Significant Accounting Policies [Abstract]
Significant Accounting Policies	Note 1 - Significant Accounting Policies Business Operations The accompanying unaudited interim consolidated financial statements of Synovus include the accounts of the Parent Company and its consolidated subsidiaries. Synovus provides integrated financial services including commercial and retail banking, financial management, insurance and mortgage services to customers through locally-branded divisions of its wholly-owned subsidiary bank, Synovus Bank, in offices located in Georgia, Alabama, South Carolina, Florida, and Tennessee. In addition to our banking operations, we also provide various other financial services to our customers through direct and indirect wholly-owned non-bank subsidiaries, including: Synovus Securities, Inc., headquartered in Columbus, Georgia, which specializes in professional portfolio management for fixed-income securities, investment banking, the execution of securities transactions as a broker/dealer and the provision of individual investment advice on equity and other securities; Synovus Trust Company, N.A., headquartered in Columbus, Georgia, which provides trust, asset management and financial planning services; and Synovus Mortgage Corp., headquartered in Birmingham, Alabama, which offers mortgage services. Basis of Presentation 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, 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' 2014 Form 10-K. There have been no significant changes to the accounting policies as disclosed in Synovus' 2014 Form 10-K. In preparing the unaudited interim 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 revenues and expenses 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 allowance for loan losses; the valuation of other real estate; the fair value of investment securities; the fair value of private equity investments; contingent liabilities related to legal matters; and the deferred tax assets valuation allowance. Cash and Cash Equivalents Cash and cash equivalents consist of cash and due from banks. At June 30, 2015 , no amount of the due from banks balance was restricted as to withdrawal. At December 31, 2014 , $125 thousand of the due from banks balance was restricted as to withdrawal. Short-term Investments Short-term investments consist of interest bearing funds with the Federal Reserve Bank, interest earning deposits with banks, and Federal funds sold and securities purchased under resale agreements. At June 30, 2015 and December 31, 2014 , interest bearing funds with the Federal Reserve Bank included $123.1 million and $89.7 million , respectively, on deposit to meet Federal Reserve Bank requirements. Interest earning deposits with banks include $6.6 million and $7.1 million at June 30, 2015 and December 31, 2014 , respectively, which is pledged as collateral in connection with certain letters of credit. Federal funds sold include $68.1 million and $67.5 million at June 30, 2015 and December 31, 2014 , respectively, which are pledged to collateralize certain derivative instruments. Federal funds sold and securities purchased under resale agreements, and Federal funds purchased and securities sold under repurchase agreements, generally mature in one day. Recently Adopted Accounting Standards Updates During 2014, the FASB issued the following ASUs, all of which became effective January 1, 2015: • ASU 2014-01, Investments-Equity Method and Joint Ventures (Topic 323), Accounting for Investments in Qualified Affordable Housing Projects In January 2014, the FASB issued amended guidance which permits Synovus to make an accounting policy election to account for its investments in qualified affordable housing projects using a proportional amortization method, if certain conditions are met, and to present the amortization as a component of income tax expense. The amended guidance would be applied retrospectively to all periods presented and is effective for fiscal years, and interim periods within those years, beginning after December 15, 2014. Regardless of the policy election, the amended guidance, where disclosed, enables the users of the financial statements to understand the nature of investments in qualified affordable housing projects and the effect of the measurement of the investments in qualified affordable housing projects and the related tax credits on Synovus’ financial position and results of operations. Synovus adopted the amended guidance on January 1, 2015, and did not make an accounting policy election to apply the proportional amortization method for its investments in qualified affordable housing projects because the impact to the consolidated financial statements was insignificant. Therefore, the adoption did not have an impact on Synovus’ consolidated financial statements.

