New accounting guidance	New accounting guidanceThe following accounting guidance was adopted in the first quarter of 2023. Accounting Standards Update (“ASU”) 2022-01, Derivatives and Hedging (Topic 815): Fair Value Hedging – Portfolio Layer Method In March 2022, the FASB issued ASU 2022-01, Derivatives and Hedging (Topic 815): Fair Value Hedging – Portfolio Layer Method , which provides guidance that expands the ability to hedge interest rate risk by permitting the use of multiple hedged layers of a single closed portfolio of assets and will (1) Allow multiple layer hedging within the same closed portfolio, (2) Expand the scope of the portfolio layer method to include non-prepayable assets, (3) Expand the eligible hedging instruments to be utilized in a single-layer hedge, and (4) Permit held-to-maturity debt securities to be transferred to available-for-sale at the date of adoption, provided such transferred securities are designated in a portfolio layer method hedge within 30 days of the adoption date. The standard also provides further guidance and disclosure requirements with respect to hedge basis adjustments related to portfolio layer method hedges. We adopted this guidance as of Jan. 1, 2023. The Company did not choose to make the one-time election to reclassify securities classified as held-to-maturity to available-for-sale as of Jan. 1, 2023 and can choose to prospectively apply portfolio layer method hedging. ASU 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures In March 2022, the FASB issued ASU 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures , which provides post-implementation guidance related to the adoption of ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments , which was effective Jan. 1, 2020. This ASU amends the guidance related to two issues: Troubled Debt Restructurings (“TDRs”) and disclosure requirements for the credit profile of the loan portfolio. This ASU eliminates the accounting guidance for TDRs by creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. An entity must apply the loan refinancing and restructuring guidance to determine whether a modification results in a new loan or a continuation of an existing loan. This ASU also requires that an entity disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20, Financial Instruments – Credit Losses – Measured at Amortized Cost .

Acquisitions and dispositions	Acquisitions and dispositions We sometimes structure our acquisitions and divestitures with both an initial payment or receipt and later contingent payments or receipts tied to post-closing revenue or income growth. Contingent payments totaled $5 million in the first six months of 2023. There were no contingent receipts in the first six months of 2023. At June 30, 2023, we are potentially obligated to pay additional consideration which, using reasonable assumptions and estimates, could range from $25 million to $40 million over the next two years . At June 30, 2023, we could potentially receive additional consideration which, using reasonable assumptions and estimates, could be up to $390 million over the next five years .

The allowance for credit loss primarily relates to non-agency RMBS. (b) Includes gross unrealized gains of $347 million and gross unrealized losses of $179 million recorded in accumulated other comprehensive income related to securities that were transferred from available-for-sale to held-to-maturity. The unrealized gains primarily relate to agency RMBS, U.S. Treasury securities and agency commercial MBS. The unrealized losses primarily relate to agency RMBS and U.S. Treasury securities. The unrealized gains and losses will be amortized into net interest revenue over the contractual lives of the securities. The following table presents the realized gains and losses, on a gross basis.

Credit quality indicators – Securities At June 30, 2023, the gross unrealized losses on the securities portfolio were primarily attributable to an increase in interest rates from the date of purchase, and for certain securities that were transferred from available-for-sale to held-to-maturity, an increase in interest rates through the date they were transferred. Specifically, $162 million of the unrealized losses at June 30, 2023 and $179 million at Dec. 31, 2022 reflected in the tables below relate to certain securities that were previously transferred from available-for-sale to held-to-maturity. The unrealized losses will be amortized into net interest revenue over the contractual lives of the securities. The transfer created a new cost basis for the securities. As a result, if these securities have experienced unrealized losses since the date of transfer, the corresponding unrealized losses would be reflected in the held-to-maturity securities portfolio in the following tables. We do not intend to sell these securities, and it is not more likely than not that we will have to sell these securities. The following tables show the aggregate fair value of available-for-sale securities with a continuous unrealized loss position for less than 12 months and those that have been in a continuous unrealized loss position for 12 months or more without an allowance for credit losses.

The following tables show the credit quality of the held-to-maturity securities. We have included certain credit ratings information because the information can indicate the degree of credit risk to which we are exposed. Significant changes in ratings classifications could indicate increased credit risk for us and could be accompanied by an increase in the allowance for credit losses and/or a reduction in the fair value of our securities portfolio.

Pledged assets At June 30, 2023, BNY Mellon had pledged assets of $133 billion, including $93 billion pledged as collateral for potential borrowings at the Federal Reserve Discount Window and $8 billion pledged as collateral for borrowing at the Federal Home Loan Bank. The components of the assets pledged at June 30, 2023 included $114 billion of securities, $13 billion of loans, $5 billion of trading assets and $1 billion of interest-bearing deposits with banks. If there has been no borrowing at the Federal Reserve Discount Window, the Federal Reserve generally allows banks to freely move assets in and out of their pledged assets account to sell or repledge the assets for other purposes. BNY Mellon regularly moves assets in and out of its pledged assets account at the Federal Reserve as there has been no borrowings. At Dec. 31, 2022, BNY Mellon had pledged assets of $138 billion, including $106 billion pledged as collateral for potential borrowing at the Federal Reserve Discount Window and $8 billion pledged as collateral for borrowing at the Federal Home Loan Bank. The components of the assets pledged at Dec. 31, 2022 included $121 billion of securities, $12 billion of loans, $4 billion of trading assets and $1 billion of interest-bearing deposits with banks. At June 30, 2023 and Dec. 31, 2022, pledged assets included $30 billion and $24 billion, respectively, for which the recipients were permitted to sell or repledge the assets delivered. We also obtain securities as collateral, including receipts under resale agreements, securities borrowed, derivative contracts and custody agreements, on terms which permit us to sell or repledge the securities to others. At June 30, 2023 and Dec. 31, 2022, the market value of the securities received that can be sold or repledged was $199 billion and $115 billion, respectively. We routinely sell or repledge these securities through delivery to third parties. As of June 30, 2023 and Dec. 31, 2022, the market value of securities collateral sold or repledged was $161 billion and $78 billion, respectively. Restricted cash and securities Cash and securities may be segregated under federal and other regulations or requirements. At June 30, 2023 and Dec. 31, 2022, cash segregated under federal and other regulations or requirements was $4 billion and $7 billion, respectively. Restricted cash is primarily included in interest-bearing deposits with banks on the consolidated balance sheet. Securities segregated under federal and other regulations or requirements were $4 billion at June 30, 2023 and $3 billion at Dec. 31, 2022.

