, 2015 and 2014 , respectively. Pursuant to the standard representations and warranties obligations discussed in the preceding paragraph, the Company repurchased residential mortgage loans totaling $7 million and $17 million for the six months ended June 30, 2015 and 2014 , respectively. Mortgage servicing fees, a component of mortgage banking income, were $28 million and $30 million for the six months ended June 30, 2015 and 2014 , respectively. The Company recorded valuation recoveries of $7 million and $3 million for its MSRs for the six months ended June 30, 2015 and 2014 , respectively. Changes related to MSRs were as follows: As of and for the Six Months Ended June 30, (in millions) 2015 2014 MSRs: Balance as of January 1 $184 $208 Amount capitalized 13 8 Amortization (20 ) (21 ) Carrying amount before valuation allowance 177 195 Valuation allowance for servicing assets: Balance as of January 1 18 23 Valuation recovery (7 ) (3 ) Balance at end of period 11 20 Net carrying value of MSRs $166 $175 MSRs are presented in other assets on the Consolidated Balance Sheets. The fair value of MSRs is estimated using a valuation model that calculates the present value of estimated future net servicing cash flows, taking into consideration actual and expected mortgage loan prepayment rates, discount rates, contractual servicing fee income, servicing costs, default rates, ancillary income, and other economic factors, which are determined based on current market conditions. The valuation model uses a static discounted cash flow methodology incorporating current market interest rates. A static model does not attempt to forecast or predict the future direction of interest rates; rather it estimates the amount and timing of future servicing cash flows using current market interest rates. The current mortgage interest rate influences the expected prepayment rate and therefore, the length of the cash flows associated with the servicing asset, while the discount rate determines the present value of those cash flows. Expected mortgage loan prepayment assumptions are obtained using the QRM Multi Component prepayment model. The Company periodically obtains third-party valuations of its MSRs to assess the reasonableness of the fair value calculated by the valuation model. The key economic assumptions used to estimate the value of MSRs are presented in the following table: (dollars in millions) June 30, 2015 December 31, 2014 Fair value $180 $179 Weighted average life (in years) 5.4 5.2 Weighted average constant prepayment rate 11.7% 12.4% Weighted average discount rate 9.8% 9.8% The key economic assumptions used in estimating the fair value of MSRs capitalized during the period were as follows: Six Months Ended June 30, 2015 2014 Weighted average life (in years) 5.4 5.4 Weighted average constant prepayment rate 11.1% 12.1% Weighted average discount rate 9.6% 10.3% The sensitivity analysis below as of June 30, 2015 and December 31, 2014 presents the impact to current fair value of an immediate 50 basis points and 100 basis points adverse change in the key economic assumptions and presents the decline in fair value that would occur if the adverse change were realized. These sensitivities are hypothetical. The effect of a variation in a particular assumption on the fair value of the mortgage servicing rights is calculated independently without changing any other assumption. In reality, changes in one factor may result in changes in another (e.g., changes in interest rates, which drive changes in prepayment speeds, could result in changes in the discount rates), which might amplify or counteract the sensitivities. The primary risk inherent in the Company’s MSRs is an increase in prepayments of the underlying mortgage loans serviced, which is dependent upon market movements of interest rates. (in millions) June 30, 2015 December 31, 2014 Prepayment rate: Decline in fair value from a 50 basis point decrease in interest rates $6 $9 Decline in fair value from a 100 basis point decrease in interest rates $12 $15 Weighted average discount rate: Decline in fair value from a 50 basis point increase in weighted average discount rate $3 $3 Decline in fair value from a 100 basis point increase in weighted average discount rate $6 $6

Equity [Abstract]
STOCKHOLDERS' EQUITY	STOCKHOLDERS’ EQUITY Preferred Stock As of June 30, 2015 , the Company had 100,000,000 shares authorized and 250,000 shares outstanding of $25.00 par value undesignated preferred stock. The Board of Directors or any authorized committee thereof are authorized to provide for the issuance of these shares in one or more series, and by filing a certificate pursuant to applicable law of the State of Delaware, to establish or change from time to time the number of shares of each such series, and to fix the designations, powers, including voting powers, full or limited, or no voting powers, preferences and the relative, participating, optional or other special rights of the shares of each series and any qualifications, limitations and restrictions thereof. There were no shares of preferred stock issued and outstanding as of December 31, 2014. On April 6, 2015, the Company issued $250 million , or 250,000 shares, of 5.500% fixed-to-floating rate non-cumulative perpetual Series A Preferred Stock, par value of $25.00 per share with a liquidation preference $1,000 per share (the “Preferred Stock”) to the initial purchasers in reliance on the exemption from registration provided by Section (4)(a)(2) of the Securities Act of 1933, as amended, for resale pursuant to Rule 144A and Regulation S under the Securities Act of 1933, as amended. As a result of this issuance, the Company received net proceeds of $247 million after underwriting discount. The Preferred Stock has no stated maturity and is not subject to any sinking fund or other obligation of the Company. Holders of the Preferred Stock will be entitled to receive dividend payments when, and if, declared by the Company’s Board of Directors or a duly authorized committee thereof. Any such dividends will be payable on a semi-annual basis at an annual rate equal to 5.500% . On April 6, 2020, the Preferred Stock converts to a quarterly floating-rate basis equal to three-month U.S. dollar LIBOR on the related dividend determination date plus 3.960% . Citizens may redeem the Preferred Stock, in whole or in part on any dividend payment date, on or after April 6, 2020 or, in whole but not in part, at any time within 90 days following a regulatory capital treatment event at a redemption price equal to $1,000 per share, plus any declared and unpaid dividends, without accumulation of any undeclared dividends. Citizens may not redeem shares of the Preferred Stock without obtaining the prior approval of the FRBG if then required under applicable capital guidelines. Shares of the Preferred Stock have priority over the Company's common stock with regard to the payment of dividends and, as such, the Company may not pay dividends on or repurchase, redeem, or otherwise acquire for consideration shares of its common stock unless dividends for the Preferred Stock have been declared for that period and sufficient funds have been set aside to make payment. Except in certain limited circumstances, the Preferred Stock does not have any voting rights. Treasury Stock On August 3, 2015, CFG used the net proceeds of its public offering of $250 million aggregate principal amount 4.350% Subordinated Notes due 2025 issued on July 31, 2015, to repurchase 9,615,384 shares of its outstanding common stock directly from RBS at a public offering price of $26.00 per share. Immediately following the completion of this stock repurchase transaction, RBS owned 110,461,782 shares, or 20.9% , of CFG’s outstanding common stock. The repurchased shares are held in treasury and will be presented in the Company’s Consolidated Financial Statements beginning in the third quarter of 2015. On April 7, 2015, the Company used the net proceeds of the Preferred Stock offering described above to repurchase 10,473,397 shares of its common stock from RBS at a total cost of approximately $250 million and a price per share of $23.87 , which equaled the volume-weighted average price of the Company’s common stock for all traded volume over the five trading days preceding the repurchase agreement date of April 1, 2015. The repurchased shares are held in treasury. During the six months ended June 30, 2015 , the Company recorded an additional 836,946 shares of treasury stock associated with share-based compensation plan activity for a total cost of $21 million at a weighted-average price per share of $25.48 .

