Organization, Consolidation and Presentation of Financial Statements [Abstract]
Introduction and Basis of Presentation	Introduction and Basis of Presentation The Firm Morgan Stanley is a global financial services firm that maintains significant market positions in each of its business segments—Institutional Securities, Wealth Management and Investment Management. Morgan Stanley, through its subsidiaries and affiliates, provides a wide variety of products and services to a large and diversified group of clients and customers, including corporations, governments, financial institutions and individuals. Unless the context otherwise requires, the terms “Morgan Stanley” or the “Firm” mean Morgan Stanley (the “Parent Company”) together with its consolidated subsidiaries. See the “Glossary of Common Terms and Acronyms” for the definition of certain terms and acronyms used throughout this Form 10-Q. A description of the clients and principal products and services of each of the Firm’s business segments is as follows: Institutional Securities provides a variety of products and services to corporations, governments, financial institutions and high to ultra-high net worth clients. Investment banking services consist of capital raising and financial advisory services, including services relating to the underwriting of debt, equity and other securities, as well as advice on mergers and acquisitions, restructurings, real estate and project finance. Our Equity and Fixed Income businesses include sales, financing, prime brokerage, market-making, Asia wealth management services and certain business-related investments. Lending activities include originating corporate loans and commercial real estate loans, providing secured lending facilities, and extending securities-based and other financing to customers. Other activities include research. Wealth Management provides a comprehensive array of financial services and solutions to individual investors and small to medium-sized businesses and institutions covering: financial advisor-led brokerage and investment advisory services; self-directed brokerage services, including through the E*TRADE platform; financial and wealth planning services; workplace services including stock plan administration; annuity and insurance products; securities-based lending, residential real estate loans and other lending products; banking; and retirement plan services. Investment Management provides a broad range of investment strategies and products that span geographies, asset classes, and public and private markets to a diverse group of clients across institutional and intermediary channels. Strategies and products, which are offered through a variety of investment vehicles, include equity, fixed income, alternatives and solutions, and liquidity and overlay services. Institutional clients include defined benefit/defined contribution plans, foundations, endowments, government entities, sovereign wealth funds, insurance companies, third-party fund sponsors and corporations. Individual clients are generally served through intermediaries, including affiliated and non-affiliated distributors. Basis of Financial Information The financial statements are prepared in accordance with U.S. GAAP, which requires the Firm to make estimates and assumptions regarding the valuations of certain financial instruments, the valuations of goodwill and intangible assets, the outcome of legal and tax matters, deferred tax assets, ACL, and other matters that affect its financial statements and related disclosures. The Firm believes that the estimates utilized in the preparation of its financial statements are prudent and reasonable. Actual results could differ materially from these estimates. The financial statements reflect the effects of the following reclassifications to prior period amounts. The Provision for credit losses for loans and lending commitments is now presented as a separate line in the income statements. Previously, the provision for credit losses for loans was included in Other revenues, and the provision for credit losses for lending commitments was included in Other expenses. In addition, economic hedges of certain held-for-sale and held-for-investment loans, which were previously reported in Trading revenues, are now reported in Other revenues. The Notes are an integral part of the Firm's financial statements. The Firm has evaluated subsequent events for adjustment to or disclosure in these financial statements through the date of this report and has not identified any recordable or disclosable events not otherwise reported in these financial statements or the notes thereto. The accompanying financial statements should be read in conjunction with the Firm’s financial statements and notes thereto included in the 2020 Form 10-K. Certain footnote disclosures included in the 2020 Form 10-K have been condensed or omitted from these financial statements as they are not required for interim reporting under U.S. GAAP. The financial statements reflect all adjustments of a normal, recurring nature that are, in the opinion of management, necessary for the fair presentation of the results for the interim period. The results of operations for interim periods are not necessarily indicative of results for the entire year. Consolidation The financial statements include the accounts of the Firm, its wholly owned subsidiaries and other entities in which the Firm has a controlling financial interest, including certain VIEs (see Note 15). Intercompany balances and transactions have been eliminated. For consolidated subsidiaries that are not wholly owned, the third-party holdings of equity interests are referred to as Noncontrolling interests. The net income attributable to Noncontrolling interests for such subsidiaries is presented as Net income applicable to noncontrolling interests in the income statements. The portion of shareholders’ equity that is attributable to noncontrolling interests for such subsidiaries is presented as noncontrolling interests, a component of Total equity, in the balance sheets. For a discussion of the Firm’s significant regulated U.S. and international subsidiaries and its involvement with VIEs, see Note 1 to the financial statements in the 2020 Form 10-K.

