Accounting Policies [Abstract]
Basis of Presentation and Accounting Policies	BASIS OF PRESENTATION AND ACCOUNTING POLICIES Organization The accompanying unaudited consolidated financial statements were prepared in accordance with United States (U.S.) generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, the statements do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation were included. The results of operations for the nine months ended September 30, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022. Certain items in prior periods were reclassified to conform to the current presentation. For further information, refer to the consolidated financial statements and footnotes thereto included in the Annual Report of Comerica Incorporated and Subsidiaries (the Corporation) on Form 10-K for the year ended December 31, 2021. Recently Issued Accounting Pronouncements In March 2022, the FASB issued ASU No. 2022-02, “Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructuring and Vintage Disclosures” (ASU 2022-02), which eliminates the accounting for troubled debt restructuring (TDR) while expanding modification and vintage disclosure requirements. Under the current guidance, a TDR occurs when a loan to a borrower experiencing financial difficulty is restructured with a concession provided that a creditor would not otherwise consider. ASU 2022-02 removes the TDR accounting model, instead requiring modifications to apply existing refinancing and restructuring guidance. The update also requires additional disclosures on the nature, magnitude and subsequent performance of certain types of modifications with borrowers experiencing financial difficulties. ASU 2022-02 further included a requirement to disclose gross charge-offs incurred by year of origination of the related loan or lease. ASU 2022-02 is effective for the Corporation on January 1, 2023, and must be applied prospectively, except that the recognition and measurement of TDRs may be applied using a modified retrospective approach. Early adoption is permitted. The Corporation is evaluating the impact of the new guidance to its disclosures but does not expect there to be a material impact on its financial condition or results of operation.

Fair Value Measurements

Fair Value Measurements	9 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS The Corporation utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The determination of fair values of financial instruments often requires the use of estimates. In cases where quoted market values in an active market are not available, the Corporation uses present value techniques and other valuation methods to estimate the fair values of its financial instruments. These valuation methods require considerable judgment and the resulting estimates of fair value can be significantly affected by the assumptions made and methods used. Investment securities available-for-sale, derivatives, deferred compensation plans and equity securities with readily determinable fair values (primarily money market mutual funds) are recorded at fair value on a recurring basis. Additionally, from time to time, the Corporation may be required to record other assets and liabilities at fair value on a nonrecurring basis, such as impaired loans, other real estate (primarily foreclosed property), nonmarketable equity securities and certain other assets and liabilities. These nonrecurring fair value adjustments typically involve write-downs of individual assets or application of lower of cost or fair value accounting. Refer to Note 1 to the consolidated financial statements in the Corporation's Annual Report on Form 10-K for the year ended December 31, 2021 for further information about the fair value hierarchy, descriptions of the valuation methodologies and key inputs used to measure financial assets and liabilities recorded at fair value, as well as a description of the methods and significant assumptions used to estimate fair value disclosures for financial instruments not recorded at fair value in their entirety on a recurring basis. Assets and Liabilities Recorded at Fair Value on a Recurring Basis The following tables present the recorded amount of assets and liabilities measured at fair value on a recurring basis as of September 30, 2022 and December 31, 2021.

There were no transfers of assets or liabilities recorded at fair value on a recurring basis into or out of Level 3 fair value measurements during each of the three- and nine-month periods ended September 30, 2022 and 2021. The following table summarizes the changes in Level 3 assets and liabilities measured at fair value on a recurring basis for the three- and nine-month periods ended September 30, 2022 and 2021.

Assets and Liabilities Recorded at Fair Value on a Nonrecurring Basis The Corporation may be required to record certain assets and liabilities at fair value on a nonrecurring basis. These include assets that are recorded at the lower of cost or fair value, and were recognized at fair value since it was less than cost at the end of the period. The following table presents assets recorded at fair value on a nonrecurring basis at September 30, 2022 and December 31, 2021. No liabilities were recorded at fair value on a nonrecurring basis at September 30, 2022 and December 31, 2021. (in millions) Level 3 September 30, 2022 Loans: Commercial $ 53 Real estate construction 2 Commercial mortgage 14 Total assets at fair value $ 69 December 31, 2021 Loans: Commercial $ 125 Real estate construction 4 Commercial mortgage 17 International 4 Total assets at fair value $ 150 Level 3 assets recorded at fair value on a nonrecurring basis at September 30, 2022 and December 31, 2021 included both nonaccrual loans and TDRs for which a specific allowance was established based on the fair value of collateral. The unobservable inputs were the additional adjustments applied by management to the appraised values to reflect such factors as non-current appraisals and revisions to estimated time to sell. These adjustments are determined based on qualitative judgments made by management on a case-by-case basis and are not observable inputs, although they are used in the determination of fair value. Estimated Fair Values of Financial Instruments Not Recorded at Fair Value on a Recurring Basis The Corporation typically holds the majority of its financial instruments until maturity and thus does not expect to realize many of the estimated fair value amounts disclosed. The disclosures also do not include estimated fair value amounts for items that are not defined as financial instruments, but which have significant value. These include such items as core deposit intangibles, the future earnings potential of significant customer relationships and the value of trust operations and other fee generating businesses.