EMPLOYEE BENEFITS

Compensation and Retirement Disclosure [Abstract]
EMPLOYEE BENEFITS	EMPLOYEE BENEFITS Pension Plans The Company maintains a non-contributory pension plan (the “Plan” or “qualified plan”) that was closed to new hires and re-hires effective January 1, 2009, and frozen to all participants effective December 31, 2012. Benefits under the Plan are based on employees’ years of service and highest five-year average eligible compensation. The Plan is funded on a current basis, in compliance with the requirements of ERISA. The Company also provides an unfunded, non-qualified supplemental retirement plan (the “non-qualified plan”), which was closed and frozen consistent with the qualified plan. RBS restructured the administration of employee benefit plans during 2008. As a result, the qualified and non-qualified pension plans of certain RBS subsidiaries referred to as the Company’s “Affiliates” merged with the Company’s pension plans. In September 2014, in preparation for the IPO, the Company divested portions of the qualified and non-qualified plans to newly established plans sponsored by the Affiliates. Citizens remains the sponsor of the original plans, which provides benefits for its current and former employees. RBS is the plan sponsor of the newly established plans, which provide benefits for current and former employees of the Affiliates. As a result of this divestiture, the Company transferred $129 million of plan assets and $148 million of plan liabilities from the qualified plan to the new plan for Affiliates. The Company also transferred liabilities of $7 million related to the non-qualified plan to the new plan established for Affiliates. The Company made a $1 million cash payment to RBS as a result of divesting the portion of the pension and other benefit plans associated with the Affiliates. On February 20, 2015, CFG made a contribution of $100 million to the qualified plan. The following table presents the components of net periodic (income) cost for the Company’s qualified and non-qualified plans: Six Months Ended June 30, Qualified Plan Non-Qualified Plan Total (in millions) 2015 2014 2015 2014 2015 2014 Service cost $2 $2 $— $— $2 $2 Interest cost 22 22 2 2 24 24 Expected return on plan assets (37 ) (35 ) — — (37 ) (35 ) Amortization of actuarial loss 6 4 1 1 7 5 Net periodic pension (income) cost ($7 ) ($7 ) $3 $3 ($4 ) ($4 ) Postretirement Benefits The Company and Affiliates merged their postretirement plans into a single postretirement plan in 2008 and continue to provide health care insurance benefits for certain retired employees and their spouses. In preparation for the IPO, the Company divested the portion of the postretirement plan associated with the Affiliates in September 2014. As a result, in September 2014, the Company transferred liabilities of approximately $7 million to the Affiliates. Employees enrolled in medical coverage immediately prior to retirement and meeting eligibility requirements can elect retiree medical coverage. Employees and covered spouses can continue coverage at the full cost, except for a small group described below. However, coverage must be elected at the time of retirement and cannot be elected at a future date. Spouses may be covered only if the spouse is covered at the time of the employee’s retirement. The Company reviews coverage on an annual basis and reserves the right to modify or cancel coverage at any renewal date. The Company’s cost sharing for certain full-time employees, who were hired prior to August 1, 1993 with 25 years of service who reach retirement age (under age 65) while employed by the Company is 70% ; for those with 15 - 24 years of service, the Company’s share is 50% . Also, the Company shares in the cost for retiree medical benefits for a closed group of grandfathered arrangements from acquisitions. A small, closed group of retirees receive life insurance coverage. Effective July 1, 2014, the Company utilizes a private health care exchange to provide medical and dental benefits to current and future Medicare-eligible plan participants. The Company provides a fixed subsidy to a small, closed group of retirees and spouses based on the subsidy levels prior to July 1, 2014; retirees and spouses pay the cost of benefits in excess of the fixed subsidy.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES Income Tax Provision The provision for income taxes was $92 million and $163 million for the three months ended June 30, 2015 and 2014 , respectively, resulting in an effective tax rate of 32.7% and 34.3% for the three months ended June 30, 2015 and 2014 , respectively. The provision for income taxes was $198 million and $232 million for the six months ended June 30, 2015 and 2014 , respectively, resulting in an effective tax rate of 33.2% and 32.7% for the six months ended June 30, 2015 and 2014 , respectively. For the six months ended June 30, 2015 and 2014 , the effective tax rate compared favorably to the statutory rate of 35% primarily as a result of the permanent benefits of tax credits and tax-exempt income. The effective income tax rate for the six months ended June 30, 2015 reflected the adoption of ASU No. 2014-01, “Accounting for Investments in Qualified Affordable Housing Projects.” The application of this guidance resulted in the reclassification of the amortization of these investments to income tax expense from noninterest income. See Note 5 “Variable Interest Entities,” for further information. Deferred Tax Liability At June 30, 2015 , the Company reported a net deferred tax liability of $558 million , compared to a $493 million liability as of December 31, 2014 . The increase in the net deferred tax liability is primarily attributable to current year timing adjustments.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES	DERIVATIVES In the normal course of business, the Company enters into a variety of derivative transactions in order to meet the financing needs of its customers and to reduce its own exposure to fluctuations in interest rates and foreign currency exchange rates. The Company does not use derivatives for speculative purposes. The Company’s derivative instruments are recognized on the Consolidated Balance Sheets at fair value. Information regarding the valuation methodology and inputs used to estimate the fair value of the Company’s derivative instruments is described in Note 15 “Fair Value Measurements.” The following table identifies derivative instruments included on the Consolidated Balance Sheets in derivative assets and derivative liabilities: June 30, 2015 December 31, 2014 (in millions) Notional Amount (1) Derivative Assets Derivative Liabilities Notional Amount (1) Derivative Assets Derivative Liabilities Derivatives designated as hedging instruments: Interest rate swaps $9,500 $95 $81 $5,750 $24 $99 Derivatives not designated as hedging instruments: Interest rate swaps 33,052 544 459 31,848 589 501 Foreign exchange contracts 7,820 172 167 8,359 170 164 Other contracts 1,310 11 6 730 7 9 Total derivatives not designated as hedging instruments 727 632 766 674 Gross derivative fair values 822 713 790 773 Less: Gross amounts offset in the Consolidated Balance Sheets (2) (157 ) (157 ) (161 ) (161 ) Total net derivative fair values presented in the Consolidated Balance Sheets (3) $665 $556 $629 $612 (1) The notional or contractual amount of interest rate derivatives and foreign exchange contracts is the amount upon which interest and other payments under the contract are based. For interest rate derivatives, the notional amount is typically not exchanged. Therefore, notional amounts should not be taken as the measure of credit or market risk, as they tend to greatly overstate the true economic risk of these contracts. (2) Amounts represent the impact of legally enforceable master netting agreements that allow the Company to settle positive and negative positions. (3) The Company also offsets assets and liabilities associated with repurchase agreements on the Consolidated Balance Sheets. See Note 2 “Securities” for further information. The Company’s derivative transactions are internally divided into three sub-groups: institutional, customer and residential loan. Institutional derivatives The institutional derivatives portfolio primarily consists of interest rate swap agreements that are used to hedge the interest rate risk associated with the Company’s loans and financing liabilities (i.e., borrowed funds, deposits, etc.). The goal of the Company’s interest rate hedging activities is to manage interest rate sensitivity so that movements in interest rates do not significantly adversely affect net interest income. The Company enters into certain interest rate swap agreements to hedge the risk associated with floating rate loans. By entering into pay-floating/receive-fixed interest rate swaps, the Company was able to minimize the variability in the cash flows of these assets due to changes in interest rates. The Company has outstanding interest rate swap agreements designed to hedge a portion of the Company’s borrowed funds and deposits. By entering into a pay-fixed/receive-floating interest rate swap, a portion of these liabilities has been effectively converted to a fixed rate liability for the term of the interest rate swap agreement. Customer derivatives The customer derivatives portfolio consists of interest rate swap agreements and option contracts that are transacted to meet the financing needs of the Company’s customers. Offsetting swap and cap agreements are simultaneously transacted to effectively eliminate the Company’s market risk associated with the customer derivative products. The customer derivatives portfolio also includes foreign exchange contracts that are entered into on behalf of customers for the purpose of hedging exposure related to cash orders and loans and deposits denominated in foreign currency. The primary risks associated with these transactions arise from exposure to changes in foreign currency exchange rates and the ability of the counterparties to meet the terms of the contract. To manage this market risk, the Company simultaneously enters into offsetting foreign exchange contracts. Residential loan derivatives The Company enters into residential loan commitments that allow residential mortgage customers to lock in the interest rate on a residential mortgage while the loan undergoes the underwriting process. The Company also uses forward sales contracts to protect the value of residential mortgage loans and loan commitments that are being underwritten for future sale to investors in the secondary market. The Company has certain derivative transactions that are designated as hedging instruments described as follows: Derivatives designated as hedging instruments The Company’s total institutional hedging portfolio qualifies for hedge accounting. This includes interest rate swaps that are designated in highly effective cash flow hedging relationships. The Company formally documents at inception all hedging relationships, as well as risk management objectives and strategies for undertaking