Business Combinations [Abstract]
Acquisitions	Acquisitions Acquisition of Eaton Vance On March 1, 2021, the Firm completed the acquisition of 100% of Eaton Vance in a stock and cash transaction, which increases the scale and breadth of the Investment Management business segment. Total consideration for the transaction was approximately $8.7 billion, which consists of the $5.3 billion fair value of 69 million common shares issued from Common stock held in treasury and cash of approximately $3.4 billion. Upon acquisition, the assets and liabilities of Eaton Vance were adjusted to their respective fair values as of the closing date of the transaction, including the identifiable intangible assets acquired. In addition, the excess of the purchase price over the fair value of the net assets acquired has been recorded as goodwill. The fair value estimates used in valuing certain acquired assets and liabilities are based, in part, on inputs that are unobservable. For intangible assets, these include, but are not limited to forecasted future cash flows, revenue growth rates, attrition rates and discount rates.

The proforma information does not reflect the potential benefits of cost and funding synergies, opportunities to earn additional revenues, or other factors, and therefore does not represent what the actual Net revenues and Net income would have been had the companies actually been combined as of this date.

For positions with the same counterparty that cross over the levels of the fair value hierarchy, both counterparty netting and cash collateral netting are included in the column titled “Netting.” Positions classified within the same level that are with the same counterparty are netted within that level. For further information on derivative instruments and hedging activities, see Note 7. 2. For a further breakdown by type, see the following Detail of Loans and Lending Commitments at Fair Value table. 3. For trading purposes, the Firm holds or sells short equity securities issued by entities in diverse industries and of varying sizes. 4. Amounts exclude certain investments that are measured based on NAV per share, which are not classified in the fair value hierarchy. For additional disclosure about such investments, see “Net Asset Value Measurements” herein.

Net transfers in the prior year quarter included the transfer of $857 million of equity margin loans from Level 2 to Level 3 as the significance of the margin loan rate input increased as a result of reduced liquidity. 2. Net transfers in the current quarter reflect the transfer of certain AFS securities from Level 3 to Level 2 due to increased trading activity and observability of pricing inputs. Level 3 instruments may be hedged with instruments classified in Level 1 and Level 2. The realized and unrealized gains or losses for assets and liabilities within the Level 3 category presented in the previous tables do not reflect the related realized and unrealized gains or losses on hedging instruments that have been classified by the Firm within the Level 1 and/or Level 2 categories. The unrealized gains (losses) during the period for assets and liabilities within the Level 3 category may include changes in fair value during the period that were attributable to both observable and unobservable inputs. Total realized and unrealized gains (losses) are primarily included in Trading revenues in the income statements. Additionally, in the previous tables, consolidations of VIEs are included in Purchases, and deconsolidations of VIEs are included in Settlements.

A single amount is disclosed for range and average when there is no significant difference between the minimum, maximum and average. Amounts represent weighted averages except where simple averages and the median of the inputs are more relevant. 2. Includes derivative contracts with multiple risks (i.e., hybrid products). The previous tables provide information on the valuation techniques, significant unobservable inputs, and the ranges and averages for each major category of assets and liabilities measured at fair value on a recurring and nonrecurring basis with a significant Level 3 balance. The level of aggregation and breadth of products cause the range of inputs to be wide and not evenly distributed across the inventory of financial instruments. Further, the range of unobservable inputs may differ across firms in the financial services industry because of diversity in the types of products included in each firm’s inventory. Generally, there are no predictable relationships between multiple significant unobservable inputs attributable to a given valuation technique. For a description of the Firm’s significant unobservable inputs and qualitative information about the effect of hypothetical changes in the values of those inputs, see Note 5 to the financial statements in the 2020 Form 10-K. During the current quarter, there were no significant revisions made to the descriptions of the Firm’s significant unobservable inputs.