A summary of the Corporation’s investment securities in an unrealized loss position as of September 30, 2022 and December 31, 2021 follows: Less than 12 Months 12 Months or more Total (in millions) Fair Unrealized Fair Unrealized Fair Unrealized September 30, 2022 U.S. Treasury securities $ 1,093 $ 8 $ 1,663 $ 154 $ 2,756 $ 162 Residential mortgage-backed securities (a) 7,648 1,157 4,398 1,181 12,046 2,338 Commercial mortgage-backed securities (a) 4,477 564 167 43 4,644 607 Total temporarily impaired securities $ 13,218 $ 1,729 $ 6,228 $ 1,378 $ 19,446 $ 3,107 December 31, 2021 U.S. Treasury securities $ 465 $ 6 $ 1,334 $ 33 $ 1,799 $ 39 Residential mortgage-backed securities (a) 7,197 128 1,128 48 8,325 176 Commercial mortgage-backed securities (a) 346 6 — — 346 6 Total temporarily impaired securities $ 8,008 $ 140 $ 2,462 $ 81 $ 10,470 $ 221 (a) Issued and/or guaranteed by U.S. government agencies or U.S. government-sponsored enterprises. Unrealized losses on investment securities resulted from changes in market interest rates. The Corporation’s portfolio is comprised of securities issued or guaranteed by the U.S. government or government-sponsored enterprises. As such, it is expected that the securities would not be settled at a price less than the amortized cost of the investments. Further, the Corporation does not intend to sell the investments, and it is not more likely than not that it will be required to sell the investments before recovery of amortized costs. At September 30, 2022, the Corporation had 1,290 securities in an unrealized loss position with no allowance for credit losses, comprised of 28 U.S. Treasury securities, 1,008 residential mortgage-backed securities and 254 commercial mortgage-backed securities. Interest receivable on investment securities totaled $48 million at September 30, 2022 and $36 million at December 31, 2021 and was included in accrued income and other assets on the Consolidated Balance Sheets. Sales, calls and write-downs of investment securities available-for-sale, computed based on the adjusted cost of the specific security, resulted in no gains or losses during the three months ended and nine months ended September 30, 2022 or September 30, 2021. The following table summarizes the amortized cost and fair values of investment securities by contractual maturity. Securities with multiple maturity dates are classified in the period of final maturity. The actual cash flows of mortgage-backed securities may differ as borrowers of the underlying loans may exercise prepayment options. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

(b) Includes Small Business Administration Paycheck Protection Program (PPP) loans of $46 million and $458 million at September 30, 2022 and December 31, 2021, respectively. (c) Includes loans with an internal rating of special mention, substandard loans for which the accrual of interest has not been discontinued and nonaccrual loans. Special mention loans have potential credit weaknesses that deserve management’s close attention, such as loans to borrowers who may be experiencing financial difficulties that may result in deterioration of repayment prospects from the borrower at some future date. Accruing substandard loans have a well-defined weakness, or weaknesses, such as loans to borrowers who may be experiencing losses from operations or inadequate liquidity of a degree and duration that jeopardizes the orderly repayment of the loan. Substandard loans are also distinguished by the distinct possibility of loss in the future if these weaknesses are not corrected. Nonaccrual loans are loans for which the accrual of interest has been discontinued. For further information regarding nonaccrual loans, refer to the Nonperforming Assets subheading in Note 1 - Basis of Presentation and Accounting Policies on page F-52 in the Corporation's 2021 Annual Report. These categories are generally consistent with the "special mention" and "substandard" categories as defined by regulatory authorities. A minority of nonaccrual loans are consistent with the "doubtful" category. Loan interest receivable totaled $202 million and $120 million at September 30, 2022 and December 31, 2021, respectively and was included in accrued income and other assets on the Consolidated Balance Sheets.

On an ongoing basis, the Corporation monitors the performance of modified loans to their restructured terms. The allowance for loan losses continues to be reassessed on the basis of an individual evaluation of the loan.