At June 30, 2015 and December 31, 2014 , investment securities with a carrying value of $2.22 billion and $2.12 billion respectively, were pledged to secure certain deposits and securities sold under repurchase agreements as required by law and contractual agreements. Synovus has reviewed investment securities that are in an unrealized loss position as of June 30, 2015 and December 31, 2014 for OTTI and does not consider any securities in an unrealized loss position to be other-than-temporarily impaired. If Synovus intended to sell a security in an unrealized loss position, the entire unrealized loss would be reflected in income. Synovus does not intend to sell investment securities in an unrealized loss position prior to the recovery of the unrealized loss, which may 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. Declines in the fair value of available for sale securities below their cost that are deemed to have OTTI are reflected in earnings as realized losses to the extent the impairment is related to credit losses. The amount of the impairment related to other factors is recognized in other comprehensive income. Currently, unrealized losses on debt securities are attributable to increases in interest rates on comparable securities from the date of purchase. Synovus regularly evaluates its investment securities portfolio to ensure that there are no conditions that would indicate that unrealized losses represent OTTI. These factors include the length of time the security has been in a loss position, the extent that the fair value is below amortized cost, and the credit standing of the issuer. As of June 30, 2015 , Synovus had thirty-seven investment securities in a loss position for less than twelve months and thirty-two investment securities in a loss position for twelve months or longer. Gross unrealized losses on investment securities and the fair value of the related securities, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position, at June 30, 2015 and December 31, 2014 , are presented below.

(2) Total before net deferred fees and costs of $30.8 million . The credit quality of the loan portfolio is summarized no less frequently than quarterly 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 classified 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. In the following tables, retail 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 Uniform Retail Credit Classification and Account Management Policy. Additionally, in accordance with the Interagency Supervisory Guidance on Allowance for Loan and Lease Losses Estimation Practices for Loans and Lines of Credit Secured by Junior Liens on 1-4 Family Residential Properties, the risk grade classifications of retail loans (home equity lines and consumer mortgages) secured by junior liens on 1-4 family residential properties also consider available information on the payment status of the associated senior lien with other financial institutions.

Excluding accruing TDRs, there was no interest income recognized for the investment in impaired loans for the six and three months ended June 30, 2014 . Interest income recognized for accruing TDRs was $8.0 million and $4.0 million for the six and three months ended June 30, 2014 . At June 30, 2015 and December 31, 2014 , all impaired loans other than $268.5 million and $348.4 million , respectively, of accruing TDRs, were on non-accrual status. Concessions provided in a TDR are primarily in the form of providing a below market interest rate given the borrower's credit risk, a period of time generally less than one year with a reduction of required principal and/or interest payments (e.g., interest only for a period of time), or extension of the maturity of the loan generally for less than one year. Insignificant periods of reduction of principal and/or interest payments, or one-time deferrals of 3 months or less, are generally not considered to be financial concessions. The following tables represent, by concession type, the post-modification balance for loans modified or renewed during the six and three months ended June 30, 2015 and 2014 that were reported as accruing or non-accruing TDRs.

If, at the time a loan was designated as a TDR, the loan was not already impaired, the measurement of impairment that resulted from the TDR designation changes from a general pool-level reserve to a specific loan measurement of impairment in accordance with ASC 310-10-35. Generally, the change in the allowance for loan losses resulting from such TDR designation is not significant. At June 30, 2015 , the allowance for loan losses allocated to accruing TDRs totaling $268.5 million was $15.3 million compared to accruing TDRs of $348.4 million with an allocated allowance for loan losses of $21.0 million at December 31, 2014 . Non-accrual, non-homogeneous loans (commercial-type impaired loans greater than $1 million ) that are designated as TDRs, are individually measured for the amount of impairment, if any, both before and after the TDR designation.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill	Note 8 - Goodwill At June 30, 2015, the carrying value of goodwill was $24.4 million . Synovus assesses goodwill for impairment at the reporting unit level on an annual basis and between annual assessments if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Synovus performs its annual goodwill impairment testing as of June 30 th of each year. At June 30, 2015, Synovus completed its annual goodwill impairment evaluation, and as a result of this evaluation, concluded that goodwill was not impaired. For the goodwill impairment test, the fair value of the reporting unit was determined by using the income approach. The first step (Step 1) of impairment testing requires a comparison of the reporting unit's fair value to the carrying amount to identify potential impairment. The result of the Step 1 process indicated that goodwill of the reporting unit was not impaired, as the fair value of the reporting unit exceeded the respective carrying value; therefore, no further testing was required. The estimated fair value of the reporting unit was $125.7 million , which exceeded the carrying value of $83.7 million by $42.0 million , or 50% . The key assumptions that drove the fair value of this reporting unit under the income approach included projected revenue growth, projected EBITDA margin, long-term growth rate, and the discount rate.

