Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The accounting and financial reporting policies of State Street Corporation conform to U.S. GAAP. State Street Corporation, the Parent Company, is a financial holding company headquartered in Boston, Massachusetts. Unless otherwise indicated or unless the context requires otherwise, all references in these notes to consolidated financial statements to “State Street,” “we,” “us,” “our” or similar references mean State Street Corporation and its subsidiaries on a consolidated basis, including our principal banking subsidiary, State Street Bank. The accompanying consolidated financial statements should be read in conjunction with the financial and risk factor information included in our 2023 Form 10-K, which we previously filed with the SEC. The consolidated financial statements accompanying these condensed notes are unaudited. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, which are necessary for a fair statement of the consolidated results of operations in these financial statements, have been made. Certain previously reported amounts presented in this Form 10-Q have been reclassified to conform to current-period presentation. Events occurring subsequent to the date of our consolidated statement of condition were evaluated for potential recognition or disclosure in our consolidated financial statements through the date we filed this Form 10-Q with the SEC. The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions in the application of certain of our significant accounting policies that may materially affect the reported amounts of assets, liabilities, equity, revenue and expenses. As a result of unanticipated events or circumstances, actual results could differ from those estimates. Our consolidated statement of condition as of December 31, 2023 included in the accompanying consolidated financial statements was derived from the audited financial statements as of that date, but does not include all notes required by U.S. GAAP for a complete set of consolidated financial statements. Cash and Cash Equivalents Sanctions programs or government intervention may inhibit our ability to access cash and due from banks in certain accounts. For example, as of September 30, 2024 and December 31, 2023, we held such accounts in Russia that were subject to sanctions restrictions, inclusive of $0.8 billion and $1.5 billion, respectively, with our subcustodian, which is an affiliate of a large multinational bank, and with western European-based clearing agencies, for a total of approximately $1.4 billion and $1.9 billion, respectively. The reduction in balances with our subcustodian in Russia was a result of various actions taken re lated to our contractual arrangements that resulted in the derecognition of certain cash balances and related client liabilities. Cash and due from banks is evaluated as part of our allowance for credit losses. Recent Accounting Developments Relevant standards that were recently issued but not yet adopted as of September 30, 2024: Standard Description Effective Date Effects on the financial statements or other significant matters ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures The amendments related to the rate reconciliation and income taxes paid disclosures and require disclosures of (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. Additional amendments require (1) disclosures of pretax income (or loss) and income tax expense (or benefit) to be consistent with U.S. Securities and Exchange Commission regulations, and (2) remove disclosures that no longer are considered cost beneficial or relevant. Annual reporting for period ending December 31, 2025 We are currently evaluating the disclosure impact of the new standard. ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures The amendments enhance segment reporting by expanding the breadth and frequency of segment disclosures, including disclosure of (1) significant segment expenses, (2) other segment items, (3) the chief operating decision maker’s title and position and (4) how the chief operating decision maker uses the reported information to assess segment performance and how to allocate resources. The amendments also require these disclosures to be included in interim reporting. Annual reporting for period ending December 31, 2024 and for interim reporting in 2025 We are currently evaluating the disclosure impact of the new standard. Additionally, we continue to evaluate other accounting standards that were recently issued, but not yet adopted as of September 30, 2024; none are expected to have a material impact to our financial statements.

Fair Value Disclosures [Abstract]
Fair Value	Fair Value Fair Value Measurements We carry trading account assets and liabilities, AFS debt securities, certain equity securities and various types of derivative financial instruments, at fair value in our consolidated statement of condition on a recurring basis. Changes in the fair values of these financial assets and liabilities are recorded either as components of our consolidated statement of income or as components of AOCI within shareholders' equity in our consolidated statement of condition. We measure fair value for the above-described financial assets and liabilities in conformity with U.S. GAAP that governs the measurement of the fair value of financial instruments. Management believes that its valuation techniques and underlying assumptions used to measure fair value conform to the provisions of U.S. GAAP. We categorize the financial assets and liabilities that we carry at fair value based on a prescribed three-level valuation hierarchy. For information about our valuation techniques for financial assets and financial liabilities measured at fair value and the fair value hierarchy, refer to pages 134 to 139 in Note 2 to the consolidated financial statements included under Item 8, Financial Statements and Supplementary Data, in our 2023 Form 10-K.

Investments, Debt and Equity Securities [Abstract]
Investment Securities	Investment Securities Investment securities held by us are classified as either trading account assets, AFS, HTM or equity securities held at fair value at the time of purchase and reassessed periodically, based on management’s intent. For additional information on our accounting for investment securities, refer to page 140 in Note 3 to the consolidated financial statements included under Item 8, Financial Statements and Supplementary Data, in our 2023 Form 10-K. Trading assets are carried at fair value. Both realized and unrealized gains and losses on trading assets are recorded in other fee revenue in our consolidated statement of income. AFS securities are carried at fair value, with any allowance for credit losses recorded through the consolidated statement of income and after-tax net unrealized gains and losses are recorded in AOCI. Gains or losses realized on sales of AFS investment securities are computed using the specific identification method and are recorded in gains (losses) related to investment securities, net, in our consolidated statement of income. HTM investment securities are carried at cost, adjusted for amortization of premiums and accretion of discounts, with any allowance for credit losses recorded through the consolidated statement of income. The following table presents the amortized cost, fair value and associated unrealized gains and losses of AFS and HTM investment securities as of the dates indicated: September 30, 2024 December 31, 2023 