Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE 1. BASIS OF PRESENTATION Regions Financial Corporation (“Regions” or the "Company”) provides a full range of banking and bank-related services to individual and corporate customers through its subsidiaries and branch offices located across the South, Midwest and Texas as well as delivering specialty capabilities nationwide. Regions is subject to the regulations of certain government agencies and undergoes periodic examinations by certain regulatory authorities. The accounting and reporting policies of Regions and the methods of applying those policies that materially affect the consolidated financial statements conform with GAAP and with general financial services industry practices. The accompanying interim financial statements have been prepared in accordance with the instructions for Form 10-Q and, therefore, do not include all information and notes to the consolidated financial statements necessary for a complete presentation of financial position, results of operations, comprehensive income (loss) and cash flows in conformity with GAAP. In the opinion of management, all adjustments, consisting of normal and recurring items, necessary for the fair presentation of the consolidated financial statements have been included. These interim financial statements should be read in conjunction with the consolidated financial statements and notes thereto in Regions’ Annual Report on Form 10-K for the year ended December 31, 2022. Regions has evaluated all subsequent events for potential recognition and disclosure through the filing date of this Form 10-Q. During 2023, the Company adopted new accounting guidance. See below and Note 12 for related disclosures. MODIFICATIONS TO BORROWERS EXPERIENCING FINANCIAL DIFFICULTY On January 1, 2023, the Company adopted new accounting guidance that eliminated the recognition and measurement guidance for TDRs while enhancing disclosure requirements for certain loan refinancings and restructurings made to borrowers experiencing financial difficulty, also referred to as modifications to troubled borrowers. The guidance also requires disclosure of current-period gross write-offs by year of origination. Regions applied the guidance prospectively, except Regions used the modified-retrospective transition method related to the recognition and measurement of TDRs. The cumulative effect of the modified-retrospective application was a decrease in the allowance of $38 million and an increase to retained earnings of $28 million, net of taxes. Refer to Note 1 "Summary of Significant Accounting Policies" and Note 5 "Allowance for Credit Losses" in the Annual Report on Form 10-K for the year ended December 31, 2022 for additional information regarding TDRs and the related allowance for credit loss accounting prior to the adoption of modifications to troubled borrowers guidance. Modifications to troubled borrowers Modifications to troubled borrowers are loans where the borrower is experiencing financial difficulty at the time of modification and are undertaken in order to improve the likelihood of repayment. Modification types classified as modifications to troubled borrowers include interest rate reductions, other than insignificant term extensions, other than insignificant payment deferrals, principal forgiveness, or any combination of these. Further details are as follows: • Interest rate reduction modifications include instances where the absolute interest rate is reduced as part of the modification. In instances where the rate index changes for variable-rate loans, Regions evaluates whether or not the absolute interest rate decreases from the original rate to the updated rate. • Term extensions are maturity extensions, many of which occur through renewals or restructurings. • Payment deferrals include modifications wherein the contractual payment term is extended. Examples of payment deferral modifications include, but are not limited to, re-agings, payment delays or holidays, lengthening of amortization terms, allowing for an interest-only payment period, and capitalizing interest payments in loan restructurings. • Regions rarely grants principal forgiveness modifications. Modifications to troubled borrowers are subject to policies governing accrual/non-accrual evaluation consistent with all other loans of the same product type as discussed in Note 1 "Summary of Significant Accounting Policies" in the Annual Report on Form 10-K for the year ended December 31, 2022. As such, modifications to troubled borrowers may include loans remaining on non-accrual, moving to non-accrual, or continuing on accrual status, depending on the individual facts and circumstances. Allowance for credit losses The allowance is intended to cover expected credit losses over the contractual life of loans measured at amortized cost, including unfunded commitments. Upon the adoption of modifications to troubled borrowers guidance in January 2023, the Company eliminated TDR and reasonable expectations of a TDR ("RETDR") designations and specific measurement rules within the calculation of the allowance credit losses, which resulted in a decrease to the allowance upon application of the modified-retrospective transition method discussed above. See Note 1 "Summary of Significant Accounting Policies" in the Annual Report on Form 10-K for the year ended December 31, 2022 for previous discussion of allowance measurement methodology for these items. Modifications identified as modifications to troubled borrowers have no separate or distinct allowance measurement rules under the new guidance. As such, these loans are included in their respective loan pools (if they do not qualify for specific evaluation) and expected losses are determined by the Company's allowance models and qualitative framework. FAIR VALUE MEASUREMENTS - FAIR VALUE OF FINANCIAL INSTRUMENTS The method and assumptions used to estimate the fair value of certain financial instruments entered into in 2023 is discussed below. Refer to Note 1 "Summary of Significant Accounting Policies" in the Annual Report on Form 10-K for the year ended December 31, 2022 for additional information regarding fair value measurements.

Debt securities with carrying values of $23.3 billion and $8.8 billion at September 30, 2023 and December 31, 2022, respectively, were pledged to secure public funds, trust deposits and other borrowing arrangements, including the BTFP. Securities that are pledged to secure funding from the BTFP are unencumbered until an advance is taken through the program. The amortized cost and estimated fair value of debt securities held to maturity and debt securities available for sale at September 30, 2023, by contractual maturity, are shown below. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

For debt securities transferred to held to maturity from available for sale, the analysis in the tables below compares the securities' original amortized cost to its current estimated fair value. All securities in an unrealized position are segregated between investments that have been in a continuous unrealized loss position for less than twelve months and for twelve months or more.

The increase in the number of securities and the total amount of unrealized losses from year-end 2022 was primarily due to changes in market interest rates. In instances where an unrealized loss existed, there was no indication of an adverse change in credit on the underlying positions in the tables above. As it relates to these positions, management believes no individual unrealized loss represented credit impairment as of those dates. The Company does not intend to sell, and it is not more likely than not that the Company will be required to sell, the positions before the recovery of their amortized cost basis, which may be at maturity. Gross realized gains and gross realized losses on sales of debt securities available for sale were immaterial for the three and nine months ended September 30, 2023 and 2022. The cost of securities sold is based on the specific identification method. As part of the Company's normal process for evaluating impairment, impairment identified by management was immaterial for the three and nine months ended September 30, 2023. No impairment was identified by management for the three and nine months ended September 30, 2022.