These financial instruments involve, to varying degrees, elements of market and credit risk. Market and credit risk are included in the determination of fair value. Market risk is the potential loss that may result from movements in interest rates, foreign currency exchange rates or energy commodity prices that cause an unfavorable change in the value of a financial instrument. The Corporation manages this risk by establishing monetary exposure limits and monitoring compliance with those limits. Market risk inherent in interest rate and energy contracts entered into on behalf of customers is mitigated by taking offsetting positions, except in those circumstances when the amount, tenor and/or contract rate level results in negligible economic risk, whereby the cost of purchasing an offsetting contract is not economically justifiable. The Corporation mitigates most of the inherent market risk in foreign exchange contracts entered into on behalf of customers by taking offsetting positions and manages the remainder through individual foreign currency position limits and aggregate value-at-risk limits. These limits are established annually and positions are monitored quarterly. Market risk inherent in derivative instruments held or issued for risk management purposes is typically offset by changes in the fair value of the assets or liabilities being hedged. Credit risk is the possible loss that may occur in the event of nonperformance by the counterparty to a financial instrument. The Corporation attempts to minimize credit risk arising from customer-initiated derivatives by evaluating the creditworthiness of each customer, adhering to the same credit approval process used for traditional lending activities and obtaining collateral as deemed necessary. Derivatives with dealer counterparties are either cleared through a clearinghouse or settled directly with a single counterparty. For derivatives settled directly with dealer counterparties, the Corporation utilizes counterparty risk limits and monitoring procedures as well as master netting arrangements and bilateral collateral agreements to facilitate the management of credit risk. Included in the fair value of derivative instruments are credit valuation adjustments reflecting counterparty credit risk. These adjustments are determined by applying a credit spread for the counterparty or the Corporation, as appropriate, to the total expected exposure of the derivative. Master netting arrangements effectively reduce credit valuation adjustments by permitting settlement of positive and negative positions and offset cash collateral held with the same counterparty on a net basis. Bilateral collateral agreements require daily exchange of cash or highly rated securities issued by the U.S. Treasury or other U.S. government entities to collateralize amounts due to either party. At September 30, 2022, counterparties with bilateral collateral agreements deposited $196 million of cash with the Corporation to secure the fair value of contracts in an unrealized gain position, and the Corporation had pledged $127 million of marketable investment securities and posted $280 million of cash as collateral for contracts in an unrealized loss position. For those counterparties not covered under bilateral collateral agreements, collateral is obtained, if deemed necessary, based on the results of management’s credit evaluation of the counterparty. Collateral varies, but may include cash, investment securities, accounts receivable, equipment or real estate. Derivative Instruments Derivative instruments utilized by the Corporation are negotiated over-the-counter and primarily include swaps, caps and floors, forward contracts and options, each of which may relate to interest rates, energy commodity prices or foreign currency exchange rates. Swaps are agreements in which two parties periodically exchange cash payments based on specified indices applied to a specified notional amount until a stated maturity. Caps and floors are agreements which entitle the buyer to receive cash payments based on the difference between a specified reference rate or price and an agreed strike rate or price, applied to a specified notional amount until a stated maturity. Forward contracts are over-the-counter agreements to buy or sell an asset at a specified future date and price. Options are similar to forward contracts except the purchaser has the right, but not the obligation, to buy or sell the asset during a specified period or at a specified future date. Over-the-counter contracts are tailored to meet the needs of the counterparties involved and, therefore, contain a greater degree of credit risk and liquidity risk than exchange-traded contracts, which have standardized terms and readily available price information. The Corporation reduces exposure to market and liquidity risks from over-the-counter derivative instruments entered into for risk management purposes, and transactions entered into to mitigate the market risk associated with customer-initiated transactions, by taking offsetting positions with investment grade domestic and foreign financial institutions and subjecting counterparties to credit approvals, limits and collateral monitoring procedures similar to those used in making other extensions of credit. In addition, certain derivative contracts executed bilaterally with a dealer counterparty in the over-the-counter market are cleared through a clearinghouse, whereby the clearinghouse becomes the counterparty to the transaction. The following table presents the composition of the Corporation’s derivative instruments held or issued for risk management purposes or in connection with customer-initiated and other activities at September 30, 2022 and December 31, 2021. The table excludes a derivative related to the Corporation's 2008 sale of its remaining ownership of Visa shares and includes accrued interest receivable and payable.