Amortized Gross Fair Amortized Gross Fair (In millions) Gains Losses Gains Losses Available-for-sale: U.S. Treasury and federal agencies: Direct obligations $ 19,146 $ 38 $ 60 $ 19,124 $ 8,427 $ 39 $ 165 $ 8,301 Mortgage-backed securities (1) 11,270 78 88 11,260 10,870 49 164 10,755 Total U.S. Treasury and federal agencies 30,416 116 148 30,384 19,297 88 329 19,056 Non-U.S. debt securities: Mortgage-backed securities 2,536 4 3 2,537 1,861 3 7 1,857 Asset-backed securities (2) 2,289 6 2 2,293 2,148 2 13 2,137 Non-U.S. sovereign, supranational and non-U.S. agency 15,225 98 34 15,289 15,159 73 132 15,100 Other (3) 2,842 58 4 2,896 2,733 39 37 2,735 Total non-U.S. debt securities 22,892 166 43 23,015 21,901 117 189 21,829 Asset-backed securities: Student loans (4) 91 2 — 93 113 1 — 114 Collateralized loan obligations (5) 3,054 4 — 3,058 2,530 3 6 2,527 Non-agency CMBS and RMBS (6) 1 4 — 5 252 — 3 249 Other 90 1 — 91 90 — — 90 Total asset-backed securities 3,236 11 — 3,247 2,985 4 9 2,980 State and political subdivisions 151 — — 151 356 — 1 355 Other U.S. debt securities (7) 58 — 2 56 314 — 8 306 Total available-for-sale securities (8)(9) $ 56,753 $ 293 $ 193 $ 56,853 $ 44,853 $ 209 $ 536 $ 44,526 Held-to-maturity: U.S. Treasury and federal agencies: Direct obligations $ 5,589 $ — $ 64 $ 5,525 $ 8,584 $ — $ 163 $ 8,421 Mortgage-backed securities (10) 36,951 13 4,411 32,553 39,472 7 5,271 34,208 Total U.S. Treasury and federal agencies 42,540 13 4,475 38,078 48,056 7 5,434 42,629 Non-U.S. debt securities: Non-U.S. sovereign, supranational and non-U.S. agency 4,332 9 77 4,264 5,757 8 153 5,612 Total non-U.S. debt securities 4,332 9 77 4,264 5,757 8 153 5,612 Asset-backed securities: Student loans (4) 2,605 5 27 2,583 3,298 2 62 3,238 Non-agency CMBS and RMBS (11) — — — — 6 18 — 24 Total asset-backed securities 2,605 5 27 2,583 3,304 20 62 3,262 Total held-to-maturity securities (8)(12) $ 49,477 $ 27 $ 4,579 $ 44,925 $ 57,117 $ 35 $ 5,649 $ 51,503 (1) As of September 30, 2024 and December 31, 2023, the total fair value included $4.81 billion and $5.54 billion, respectively, of agency CMBS and $6.45 billion and $5.21 billion, respectively, of agency MBS.

The level rate of return considers any non-refundable fees or costs, as well as purchase premiums or discounts, adjusted as prepayments occur, resulting in amortization or accretion, accordingly. Allowance for Credit Losses on Debt Securities and Impairment of AFS Securities We conduct quarterly reviews of HTM and AFS securities on a collective (pool) basis when similar risk characteristics exist to determine whether an allowance for credit losses should be recognized. We review individual AFS securities periodically to assess if additional impairment is required. For additional information about the Current Expected Credit Loss methodology and the review of investment securities for expected credit losses or impairment, refer to page 145 to 146 in Note 3 to the consolidated financial statements included under Item 8, Financial Statements and Supplementary Data, in our 2023 Form 10-K. We monitor the credit quality of the HTM and AFS investment securities using a variety of methods, including both external and internal credit ratings. As of September 30, 2024, over 99% of our HTM and AFS investment portfolio is publicly rated investment grade. As of both September 30, 2024 and December 31, 2023, we had an allowance for credit losses on HTM investment securities of $1 million. In the third quarter of 2024, we recorded no provision for credit losses and no charge-offs on HTM securities. As of both September 30, 2024 and December 31, 2023, we had no allowance for credit losses on AFS investment securities. In the third quarter of 2024, we recorded no provision for credit losses and no charge-offs on AFS securities. We have elected to not record an allowance on accrued interest for HTM and AFS securities. Accrued interest on these securities is reversed against interest income when payment on a security is delinquent for greater than 90 days from the date of payment. After a review of the investment portfolio, taking into consideration then-current economic conditions, adverse situations that might affect our ability to fully collect principal and interest, the timing of future payments, the credit quality and performance of the collateral underlying MBS and ABS and other relevant factors, management considered the aggregate decline in fair value of the investment securities portfolio and the resulting gross pre-tax unrealized losses of $4.77 billion related to 1,478

Credit Loss [Abstract]
Loans and Allowance for Credit Losses	Loans and Allowance for Credit Losses We segregate our loans into two segments: commercial and financial loans and commercial real estate loans. We further classify commercial and financial loans as fund finance loans, leveraged loans, collateralized loan obligations in loan form, overdrafts and other loans. These classifications reflect their risk characteristics, their initial measurement attributes and the methods we use to monitor and assess credit risk. For additional information on our loans, including our internal risk-rating system used to assess our risk of credit loss for each loan, refer to pages 146 to 151 in Note 4 to the consolidated financial statements included under Item 8, Financial Statements and Supplementary Data, in our 2023 Form 10-K. The following table presents our recorded investment in loans, by segment, as of the dates indicated: (In millions) September 30, 2024 December 31, 2023 Domestic (1) : Commercial and financial: Fund finance (2) $ 14,676 $ 13,697 Leveraged loans 2,708 2,412 Overdrafts 1,738 1,225 Collateralized loan obligations in loan form 50 150 Other (3) 2,846 2,512 Commercial real estate 2,856 3,069 Total domestic $ 24,874 $ 23,065 Foreign (1) : Commercial and financial: Fund finance (2) $ 6,369 $ 4,956 Leveraged loans 1,142 1,194 Overdrafts 1,758 1,047 Collateralized loan obligations in loan form 7,818 6,369 Total foreign 17,087 13,566 Total loans (4) 41,961 36,631 Allowance for credit losses (162) (135) Loans, net of allowance $ 41,799 $ 36,496 (1) Domestic and foreign categorization is based on the borrower’s country of domicile. (2) Fund finance loans include primarily $10.83 billion private equity capital call finance loans, $7.44 billion loans to real money funds and $1.48 billion loans to business development companies as of September 30, 2024, compared to $9.69 billion private equity capital call finance loans, $6.63 billion loans to real money funds and $1.05 billion loans to business development companies as of December 31, 2023. (3) Includes $2.61 billion securities finance loans and $236 million loans to municipalities as of September 30, 2024 and $2.23 billion securities finance loans, $276 million loans to municipalities and $5 million other loans as of December 31, 2023. (4) As of September 30, 2024, excluding overdrafts, floating rate loans totaled $35.67 billion and fixed rate loans totaled $2.79 billion. We have entered into interest rate swap agreements to hedge the forecasted cash flows associated with EURIBOR indexed floating-rate loans. See Note 10 to the consolidated financial statements in our 2023 Form 10-K for additional details. The commercial and financial segment is composed of primarily fund finance loans, purchased leveraged loans, purchased collateralized loan obligations in loan form, overdrafts and other loans. Fund finance loans are composed of revolving credit lines providing liquidity and