PORTFOLIO SEGMENT RISK FACTORS Regions' portfolio segments are commercial, investor real estate, and consumer. Classes within each segment present unique credit risks. Refer to Note 5 "Allowance for Credit Losses" in the Annual Report on Form 10-K for the year ended December 31, 2022 for information regarding Regions' portfolio segments and related classes, as well as the risks specific to each. CREDIT QUALITY INDICATORS The commercial and investor real estate portfolio segments' primary credit quality indicator is internal risk ratings which are detailed by categories related to underlying credit quality and probability of default. Regions assigns these risk ratings at loan origination and reviews the relationship utilizing a risk-based approach on, at minimum, an annual basis or at any time management becomes aware of information affecting the borrowers' ability to fulfill their obligations. Both quantitative and qualitative factors are considered in this review process. Regions' ratings are aligned to federal banking regulators' definitions and are utilized to develop the associated allowance. Refer to Note 5 "Allowance for Credit Losses" in the Annual Report on Form 10-K for the year ended December 31, 2022 for information regarding commercial risk ratings. Regions' consumer portfolio segment has various classes that present unique credit risks. Regions considers factors such as periodic updates of FICO scores, accrual status, days past due status, unemployment rates, home prices, and geography as credit quality indicators for the consumer loan portfolio. FICO scores are obtained at origination as part of Regions' formal underwriting process. Refreshed FICO scores are obtained by the Company quarterly for all consumer loans, including residential first mortgage loans. Current FICO data is not available for certain loans in the portfolio for various reasons; for example, if customers do not use sufficient credit, an updated score may not be available. These categories are utilized to develop the associated allowance for credit losses. The higher the FICO score the less probability of default and vice versa. The following tables present applicable credit quality indicators for the loan portfolio segments and classes, excluding loans held for sale, by vintage year as of September 30, 2023 and December 31, 2022. Gross charge-offs are also presented by vintage year for the nine months ended September 30, 2023 as a result of the prospective adoption of new accounting guidance. See Note 1 and Note 12 for additional information. Classes in the commercial and investor real estate portfolio segments are disclosed by risk rating. Classes in the consumer portfolio segment are disclosed by current FICO scores. Refer to Note 5 "Allowance for Credit Losses" in the Annual Report on Form 10-K for the year ended December 31, 2022 for more information regarding Regions' credit quality indicators.

Typical modifications include accommodations such as renewals and forbearances. The majority of Regions' commercial and investor real estate modifications to troubled borrowers are the result of renewals of classified loans wherein there has been an interest rate reduction and/or maturity extension (that is considered other than insignificant). Similarly, Regions works to meet the individual needs of troubled consumer borrowers through its CAP. Regions designed the program to allow for customer-tailored modifications with the goal of keeping customers in their homes and avoiding foreclosure where possible. Modifications may be offered to any borrower experiencing financial hardship regardless of the borrower's payment status. Consumer modifications to troubled borrowers primarily involve an interest rate reduction and/or a payment deferral or maturity extension that is considered other than insignificant. All CAP modifications that involve an interest rate reduction, principal forgiveness, other than insignificant payment deferral or term extension and/or a combination of these are disclosed as modifications to troubled borrowers because the customer documents a financial hardship in order to participate. Refer to Note 1 "Basis of Presentation" for additional information regarding the Company's modifications to troubled borrowers. For each portfolio segment and class, the following tables present the end of period balance of new modifications to troubled borrowers and the related percentage of the loan portfolio period-end balance by the type of modification in three and nine months ended September 30, 2023.

As of September 30, 2023, subsequent defaults of the loans restructured as a modification to a troubled borrower during the three and nine-month periods ended September 30, 2023 were immaterial. Prior to the Company’s adoption of new guidance related to modifications to borrowers experiencing financial difficulty, Regions accounted for loans in which the borrower was experiencing financial difficulty at the modification date and wherein Regions had granted a concession to the borrower as a TDR. Like modifications to troubled borrowers, TDRs were undertaken in order to improve the likelihood of repayment of a loan. However, TDR modifications were different because they may have had a stated interest rate lower than the current market rate for new debt with similar risk, other modifications to the structure of the loan that fell outside of normal underwriting policies and procedures, or in limited circumstances forgiveness of principal and/or interest. Refer to Note 1 "Summary of Significant Accounting Policies" and Note 5 "Allowance for Credit Losses" in the Annual Report on Form 10-K for the year ended December 31, 2022 for additional information. The following tables present the end of period balance for loans modified in a TDR during the periods presented in 2022 by portfolio segment and class, and the financial impact of those modifications.

Transfers and Servicing of Financial Assets [Abstract]
Servicing of Financial Assets	NOTE 4. SERVICING OF FINANCIAL ASSETS RESIDENTIAL MORTGAGE BANKING ACTIVITIES The fair value of residential MSRs is calculated using various assumptions including future cash flows, market discount rates, expected prepayment rates, servicing costs and other factors. A significant change in prepayments of mortgages in the servicing portfolio could result in significant changes in the valuation adjustments, thus creating potential volatility in the carrying amount of residential MSRs. The Company compares fair value estimates and assumptions to observable market data where available, and also considers recent market activity and actual portfolio experience. The table below presents an analysis of residential MSRs under the fair value measurement method: Three Months Ended September 30 Nine Months Ended September 30 2023 2022 2023 2022 (In millions) Carrying value, beginning of period $ 801 $ 770 $ 812 $ 418 Additions 8 9 20 38 Purchases (1) 106 25 138 281 Increase (decrease) in fair value: Due to change in valuation inputs or assumptions 45 28 41 127 Economic amortization associated with borrower repayments (2) (28) (23) (79) (55) Carrying value, end of period $ 932 $ 809 $ 932 $ 809 _________ (1) Purchases of residential MSRs can be structured with cash hold back provisions, therefore the timing of payment may be made in future periods. (2) Includes both total loan payoffs as well as partial paydowns. Regions' MSR decay methodology is a discounted net cash flow approach. Data and assumptions used in the fair value calculation, as well as the valuation’s sensitivity to rate fluctuations, related to residential MSRs (excluding related derivative instruments) are as follows: September 30 2023 2022 (Dollars in millions) Unpaid principal balance $ 61,452 $ 53,947 Weighted-average CPR (%) 7.7 % 7.6 % Estimated impact on fair value of a 10% increase $ (59) $ (56) Estimated impact on fair value of a 20% increase $ (100) $ (96) Option-adjusted spread (basis points) 483 479 Estimated impact on fair value of a 10% increase $ (20) $ (17) Estimated impact on fair value of a 20% increase $ (40) $ (35) Weighted-average coupon interest rate 3.7 % 3.5 % Weighted-average remaining maturity (months) 303 309 Weighted-average servicing fee (basis points) 27.3 27.1 The sensitivity calculations above are hypothetical and should not be considered to be predictive of future performance. Changes in fair value based on adverse changes in assumptions generally cannot be extrapolated because the relationship of the change in assumption to the change in fair value may not be linear. Also, the effect of an adverse variation in a particular assumption on the fair value of the residential MSRs is calculated without changing any other assumption, while in reality changes in one factor may result in changes in another, which may either magnify or counteract the effect of the change. The derivative instruments utilized by Regions would serve to reduce the estimated impacts to fair value included in the table above. Servicing related fees, which include contractually specified servicing fees, late fees and other ancillary income resulting from the servicing of residential mortgage loans totaled $42 million and $40 million for the three months ended September 30, 2023 and 2022, respectively and $119 million and $95 million for the nine months ended September 30, 2023 and 2022, respectively. Residential mortgage loans are sold in the secondary market with standard representations and warranties regarding certain characteristics such as the quality of the loan, the absence of fraud, the eligibility of the loan for sale and the future servicing associated with the loan. Regions may be required to repurchase these loans at par, or make-whole or indemnify the purchasers for losses incurred when representations and warranties are breached. Regions maintains an immaterial repurchase liability related to residential mortgage loans sold with representations and warranty provisions. This repurchase liability is reported in other liabilities on the consolidated balance sheets and reflects management’s estimate of losses based on historical repurchase and loss trends, as well as other factors that may result in anticipated losses different from historical loss trends. Adjustments to this reserve are recorded in other non-interest expense on the consolidated statements of income. COMMERCIAL MORTGAGE BANKING ACTIVITIES Regions is an approved DUS lender. The DUS program provides liquidity to the multi-family housing market. In connection with the DUS program, Regions services commercial mortgage loans, retains commercial MSRs and intangible assets associated with the DUS license, and assumes a loss share guarantee associated with the loans. See Note 1 "Summary of Significant Accounting Policies" in the Annual Report on Form 10-K for the year ended December 31, 2022 for additional information. Also see Note 11 for additional information related to the guarantee. Regions' DUS portfolio totaled $85 million and $81 million at September 30, 2023 and December 31, 2022, respectively. Regions periodically evaluates DUS MSRs for impairment based on fair value. The estimated fair value of the DUS MSRs was approximately $110 million at September 30, 2023 and $96 million at December 31, 2022. Servicing related fees in connection with the DUS program, which include contractually specified servicing fees, late fees and other ancillary income resulting from the servicing of DUS commercial mortgage loans totaled $5 million and $6 million for the three months ended September 30, 2023 and 2022, respectively and $17 million and $20 million for the nine months ended September 30, 2023 and 2022, respectively.