These amounts are typically not exchanged, significantly exceed amounts subject to credit or market risk and are not reflected in the Consolidated Balance Sheets. (b) September 30, 2022 included $10.8 billion of forward starting swaps that will become effective on their contractual start dates in 2022, 2023 and 2024. (c) Net derivative assets are included in accrued income and other assets and net derivative liabilities are included in accrued expenses and other liabilities on the Consolidated Balance Sheets. Included in the fair value of net derivative assets and net derivative liabilities are credit valuation adjustments reflecting counterparty credit risk and credit risk of the Corporation. The fair value of net derivative assets included credit valuation adjustments for counterparty credit risk of $3 million and $9 million at September 30, 2022 and December 31, 2021, respectively. Risk Management The Corporation's derivative instruments used for managing interest rate risk include cash flow hedging strategies that convert variable-rate loans to fixed rates and fair value hedging strategies that convert fixed-rate medium- and long-term debt to variable rates. Interest and fees on loans included $(2) million and $24 million of cash flow hedge (loss) income for the three-month periods ended September 30, 2022 and 2021, respectively, and $45 million and $72 million for the nine-month periods ended September 30, 2022 and 2021, respectively. The following table details the effects of fair value hedging on the Consolidated Statements of Comprehensive Income. Interest on Medium- and Long-Term Debt Three Months Ended September 30, Nine Months Ended September 30, (in millions) 2022 2021 2022 2021 Total interest on medium- and long-term debt (a) $ 26 $ 9 $ 47 $ 27 Fair value hedging relationships: Interest rate contracts: Hedged items 28 25 79 76 Derivatives designated as hedging instruments (2) (17) (32) (51) (a) Includes the effects of hedging. For information on accumulated net (losses) gains on cash flow hedges, refer to Note 8. The following tables summarize the expected weighted average remaining maturity of the notional amount of risk management interest rate swaps, the weighted average interest rates associated with amounts expected to be received or paid on interest rate swap agreements, and for fair value swaps, the carrying amount of the related hedged items, as of September 30, 2022 and December 31, 2021. Cash flow swaps - receive fixed/pay floating rate on variable-rate loans September 30, 2022 December 31, 2021 Weighted average: Time to maturity (in years) 4.7 2.4 Receive rate (a) 2.20 % 1.84 % Pay rate (a), (b) 2.48 0.10 (a) Excludes forward starting swaps not effective as of the period shown. September 30, 2022 excluded $10.8 billion of forward starting swaps. December 31, 2021 excluded $3.0 billion of forward starting swaps. (b) Variable rates paid on receive fixed swaps designated as cash flow hedges are based on one-month LIBOR, BSBY or Secured Overnight Financing Rate (SOFR) rates in effect at September 30, 2022 and December 31, 2021. Derivative contracts with maturity dates beyond the LIBOR cessation date will fall back to the daily SOFR with a spread adjustment. Fair value swaps - receive fixed/pay floating rate on medium- and long-term debt (dollar amounts in millions) September 30, 2022 December 31, 2021 Carrying value of hedged items (a) $ 3,016 $ 2,796 Weighted average: Time to maturity (in years) 4.2 3.6 Receive rate 3.52 % 3.68 % Pay rate (b) 3.87 1.08 (a) Included $(132) million and $145 million of cumulative hedging adjustments at September 30, 2022 and December 31, 2021, respectively, which included $4 million and $5 million, respectively, of hedging adjustment on a discontinued hedging relationship. (b) Floating rates paid on receive fixed swaps designated as fair value hedges are based on one-month LIBOR rates in effect at September 30, 2022 and December 31, 2021. Derivative contracts with maturity dates beyond the LIBOR cessation date will fall back to the daily SOFR with a spread adjustment. Customer-Initiated and Other The Corporation enters into derivative transactions at the request of customers and generally takes offsetting positions with dealer counterparties to mitigate the inherent market risk. Income primarily results from the spread between the customer derivative and the offsetting dealer position. For customer-initiated foreign exchange contracts where offsetting positions have not been taken, the Corporation manages the remaining inherent market risk through individual foreign currency position limits and aggregate value-at-risk limits. These limits are established annually and reviewed quarterly. For those customer-initiated derivative contracts which were not offset or where the Corporation holds a position within the limits described above, the Corporation recognized $1 million in net gains in other noninterest income on the Consolidated Statements of Comprehensive Income for the three months ended September 30, 2022 and recognized no net gains and losses for the three months ended September 30, 2021 and nine months ended September 30, 2022 and 2021, respectively. Fair values of customer-initiated and other derivative instruments represent the net unrealized gains or losses on such contracts and are recorded on the Consolidated Balance Sheets. Changes in fair value are recognized on the Consolidated Statements of Comprehensive Income. The net gains recognized in income on customer-initiated derivative instruments, net of the impact of offsetting positions included in derivative income, were as follows: Three Months Ended September 30, Nine Months Ended September 30, (in millions) 2022 2021 2022 2021 Interest rate contracts $ 9 $ 2 $ 28 $ 26 Energy contracts 14 7 22 13 Foreign exchange contracts 12 11 36 33 Total $ 35 $ 20 $ 86 $ 72 Credit-Related Financial Instruments The Corporation issues off-balance sheet financial instruments in connection with commercial and consumer lending activities. The Corporation’s credit risk associated with these instruments is represented by the contractual amounts indicated in the following table. (in millions) September 30, 2022 December 31, 2021 Unused commitments to extend credit: Commercial and other $ 29,530 $ 25,910 Bankcard, revolving credit and home equity loan commitments 3,936 3,554 Total unused commitments to extend credit $ 33,466 $ 29,464 Standby letters of credit $ 3,390 $ 3,378 Commercial letters of credit 34 44 The Corporation maintains an allowance to cover current expected credit losses inherent in lending-related commitments, including unused commitments to extend credit, letters of credit and financial guarantees. The allowance for credit losses on lending-related commitments, included in accrued expenses and other liabilities on the Consolidated Balance Sheets, was $48 million and $30 million at September 30, 2022 and December 31, 2021, respectively. Unused Commitments to Extend Credit Commitments to extend credit are legally binding agreements to lend to a customer, provided there is no violation of any condition established in the contract. These commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many commitments expire without being drawn upon, the total contractual amount of commitments does not necessarily represent future cash requirements of the Corporation. Commercial and other unused commitments are primarily variable rate commitments. The allowance for credit losses on lending-related commitments included $44 million at September 30, 2022 and $27 million at December 31, 2021 for expected credit losses inherent in the Corporation’s unused commitments to extend credit. Standby and Commercial Letters of Credit Standby letters of credit represent conditional obligations of the Corporation which guarantee the performance of a customer to a third party. Standby letters of credit are primarily issued to support public and private borrowing arrangements, including commercial paper, bond financing and similar transactions. Commercial letters of credit are issued to finance foreign or domestic trade transactions. These contracts expire in decreasing amounts through the year 2028. The Corporation may enter into participation arrangements with third parties that effectively reduce the maximum amount of future payments which may be required under standby and commercial letters of credit. These risk participations covered $110 million and $98 million at September 30, 2022 and December 31, 2021, respectively, of the $3.4 billion of standby and commercial letters of credit outstanding at both September 30, 2022 and December 31, 2021. The carrying value of the Corporation’s standby and commercial letters of credit, included in accrued expenses and other liabilities on the Consolidated Balance Sheets, totaled $32 million at September 30, 2022, including $28 million in deferred fees and $4 million in the allowance for credit losses on lending-related commitments. At December 31, 2021, the comparable amounts were $32 million, $29 million and $3 million, respectively. The following table presents a summary of criticized standby and commercial letters of credit at September 30, 2022 and December 31, 2021. The Corporation's criticized list is generally consistent with the Special Mention, Substandard and Doubtful categories defined by regulatory authorities. The Corporation manages credit risk through underwriting, periodically reviewing and approving its credit exposures using Board committee approved credit policies and guidelines. (dollar amounts in millions) September 30, 2022 December 31, 2021 Total criticized standby and commercial letters of credit $ 35 $ 37 As a percentage of total outstanding standby and commercial letters of credit 1.0 % 1.1 % Other Credit-Related Financial Instruments The Corporation enters into credit risk participation agreements, under which the Corporation assumes credit exposure associated with a borrower’s performance related to certain interest rate derivative contracts. The Corporation is not a party to the interest rate derivative contracts and only enters into these credit risk participation agreements in instances in which the Corporation is also a party to the related loan participation agreements for such borrowers. The Corporation manages its credit risk on the credit risk participation agreements by monitoring the creditworthiness of the borrowers, which is based on the normal credit review process as if the Corporation had entered into the derivative instruments directly with the borrower. The notional amount of such credit risk participation agreements reflects the pro-rata share of the derivative instrument, consistent with its share of the related participated loan. The total notional amount of the credit risk participation agreements was approximately $894 million and $1.1 billion at September 30, 2022 and December 31, 2021, respectively, and the fair value was insignificant at September 30, 2022 and $1 million at December 31, 2021. The maximum estimated exposure to these agreements, as measured by projecting a maximum value of the guaranteed derivative instruments, assuming 100 percent default by all obligors on the maximum values, was insignificant at September 30, 2022 and $30 million at December 31, 2021. In the event of default, the lead bank has the ability to liquidate the assets of the borrower, in which case the lead bank would be required to return a percentage of the recouped assets to the participating banks. As of September 30, 2022, the weighted average remaining maturity of outstanding credit risk participation agreements was 3.9 years. In 2008, the Corporation sold its remaining ownership of Visa Class B shares and entered into a derivative contract. Under the terms of the derivative contract, the Corporation will compensate the counterparty primarily for dilutive adjustments made to the conversion factor of the Visa Class B shares to Class A shares based on the ultimate outcome of litigation involving Visa. Conversely, the Corporation will be compensated by the counterparty for any increase in the conversion factor from anti-dilutive adjustments. The notional amount of the derivative contract was equivalent to approximately 780,000 Visa Class B Shares. The fair value of the derivative liability, included in accrued expenses and other liabilities on the Consolidated Balance Sheets, was $12 million and $13 million at September 30, 2022 and December 31, 2021, respectively.