The modification could result in a new loan or a continuation of the existing loan. In the second quarter of 2023, we modified one commercial real estate exposure, with a recorded investment of $59 million and an unfunded lending commitment of $15 million, by extending the maturity date. We also modified two other residential mortgage loans, with an aggregate recorded investment of less than $1 million, by extending the maturity dates and reducing the interest rates. We modified one commercial real estate loan in the first quarter of 2023, with a recorded investment of $12 million, by extending the maturity date. Loans modified prior to 2023 are considered a troubled debt restructuring (“TDR”) if the debtor is experiencing financial difficulties and the creditor Credit quality indicators Our credit strategy is to focus on investment-grade clients that are active users of our non-credit services. Each customer is assigned an internal credit rating, which is mapped to an external rating agency grade equivalent, if possible, based upon a number of dimensions, which are continually evaluated and may change over time. The tables below provide information about the credit profile of the loan portfolio by the period of origination.

Overdrafts occur on a daily basis primarily in the custody and securities clearance business and are generally repaid within two Commercial loans The commercial loan portfolio is divided into investment grade and non-investment grade categories based on the assigned internal credit ratings, which are generally consistent with those of the public rating agencies. Customers with ratings consistent with BBB- (S&P)/Baa3 (Moody’s) or better are considered to be investment grade. Those clients with ratings lower than this threshold are considered to be non-investment grade. Commercial real estate Our income-producing commercial real estate facilities are focused on experienced owners and are structured with moderate leverage based on existing cash flows. Our commercial real estate lending activities also include construction and renovation facilities. Financial institutions Financial institution exposures are high quality, with 94% of the exposures meeting the investment grade equivalent criteria of our internal credit rating classification at June 30, 2023. In addition, 65% of the financial institutions exposure is secured. For example, securities industry clients and asset managers often borrow against marketable securities held in custody. The exposure to financial institutions is generally short term, with 84% expiring within one year. Wealth management loans Wealth management loans are not typically rated by external rating agencies. A majority of the wealth management loans are secured by the customers’ investment management accounts or custody accounts. Eligible assets pledged for these loans are typically investment grade fixed-income securities, equities and/or mutual funds. Internal ratings for this portion of the wealth management loan portfolio, therefore, would equate to investment grade external ratings. Wealth management loans are provided to select customers based on the pledge of other types of assets. For the loans collateralized by other assets, the credit quality of the obligor is carefully analyzed, but we do not consider this portion of our wealth management loan portfolio to be investment grade. Wealth management mortgages Credit quality indicators for wealth management mortgages are not correlated to external ratings. Wealth management mortgages are typically loans to high-net-worth individuals, which are secured primarily by residential property. These loans are primarily interest-only, adjustable-rate mortgages with a weighted-average loan-to-value ratio of 61% at origination. Delinquency rate is a key indicator of credit quality in our wealth management portfolio. At June 30, 2023, less than 1% of the mortgages were past due. At June 30, 2023, the wealth management mortgage portfolio consisted of the following geographic concentrations: California – 21%; New York – 15%; Florida – 11%; Massachusetts – 8%; and other – 45%. Lease financings At June 30, 2023, the lease financings portfolio consisted of exposures backed by well-diversified assets, primarily real estate and large-ticket transportation equipment. The largest components of our lease residual value exposure relate to freight-related rail cars and aircraft. Assets are both domestic and foreign-based, with primary concentrations in Germany and the U.S. Other residential mortgages The other residential mortgages portfolio primarily consists of 1-4 family residential mortgage loans and totaled $1.0 billion at June 30, 2023 and $345 million at Dec. 31, 2022. Included in this portfolio at June 30, 2023 were $760 million of fixed-rate jumbo mortgage loans, purchased primarily in the first quarter of 2023, with a weighted-average loan-to-value ratio of 73% at origination. These loans are not typically correlated to external ratings. Capital call financing Capital call financing includes loans to private equity funds that are secured by the fund investors’ capital commitments and the funds’ right to call capital. Other loans Other loans primarily include loans to consumers that are fully collateralized with equities, mutual funds and fixed-income securities. Margin loans We had $15.6 billion of secured margin loans at June 30, 2023, compared with $16.9 billion at Dec. 31, 2022. Margin loans are collateralized with marketable securities, and borrowers are required to maintain a daily collateral margin in excess of 100% of the value of the loan. We have rarely suffered a loss on these types of loans. Overdrafts Overdrafts primarily relate to custody and securities clearance clients and totaled $2.7 billion at June 30, 2023 and $4.8 billion at Dec. 31, 2022. Overdrafts occur on a daily basis and are generally repaid within two Reverse repurchase agreements

An interim test is performed when events or circumstances occur that may indicate that it is more likely than not that the fair value of any reporting unit may be less than its carrying value. In the second quarter of 2023, due to the results of the first quarter 2023 interim and annual impairment test and macroeconomic conditions, we performed an interim goodwill impairment test of the Investment Management reporting unit, which had $6.1 billion of allocated goodwill. No additional goodwill impairment was recognized. In the second quarter of 2023, we also performed our annual goodwill impairment test on the remaining five reporting units. As a result of the annual goodwill impairment test, no goodwill impairment was recognized. Intangible assets The tables below provide a breakdown of intangible assets by business segment.

See Note 10 of the Notes to Consolidated Financial Statements in our 2022 Annual Report for information on the nature of our services and revenue recognition. See Note 24 of the Notes to Consolidated Financial Statements in our 2022 Annual Report for additional information on our principal business segments — Securities Services, Market and Wealth Services and Investment and Wealth Management — and the primary services provided. Disaggregation of contract revenue Contract revenue is included in fee and other revenue on the consolidated income statement. The following tables present fee and other revenue related to contracts with customers, disaggregated by type of fee revenue, for each business segment. Business segment data has been determined on an internal management basis of accounting, rather than GAAP, which is used for consolidated financial reporting.

Contract balances Our clients are billed based on fee schedules that are agreed upon in each customer contract. Receivables from customers were $2.7 billion at June 30, 2023 and $2.6 billion at Dec. 31, 2022. Contract assets represent accrued revenues that have not yet been billed to customers due to certain contractual terms other than the passage of time and were $70 million at June 30, 2023 and $48 million at Dec. 31, 2022. Accrued revenues recorded as contract assets are usually billed on an annual basis. Both receivables from customers and contract assets are included in other assets on the consolidated balance sheet. Contract liabilities represent payments received in advance of providing services under certain contracts and were $217 million at June 30, 2023 and $164 million at Dec. 31, 2022. Contract liabilities are included in other liabilities on the consolidated balance sheet. Revenue recognized in the first six months of 2023 relating to contract liabilities as of Dec. 31, 2022 was $84 million. Revenue recognized in the second quarter of 2023 relating to contract liabilities as of March 31, 2023 was $66 million. Changes in contract assets and liabilities primarily relate to either party’s performance under the contracts. Contract costs Incremental costs for obtaining contracts that are deemed recoverable are capitalized as contract costs. Such costs result from the payment of sales incentives, primarily in the Wealth Management business, and totaled $53 million at June 30, 2023 and $58 million at Dec. 31, 2022. Capitalized sales incentives are amortized based on the transfer of goods or services to which the assets relate. The amortization of capitalized sales incentives, which is included in staff expense on the consolidated income statement, totaled $4 million in the second quarter of 2023, second quarter of 2022 and first quarter of 2023, $8 million in the first six months of 2023 and $9 million in the first six months of 2022. Costs to fulfill a contract are capitalized when they relate directly to an existing contract or a specific anticipated contract, generate or enhance resources that will be used to fulfill performance obligations, and are recoverable. Such costs generally represent set-up costs, which include any direct cost incurred at the inception of a contract which enables the fulfillment of the performance obligation, and totaled $85 million at June 30, 2023 and $77 million at Dec. 31, 2022. These capitalized costs are amortized on a straight-line basis over the expected contract period. Unsatisfied performance obligations We do not have any unsatisfied performance obligations other than those that are subject to a practical expedient election under ASC 606, Revenue From Contracts With Customers . The practical expedient election applies to (i) contracts with an original expected length of one year or less, and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed.