Investments in hedge funds may be subject to initial period lock-up or gate provisions, which restrict an investor from withdrawing from the fund during a certain initial period or restrict the redemption amount on any redemption date, respectively. Amounts in the previous table represent the Firm’s carrying value of general and limited partnership interests in fund investments, as well as any related performance-based fees in the form of carried interest. The carrying amounts are measured based on the NAV of the fund taking into account the distribution terms applicable to the interest held. This same measurement applies whether the fund investments are accounted for under the equity method or fair value. For a description of the Firm’s investments in private equity funds, real estate funds and hedge funds, which are measured based on NAV, see Note 5 to the financial statements in the 2020 Form 10-K. See Note 14 for information regarding general partner guarantees, which include potential obligations to return performance fee distributions previously received. See Note 20 for information regarding unrealized carried interest at risk of reversal.

Gains and losses for Loans and Other assets—Other investments are classified in Other revenues. For other items, gains and losses are recorded in Other revenues if the item is held for sale; otherwise, they are recorded in Other expenses. 2. Nonrecurring changes in the fair value of loans and lending commitments were calculated as follows: for the held-for-investment category, based on the value of the underlying collateral; and for the held-for-sale category, based on recently executed transactions, market price quotations, valuation models that incorporate market observable inputs where possible, such as comparable loan or debt prices and CDS spread levels adjusted for any basis difference between cash and derivative instruments, or default recovery analysis where such transactions and quotations are unobservable. 3.

The allowance release was primarily a result of improvements in the outlook for macroeconomic conditions and the impact of paydowns on Corporate loans, including by lower-rated borrowers.The base scenario used in our ACL models as of March 31, 2021 was generated using a combination of industry consensus economic forecasts, forward rates, and internally developed and validated models. Given the nature of our lending portfolio, the most sensitive model input is U.S. gross domestic product. The base scenario, among other things, assumes a continued recovery over the forecast period with U.S. GDP reaching pre-COVID-19 levels by the third quarter of 2021, supported by fiscal stimulus and accommodative monetary policy.

See Note 15 for further information on other secured financings related to VIEs and securitization activities. For transfers of assets that fail to meet accounting criteria for a sale, the Firm continues to record the assets and recognizes the associated liabilities in the balance sheets.

