Accounting Policies [Abstract]
Basis of Presentation and Accounting Policies	Note 1 - Basis of Presentation and Accounting Policies General The accompanying unaudited interim consolidated financial statements of Synovus Financial Corp. include the accounts of the Parent Company and its consolidated subsidiaries. Synovus Financial Corp. is a financial services company based in Columbus, Georgia. Through its wholly-owned subsidiary, Synovus Bank, a Georgia state-chartered bank that is a member of the Federal Reserve System, the Company provides commercial and consumer banking in addition to a full suite of specialized products and services, including private banking, treasury management, wealth management, mortgage services, premium finance, asset-based lending, structured lending, capital markets, and international banking. Synovus also provides financial planning and investment advisory services through its wholly-owned subsidiaries, Synovus Trust and Synovus Securities, as well as its GLOBALT and Creative Financial Group divisions. Synovus Bank is positioned in markets in the Southeast, with 246 branches and 358 ATMs in Alabama, Florida, Georgia, South Carolina, and Tennessee. The accompanying unaudited interim consolidated financial statements have been prepared in accordance with the instructions to the SEC Form 10-Q and Article 10 of Regulation S-X; therefore, they do not include all information and footnotes necessary for a fair presentation of financial position, results of operations, comprehensive income (loss), and cash flows in conformity with GAAP. All adjustments consisting of normally recurring accruals that, in the opinion of management, are necessary for a fair presentation of the consolidated financial position and results of operations for the periods covered by this Report have been included. The accompanying unaudited interim consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes appearing in Synovus' 2022 Form 10-K. Acquisition On June 1, 2023, Synovus acquired a 60% equity interest in Qualpay, Inc., a provider of a cloud-based platform that combines a payment gateway with merchant processing solutions, allowing merchants and independent software vendors to integrate payments into their software or websites. In addition, Synovus acquired three of the five seats on Qualpay's Board of Directors. Under the terms of the agreement, Synovus acquired a controlling interest in Qualpay in exchange for the settlement of Qualpay's debt to Synovus of $31.1 million and $7.0 million in cash. Synovus accounted for the transaction as a business combination and recorded the assets acquired, which primarily consisted of intangible assets and goodwill, liabilities assumed, noncontrolling interest, and consideration exchanged at their preliminary estimated fair values on the acquisition date. Refer to Note 4 - Goodwill and Other Intangible Assets for additional information. The balance of the noncontrolling interest at June 30, 2023 was $25.2 million. The transaction was not material to the consolidated statements of income for the three and six months ended June 30, 2023. Investments in Tax Credit Structures Synovus invests in certain LIHTC partnerships, which are engaged in the development and operation of affordable multi-family housing pursuant to Section 42 of the Code. Additionally, Synovus invests in certain new market tax credit partnerships pursuant to Section 45D of the Code, certain HTCs pursuant to Section 47 of the Code, and certain solar energy tax credit partnerships pursuant to Section 48 of the Code. Synovus typically acts as a limited partner in these investments and does not exert control over the operating or financial policies of the partnerships and as such, is not considered the primary beneficiary of the partnership. For certain of its LIHTC investments, Synovus provides financing during the construction and development of the properties and is at risk for the funded amount of its equity investment plus the outstanding amount of any construction loans in excess of the fair value of the collateral for the loan, but has no obligation to fund the operations or working capital of the partnerships and is not exposed to losses beyond Synovus’ investment. Synovus receives tax credits related to these investments, which are subject to recapture by taxing authorities based on compliance provisions required to be met at the project level. Synovus applies the proportional amortization method of accounting for its LIHTC and HTC partnerships. Effective January 1, 2023, upon the adoption of ASU 2023-02, Synovus also began applying the proportional amortization method of accounting to its qualifying new market tax credit partnership. The proportional amortization method recognizes the amortized cost of the investment as a component of income tax expense. Prior to the adoption of ASU 2023-02, Synovus applied the equity method of accounting to its new market tax credit partnership. For the three and six months ended June 30, 2023, Synovus recognized LIHTC, HTC, and new market tax credit partnership tax credits of $10.9 million and $21.8 million, respectively, and amortization expense of $10.7 million and $20.8 million, respectively, which were included within income tax expense in the consolidated statements of income. For the three and six months ended June 30, 2022, Synovus recognized LIHTC investment partnerships tax credits of $7.8 million and $15.3 million, respectively, and amortization expense of $8.0 million and $16.0 million, respectively, which were included within income tax expense in the consolidated statements of income. Reclassifications Prior periods' consolidated financial statements are reclassified whenever necessary to conform to the current periods' presentation. Use of Estimates in the Preparation of Financial Statements In preparing the consolidated financial statements in accordance with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the respective consolidated balance sheets and the reported amounts of revenue and expense for the periods presented. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the ACL, estimates of fair value, income taxes, and contingent liabilities. Recent Accounting Pronouncements The following table provides a brief description of accounting standards adopted or issued in 2023 and the estimated effect on the Company’s financial statements. Standard Description Required date of adoption Effect on Company's financial statements or other significant matters Standards Adopted ASU 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosure In March 2022, the FASB issued ASU 2022-02 to eliminate TDR accounting guidance while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. The ASU also provides guidance for vintage table disclosures and gross write-offs. The ASU requires an entity to disclose current-period gross write-offs by year of origination for financing receivables within the scope of Subtopic 326-20. January 1, 2023 The Company adopted this standard on January 1, 2023 on a prospective basis. The adoption of this standard did not have a material impact to the consolidated financial statements. See Note 3, Loans and Allowance for Loan Losses, for the required disclosures in accordance with this ASU. ASU 2023-02, Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method In March 2023, the FASB issued ASU 2023-02, which expands the population of investments for which an investor may elect to apply the proportional amortization method. Under the ASU, an investor in a tax equity investment may elect the proportional amortization method for qualifying investments on a tax credit program-by-program basis. To qualify for the proportional amortization method, an investment must meet the criteria previously applicable to LIHTC investments, as clarified by the ASU. January 1, 2024. Early adoption is permitted as of an interim period with retrospective application back to the beginning of the fiscal year. The Company early adopted this standard on January 1, 2023, on a modified retrospective basis. The adoption of this standard did not have a material impact to the consolidated financial statements. The Company recognized a cumulative effect adjustment of $297 thousand at adoption to decrease the beginning balance of retained earnings as of January 1, 2023, for the difference between the previous method used to account for the tax equity investment and the application of the proportional amortization method since the investment was entered into.

Synovus does not intend to sell investment securities in an unrealized loss position prior to the recovery of the unrealized loss, which may not be until maturity, and has the ability and intent to hold those securities for that period of time. Additionally, Synovus is not currently aware of any circumstances which will require it to sell any of the securities that are in an unrealized loss position prior to the respective securities' recovery of all such unrealized losses. As such, no write-downs to the amortized cost basis of the portfolio were recorded at June 30, 2023. At June 30, 2023, no ACL was established for investment securities. Substantially all of the unrealized losses on the securities portfolio were the result of changes in market interest rates compared to the date the securities were acquired rather than the credit quality of the issuers or underlying loans. U.S. Treasury and agency securities and agency mortgage-backed securities are issued, guaranteed or otherwise supported by the United States government, an agency of the United States government, or a government sponsored enterprise. The amortized cost and fair value by contractual maturity of investment securities available for sale at June 30, 2023 are shown below. The expected life of MBSs or CMOs may differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties. For purposes of the maturity table, MBSs and CMOs, which are not due at a single maturity date, have been classified based on the final contractual maturity date.

Of the interest income recognized during the three months ended June 30, 2023 and 2022, cash-basis interest income was $7.8 million and $410 thousand, respectively. Cash-basis interest income was $9.4 million and $964 thousand for the six months ended June 30, 2023 and 2022, respectively. Pledged Loans Loans with carrying values of $23.47 billion and $16.09 billion, respectively, were pledged as collateral for borrowings and capacity at June 30, 2023 and December 31, 2022, respectively, to the FHLB and Federal Reserve Bank. Portfolio Segment Risk Factors The risk characteristics and collateral information of each portfolio segment are as follows: Commercial and Industrial Loans - The C&I loan portfolio is comprised of general middle market and commercial banking clients across a diverse set of industries. In accordance with Synovus' lending policy, each loan undergoes a detailed underwriting process, which incorporates uniform underwriting standards and oversight in proportion to the size and complexity of the lending relationship. These loans are secured by collateral such as business equipment, inventory, and real estate. Credit decisions on loans in the C&I portfolio are based on cash flow from the operations of the business as the primary source of repayment of the debt, with underlying real estate or other collateral being the secondary source of repayment. Commercial Real Estate Loans - CRE loans primarily consist of income-producing investment properties loans. Additionally, CRE loans include 1-4 family properties loans as well as land and development loans. Investment properties loans consist of construction and mortgage loans for income-producing properties and are primarily made to finance multi-family properties, hotels, office buildings (medical and non-medical), shopping centers, warehouses and other commercial development properties. 