(2) Dividends, if declared, will be paid quarterly at an annual rate equal to (i) for each period beginning prior to September 15, 2024, 6.375%, and (ii) for each period beginning on or after September 15, 2024, three- month CME Term SOFR plus 3.536%. (3) Dividends, if declared, will be paid quarterly at an annual rate equal to (i) for each period beginning prior to August 15, 2029, 5.700%, and (ii) for each period beginning on or after August 15, 2029, three-month CME Term SOFR plus 3.148%. (4) Dividends, if declared, will be paid quarterly at an annual rate equal to (i) for each period beginning prior to September 15, 2025, 5.750%, and (ii) for each period beginning on or after September 15, 2025, the five-year treasury rate as of the most recent reset dividend determination date plus 5.426%. All series of preferred stock have no stated maturity and redemption is solely at Regions' option, subject to regulatory approval, in whole, or in part, after the earliest redemption date or in whole, but not in part, at any time following a regulatory capital treatment event for the Series B, Series C, Series D, and Series E preferred stock. The Board of Directors declared a total of $74 million in cash dividends on all series of preferred stock during both the first nine months of 2023 and 2022. In the event Series B, Series C, Series D or Series E preferred shares are redeemed at the liquidation amounts, $67 million, $10 million, $4 million, or $10 million in excess of the redemption amount over the carrying amount will be recognized, respectively. Approximately $52 million of Series B preferred dividends that were recorded as a reduction of preferred stock, including related surplus, will be recorded as a reduction to common shareholders' equity. The remaining amounts listed represent issuance costs that were recorded as reductions to preferred stock, including related surplus, and will be recorded as reductions to net income available to common shareholders. COMMON STOCK Regions' 2022 stress testing results from the FRB reflected that the Company exceeded all minimum capital levels and the SCB will be floored at 2.5 percent for the fourth quarter of 2022 through the third quarter of 2023. As a Category IV bank, Regions was not required to participate in this year's supervisory capital stress test; however, the Company did receive its SCB reflecting planned capital changes including plans to increase its common stock dividend. From the fourth quarter of 2023 through the third quarter of 2024, the Company's SCB will remain at 2.5 percent. On April 20, 2022, the Board authorized the repurchase of up to $2.5 billion of the Company's common stock, permitting purchases from the second quarter of 2022 through the fourth quarter of 2024. As of September 30, 2023, Regions had repurchased approximately 725 thousand shares of common stock at a total cost of $15 million under this plan. All of these shares were immediately retired upon repurchase and therefore were not included in treasury stock. In the third quarter of 2023, the Board declared a cash dividend of $0.24 per share, a 20 percent increase to the quarterly common stock dividend. The cash dividends declared for the first and second quarter of 2023 were $0.20 per share. Therefore, Regions declared a total of $0.64 per common share for the first nine months of 2023 as compared to $0.54 per common share for the first nine months of 2022.

The table reflects net notional presentation and gross asset and liability presentation to capture the economic impact of the trades. As a part of this transition, the Company is applying certain optional expedients and exceptions in previously adopted accounting relief for hedges. (2) Derivatives in a gain position are recorded as other assets and derivatives in a loss position are recorded as other liabilities on the consolidated balance sheets. Includes accrued interest as applicable. (3) Netting adjustments represent amounts recorded to convert derivative assets and derivative liabilities from a gross basis to a net basis in accordance with applicable accounting guidance. The net basis takes into account the impact of cash collateral received or posted, legally enforceable master netting agreements, and variation margin that allow Regions to settle derivative contracts with the counterparty on a net basis and to offset the net position with the related cash collateral. HEDGING DERIVATIVES Derivatives entered into to manage interest rate risk and facilitate asset/liability management strategies are designated as hedging derivatives. Derivative financial instruments that qualify in a hedging relationship are classified, based on the exposure being hedged, as either fair value hedges or cash flow hedges. See Note 1 "Summary of Significant Accounting Policies" of the Annual Report on Form 10-K for the year ended December 31, 2022, for additional information regarding accounting policies for derivatives. FAIR VALUE HEDGES Fair value hedge relationships mitigate exposure to the change in fair value of an asset, liability or firm commitment. Regions enters into interest rate swap agreements to manage interest rate exposure on the Company’s fixed-rate borrowings. These agreements involve the receipt of fixed-rate amounts in exchange for floating-rate interest payments over the life of the agreements. Regions also enters into interest rate swap agreements to manage interest rate exposure on certain of the Company's fixed-rate prepayable and non-prepayable debt securities available for sale. These agreements involve the payment of fixed-rate amounts in exchange for floating-rate interest receipts. CASH FLOW HEDGES Cash flow hedge relationships mitigate exposure to the variability of future cash flows or other forecasted transactions. Regions enters into interest rate swaps, options (e.g., floors, caps and collars), and agreements with a combination of these instruments to manage overall cash flow changes related to interest rate risk exposure on variable rate loans. The agreements effectively modify the Company’s exposure to interest rate risk by utilizing receive fixed/pay LIBOR or SOFR interest rate swaps and interest rate floors. As of September 30, 2023, Regions is hedging its exposure to the variability in future cash flows into 2030. As of September 30, 2023, cash flow hedges were held at a pre-tax net loss of $1.0 billion, which includes pre-tax net gains of $93 million related to terminated cash flow floors and swaps. Regions expects to reclassify into earnings approximately $432 million in pre-tax expenses due to the net receipt/ payment of interest and amortization on all cash flow hedges within the next twelve months. Included in this amount is $49 million in pre-tax net gains related to the amortization of terminated cash flow floors and swaps.