These amounts include certain issued standby letters of credit participated to third parties, totaling $0.5 billion of notional and collateral/recourse, due to the nature of the Firm’s obligations under these arrangements. As of March 31, 2021, the carrying amount of standby letters of credit and other financial guarantees issued includes an allowance for credit losses of $73 million. 3. Primarily related to residential mortgage securitizations. The Firm has obligations under certain guarantee arrangements, including contracts and indemnification agreements, that contingently require the Firm to make payments to the guaranteed party based on changes in an underlying measure (such as an interest or foreign exchange rate, security or commodity price, an index, or the occurrence or non-occurrence of a specified event) related to an asset, liability or equity security of a guaranteed party. Also included as guarantees are contracts that contingently require the Firm to make payments to the guaranteed party based on another entity’s failure to perform under an agreement, as well as indirect guarantees of the indebtedness of others. For more information on the nature of the obligations and related business activities for our guarantees, see Note 15 to the financial statements in the 2020 Form 10-K. Other Guarantees and Indemnities In the normal course of business, the Firm provides guarantees and indemnifications in a variety of transactions. These provisions generally are standard contractual terms. Certain of these guarantees and indemnifications related to indemnities, exchange and clearinghouse member guarantees and merger and acquisition guarantees are described in Note 15 to the financial statements in the 2020 Form 10-K. In addition, in the ordinary course of business, the Firm guarantees the debt and/or certain trading obligations (including obligations associated with derivatives, foreign exchange contracts and the settlement of physical commodities) of certain subsidiaries. These guarantees generally are entity or product specific and are required by investors or trading counterparties. The activities of the Firm’s subsidiaries covered by these guarantees (including any related debt or trading obligations) are included in the financial statements. Finance Subsidiary The Parent Company fully and unconditionally guarantees the securities issued by Morgan Stanley Finance LLC, a wholly owned finance subsidiary. No other subsidiary of the Parent Company guarantees these securities. Contingencies Legal In addition to the matters described in the following paragraphs, in the normal course of business, the Firm has been named, from time to time, as a defendant in various legal actions, including arbitrations, class actions and other litigation, arising in connection with its activities as a global diversified financial services institution. Certain of the actual or threatened legal actions include claims for substantial compensatory and/or punitive damages or claims for indeterminate amounts of damages. In some cases, the entities that would otherwise be the primary defendants in such cases are bankrupt or are in financial distress. These actions have included, but are not limited to, residential mortgage and credit crisis-related matters. While the Firm has identified below any individual proceedings where the Firm believes a material loss to be reasonably possible and reasonably estimable, there can be no assurance that material losses will not be incurred from claims that have not yet been asserted or those where potential losses have not yet been determined to be probable or possible, and reasonably estimable. The Firm contests liability and/or the amount of damages as appropriate in each pending matter. Where available information indicates that it is probable a liability had been incurred at the date of the financial statements and the Firm can reasonably estimate the amount of that loss, the Firm accrues the estimated loss by a charge to income. In many proceedings and investigations, however, it is inherently difficult to determine whether any loss is probable or even possible or to estimate the amount of any loss. In addition, even where a loss is possible or an exposure to loss exists in excess of the liability already accrued with respect to a previously recognized loss contingency, it is not always possible to reasonably estimate the size of the possible loss or range of loss, particularly for proceedings and investigations where the factual record is being developed or contested or where plaintiffs or government entities seek substantial or indeterminate damages, restitution, disgorgement or penalties. Numerous issues may need to be resolved before a loss or additional loss, or range of loss or additional range of loss, can be reasonably estimated for a proceeding or investigation, including through potentially lengthy discovery and determination of important factual matters, determination of issues related to class certification and the calculation of damages or other relief, and by addressing novel or unsettled legal questions relevant to the proceedings or investigations in question. For certain other legal proceedings and investigations, the Firm can estimate reasonably possible losses, additional losses, ranges of loss or ranges of additional loss in excess of amounts accrued but does not believe, based on current knowledge and after consultation with counsel, that such losses could have a material adverse effect on the Firm’s financial statements as a whole, other than the matters referred to in the following paragraphs. On September 23, 2014, Financial Guaranty Insurance Company (“FGIC”) filed a complaint against the Firm in the Supreme Court of the State of New York County (“Supreme Court of NY”) styled Financial Guaranty Insurance Company v. Morgan Stanley ABS Capital I Inc. et al . relating to the Morgan Stanley ABS Capital I Inc. Trust 2007-NC4. The complaint asserts claims for breach of contract and fraudulent inducement and alleges, among other things, that the loans in the trust breached various representations and warranties and defendants made untrue statements and material omissions to induce FGIC to issue a financial guaranty policy on certain classes of certificates that had an original balance of approximately $876 million. The complaint seeks, among other relief, specific performance of the loan breach remedy procedures in the transaction documents, compensatory, consequential and punitive damages, attorneys’ fees, interest and costs. On January 23, 2017, the court denied the Firm’s motion to dismiss the complaint. On September 13, 2018, the Appellate Division, First Department (“First Department”) affirmed in part and reversed in part the lower court’s order denying the Firm’s motion to dismiss the complaint. On December 20, 2018, the First Department denied plaintiff’s motion for leave to appeal to the New York Court of Appeals (“Court of Appeals”) or, in the alternative, for re-argument. Based on currently available information, the Firm believes that it could incur a loss in this action of up to approximately $277 million, the total original unpaid balance of the mortgage loans for which the Firm received repurchase demands from a certificate holder and FGIC that the Firm did not repurchase, plus pre- and post- judgment interest, fees and costs, as well as claim payments that FGIC has made and will make in the future. In addition, plaintiff is seeking to expand the number of loans at issue and the possible range of loss could increase. On January 23, 2015, Deutsche Bank National Trust Company, in its capacity as trustee, filed a complaint against the Firm styled Deutsche Bank National Trust Company solely in its capacity as Trustee of the Morgan Stanley ABS Capital I Inc. Trust 2007-NC4 v. Morgan Stanley Mortgage Capital Holdings LLC as Successor-by-Merger to Morgan Stanley Mortgage Capital Inc., and Morgan Stanley ABS Capital I Inc. , pending in the Supreme Court of NY. The complaint asserts claims for breach of contract and alleges, among other things, that the loans in the trust, which had an original principal balance of approximately $1.05 billion, breached various representations and warranties. The complaint seeks, among other relief, specific performance of the loan breach remedy procedures in the transaction documents, compensatory, consequential, rescissory, equitable and punitive damages, attorneys’ fees, costs and other related expenses, and interest. On December 11, 2015, the court granted in part and denied in part the Firm’s motion to dismiss the complaint. On October 19, 2018, the court granted the Firm’s motion for leave to amend its answer and to stay the case pending resolution of Deutsche Bank National Trust Company’s appeal to the Court of Appeals in another case, styled Deutsche Bank National Trust Company v. Barclays Bank PLC , regarding the applicable statute of limitations. On January 17, 2019, the First Department reversed the trial court’s order to the extent that it had granted in part the Firm’s motion to dismiss the complaint. On June 4, 2019, the First Department granted the Firm’s motion for leave to appeal its January 17, 2019 decision to the Court of Appeals. On March 19, 2020, the Firm filed a motion for partial summary judgment. Based on currently available information, the Firm believes that it could incur a loss in this action of up to approximately $277 million, the total original unpaid balance of the mortgage loans for which the Firm received repurchase demands from a certificate holder and a monoline insurer that the Firm did not repurchase, plus pre- and post-judgment interest, fees and costs, but plaintiff is seeking to expand the number of loans at issue and the possible range of loss could increase. Tax In matters styled Case number 15/3637 and Case number 15/4353 , the Dutch Tax Authority (“Dutch Authority”) is challenging in the Dutch courts, the prior set-off by the Firm of approximately €124 million (approximately $145 million) plus accrued interest of withholding tax credits against the Firm’s corporation tax liabilities for the tax years 2007 to 2013. The Dutch Authority alleges that the Firm was not entitled to receive the withholding tax credits on the basis, inter alia, that a Firm subsidiary did not hold legal title to certain securities subject to withholding tax on the relevant dates. The Dutch Authority has also alleged that the Firm failed to provide certain information to the Dutch Authority and keep adequate books and records. On April 26, 2018, the District Court in Amsterdam issued a decision dismissing the Dutch Authority’s claims with respect to certain of the tax years in dispute. On May 12, 2020, the Court of Appeal in Amsterdam granted the Dutch Authority’s appeal in matters re-styled Case number 18/00318 and Case number 18/00319 . On June 22, 2020, the Firm filed an appeal against the decision of the Court of Appeal in Amsterdam before the Dutch High Court. On January 29, 2021, the Advocate General of the Dutch High Court in matters re-styled Case number 15/3637 and Case number 15/4353