1-4 family properties loans include construction loans to homebuilders and commercial mortgage loans related to 1-4 family rental properties and are almost always secured by the underlying property being financed by such loans. These properties are primarily located in the markets served by Synovus. Land and development loans include commercial and residential development as well as land acquisition loans and are secured by land held for future development, typically in excess of one year. Properties securing these loans are substantially within markets served by Synovus, and our preference is to obtain some level of recourse from project sponsors. Loans in this portfolio are underwritten based on the LTV of the collateral and the capacity of the guarantor(s). Consumer Loans - The consumer loan portfolio consists of a wide variety of loan products offered through Synovus' banking network, including first and second residential mortgages, home equity, and consumer credit card loans, as well as home improvement loans, student, personal, and auto loans from third-party lending ("other consumer loans"). Together, consumer mortgages and home equity comprise the majority of Synovus' consumer loans and are secured by first and second liens on residential real estate primarily located in the markets served by Synovus. The primary source of repayment for all consumer loans is generally the personal income of the borrower(s). Credit Quality Indicators The credit quality of the loan portfolio is reviewed and updated no less frequently than annually using the standard asset classification system utilized by the federal banking agencies. These classifications are divided into three groups: Not Criticized (Pass), Special Mention, and Classified or Adverse rating (Substandard, Doubtful, and Loss) and are defined as follows: Pass - loans which are well protected by the current net worth and paying capacity of the obligor (or guarantors, if any) or by the fair value, less cost to acquire and sell in a timely manner, of any underlying collateral. Special Mention - loans which have potential weaknesses that deserve management's close attention. These loans are not adversely classified and do not expose an institution to sufficient risk to warrant an adverse classification. Substandard - loans which are inadequately protected by the current net worth and paying capacity of the obligor or by the collateral pledged, if any. Loans with this classification are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Doubtful - loans which have all the weaknesses inherent in loans categorized as Substandard with the added characteristic that the weaknesses make collection or liquidation in full highly questionable and improbable on the basis of currently known facts, conditions, and values. Loss - loans which are considered by management to be uncollectible and of such little value that their continuance on the institution's books as an asset, without establishment of a specific valuation allowance or charge-off, is not warranted. Synovus fully reserves for any loans rated as Loss. In the following tables, consumer loans are generally assigned a risk grade similar to the classifications described above; however, upon reaching 90 days and 120 days past due, they are generally downgraded to Substandard and Loss, respectively, in accordance with the FFIEC Retail Credit Classification Policy. Additionally, in accordance with Interagency Supervisory Guidance, the risk grade classifications of consumer loans (consumer mortgages and home equity) secured by junior liens on 1-4 family residential properties also consider available information on the payment status of any associated senior liens with other financial institutions. The following table summarizes each loan portfolio class by risk grade and origination year as of June 30, 2023 as required under CECL. In addition, gross charge-offs by loan portfolio class and origination year as of June 30, 2023 are included below as a result of the adoption of ASU 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosure.

(3) Loans within Loss risk grade are on non-accrual status and have an ALL equal to the full loan amount. Collateral-Dependent Loans We classify a loan as collateral-dependent when our borrower is experiencing financial difficulty, and we expect repayment to be provided substantially through the operation or sale of collateral. Our commercial loans have collateral that is comprised of real estate and business assets. Our consumer loans have collateral that is substantially comprised of residential real estate. There were no significant changes in the extent to which collateral secures our collateral-dependent loans during the three and six months ended June 30, 2023. Rollforward of Allowance for Loan Losses The following tables detail the changes in the ALL by loan segment for the three and six months ended June 30, 2023 and 2022. During the three and six months ended June 30, 2023 and 2022, Synovus charged-off $1.3 million and $7.9 million in previously established reserves for credit losses associated with the transfer of $3.8 million and $427.9 million, respectively, in certain third-party consumer loans to held for sale as part of our overall balance sheet management strategy. $711 thousand in reserves were added as a result of purchases of $10.6 million of third-party lending loans for the three months ended June 30, 2023. $3.7 million and $7.5 million in reserves were added as a result of purchases of $180.2 million and $361.6 million of third-party lending loans for the three and six months ended June 30, 2022, respectively.