leverage to mutual fund and private equity fund clients. These classifications reflect their risk characteristics, their initial measurement attributes and the methods we use to monitor and assess credit risk. Certain loans are pledged as collateral for access to the Federal Reserve's discount window. As of September 30, 2024 and December 31, 2023, the loans pledged as collateral totaled $13.30 billion and $13.00 billion, respectively. As of September 30, 2024 and December 31, 2023, we had two loans totaling $192 million and three loans totaling $70 million, respectively, on non-accrual status. In the third quarter of 2024, we purchased $802 million of collateralized loan obligations in loan form, which were all investment grade. We sold and settled $9 million of loans in the third quarter of 2024. Allowance for Credit Losses We recognize an allowance for credit losses in accordance with ASC 326 for financial assets held at amortized cost and off-balance sheet commitments. The allowance for credit losses is reviewed on a regular basis, and any provision for credit losses is recorded to reflect the amount necessary to maintain the allowance for expected credit losses at a level which represents what management does not expect to recover due to expected credit losses. For additional discussion on the allowance for credit losses for investment securities, please refer to Note 3 to the consolidated financial statements in this Form 10-Q. When the allowance is recorded, a provision for credit loss expense is recognized in net income. The allowance for credit losses for financial assets (excluding investment securities, as discussed in Note 3) represents the portion of the amortized cost basis, including accrued interest for financial assets held at amortized cost, which management does not expect to recover due to expected credit losses and is presented on the statement of condition as an offset to the amortized cost basis. The accrued interest balance is presented separately on the statement of condition within accrued interest and fees receivable. The allowance for off-balance sheet commitments is presented within other liabilities. Loans are charged off to the allowance for credit losses in the reporting period in which either an event occurs that confirms the existence of a loss on a loan, including a sale of a loan below its carrying value, or a portion of a loan is determined to be uncollectible. The allowance for credit losses may be determined using various methods, including discounted cash flow methods, loss-rate methods, probability-of-default methods, and other quantitative or qualitative methods as determined by us. The method used to estimate expected credit losses may vary depending on the type of financial asset, our ability to predict the timing of cash flows, and the information available to us. The allowance for credit losses as reported in our consolidated statement of condition is adjusted by provision for credit losses, which is reported in earnings, and reduced by the charge-off of principal amounts, net of recoveries. We measure expected credit losses of financial assets on a collective (pool) basis when similar risk characteristics exist. Each reporting period, we assess whether the assets in the pool continue to display similar risk characteristics. For a financial asset that does not share risk characteristics with other assets, expected credit losses are measured separately using one or more of the methods noted above. As of September 30, 2024, we had six loans totaling $79 million in the commercial and financial segment and four loans totaling $324 million in the commercial real estate segment that no longer met the similar risk characteristics of their collective pool. As of September 30, 2024, $77 million of our allowance for credit losses related to these loans. When the asset is collateral dependent, which means when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral, expected credit losses are measured as the difference between the amortized cost basis of the asset and the fair value of the collateral, adjusted for the estimated costs to sell. Determining the appropriateness of the allowance is complex and requires judgment by management about the effect of matters that are inherently uncertain. In future periods, factors and forecasts then prevailing may result in significant changes in the allowance for credit losses in those future periods. We estimate credit losses over the contractual life of the financial asset, while factoring in prepayment activity, where supported by data, over a three year reasonable and supportable forecast period. We utilize a baseline, upside and downside scenario which are applied based on a probability weighting, in order to better reflect management’s expectation of expected credit losses given existing market conditions and the changes in the economic environment. The multiple scenarios are based on a three-year horizon (or less depending on contractual maturity) and then revert linearly over a two-year period to a ten-year historical average thereafter. The contractual term excludes expected extensions, renewals and modifications, but includes prepayment assumptions where applicable. As part of our allowance methodology, we establish qualitative reserves to address any risks inherent in our portfolio that are not addressed through our quantitative reserve assessment. These factors may relate to, among other things, legislation changes or new regulation, credit concentration, loan markets, scenario weighting and overall model limitations. The qualitative adjustments are applied to our portfolio of financial instruments under the existing governance structure and are inherently judgmental. For additional information on the allowance for credit losses, refer to pages 146 to 151 in Note 4 to the consolidated financial statements included under Item 8, Financial Statements and Supplementary Data, in our 2023 Form 10-K. Credit Quality Credit quality for financial assets held at amortized cost is continuously monitored by management and is reflected within the allowance for credit losses. We use an internal risk-rating system to assess our risk of credit loss for each loan. This risk-rating process incorporates the use of risk-rating tools in conjunction with management judgment. Qualitative and quantitative inputs are captured in a systematic manner, and following a formal review and approval process, an internal credit rating based on our credit scale is assigned. When computing allowance levels, credit loss assumptions are estimated using models that categorize asset pools based on loss history, delinquency status and other credit trends and risk characteristics, including current conditions and reasonable and supportable forecasts about the future. Determining the appropriateness of the allowance is complex and requires judgment by management about the effect of matters that are inherently uncertain. In future periods, evaluations of the overall asset portfolio, in light of the factors and forecasts then prevailing, may result in significant changes in the allowance and credit loss expense in those future periods. Credit quality is assessed and monitored by evaluating various attributes in order to enable timely detection of any concerns with the customer’s credit rating. The results of those evaluations are utilized in underwriting new loans and transactions with counterparties and in our process for estimation of expected credit losses. In assessing the risk