During the years 2010 and 2011, Synovus recorded a deferred tax asset valuation allowance associated with unrealized gains and losses not recognized in income directly to other comprehensive income (loss) by applying the portfolio approach for allocation of the valuation allowance. Synovus has consistently applied the portfolio approach which treats derivative financial instruments, equity securities, and debt securities as a single portfolio. As of June 30, 2015 , the balance in net unrealized gains (losses) on cash flow hedges and net unrealized gains (losses) on investment securities available for sale includes unrealized losses of $12.1 million and $13.3 million , respectively, related to the residual tax effects remaining in OCI due to a previously established deferred tax asset valuation allowance. Under the portfolio approach, these unrealized losses are realized at the time the entire portfolio is sold or disposed. The following table illustrates activity within the reclassifications out of accumulated other comprehensive income (loss), for the six and three months ended June 30, 2015 and 2014 .

Fair Value Accounting

Fair Value Accounting	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Accounting	Note 10 - Fair Value Accounting Synovus carries various assets and liabilities at fair value based on the fair value accounting guidance under ASC 820, Fair Value Measurements , and ASC 825, Financial Instruments . Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an “exit price”) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Fair Value Hierarchy Synovus determines the fair value of its financial instruments based on the fair value hierarchy established under ASC 820-10, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the financial instrument's fair value measurement in its entirety. There are three levels of inputs that may be used to measure fair value. The three levels of inputs of the valuation hierarchy are defined below: Level 1 Quoted prices (unadjusted) in active markets for identical assets and liabilities for the instrument or security to be valued. Level 1 assets include marketable equity securities, U.S. Treasury securities, and mutual funds. Level 2 Observable inputs other than Level 1 quoted prices, such as quoted prices for similar assets and liabilities in active markets, quoted prices in markets that are not active or model-based valuation techniques for which all significant assumptions are derived principally from or corroborated by observable market data. Level 2 assets and liabilities include debt securities with quoted prices that are traded less frequently than exchange-traded instruments and derivative contracts whose value is determined by using a pricing model with inputs that are observable in the market or can be derived principally from or corroborated by observable market data. U.S. Government sponsored agency securities, mortgage-backed securities issued by U.S. Government sponsored enterprises and agencies, obligations of states and municipalities, collateralized mortgage obligations issued by U.S. Government sponsored enterprises, and mortgage loans held-for-sale are generally included in this category. Certain private equity investments that invest in publicly traded companies are also considered Level 2 assets. Level 3 Unobservable inputs that are supported by little, if any, market activity for the asset or liability. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow models and similar techniques, and may also include the use of market prices of assets or liabilities that are not directly comparable to the subject asset or liability. These methods of valuation may result in a significant portion of the fair value being derived from unobservable assumptions that reflect Synovus' own estimates for assumptions that market participants would use in pricing the asset or liability. This category primarily includes collateral-dependent impaired loans, other real estate, certain equity investments, and private equity investments. See Note 16 "Fair Value Accounting" to the consolidated financial statements of Synovus' 2014 Form 10-K for a description of valuation methodologies for assets and liabilities measured at fair value on a recurring and non-recurring basis. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following table presents all financial instruments measured at fair value on a recurring basis as of June 30, 2015 and December 31, 2014, according to the valuation hierarchy included in ASC 820-10. For equity and debt securities, class was determined based on the nature and risks of the investments. Transfers betweens levels for the period ended June 30, 2015 and December 31, 2014 were inconsequential. June 30, 2015 (in thousands) Level 1 Level 2 Level 3 Total Assets and Liabilities at Fair Value Assets Trading securities: Mortgage-backed securities issued by U.S. Government agencies — 1,011 — 1,011 Collateralized mortgage obligations issued by U.S. Government sponsored enterprises — 7,193 — 7,193 State and municipal securities — 156 — 156 All other mortgage-backed securities — 2,416 — 2,416 Other investments — 1,197 — 1,197 Total trading securities $ — 11,973 — 11,973 Mortgage loans held for sale — 98,202 — 98,202 Investment securities available for sale: U.S. Treasury securities 43,532 — — 43,532 U.S. Government agency securities — 25,268 — 25,268 Securities issued by U.S. Government sponsored enterprises — 127,867 — 127,867 Mortgage-backed securities issued by U.S. Government agencies — 178,074 — 178,074 Mortgage-backed securities issued by U.S. Government sponsored enterprises — 2,410,729 — 2,410,729 Collateralized mortgage obligations issued by U.S. Government agencies or sponsored enterprises — 537,268 — 537,268 State and municipal securities — 4,685 — 4,685 Equity securities 7,603 — — 7,603 Other investments (1) 3,047 14,900 1,700 19,647 Total investment securities available for sale $ 54,182 3,298,791 1,700 3,354,673 Private equity investments — 1,033 26,959 27,992 Mutual funds held in rabbi trusts 11,218 — — 11,218 Derivative assets: Interest rate contracts — 27,948 — 27,948 Mortgage derivatives (2) — 2,691 — 2,691 Total derivative assets $ — 30,639 — 30,639 Liabilities Trading account liabilities — 1,546 — 1,546 Derivative liabilities: Interest rate contracts — 28,566 — 28,566 Visa derivative — — 1,415 1,415 Total derivative liabilities $ — 28,566 1,415 29,981 December 31, 2014 (in thousands) Level 1 Level 2 Level 3 Total Assets and Liabilities at Fair Value Assets Trading securities: Mortgage-backed securities issued by U.S. Government agencies — 145 — 145 Collateralized mortgage obligations issued by U.S. Government sponsored enterprises — 2,449 — 2,449 State and municipal securities — 1,976 — 1,976 All other mortgage-backed securities — 2,483 — 2,483 Other investments — 6,810 — 6,810 Total trading securities $ — 13,863 — 13,863 Mortgage loans held for sale — 63,328 — 63,328 Investment securities available for sale: U.S. Treasury securities 42,826 — — 42,826 U.S. Government agency securities — 27,324 — 27,324 Securities issued by U.S. Government sponsored enterprises — 82,042 — 82,042 Mortgage-backed securities issued by U.S. Government agencies — 179,816 — 179,816 Mortgage-backed securities issued by U.S. Government sponsored enterprises — 2,261,681 — 2,261,681 Collateralized mortgage obligations issued by U.S. Government agencies or sponsored enterprises — 417,076 — 417,076 State and municipal securities — 5,206 — 5,206 Equity securities 6,748 — — 6,748 Other investments (1) 2,035 15,007 1,645 18,687 Total investment securities available for sale $ 51,609 2,988,152 1,645 3,041,406 Private equity investments — 995 27,367 28,362 Mutual funds held in rabbi trusts 11,252 — — 11,252 Derivative assets: Interest rate contracts — 30,904 — 30,904 Mortgage derivatives (2) — 1,213 — 1,213 Total derivative assets $ — 32,117 — 32,117 Liabilities Trading account liabilities — 2,100 — 2,100 Salary stock units 1,206 — — 1,206 Derivative liabilities: Interest rate contracts — 31,398 — 31,398 Mortgage derivatives (2) — 753 — 753 Visa derivative — — 1,401 1,401 Total derivative liabilities $ — 32,151 1,401 33,552 (1) Based on an analysis of the nature and risks of these investments, Synovus has determined that presenting these investments as a single asset class is appropriate. (2) Mortgage derivatives consist of customer interest rate lock commitments that relate to the potential origination of mortgage loans, which would be classified as held for sale and forward loan sales commitments with third-party investors. Fair Value Option The following table summarizes the difference between the fair value and the unpaid principal balance of mortgage loans held for sale measured at fair value and the changes in fair value of these loans. Mortgage loans held for sale are initially measured at fair value with subsequent changes in fair value recognized in earnings. Changes in fair value were recorded as a component of mortgage banking income in the consolidated statements of income. An immaterial portion of these changes in fair value was attributable to changes in instrument-specific credit risk.