The ACL increased $26.1 million compared to the December 31, 2022 ACL of $500.9 million, which consisted of the ALL of $443.4 million and the reserve for unfunded commitments of $57.5 million. The ACL to loans coverage ratio of 1.19% at June 30, 2023 was 4 bps higher compared to December 31, 2022. The increase in the ACL from December 31, 2022 resulted primarily from deterioration in economic factors and increased specific reserves. The ACL is estimated using a two-year reasonable and supportable forecast period. To the extent the lives of the loans in the portfolio extend beyond the period for which a reasonable and supportable forecast can be made, the Company reverts on a straight-line basis back to the historical rates over a one-year period. Synovus utilizes multiple economic forecast scenarios sourced from a reputable third-party provider that are probability-weighted internally. The current scenarios include a consensus baseline forecast, an upside scenario reflecting an accelerated recovery, a downside scenario that reflects adverse economic conditions, and a stagflation scenario, which also assumes adverse economic conditions. At June 30, 2023, the unemployment rate is the input that most significantly impacts our estimate. The multi-scenario forecast used in our estimate includes a peak weighted average unemployment rate of 5.7% over the forecasted period at June 30, 2023, compared to 5.1% at December 31, 2022. Financial Difficulty Modifications When borrowers are experiencing financial difficulty, Synovus may make certain loan modifications as part of its loss mitigation strategies to maximize expected payment. All loan modifications, renewals, and refinancings where borrowers are experiencing financial difficulty are evaluated for FDM classification. To be classified as an FDM, the modifications must be in the form of providing an interest rate reduction relative to the current interest rate, principal forgiveness, or an other-than-insignificant payment delay or extension of the maturity of the loan. An FDM is tracked for 12 months following the modification(s) granted. The effect of these modifications is already included in the ACL because our use of a DCF model captures loan level changes including modified terms as part of the estimation process.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	Note 4 - Goodwill and Other Intangible Assets Effective April 1, 2023, Synovus changed its internal management reporting structure to transfer Capital Markets activities and related personnel from the Financial Management Services segment to the Wholesale Banking segment. See Note 10 - Segment Reporting for additional information. In connection with the transfer, management reallocated a portion of the Wealth Management goodwill that was attributable to the Financial Management Services segment to Wholesale Banking using a relative fair value approach, and no indicators of impairment were identified. On June 1, 2023, Synovus acquired a 60% equity interest and a majority of the Board seats in Qualpay, which constituted a business combination. In connection with the acquisition, Synovus recorded $23.2 million of goodwill and $38.7 million of other intangible assets based on preliminary fair value estimates of the assets acquired and liabilities assumed in the transaction. Upon receipt of final fair value estimates during the measurement period, which must be within one year of the acquisition date, Synovus will record any adjustments to the preliminary fair value estimates in the reporting period in which the adjustments are determined. See Note 1 - Basis of Presentation and Accounting Policies for additional information on the Qualpay transaction. Goodwill allocated to each reporting unit at June 30, 2023 and December 31, 2022 is presented as follows: (in thousands) Wholesale Banking Reporting Unit Community Banking Reporting Unit Consumer Banking Reporting Unit Wealth Management Reporting Unit Total Goodwill Balance at December 31, 2022 $ 171,636 $ 141,622 $ 114,701 $ 24,431 $ 452,390 Changes during the period from: Reallocation 4,197 — — (4,197) — Acquisition — 23,183 — — 23,183 Balance at June 30, 2023 $ 175,833 $ 164,805 $ 114,701 $ 20,234 $ 475,573 Goodwill is evaluated for impairment on an annual basis or whenever an event occurs or circumstances change to indicate that it is more likely than not that an impairment loss has been incurred (i.e., a triggering event). Synovus performs its annual evaluation of goodwill impairment during the fourth quarter of each year. During the second quarter of 2023, Synovus assessed the events and circumstances that have generated significant market trading volatility in the banking industry, particularly for regional banks like Synovus. Due to the uncertain environment as well as Synovus' stock price trading below book value during the month of May 2023, Synovus elected to perform a quantitative assessment of goodwill impairment as of May 31, 2023, which included determining the estimated fair value of each reporting unit containing goodwill, utilizing a combination of discounted cash flow and market-based approaches, and comparing that fair value to each reporting unit's carrying amount. The discounted cash flow method included updated internal forecasts, long-term profitability targets, growth rates, and discount rates. The market approach was based on a comparison of certain financial metrics of Synovus' reporting units to guideline public company peers. Based on the quantitative assessment performed, the fair value of each of these reporting units exceeded their respective carrying values; therefore, we concluded goodwill was not impaired as of our May 31, 2023 test date and determined that it was not more likely than not that the fair value had declined below carrying value at the reporting until level as of June 30, 2023. The following table shows the gross carrying amount and accumulated amortization of other intangible assets as of June 30, 2023 and December 31, 2022. The CDI is being amortized over its estimated useful life of approximately ten years utilizing an accelerated method. Other intangible assets resulting from the Qualpay acquisition, which primarily include client relationships, partner relationships, and developed technology, are being amortized on a straight-line basis over their estimated useful lives ranging from five (in thousands) Gross Carrying Amount Accumulated Amortization Net Carrying Value June 30, 2023 CDI $ 57,400 $ (38,615) $ 18,785 Client Relationships 29,300 (6,854) 22,446 Partner Relationships 6,900 (115) 6,785 Developed Technology 11,091 (185) 10,906 Other 3,900 (1,284) 2,616 Total other intangible assets $ 108,591 $ (47,053) $ 61,538 December 31, 2022 CDI 57,400 (35,484) $ 21,916 Client Relationships 10,800 (6,136) 4,664 Other 1,700 (1,156) 544 Total other intangible assets $ 69,900 $ (42,776) $ 27,124