rating assigned to each individual loan, among the factors considered are the borrower's debt capacity, collateral coverage, payment history and delinquency experience, financial flexibility and earnings strength, the expected amounts and source of repayment, the level and nature of contingencies, if any, and the industry and geography in which the borrower operates. These factors are based on an evaluation of historical and current information, and involve subjective assessment and interpretation. Credit counterparties are evaluated and risk-rated on an individual basis at least annually. Management considers the ratings to be current as of September 30, 2024. Our internal risk rating methodology assigns risk ratings to counterparties ranging from Investment Grade, Speculative, Special Mention, Substandard, Doubtful and Loss. • Investment Grade: Counterparties with strong credit quality and low expected credit risk and probability of default. Approximately 87% of our loans were rated as investment grade as of September 30, 2024 with external credit ratings, or equivalent, of "BBB-" or better. • Speculative: Counterparties that have the ability to repay but face significant uncertainties, such as adverse business or financial circumstances that could affect credit risk or economic downturns. Loans to counterparties rated as speculative account for approximately 11% of our loans as of September 30, 2024, and are concentrated in leveraged loans. Approximately 92% of those leveraged loans have an external credit rating, or equivalent, of "BB" or "B" as of September 30, 2024. • Special Mention: Counterparties with potential weaknesses that, if uncorrected, may result in deterioration of repayment prospects. • Substandard: Counterparties with well-defined weakness that jeopardizes repayment with the possibility we will sustain some loss. • Doubtful: Counterparties with well-defined weakness which make collection or liquidation in full highly questionable and improbable. • Loss: Counterparties which are uncollectible or have little value. The following tables present our recorded loans to counterparties by risk rating, as noted above, as of the dates indicated: September 30, 2024 Commercial and Financial Commercial Real Estate Total Loans (In millions) Investment grade $ 34,566 $ 2,011 $ 36,577 Speculative 4,246 459 4,705 Special mention 214 62 276 Substandard 79 132 211 Doubtful — 192 192 Total (1) $ 39,105 $ 2,856 $ 41,961 December 31, 2023 Commercial and Financial Commercial Real Estate Total Loans (In millions) Investment grade $ 29,737 $ 2,287 $ 32,024 Speculative 3,546 449 3,995 Special mention 242 62 304 Substandard 14 224 238 Doubtful 23 47 70 Total (1) $ 33,562 $ 3,069 $ 36,631 (1) Loans include $3.50 billion and $2.27 billion of overdrafts as of September 30, 2024 and December 31, 2023, respectively. Overdrafts are short-term in nature and do not present a significant credit risk to us. As of September 30, 2024, $3.11 billion overdrafts were investment grade and $0.39 billion overdrafts were speculative. For additional information about credit quality, refer to pages 146 to 151 in Note 4 to the consolidated financial statements included under Item 8, Financial Statements and Supplementary Data, in our 2023 Form 10-K. The following table presents the amortized cost basis, by year of origination and credit quality indicator, as of September 30, 2024. For origination years before the fifth annual period, we present the aggregate amortized cost basis of loans. For purchased loans, the date of issuance is used to determine the year of origination, not the date of acquisition. For modified, extended or renewed lending arrangements, we evaluate whether a credit event has occurred which would consider the loan to be a new arrangement.

Loans are reviewed on a regular basis, and any provisions for credit losses that are recorded reflect management's estimate of the amount necessary to maintain the allowance for loan losses at a level considered appropriate to absorb expected credit losses in the loan portfolio. In the third quarter of 2024, we recorded a $26 million provision for credit losses, primarily reflecting an increase in loan loss reserves associated with certain commercial real estate and leveraged loans, combined with a change in macroeconomic factors. We did not record a provision for credit losses in the third quarter of 2023. Allowance estimates remain subject to continued model and economic uncertainty and management may use qualitative adjustments in the allowance estimates. If future data and forecasts deviate relative to the forecasts utilized to determine our allowance for credit losses as of September 30, 2024, or if credit risk migration is higher or lower than forecasted for reasons independent of the economic forecast, our allowance for credit losses will also change.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments We use derivative financial instruments to support our clients' needs and to manage our interest rate, currency and other market risks. These financial instruments consist of FX contracts such as forwards, futures and options contracts; interest rate contracts such as interest rate swaps (cross currency and single currency) and futures; and other derivative contracts. Derivative instruments used for risk management purposes that are highly effective in offsetting the risk being hedged are generally designated as hedging instruments in hedge accounting relationships, while others are economic hedges and not designated in hedge accounting relationships. For additional information on our use and accounting policies on derivative financial instruments, including derivatives not designated as hedging instruments, refer to pages 155 and 156 in Note 10 to the consolidated financial statements included under Item 8, Financial Statements and Supplementary Data, in our 2023 Form 10-K. Derivatives Designated as Hedging Instruments For additional information on our derivatives designated as hedging instruments, including our risk management objectives and hedging documentation methodologies, refer to pages 155 and 156 in Note 10 to the consolidated financial statements included under Item 8, Financial Statements and Supplementary Data, in our 2023 Form 10-K. Fair Value Hedges Derivatives designated as fair value hedges are utilized to mitigate the risk of changes in the fair values of recognized assets and liabilities, including long-term debt and AFS securities. We use interest rate and foreign exchange contracts in this manner to manage our exposure to changes in the fair value of hedged items caused by changes in interest rates and foreign exchange rates, respectively. Changes in the fair value of the derivative and changes in fair value of the hedged item due to changes in the hedged risk are recognized in earnings in the same line item. If a hedge is terminated, but the hedged item was not derecognized, all remaining adjustments to the carrying amount of the hedged item are amortized over a period that is consistent with the amortization of other discounts or premiums associated with the hedged item . Cash Flow Hedges Derivatives designated as cash flow hedges are utilized to offset the variability of cash flows of recognized assets, liabilities or forecasted transactions. We have entered into FX contracts to hedge the change in cash flows attributable to FX movements in foreign currency denominated investment securities. Additionally, we have entered into interest rate swap agreements to hedge