Income Tax Disclosure [Abstract]
Income taxes	Income taxes BNY Mellon recorded an income tax provision of $270 million (20.2% effective tax rate) in the second quarter of 2023, $231 million (21.1% effective tax rate) in the second quarter of 2022 and $260 million (21.0% effective tax rate) in the first quarter of 2023. Our total tax reserves as of June 30, 2023 were $107 million, compared with $106 million at Dec. 31, 2022. If these tax reserves were unnecessary, $107 million would affect the effective tax rate in future periods. We recognize accrued interest and penalties, if applicable, related to income taxes in income tax expense. Included in the balance sheet at June 30, 2023 is accrued interest, where applicable, of $34 million. The additional tax expense related to interest for the six months ended June 30, 2023 was $1 million, compared with $4 million for the six months ended June 30, 2022. It is reasonably possible the total reserve for uncertain tax positions could decrease within the next 12 months by approximately $10 million as a result of adjustments related to tax years that are still subject to examination.

Securitizations And Variable Interest Entities Disclosure [Abstract]
Variable interest entities	Variable interest entities We have variable interests in variable interest entities (“VIEs”), which include investments in retail, institutional and alternative investment funds. We earn management fees from these funds, as well as performance fees in certain funds, and may also provide start-up capital for new funds. The funds are primarily financed by our customers’ investments in the funds’ equity or debt. Additionally, we invest in qualified affordable housing and renewable energy projects, which are designed to generate a return primarily through the realization of tax credits. The projects, which are structured as limited partnerships and limited liability companies, are also VIEs, but are not consolidated. The following table presents the incremental assets and liabilities included on the consolidated balance sheet as of June 30, 2023 and Dec. 31, 2022. The net assets of any consolidated VIE are solely available to settle the liabilities of the VIE and to settle any investors’ ownership liquidation requests, including any seed capital we invested in the VIE.

Fair Value Disclosures [Abstract]
Fair value measurement	Fair value measurementFair value is defined as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date. A three-level hierarchy for fair value measurements is utilized based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. BNY Mellon’s own creditworthiness is considered when valuing liabilities. See Note 20 of the Notes to Consolidated Financial Statements in our 2022 Annual Report for information on how we determine fair value and the fair value hierarchy. The following tables present the financial instruments carried at fair value at June 30, 2023 and Dec. 31, 2022, by caption on the consolidated balance sheet and by the three-level valuation hierarchy.

Fair Value Disclosures [Abstract]
Fair value option	Fair value option We elected fair value as an alternative measurement for selected financial assets and liabilities that are not otherwise required to be measured at fair value, including the assets and liabilities of consolidated investment management funds and subordinated notes associated with certain equity investments. The following table presents the assets and liabilities of consolidated investment management funds, at fair value. Assets and liabilities of consolidated investment management funds, at fair value June 30, 2023 Dec. 31, 2022 (in millions) Assets of consolidated investment management funds: Trading assets $ 484 $ 203 Other assets 15 6 Total assets of consolidated investment management funds $ 499 $ 209 Liabilities of consolidated investment management funds: Other liabilities $ 8 $ 1 Total liabilities of consolidated investment management funds $ 8 $ 1 The assets and liabilities of the consolidated investment management funds are included in other assets and other liabilities on the consolidated balance sheet. We value the assets and liabilities of consolidated investment management funds using quoted prices for identical assets or liabilities in active markets or observable inputs such as quoted prices for similar assets or liabilities. Quoted prices for either identical or similar assets or liabilities in inactive markets may also be used. Accordingly, fair value best reflects the interests BNY Mellon holds in the economic performance of the consolidated investment management funds. Changes in the fair value of the assets and liabilities are recorded as income (loss) from consolidated investment management funds, which is included in investment and other revenue on the consolidated income statement. We elected the fair value option on subordinated notes associated with certain equity investments. The fair value of these subordinated notes was $8 million at June 30, 2023 and $10 million at Dec. 31, 2022. The subordinated notes were valued using observable market inputs and included in Level 2 of the valuation hierarchy.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative instruments	Derivative instruments We use derivatives to manage exposure to market risk, including interest rate risk, equity price risk and foreign currency risk, as well as credit risk. Our trading activities are focused on acting as a market-maker for our customers and facilitating customer trades in compliance with the Volcker Rule. The notional amounts for derivative financial instruments express the dollar volume of the transactions; however, credit risk is much smaller. We perform credit reviews and enter into netting agreements and collateral arrangements to minimize the credit risk of derivative financial instruments. We enter into offsetting positions to reduce exposure to foreign currency, interest rate and equity price risk. Use of derivative financial instruments involves reliance on counterparties. Failure of a counterparty to honor its obligation under a derivative contract is a risk we assume whenever we engage in a derivative contract. There were no counterparty default losses recorded in the second quarter of 2023. Hedging derivatives We utilize interest rate swap agreements to manage our exposure to interest rate fluctuations. We enter into fair value hedges as an interest rate risk management strategy to reduce fair value variability by converting certain fixed rate interest payments associated with available-for-sale securities and long-term debt to floating interest rates. We also utilize interest rate swaps and forward exchange contracts as cash flow hedges to manage our exposure to interest rate and foreign exchange rate changes. The available-for-sale securities hedged consist of U.S. Treasury, agency and non-agency commercial MBS, sovereign debt/sovereign guaranteed and foreign covered bonds. At June 30, 2023, $29.4 billion par value of available-for-sale securities were hedged with interest rate swaps designated as fair value hedges that had notional values of $29.7 billion. The fixed rate long-term debt instruments hedged generally have original maturities of five In addition, we utilize forward foreign exchange contracts as hedges to mitigate foreign exchange exposures. We use forward foreign exchange contracts as cash flow hedges to convert certain forecasted non-U.S. dollar revenue and expenses into U.S. dollars. We use forward foreign exchange contracts with maturities of 15 months or less as cash flow hedges to hedge our foreign exchange exposure to currencies such as the Indian rupee, Polish zloty, Hong Kong dollar, Singapore dollar, British pound and euro used in revenue and expense transactions for entities that have the U.S. dollar as their functional currency. As of June 30, 2023, the hedged forecasted foreign currency transactions and designated forward foreign exchange contract hedges were $589 million (notional), with a net pre-tax gain of $5 million recorded in accumulated other comprehensive income (“OCI”). This gain will be reclassified to earnings over the next 12 months. In 2022, we utilized forward foreign exchange contracts as fair value hedges of the foreign exchange risk associated with available-for-sale securities. At June 30, 2023, there were no remaining foreign exchange contracts. Forward points are designated as an excluded component and amortized into earnings over the hedge period. Forward foreign exchange contracts are also used to hedge the value of our net investments in foreign subsidiaries. These forward foreign exchange contracts have maturities of less than one year. The derivatives employed are designated as hedges of changes in value of our foreign investments due to exchange rates. The change in fair market value of these forward foreign exchange contracts is reported within foreign currency translation adjustments in shareholders’ equity, net of tax. At June 30, 2023, forward foreign exchange contracts with notional amounts totaling $10.3 billion were designated as net investment hedges. From time to time, we also designate non-derivative financial instruments as hedges of our net investments in foreign subsidiaries. At June 30, 2023, there were no non-derivative financial instruments hedging our net investments in foreign subsidiaries.