various accounting hedges. Additionally, the Company uses dollar offset or regression analysis at the hedge’s inception, and monthly thereafter to assess whether the derivatives are expected to be, or have been, highly effective in offsetting changes in the hedged item’s expected cash flows. The Company discontinues hedge accounting when it is determined that a derivative is not expected to be or has ceased to be effective as a hedge, and then reflects changes in fair value in earnings after termination of the hedge relationship. Fair value hedges The Company entered into interest rate swap agreements to manage the interest rate exposure on its medium term borrowings. The changes in fair value of the fair value hedges, to the extent that the hedging relationship is effective, are recorded through earnings and offset against changes in the fair value of the hedged item. The following table summarizes certain information related to the Company’s fair value hedges: The Effect of Fair Value Hedges on Net Income Amounts Recognized in Other Income for the Three Months Ended June 30, 2015 Six Months Ended June 30, 2015 (in millions) Derivative Hedged Item Hedge Ineffectiveness Derivative Hedged Item Hedge Ineffectiveness Hedges of interest rate risk on borrowings using interest rate swaps ($3 ) $3 $— $6 ($6 ) $— There was no impact on net income for the three and six months ended June 30, 2014. Cash flow hedges The Company has outstanding interest rate swap agreements designed to hedge a portion of the Company’s floating rate assets and financing liabilities (including its borrowed funds and deposits). All of these swaps have been deemed as highly effective cash flow hedges. The effective portion of the hedging gains and losses associated with these hedges are recorded in OCI; the ineffective portion of the hedging gains and losses is recorded in earnings (other income). Hedging gains and losses on derivative contracts reclassified from OCI to current period earnings are included in the line item in the accompanying Consolidated Statements of Operations in which the hedged item is recorded and in the same period that the hedged item affects earnings. During the next 12 months, approximately $15 million of net loss (pre-tax) on derivative instruments included in OCI is expected to be reclassified to net interest expense in the Consolidated Statements of Operations. Hedging gains and losses associated with the Company’s cash flow hedges are immediately reclassified from OCI to current period earnings (other income) if it becomes probable that the hedged forecasted transactions will not occur during the originally specified time period. The following table summarizes certain information related to the Company’s cash flow hedges: The Effect of Cash Flow Hedges on Net Income and Stockholders' Equity Amounts Recognized for the Three Months Ended June 30, Amounts Recognized for the Six Months Ended June 30, (in millions) 2015 2014 2015 2014 Effective portion of gain (loss) recognized in OCI (1) ($8 ) $97 $96 $191 Amounts reclassified from OCI to interest income (2) 17 18 35 36 Amounts reclassified from OCI to interest expense (2) (14 ) (27 ) (29 ) (56 ) (1) The cumulative effective gains and losses on the Company’s cash flow hedging activities are included on the accumulated other comprehensive loss line item on the Consolidated Balance Sheets. (2) This amount includes both (a) the amortization of effective gains and losses associated with the Company’s terminated cash flow hedges and (b) the current reporting period’s interest settlements realized on the Company’s active cash flow hedges. Both (a) and (b) were previously included on the accumulated other comprehensive loss line item on the Consolidated Balance Sheets and were subsequently recorded as adjustments to the interest expense of the underlying hedged item. Economic hedges The Company’s customer derivatives are recorded on the Consolidated Balance Sheets at fair value. These include interest rate and foreign exchange derivative contracts that are transacted to meet the hedging and financing needs of the Company’s customers. Mark-to-market adjustments to the fair value of customer related interest rate contracts are included in other income in the accompanying Consolidated Statements of Operations. Mark-to-market adjustments to the fair value of foreign exchange contracts relating to foreign currency loans are included in interest and fees on loans and leases in the accompanying Consolidated Statements of Operations, while all other foreign currency contract fair value changes are included in foreign exchange and trade finance fees. In both cases, the mark-to-market gains and losses associated with the customer derivatives are mitigated by the mark-to-market gains and losses on the offsetting interest rate and foreign exchange derivative contracts transacted. The Company’s residential loan derivatives (including residential loan commitments and forward sales contracts) are recorded on the Consolidated Balance Sheets at fair value. Mark-to-market adjustments to the fair value of residential loan commitments and forward sale contracts are included in noninterest income under mortgage banking fees. The following table summarizes certain information related to the Company’s economic hedges: The Effect of Customer Derivatives and Economic Hedges on Net Income Amounts Recognized in Noninterest Income for the Three Months Ended June 30, Amounts Recognized in Noninterest Income for the Six Months Ended June 30, (in millions) 2015 2014 2015 2014 Customer derivative contracts Customer interest rate contracts (1) ($9 ) $88 $64 $149 Customer foreign exchange contracts (1) 18 2 (17 ) 6 Residential loan commitments (2) (7 ) 5 (7 ) 8 Economic hedges Offsetting derivatives transactions to hedge interest rate risk on customer interest rate contracts (1) 17 (82 ) (51 ) (135 ) Offsetting derivatives transactions to hedge foreign exchange risk on customer foreign exchange contracts (3) (19 ) (1 ) 16 (7 ) Forward sale contracts (2) 3 (3 ) 2 (4 ) Total $3 $9 $7 $17 (1) Reported in other income on the Consolidated Statements of Operations.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES The following is a summary of outstanding off-balance sheet arrangements: (in millions) June 30, 2015 December 31, 2014 Commitment amount: Undrawn commitments to extend credit $55,887 $55,899 Financial standby letters of credit 2,181 2,315 Performance letters of credit 55 65 Commercial letters of credit 59 75 Marketing rights 49 51 Risk participation agreements 22 19 Residential mortgage loans sold with recourse 12 11 Total $58,265 $58,435 Commitments to Extend Credit Commitments to extend credit are agreements to lend to customers in accordance with conditions contractually agreed upon in advance. Generally, the commitments have fixed expiration dates or termination clauses and may require payment of a fee. Since many of these commitments are expected to expire without being drawn upon, the contract amounts are not necessarily indicative of future cash requirements. Letters of Credit Standby letters of credit, both financial and performance, are issued by the Company for its customers. They are used as conditional guarantees of payment to a third party in the event the customer either fails to make specific payments (financial) or fails to complete a specific project (performance). Commercial letters of credit are used to facilitate the import of goods. The commercial letter of credit is used as the method of payment to the Company’s customers’ suppliers. The Company’s exposure to credit loss in the event of counterparty nonperformance in connection with the above instruments is represented by the contractual amount of those instruments, net of the value of collateral held. Standby letters of credit and commercial letters of credit are issued for terms of up to ten years and one year , respectively. Generally, letters of credit are collateralized by cash, accounts receivable, inventory or investment securities. Credit risk associated with letters of credit is considered in determining the appropriate amounts of reserves for unfunded commitments. The Company recognizes a liability on the Consolidated Balance Sheets representing its obligation to stand ready to perform over the term of the standby letters of credit in the event that the specified triggering events occur. The liability for these guarantees was $1 million at June 30, 2015 and $3 million at December 31, 2014 . Marketing Rights During 2003, the Company entered into a 25-year agreement to acquire the naming and marketing rights of a baseball stadium in Pennsylvania. The Company paid $2 million for the six months ended June 30, 2015 and $3 million for the year ended December 31, 2014 , respectively, and is obligated to pay $49 million over the remainder of the contract. Risk Participation Agreements RPAs are guarantees issued by the Company to other parties for a fee, whereby the Company agrees to participate in the credit risk of a derivative customer of the other party. Under the terms of these agreements, the “participating bank” receives a fee from the “lead bank” in exchange for the guarantee of reimbursement if the customer defaults on an interest rate swap. The interest rate swap is transacted such that any and all exchanges of interest payments (favorable and unfavorable) are made between the lead bank and the customer. In the event that an early termination of the swap occurs and the customer is unable to make a required close out payment, the participating bank assumes that obligation and is required to make this payment. RPAs where the Company acts as the lead bank are referred to as “participations-out,” in reference to the credit risk associated with the customer derivatives being transferred out of the Company. Participations-out generally occur concurrently with the sale of new customer derivatives. RPAs where the Company acts as the participating bank are referred to as “participations-in,” in reference to the credit risk associated with the counterparty’s derivatives being assumed by the Company. The Company’s maximum credit exposure is based on its proportionate share of the settlement amount of the referenced interest rate swap. Settlement amounts are generally calculated based on the fair value of the swap plus outstanding accrued interest receivables from the customer. The Company’s estimate of the credit exposure associated with its risk participations-in as of June 30, 2015 and December 31, 2014 is $22 million and $19 million , respectively. The current amount of credit exposure is spread out over 80 counterparties. RPAs generally have terms ranging from 1 - 5 years; however, certain outstanding agreements have terms as long as 10 years . Other Commitments In June 2015, the Company entered into an agreement to purchase student loans on a quarterly basis in future periods. Under the terms of the agreement, the Company purchased loans with outstanding balances of $202 million during June 2015 and committed to purchase a minimum of $100 