Derivative Instruments and Hedg

Derivative Instruments and Hedging Activities	6 Months Ended

Summary of Derivative Instruments [Abstract]
Derivative Instruments and Hedging Activities	Note 7 - Derivative Instruments and Hedging Activities Synovus utilizes derivative instruments to manage its exposure to various types of interest rate risk, exposures related to liquidity and credit risk, and to facilitate client transactions. The primary types of derivative instruments utilized by Synovus consist of interest rate swaps, interest rate lock commitments made to prospective mortgage loan clients, commitments to sell fixed-rate mortgage loans, and foreign currency exchange forwards. Interest rate lock commitments represent derivative instruments since it is intended that such loans will be sold. Synovus also provides foreign currency exchange services, primarily forward contracts, with counterparties to allow commercial clients to mitigate exchange rate risk. Synovus covers its risk by entering into an offsetting foreign currency exchange forward contract. Synovus enters into risk participation agreements with financial institution counterparties where we are either a participant or a lead bank so that the risk of default on the interest rate swaps is shared. Synovus either pays or receives a fee depending on the participation type. Synovus is party to master netting arrangements with its dealer counterparties; however, Synovus does not offset assets and liabilities under these arrangements for financial statement presentation purposes. See "Part II - Item 8. Financial Statements and Supplementary Data - Note 1 - Summary of Significant Accounting Policies" to the consolidated financial statements of Synovus' 2022 Form 10-K for additional information regarding accounting policies for derivatives. Hedging Derivatives Cash flow hedging relationships mitigate exposure to the variability of future cash flows or other forecasted transactions. Synovus has entered into interest rate swap contracts to manage overall cash flow changes related to interest rate risk exposure on index-based variable rate commercial loans. The contracts effectively modify Synovus' exposure to interest rate risk by utilizing receive fixed/pay index-based variable rate interest rate swaps. For cash flow hedges, the effective portion of the gain or loss on the derivative instrument is reported initially as a component of accumulated other comprehensive income (loss), net of the tax impact, and subsequently reclassified into earnings when the hedged transaction affects earnings with the impacts recorded in the same income statement line item used to present the earnings effect of the hedged item. When a cash flow hedge relationship is discontinued but the hedged cash flows, or forecasted transactions, are still expected to occur, gains or losses that were accumulated in OCI are amortized into earnings over the same periods in which the hedged transactions are still expected to affect earnings. If, however, it is probable the forecasted transactions will no longer occur, the remaining accumulated amounts in OCI for the impacted cash flow hedges are immediately recognized in earnings. Synovus recorded no unrealized gains (losses) during the three and six months ended June 30, 2023 and 2022 related to terminated cash flow hedges. Synovus recognized a pre-tax loss of $6.1 million and $11.5 million during the three and six months ended June 30, 2023, respectively, and pre-tax income of $1.0 million and $3.2 million for the three and six months ended June 30, 2022, respectively, related to the amortization of terminated cash flow hedges. Amounts related to the amortization of terminated cash flow hedges are being recognized into earnings in conjunction with the effective terms of the original swaps through the third quarter of 2026. As of June 30, 2023, Synovus expects to reclassify into earnings approximately $161 million in pre-tax loss due to the receipt or payment of interest payments on all cash flow hedges within the next twelve months. Included in this amount is approximately $23 million in pre-tax loss related to the amortization of terminated cash flow hedges. As of June 30, 2023, the maximum length of time over which Synovus is hedging its exposure to the variability in future cash flows is through the fourth quarter of 2027. Fair value hedging relationships mitigate exposure to the change in fair value of an asset or liability. Synovus has entered into receive-fixed, pay-variable interest rate swap contracts to hedge the change in the fair value due to fluctuations in market interest rates for outstanding fixed-rate long-term debt and fixed-rate term interest-bearing deposits. The changes in fair value of the fair value hedges are recorded through earnings with an offset against changes in the fair value of the hedged item within interest expense in the consolidated statements of income. All components of each derivative instrument’s gain/(loss) are included in the assessment of hedge effectiveness. Derivatives Not Designated as Hedges Derivatives not designated as hedges include those that are entered into as either economic hedges to facilitate client needs or as part of