The table below includes a roll-forward of the amounts on the consolidated balance sheet for the six and three months ended June 30, 2015 and 2014 (including the change in fair value), for financial instruments of a material nature that are classified by Synovus within Level 3 of the fair value hierarchy and are measured at fair value on a recurring basis. Transfers between fair value levels are recognized at the end of the reporting period in which the associated changes in inputs occur. During the first and second quarters of 2015 and 2014, Synovus did not have any transfers between levels in the fair value hierarchy.

These non-recurring fair value adjustments typically are a result of the application of lower of cost or fair value accounting or a write-down occurring during the period. For example, if the fair value of an asset in these categories falls below its cost basis, it is considered to be at fair value at the end of the period of the adjustment. The following table presents assets measured at fair value on a non-recurring basis as of the dates indicated for which there was a fair value adjustment during the period.

Quantitative Information about Level 3 Fair Value Measurements The tables below provide an overview of the valuation techniques and significant unobservable inputs used in those techniques to measure financial instruments that are classified within Level 3 of the valuation hierarchy. The range of sensitivities that management utilized in its fair value calculations is deemed acceptable in the industry with respect to the identified financial instruments. The tables below present both the total balance as of the dates indicated for assets measured at fair value on a recurring basis and the assets measured at fair value on a non-recurring basis for which there was a fair value adjustment during the period.