Generally, most assets owned by consolidated VIEs cannot be removed unilaterally by the Firm and are not available to the Firm while the related liabilities issued by consolidated VIEs are non-recourse to the Firm. However, in certain consolidated VIEs, the Firm either has the unilateral right to remove assets or provides additional recourse through derivatives such as total return swaps, guarantees or other forms of involvement. In general, the Firm’s exposure to loss in consolidated VIEs is limited to losses that would be absorbed on the VIE net assets recognized in its financial statements, net of amounts absorbed by third-party variable interest holders.

Where notional amounts are utilized in quantifying the maximum exposure related to derivatives, such amounts do not reflect changes in fair value recorded by the Firm. 4. Additional VIE assets owned represents the carrying value of total exposure to non-consolidated VIEs for which the maximum exposure to loss is less than specific thresholds, primarily interests issued by securitization SPEs. The Firm’s maximum exposure to loss generally equals the fair value of the assets owned. These assets are primarily included in Trading assets and Investment securities and are measured at fair value (see Note 5). The Firm does not provide additional support in these transactions through contractual facilities, guarantees or similar derivatives. The majority of the VIEs included in the previous tables are sponsored by unrelated parties; examples of the Firm’s involvement with these VIEs include its secondary market-making activities and the securities held in its Investment securities portfolio (see Note 8). The Firm’s maximum exposure to loss is dependent on the nature of the Firm’s variable interest in the VIE and is limited to the notional amounts of certain liquidity facilities and other credit support, total return swaps and written put options, as well as the fair value of certain other derivatives and investments the Firm has made in the VIE. The Firm’s maximum exposure to loss in the previous tables does not include the offsetting benefit of hedges or any reductions associated with the amount of collateral held as part of a transaction with the VIE or any party to the VIE directly against a specific exposure to loss. Liabilities issued by VIEs generally are non-recourse to the Firm.

The previous tables include transactions with SPEs in which the Firm, acting as principal, transferred financial assets with continuing involvement and received sales treatment. The transferred assets are carried at fair value prior to securitization, and any changes in fair value are recognized in the income statements. The Firm may act as underwriter of the beneficial interests issued by these securitization vehicles, for which Investment banking revenues are recognized. The Firm may retain interests in the securitized financial assets as one or more tranches of the securitization. These retained interests are generally carried at fair value in the balance sheets with changes in fair value recognized in the income statements. Fair value for these interests is measured using techniques that are consistent with the valuation techniques applied to the Firm’s major categories of assets and liabilities as described in Note 2 in the 2020 Form 10-K and Note 5 herein.