Synovus' overall risk management strategy. Economic hedges are those that do not qualify to be treated as a fair value hedge or cash flow hedge for accounting purposes but are necessary to economically manage the risk exposure associated with the assets and liabilities of Synovus. For derivative instruments that are not designated as hedging instruments, changes in the fair value of the derivatives are recognized in earnings immediately. Counterparty Credit Risk and Collateral Entering into derivative contracts potentially exposes Synovus to the risk of counterparties’ failure to fulfill their legal obligations, including, but not limited to, potential amounts due or payable under each derivative contract. Notional principal amounts are often used to express the volume of these transactions, but the amounts potentially subject to credit risk are much smaller. Synovus assesses the credit risk of its dealer counterparties by regularly monitoring publicly available credit rating information, evaluating other market indicators, and periodically reviewing detailed financials. Dealer collateral requirements are determined via risk-based policies and procedures and in accordance with existing agreements. Synovus seeks to minimize dealer credit risk by dealing with highly rated counterparties and by obtaining collateral for exposures above certain predetermined limits. Management closely monitors credit conditions within the client swap portfolio, which management deems to be of higher risk than dealer counterparties. Collateral is secured at origination and credit related fair value adjustments are recorded against the asset value of the derivative as deemed necessary based upon an analysis, which includes consideration of the current asset value of the swap, client risk rating, collateral value, and client standing with regards to its swap contractual obligations and other related matters. Such asset values fluctuate based upon changes in interest rates regardless of changes in notional amounts and changes in client specific risk. Collateral Requirements Certain derivative transactions have collateral requirements, both at the inception of the trade and as the value of each derivative position changes. As of June 30, 2023 and December 31, 2022, Synovus had recorded the right to reclaim cash collateral of $87.5 million and $66.8 million, respectively. As of June 30, 2023 and December 31, 2022, Synovus had recorded the obligation to return cash collateral of $5.7 million and $7.7 million, respectively. For derivatives cleared through central clearing houses, the variation margin payments made are legally characterized as settlements of the derivatives. As a result, these variation margin payments are netted against the fair value of the respective derivative contracts in the consolidated balance sheets and related disclosures. The following table reflects the estimated fair value of derivative instruments included in other assets and other liabilities on the consolidated balance sheets along with their respective notional amounts on a gross basis.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 9 - Commitments and Contingencies In the normal course of business, Synovus enters into commitments to extend credit such as loan commitments and letters of credit to meet the financing needs of its clients. Synovus uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. Commitments to extend credit are agreements to lend to a client as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Synovus also has commitments to fund certain tax credits, CRA partnerships, and other investments. The contractual amount of these financial instruments represents Synovus' maximum credit risk should the counterparty draw upon the commitment, and should the counterparty subsequently fail to perform according to the terms of the contract. Since many of the commitments are expected to expire without being drawn upon, total commitment amounts do not necessarily represent future cash requirements. Additionally, certain commitments (primarily consumer) can generally be canceled by providing notice to the borrower. The ACL associated with unfunded commitments and letters of credit is recorded within other liabilities on the consolidated balance sheets. At June 30, 2023 and December 31, 2022, the ACL for unfunded commitments was $55.7 million and $57.5 million, respectively. Additionally, an immaterial amount of unearned fees relating to letters of credit are recorded within other liabilities on the consolidated balance sheets. Synovus also invests in tax credit partnerships, CRA partnerships, including SBIC programs, and other investments. The SBIC is a program initiated by the SBA in 1958 to assist in the funding of small business loans. (in thousands) June 30, 2023 December 31, 2022 Letters of credit (1) $ 203,911 $ 220,622 Commitments to fund commercial and industrial loans 10,143,330 9,970,733 Commitments to fund commercial real estate, construction, and land development loans 3,100,361 3,629,531 Commitments under home equity lines of credit 2,163,660 2,156,641 Unused credit card lines 463,440 461,443 Other loan commitments 698,093 742,976 Total letters of credit and unfunded lending commitments $ 16,772,795 $ 17,181,946 Tax credits, CRA partnerships, and other investments with a future funding commitment: Carrying amount included in other assets $ 525,072 $ 488,944 Amount of future funding commitments 300,722 283,212 Permanent and short-term construction loans and letter of credit commitments (2) 208,699 177,998 Funded portion of permanent and short-term loans and letters of credit (3) 195,748 234,166 (1) Represent the contractual amount net of risk participations purchased of approximately $23.4 million and $25.7 million at June 30, 2023 and December 31, 2022, respectively. (2) Represent the contractual amount net of risk participations of $10.0 million and $4.7 million at June 30, 2023 and December 31, 2022, respectively. (3) Represent the contractual amount net of risk participations of $2.9 