Variable Interest Entities (VIE

Variable Interest Entities (VIEs)	9 Months Ended
	Sep. 30, 2022
Variable Interest Entity, Not Primary Beneficiary, Disclosures [Abstract]
Variable Interest Entities (VIEs)	VARIABLE INTEREST ENTITIES (VIEs) The Corporation evaluates its interest in certain entities to determine if these entities meet the definition of a VIE and whether the Corporation is the primary beneficiary and should consolidate the entity based on the variable interests it held both at inception and when there is a change in circumstances that requires a reconsideration. The Corporation holds ownership interests in funds in the form of limited partnerships or limited liability companies (LLCs) investing in affordable housing projects that qualify for the low-income housing tax credit (LIHTC). The Corporation also directly invests in limited partnerships and LLCs which invest in community development projects, which generate similar tax credits to investors (other tax credit entities). As an investor, the Corporation obtains income tax credits and deductions from the operating losses of these tax credit entities. These tax credit entities meet the definition of a VIE; however, the Corporation is not the primary beneficiary of the entities, as the general partner or the managing member has both the power to direct the activities that most significantly impact the economic performance of the entities and the obligation to absorb losses or the right to receive benefits that could be significant to the entities. The Corporation accounts for its interests in LIHTC entities using the proportional amortization method. Ownership interests in other tax credit entities are accounted for under either the cost or equity method. Exposure to loss as a result of the Corporation's involvement in LIHTC entities and other tax credit entities at September 30, 2022 was limited to $451 million and $18 million, respectively. Investment balances, including all legally binding commitments to fund future investments, are included in accrued income and other assets on the Consolidated Balance Sheets. A liability is recognized in accrued expenses and other liabilities on the Consolidated Balance Sheets for all legally binding unfunded commitments to fund tax credit entities ($176 million at September 30, 2022). Amortization and other write-downs of LIHTC investments are presented on a net basis as a component of the provision for income taxes on the Consolidated Statements of Comprehensive Income, while amortization and write-downs of other tax credit investments are recorded in other noninterest income. The income tax credits and deductions are recorded as a reduction of income tax expense and a reduction of federal income taxes payable. The Corporation provided no financial or other support that was not contractually required to any of the above VIEs during the nine months ended September 30, 2022 and 2021. The following table summarizes the impact of these tax credit entities on the Corporation’s Consolidated Statements of Comprehensive Income. Three Months Ended September 30, Nine Months Ended September 30, (in millions) 2022 2021 2022 2021 Provision for income taxes: Amortization of LIHTC investments $ 19 $ 18 $ 54 $ 53 Low income housing tax credits (18) (17) (51) (50) Other tax benefits related to tax credit entities (5) (5) (14) (13) Total provision for income taxes $ (4) $ (4) $ (11) $ (10) For further information on the Corporation’s consolidation policy, see Note 1 to the consolidated financial statements in the Corporation's 2021 Annual Report.