DERIVATIVES NOT DESIGNATED AS HEDGING INSTRUMENTS The Company holds a portfolio of interest rate swaps, option contracts, and futures and forward commitments that result from transactions with its commercial customers in which they manage their risks by entering into a derivative with Regions. The Company monitors and manages the net risk in this customer portfolio and enters into separate derivative contracts in order to reduce the overall exposure to pre-defined limits. For both derivatives with its end customers and derivatives Regions enters into to mitigate the risk in this portfolio, the Company is subject to market risk and the risk that the counterparty will default. The contracts in this portfolio are not designated as accounting hedges and are marked-to market through earnings (in capital markets income) and included in other assets and other liabilities, as appropriate. Regions enters into interest rate lock commitments, which are commitments to originate mortgage loans whereby the interest rate on the loan is determined prior to funding and the customers have locked into that interest rate. At September 30, 2023 and December 31, 2022, Regions had $169 million and $118 million, respectively, in total notional amount of interest rate lock commitments. Regions manages market risk on interest rate lock commitments and mortgage loans held for sale with corresponding forward sale commitments. Residential mortgage loans held for sale are recorded at fair value with changes in fair value recorded in mortgage income. Commercial mortgage loans held for sale are recorded at either the lower of cost or market or at fair value based on management's election. At September 30, 2023 and December 31, 2022, Regions had $330 million and $233 million, respectively, in total notional amounts related to these forward sale commitments. Changes in mark-to-market from both interest rate lock commitments and corresponding forward sale commitments related to residential mortgage loans are included in mortgage income. Changes in mark-to-market from both interest rate lock commitments and corresponding forward sale commitments related to commercial mortgage loans are included in capital markets income. Regions has elected to account for residential MSRs at fair value with any changes to fair value recorded in mortgage income. Concurrent with the election to use the fair value measurement method, Regions began using various derivative instruments in the form of forward rate commitments, futures contracts, swaps and swaptions to mitigate the effect of changes in the fair value of its residential MSRs in its consolidated statements of income. As of September 30, 2023 and December 31, 2022, the total notional amount related to these contracts was $3.3 billion and $3.4 billion, respectively. The following table presents the location and amount of gain or (loss) recognized in income on derivatives not designated as hedging instruments in the consolidated statements of income for the periods presented below: Three Months Ended September 30 Nine Months Ended September 30 Derivatives Not Designated as Hedging Instruments 2023 2022 2023 2022 (In millions) Capital markets income: Interest rate swaps $ 16 $ 44 $ (8) $ 111 Interest rate options 14 4 35 20 Interest rate futures and forward commitments 2 8 10 7 Other contracts 4 11 10 19 Total capital markets income 36 67 47 157 Mortgage income: Interest rate swaps (38) (28) (38) (112) Interest rate options (1) (8) — (17) Interest rate futures and forward commitments (4) 19 (4) 14 Total mortgage income (43) (17) (42) (115) $ (7) $ 50 $ 5 $ 42 CREDIT DERIVATIVES Regions has both bought and sold credit protection in the form of participations on interest rate swaps (swap participations). These swap participations, which meet the definition of credit derivatives, were entered into in the ordinary course of business to serve the credit needs of customers. Swap participations, whereby Regions has purchased credit protection, entitle Regions to receive a payment from the counterparty if the customer fails to make payment on any amounts due to Regions upon early termination of the swap transaction and have maturities between 2023 and 2029. Swap participations, whereby Regions has sold credit protection have maturities between 2023 and 2035. For contracts where Regions sold credit protection, Regions would be required to make payment to the counterparty if the customer fails to make payment on any amounts due to the counterparty upon early termination of the swap transaction. Regions bases the current status of the prepayment/performance risk on bought and sold credit derivatives on recently issued internal risk ratings consistent with the risk management practices of unfunded commitments. Regions’ maximum potential amount of future payments under these contracts as of September 30, 2023 was approximately $443 million. This scenario occurs if variable interest rates were at zero percent and all counterparties defaulted with zero recovery. The fair value of sold protection at September 30, 2023 and 2022 was immaterial. In transactions where Regions has sold credit protection, recourse to collateral associated with the original swap transaction is available to offset some or all of Regions’ obligation. Regions has bought credit protection in the form of credit default indices. These indices, which meet the definition of credit derivatives, were entered into in the ordinary course of business to economically hedge credit spread risk in commercial mortgage loans held for sale whereby the fair value option has been elected. Credit derivatives, whereby Regions has purchased credit protection, entitle Regions to receive a payment from the counterparty if losses on the underlying index exceed a certain threshold, dependent upon the tranche rating of the capital structure. CONTINGENT FEATURES Certain of Regions’ derivative instrument contracts with broker-dealers contain credit-related termination provisions and/or credit related provisions regarding the posting of collateral, allowing those broker-dealers to terminate the contracts in the event that Regions’ and/or Regions Bank’s credit ratings falls below specified ratings from certain major credit rating agencies. The aggregate fair values of all derivative instruments with any credit-risk-related contingent features that were in a liability position on September 30, 2023 and December 31, 2022, were $48 million and $17 million, respectively, for which Regions had posted collateral of $49 million and $20 million, respectively, in the normal course of business.

Fair Value Disclosures [Abstract]
Fair Value Measurements	NOTE 9. FAIR VALUE MEASUREMENTS See Note 1 "Summary of Significant Accounting Policies" to the consolidated financial statements of the Annual Report on Form 10-K for the year ended December 31, 2022 for a description of valuation methodologies for assets and liabilities measured at fair value on a recurring and non-recurring basis. Assets and liabilities measured at fair value rarely transfer between Level 1 and Level 2 measurements. Marketable equity securities and debt securities available for sale may be periodically transferred to or from Level 3 valuation based on management’s conclusion regarding the observability of inputs used in valuing the securities. Such transfers are accounted for as if they occur at the beginning of a reporting period. The following table presents assets and liabilities measured at estimated fair value on a recurring basis: September 30, 2023 December 31, 2022 Level 1 Level 2 Level 3 (1) Total Level 1 Level 2 Level 3 (1) Total (In millions) Recurring fair value measurements Debt securities available for sale: U.S. Treasury securities $ 1,186 $ — $ — $ 1,186 $ 1,187 $ — $ — $ 1,187 Federal agency securities — 1,004 — 1,004 — 836 — 836 Obligations of states and political subdivisions — 2 — 2 — 2 — 2 Mortgage-backed securities: Residential agency — 15,740 — 15,740 — 16,954 — 16,954 Residential non-agency — — — — — — 1 1 Commercial agency — 7,158 — 7,158 — 7,613 — 7,613 Commercial non-agency — 78 — 78 — 186 — 186 Corporate and other debt securities — 1,059 1 1,060 — 1,153 1 1,154 Total debt securities available for sale $ 1,186 $ 25,041 $ 1 $ 26,228 $ 1,187 $ 26,744 $ 2 $ 27,933 Loans held for sale $ — $ 217 $ 62 $ 279 $ — $ 177 $ 19 $ 196 Marketable equity securities in other earning assets $ 745 $ — $ — $ 745 $ 529 $ — $ — $ 529 Residential mortgage servicing rights $ — $ — $ 932 $ 932 $ — $ — $ 812 $ 812 Derivative assets (2) : Interest rate swaps $ — $ 2,728 $ — $ 2,728 $ — $ 2,335 $ — $ 2,335 Interest rate options — 91 8 99 — 91 3 94 Interest rate futures and forward commitments — 8 — 8 — 8 — 8 Other contracts — 144 — 144 3 169 — 172 Total derivative assets $ — $ 2,971 $ 8 $ 2,979 $ 3 $ 2,603 $ 3 $ 2,609 Derivative liabilities (2) : Interest rate swaps $ — $ 3,996 $ — $ 3,996 $ — $ 3,161 $ — $ 3,161 Interest rate options — 93 — 93 — 85 — 85 Interest rate futures and forward commitments — 7 — 7 — 5 — 5 Other contracts 11 118 1 130 2 124 1 127 Total derivative liabilities $ 11 $ 4,214 $ 1 $ 4,226 $ 2 $ 3,375 $ 1 $ 3,378 _________ (1) All following disclosures related to Level 3 recurring assets do not include those deemed to be immaterial. (2) As permitted under U.S. GAAP, variation margin collateral payments made or received for derivatives that are centrally cleared are legally characterized as settled. As such, these derivative assets and derivative liabilities and the related variation margin collateral are presented on a net basis on the balance sheet. Assets and liabilities in all levels could result in volatile and material price fluctuations. Realized and unrealized gains and losses on Level 3 assets represent only a portion of the risk to market fluctuations in Regions’ consolidated balance sheets. Further, derivatives included in Levels 2 and 3 are used by ALCO in a holistic approach to managing price fluctuation risks. The following tables present an analysis of residential MSRs for the three and nine months ended September 30, 2023 and 2022, respectively. . Residential mortgage servicing rights Three Months Ended September 30 Nine Months Ended September 30 2023 2022 2023 2022 (In millions) Carrying value, beginning of period $ 801 $ 770 $ 812 $ 418 Total realized/unrealized gains (losses) included in earnings (1) 17 5 (38) 72 Additions 8 9 20 38 Purchases 106 25 138 281 Carrying value, end of period $ 932 $ 809 $ 932 $ 809 _________ (1) Included in mortgage income. Amounts presented exclude offsetting impact from related derivatives. RECURRING FAIR VALUE MEASUREMENTS USING SIGNIFICANT UNOBSERVABLE INPUTS Residential mortgage servicing rights The significant unobservable inputs used in the fair value measurement of residential MSRs are OAS and CPR. This valuation requires generating cash flow projections over multiple interest rate scenarios and discounting those cash flows at a risk-adjusted rate. Additionally, the impact of prepayments and changes in the OAS are based on a variety of underlying inputs including servicing costs. Increases or decreases to the underlying cash flow inputs will have a corresponding impact on the value of the MSR asset. The net change in unrealized gains (losses) included in earnings related to MSRs held at period end are disclosed as the changes in valuation inputs or assumptions included in the MSR rollforward table in Note 4 . The following tables present detailed information regarding material assets and liabilities measured at fair value using significant unobservable inputs (Level 3) as of September 30, 2023, and December 31, 2022. The tables include the valuation techniques and the significant unobservable inputs utilized. The range of each significant unobservable input as well as the weighted-average within the range utilized at September 30, 2023 and December 31, 2022 are included. Following the tables are descriptions of the valuation techniques and the sensitivity of the techniques to changes in the significant unobservable inputs.