(b) For derivative transactions settled at clearing organizations, cash collateral exchanged is deemed a settlement of the derivative each day. The settlement reduces the gross fair value of derivative assets and liabilities and results in a corresponding decrease in the effect of master netting agreements, with no impact to the consolidated balance sheet. (c) The fair value of asset derivatives and liability derivatives not designated as hedging instruments is recorded as trading assets and trading liabilities, respectively, on the consolidated balance sheet. (d) Fair values are on a gross basis, before consideration of master netting agreements, as required by ASC 815, Derivatives and Hedging. (e) Effect of master netting agreements includes cash collateral received and paid of $1,468 million and $1,104 million, respectively, at June 30, 2023, and $1,786 million and $1,823 million, respectively, at Dec. 31, 2022. Trading activities (including trading derivatives) Our trading activities are focused on acting as a market-maker for our customers, facilitating customer trades and risk-mitigating economic hedging in compliance with the Volcker Rule. The change in the fair value of the derivatives utilized in our trading activities is recorded in foreign exchange revenue and investment and other revenue on the consolidated income statement. The following table presents our foreign exchange revenue and other trading revenue. Foreign exchange revenue and other trading revenue (in millions) 2Q23 1Q23 2Q22 YTD23 YTD22 Foreign exchange revenue $ 158 $ 176 $ 222 $ 334 $ 429 Other trading revenue 53 45 45 98 50 Foreign exchange revenue includes income from purchasing and selling foreign currencies, currency forwards, futures and options as well as foreign currency remeasurement. Other trading revenue reflects results from trading in cash instruments, including fixed income and equity securities, and trading and economic hedging activity with non-foreign exchange derivatives. We also use derivative financial instruments as risk-mitigating economic hedges, which are not formally designated as accounting hedges. This includes hedging the foreign currency, interest rate or market risks inherent in some of our balance sheet exposures, such as seed capital investments and deposits, as well as certain investment management fee revenue streams. We also use total return swaps to economically hedge obligations arising from the Company’s deferred compensation plan whereby the participants defer compensation and earn a return linked to the performance of investments they select. The gains or losses on these total return swaps are recorded in staff expense on the consolidated income statement and were a gain of $8 million in the second quarter of 2023, a loss of $30 million in the second quarter of 2022, gains of $7 million in the first quarter of 2023 and $15 million in the first six months of 2023 and a loss of $43 million in the first six months of 2022. We manage trading risk through a system of position limits, a value-at-risk (“VaR”) methodology based on historical simulation and other market sensitivity measures. Risk is monitored and reported to senior management by a separate unit, independent from trading, on a daily basis. Based on certain assumptions, the VaR methodology is designed to capture the potential overnight pre-tax dollar loss from adverse changes in fair values of all trading positions. The calculation assumes a one VaR methodology does not evaluate risk attributable to extraordinary financial, economic or other occurrences. As a result, the risk assessment process includes a number of stress scenarios based upon the risk factors in the portfolio and management’s assessment of market conditions. Additional stress scenarios based upon historical market events are also performed. Stress tests may incorporate the impact of reduced market liquidity and the breakdown of historically observed correlations and extreme scenarios. VaR and other statistical measures, stress testing and sensitivity analysis are incorporated into other risk management materials. Counterparty credit risk and collateral We assess the credit risk of our counterparties through regular examination of their financial statements, confidential communication with the management of those counterparties and regular monitoring of publicly available credit rating information. This and other information is used to develop proprietary credit rating metrics used to assess credit quality. Collateral requirements are determined after a comprehensive review of the credit quality of each counterparty. Collateral is generally held or pledged in the form of cash and/or highly liquid government securities. Collateral requirements are monitored and adjusted daily. Additional disclosures concerning derivative financial instruments are provided in Note 15. Disclosure of contingent features in over-the-counter (“OTC”) derivative instruments Certain OTC derivative contracts and/or collateral agreements contain credit risk-contingent features triggered upon a rating downgrade in which the counterparty has the right to request additional collateral or the right to terminate the contracts in a net liability position. The following table shows the aggregate fair value of OTC derivative contracts in net liability positions that contained credit risk-contingent features and the value of collateral that has been posted. June 30, 2023 Dec. 31, 2022 (in millions) Aggregate fair value of OTC derivatives in net liability positions (a) $ 2,006 $ 3,069 Collateral posted $ 2,680 $ 3,484 (a) Before consideration of cash collateral. The aggregate fair value of OTC derivative contracts containing credit risk-contingent features can fluctuate from quarter to quarter due to changes in market conditions, composition of counterparty trades, new business or changes to the contingent features. The Bank of New York Mellon, our largest banking subsidiary, enters into the substantial majority of our OTC derivative contracts and/or collateral agreements. As such, the contingent features may be triggered if The Bank of New York Mellon’s long-term issuer rating were downgraded. The following table shows the fair value of contracts falling under early termination provisions that were in net liability positions for three key ratings triggers. Potential close-out exposures (fair value) (a) June 30, 2023 Dec. 31, 2022 (in millions) If The Bank of New York Mellon’s rating changed to: (b) A3/A- $ 162 $ 20 Baa2/BBB $ 792 $ 545 Ba1/BB+ $ 1,411 $ 1,803 (a) The amounts represent potential total close-out values if The Bank of New York Mellon’s long-term issuer rating were to immediately drop to the indicated levels, and do not reflect collateral posted. (b) Represents ratings by Moody’s/S&P. Offsetting assets and liabilities The following tables present derivative and financial instruments and their related offsets.