Brokers and Dealers [Abstract]
Regulatory Requirements	Regulatory Requirements Regulatory Capital Framework and Requirements For a discussion of the Firm’s regulatory capital framework, see Note 17 to the financial statements in the 2020 Form 10-K. The Firm is required to maintain minimum risk-based and leverage-based capital ratios under regulatory capital requirements. A summary of the calculations of regulatory capital and RWA follows. Minimum risk-based capital ratio requirements apply to Common Equity Tier 1 capital, Tier 1 capital and Total capital (which includes Tier 2 capital). Capital standards require certain adjustments to, and deductions from, capital for purposes of determining these ratios. At March 31, 2021 and December 31, 2020, the difference between the actual and required ratio was lower under the Standardized Approach. In 2020, the U.S. banking agencies adopted a final rule, consistent with an interim final rule that was effective March 31, 2020, altering, for purposes of the regulatory capital rules, the required adoption time period for CECL. As of March 31, 2021 and December 31, 2020, the risk-based and leverage-based capital amounts and ratios, as well as RWA, adjusted average assets and supplementary leverage exposure are calculated excluding the effect of the adoption of CECL based on the Firm’s election to defer this effect over a five-year transition period in accordance with the final rule. Risk-Based Regulatory Capital Ratio Requirements At March 31, 2021 and December 31, 2020 Standardized Advanced Capital buffers Capital conservation buffer — 2.5% SCB 5.7% N/A G-SIB capital surcharge 3.0% 3.0% CCyB 1 0% 0% Capital buffer requirement 2 8.7% 5.5% At March 31, 2021 and December 31, 2020 Regulatory Minimum Standardized Advanced Required ratios 3 Common Equity Tier 1 capital ratio 4.5 % 13.2% 10.0% Tier 1 capital ratio 6.0 % 14.7% 11.5% Total capital ratio 8.0 % 16.7% 13.5% 1. The CCyB can be set up to 2.5%, but is currently set by the U.S. banking agencies at zero. 2. The capital buffer requirement represents the amount of Common Equity Tier 1 capital the Firm must maintain above the minimum risk-based capital requirements in order to avoid restrictions on the Firm's ability to make capital distributions, including the payment of dividends and the repurchase of stock, and to pay discretionary bonuses to executive officers. The Firm's Standardized Approach capital buffer requirement is equal to the sum of the SCB, G-SIB capital surcharge and CCyB, and the Advanced Approach capital buffer requirement is equal to the 2.5% capital conservation buffer, G-SIB capital surcharge and CCyB. 3. Required ratios represent the regulatory minimum plus the capital buffer requirement. The Firm’s Regulatory Capital and Capital Ratios At March 31, 2021 $ in millions Required 1 Amount Ratio Risk-based capital Common Equity Tier 1 capital 13.2 % $ 76,176 16.7 % Tier 1 capital 14.7 % 84,059 18.5 % Total capital 16.7 % 92,823 20.4 % Total RWA 455,071 $ in millions Required Ratio 1 At Leverage-based capital Adjusted average assets 2 $ 1,121,413 Tier 1 leverage ratio 4.0 % 7.5 % Supplementary leverage exposure 3,4 $ 1,263,959 SLR 4 5.0 % 6.7 % At December 31, 2020 $ in millions Required Ratio 1 Amount Ratio Risk-based capital Common Equity Tier 1 capital 13.2 % $ 78,650 17.4 % Tier 1 capital 14.7 % 88,079 19.4 % Total capital 16.7 % 97,213 21.5 % Total RWA 453,106 $ in millions Required Ratio 1 At Leverage-based capital Adjusted average assets 2 $ 1,053,510 Tier 1 leverage ratio 4.0 % 8.4 % Supplementary leverage exposure 3,4 $ 1,192,506 SLR 4 5.0 % 7.4 % 1. Required ratios are inclusive of any buffers applicable as of the date presented. Failure to maintain the buffers would result in restrictions on the Firm’s ability to make capital distributions, including the payment of dividends and the repurchase of stock, and to pay discretionary bonuses to executive officers. 2. Adjusted average assets represents the denominator of the Tier 1 leverage ratio and is composed of the average daily balance of consolidated on-balance sheet assets for the quarters ending on the respective balance sheet dates, reduced by disallowed goodwill, intangible assets, investments in covered funds, defined benefit pension plan assets, after-tax gain on sale from assets sold into securitizations, investments in the Firm’s own capital instruments, certain defined tax assets and other capital deductions. 3. Supplementary leverage exposure is the sum of Adjusted average assets used in the Tier 1 leverage ratio and other adjustments, primarily: (i) for derivatives, potential future exposure and the effective notional principal amount of sold credit protection offset by qualifying purchased credit protection; (ii) the counterparty credit risk for repo-style transactions; and (iii) the credit equivalent amount for off-balance sheet exposures. 4. Based on a Federal Reserve interim final rule that was in effect until March 31, 2021, the Firm’s SLR and Supplementary leverage exposure as of March 31, 2021 and December 31, 2020 reflect the exclusion of U.S. Treasury securities and deposits at Federal Reserve Banks. Certain U.S. Bank Subsidiaries’ Regulatory Capital and Capital Ratios The OCC establishes capital requirements for the Firm’s U.S. bank subsidiaries, which as of March 31, 2021 and December 31, 2020 include, among others, Morgan Stanley Bank, N.A. (“MSBNA”) and Morgan Stanley Private Bank, National Association (“MSPBNA”), and evaluates their compliance with such capital requirements. Regulatory capital requirements for MSBNA and MSPBNA are calculated in a similar manner to the Firm’s regulatory capital requirements, although G-SIB capital surcharge and SCB requirements do not apply to the U.S. bank subsidiaries. The OCC’s regulatory capital framework includes Prompt Corrective Action (“PCA”) standards, including “well-capitalized” PCA standards that are based on specified regulatory capital ratio minimums. For the Firm to remain an FHC, its U.S. bank subsidiaries must remain well-capitalized in accordance with the OCC’s PCA standards. In addition, failure by the U.S. bank subsidiaries to meet minimum capital requirements may result in certain mandatory and discretionary actions by regulators that, if undertaken, could have a direct material effect on the U.S. bank subsidiaries’ and the Firm’s financial statements. At March 31, 2021 and December 31, 2020, MSBNA and MSPBNA risk-based capital ratios are based on the Standardized Approach rules. At March 31, 2021 and December 31, 2020, the risk-based and leverage-based capital amounts and ratios are calculated excluding the effect of the adoption of CECL based on MSBNA’s and MSPBNA’s election to defer this effect over a five-year transition period.