FAIR VALUE OPTION The Company elected the option to measure certain commercial mortgage loans held for sale at fair value. Commercial mortgage loans held for sale are valued based on traded market prices for comparable commercial mortgage-backed securitizations, into which the loans will be placed, adjusted for movements of interest rates and credit spreads. At September 30, 2023 and December 31, 2022, the balance of these loans was immaterial. The Company has elected the option to measure certain commercial and industrial loans held for sale at fair value, as these loans are actively traded in the secondary market. The Company is able to obtain fair value estimates for substantially all of these loans through a third party valuation service that is broadly used by market participants. While most of the loans are traded in the market, the volume and level of trading activity is subject to variability and the loans are not exchange-traded. The balance of these loans held for sale was immaterial at September 30, 2023 and December 31, 2022. Regions has elected the fair value option for all eligible agency residential first mortgage loans originated with the intent to sell. This election allows for a more effective offset of the changes in fair values of the loans and the derivative instruments used to economically hedge them without the burden of complying with the requirements for hedge accounting. Fair values of residential first mortgage loans held for sale are based on traded market prices of similar assets where available and/or discounted cash flows at market interest rates, adjusted for securitization activities that include servicing values and market conditions, and are recorded in loans held for sale. At September 30, 2023, the aggregate fair value of these loans totaled $195 million compared to aggregate unpaid principal of $193 million. At December 31, 2022 the aggregate fair value of these loans totaled $160 million compared to aggregate unpaid principal of $157 million. Interest income on mortgage loans held for sale is recognized based on contractual rates and is reflected in interest income on loans held for sale. The following details net gains and losses resulting from changes in fair value of residential mortgage loans held for sale, which were recorded in mortgage income in the consolidated statements of income during the three and nine months ended September 30, 2023 and 2022. A net loss resulting from changes in fair value of residential mortgage loans held for sale totaled $2 million and $1 million for the three months and nine months ended September 30, 2023, respectively. Net losses resulting from changes in fair value of residential mortgage loans held for sale totaled $11 million and $27 million for the three and nine months ended September 30, 2022, respectively. These changes in fair value are mostly offset by economic hedging activities. An immaterial portion of these amounts was attributable to changes in instrument-specific credit risk. NON-RECURRING FAIR VALUE MEASUREMENTS Items measured at fair value on a non-recurring basis include loans held for sale for which the fair value option has not been elected, foreclosed property and other real estate and equity investments without a readily determinable fair value; all of which may be considered either Level 2 or Level 3 valuation measurements. Non-recurring fair value adjustments related to loans held for sale, foreclosed property and other real estate are typically a result of the application of lower of cost or fair value accounting during the period. Non-recurring fair value adjustments related to equity investments without readily determinable fair values are the result of impairments or price changes from observable transactions. The balances of each of these assets, as well as the related fair value adjustments during the periods, were immaterial at both September 30, 2023 and December 31, 2022. FAIR VALUE OF FINANCIAL INSTRUMENTS The carrying amounts and estimated fair values, as well as the level within the fair value hierarchy, of the Company’s financial instruments as of September 30, 2023 are as follows: September 30, 2023 Carrying Estimated Fair Value (1) Level 1 Level 2 Level 3 (In millions) Financial assets: Cash and cash equivalents $ 9,016 $ 9,016 $ 9,016 $ — $ — Debt securities held to maturity 763 703 — 703 — Debt securities available for sale 26,228 26,228 1,186 25,041 1 Loans held for sale 459 459 — 397 62 Loans (excluding leases), net of unearned income and allowance for loan losses (2)(3) 95,753 90,849 — — 90,849 Other earning assets 1,552 1,552 745 807 — Derivative assets 2,979 2,979 — 2,971 8 Financial liabilities: Derivative liabilities 4,226 4,226 11 4,214 1 Deposits with no stated maturity (4) 113,006 113,006 — 113,006 — Time deposits (4) 13,193 13,095 — 13,095 — Short-term borrowings 2,000 2,000 — 2,000 — Long-term borrowings 4,290 4,256 — 4,255 1 Loan commitments and letters of credit 157 157 — — 157 _________ (1) Estimated fair values are consistent with an exit price concept. The assumptions used to estimate the fair values are intended to approximate those that a market participant would use in a hypothetical orderly transaction. In estimating fair value, the Company makes adjustments for estimated changes in interest rates, market liquidity and credit spreads in the periods they are deemed to have occurred. (2) The estimated fair value of portfolio loans assumes sale of the loans to a third-party financial investor. Accordingly, the value to the Company if the loans were held to maturity is not reflected in the fair value estimate. The fair value discount on the loan portfolio's net carrying amount at September 30, 2023 was $4.9 billion or 5.1 percent. (3) Excluded from this table is the sales-type, direct financing, and leveraged lease carrying amount of $1.6 billion at September 30, 2023. (4) The fair value of non-interest-bearing demand accounts, interest-bearing checking accounts, savings accounts, and money market accounts is the amount payable on demand at the reporting date (i.e., the carrying amount) as these instruments have an indeterminate maturity date. Fair values for time deposits are estimated by using discounted cash flow analyses, based on market spreads to benchmark rates. The carrying amounts and estimated fair values, as well as the level within the fair value hierarchy, of the Company's financial instruments as of December 31, 2022 are as follows: December 31, 2022 Carrying Estimated Fair Value (1) Level 1 Level 2 Level 3 (In millions) Financial assets: Cash and cash equivalents $ 11,227 $ 11,227 $ 11,227 $ — $ — Debt securities held to maturity 801 751 — 751 — Debt securities available for sale 27,933 27,933 1,187 26,744 2 Loans held for sale 354 354 — 335 19 Loans (excluding leases), net of unearned income and allowance for loan losses (2)(3) 94,044 89,540 — — 89,540 Other earning assets 1,308 1,308 529 779 — Derivative assets 2,609 2,609 3 2,603 3 Financial liabilities: Derivative liabilities 3,378 3,378 2 3,375 1 Deposits with no stated maturity (4) 125,971 125,971 — 125,971 — Time deposits (4) 5,772 5,697 — 5,697 — Long-term borrowings 2,284 2,376 — 2,375 1 Loan commitments and letters of credit 153 153 — — 153 _________ (1) Estimated fair values are consistent with an exit price concept. The assumptions used to estimate the fair values are intended to approximate those that a market participant would use in a hypothetical orderly transaction. In estimating fair value, the Company makes adjustments for estimated changes in interest rates, market liquidity and credit spreads in the periods they are deemed to have occurred. (2) The estimated fair value of portfolio loans assumes sale of the loans to a third-party financial investor. Accordingly, the value to the Company if the loans were held to maturity is not reflected in the fair value estimate. The fair value discount on the loan portfolio's net carrying amount at December 31, 2022 was $4.5 billion or 4.8 percent. (3) Excluded from this table is the sales-type, direct financing, and leveraged lease carrying amount of $1.5 billion at December 31, 2022. (4) The fair value of non-interest-bearing demand accounts, interest-bearing checking accounts, savings accounts, and money market accounts is the amount payable on demand at the reporting date (i.e., the carrying amount) as these instruments have an indeterminate maturity date. Fair values for time deposits are estimated by using discounted cash flow analyses, based on market spreads to benchmark rates.