Commitments and Contingencies Disclosure [Abstract]
Commitments and contingent liabilities	Commitments and contingent liabilities Off-balance sheet arrangements In the normal course of business, various commitments and contingent liabilities are outstanding that are not reflected in the accompanying consolidated balance sheets. Our significant trading and off-balance sheet risks are securities, foreign currency and interest rate risk management products, commercial lending commitments, letters of credit and securities lending indemnifications. We assume these risks to reduce interest rate and foreign currency risks, to provide customers with the ability to meet credit and liquidity needs and to hedge foreign currency and interest rate risks. These items involve, to varying degrees, credit, foreign currency and interest rate risks not recognized on the balance sheet. Our off-balance sheet risks are managed and monitored in manners similar to those used for on-balance sheet risks. The following table presents a summary of our off-balance sheet credit risks. Off-balance sheet credit risks June 30, 2023 Dec. 31, 2022 (in millions) Lending commitments $ 49,485 $ 49,750 Standby letters of credit (“SBLC”) (a) 1,945 1,918 Commercial letters of credit 46 19 Securities lending indemnifications (b)(c) 457,772 491,043 (a) Net of participations totaling $185 million at June 30, 2023 and $175 million at Dec. 31, 2022. (b) Excludes the indemnification for securities for which BNY Mellon acts as an agent on behalf of CIBC Mellon clients, which totaled $63 billion at June 30, 2023 and $64 billion at Dec. 31, 2022. (c) Includes cash collateral, invested in indemnified repurchase agreements, held by us as securities lending agent of $44 billion at June 30, 2023 and $43 billion at Dec. 31, 2022. The total potential loss on undrawn lending commitments, standby and commercial letters of credit and securities lending indemnifications is equal to the total notional amount if drawn upon, which does not consider the value of any collateral. Since many of the lending commitments are expected to expire without being drawn upon, the total amount does not necessarily represent future cash requirements. A summary of lending commitment maturities is as follows: $29.5 billion in less than one year, $19.8 billion in one to five years and $253 million over five years. SBLCs principally support obligations of corporate clients and were collateralized with cash and securities of $145 million at June 30, 2023 and $144 million at Dec. 31, 2022. At June 30, 2023, $1.4 billion of the SBLCs will expire within one year, $537 million in one to five years and $8 million over five years. We must recognize, at the inception of an SBLC and foreign and other guarantees, a liability for the fair value of the obligation undertaken in issuing the guarantee. The fair value of the liability, which was recorded with a corresponding asset in other assets, was estimated as the present value of contractual customer fees. The estimated liability for losses related to SBLCs and foreign and other guarantees, if any, is included in the allowance for lending-related commitments. Payment/performance risk of SBLCs is monitored using both historical performance and internal ratings criteria. BNY Mellon’s historical experience is that SBLCs typically expire without being funded. SBLCs below investment grade are monitored closely for payment/performance risk. The table below shows SBLCs by investment grade: Standby letters of credit June 30, 2023 Dec. 31, 2022 Investment grade 76 % 75 % Non-investment grade 24 % 25 % A commercial letter of credit is normally a short-term instrument used to finance a commercial contract for the shipment of goods from a seller to a buyer. Although the commercial letter of credit is contingent upon the satisfaction of specified conditions, it represents a credit exposure if the buyer defaults on the underlying transaction. As a result, the total contractual amounts do not necessarily represent future cash requirements. Commercial letters of credit totaled $46 million at June 30, 2023 and $19 million at Dec. 31, 2022. We expect many of the lending commitments and letters of credit to expire without the need to advance any cash. The revenue associated with guarantees frequently depends on the credit rating of the obligor and the structure of the transaction, including collateral, if any. The allowance for lending-related commitments was $91 million at June 30, 2023 and $78 million at Dec. 31, 2022. A securities lending transaction is a fully collateralized transaction in which the owner of a security agrees to lend the security (typically through an agent, in our case, The Bank of New York Mellon) to a borrower, usually a broker-dealer or bank, on an open, overnight or term basis, under the terms of a prearranged contract. We typically lend securities with indemnification against borrower default. We generally require the borrower to provide collateral with a minimum value of 102% of the fair value of the securities borrowed, which is monitored on a daily basis, thus reducing credit risk. Market risk can also arise in securities lending transactions. These risks are controlled through policies limiting the level of risk that can be undertaken. Securities lending transactions are generally entered into only with highly rated counterparties. Securities lending indemnifications were secured by collateral of $481 billion at June 30, 2023 and $515 billion at Dec. 31, 2022. CIBC Mellon, a joint venture between BNY Mellon and the Canadian Imperial Bank of Commerce (“CIBC”), engages in securities lending activities. CIBC Mellon, BNY Mellon and CIBC jointly and severally indemnify securities lenders against specific types of borrower default. At June 30, 2023 and Dec. 31, 2022, $63 billion and $64 billion, respectively, of borrowings at CIBC Mellon, for which BNY Mellon acts as agent on behalf of CIBC Mellon clients, were secured by collateral of $66 billion and $68 billion, respectively. If, upon a default, a borrower’s collateral was not sufficient to cover its related obligations, certain losses related to the indemnification could be covered by the indemnitors. Unsettled repurchase and reverse repurchase agreements In the normal course of business, we enter into repurchase agreements and reverse repurchase agreements that settle at a future date. In repurchase agreements, BNY Mellon receives cash from and provides securities as collateral to a counterparty at settlement. In reverse repurchase agreements, BNY Mellon advances cash to and receives securities as collateral from the counterparty at settlement. These transactions are recorded on the consolidated balance sheet on the settlement date. At June 30, 2023, we had no unsettled repurchase agreements and $53.0 billion of unsettled reverse repurchase agreements. At Dec. 31, 2022, we had $4.0 billion of unsettled repurchase agreements and $11.3 billion of unsettled reverse repurchase agreements. Industry concentrations We have significant industry concentrations related to credit exposure at June 30, 2023. The tables below present our credit exposure in the financial institutions and commercial portfolios. Financial institutions portfolio exposure (in billions) June 30, 2023 Loans Unfunded Total exposure Securities industry $ 2.1 $ 17.3 $ 19.4 Asset managers 1.5 7.9 9.4 Banks 6.9 1.6 8.5 Insurance 0.1 3.8 3.9 Government — 0.2 0.2 Other 0.4 1.0 1.4 Total $ 11.0 $ 31.8 $ 42.8 Commercial portfolio exposure (in billions) June 30, 2023 Loans Unfunded Total exposure Manufacturing $ 0.6 $ 4.0 $ 4.6 Services and other 0.8 3.4 4.2 Energy and utilities 0.2 3.8 4.0 Media and telecom 0.1 0.7 0.8 Total $ 1.7 $ 11.9 $ 13.6 Major concentrations in securities lending are primarily to broker-dealers and are generally collateralized with cash and/or securities. Sponsored member repo program BNY Mellon is a sponsoring member in the FICC sponsored member program, where we submit eligible repurchase and reverse repurchase transactions in U.S. Treasury and agency securities (“Sponsored Member Transactions”) between BNY Mellon and our sponsored member clients for novation and clearing through FICC pursuant to the FICC Government Securities Division rulebook (the “FICC Rules”). We also guarantee to FICC the prompt and full payment and performance of our sponsored member clients’ respective obligations under the FICC Rules in connection with such clients’ Sponsored Member Transactions. We minimize our credit exposure under this guaranty by obtaining a security interest in our sponsored member clients’ collateral and rights under Sponsored Member Transactions. See “Offsetting assets and liabilities” in Note 17 for additional information on our repurchase and reverse repurchase agreements. Indemnification arrangements We have provided standard representations for underwriting agreements, acquisition and divestiture agreements, sales of loans and commitments, and other similar types of arrangements and customary indemnification for claims and legal proceedings related to providing financial services that are not otherwise included above. Insurance has been purchased to mitigate certain of these risks. Generally, there are no stated or notional amounts included in these indemnifications, and the contingencies triggering the obligation for indemnification are not expected to occur. Furthermore, often counterparties to these transactions provide us with comparable indemnifications. We are unable to develop an estimate of the maximum payout under these indemnifications for several reasons. In addition to the lack of a stated or notional amount in a majority of such indemnifications, we are unable to predict the nature of events that would trigger indemnification or the level of indemnification for a certain event. We believe, however, that the possibility that we will have to make any material payments for these indemnifications is remote. At June 30, 2023 and Dec. 31, 2022, we have not recorded any material liabilities under these arrangements. Clearing and settlement exchanges We are a noncontrolling equity investor in, and/or member of, several industry clearing or settlement exchanges through which foreign exchange, securities, derivatives or other transactions settle. Certain of these industry clearing and settlement exchanges require their members to guarantee their obligations and liabilities and/or to provide liquidity support in the event other members do not honor their obligations. We believe the likelihood that a clearing or settlement exchange (of which we are a member) would become insolvent is remote. Additionally, certain settlement exchanges have implemented loss allocation policies that enable the exchange to allocate settlement losses to the members of the exchange. It is not possible to quantify such mark-to-market loss until the loss occurs. Any ancillary costs that occur as a result of any mark-to-market loss cannot be quantified. In addition, we also sponsor clients as members on clearing and settlement exchanges and guarantee their obligations. At June 30, 2023 and Dec. 31, 2022, we did not record any material liabilities under these arrangements. Legal proceedings In the ordinary course of business, The Bank of New York Mellon Corporation and its subsidiaries are routinely named as defendants in or made parties to pending and potential legal actions. We also are subject to governmental and regulatory examinations, information-gathering requests, investigations and proceedings (both formal and informal). Claims for significant monetary damages are often asserted in many of these legal actions, while claims for disgorgement, restitution, penalties and/or other remedial actions or sanctions may be sought in governmental and regulatory matters. It is inherently difficult to predict the eventual outcomes of such matters given their complexity and the particular facts and circumstances at issue in each of these matters. However, on the basis of our current knowledge and understanding, we do not believe that judgments, settlements or orders, if any, arising from these matters (either individually or in the aggregate, after giving effect to applicable reserves and insurance coverage) will have a material adverse effect on the consolidated financial position or liquidity of BNY Mellon, although they could have a material effect on our results of operations in a given period. In view of the inherent unpredictability of outcomes in litigation and regulatory matters, particularly where (i) the damages sought are substantial or indeterminate, (ii) the proceedings are in the early stages, or (iii) the matters involve novel legal theories or a large number of parties, as a matter of course there is considerable uncertainty surrounding the timing or ultimate resolution of litigation and regulatory matters, including a possible eventual loss, fine, penalty or business impact, if any, associated with each such matter. In accordance with applicable accounting guidance, we establish accruals for litigation and regulatory matters when those matters proceed to a stage where they present