million to a maximum of $163 million per quarter for the subsequent three consecutive quarters through the first quarter 2016. The maximum amount of cumulative loan purchases under the terms of the agreement is $700 million . The agreement may be extended by the mutual agreement of the parties for an additional four quarters. The Company may terminate the agreement at will with payment of a variable termination fee. In June 2015, the Company amended its agreement originally entered into in May 2014, to purchase automobile loans on a quarterly basis in future periods. Commencing on the effective date of June 25, 2015 and through July 31, 2015, the amended agreement requires the purchase of a minimum of $250 million of outstanding balances to a maximum of $600 million per quarterly period. For quarterly periods on or after August 1, 2015, the minimum and maximum purchases are $50 million and $200 million , respectively. The agreement automatically renews until terminated by either party. The Company may cancel the agreement at will with payment of a variable termination fee. After three years, there is no termination fee. In July 2014, the Company created a commercial loan trading desk to provide ongoing secondary market support and liquidity to its clients. Unsettled loan trades (i.e., loan purchase contracts) represent firm commitments to purchase loans from a third party at an agreed-upon price. Principal amounts associated with unsettled commercial loan trades are off-balance sheet commitments until delivery of the loans has taken place. Fair value adjustments associated with each unsettled loan trade are recognized on the Consolidated Balance Sheets and classified within other assets or other liabilities, depending on whether the fair value of the unsettled trade represents an unrealized gain or unrealized loss. The principal balance of unsettled commercial loan trade purchases and sales were $96 million and $102 million at June 30, 2015 , respectively. Settled loans purchased by the trading desk are classified as loans held for sale, at fair value on the Consolidated Balance Sheets. Refer to Note 15 “Fair Value Measurements” for further information. Contingencies The Company operates in a legal and regulatory environment that exposes it to potentially significant risks. A certain amount of litigation ordinarily results from the nature of the Company’s banking and other businesses. The Company is a party to legal proceedings, including class actions. It is also the subject of investigations, reviews, and regulatory matters arising out of its normal business operations, which, in some instances, relate to concerns about unfair and/or deceptive practices and mis-selling of certain products. In addition, the Company engages in discussions with relevant governmental and regulatory authorities on a regular and ongoing basis regarding various issues, and any issues discussed or identified may result in investigatory or other action being taken. Litigation and regulatory matters may result in settlements, damages, fines, penalties, public or private censure, increased costs, required remediation, restrictions on business activities, or other impacts on the Company. In these disputes and proceedings, the Company contests liability and the amount of damages as appropriate. Given their complex nature, it may be years before some of these matters are finally resolved. Moreover, before liability can be reasonably estimated for a claim, numerous legal and factual issues may need to be examined, including through potentially lengthy discovery and determination of important factual matters, and by addressing novel or unsettled legal issues relevant to the proceedings in question. The Company cannot predict with certainty if, how, or when such claims will be resolved or what the eventual settlement, fine, penalty or other relief, if any, may be, particularly for claims that are at an early stage in their development or where claimants seek substantial or indeterminate damages. The Company recognizes a provision for a claim when, in the opinion of management after seeking legal advice, it is probable that a liability exists and the amount of loss can be reasonably estimated. In many proceedings, however, it is not possible to determine whether any loss is probable or to estimate the amount of any loss. In each of the matters described below, the Company is unable to estimate the liability in excess of any provision accrued, if any, that might arise or its effects on the Company’s Consolidated Statements of Operations or Consolidated Cash Flows in any particular period. Set out below are descriptions of significant legal matters involving the Company and its subsidiaries. Based on information currently available, the advice of legal counsel and other advisers, and established reserves, management believes that the aggregate liabilities, if any, potentially arising from these proceedings will not have a materially adverse effect on the Company’s unaudited interim Consolidated Financial Statements. Consumer Products Matters The activities of the Company’s bank subsidiaries are subject to extensive laws and regulations concerning unfair or deceptive acts or practices in connection with customer products. Certain of the bank subsidiaries’ practices with respect to overdraft protection and other consumer products have not met applicable standards. The bank subsidiaries have implemented and are continuing to implement changes to improve and bring their practices in accordance with regulatory guidance. In April 2013, the bank subsidiaries consented to the issuance of orders by the OCC and the FDIC (the Consent Orders). In the Consent Orders (which are publicly available and will remain in effect until terminated by the regulators), the bank subsidiaries neither admitted nor denied the regulators’ findings that they had engaged in deceptive marketing and implementation of the bank’s overdraft protection program, checking rewards programs, and stop-payment process for pre-authorized recurring electronic fund transfers. Under the Consent Orders, the bank subsidiaries paid a total of $10 million in civil monetary penalties and $8 million in restitution to affected customers, agreed to cease and desist any operations in violation of Section 5 of the Federal Trade Commission Act, and submit to the regulators periodic written progress reports regarding compliance with the Consent Orders. In addition, CBNA agreed to take certain remedial actions to improve its compliance risk management systems and to create a comprehensive action plan designed to achieve compliance with the Consent Orders. Restitution plans have been prepared and submitted for approval, and CBNA has submitted for approval, and is in the process of implementing, its action plan for compliance with the Consent Orders, as well as updated policies, procedures, and programs related to its compliance risk management systems. The Company’s banking subsidiaries have engaged in discussions with regulators regarding, among other things, certain identity theft and debt cancellation products, and identifying and correcting errors in customer deposits. The banking subsidiaries have paid restitution regarding some of these past practices and it is probable that there will be additional restitution to certain affected customers in connection with certain of these past practices. In addition, the banking subsidiaries expect to face shortly formal administrative enforcement actions from their federal supervisory agencies, including the assessment of civil monetary penalties and restitution, relating to these past practices, for which we believe that we are fully reserved. Telephone Consumer Protection Act Litigation The Company is a defendant in a purported class action complaint filed in December 2013 in the United States District Court for the Southern District of California pursuant to the Telephone Consumer Protection Act. The named plaintiff purports to represent a “national class” of customers who allegedly received automated calls to their cell phones from the bank or its agents, without customer consent, in violation of the Telephone Consumer Protection Act. The Company is vigorously defending this matter, but is unable to predict the outcome of this matter. LIBOR Litigation The Company is a defendant in lawsuits in which allegations have been made that RBS manipulated U.S. dollar LIBOR to the detriment of the Company’s customers. The lawsuits include a purported class action on behalf of borrowers of the Company whose interest rates were tied to U.S. dollar LIBOR. The plaintiffs in these cases assert various theories of liability, including fraud, negligent misrepresentation, breach of contract, and unjust enrichment. The Company is vigorously defending these matters, but is unable to predict the outcome of these matters. Foreclosure-Related Expenses In May 2013, the civil division of the U.S. Attorney’s Office for the Southern District of New York served a subpoena pursuant to the Financial Institutions Reform, Recovery and Enforcement Act of 1989 seeking information regarding home mortgage foreclosure expenses submitted for reimbursement to the United States Department of Housing and Urban Development, FNMA, or FHLMC. The Company is cooperating with the investigation. Mortgage Repurchase Demands The Company is an originator and servicer of residential mortgages and routinely sells such mortgage loans in the secondary market and to government-sponsored entities. In the context of such sales, the Company makes certain representations and warranties regarding the characteristics of the underlying loans and, as a result, may be contractually required to repurchase such loans or indemnify certain parties against losses for certain breaches of those representations and warranties. Between the start of January 2009 and June 30, 2015 , the Company received approximately $165 million in repurchase demands and $99 million in indemnification payment requests in respect of loans originated, for the most part, since 2003. Of those claims presented, $95 million was paid to repurchase residential mortgage loans, and $33 million was incurred for indemnification costs to make investors whole. The Company repurchased mortgage loans totaling $7 million and $17 million for the six months ended June 30, 2015 and 2014 , respectively. The Company incurred indemnification costs of none and $7 million for the six months ended June 30, 2015 and 2014 , respectively. The Company cannot estimate what the future level of repurchase demands will be or the Company’s ultimate exposure, and cannot give any assurance that its historical experience will continue in the future. The volume of repurchase demands may increase or decrease. In addition to the above, the Company responded to subpoenas issued by the Office of the Inspector General for the Federal Housing Finance Agency in December 2013 which requested information about loans sold to FNMA and the FHLMC from 2003 through 2011. The Company is cooperating with the investigation.