the forecasted cash flows associated with EURIBOR indexed floating-rate loans, Deposit Facility Interest Rate (DFR) indexed ECB deposits and Interest Rate on Reserve Balances (IORB) indexed floating-rate cash deposits held across the Federal Reserve Bank system. The interest rate swaps synthetically convert the interest receipts from a variable-rate to a fixed-rate, thereby mitigating the risk attributable to changes in the EURIBOR, DFR and IORB. Changes in fair value of the derivatives designated as cash flow hedges are initially recorded in AOCI and then reclassified into earnings in the same period or periods during which the hedged forecasted transaction affects earnings and are presented in the same income statement line item as the earnings effect of the hedged item. If the hedge relationship is terminated, the change in fair value on the derivative recorded in AOCI is reclassified into earnings consistent with the timing of the hedged item. For hedge relationships that are discontinued because a forecasted transaction is not expected to occur according to the original hedge terms, any related derivative values recorded in AOCI are immediately recognized in earnings. The net loss associated with cash flow hedges expected to be reclassified from AOCI within 12 months of September 30, 2024, is approximately $149 million. The maximum length of time over which forecasted cash flows are hedge d is five years. Net Investment Hedges Derivatives categorized as net investment hedges are entered into to protect the net investment in our foreign operations against adverse changes in exchange rates. We use FX forward contracts to convert the foreign currency risk to U.S. dollars to mitigate our exposure to fluctuations in FX rates. The changes in fair value of the FX forward contracts are recorded, net of taxes, in the foreign currency translation component of other comprehensive income (OCI). The following table presents the aggregate contractual, or notional, amounts of derivative financial instruments, including those entered into for trading and asset-and-liability management activities as of the dates indicated: (In millions) September 30, 2024 December 31, 2023 Derivatives not designated as hedging instruments: Interest rate contracts: Futures $ 46,505 $ 12,668 Foreign exchange contracts: Forward, swap and spot 3,006,136 2,528,115 Options purchased 789 851 Options written 125 544 Futures 399 197 Other: Futures 179 125 Stable value contracts (1) 28,456 28,704 Deferred value awards (2) 283 289 Derivatives designated as hedging instruments: Interest rate contracts: Swap agreements 26,699 20,333 Foreign exchange contracts: Forward and swap 9,644 9,777 (1) The notional value of the stable value contracts represents our maximum exposure.

Derivatives Netting and Credit Contingencies Netting Derivatives receivable and payable as well as cash collateral from the same counterparty are netted in the consolidated statement of condition for those counterparties with whom we have legally binding master netting agreements in place. In addition to cash collateral received and transferred presented on a net basis, we also receive and transfer collateral in the form of securities, which mitigate credit risk but are not eligible for netting. Additional information on netting is provided in Note 8. Credit Contingencies Certain of our derivatives are subject to master netting agreements with our derivative counterparties containing credit risk-related contingent features, which requires us to maintain an investment grade credit rating with the various credit rating agencies. If our rating falls below investment grade, we would be in violation of the provisions, and counterparties to the derivatives could request immediate payment or demand full overnight collateralization on derivative instruments in liability positions. The aggregate fair value of all derivatives with credit contingent features and in a net liability position as of September 30, 2024 totaled approximately $2.89 billion, against which we provided $1.39 billion of collateral in the normal course of business. If our credit related contingent features underlying these agreements were triggered as of September 30, 2024, the maximum additional collateral we would be required to post to our counterparties is approximately $1.50 billion.

As a principal, we borrow securities from the lending client and then lend such securities to the subsequent borrower, either our client or a broker/dealer. Our right to receive and obligation to return collateral in connection with our securities lending transactions are recorded in other assets and other liabilities, respectively, in our consolidated statement of condition. As of September 30, 2024 and December 31, 2023, we had approximately $35.15 billion and $23.13 billion, respectively, of collateral provided and approximately $14.47 billion and $11.93 billion, respectively, of collateral received from clients in connection with our participation in principal securities finance transactions. FICC Guarantee As a sponsoring member in the FICC member program, we provide a guarantee to FICC in the event a customer fails to perform its obligations under a transaction. In order to minimize the risk associated with this guarantee, sponsored members acting as buyers generally grant a security interest in the subject securities received under and held on their behalf by State Street. Additionally, as a member of certain industry clearing and settlement exchanges, we may be required to pay a pro rata share of the losses incurred by the organization and provide liquidity support in the event of the default of another member to the extent that the defaulting member’s clearing fund obligation and the prescribed loss allocation is depleted. It is difficult to estimate our maximum possible exposure under the membership agreements, since this would require an assessment of future claims that may be made against us that have not yet occurred. At both September 30, 2024 and December 31, 2023, we did not record any liabilities under these arrangements. For additional information on our repurchase and reverse repurchase agreements, please refer to Note 8 to the consolidated financial statements in this Form 10-Q.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies Legal and Regulatory Matters In the ordinary course of business, we and our subsidiaries are involved in disputes, litigation, and governmental or regulatory inquiries and investigations, both pending and threatened. These matters, if resolved adversely against us or settled, may result in monetary awards or payments, fines and penalties or require changes in our business practices. The resolution or settlement of these matters is inherently difficult to predict. Based on our assessment of these pending matters, we do not believe that the amount of any judgment, settlement or other action arising from any pending matter is likely to have a material adverse effect on our consolidated financial condition. However, an adverse outcome or development in certain of the matters described below could have a material adverse effect on our consolidated results of operations for the period in which such matter is resolved, or an accrual is determined to be required, on our consolidated financial condition, or on our reputation. We evaluate our needs for accruals of loss contingencies related to legal and regulatory proceedings on a case-by-case basis. When we have a liability that we deem probable, and we deem