loss contingencies that are both probable and reasonably estimable. In such cases, there may be a possible exposure to loss in excess of any amounts accrued. We regularly monitor such matters for developments that could affect the amount of the accrual, and will adjust the accrual amount as appropriate. If the loss contingency in question is not both probable and reasonably estimable, we do not establish an accrual and the matter continues to be monitored for any developments that would make the loss contingency both probable and reasonably estimable. We believe that our accruals for legal proceedings are appropriate and, in the aggregate, are not material to the consolidated financial position of BNY Mellon, although future accruals could have a material effect on the results of operations in a given period. In addition, if we have the potential to recover a portion of an estimated loss from a third party, we record a receivable up to the amount of the accrual that is probable of recovery. For certain of those matters described here for which a loss contingency may, in the future, be reasonably possible (whether in excess of a related accrued liability or where there is no accrued liability), BNY Mellon is currently unable to estimate a range of reasonably possible loss. For those matters described here where BNY Mellon is able to estimate a reasonably possible loss, the aggregate range of such reasonably possible loss is up to $620 million in excess of the accrued liability (if any) related to those matters. For matters where a reasonably possible loss is denominated in a foreign currency, our estimate is adjusted quarterly based on prevailing exchange rates. We do not consider potential recoveries when estimating reasonably possible losses. The following describes certain judicial, regulatory and arbitration proceedings involving BNY Mellon: Mortgage-Securitization Trusts Proceedings BNY Mellon has been named as a defendant in a number of legal actions brought by MBS investors alleging that the trustee has expansive duties under the governing agreements, including the duty to investigate and pursue breach of representation and warranty claims against other parties to the MBS transactions. Two actions commenced in December 2015 and February 2017 are pending in New York federal court. An action commenced in December 2014 in New York federal court was dismissed and the dismissal was affirmed on appeal in April 2023. In New York state court, six actions are pending: one case commenced in May 2016; two related cases commenced in September 2021 and October 2022; and three related cases commenced in October 2021, December 2021 and February 2022. Matters Related to R. Allen Stanford In late December 2005, Pershing LLC (“Pershing”) became a clearing firm for Stanford Group Co. (“SGC”), a registered broker-dealer that was part of a group of entities ultimately controlled by R. Allen Stanford (“Stanford”). Stanford International Bank, also controlled by Stanford, issued certificates of deposit (“CDs”). Some investors allegedly wired funds from their SGC accounts to purchase CDs. In 2009, the Securities and Exchange Commission charged Stanford with operating a Ponzi scheme in connection with the sale of CDs, and SGC was placed into receivership. Alleged purchasers of CDs have filed two putative class action proceedings against Pershing: one in November 2009 in Texas federal court, and one in May 2016 in New Jersey federal court. On Nov. 5, 2021, the court dismissed the class action filed in New Jersey and that matter has concluded. Three lawsuits remain against Pershing in Louisiana and New Jersey federal courts, which were filed in January 2010, October 2015 and May 2016. The purchasers allege that Pershing, as SGC’s clearing firm, assisted Stanford in a fraudulent scheme and assert contractual, statutory and common law claims. In March 2019, a group of investors filed a putative class action against The Bank of New York Mellon in New Jersey federal court, making the same allegations as in the prior actions brought against Pershing. On Nov. 12, 2021, the court dismissed the class action against The Bank of New York Mellon; on Dec. 15, 2022, an appeals court reversed the dismissal and returned the case to the trial court for further proceedings. All the cases that have been brought in federal court against Pershing have been consolidated in Texas federal court for discovery purposes. Various alleged Stanford CD purchasers asserted similar claims in Financial Industry Regulatory Authority, Inc. (“FINRA”) arbitration proceedings. Brazilian Postalis Litigation BNY Mellon Servicos Financeiros DTVM S.A. (“DTVM”), a subsidiary that provides asset services in Brazil, acts as administrator for certain investment funds in which a public pension fund for postal workers called Postalis-Instituto de Seguridade Social dos Correios e Telégrafos (“Postalis”) invested. On Aug. 22, 2014, Postalis sued DTVM in Rio de Janeiro, Brazil for losses related to a Postalis fund for which DTVM is administrator. Postalis alleges that DTVM failed to properly perform duties, including to conduct due diligence of and exert control over the manager. On March 12, 2015, Postalis filed a lawsuit in Rio de Janeiro against DTVM and BNY Mellon Administração de Ativos Ltda. (“Ativos”) alleging failure to properly perform duties relating to another fund of which DTVM is administrator and Ativos is manager. On Dec. 14, 2015, Associacão dos Profissionais dos Correios (“ADCAP”), a Brazilian postal workers association, filed a lawsuit in São Paulo against DTVM and other defendants alleging that DTVM improperly contributed to Postalis investment losses. On March 20, 2017, the lawsuit was dismissed without prejudice, and ADCAP appealed. On Aug. 4, 2021, the appellate court overturned the dismissal and sent the lawsuit to a state lower court. On March 2, 2023, DTVM appealed the August 4 decision to Brazil’s Superior Court of Justice. On Dec. 17, 2015, Postalis filed three lawsuits in Rio de Janeiro against DTVM and Ativos alleging failure to properly perform duties with respect to investments in several other funds. On May 20, 2021, the court in one of those lawsuits entered a judgment of approximately $3 million against DTVM and Ativos. On Aug. 23, 2021, DTVM and Ativos filed an appeal of the May 20 decision. On June 7, 2022, the appellate court partially granted and partially denied the appeal, reducing the judgment to approximately $2 million. On July 13, 2023, DTVM and Ativos filed a further appeal to Brazil’s Superior Court of Justice. On Aug. 24, 2022, the court dismissed one of the other lawsuits. On Nov. 24, 2022, Postalis appealed that decision. On Feb. 4, 2016, Postalis filed a lawsuit in Brasilia against DTVM, Ativos and BNY Mellon Alocação de Patrimônio Ltda. (“Alocação de Patrimônio”), an investment management subsidiary, alleging failure to properly perform duties and liability for losses with respect to investments in various funds of which the defendants were administrator and/or manager. On Jan. 16, 2018, the Brazilian Federal Prosecution Service (“MPF”) filed a civil lawsuit in São Paulo against DTVM alleging liability for Postalis losses based on alleged failures to properly perform certain duties as administrator to certain funds in which Postalis invested or as controller of Postalis’s own investment portfolio. On April 18, 2018, the court dismissed the lawsuit without prejudice. On Aug. 4, 2021, the appellate court overturned the dismissal and returned the lawsuit to the lower court. On April 11, 2022, DTVM appealed the Aug. 4 decision to Brazil’s Superior Court of Justice. In addition, the Tribunal de Contas da União (“TCU”), an administrative tribunal, has initiated proceedings with the purpose of determining liability for losses to three investment funds administered by DTVM in which Postalis was an investor. On Sept. 9, 2020, TCU rendered a decision in one of the proceedings, finding DTVM and two former Postalis directors jointly and severally liable for approximately $50 million. TCU also imposed on DTVM a fine of approximately $2 million. DTVM’s administrative appeal of the decision was denied. On Feb. 25, 2022, DTVM filed a lawsuit in Brazil federal court in Brasilia seeking annulment of TCU’s decision and an injunction preventing TCU from enforcing the judgment. On Aug. 24, 2022, the Brazilian Federal Attorneys filed an action in Rio de Janeiro court seeking to enforce the fine portion of the judgment. On Nov. 8, 2022, the Brasilia federal court in the annulment action granted DTVM’s request for an injunction, suspending the Sept. 9, 2020 TCU decision until the annulment action is decided. On Oct. 4, 2019, Postalis and another pension fund filed a request for arbitration in São Paulo against DTVM and Ativos alleging liability for losses to an investment fund for which DTVM was administrator and Ativos was manager. On March 26, 2021, DTVM and Ativos filed a lawsuit in São Paulo challenging the decision rendered by the Arbitration Court with respect to its jurisdiction over the case. On Feb. 24, 2023, the São Paulo court annulled the Arbitration Court’s decision that it had jurisdiction. On Oct. 25, 2019, Postalis filed a lawsuit in Rio de Janeiro against DTVM and Alocação de Patrimônio, alleging liability for losses in another fund for which DTVM was administrator and Alocação de Patrimônio and Ativos were managers. On May 9, 2022, the court found DTVM and Alocação de Patrimônio jointly and severally liable for approximately $20 million. On Aug. 12, 2022, DTVM and Alocação de Patrimônio appealed the decision. On June 19, 2020, a lawsuit was filed in federal court in Rio de Janeiro against DTVM, Postalis, and various other defendants alleging liability against DTVM for certain Postalis losses in an investment fund of which DTVM was administrator. On Feb. 10, 2021, Postalis and another pension fund served DTVM in a lawsuit filed in Rio de Janeiro, alleging liability for losses in another investment fund for which DTVM was administrator and the other defendant was manager. Brazilian Silverado Litigation DTVM acts as administrator for the Fundo de Investimento em Direitos Creditórios Multisetorial Silverado Maximum (“Silverado Maximum Fund”), which invests in commercial credit receivables. On June 2, 2016, the Silverado Maximum Fund sued DTVM in its capacity as administrator, along with Deutsche Bank S.A. - Banco Alemão in its capacity as custodian and Silverado Gestão e Investimentos Ltda. in its capacity as investment manager. The Fund alleges that each of the defendants failed to fulfill its respective duty, and caused losses to the Fund for which the defendants are jointly and severally liable. German Tax Matters German authorities are investigating past “cum/ex” trading, which involved the purchase of equity securities on or shortly before the dividend date, but settled after that date, potentially resulting in an unwarranted refund of withholding tax. German authorities have taken the view that past cum/ex trading may have resulted in tax avoidance or evasion. European subsidiaries of BNY Mellon have been informed by German authorities about investigations into potential cum/ex trading by certain third-party investment funds, where one of the subsidiaries had acquired entities that served as depositary and/or fund manager for those third-party investment funds. We have received information requests from the authorities relating to pre- acquisition activity and are cooperating fully with those requests. In August 2019, the District Court of Bonn ordered that one of these subsidiaries be joined as a secondary party in connection with the prosecution of unrelated individual defendants. Trial commenced in September 2019. In March 2020, the court stated that it would refrain from taking action against the subsidiary in order to expedite the conclusion of the trial. The court convicted the unrelated individual defendants, and determined that the cum/ex trading activities of the relevant third-party investment funds were unlawful. In November and December 2020 and February 2023, we received secondary liability notices from the German tax authorities totaling approximately $150 million (at then-prevailing exchange rates) related to pre-acquisition activity in various funds for which the entities we acquired were depositary and/or fund manager. We have appealed the notices. In connection with the acquisition of the subject entities, we obtained an indemnity for liabilities from the sellers that we intend to pursue as necessary. Off-Channel Business-Related Communications The Company has been responding to a request for information from the SEC concerning compliance with recordkeeping obligations relating to business communications transmitted on unapproved electronic communication platforms. SEC Staff has stated that it is conducting similar inquiries into recordkeeping practices at other financial institutions. The Company is cooperating with the inquiry. In April 2023, the Company received a similar request from the Commodity Futures Trading Commission and is cooperating with that inquiry as well.