Related Party Transactions [Abstract]
RELATED PARTY TRANSACTIONS	RELATED PARTY TRANSACTIONS As of June 30, 2015, the Company was an indirect subsidiary of RBS. The tables and discussions below present the financial statement effects of significant transactions with RBS. In September 2014, the Company entered into certain agreements that established a framework for its ongoing relationship with RBS. Specifically, the Company entered into the following agreements with RBS: Separation and Shareholder Agreement, Registration Rights Agreement, Trade Mark License Agreement, Amended and Restated Master Services Agreement, and Transitional Services Agreements. These agreements were filed as exhibits in Part II, Item 6 — Exhibits to the Company’s quarterly report on Form 10-Q/A filed November 14, 2014. The following is a summary of borrowed funds from RBS: (dollars in millions) Interest Rate Maturity Date June 30, 2015 December 31, 2014 Subordinated debt 5.158% June 2023 $333 $333 4.771% October 2023 333 333 4.691% January 2024 334 334 4.153% July 2024 333 333 4.023% October 2024 333 333 4.082% January 2025 334 334 The following table presents total interest expense recorded on subordinated debt with RBS: Three Months Ended June 30, Six Months Ended June 30, (in millions) 2015 2014 2015 2014 Interest expense on subordinated debt $20 $13 $40 $25 The Company enters into interest rate swap agreements with RBS for the purpose of reducing the Company’s exposure to interest rate fluctuations. The following table presents a summary of these swap agreements: June 30, 2015 December 31, 2014 (dollars in millions) Notional Fixed Rates Maturity Date Notional Fixed Rates Maturity Date Receive-fixed swaps $4,750 1.66% to 2.04% 2019 - 2023 $4,750 1.66% to 2.04% 2019 - 2023 Pay-fixed swaps 2,500 2.03% to 4.30% 2016 - 2023 1,000 4.18% to 4.30% 2016 Total $7,250 $5,750 The following table presents net interest income (expense) recorded by the Company in relation to interest rate swap agreements with RBS: Three Months Ended Six Months Ended (in millions) 2015 2014 2015 2014 The effect of related party interest rate swap agreements on net interest income (expense) $3 ($10 ) $6 ($21 ) In order to meet the financing needs of its customers, the Company enters into interest rate swap and cap agreements with its customers and simultaneously enters into offsetting swap and cap agreements with RBS. The Company earns a spread equal to the difference between rates charged to the customer and rates charged by RBS. The notional amount of these interest rate swap and cap agreements outstanding with RBS was $8.5 billion and $9.8 billion at June 30, 2015 and December 31, 2014 , respectively. Also to meet the financing needs of its customers, the Company enters into a variety of foreign currency denominated products, such as loans, deposits and foreign exchange contracts. To manage the foreign exchange risk associated with these products, the Company simultaneously enters into offsetting foreign exchange contracts with RBS. The Company earns a spread equal to the difference between rates charged to the customer and rates charged by RBS. The notional amount of foreign exchange contracts outstanding with RBS was $4.0 billion and $4.7 billion at June 30, 2015 and December 31, 2014 , respectively. The following table presents the income (expense) recorded by the Company in relation to the interest rate swap and cap agreements and foreign exchange contracts with RBS: Three Months Ended Six Months Ended (in millions) 2015 2014 2015 2014 The effect of related party interest rate swap and cap agreements on other income $18 ($82 ) ($50 ) ($135 ) The effect of related party foreign exchange contracts on foreign exchange and trade finance fees ($19 ) ($1 ) $16 ($7 ) The Company receives income for providing services and referring customers to RBS. The Company also shares office space with certain RBS entities for which rent expense and/or income is recorded in occupancy expense. Also, the Company receives certain services provided by RBS and by certain RBS entities, the fees for which were recorded in outside services expense. The following table presents the effect of the related party fees on total fee income and outside services: Three Months Ended Six Months Ended (in millions) 2015 2014 2015 2014 The effect of related party service and referral fees, net of occupancy expense, on total fee income $3 $3 $7 $8 The effect of related party service fees on outside services $3 $8 $5 $16 The Company paid $21 million and $10 million in regular common stock dividends to RBS for the three months ended June 30, 2015 and 2014 , respectively, and $60 million and $35 million for the six months ended June 30, 2015 and 2014 , respectively. The Company, as a matter of policy and during the ordinary course of business with underwriting terms similar to those offered to the public, has entered into credit facilities with directors and executive officers and their immediate families, as well as their affiliated companies. Outstanding loan balances amounted to $125 million and $126 million at June 30, 2015 and December 31, 2014 , respectively.