the amount of such liability can be reasonably estimated as of the date of our consolidated financial statements, we accrue our estimate of the amount of loss. We also consider a loss probable and establish an accrual when we make, or intend to make, an offer of settlement. Once established, an accrual is subject to subsequent adjustment as a result of additional information. The resolution of legal and regulatory proceedings and the amount of reasonably estimable loss (or range thereof) are inherently difficult to predict, especially in the early stages of proceedings. Even if a loss is probable, an amount (or range) of loss might not be reasonably estimated until the later stages of the proceeding due to many factors such as the presence of complex or novel legal theories, the discretion of governmental authorities in seeking sanctions or negotiating resolutions in civil and criminal matters, the pace and timing of discovery and other assessments of facts and the procedural posture of the matter (collectively, "factors influencing reasonable estimates"). As of September 30, 2024, our aggregate accruals for loss contingencies for legal, regulatory and related matters totaled approximately $11 million , including potential fines by government agencies and civil litigation with respect to the matters specifically discussed below. To the extent that we have established accruals in our consolidated statement of condition for probable loss contingencies, such accruals may not be sufficient to cover our ultimate financial exposure associated with any settlements or judgments. Any such ultimate financial exposure, or proceedings to which we may become subject in the future, could have a material adverse effect on our businesses, on our future consolidated financial statements or on our reputation. As of September 30, 2024, for those matters for which we have accrued probable loss contingencies and for other matters for which loss is reasonably possible (but not probable) in future periods, and for which we are able to estimate a range of reasonably possible loss, our estimate of the aggregate reasonably possible loss (in excess of any accrued amounts) ranges up to approximately $30 million . Our estimate with respect to the aggregate reasonably possible loss is based upon currently available information and is subject to significant judgment and a variety of assumptions and known and unknown uncertainties, which may change quickly and significantly from time to time, particularly if and as we engage with applicable governmental agencies or plaintiffs in connection with a proceeding. Also, the matters underlying the reasonably possible loss will change from time to time. As a result, actual results may vary significantly from the current estimate. In certain pending matters, it is not currently feasible to reasonably estimate the amount or a range of reasonably possible loss, and such losses, which may be significant, are not included in the estimate of reasonably possible loss discussed above. This is due to, among other factors, the factors influencing reasonable estimates described above. An adverse outcome in one or more of the matters for which we have not estimated the amount or a range of reasonably possible loss, individually or in the aggregate, could have a material adverse effect on our businesses, on our future consolidated financial statements or on our reputation. Given that our actual losses from any legal or regulatory proceeding for which we have provided an estimate of the reasonably possible loss could significantly exceed such estimate, and given that we cannot estimate reasonably possible loss for all legal and regulatory proceedings as to which we may be subject now or in the future, no conclusion as to our ultimate exposure from current pending or potential legal or regulatory proceedings should be drawn from the current estimate of reasonably possible loss. The following discussion provides information with respect to significant legal, governmental and regulatory matters. Gomes, et al. v. State Street Corp. Eight participants in our Salary Savings Program filed a purported class action complaint in May 2021 on behalf of participants and beneficiaries who participated in the program and invested in our proprietary investment fund options between May 2015 and the present. The complaint named the plan sponsor as well as the committees overseeing the plan and their respective members as defendants, and alleged breach of fiduciary duty and violations of other duties owed to retirement plan participants under ERISA. We resolved this matter at a cost that was within our established accruals for loss contingencies. Edmar Financial Company, LLC et al v. Currenex, Inc. et al In August 2021, two former Currenex clients filed a putative civil class action lawsuit in the Southern District of New York alleging antitrust violations, fraud and a civil Racketeer Influenced and Corrupt Organization Act violation against Currenex, State Street and others. Pension Risk Transfer Litigation State Street Global Advisors Trust Company (“SSGA”) is named as a defendant in a series of purported class action complaints filed by participants in pension plans where, in each case, SSGA was hired as independent fiduciary on behalf of the pension plan to conduct an ERISA-compliant due diligence review of potential insurers who could assume the plan’s liabilities and satisfy its payment obligations through the purchase of a group annuity contract, consistent with DOL guidance. The complaints, collectively, allege violations of ERISA’s fiduciary and prohibited transaction rules against SSGA, the plan sponsors, and others. German Tax Matter In connection with a routine audit including the period 2013-2015, German tax authorities have questioned whether State Street should have withheld and be secondarily liable for certain taxes on dividends paid on securities of German issuers held as collateral over dividend record dates in client lending transactions with counterparties outside of Germany. OFAC Matter In June 2024, State Street entered into a settlement agreement with the U.S. Department of Treasury’s Office of Foreign Assets Control (OFAC) to resolve its investigation into apparent violations of OFAC’s Ukraine-/Russia-Related Sanctions Regulations. In connection with the settlement, we paid a civil monetary penalty of $7.45 million and made certain compliance commitments. Income Taxes In determining our provision for income taxes, we make certain judgments and interpretations with respect to tax laws in jurisdictions in which we have business operations. Because of the complex nature of these laws, in the normal course of our business, we are subject to challenges from U.S. and non-U.S. income tax authorities regarding the amount of income taxes due. These challenges may result in adjustments to the timing or amount of taxable income or deductions or the allocation of taxable income among tax jurisdictions. We recognize a tax benefit when it is more likely than not that our position will result in a tax deduction or credit. Unrecognized tax benefits totaled approximately $216 million and $237 million as of September 30, 2024 and December 31, 2023, respectively. We are presently under audit by a number of tax authorities. The earliest tax year open to examination in juri sdictions where we have material operations is 2015. Management believes that we have sufficiently accrued liabilities as of September 30, 2024 for potential tax exposures.