Segment Reporting [Abstract]
Business segments	Business segments We have an internal information system that produces performance data along product and service lines for our three principal business segments and the Other segment. The primary products and services and types of revenue for our principal businesses and a description of the Other segment are presented in Note 24 of the Notes to Consolidated Financial Statements in our 2022 Annual Report. Business accounting principles Our business data has been determined on an internal management basis of accounting, rather than GAAP which is used for consolidated financial reporting. These measurement principles are designed so that reported results of the businesses will track their economic performance. Business segment results are subject to reclassification when organizational changes are made, or for refinements in revenue and expense allocation methodologies. Refinements are typically reflected on a prospective basis. There were no reclassification or organization changes in the second quarter of 2023. The accounting policies of the businesses are the same as those described in Note 1 of the Notes to Consolidated Financial Statements in our 2022 Annual Report. The results of our business segments are presented and analyzed on an internal management reporting basis. • Revenue amounts reflect fee and other revenue generated by each business and include revenue for services provided between the segments that are also provided to third parties. Fee and other revenue transferred between businesses under revenue transfer agreements is included within other fees in each segment. • Revenues and expenses associated with specific client bases are included in those businesses. For example, foreign exchange activity associated with clients using custody products is included in the Securities Services segment. • Net interest revenue is allocated to businesses based on the yields on the assets and liabilities generated by each business. We employ a funds transfer pricing system that matches funds with the specific assets and liabilities of each business based on their interest sensitivity and maturity characteristics. • The provision for credit losses associated with the respective credit portfolios is reflected in each segment. • Incentives expense related to restricted stock and RSUs is allocated to the segments. • Support and other indirect expenses, including services provided between segments that are not provided to third parties or not subject to a revenue transfer agreement, are allocated to the businesses based on internally developed methodologies and reflected in noninterest expense. • Recurring FDIC expense is allocated to the businesses based on average deposits generated within each business. • Severance expense is recorded in the segments based on the business or function the impacted employees reside, with severance related to corporate staff, technology and operations reflected in the Other segment. • Litigation expense is generally recorded in the business in which the charge occurs. • Management of the securities portfolio is a shared service contained in the Other segment. As a result, gains and losses associated with the valuation of the securities portfolio are generally included in the Other segment. • Client deposits serve as the primary funding source for our securities portfolio. We typically allocate all interest revenue to the businesses generating the deposits. Accordingly, accretion related to the portion of the securities portfolio restructured in 2009 has been included in the results of the businesses. • Balance sheet assets and liabilities and their related income or expense are specifically assigned to each business. Segments with a net liability position have been allocated assets. • Goodwill and intangible assets are reflected within individual businesses. The following consolidating schedules present the contribution of our segments to our overall profitability.