MS&Co. has consistently operated with capital in excess of its regulatory capital requirements. As an Alternative Net Capital broker-dealer, and in accordance with Securities Exchange Act of 1934 (“Exchange Act”) Rule 15c3-1, Appendix E, MS&Co. is subject to minimum net capital and tentative net capital requirements. In addition, MS&Co. must notify the SEC if its tentative net capital falls below certain levels. At March 31, 2021 and December 31, 2020, MS&Co. exceeded its net capital requirement and had tentative net capital in excess of the minimum and notification requirements. Other Regulated Subsidiaries MSSB, a registered U.S. broker-dealer and introducing broker for the futures business, is subject to the minimum net capital requirements of the SEC. MSIP, a London-based broker-dealer subsidiary, is subject to the capital requirements of the PRA, and the Morgan Stanley Europe Holdings SE Group (“MSEHSE Group”) is subject to the capital requirements of the European Central Bank, BaFin and the German Central Bank. MSSB, MSIP and the MSEHSE Group, including MSESE, a Germany-based broker-dealer, have consistently operated with capital in excess of their respective regulatory capital requirements. Additionally, E*TRADE Bank and E*TRADE Savings Bank are subject to the capital requirements of the OCC, and E*TRADE Securities LLC is subject to the minimum net capital requirements of the SEC; each of these entities has consistently operated with capital in excess of their respective regulatory capital requirements.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Firm is under continuous examination by the IRS and other tax authorities in certain countries, such as Japan and the U.K., and in states and localities in which it has significant business operations, such as New York. The Firm believes that the resolution of these tax examinations will not have a material effect on the annual financial statements, although a resolution could have a material impact in the income statement and on the effective tax rate for any period in which such resolutions occur. It is reasonably possible that significant changes in the balance of unrecognized tax benefits may occur within the next 12 months. At this time, however, it is not possible to reasonably estimate the expected change to the total amount of unrecognized tax benefits and the impact on the Firm’s effective tax rate over the next 12 months.