Variable Interest Entities	Variable Interest Entities For additional information on our accounting policy and our use of variable interest entities (VIEs), refer to pages 165 to 166 in Note 14 to the consolidated financial statements included under Item 8, Financial Statements and Supplementary Data, "Variable Interest Entities", in our 2023 Form 10-K. Interests in Investment Funds As of both September 30, 2024 and December 31, 2023, we had no cons olidated funds. As of both September 30, 2024 and December 31, 2023, we managed certain funds, considered VIEs, in which we held a variable interest, but for which we were not deemed to be the primary beneficiary. Our potential maximum loss exposure related to these unconsolidated funds totaled $20 million and $18 million as of September 30, 2024 and December 31, 2023, respectively, and represented the carrying value of our investments, which are recorded in other assets in our consolidated statement of condition. The amount of loss we may recognize during any period is limited to the carrying amount of our investments in the unconsolidated funds. We also held investments in low-income housing, production and investment tax credit entities, considered VIEs for which we were not deemed to be the primary beneficiary. As of September 30, 2024 and December 31, 2023, our potential maximum loss exposure related to these unconsolidated entities totaled $1.16 billion and $1.33 billion, respectively, most of which represented the carrying value of our investments which are recorded in other assets in our consolidated statement of condition. We account for our low-income housing tax credit investments (LIHTC) under the proportional amortization method. Effective January 1, 2023, we also elected to account for our investments in production tax credit investments under the proportional amortization method of accounting. Under the proportional amortization method, the initial cost of the investment is amortized based on a percentage of the actual income tax credits and other income tax benefits allocated in the current period versus the total estimated income tax credits and other income tax benefits expected to be received over the life of the investment. The net benefit, representing the difference between amortization of the investment balance, recognition of the income tax credits and recognition of other income tax benefits from the investment is recognized as a component of income tax expense. A s of September 30, 2024, we had investments in LIHTC and production tax credit investments of $736 million and $306 million, respectively, which are included in other assets in our consolidated statement of condition. Contingent contributions related to the renewable energy production tax credit investments were $46 million at September 30, 2024. These contributions are contingent on production and expected to be paid through 2034. Deferred contributions related to the LIHTC investments were $124 million at September 30, 2024. These deferred contributions are payable in accordance with the respective agreements and are expected to be paid through 2041. The following table presents the impact of our tax credit programs for which we have elected to apply proportional amortization accounting on our consolidated statement of income for the periods indicated: (In millions) Three Months Ended September 30, Nine Months Ended September 30, 2024 2023 2024 2023 Other income: Income (loss) recorded on investments within other fee revenue $ 7 $ 8 $ 18 $ 23 Income recorded in total revenue 7 8 18 23 Tax credits and benefits recognized in income tax expense 69 68 196 202 Proportional amortization recognized in income tax expense (55) (52) (154) (156) Net benefits included in income tax expense 14 16 42 46 Net benefit attributable to tax-advantaged investments included in the consolidated statement of income $ 21 $ 24 $ 60 $ 69

(2) Under the advanced approaches, credit risk RWA includes a CVA which reflects the risk of potential fair value adjustments for credit risk reflected in our valuation of over-the-counter derivative contracts. We used a simple CVA approach in conformity with the Basel III advanced approaches. (3) Under the current advanced approaches rules and regulatory guidance concerning operational risk models, RWA attributable to operational risk can vary substantially from period-to-period, without direct correlation to the effects of a particular loss event on our results of operations and financial condition and impacting dates and periods that may differ from the dates and periods as of and during which the loss event is reflected in our financial statements, with the timing and categorization dependent on the processes for model updates and, if applicable, model revalidation and regulatory review and related supervisory processes. An individual loss event can have a significant effect on the output of our operational RWA under the advanced approaches depending on the severity of the loss event and its categorization among the seven Basel-defined UOMs. (4) Minimum requirements include a CCB of 2.5% and a SCB of 2.5% for the advanced approaches and the standardized approach, respectively, a G-SIB surcharge of 1.0% and a countercyclical buffer of 0%. On June 26, 2024, we were notified by the Federal Reserve of the results from the 2024 supervisory stress test. Our SCB calculated under the 2024 supervisory stress test was well below the 2.5% minimum, resulting in an SCB at that floor, which will continue to remain in effect from October 1, 2024, through September 30, 2025. (5) State Street Bank is required to maintain a minimum Tier 1 leverage ratio of 5% as it is the insured depository institution subsidiary of State Street Corporation, a U.S. G-SIB. NA

As performance obligations are satisfied, we have an unconditional right to payment and billing is generally performed monthly or quarterly; therefore, we do not have significant contract assets. We had $143 million and $133 million of deferred revenue as of September 30, 2024 and December 31, 2023, respectively. Deferred revenue is a contract liability which represents payments received and accounts receivable recorded in advance of providing services and is included in accrued expenses and other liabilities in the consolidated statement of condition. In the three months ended September 30, 2024, we recognized revenue of $71 million relating to deferred revenue of $151 million as of June 30, 2024. In the nine months ended September 30, 2024, we recognized revenue of $113 million relating to deferred revenue of $133 million as of December 31, 2023. Transaction price allocated to the remaining performance obligations represents future, non-cancelable contracted revenue that has not yet been recognized, inclusive of deferred revenue that has been invoiced and non-cancelable amounts that will be invoiced and recognized as revenue in future periods. As of September 30, 2024, total remaining non-cancelable performance obligations for services and products not yet delivered, primarily comprised of software license sales and SaaS, were approximately $1.73 billion. We expect to recognize approximately half of this amount in revenue over the next three years, with the remainder to be recognized thereafter. No adjustments are made to the promised amount of consideration for the effects of a significant financing component as the period between when we transfer a promised service to a customer and when the customer pays for that service is expected to be one year or less.

Segments, Geographical Areas [Abstract]
Non-U.S. Activities	Non-U.S. Activities We define our non-U.S. activities as those revenue-producing business activities that arise from clients that are generally serviced or managed outside the U.S. Due to the integrated nature of our business, precise segregation of our U.S. and non-U.S. activities is not possible. Subjective estimates, assumptions and other judgments are applied to quantify the financial results and assets related to our non-U.S. activities, including our application of funds transfer pricing, our asset and liability management policies and our allocation of certain indirect corporate expenses. Management periodically reviews and updates its processes for quantifying the financial results and assets related to our non-U.S. activities. The following table presents our U.S. and non-U.S. financial results for the periods indicated: Three Months Ended September 30, 2024 2023 (In millions) Non-U.S. (1) U.S. Total Non-U.S. (1) U.S. Total Total revenue $ 1,339 $ 1,920 $ 3,259 $ 1,081 $ 1,610 $ 2,691 Income before income tax expense 326 599 925 130 381 511 Nine Months Ended September 30, 2024 2023 (In millions) Non-U.S. (1) U.S. Total Non-U.S. (1) U.S. Total Total revenue $ 4,071 $ 5,517 $ 9,588 $ 3,777 $ 5,125 $ 8,902 Income before income tax expense 968 1,467 2,435 819 1,296 2,115 (1) Geographic mix is generally based on the domicile of the entity servicing the funds and is not necessarily representative of the underlying asset mix. Management fees generated outside the U.S. were approximately 24% and 25% of total management fees in the three and nine months ended September 30, 2024, respectively, compared to approximately 25% and 26% in the three and nine months ended September 30, 2023, respectively. Servicing fees generated outside the U.S. were approximatel y 47% of total servicing fees in both the three and nine months ended September 30, 2024, compared to approximately 47% and 46% in the three and nine months ended September 30, 2023, respectively. Non-U.S. assets were $95.26 billion and $80.75 billion as of September 30, 2024 and 2023, respectively.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accounting and financial reporting policies of State Street Corporation conform to U.S. GAAP. State Street Corporation, the Parent Company, is a financial holding company headquartered in Boston, Massachusetts. Unless otherwise indicated or unless the context requires otherwise, all references in these notes to consolidated financial statements to “State Street,” “we,” “us,” “our” or similar references mean State Street Corporation and its subsidiaries on a consolidated basis, including our principal banking subsidiary, State Street Bank.