FAIR VALUE MEASUREMENTS

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS As discussed in Note 1 “Significant Accounting Policies,” to the Company’s audited Consolidated Financial Statements in the Annual Report on Form 10-K for the year ended December 31, 2014 , the Company measures or monitors many of its assets and liabilities on a fair value basis. Fair value is used on a recurring basis for assets and liabilities for which fair value is the required or elected measurement basis of accounting. Additionally, fair value is used on a nonrecurring basis to evaluate assets for impairment or for disclosure purposes. Nonrecurring fair value adjustments typically involve the application of lower of cost or market accounting or write-downs of individual assets. The Company also applies the fair value measurement guidance to determine amounts reported for certain disclosures in this Note for assets and liabilities not required to be reported at fair value in the financial statements. Fair Value Option, Residential Mortgage Loans Held for Sale The Company elected to account for residential mortgage loans held for sale at fair value. Applying fair value accounting to the residential mortgage loans held for sale better aligns the reported results of the economic changes in the value of these loans and their related hedge instruments. The fair value of residential loans held for sale is derived from observable mortgage security prices and includes adjustments for loan servicing value, agency guarantee fees, and other loan level attributes which are mostly observable in the marketplace. Credit risk does not significantly impact the valuation since these loans are sold shortly after origination. Therefore, the Company classifies the residential mortgage loans held for sale in Level 2 of the fair value hierarchy. The following table summarizes the difference between the aggregate fair value and the aggregate unpaid principal balance for residential mortgage loans held for sale measured at fair value: June 30, 2015 December 31, 2014 (in millions) Aggregate Fair Value Aggregate Unpaid Principal Aggregate Fair Value Less Aggregate Unpaid Principal Aggregate Fair Value Aggregate Unpaid Principal Aggregate Fair Value Less Aggregate Unpaid Principal Residential mortgage loans held for sale, at fair value $318 $315 $3 $213 $206 $7 The election of the fair value option for financial assets and financial liabilities is optional and irrevocable. The loans accounted for under the fair value option are initially measured at fair value (i.e., acquisition cost) when the financial asset is acquired. Subsequent changes in fair value are recognized in mortgage banking fees on the Consolidated Statement of Operations. The Company recognized mortgage banking (expense) income of ($3) million and $4 million for the three months ended June 30, 2015 and 2014 , respectively. The Company recognized mortgage banking (expense) income of ($2) million and $5 million for the six months ended June 30, 2015 and 2014 , respectively. Interest income on residential mortgage loans held for sale is calculated based on the contractual interest rate of the loan and is recorded in interest income. Fair Value Option, Commercial and Commercial Real Estate Loans Held for Sale The Company elected to account for certain commercial and commercial real estate loans held for sale at fair value. These loans are managed by a commercial secondary loan desk that provides liquidity to banks, finance companies and institutional investors. Applying fair value accounting to this portfolio is appropriate because the Company holds these loans with the intent to sell within short term periods. The fair value of commercial and commercial real estate loans held for sale is estimated using observable prices of identical or similar loans that transact in the marketplace. In addition, the Company uses external pricing services that provide estimates of fair values based on quotes from various dealers transacting in the market, sector curves or benchmarking techniques. Therefore, the Company classifies the commercial and commercial real estate loans managed by the commercial secondary loan desk in Level 2 of the fair value hierarchy given the observable market inputs. The following table summarizes the difference between the aggregate fair value and the aggregate unpaid principal balance for commercial and commercial real estate loans held for sale measured at fair value: June 30, 2015 December 31, 2014 (in millions) Aggregate Fair Value Aggregate Unpaid Principal Aggregate Fair Value Less Aggregate Unpaid Principal Aggregate Fair Value Aggregate Unpaid Principal Aggregate Fair Value Less Aggregate Unpaid Principal Commercial and commercial real estate loans held for sale, at fair value $79 $79 $— $43 $43 $— There were no loans in this portfolio that were 90 days or more past due or nonaccruing as of June 30, 2015 . The loans accounted for under the fair value option are initially measured at fair value when the financial asset is recognized. Subsequent changes in fair value are recognized in current earnings. Since all loans in the Company’s commercial trading portfolio consist of floating rate obligations, all changes in fair value are due to changes in credit risk. Such credit-related fair value changes may include observed changes in overall credit spreads and/or changes to the creditworthiness of an individual borrower. Unsettled trades within the commercial trading portfolio are not recognized on the Consolidated Balance Sheets and represent off-balance sheet commitments. Refer to Note 13 “Commitments and Contingencies” for further information. Interest income on commercial and commercial real estate loans held for sale is calculated based on the contractual interest rate of the loan and is recorded in interest income. Additionally, the Company recognized $1 million and $3 million for the three and six months ended June 30, 2015 , respectively, in other noninterest income related to its commercial trading portfolio. There was no interest income or noninterest income recorded in the three and six months ended June 30, 2014. Recurring Fair Value Measurements The Company utilizes a variety of valuation techniques to measure its assets and liabilities at fair value. Following is a description of valuation methodologies used for significant assets and liabilities carried on the balance sheet at fair value on a recurring basis: Securities Available for Sale The fair value of securities classified as AFS is based upon quoted prices, if available. Where observable quoted prices are available in an active market, securities are classified as Level 1 in the fair value hierarchy. Classes of instruments that are valued using this market approach include debt securities issued by the U.S. Treasury. If quoted market prices are not available, the fair value for the security is estimated by using pricing models, quoted prices of securities with similar characteristics or discounted cash flows. These instruments are classified as Level 2 because they currently trade in active markets and the inputs to the valuations are observable. The pricing models used to value securities generally begin with market prices (or rates) for similar instruments and make adjustments based on the unique characteristics of the instrument being valued. These adjustments reflect assumptions made regarding the sensitivity of each security’s value to changes in interest rates and prepayment speeds. Classes of instruments that are valued using this market approach include residential and commercial CMOs, specified pool mortgage “pass-through” securities and other debt securities issued by U.S. government-sponsored entities and state and political subdivisions. A significant majority of the Company’s Level 1 and 2 securities are priced using an external pricing service. The Company verifies the accuracy of the pricing provided by its primary outside pricing service on a quarterly basis. This process involves using a secondary external vendor to provide valuations for the Company’s securities portfolio for comparison purposes. Any securities with discrepancies beyond a certain threshold are researched and, if necessary, valued by an independent outside broker. In certain cases where there is limited activity or less transparency around inputs to the valuation model, securities are classified as Level 3. Residential loans held for sale See the “ Fair Value Option, Residential Mortgage Loans Held for Sale” discussion above. Commercial loans held for sale See the “ Fair Value Option, Commercial and Commercial Real Estate Loans Held for Sale” discussion above. Derivatives The vast majority of the Company’s derivatives portfolio is composed of “plain vanilla” interest rate swaps, which are traded in over-the-counter markets where quoted market prices are not readily available. For these interest rate derivatives, fair value is determined utilizing models that use primarily market observable inputs, such as swap rates and yield curves. The pricing models used to value interest rate swaps calculate the sum of each instrument’s fixed and variable cash flows, which are then discounted using an appropriate yield curve (i.e., LIBOR or OIS curve) to arrive at the fair value of each swap. The pricing models do not contain a high level of subjectivity as the methodologies used do not require significant judgment. The Company also considers certain adjustments to the modeled price which market participants would make when pricing each instrument, including a credit valuation adjustment that reflects the credit quality of the swap counterparty. The Company incorporates the effect of exposure to a particular counterparty’s credit by netting its derivative contracts with the collateral available and calculating a credit valuation adjustment on the basis of the net position with the counterparty where permitted. The determination of this adjustment requires judgment on behalf of Company management; however, the total amount of this portfolio-level adjustment is not material to the total fair value of the interest rate swaps in their entirety . Therefore, interest rate swaps are classified as Level 2 in the valuation hierarchy. The Company’s other derivatives include foreign exchange contracts. Fair value of foreign exchange derivatives uses the mid-point of daily quoted currency spot prices. A valuation model estimates fair value based on the quoted spot rates together with interest rate yield curves and forward currency rates. Since all of these inputs are observable in the market, foreign exchange derivatives are classified as Level 2 in the fair value hierarchy. Venture capital investments The Company values its venture capital private equity fund investments based on its capital invested in each fund, which is adjusted by management each quarter, if necessary, to arrive at its estimate of fair value. Adjustments for a fund’s underlying investments may be based upon comparisons to public companies, industry benchmarks, current financing round pricing, earnings multiples of comparable companies, current operating performance and future expectations, or third-party valuations. Since the inputs to the valuation are difficult to independently corroborate in the marketplace, and involve a significant degree of management judgment, venture capital investments are classified as Level 3 in the fair value hierarchy. The following table presents assets and liabilities measured at fair value, including gross derivative assets and liabilities on a recurring basis at June 30, 2015 : (in millions) Total Level 1 Level 2 Level 3 Securities available for sale: Mortgage-backed securities $18,606 $— $18,606 $— State and political subdivisions 9 — 9 — Equity securities 17 — 17 — U.S. Treasury 30 30 — — Total securities available for sale 18,662 30 18,632 — Residential loans held for sale 318 — 318 — Commercial loans held for sale 79 — 79 — Total loans held for sale 397 — 397 — Derivative assets: Interest rate swaps 639 — 639 — Foreign exchange contracts 172 — 172 — Other contracts 11 — 11 — Total derivative assets 822 — 822 — Venture capital investments and other investments 5 — 4 1 Total assets $19,886 $30 $19,855 $1 Derivative liabilities: Interest rate swaps $540 $— $540 $— Foreign exchange contracts 167 — 167 — Other contracts 6 — 6 — Total derivative liabilities 713 — 713 — Total liabilities $713 $— $713 $— The following table presents assets and liabilities measured at fair value including gross derivative assets and liabilities on a recurring basis at December 31, 2014 : (in millions) Total Level 1 Level 2 Level 3 Securities available for sale: Mortgage-backed securities $18,606 $— $18,606 $— State and political subdivisions 10 — 10 — Equity securities 25 8 17 — U.S. Treasury 15 15 — — Total securities available for sale 18,656 23 18,633 — Residential loans held for sale 213 — 213 — Commercial loans held for sale 43 — 43 — Total loans held for sale 256 — 256 — Derivative assets: Interest rate swaps 613 — 613 — Foreign exchange contracts 170 — 170 — Other contracts 7 — 7 — Total derivative assets 790 — 790 — Venture capital investments and other investments 5 — — 5 Total assets $19,707 $23 $19,679 $5 Derivative liabilities: Interest rate swaps $600 $— $600 $— Foreign exchange contracts 164 — 164 — Other contracts 9 — 9 — Total derivative liabilities 773 — 773 — Total liabilities $773 $— $773 $— The changes in Level 3 assets measured at fair value on a recurring basis are summarized as follows: Three Months Ended June 30, Six Months Ended June 30, (in millions) 2015 2014 2015 2014 Beginning of period balance $1 $6 $5 $5 Purchases, issuances, sales and settlements: Purchases — — 1 — Sales — — — — Settlements — — — — Other net gains — — — 1 Transfers from Level 3 to Level 2 — — (5 ) — Balance as of period end $1 $6 $1 $6 Net unrealized gain included in net income for the year relating to assets held at period end $— $— $1 $— In March 2015, the Company transferred $5 million of securities from Level 3 to Level 2. The fair values of these securities are based on security prices in the market that are not active. Nonrecurring Fair Value Measurements The following valuation techniques are utilized to measure significant assets for which the Company utilizes fair value on a nonrecurring basis: Impaired Loans The carrying amount of collateral-dependent impaired loans is compared to the appraised value of the collateral less costs to dispose and is classified as Level 2. Any excess of carrying amount over the appraised value is charged to the ALLL. Mortgage Servicing Rights MSRs do not trade in an active market with readily observable prices. MSRs are classified as Level 3 since the valuation methodology utilizes significant unobservable inputs. At June 30, 2015 , the fair value was calculated using a discounted cash flow model, which used assumptions, including weighted-average life of 5.4 years (range of 2.8 - 5.9 years ), weighted-average constant prepayment rate of 11.7% (range of 11.5% - 22.2% ) and weighted-average discount rate of 9.8% (range of 9.1% - 18.1% ). At December 31, 2014 , the fair value was calculated using a discounted cash flow model, which used assumptions, including weighted-average life of 5.2 years (range of 2.8 - 6.6 years ), weighted-average constant prepayment rate of 12.4% (range of 10.4% - 22.6% ) and weighted-average discount rate of 9.8% (range of 9.1% - 12.1% ). Refer to Note 1 “Significant Accounting Policies” to the Company’s audited Consolidated Financial Statements in the Annual Report on Form 10-K for the year ended December 31, 2014 and Note 7 “Mortgage Banking” for more information. Foreclosed assets Foreclosed assets consist primarily of residential properties. Foreclosed assets are carried at the lower of carrying value or fair value less costs to dispose. Fair value is based upon independent market prices or appraised values of the collateral and is classified as Level 2. The following table presents gains (losses) on assets and liabilities measured at fair value on a nonrecurring basis and recorded in earnings: Three Months Ended June 30, Six Months Ended June 30, (in millions) 2015 2014 2015 2014 Impaired collateral-dependent loans ($10 ) ($19 ) ($13 ) ($94 ) MSRs 6 (1 ) 7 3 Foreclosed assets (1 ) — (2 ) (1 ) The following tables present assets and liabilities measured at fair value on a nonrecurring basis: June 30, 2015 December 31, 2014 (in millions) Total Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Impaired collateral-dependent loans $87 $— $87 $— $102 $— $102 $— MSRs 180 — — 180 166 — — 166 Foreclosed assets 34 — 34 — 40 — 40 — Disclosures about Fair Value of Financial Instruments Following is a description of valuation methodologies used to estimate the fair value of financial instruments for disclosure purposes (these instruments are not recorded in the financial statements at fair value): Loans and leases For loans and leases not recorded at fair value on a recurring basis that are not accounted for as collateral-dependent impaired loans, fair value is estimated by using one of two methods: a discounted cash flow method or a securitization method. The discounted cash flow method involves discounting the expected future cash flows using current rates which a market participant would likely use to value similar pools of loans. Inputs used in this method include observable information such as contractual cash flows (net of servicing cost) and unobservable information such as estimated prepayment speeds, credit loss exposures, and discount rates. The securitization method involves utilizing market securitization data to value the assets as if a securitization transaction had been executed. Inputs used include observable market-based MBS data and pricing adjustments based on unobservable data reflecting the liquidity risk, credit loss exposure and other characteristics of the underlying loans. The internal risk-weighted balances of loans are grouped by product type for purposes of these estimated valuations. For nonaccruing loans, fair value is estimated by discounting management’s estimate of future cash flows with a discount rate commensurate with the risk associated with such assets. Fair value of collateral-dependent loans is primarily based on the appraised value of the collateral. Loans held for sale Balances are loans that were transferred to loans held for sale that are reported at book value. Securities Held to Maturity The fair value of securities classified as HTM is estimated using pricing models, quoted prices of securities with similar characteristics or discounted cash flow. The pricing models used to value these securities generally begin with market prices (or rates) for similar instruments and make adjustments based on the unique characteristics of the instrument being valued. These adjustments reflect assumptions made regarding the sensitivity of each security’s value to changes in interest rates and prepayment speeds. Other investment securities The fair value of other investment securities, such as FHLB stock and FRB stock, is assumed to approximate the cost basis of the securities. As a member of the FHLB and FRB, the Company is required to hold FHLB and FRB stock. The stock can be sold only to the FHLB and FRB upon termination of membership, or redeemed at the FHLB’s or FRB’s sole discretion. Deposits The fair value of demand deposits, checking with interest accounts, regular savings and money market accounts is the amount payable on demand at the balance sheet date. The fair value of term deposits is estimated by discounting the expected future cash flows using rates currently offered for deposits of similar remaining maturities. Federal funds purchased and securities sold under agreements to repurchase, other short-term borrowed funds, and long-term borrowed funds Rates currently available to the Company for debt of similar terms and remaining maturities are used to discount the expected cash flows of existing debt. The following table is a summary of fair value for financial instruments not recorded at fair value in the unaudited interim Consolidated Financial Statements.