million and $6.9 million at June 30, 2023 and December 31, 2022, respectively. Merchant Services In accordance with credit and debit card association rules, Synovus provides merchant processing services for clients with a contractual arrangement under which certain sales and processing support are provided through an outside merchant services provider with Synovus owning the merchant contract relationship. In addition, Synovus sponsors various third-party MPS businesses that process credit and debit card transactions on behalf of merchants. In connection with these services, a liability may arise in the event of a billing dispute between the merchant and a cardholder that is ultimately resolved in the cardholder's favor. If the merchant defaults on its obligations, the cardholder, through its issuing bank, generally has until six months after the date of the transaction to present a chargeback to the MPS, which is primarily liable for any losses on covered transactions. However, if a sponsored MPS fails to meet its obligations, then Synovus, as the sponsor, could be held liable for the disputed amount. Synovus seeks to mitigate this risk through its contractual arrangements with the MPS and the merchants by withholding future settlements, retaining cash reserve accounts and/or obtaining other security. For the three and six months ended June 30, 2023, Synovus and the sponsored entities processed and settled $29.39 billion and $59.50 billion of transactions, respectively. For the three and six months ended June 30, 2022, Synovus and the sponsored entities processed and settled $31.00 billion and $59.60 billion of transactions, respectively. Synovus previously covered chargebacks for Qualpay when their cash reserve account was unavailable to support them. The remaining amount, net of reserves, included in other assets and classified in NPAs, was $15.3 million as of December 31, 2022. During the first quarter of 2023, Synovus received regulatory approval for the previously announced proposed strategic investment in Qualpay. Upon regulatory approval, Synovus wrote up the balance to the contractual amount due of $31.1 million by reversing a prior impairment charge of $2.7 million through non-interest expense and recognizing a recovery of $13.1 million in non-interest revenue. On June 1, 2023, the Qualpay acquisition closed, and the contractual amount due was settled. See Note 1 - Basis of Presentation and Accounting Policies for additional discussion on the Qualpay acquisition. Legal Proceedings Synovus and its subsidiaries are subject to various legal proceedings, claims and disputes that arise in the ordinary course of its business. Additionally, in the ordinary course of business, Synovus and its subsidiaries are subject to regulatory and governmental examinations, information gathering requests, inquiries and investigations. Synovus, like many other financial institutions, has been the target of legal actions and other proceedings asserting claims for damages and related relief for losses. These actions include mortgage loan and other loan put-back claims, claims and counterclaims asserted by individual borrowers related to their loans, allegations of violations of state and federal laws and regulations relating to banking practices, including putative class action matters. In addition to actual damages, if Synovus does not prevail in such asserted legal actions, credit-related litigation could result in additional write-downs or charge-offs of assets, which could adversely affect Synovus' results of operations during the period in which the write-down or charge-off were to occur. Synovus carefully examines and considers each legal matter, and, in those situations where Synovus determines that a particular legal matter presents loss contingencies that are both probable and reasonably estimable, Synovus establishes an appropriate reserve. An event is considered to be probable if the future event is likely to occur. While the final outcome of any legal proceeding is inherently uncertain, based on the information currently available, advice of counsel and available insurance coverage, management believes that the amounts accrued with respect to legal matters as of June 30, 2023 are adequate. The actual costs of resolving legal claims may be higher or lower than the amounts accrued. In addition, where Synovus determines that there is a reasonable possibility of a loss in respect of legal matters, Synovus considers whether it is able to estimate the total reasonably possible loss or range of loss. Under GAAP, an event is “reasonably possible” if “the chance of the future event or events occurring is more than remote but less than likely,” and an event is “remote” if the “chance of the future event or events occurring is slight." In many situations, Synovus may be unable to estimate reasonably possible losses due to the preliminary nature of the legal matters, as well as a variety of other factors and uncertainties. For those legal matters where Synovus is able to estimate a range of reasonably possible losses, management currently estimates the aggregate range from our outstanding litigation is from zero to $5 million in excess of the amounts accrued, if any, related to those matters. This estimated aggregate range is based upon information currently available to Synovus, and the actual losses could prove to be lower or higher. As there are further developments in these legal matters, Synovus will reassess these matters, and the estimated range of reasonably possible losses may change as a result of this assessment. Based on Synovus' current knowledge and advice of counsel, management presently does not believe that the liabilities arising from these legal matters will have a material adverse effect on Synovus' consolidated financial condition, results of operations or cash flows. However, it is possible that the ultimate resolution of these legal matters could have a material adverse effect on Synovus' results of operations or financial condition for any particular period.