Basis of Financial Information	Basis of Financial Information The financial statements are prepared in accordance with U.S. GAAP, which requires the Firm to make estimates and assumptions regarding the valuations of certain financial instruments, the valuations of goodwill and intangible assets, the outcome of legal and tax matters, deferred tax assets, ACL, and other matters that affect its financial statements and related disclosures. The Firm believes that the estimates utilized in the preparation of its financial statements are prudent and reasonable. Actual results could differ materially from these estimates. The financial statements reflect the effects of the following reclassifications to prior period amounts. The Provision for credit losses for loans and lending commitments is now presented as a separate line in the income statements. Previously, the provision for credit losses for loans was included in Other revenues, and the provision for credit losses for lending commitments was included in Other expenses. In addition, economic hedges of certain held-for-sale and held-for-investment loans, which were previously reported in Trading revenues, are now reported in Other revenues. The Notes are an integral part of the Firm's financial statements. The Firm has evaluated subsequent events for adjustment to or disclosure in these financial statements through the date of this report and has not identified any recordable or disclosable events not otherwise reported in these financial statements or the notes thereto. The accompanying financial statements should be read in conjunction with the Firm’s financial statements and notes thereto included in the 2020 Form 10-K. Certain footnote disclosures included in the 2020 Form 10-K have been condensed or omitted from these financial statements as they are not required for interim reporting under U.S. GAAP. The financial statements reflect all adjustments of a normal, recurring nature that are, in the opinion of management, necessary for the fair presentation of the results for the interim period. The results of operations for interim periods are not necessarily indicative of results for the entire year.
Consolidation	Consolidation The financial statements include the accounts of the Firm, its wholly owned subsidiaries and other entities in which the Firm has a controlling financial interest, including certain VIEs (see Note 15). Intercompany balances and transactions have been eliminated. For consolidated subsidiaries that are not wholly owned, the third-party holdings of equity interests are referred to as Noncontrolling interests. The net income attributable to Noncontrolling interests for such subsidiaries is presented as Net income applicable to noncontrolling interests in the income statements. The portion of shareholders’ equity that is attributable to noncontrolling interests for such subsidiaries is presented as noncontrolling interests, a component of Total equity, in the balance sheets. For a discussion of the Firm’s significant regulated U.S. and international subsidiaries and its involvement with VIEs, see Note 1 to the financial statements in the 2020 Form 10-K.

The CCyB can be set up to 2.5%, but is currently set by the U.S. banking agencies at zero. 2. The capital buffer requirement represents the amount of Common Equity Tier 1 capital the Firm must maintain above the minimum risk-based capital requirements in order to avoid restrictions on the Firm's ability to make capital distributions, including the payment of dividends and the repurchase of stock, and to pay discretionary bonuses to executive officers. The Firm's Standardized Approach capital buffer requirement is equal to the sum of the SCB, G-SIB capital surcharge and CCyB, and the Advanced Approach capital buffer requirement is equal to the 2.5% capital conservation buffer, G-SIB capital surcharge and CCyB. 3. Required ratios represent the regulatory minimum plus the capital buffer requirement.

Required ratios are inclusive of any buffers applicable as of the date presented. Failure to maintain the buffers would result in restrictions on the Firm’s ability to make capital distributions, including the payment of dividends and the repurchase of stock, and to pay discretionary bonuses to executive officers. 2. Adjusted average assets represents the denominator of the Tier 1 leverage ratio and is composed of the average daily balance of consolidated on-balance sheet assets for the quarters ending on the respective balance sheet dates, reduced by disallowed goodwill, intangible assets, investments in covered funds, defined benefit pension plan assets, after-tax gain on sale from assets sold into securitizations, investments in the Firm’s own capital instruments, certain defined tax assets and other capital deductions. 3. Supplementary leverage exposure is the sum of Adjusted average assets used in the Tier 1 leverage ratio and other adjustments, primarily: (i) for derivatives, potential future exposure and the effective notional principal amount of sold credit protection offset by qualifying purchased credit protection; (ii) the counterparty credit risk for repo-style transactions; and (iii) the credit equivalent amount for off-balance sheet exposures. 4. Based on a Federal Reserve interim final rule that was in effect until March 31, 2021, the Firm’s SLR and Supplementary leverage exposure as of March 31, 2021 and December 31, 2020 reflect the exclusion of U.S. Treasury securities and deposits at Federal Reserve Banks.