REGULATORY MATTERS

Banking and Thrift [Abstract]
REGULATORY MATTERS	REGULATORY MATTERS As a BHC, the Company is subject to regulation and supervision by the FRB. The primary subsidiaries of the Company are its two insured depository institutions CBNA, a national banking association whose primary federal regulator is the OCC, and CBPA, a Pennsylvania-chartered savings bank regulated by the Department of Banking of the Commonwealth of Pennsylvania and supervised by the FDIC as its primary federal regulator. Under the Basel III capital framework that took effect on January 1, 2015, the Company and its banking subsidiaries must meet specific capital requirements. Basel III requirements are expressed in terms of the following ratios: (1) common equity tier 1 capital (common equity tier 1 capital/risk-weighted on- and off-balance sheet assets); (2) tier 1 capital (tier 1 capital/risk-weighted on- and off-balance sheet assets); (3) total capital (total capital/risk-weighted on- and off-balance sheet assets); and (4) tier 1 leverage (tier 1 capital/adjusted average quarterly assets). To meet the regulatory capital requirements, the Company and its banking subsidiaries must maintain minimum regulatory levels for each ratio. In addition, the Company must not be subject to a written agreement, order or capital directive with any of its regulators. Failure to meet minimum capital requirements can result in the initiation of certain actions that, if undertaken, could have a material effect on the Company’s Consolidated Financial Statements. The following table presents capital and capital ratio information evidencing the Company’s transition from Basel I regulatory accounting as of December 31, 2014 to Basel III regulatory accounting as of June 30, 2015 . Basel I requirements did not include the common equity tier I capital ratio. Certain Basel III requirements are subject to phase-in through 2018, and these phase-in rules are used in this report of actual regulatory ratios. In addition, the Company has declared itself as an “AOCI opt-out” institution, which means that the Company will not be required to change its methodology for recognizing in regulatory capital only a subset of unrealized gains and losses that are classified as AOCI. As an AOCI opt-out institution, the Company is not required to recognize within regulatory capital the impacts of net unrealized gains and losses on securities AFS, accumulated net gains and losses on cash-flow hedges included in AOCI, net gains and losses on certain defined benefit pension plan assets, and net unrealized gains and losses on securities held to maturity that are included in AOCI. Transitional Basel III FDIC Requirements Actual Minimum Capital Adequacy Classification as Well-capitalized (dollars in millions) Amount Ratio Amount Ratio Amount Ratio As of June 30, 2015 Basel III Common equity tier 1 capital $13,270 11.8 % $5,046 4.5 % $7,289 6.5 % Tier 1 capital to risk-weighted assets 13,517 12.1 6,728 6.0 8,970 8.0 Total capital to risk-weighted assets 17,123 15.3 8,970 8.0 11,213 10.0 Tier 1 capital to average assets (leverage) 13,517 10.4 5,180 4.0 6,475 5.0 As of December 31, 2014 Basel I Tier 1 common equity $13,173 12.4 % Not Applicable Not Applicable Not Applicable Not Applicable Tier 1 capital to risk-weighted assets 13,173 12.4 $4,239 4.0 % $6,358 6.0 % Total capital to risk-weighted assets 16,781 15.8 8,477 8.0 10,596 10.0 Tier 1 capital to average assets (leverage) 13,173 10.6 4,982 4.0 6,227 5.0 In accordance with federal and state banking regulations, dividends paid by the Company’s banking subsidiaries to the Company itself are generally limited to the retained earnings of the respective banking subsidiaries unless specifically approved by the appropriate bank regulator. Common dividends paid in 2014 included a $333 million special dividend, which was paid to RBS concurrently with issuance of tier 2 subordinated debt in the same amount. The Company undertook these paired transactions to reduce excess common equity without impacting the level of total regulatory capital or the total risk-based capital ratio. The earnings impact of goodwill impairment recognized by CBNA has put the bank subsidiary in the position of having to request specific approval from the OCC before executing capital distributions to its parent, CFG. This requirement will be in place through the fourth quarter of 2015 . However, irrespective of the ability of the subsidiary banks to pay dividends, the Company had liquid assets as of June 30, 2015 that were in excess of $383 million on a non-consolidated basis, compared to an annual interest burden on existing subordinated debt of approximately $104 million . On March 13, 2014, the OCC determined that CBNA no longer meets the condition to own a financial subsidiary — namely that CBNA must be both well capitalized and well managed. A financial subsidiary is permitted to engage in a broader range of activities, similar to those of a financial holding company, than those permissible for a national bank itself. CBNA has two financial subsidiaries, Citizens Securities, Inc., a registered broker-dealer, and RBS Citizens Insurance Agency, Inc., a dormant entity, although it continues to collect commissions on certain outstanding insurance policies. CBNA has entered into an agreement with the OCC (the “OCC Agreement”) pursuant to which the Company has developed and submitted to the OCC a remediation plan, that set forth the specific actions it will take to bring itself back into compliance with the conditions to own a financial subsidiary and the schedule for achieving that objective. Until CBNA addresses the deficiencies to the OCC’s satisfaction, CBNA will be subject to restrictions on its ability to acquire control or hold an interest in any new financial subsidiary and to commence new activities in any existing financial subsidiary without the prior consent of the OCC. The OCC Agreement provides that if CBNA fails to remediate the deficiencies it may have to divest itself of its financial subsidiaries and comply with any additional limitations or conditions on its conduct as the OCC may impose.

BUSINESS SEGMENTS

BUSINESS SEGMENTS	6 Months Ended

Segment Reporting [Abstract]
BUSINESS SEGMENTS	BUSINESS SEGMENTS The Company is managed by its CEO on a segment basis. The Company’s two business segments are Consumer Banking and Commercial Banking. The business segments are determined based on the products and services provided, or the type of customer served. Each segment has one or more segment heads who report directly to the CEO. The CEO has final authority over resource allocation decisions and performance assessment. The business segments reflect this management structure and the manner in which financial information is currently evaluated by the CEO. Non-segment operations are classified as Other, which includes corporate functions, the Treasury function, the securities portfolio, wholesale funding activities, intangible assets, community development, non-core assets, and other unallocated assets, liabilities, capital, revenues, provision for credit losses and expenses. Reportable Segments Segment results are determined based upon the Company’s management reporting system, which assigns balance sheet and income statement items to each of the business segments. The process is designed around the Company’s organizational and management structure and, accordingly, the results derived are not necessarily comparable with similar information published by other financial institutions. A description of each reportable segment and table of financial results is presented below: Consumer Banking The Consumer Banking segment focuses on retail customers and small businesses with annual revenues of up to $25 million . It offers traditional banking products and services, including checking, savings, home loans, student loans, credit cards, business loans and financial management services. It also operates an indirect auto financing business, providing financing for both new and used vehicles through auto dealerships. The segment’s distribution channels include a branch network, ATMs and a work force of experienced specialists ranging from financial consultants, mortgage loan officers and business banking officers to private bankers. Our Consumer Banking value proposition is based on providing simple, easy to understand product offerings and a convenient banking experience with a more personalized approach. Commercial Banking The Commercial Banking segment primarily targets companies with annual revenues from $25 million to $2.5 billion and provides a full complement of financial products and solutions, including loans, leases, trade financing, deposits, cash management, commercial cards, foreign exchange, interest rate risk management, corporate finance and capital markets advisory capabilities. It focuses on middle-market companies, large corporations and institutions and has dedicated teams with industry expertise in government banking, not-for-profit, healthcare, technology, professionals, oil & gas, asset finance, franchise finance, asset-based lending, commercial real estate, private equity and sponsor finance. While the segment’s business development efforts are predominantly focused in the Company’s footprint, some of its specialized industry businesses also operate selectively on a national basis (such as healthcare, asset finance and franchise finance). A key component of Commercial Banking’s growth strategy is to bring ideas to clients that help their businesses thrive, and in doing so, expand the loan portfolio and ancillary product sales. Non-segment Operations Other In addition to non-segment operations, Other includes certain reconciling items in order to translate the segment results that are based on management accounting practices into consolidated results. For example, Other includes goodwill and any associated goodwill impairment charges.