Segment Reporting [Abstract]
Business Segment Information	NOTE 10. BUSINESS SEGMENT INFORMATION Each of Regions’ reportable segments is a strategic business unit that serves specific needs of Regions’ customers based on the products and services provided. The segments are based on the manner in which management views the financial performance of the business. The Company has three reportable segments: Corporate Bank, Consumer Bank, and Wealth Management, with the remainder in Other. Additional information about the Company's reportable segments is included in Regions' Annual Report on Form 10-K for the year ended December 31, 2022. The application and development of management reporting methodologies is a dynamic process and is subject to periodic enhancements. As these enhancements are made, financial results presented by each reportable segment may be periodically revised. Accordingly, the prior periods were updated to reflect these enhancements. The following tables present financial information for each reportable segment for the periods indicated: Three Months Ended September 30, 2023 Corporate Bank Consumer Wealth Other Consolidated (In millions) Net interest income $ 488 $ 760 $ 43 $ — $ 1,291 Provision for (benefit from) credit losses 87 70 2 (14) 145 Non-interest income 181 256 113 16 566 Non-interest expense 303 672 105 13 1,093 Income before income taxes 279 274 49 17 619 Income tax expense (benefit) 70 69 12 (22) 129 Net income $ 209 $ 205 $ 37 $ 39 $ 490 Average assets $ 70,032 $ 38,108 $ 2,018 $ 43,326 $ 153,484 Three Months Ended September 30, 2022 Corporate Bank Consumer Wealth Other Consolidated (In millions) Net interest income $ 510 $ 701 $ 51 $ — $ 1,262 Provision for (benefit from) credit losses 72 73 2 (12) 135 Non-interest income (loss) 210 283 108 4 605 Non-interest expense (benefit) 305 582 104 179 1,170 Income before income taxes 343 329 53 (163) 562 Income tax expense (benefit) 86 82 14 (49) 133 Net income $ 257 $ 247 $ 39 $ (114) $ 429 Average assets $ 66,384 $ 37,138 $ 2,098 $ 52,802 $ 158,422 Nine Months Ended September 30, 2023 Corporate Bank Consumer Bank Wealth Other Consolidated (In millions) Net interest income $ 1,528 $ 2,417 $ 144 $ — $ 4,089 Provision for (benefit from) credit losses 252 208 6 (68) 398 Non-interest income 525 783 339 29 1,676 Non-interest expense 928 1,947 320 36 3,231 Income before income taxes 873 1,045 157 61 2,136 Income tax expense (benefit) 219 260 39 (65) 453 Net income $ 654 $ 785 $ 118 $ 126 $ 1,683 Average assets $ 69,772 $ 37,624 $ 2,053 $ 43,999 $ 153,448 Nine Months Ended September 30, 2022 Corporate Bank Consumer Bank Wealth Other Consolidated (In millions) Net interest income $ 1,408 $ 1,849 $ 128 $ — $ 3,385 Provision for (benefit from) credit losses 208 213 7 (269) 159 Non-interest income (loss) 629 898 316 (14) 1,829 Non-interest expense (benefit) 868 1,707 302 174 3,051 Income before income taxes 961 827 135 81 2,004 Income tax expense 240 206 33 (35) 444 Net income $ 721 $ 621 $ 102 $ 116 $ 1,560 Average assets $ 63,351 $ 36,571 $ 2,123 $ 58,602 $ 160,647