Accounting Policies [Abstract]
Basis of presentation	Basis of presentation The accounting and financial reporting policies of BNY Mellon, a global financial services company, conform to U.S. generally accepted accounting principles (“GAAP”) and prevailing industry practices. For information on our significant accounting and reporting policies, see Note 1 of the Notes to Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended Dec. 31, 2022 (the “2022 Annual Report”).
Reclassifications	Certain additional immaterial reclassifications have been made to prior periods to place them on a basis comparable with the current period presentation.
Use of estimates	Use of estimatesThe preparation of financial statements in conformity with U.S. GAAP requires management to make estimates based upon assumptions about future economic and market conditions which affect reported amounts and related disclosures in our financial statements. Although our current estimates contemplate current conditions and how we expect them to change in the future, it is reasonably possible that actual conditions could be worse than anticipated in those estimates, which could materially affect our results of operations and financial condition.
New accounting guidance	Accounting Standards Update (“ASU”) 2022-01, Derivatives and Hedging (Topic 815): Fair Value Hedging – Portfolio Layer Method In March 2022, the FASB issued ASU 2022-01, Derivatives and Hedging (Topic 815): Fair Value Hedging – Portfolio Layer Method , which provides guidance that expands the ability to hedge interest rate risk by permitting the use of multiple hedged layers of a single closed portfolio of assets and will (1) Allow multiple layer hedging within the same closed portfolio, (2) Expand the scope of the portfolio layer method to include non-prepayable assets, (3) Expand the eligible hedging instruments to be utilized in a single-layer hedge, and (4) Permit held-to-maturity debt securities to be transferred to available-for-sale at the date of adoption, provided such transferred securities are designated in a portfolio layer method hedge within 30 days of the adoption date. The standard also provides further guidance and disclosure requirements with respect to hedge basis adjustments related to portfolio layer method hedges. We adopted this guidance as of Jan. 1, 2023. The Company did not choose to make the one-time election to reclassify securities classified as held-to-maturity to available-for-sale as of Jan. 1, 2023 and can choose to prospectively apply portfolio layer method hedging. ASU 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures In March 2022, the FASB issued ASU 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures , which provides post-implementation guidance related to the adoption of ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments , which was effective Jan. 1, 2020. This ASU amends the guidance related to two issues: Troubled Debt Restructurings (“TDRs”) and disclosure requirements for the credit profile of the loan portfolio. This ASU eliminates the accounting guidance for TDRs by creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. An entity must apply the loan refinancing and restructuring guidance to determine whether a modification results in a new loan or a continuation of an existing loan. This ASU also requires that an entity disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20, Financial Instruments – Credit Losses – Measured at Amortized Cost .
Fair value measurement	Fair value measurementFair value is defined as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date. A three-level hierarchy for fair value measurements is utilized based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. BNY Mellon’s own creditworthiness is considered when valuing liabilities. See Note 20 of the Notes to Consolidated Financial Statements in our 2022 Annual Report for information on how we determine fair value and the fair value hierarchy.