(2) Represents management's estimate of discount that market participants would require based on the instrument's lack of liquidity. (3) Synovus also makes adjustments to the values of the assets listed above for various reasons, including age of the appraisal, information known by management about the property, such as occupancy rates, changes to the physical conditions of the property, pending sales, and other factors. Sensitivity Analysis of Level 3 Unobservable Inputs Measured on a Recurring Basis Included in the fair value estimates of financial instruments carried at fair value on the consolidated balance sheet are those estimated in full or in part using valuation techniques based on assumptions that are not supported by observable market prices, rates, or other inputs. Unobservable inputs are assessed carefully, considering the current economic environment and market conditions. However, by their very nature, unobservable inputs imply a degree of uncertainty in their determination, because they are supported by little, if any, market activity for the related asset or liability. Investment Securities Available for Sale The significant unobservable inputs used in the fair value measurement of the corporate obligations in Level 3 assets are the credit spread embedded in the discount rate and the discount for lack of liquidity. Generally, a change in one or more assumptions, and the degree or sensitivity of the change used, can have a significant impact on fair value. With regard to the trust preferred securities in Level 3 assets, raising the credit spread, and raising the discount for lack of liquidity assumptions will result in a lower fair value measurement. Private Equity Investments In the absence of quoted market prices, inherent lack of liquidity, and the long-term nature of private equity investments, significant judgment is required to value these investments. The significant unobservable inputs used in the fair value measurement of private equity investments include current operations, financial condition, and cash flows, comparables and private sales, when available, and recently executed financing transactions related to investee companies. Significant increases or decreases in any of these inputs in isolation would result in a significantly lower or higher fair value measurement. Visa Derivative Liability The fair value of the Visa derivative contract is determined based on management's estimate of the timing and amount of the Covered Litigation settlement, and the resulting payments due to the counterparty under the terms of the contract. Significant changes in any of these inputs in isolation could result in a significantly higher (lower) valuation of the Visa derivative liability. Also, additional funding into the escrow generally results in a proportional increase in our derivative liability. Fair Value of Financial Instruments The following table presents the carrying and fair values of financial instruments at June 30, 2015 and December 31, 2014 . The fair value represents management’s best estimates based on a range of methodologies and assumptions. For financial instruments that are not recorded at fair value on the balance sheet, such as loans, interest bearing deposits (including brokered deposits), and long-term debt, the fair value amounts should not be taken as an estimate of the amount that would be realized if all such financial instruments were to be settled immediately. The carrying and estimated fair values of financial instruments, as well as the level within the fair value hierarchy, as of June 30, 2015 and December 31, 2014 are as follows: June 30, 2015 (in thousands) Carrying Value Fair Value Level 1 Level 2 Level 3 Financial assets Cash and cash equivalents $ 360,832 360,832 360,832 — — Interest bearing funds with Federal Reserve Bank 1,289,205 1,289,205 1,289,205 — — Interest earning deposits with banks 18,694 18,694 18,694 — — Federal funds sold and securities purchased under resale agreements 72,487 72,487 72,487 — — Trading account assets 11,973 11,973 — 11,973 — Mortgage loans held for sale 98,202 98,202 — 98,202 — Investment securities available for sale 3,354,673 3,354,673 54,182 3,298,791 1,700 Private equity investments 27,992 27,992 — 1,033 26,959 Mutual funds held in rabbi trusts 11,218 11,218 11,218 — — Loans, net of deferred fees and costs 21,494,869 21,310,531 — — 21,310,531 Derivative assets 30,639 30,639 — 30,639 — Financial liabilities Trading account liabilities 1,546 1,546 — 1,546 — Non-interest bearing deposits 6,421,815 6,421,815 — 6,421,815 — Interest bearing deposits 16,227,366 16,238,771 — 16,238,771 — Federal funds purchased and securities sold under repurchase agreements 188,285 188,285 188,285 — — Long-term debt 2,139,219 2,200,777 — 2,200,777 — Derivative liabilities $ 29,981 29,981 — 28,566 1,415 December 31, 2014 (in thousands) Carrying Value Fair Value Level 1 Level 2 Level 3 Financial assets Cash and cash equivalents $ 485,489 485,489 485,489 — — Interest bearing funds with Federal Reserve Bank 721,362 721,362 721,362 — — Interest earning deposits with banks 11,810 11,810 11,810 — — Federal funds sold and securities purchased under resale agreements 73,111 73,111 73,111 — — Trading account assets 13,863 13,863 — 13,863 — Mortgage loans held for sale 63,328 63,328 — 63,328 — Other loans held for sale 3,606 3,606 — — 3,606 Investment securities available for sale 3,041,406 3,041,406 51,609 2,988,152 1,645 Private equity investments 28,362 28,362 — 995 27,367 Mutual funds held in rabbi trusts 11,252 11,252 11,252 — — Loans, net of deferred fees and costs 21,097,699 20,872,939 — — 20,872,939 Derivative assets 32,117 32,117 — 32,117 — Financial liabilities Trading account liabilities 2,100 2,100 — 2,100 — Non-interest bearing deposits 6,228,472 6,228,472 — 6,228,472 — Interest bearing deposits 15,303,228 15,299,372 — 15,299,372 — Federal funds purchased and securities sold under repurchase agreements 126,916 126,916 126,916 — — Salary stock units 1,206 1,206 1,206 — — Long-term debt 2,140,319 2,191,279 — 2,191,279 — Derivative liabilities $ 33,553 33,553 — 32,151 1,401