Commitments and Contingencies Disclosure [Abstract]
Commitment, Contingencies and Guarantees	NOTE 11. COMMITMENTS, CONTINGENCIES AND GUARANTEES COMMERCIAL COMMITMENTS Regions issues off-balance sheet financial instruments in connection with lending activities. The credit risk associated with these instruments is essentially the same as that involved in extending loans to customers and is subject to Regions’ normal credit approval policies and procedures. Regions measures inherent risk associated with these instruments by recording a reserve for unfunded commitments based on an assessment of the likelihood that the guarantee will be funded and the creditworthiness of the customer or counterparty. Collateral is obtained based on management’s assessment of the creditworthiness of the customer. Credit risk is represented in unused commitments to extend credit, standby letters of credit and commercial letters of credit. Refer to Note 23 "Commitments, Contingencies and Guarantees" in the Annual Report on Form 10-K for the year ended December 31, 2022 for more information regarding these instruments. Credit risk associated with these instruments is represented by the contractual amounts indicated in the following table: September 30, 2023 December 31, 2022 (In millions) Unused commitments to extend credit $ 64,610 $ 65,460 Standby letters of credit 1,934 1,962 Commercial letters of credit 75 75 Liabilities associated with standby letters of credit 27 35 Assets associated with standby letters of credit 29 37 Reserve for unfunded credit commitments 130 118 LEGAL CONTINGENCIES Regions and its subsidiaries are routinely subject to actual or threatened legal proceedings, including litigation and regulatory matters, arising in the ordinary course of business. Litigation matters range from individual actions involving a single plaintiff to class action lawsuits and can involve claims for substantial or indeterminate alleged damages or for injunctive or other relief. Regulatory investigations and enforcement matters may involve formal or informal proceedings and other inquiries initiated by various governmental agencies, law enforcement authorities, and self-regulatory organizations, and can result in fines, penalties, restitution, changes to Regions’ business practices, and other related costs, including reputational damage. At any given time, these legal proceedings are at varying stages of adjudication, arbitration, or investigation, and may relate to a variety of topics, including common law tort and contract claims, as well as statutory consumer protection-related claims, among others. Assessment of exposure that could result from legal proceedings is complex because these proceedings often involve inherently unpredictable factors, including, but not limited to, the following: whether the proceeding is in early stages; whether damages or the amount of potential fines, penalties, and restitution are unspecified, unsupported, or uncertain; whether there is a potential for punitive or other pecuniary damages; whether the matter involves legal uncertainties, including novel issues of law; whether the matter involves multiple parties and/or jurisdictions; whether discovery or other investigation has begun or is not complete; whether material facts may be disputed or unsubstantiated; whether meaningful settlement discussions have commenced; and whether the matter involves class allegations. As a result of these complexities, Regions may be unable to develop an estimate or range of loss. Regions evaluates legal proceedings based on information currently available, including advice of counsel. Regions establishes accruals for those matters when a loss is considered probable and the related amount is reasonably estimable. Additionally, when it is practicable and reasonably possible that it may experience losses in excess of established accruals, Regions estimates possible loss contingencies. Regions currently estimates that the aggregate amount of reasonably possible losses that it may experience, in excess of what has been accrued, is immaterial. While the final outcomes of legal proceedings are inherently unpredictable, management is currently of the opinion that the outcomes of pending and threatened matters will not have a material effect on Regions’ business, consolidated financial position, results of operations or cash flows as a whole. As available information changes, the matters for which Regions is able to estimate, as well as the estimates themselves, will be adjusted accordingly. Regions’ estimates are subject to significant judgment and uncertainties, and the matters underlying the estimates will change from time to time. In the event of unexpected future developments, it is possible that an adverse outcome in any such matter could be material to Regions’ business, consolidated financial position, results of operations, or cash flows as a whole for any particular reporting period of occurrence. Some of Regions’ exposure with respect to loss contingencies may be offset by applicable insurance coverage. However, in determining the amounts of any accruals or estimates of possible loss contingencies, Regions does not take into account the availability of insurance coverage. To the extent that Regions has an insurance recovery, the proceeds are recorded in the period the recovery is received. GUARANTEES FANNIE MAE LOSS SHARE GUARANTEE Regions sells commercial loans to Fannie Mae through the DUS lending program and through other platforms. The DUS program provides liquidity to the multi-family housing market. Regions services loans sold to Fannie Mae and is required to provide a loss share guarantee equal to one-third of the principal balance for the majority of the commercial servicing portfolio. At September 30, 2023 and December 31, 2022, the Company's DUS servicing portfolio totaled approximately $6.2 billion and $4.9 billion, respectively. Regions has additional loans sold to Fannie Mae outside of the DUS program that are also subject to a loss share guarantee and at September 30, 2023 and December 31, 2022, these serviced loans totaled approximately $660 million and $655 million, respectively. Regions' maximum quantifiable contingent liability related to all loans subject to a loss share guarantee was approximately $2.3 billion at September 30, 2023 and $1.8 billion at December 31, 2022. The Company would be liable for this amount only if all of the loans it services for Fannie Mae, for which the Company retains some risk of loss, were to default and all of the collateral underlying these loans was determined to be without value at the time of settlement. Therefore, the maximum quantifiable contingent liability is not representative of the actual loss the Company would be expected to incur. The estimated fair value of the associated loss share guarantee recorded as a liability on the Company's consolidated balance sheets was immaterial at both September 30, 2023 and December 31, 2022. Refer to Note 1 "Summary of Significant Accounting Policies" in the Annual Report on Form 10-K for the year ended December 31, 2022 for additional information.

Accounting Standards Update and Change in Accounting Principle [Abstract]
Recent Accounting Pronouncements	NOTE 12. RECENT ACCOUNTING PRONOUNCEMENTS Standard Description Required Date of Adoption Effect on Regions' financial statements or other significant matters Standards Adopted (or partially adopted) in 2023 ASU 2022-02, Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures This Update is intended to improve the decision usefulness of information provided to investors about certain loan refinancing, restructurings, and write-offs. The amendments in the Update eliminate the accounting guidance for TDRs by creditors that have adopted CECL while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors made to borrowers experiencing financial difficulty. The Update also requires that a public business entity disclose current-period gross write-offs by year of origination for financing receivables and net investment in leases. The amendments in this Update should be applied prospectively, except for the transition method related to the recognition and measurement of TDRs for which there is an option to apply a modified retrospective transition method, resulting in a cumulative-effect adjustment to retained earnings in the period of adoption. January 1, 2023 The adoption of this guidance did not have a material impact. See Note 1 Basis of Presentation for additional information. 2022-03, Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions This Update clarifies how the fair value of equity securities subject to contractual sale restrictions is determined. ASU 2022-03 clarifies that a contractual sale restriction should not be considered in measuring fair value. It also requires entities with investments in equity securities subject to contractual sale restrictions to disclose certain qualitative and quantitative information about such securities. January 1, 2023 The adoption of this guidance did not have a material impact. 2023-03, Presentation of Financial Statements (Topic 205), Income Statement—Reporting Comprehensive Income (Topic 220), Distinguishing Liabilities from Equity (Topic 480), Equity (Topic 505), and Compensation—Stock Compensation (Topic 718) This Update amends or supersedes various SEC paragraphs within the Codification to conform to past SEC staff announcements and guidance issued by the SEC. The Update does not provide any new guidance so there is no transition guidance or effective date associated with it. Effective upon issuance The adoption of this guidance did not have a material impact. 2023-04, Liabilities (Topic 405): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 121 (SEC Update) This Update adds various SEC paragraphs to the Codification to reflect guidance included in SEC Staff Accounting Bulletin 121 on safeguarding crypto assets. The Update does not provide any new guidance so there is no transition or effective date associated with it. Effective upon issuance The adoption of this guidance did not have a material impact. Standards Not Yet Adopted ASU 2023-02, Investments —Equity Method and Joint Ventures (Topic 323) Accounting for Investments in Tax Credit Structures This Update allows entities to elect to account for equity investments made primarily for the purpose of receiving income tax credits using the proportional amortization method, regardless of the tax credit program through which the investment earns income tax credits, if certain conditions were met. The Update also sets forth the conditions needed to apply the proportional amortization method. The Update further eliminates certain low income housing tax credit-specific guidance to align the accounting more closely for low income housing tax credits with the accounting for other equity investments in tax credit structures and require that the delayed equity contribution apply only to tax equity investments accounted for using the proportional amortization method. January 1, 2024 The adoption of this guidance is not likely to have a material impact. Regions will continue to evaluate through date of adoption. 2023-05, Business Combinations— This Update requires certain joint ventures, upon formation, to use a new basis of accounting by applying most aspects of the acquisition method for business combinations. New joint ventures generally will recognize and initially measure assets and liabilities at fair value. The Update is effective for all joint ventures with a formation date on or after January 1, 2025. Early adoption is permitted.