Accordingly, carrying value has been adjusted to reflect the change in the fair value of the debt as a result of changes in the benchmark rate. Subordinated notes with remaining maturities greater than one year qualify as Tier 2 capital. Comerica Bank (the Bank), a wholly-owned subsidiary of the Corporation, is a member of the FHLB, which provides short-and long-term funding to its members through advances collateralized by real estate-related assets. Borrowing capacity is contingent on the amount of collateral available to be pledged to the FHLB. At September 30, 2022, $17.9 billion of real estate-related loans and $1.1 billion of investment securities were pledged to the FHLB as collateral for $500 million in short-term advances and providing an additional $9.6 billion of potential future borrowings. In third quarter 2022, the Bank issued $500 million of fixed-to-floating rate subordinated notes due in 2033, with a rate of 5.332% for the first ten years. The rate on the subordinated notes will reset on August 25, 2032 to Secured Overnight Financing Rate (SOFR) plus 261 basis points until called or matured. Additionally, the Bank entered into a fair value fixed-to- floating rate swap in which the Bank received a fixed rate of 2.67% and will pay a floating rate based on the SOFR for the first 10 years. Unamortized debt issuance costs deducted from the carrying amount of medium- and long-term debt totaled $9 million and $7 million at September 30, 2022 and December 31, 2021, respectively.

Income Tax Disclosure [Abstract]
Income Taxes and Tax-Related Items	INCOME TAXES AND TAX-RELATED ITEMS Net unrecognized tax benefits were $17 million and $18 million at September 30, 2022 and December 31, 2021, respectively. The Corporation anticipates that it is reasonably possible that final settlement of state tax issues will result in a favorable change to net unrecognized tax benefits of $5 million and penalties and interest of $4 million within the next twelve months. Included in accrued expenses and other liabilities on the Consolidated Balance Sheets was a liability for tax-related interest and penalties of $5 million and $6 million at September 30, 2022 and December 31, 2021, respectively. Net deferred tax assets were $1.1 billion at September 30, 2022, compared to $9 million at December 31, 2021. The increase of $1.1 billion in net deferred tax assets resulted primarily from increases to deferred tax assets related to net unrealized losses on investment securities available-for-sale and hedging gains and losses. Included in deferred tax assets at both September 30, 2022 and December 31, 2021 were $3 million of state net operating loss (NOL) carryforwards and $3 million of federal foreign tax carryforwards. State net operating loss carryforwards expire between 2022 and 2031 and federal foreign tax credit carryforwards expire between 2028 and 2030. The Corporation believes that it is more likely than not that the benefit from federal foreign tax credits and certain state NOL carryforwards will not be realized and, accordingly, maintains a federal valuation allowance of $3 million at both September 30, 2022 and December 31, 2021 and a state valuation allowance of $3 million and $2 million at September 30, 2022 and December 31, 2021, respectively. The determination regarding valuation allowance was based on evidence of loss carryback capacity, projected future reversals of existing taxable temporary differences to absorb the deferred tax assets and assumptions made regarding future events. In the ordinary course of business, the Corporation enters into certain transactions that have tax consequences. From time to time, the Internal Revenue Service (IRS) or other tax jurisdictions may review and/or challenge specific interpretive tax positions taken by the Corporation with respect to those transactions. The Corporation believes its tax returns were filed based upon applicable statutes, regulations and case law in effect at the time of the transactions. The IRS or other tax jurisdictions, an administrative authority or a court, if presented with the transactions, could disagree with the Corporation’s interpretation of the tax law. Based on current knowledge and probability assessment of various potential outcomes, the Corporation believes that current tax reserves are adequate, and the amount of any potential incremental liability arising is not expected to have a material adverse effect on the Corporation’s consolidated financial condition or results of operations. Probabilities and outcomes are reviewed as events unfold, and adjustments to the reserves are made when necessary.