Derivative Instruments

Summary of Derivative Instruments [Abstract]
Derivative Instruments	Note 11 - Derivative Instruments As part of its overall interest rate risk management activities, Synovus utilizes derivative instruments to manage its exposure to various types of interest rate risk. These derivative instruments generally consist of interest rate swaps, interest rate lock commitments made to prospective mortgage loan customers, and commitments to sell fixed-rate mortgage loans. Interest rate lock commitments represent derivative instruments since it is intended that such loans will be sold. Synovus may also utilize interest rate swaps to manage interest rate risks primarily arising from its core banking activities. These interest rate swap transactions generally involve the exchange of fixed and floating interest rate payment obligations without the exchange of underlying principal amounts. Swaps may be designated as either cash flow hedges or fair value hedges, as discussed below. As of June 30, 2015 and December 31, 2014, Synovus had no outstanding interest rate swap contracts utilized to manage interest rate risk. 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. 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 and other market indicators. 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 customer 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, customer credit rating, collateral value, and customer 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 customer specific risk. Cash Flow Hedges Synovus designates hedges of floating rate loans as cash flow hedges. These swaps hedge against the variability of cash flows from specified pools of floating rate prime based loans. Synovus calculates effectiveness of the hedging relationship quarterly using regression analysis. The effective portion of the gain or loss on the derivative instrument is reported as a component of other comprehensive income and reclassified into earnings in the same period or periods during which the hedged transactions affect earnings. Ineffectiveness from cash flow hedges is recognized in the consolidated statements of income as a component of other non-interest income. As of June 30, 2015 , there were no cash flow hedges outstanding, and therefore, no cumulative ineffectiveness. Synovus expects to reclassify from accumulated other comprehensive income (loss) $447 thousand of interest expense during the next twelve months as amortization of deferred losses is recorded. Synovus did not terminate any cash flow hedges during 2015 or 2014 . The remaining unamortized deferred net loss balance of all previously terminated cash flow hedges at June 30, 2015 and December 31, 2014 was $(894) thousand and $(1.1) million , respectively. Fair Value Hedges Synovus designates hedges of fixed rate liabilities as fair value hedges. These swaps hedge against the change in fair value of various fixed rate liabilities due to changes in the benchmark interest rate, LIBOR. Synovus calculates effectiveness of the fair value hedges quarterly using regression analysis. Ineffectiveness from fair value hedges is recognized in the consolidated statements of income as a component of other non-interest income. As of June 30, 2015 , there were no fair value hedges outstanding, and therefore, no cumulative ineffectiveness. Synovus did not terminate any fair value hedges during 2015 or 2014 . The remaining unamortized deferred gain balance on all previously terminated fair value hedges at June 30, 2015 and December 31, 2014 was $6.1 million and $7.6 million , respectively. Synovus expects to reclassify from hedge-related basis adjustment, a component of long-term debt, $3.1 million of the deferred gain balance on previously terminated fair value hedges as a reduction to interest expense during the next twelve months as amortization of deferred gains is recorded. Customer Related Derivative Positions Synovus enters into interest rate swap agreements to facilitate the risk management strategies of a small number of commercial banking customers. Synovus mitigates this risk by entering into equal and offsetting interest rate swap agreements with highly rated third-party financial institutions. The interest rate swap agreements are free-standing derivatives and are recorded at fair value on Synovus' consolidated balance sheet. Fair value changes are recorded in non-interest income in Synovus' consolidated statements of income. As of June 30, 2015 , the notional amount of customer related interest rate derivative financial instruments, including both the customer position and the offsetting position, was $1.10 billion , an increase of $13.9 million compared to December 31, 2014 . Visa Derivative In conjunction with the sale of Class B shares of common stock issued by Visa to Synovus as a Visa USA member, Synovus entered into a derivative contract with the purchaser, which provides for settlements between the parties based upon a change in the ratio for conversion of Visa Class B shares to Visa Class A shares. The conversion ratio changes when Visa deposits funds to a litigation escrow established by Visa to pay settlements for certain litigation, for