Consolidation	The consolidated financial statements accompanying these condensed notes are unaudited. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, which are necessary for a fair statement of the consolidated results of operations in these financial statements, have been made. Certain previously reported amounts presented in this Form 10-Q have been reclassified to conform to current-period presentation. Events occurring subsequent to the date of our consolidated statement of condition were evaluated for potential recognition or disclosure in our consolidated financial statements through the date we filed this Form 10-Q with the SEC.
Use of Estimates	The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions in the application of certain of our significant accounting policies that may materially affect the reported amounts of assets, liabilities, equity, revenue and expenses. As a result of unanticipated events or circumstances, actual results could differ from those estimates. Our consolidated statement of condition as of December 31, 2023 included in the accompanying consolidated financial statements was derived from the audited financial statements as of that date, but does not include all notes required by U.S. GAAP for a complete set of consolidated financial statements.
Cash and Cash Equivalents	Cash and Cash Equivalents Sanctions programs or government intervention may inhibit our ability to access cash and due from banks in certain accounts. For example, as of September 30, 2024 and December 31, 2023, we held such accounts in Russia that were subject to sanctions restrictions, inclusive of $0.8 billion and $1.5 billion, respectively, with our subcustodian, which is an affiliate of a large multinational bank, and with western European-based clearing agencies, for a total of approximately $1.4 billion and $1.9 billion, respectively. The reduction in balances with our subcustodian in Russia was a result of various actions taken re lated to our contractual arrangements that resulted in the derecognition of certain cash balances and related client liabilities. Cash and due from banks is evaluated as part of our allowance for credit losses.
Recent Accounting Developments	Recent Accounting Developments Relevant standards that were recently issued but not yet adopted as of September 30, 2024: Standard Description Effective Date Effects on the financial statements or other significant matters ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures The amendments related to the rate reconciliation and income taxes paid disclosures and require disclosures of (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. Additional amendments require (1) disclosures of pretax income (or loss) and income tax expense (or benefit) to be consistent with U.S. Securities and Exchange Commission regulations, and (2) remove disclosures that no longer are considered cost beneficial or relevant. Annual reporting for period ending December 31, 2025 We are currently evaluating the disclosure impact of the new standard. ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures The amendments enhance segment reporting by expanding the breadth and frequency of segment disclosures, including disclosure of (1) significant segment expenses, (2) other segment items, (3) the chief operating decision maker’s title and position and (4) how the chief operating decision maker uses the reported information to assess segment performance and how to allocate resources. The amendments also require these disclosures to be included in interim reporting. Annual reporting for period ending December 31, 2024 and for interim reporting in 2025 We are currently evaluating the disclosure impact of the new standard. Additionally, we continue to evaluate other accounting standards that were recently issued, but not yet adopted as of September 30, 2024; none are expected to have a material impact to our financial statements.
Fair Value Measurements	Fair Value Measurements We carry trading account assets and liabilities, AFS debt securities, certain equity securities and various types of derivative financial instruments, at fair value in our consolidated statement of condition on a recurring basis. Changes in the fair values of these financial assets and liabilities are recorded either as components of our consolidated statement of income or as components of AOCI within shareholders' equity in our consolidated statement of condition. We measure fair value for the above-described financial assets and liabilities in conformity with U.S. GAAP that governs the measurement of the fair value of financial instruments. Management believes that its valuation techniques and underlying assumptions used to measure fair value conform to the provisions of U.S. GAAP. We categorize the financial assets and liabilities that we carry at fair value based on a prescribed three-level valuation hierarchy. For information about our valuation techniques for financial assets and financial liabilities measured at fair value and the fair value hierarchy, refer to pages 134 to 139 in Note 2 to the consolidated financial statements included under Item 8, Financial Statements and Supplementary Data, in our 2023 Form 10-K.

(2) Under the advanced approaches, credit risk RWA includes a CVA which reflects the risk of potential fair value adjustments for credit risk reflected in our valuation of over-the-counter derivative contracts. We used a simple CVA approach in conformity with the Basel III advanced approaches. (3) Under the current advanced approaches rules and regulatory guidance concerning operational risk models, RWA attributable to operational risk can vary substantially from period-to-period, without direct correlation to the effects of a particular loss event on our results of operations and financial condition and impacting dates and periods that may differ from the dates and periods as of and during which the loss event is reflected in our financial statements, with the timing and categorization dependent on the processes for model updates and, if applicable, model revalidation and regulatory review and related supervisory processes. An individual loss event can have a significant effect on the output of our operational RWA under the advanced approaches depending on the severity of the loss event and its categorization among the seven Basel-defined UOMs. (4) Minimum requirements include a CCB of 2.5% and a SCB of 2.5% for the advanced approaches and the standardized approach, respectively, a G-SIB surcharge of 1.0% and a countercyclical buffer of 0%. On June 26, 2024, we were notified by the Federal Reserve of the results from the 2024 supervisory stress test. Our SCB calculated under the 2024 supervisory stress test was well below the 2.5% minimum, resulting in an SCB at that floor, which will continue to remain in effect from October 1, 2024, through September 30, 2025. (5) State Street Bank is required to maintain a minimum Tier 1 leverage ratio of 5% as it is the insured depository institution subsidiary of State Street Corporation, a U.S. G-SIB. NA

(2) Represents equity-based awards outstanding, but not included in the computation of diluted average common shares because their effect was anti-dilutive. Additional information about equity-based awards is provided on pages 171 to 173 in Note 18 to the consolidated financial statements included under Item 8, Financial Statements and Supplementary Data, in our 2023 Form 10-K. (3) Calculations reflect allocation of earnings to participating securities using the two-class method, as this computation is more dilutive than the treasury stock method.