Commitments and Contingencies Disclosure [Abstract]
Contingent Liabilities	CONTINGENT LIABILITIES Legal Proceedings and Regulatory Matters The Corporation and certain of its subsidiaries are subject to various other pending or threatened legal proceedings arising out of the normal course of business or operations. The Corporation believes it has meritorious defenses to the claims asserted against it in its other currently outstanding legal proceedings and, with respect to such legal proceedings, intends to continue to defend itself vigorously, litigating or settling cases according to management’s judgment as to what is in the best interests of the Corporation and its shareholders. Settlement may result from the Corporation's determination that it may be more prudent financially to settle, rather than litigate, and should not be regarded as an admission of liability. Further, from time to time, the Corporation is also subject to examinations, inquiries and investigations by regulatory authorities in areas including, but not limited to, compliance, risk management and consumer protection, which could lead to administrative or legal proceedings or settlements. For example, the Consumer Financial Protection Bureau (“CFPB”) is investigating certain of the Corporation's practices, and the Corporation has responded and continues to respond to the CFPB. We are unable to predict the outcome of these discussions at this time. Remedies in these proceedings or settlements may include fines, penalties, restitution or alterations in the Corporation's business practices and may result in increased operating expenses or decreased revenues. On at least a quarterly basis, the Corporation assesses its potential liabilities and contingencies in connection with outstanding legal proceedings and regulatory matters utilizing the latest information available. On a case-by-case basis, accruals are established for those legal claims and regulatory matters for which it is probable that a loss will be incurred and the amount of such loss can be reasonably estimated. The actual costs of resolving these claims and regulatory matters may be substantially higher or lower than the amounts accrued. Based on current knowledge, and after consultation with legal counsel, management believes current accruals are adequate, and the amount of any incremental liability arising from these matters is not expected to have a material adverse effect on the Corporation’s consolidated financial condition, results of operations or cash flows. For matters where a loss is not probable, the Corporation has not established an accrual. The Corporation believes the estimate of the aggregate range of reasonably possible losses, in excess of established accruals, for all legal proceedings and regulatory matters in which it is involved is from zero to approximately $80 million at September 30, 2022. This estimated aggregate range of reasonably possible losses is based upon currently available information for those legal proceedings and regulatory matters in which the Corporation is involved, taking into account the Corporation’s best estimate of such losses for those legal cases and regulatory matters for which such estimate can be made. For certain legal cases and regulatory matters, the Corporation does not believe that an estimate can currently be made. The Corporation’s estimate involves significant judgment, given the varying stages of the legal proceedings and regulatory matters (including the fact many are currently in preliminary stages), the existence in certain legal proceedings of multiple defendants (including the Corporation) whose share of liability has yet to be determined, the numerous yet-unresolved issues in many of the legal proceedings and regulatory matters (including issues regarding class certification and the scope of many of the claims) and the attendant uncertainty of the various potential outcomes of such legal proceedings and regulatory matters. Accordingly, the Corporation’s estimate will change from time to time, and actual losses may be more or less than the current estimate. In the event of unexpected future developments, it is possible the ultimate resolution of these matters, if unfavorable, may be material to the Corporation's consolidated financial condition, results of operations or cash flows. For information regarding income tax contingencies, refer to Note 11.

Segment Reporting [Abstract]
Business Segment Information	STRATEGIC LINES OF BUSINESS The Corporation has strategically aligned its operations into three major business segments: the Commercial Bank, the Retail Bank and Wealth Management. These business segments are differentiated based on the type of customer and the related products and services provided. In addition to the three major business segments, the Finance Division is also reported as a segment. Business segment results are produced by the Corporation’s internal management accounting system. This system measures financial results based on the internal business unit structure of the Corporation. The performance of the business segments is not comparable with the Corporation's consolidated results and is not necessarily comparable with similar information for any other financial institution. Additionally, because of the interrelationships of the various segments, the information presented is not indicative of how the segments would perform if they operated as independent entities. The management accounting system assigns balance sheet and income statement items to each business segment using certain methodologies, which are regularly reviewed and refined. From time to time, the Corporation may make reclassifications among the segments to more appropriately reflect management's current view of the segments, and methodologies may be modified as the management accounting system is enhanced and changes occur in the organizational structure and/or product lines. For comparability purposes, amounts in all periods are based on business unit structure and methodologies in effect at September 30, 2022. The following discussion provides information about the activities of each business segment. A discussion of the financial results and the factors impacting performance can be found in "Business Segments" in the "Strategic Lines of Business" section of the financial review. The Commercial Bank meets the needs of small and middle market businesses, multinational corporations and governmental entities by offering various products and services including commercial loans and lines of credit, deposits, cash management, capital market products, international trade finance, letters of credit, foreign exchange management services and loan syndication services. The Retail Bank includes a full range of personal financial services, consisting of consumer lending, consumer deposit gathering and mortgage loan origination. This business segment offers a variety of consumer products including deposit accounts, installment loans, credit cards, student loans, home equity lines of credit and residential mortgage loans. In addition, this business segment offers a subset of commercial products and services to micro-businesses whose primary contact is through the branch network. Wealth Management offers products and services consisting of fiduciary services, private banking, retirement services, investment management and advisory services, investment banking and brokerage services. This business segment also offers the sale of annuity products, as well as life, disability and long-term care insurance products. The Finance segment includes the Corporation’s securities portfolio and asset and liability management activities. This segment is responsible for managing the Corporation’s funding, liquidity and capital needs, performing interest sensitivity analysis and executing various strategies to manage the Corporation’s exposure to liquidity, interest rate risk and foreign exchange risk. The Other category includes the income and expense impact of equity and cash, tax benefits not assigned to specific business segments, charges of an unusual or infrequent nature that are not reflective of the normal operations of the business segments and miscellaneous other expenses of a corporate nature. For further information on the methodologies which form the basis for these results refer to Note 22 to the consolidated financial statements in the Corporation's 2021 Annual Report. Business segment financial results are as follows: Commercial Retail Wealth Management Finance Other Total (dollar amounts in millions) Three Months Ended September 30, 2022 Earnings summary: Net interest income (expense) $ 478 $ 188 $ 55 $ (22) $ 8 $ 707 Provision for credit losses 16 2 5 — 5 28 Noninterest income 169 29 77 6 (3) 278 Noninterest expenses 242 170 87 — 3 502 Provision (benefit) for income taxes 94 11 10 (6) (5) 104 Net income (loss) $ 295 $ 34 $ 30 $ (10) $ 2 $ 351 Net credit-related charge-offs $ 6 $ — $ — $ — $ 7 $ 13 Selected average balances: Assets $ 48,323 $ 2,799 $ 5,097 $ 22,133 $ 7,070 $ 85,422 Loans 44,043 2,066 4,973 — 31 51,113 Deposits 41,471 26,665 5,293 383 164 73,976 Statistical data: Return on average assets (a) 2.42 % 0.51 % 2.08 % n/m n/m 1.63 % Efficiency ratio (b) 37.54 76.81 65.92 n/m n/m 50.75 Three Months Ended September 30, 2021 Earnings summary: Net interest income (expense) $ 406 $ 149 $ 40 $ (124) $ 4 $ 475 Provision for credit losses (25) (5) (13) — 1 (42) Noninterest income 169 32 69 10 — 280 Noninterest expenses 223 159 79 — 4 465 Provision (benefit) for income taxes 83 4 10 (27) — 70 Net income (loss) $ 294 $ 23 $ 33 $ (87) $ (1) $ 262 Net credit-related charge-offs (recoveries) $ 4 $ (1) $ (1) $ — $ — $ 2 Selected average balances: Assets $ 43,366 $ 3,105 $ 4,956 $ 17,922 $ 22,004 $ 91,353 Loans 41,037 2,297 4,829 — (28) 48,135 Deposits 46,641 26,088 5,209 977 200 79,115 Statistical data: Return on average assets (a) 2.33 % 0.34 % 2.36 % n/m n/m 1.14 % Efficiency ratio (b) 38.40 87.18 72.83 n/m n/m 61.13 (a) Return on average assets is calculated based on the greater of average assets or average liabilities and attributed equity.