During the second quarter of 2023, Synovus updated its internal management reporting structure to transfer Capital Markets activities and related personnel from the Financial Management Services segment to the Wholesale Banking segment. Accordingly, its operating segment reporting structure was also updated. Synovus has four major reportable business segments: Wholesale Banking, Community Banking, Consumer Banking, and Financial Management Services, with functional activities such as treasury, technology, operations, marketing, finance, enterprise risk, legal, human resources, corporate communications, executive management, among others, included in Treasury and Corporate Other. Business segment results are determined based upon Synovus' management reporting system, which assigns balance sheet and income statement items to each of the business segments. Certain assets, liabilities, revenue, and expense not allocated or attributable to a particular business segment are included in Treasury and Corporate Other. Synovus's third-party consumer loans and loans held for sale, PPP loans, as well as CIB are included in Treasury and Corporate Other. The management accounting policies and processes utilized in compiling segment financial information are highly subjective and, unlike financial accounting, are not based on authoritative guidance similar to GAAP. As a result, reported segment results are not necessarily comparable with similar information reported by other financial institutions. The Wholesale Banking business segment serves primarily larger corporate and governmental clients by providing commercial lending, capital markets, deposit, and capital markets services through specialty teams including middle market, CRE, senior housing, national accounts, premium finance, structured lending, healthcare, asset-based lending, public finance, restaurant services, community investment capital, and capital markets. The Community Banking business segment primarily serves small and medium-sized commercial clients as well as individual private wealth clients using a relationship-based approach. The commercial component of this segment focuses on locally owned and operated businesses. Private wealth services are delivered to the individuals operating the businesses as well as other individuals in the communities in which the Community Bank operates. A comprehensive set of banking products are offered to the client set, including a full suite of lending, payments, and depository products as well as financial planning services. The Consumer Banking business segment serves individual and small business clients through its branch and ATM network, in addition to digital and telephone channels. This segment provides individuals and small businesses with an array of comprehensive banking products and services, including depository accounts, credit and debit cards, payment solutions, goal-based planning, home equity and other consumer loans, and small business lending solutions. The Financial Management Services business segment serves its clients by providing mortgage, trust services, professional portfolio management for fixed-income securities, securities underwriting and distribution, the execution of securities transactions as a broker/dealer, asset management, financial planning, and family office services, as well as the provision of individual investment advice on equity and other securities. Synovus uses a centralized FTP methodology to attribute appropriate net interest income to the business segments. The intent of the FTP methodology is to transfer interest rate risk from the business segments by providing matched duration funding of assets and liabilities. The result is to centralize the financial impact, management, and reporting of interest rate risk in the Treasury and Corporate Other function, where it can be centrally monitored and managed. Treasury and Corporate Other includes certain assets and/or liabilities managed within that function. Additionally, Treasury and Corporate Other also charges (credits) an internal cost of funds for assets held in (or pays for funding provided by) each business segment. The process for determining FTP is based on a number of factors and assumptions, including prevailing market interest rates, the expected lives of various assets and liabilities, and the Company's broader funding profile. The following tables present certain financial information for each reportable business segment for the three and six months ended June 30, 2023 and 2022. The application and development of management reporting methodologies is a dynamic process and is subject to periodic enhancements. As these enhancements are made, financial results presented by each reportable business segment may be periodically revised. Loan and deposit transfers occur from time to time between reportable business segments primarily to maintain the migration of clients and relationship managers between segments. Prior periods have been adjusted accordingly.

Subsequent Events [Abstract]
Subsequent Events	Note 11 - Subsequent Events Pending sale of medical office loans On July 19, 2023, Synovus signed a purchase and sale agreement to sell approximately $1.3 billion of medical office loans; accordingly, a charge-off of the existing ACL of approximately $23 million has been recorded, and the loans have been reclassified to other loans held-for-sale subsequent to the end of the second quarter of 2023. The transaction is expected to result in an after-tax net loss of approximately $25 million that represents the difference between the amortized cost and the estimated value of the loan proceeds. Voluntary Early Retirement Program In July 2023, Synovus incurred approximately $19 million in one-time termination benefits, recorded as restructuring charges, associated with a voluntary early retirement program offered to certain qualified employees. Execution of third-party consumer loans sale On July 25, 2023, Synovus sold approximately $316 million of third-party consumer loans held for sale, with the remaining $22 million of the portfolio expected to settle in the third quarter of 2023. Synovus previously recognized a $19.1 million year-to-date loss as of June 30, 2023.

Investments in Tax Credit Structures	Investments in Tax Credit Structures Synovus invests in certain LIHTC partnerships, which are engaged in the development and operation of affordable multi-family housing pursuant to Section 42 of the Code. Additionally, Synovus invests in certain new market tax credit partnerships pursuant to Section 45D of the Code, certain HTCs pursuant to Section 47 of the Code, and certain solar energy tax credit partnerships pursuant to Section 48 of the Code. Synovus typically acts as a limited partner in these investments and does not exert control over the operating or financial policies of the partnerships and as such, is not considered the primary beneficiary of the partnership. For certain of its LIHTC investments, Synovus provides financing during the construction and development of the properties and is at risk for the funded amount of its equity investment plus the outstanding amount of any construction loans in excess of the fair value of the collateral for the loan, but has no obligation to fund the operations or working capital of the partnerships and is not exposed to losses beyond Synovus’ investment. Synovus receives tax credits related to these investments, which are subject to recapture by taxing authorities based on compliance provisions required to be met at the project level.
Reclassifications	Reclassifications Prior periods' consolidated financial statements are reclassified whenever necessary to conform to the current periods' presentation.
Use of Estimates in the Preparation of Financial Statements	Use of Estimates in the Preparation of Financial Statements In preparing the consolidated financial statements in accordance with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the respective consolidated balance sheets and the reported amounts of revenue and expense for the periods presented. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the ACL, estimates of fair value, income taxes, and contingent liabilities.