Accounting Policies [Abstract]
Financing Receivable, Allowance for Credit Losses, Policy or Methodology Change	MODIFICATIONS TO BORROWERS EXPERIENCING FINANCIAL DIFFICULTY On January 1, 2023, the Company adopted new accounting guidance that eliminated the recognition and measurement guidance for TDRs while enhancing disclosure requirements for certain loan refinancings and restructurings made to borrowers experiencing financial difficulty, also referred to as modifications to troubled borrowers. The guidance also requires disclosure of current-period gross write-offs by year of origination. Regions applied the guidance prospectively, except Regions used the modified-retrospective transition method related to the recognition and measurement of TDRs. The cumulative effect of the modified-retrospective application was a decrease in the allowance of $38 million and an increase to retained earnings of $28 million, net of taxes. Refer to Note 1 "Summary of Significant Accounting Policies" and Note 5 "Allowance for Credit Losses" in the Annual Report on Form 10-K for the year ended December 31, 2022 for additional information regarding TDRs and the related allowance for credit loss accounting prior to the adoption of modifications to troubled borrowers guidance. Modifications to troubled borrowers Modifications to troubled borrowers are loans where the borrower is experiencing financial difficulty at the time of modification and are undertaken in order to improve the likelihood of repayment. Modification types classified as modifications to troubled borrowers include interest rate reductions, other than insignificant term extensions, other than insignificant payment deferrals, principal forgiveness, or any combination of these. Further details are as follows: • Interest rate reduction modifications include instances where the absolute interest rate is reduced as part of the modification. In instances where the rate index changes for variable-rate loans, Regions evaluates whether or not the absolute interest rate decreases from the original rate to the updated rate. • Term extensions are maturity extensions, many of which occur through renewals or restructurings. • Payment deferrals include modifications wherein the contractual payment term is extended. Examples of payment deferral modifications include, but are not limited to, re-agings, payment delays or holidays, lengthening of amortization terms, allowing for an interest-only payment period, and capitalizing interest payments in loan restructurings. • Regions rarely grants principal forgiveness modifications. Modifications to troubled borrowers are subject to policies governing accrual/non-accrual evaluation consistent with all other loans of the same product type as discussed in Note 1 "Summary of Significant Accounting Policies" in the Annual Report on Form 10-K for the year ended December 31, 2022. As such, modifications to troubled borrowers may include loans remaining on non-accrual, moving to non-accrual, or continuing on accrual status, depending on the individual facts and circumstances. Allowance for credit losses The allowance is intended to cover expected credit losses over the contractual life of loans measured at amortized cost, including unfunded commitments. Upon the adoption of modifications to troubled borrowers guidance in January 2023, the Company eliminated TDR and reasonable expectations of a TDR ("RETDR") designations and specific measurement rules within the calculation of the allowance credit losses, which resulted in a decrease to the allowance upon application of the modified-retrospective transition method discussed above. See Note 1 "Summary of Significant Accounting Policies" in the Annual Report on Form 10-K for the year ended December 31, 2022 for previous discussion of allowance measurement methodology for these items. Modifications identified as modifications to troubled borrowers have no separate or distinct allowance measurement rules under the new guidance. As such, these loans are included in their respective loan pools (if they do not qualify for specific evaluation) and expected losses are determined by the Company's allowance models and qualitative framework.

Schedule Of Carrying Amounts And Estimated Fair Values Of Financial Instruments	The carrying amounts and estimated fair values, as well as the level within the fair value hierarchy, of the Company’s financial instruments as of September 30, 2023 are as follows: September 30, 2023 Carrying Estimated Fair Value (1) Level 1 Level 2 Level 3 (In millions) Financial assets: Cash and cash equivalents $ 9,016 $ 9,016 $ 9,016 $ — $ — Debt securities held to maturity 763 703 — 703 — Debt securities available for sale 26,228 26,228 1,186 25,041 1 Loans held for sale 459 459 — 397 62 Loans (excluding leases), net of unearned income and allowance for loan losses (2)(3) 95,753 90,849 — — 90,849 Other earning assets 1,552 1,552 745 807 — Derivative assets 2,979 2,979 — 2,971 8 Financial liabilities: Derivative liabilities 4,226 4,226 11 4,214 1 Deposits with no stated maturity (4) 113,006 113,006 — 113,006 — Time deposits (4) 13,193 13,095 — 13,095 — Short-term borrowings 2,000 2,000 — 2,000 — Long-term borrowings 4,290 4,256 — 4,255 1 Loan commitments and letters of credit 157 157 — — 157 _________ (1) Estimated fair values are consistent with an exit price concept. The assumptions used to estimate the fair values are intended to approximate those that a market participant would use in a hypothetical orderly transaction. In estimating fair value, the Company makes adjustments for estimated changes in interest rates, market liquidity and credit spreads in the periods they are deemed to have occurred. (2) The estimated fair value of portfolio loans assumes sale of the loans to a third-party financial investor. Accordingly, the value to the Company if the loans were held to maturity is not reflected in the fair value estimate. The fair value discount on the loan portfolio's net carrying amount at September 30, 2023 was $4.9 billion or 5.1 percent. (3) Excluded from this table is the sales-type, direct financing, and leveraged lease carrying amount of $1.6 billion at September 30, 2023. (4) The fair value of non-interest-bearing demand accounts, interest-bearing checking accounts, savings accounts, and money market accounts is the amount payable on demand at the reporting date (i.e., the carrying amount) as these instruments have an indeterminate maturity date. Fair values for time deposits are estimated by using discounted cash flow analyses, based on market spreads to benchmark rates. The carrying amounts and estimated fair values, as well as the level within the fair value hierarchy, of the Company's financial instruments as of December 31, 2022 are as follows: December 31, 2022 Carrying Estimated Fair Value (1) Level 1 Level 2 Level 3 (In millions) Financial assets: Cash and cash equivalents $ 11,227 $ 11,227 $ 11,227 $ — $ — Debt securities held to maturity 801 751 — 751 — Debt securities available for sale 27,933 27,933 1,187 26,744 2 Loans held for sale 354 354 — 335 19 Loans (excluding leases), net of unearned income and allowance for loan losses (2)(3) 94,044 89,540 — — 89,540 Other earning assets 1,308 1,308 529 779 — Derivative assets 2,609 2,609 3 2,603 3 Financial liabilities: Derivative liabilities 3,378 3,378 2 3,375 1 Deposits with no stated maturity (4) 125,971 125,971 — 125,971 — Time deposits (4) 5,772 5,697 — 5,697 — Long-term borrowings 2,284 2,376 — 2,375 1 Loan commitments and letters of credit 153 153 — — 153 _________ (1) Estimated fair values are consistent with an exit price concept. The assumptions used to estimate the fair values are intended to approximate those that a market participant would use in a hypothetical orderly transaction. In estimating fair value, the Company makes adjustments for estimated changes in interest rates, market liquidity and credit spreads in the periods they are deemed to have occurred. (2) The estimated fair value of portfolio loans assumes sale of the loans to a third-party financial investor. Accordingly, the value to the Company if the loans were held to maturity is not reflected in the fair value estimate. The fair value discount on the loan portfolio's net carrying amount at December 31, 2022 was $4.5 billion or 4.8 percent. (3) Excluded from this table is the sales-type, direct financing, and leveraged lease carrying amount of $1.5 billion at December 31, 2022. (4) The fair value of non-interest-bearing demand accounts, interest-bearing checking accounts, savings accounts, and money market accounts is the amount payable on demand at the reporting date (i.e., the carrying amount) as these instruments have an indeterminate maturity date. Fair values for time deposits are estimated by using discounted cash flow analyses, based on market spreads to benchmark rates.