Accounting Policies [Abstract]
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In March 2022, the FASB issued ASU No. 2022-02, “Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructuring and Vintage Disclosures” (ASU 2022-02), which eliminates the accounting for troubled debt restructuring (TDR) while expanding modification and vintage disclosure requirements. Under the current guidance, a TDR occurs when a loan to a borrower experiencing financial difficulty is restructured with a concession provided that a creditor would not otherwise consider. ASU 2022-02 removes the TDR accounting model, instead requiring modifications to apply existing refinancing and restructuring guidance. The update also requires additional disclosures on the nature, magnitude and subsequent performance of certain types of modifications with borrowers experiencing financial difficulties. ASU 2022-02 further included a requirement to disclose gross charge-offs incurred by year of origination of the related loan or lease. ASU 2022-02 is effective for the Corporation on January 1, 2023, and must be applied prospectively, except that the recognition and measurement of TDRs may be applied using a modified retrospective approach. Early adoption is permitted. The Corporation is evaluating the impact of the new guidance to its disclosures but does not expect there to be a material impact on its financial condition or results of operation.

(b) Includes Small Business Administration Paycheck Protection Program (PPP) loans of $46 million and $458 million at September 30, 2022 and December 31, 2021, respectively. (c) Includes loans with an internal rating of special mention, substandard loans for which the accrual of interest has not been discontinued and nonaccrual loans. Special mention loans have potential credit weaknesses that deserve management’s close attention, such as loans to borrowers who may be experiencing financial difficulties that may result in deterioration of repayment prospects from the borrower at some future date. Accruing substandard loans have a well-defined weakness, or weaknesses, such as loans to borrowers who may be experiencing losses from operations or inadequate liquidity of a degree and duration that jeopardizes the orderly repayment of the loan. Substandard loans are also distinguished by the distinct possibility of loss in the future if these weaknesses are not corrected. Nonaccrual loans are loans for which the accrual of interest has been discontinued. For further information regarding nonaccrual loans, refer to the Nonperforming Assets subheading in Note 1 - Basis of Presentation and Accounting Policies on page F-52 in the Corporation's 2021 Annual Report. These categories are generally consistent with the "special mention" and "substandard" categories as defined by regulatory authorities. A minority of nonaccrual loans are consistent with the "doubtful" category.

[1]Includes all loans not included in the categories of special mention, substandard or nonaccrual.[2]Includes Small Business Administration Paycheck Protection Program (PPP) loans of $46 million and $458 million at September 30, 2022 and December 31, 2021, respectively.[3]Includes loans with an internal rating of special mention, substandard loans for which the accrual of interest has not been discontinued and nonaccrual loans. Special mention loans have potential credit weaknesses that deserve management’s close attention, such as loans to borrowers who may be experiencing financial difficulties that may result in deterioration of repayment prospects from the borrower at some future date. Accruing substandard loans have a well-defined weakness, or weaknesses, such as loans to borrowers who may be experiencing losses from operations or inadequate liquidity of a degree and duration that jeopardizes the orderly repayment of the loan. Substandard loans are also distinguished by the distinct possibility of loss in the future if these weaknesses are not corrected. Nonaccrual loans are loans for which the accrual of interest has been discontinued. For further information regarding nonaccrual loans, refer to the Nonperforming Assets subheading in Note 1 - Basis of Presentation and Accounting Policies on page F-52 in the Corporation's 2021 Annual Report. These categories are generally consistent with the "special mention" and "substandard" categories as defined by regulatory authorities. A minority of nonaccrual loans are consistent with the "doubtful" category.