The FTP system credits (or charges) the segments with the economic value of the funds created (or used) by the segments. The FTP system provides a funds credit for sources of funds and a funds charge for the use of funds by each segment. The sum of the interest income/expense and FTP charges/credits for each segment is its designated net interest income. The variance between the Company’s cumulative FTP charges and cumulative FTP credits is offset in Other. Provision for credit losses allocations Provision for credit losses is allocated to each business segment based on actual net charge-offs that have been recognized by the business segment. The difference between the consolidated provision for credit losses and the business segments’ net charge-offs is reflected in Other. Income tax allocations Income taxes are assessed to each line of business at a standard tax rate with the residual tax expense or benefit to arrive at the consolidated effective tax rate included in Other. Expense allocations Noninterest expenses incurred by centrally managed operations or business lines that directly support another business line’s operations are charged to the applicable business line based on its utilization of those services. Goodwill For impairment testing purposes, the Company allocates goodwill to its Consumer Banking and Commercial Banking reporting units. For management reporting purposes, the Company presents the goodwill balance (and any related impairment charges) in Other. Substantially all revenues generated and long-lived assets held by the Company’s business segments are derived from clients that reside in the United States. Neither business segment earns revenue from a single external customer that represents 10 percent or more of the Company’s total revenues.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
SHARE-BASED COMPENSATION	SHARE-BASED COMPENSATION During the six months ended June 30, 2015 , the Company granted 1,108,779 Company share-based awards to employees pursuant to the Citizens Financial Group, Inc. 2014 Omnibus Incentive Plan (“Omnibus Plan”) with an aggregate grant date fair value of $28 million , which has been estimated using the fair value of the Company’s shares on the grant date. In addition, during the same period, 31,438 Company share-based awards were granted to non-employee directors pursuant to the Citizens Financial Group, Inc. 2014 Non-Employee Directors Compensation Plan (“Directors Plan”) with an aggregate grant date fair value of $1 million . The total number of Company unvested share-based awards as of June 30, 2015 was 3,441,718 , which includes awards granted under the Citizens Financial Group, Inc. Converted Equity 2010 Deferral Plan and the Citizens Financial Group, Inc. Converted Equity 2010 Long Term Incentive Plan (collectively, the “Converted Equity Plans”), the Omnibus Plan, and the Directors Plan. There are 61 million shares of Company common stock available for awards to be granted under the share plans (including the Citizens Financial Group, Inc. 2014 Employee Stock Purchase Plan (the “ESPP”)). Upon settlement of share-based awards, the Company generally issues new shares, but may also issue shares from treasury stock. Compensation Expense Compensation expense related to the share plans (including the ESPP) was $9 million f or the three months ended June 30, 2015 . There was no compensation expense for the three months ended June 30, 2014. Compensation expense related to the share plans (including the ESPP) was $15 million and $19 million for the six months ended June 30, 2015 and 2014 , respectively. At June 30, 2015 , the total unrecognized compensation expense for nonvested equity awards granted was $24 million . Equity Grants Prior to the IPO Prior to the Company’s IPO, RBS granted share-based compensation awards to employees of the Company pursuant to its various long-term incentive plans, which are administered by the RBS Performance and Remuneration Committee. Below is a summary of those awards. All share-based compensation awards granted to Company employees have been historically settled in RBS shares. Effective as of the IPO, no share-based compensation awards in respect of RBS shares will be granted to Company employees. Restricted Stock Units A restricted stock unit is the right to receive shares of stock on a future date, which may be subject to time-based vesting conditions and/or performance-based vesting conditions. Time-based restricted stock units granted historically have generally become vested ratably over a three -year period. Performance-based restricted stock units granted historically have generally become vested at the end of a three -year performance period, depending on the level of performance achieved during such period. The fair value of each award is determined on the grant date. All awards are expensed on a straight-line basis over the requisite service period. With respect to performance-based awards, over the performance and requisite service period (i.e., vesting period) of the award, the compensation expense and the number of shares of stock expected to be issued are adjusted upward or downward based upon the probability of achievement of performance. Once vesting has occurred, the related compensation cost recognized as expense is based on actual performance and the number of shares actually issued. Special IPO Awards In March 2014, RBS granted special IPO awards to certain Citizens employees. These awards were granted half in the form of restricted stock units in respect of RBS shares and half as a fixed convertible bond. The special IPO awards are scheduled to vest 50% in March 2016 and 50% in March 2017, subject to certain conditions. Pursuant to their terms, upon the closing of the Company’s IPO, these awards were converted into Company restricted stock units and the performance condition was met; however, following the IPO, these awards remain subject to the original vesting schedule and other original terms and conditions. Equity Award Conversion In conjunction with the Company's IPO, any restricted stock units granted by RBS to Company employees that were unvested at the time of the IPO and the bond portion of special IPO awards, were converted into equity-based awards in respect of CFG common stock. Converted awards are governed by the applicable Converted Equity Plan and are generally subject to the same terms and conditions as prior to conversion. However, when the awards become vested and are settled in accordance with their terms, grantees will receive shares of CFG common stock. Following the IPO, no additional awards were granted under the Converted Equity Plans. The number of shares of CFG common stock underlying converted awards was determined by dividing (A) the product of (x) the maximum number of RBS shares underlying the awards outstanding as of the closing of the IPO and (y) the average of the closing prices of RBS shares on each of the 30 London Stock Exchange dealing days immediately prior to the pricing date of the IPO (such 30 -day period, the “Conversion Period”), converted into U.S. Dollars using the average British Pound to U.S. Dollar currency rate over the Conversion Period, by (B) the price per share of CFG common stock on the pricing date of the IPO. The bond portion of the special IPO awards was converted by dividing the bond value by the price per share of CFG common stock on the pricing date of the IPO. During 2014, the Company converted 19,390,752 RBS share awards to 5,249,721 CFG share awards. The difference between the fair value of RBS restricted share units immediately preceding the conversion and the fair value of the CFG equity-based awards granted was not material. The bond portions of the Special IPO awards were converted to 524,783 CFG share awards. Employee Share Plans Following the IPO Omnibus Incentive Plan In connection with the IPO, the Company adopted the Omnibus Plan. This plan permits the Company to grant a variety of awards to employees and service providers. Certain employees have received share grants under this plan as an element of fixed compensation for service in a “Material Risk Taker” role (as defined by the European Banking Authority). These shares were fully vested at grant, but are subject to a retention period which lapses ratably over three to five years. In addition, the Company has also awarded to certain employees immediately vested shares, time-based restricted stock units and performance-based restricted stock units pursuant to the Omnibus Plan. If a dividend is paid on shares underlying the Omnibus Plan awards prior to the date such shares are distributed, those dividends will be distributed following vesting in the same form as the dividend that has been paid to stockholders generally. Director Compensation Plan In connection with the IPO, the Company adopted the Directors Plan. Grants of restricted stock units have been made to the Company’s non-employee directors under this plan as compensation for their services pursuant to the Citizens Financial Group, Inc. Directors Compensation Policy. If a dividend is paid on shares underlying the stock units prior to the date such shares are distributed, those dividends will be distributed following vesting in the same form as the dividend that has been paid to stockholders generally. In the event that a director ceases to serve on the Board of Directors prior to the vesting date for any reason other than under circumstances which would constitute cause, the restricted stock units will fully vest on the date of the director’s cessation from service. Employee Stock Purchase Plan In connection with the IPO, the Company adopted the ESPP, which provides eligible employees an opportunity to purchase its common stock at a 10% discount, through accumulated payroll deductions. Effective as of the fourth quarter of 2014 eligible employees may contribute up to 10% of eligible compensation to the ESPP, except that the limit for the first 2014 offering period was 50% of eligible compensation. No participant may purchase shares in any year with a value exceeding $25,000 . Offering periods under the ESPP are quarterly. Shares of CFG common stock are purchased for a participant on the last day of each quarter at a 10% discount from the fair market value (fair market value under the plan is defined as the closing price on the day of purchase). Prior to the date the shares are purchased, participants do not have any rights or privileges as a stockholder with respect to shares to be purchased at the end of the offering period.

Diluted EPS is computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding during each period, plus the effect of potential dilutive common shares such as share-based awards, using the treasury stock method. Potential dilutive common shares are excluded from the computation of diluted EPS in the periods where the effect would be antidilutive. On August 22, 2014, the Company declared and made effective a 165,582 -for-1 forward stock split of common stock. As a result, all share and per share data have been restated to reflect the effect of the split.

BASIS OF PRESENTATION (Policies

BASIS OF PRESENTATION (Policies)	6 Months Ended
	Jun. 30, 2015
Basis of Presentation [Abstract]
Basis of Presentation	The unaudited interim Consolidated Financial Statements, including the Notes thereto of Citizens Financial Group, Inc., have been prepared in accordance with GAAP interim reporting requirements, and therefore do not include all information and Notes included in the audited Consolidated Financial Statements in conformity with GAAP. These unaudited interim Consolidated Financial Statements and Notes thereto should be read in conjunction with the Company’s audited Consolidated Financial Statements and accompanying Notes included in the Company’s Form 10-K for the year ended December 31, 2014 .
Reclassifications	Certain prior period amounts have been reclassified to conform to current period presentation. These reclassifications had no effect on net income, total comprehensive income, total assets or total stockholders’ equity as previously reported.
Recent Accounting Pronouncements	In April 2015, the FASB issued ASU No. 2015-05 “Intangibles - Goodwill and Other - Internal Use Software” which will assist entities in evaluating the accounting for fees paid by a customer in a cloud computing arrangement. The ASU, which allows for early adoption, is effective for the Company beginning on January 1, 2016. Adoption of this guidance is not expected to have a material impact on the Company’s unaudited interim Consolidated Financial Statements. In April 2015, the FASB issued ASU No. 2015-03 “Interest - Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs”. This standard requires debt issuance costs to be presented in the consolidated balance sheet as a direct deduction from the carrying value of the associated debt liability, consistent with the presentation of a debt discount. The ASU, which allows for early adoption, is effective for the Company beginning on January 1, 2016. Adoption of this guidance is not expected to have a material impact on the Company’s unaudited interim Consolidated Financial Statements. In February 2015, the FASB issued ASU No. 2015-02 “Consolidation (Topic 810): Amendments to the Consolidation Analysis”. This standard focuses on the consolidation evaluation for reporting organizations that are required to evaluate whether they should consolidate certain legal entities such as limited partnerships, limited liability corporations, and securitization structures (e.g., collateralized debt obligations, collateralized loan obligations, and mortgage-backed security transactions). This new standard simplifies consolidation accounting by reducing the number of consolidation models. The ASU will be effective for the Company beginning on January 1, 2016. Early adoption is permitted, including adoption in an interim period. The potential impact the adoption of this guidance will have to the Company’s unaudited interim Consolidated Financial Statements is under review. In January 2015, the FASB issued ASU No. 2015-01 “Income Statement: Extraordinary and Unusual Items.” This ASU eliminates from GAAP the concept of extraordinary items. Accounting Standards Codification Subtopic 225-20 required that an entity separately classify, present, and disclose extraordinary events and transactions that were unusual in nature and infrequent in occurrence. This ASU, which allows for early adoption, is effective for the Company beginning on January 1, 2016. The adoption of this guidance is not expected to have a material impact on the Company’s unaudited interim Consolidated Financial Statements.

Basel I requirements did not include the common equity tier I capital ratio. Certain Basel III requirements are subject to phase-in through 2018, and these phase-in rules are used in this report of actual regulatory ratios. In addition, the Company has declared itself as an “AOCI opt-out” institution, which means that the Company will not be required to change its methodology for recognizing in regulatory capital only a subset of unrealized gains and losses that are classified as AOCI. As an AOCI opt-out institution, the Company is not required to recognize within regulatory capital the impacts of net unrealized gains and losses on securities AFS, accumulated net gains and losses on cash-flow hedges included in AOCI, net gains and losses on certain defined benefit pension plan assets, and net unrealized gains and losses on securities held to maturity that are included in AOCI.

[1]	Amounts represent the impact of legally enforceable master netting agreements that allow the Company to settle positive and negative positions.
[2]	The Company also offsets assets and liabilities associated with repurchase agreements on the Consolidated Balance Sheets. See Note 2 “Securities” for further information.
[3]	The notional or contractual amount of interest rate derivatives and foreign exchange contracts is the amount upon which interest and other payments under the contract are based. For interest rate derivatives, the notional amount is typically not exchanged. Therefore, notional amounts should not be taken as the measure of credit or market risk, as they tend to greatly overstate the true economic risk of these contracts.

[1]	The notional or contractual amount of interest rate derivatives and foreign exchange contracts is the amount upon which interest and other payments under the contract are based. For interest rate derivatives, the notional amount is typically not exchanged. Therefore, notional amounts should not be taken as the measure of credit or market risk, as they tend to greatly overstate the true economic risk of these contracts.