which Visa is indemnified by Visa USA members. The litigation escrow is funded by proceeds from Visa’s conversion of Class B shares. The fair value of the derivative contract was $1.4 million at both June 30, 2015 and December 31, 2014. The fair value of the derivative contract is determined based on management's estimate of the timing and amount of the Covered Litigation settlement, and the resulting payments due to the counterparty under the terms of the contract. Mortgage Derivatives Synovus originates first lien residential mortgage loans for sale into the secondary market. Mortgage loans are sold by Synovus for conversion to securities and the servicing of these loans is generally sold to a third-party servicing aggregator, or Synovus sells the mortgage loans as whole loans to investors either individually or in bulk on a servicing released basis. Synovus enters into interest rate lock commitments for residential mortgage loans which commits it to lend funds to a potential borrower at a specific interest rate and within a specified period of time. Interest rate lock commitments that relate to the origination of mortgage loans that, if originated, will be held for sale, are considered derivative financial instruments under applicable accounting guidance. Outstanding interest rate lock commitments expose Synovus to the risk that the price of the mortgage loans underlying the commitments may decline due to increases in mortgage interest rates from inception of the rate lock to the funding of the loan. At June 30, 2015 and December 31, 2014 , Synovus had commitments to fund at a locked interest rate, primarily fixed-rate mortgage loans to customers in the amount of $108.5 million and $73.4 million , respectively. The fair value of these commitments resulted in a gain of $266 thousand and $ 1.3 million for the six months ended June 30, 2015 and 2014 , respectively, which was recorded as a component of mortgage banking income in the consolidated statements of income. At June 30, 2015 and December 31, 2014 , outstanding commitments to sell primarily fixed-rate mortgage loans amounted to $149.5 million and $113.0 million , respectively. Such commitments are entered into to reduce the exposure to market risk arising from potential changes in interest rates, which could affect the fair value of mortgage loans held for sale and outstanding rate lock commitments, which guarantee a certain interest rate if the loan is ultimately funded or granted by Synovus as a mortgage loan held for sale. The commitments to sell mortgage loans are at fixed prices and are scheduled to settle at specified dates that generally do not exceed 90 days. The fair value of outstanding commitments to sell mortgage loans resulted in a gain of $2.0 million and a loss of $ (2.0) million for the six months ended June 30, 2015 and 2014 , respectively, which was recorded as a component of mortgage banking income in the consolidated statements of income. Collateral Contingencies Certain derivative instruments contain provisions that require Synovus to maintain an investment grade credit rating from each of the major credit rating agencies. When Synovus’ credit rating falls below investment grade, these provisions allow the counterparties of the derivative instrument to demand immediate and ongoing full collateralization on derivative instruments in net liability positions and, for certain counterparties, request immediate termination. As Synovus’ current rating is below investment grade, Synovus is required to post collateral, as required by each agreement, against these positions. Additionally, as of June 10, 2013, the CCC became mandatory for certain trades as required under the Dodd-Frank Act. These derivative transactions also carry collateral requirements, both at the inception of the trade, and as the value of each derivative position changes. As trades are migrated to the CCC, dealer counterparty exposure will be reduced, and higher notional amounts of Synovus' derivative instruments will be housed at the CCC, a highly regulated and well-capitalized entity. As of June 30, 2015 , collateral totaling $68.1 million consisting of Federal funds sold was pledged to the derivative counterparties, including $8.2 million with the CCC, to comply with collateral requirements. The impact of derivative instruments on the consolidated balance sheets at June 30, 2015 and December 31, 2014 is presented below.

(2) Gain (loss) represents net fair value adjustments recorded for interest rate lock commitments and commitments to sell mortgage loans to third-party investors. During the six months ended June 30, 2015 and 2014 , Synovus reclassified $1.5 million from hedge-related basis adjustment, a component of long-term debt, as a reduction to interest expense. These deferred gains relate to hedging relationships that have been previously terminated and are reclassified into earnings over the remaining life of the hedged items.

Net Income Per Common Share	Note 12 - Net Income Per Common Share The following table displays a reconciliation of the information used in calculating basic and diluted earnings per common share for the six and three months ended June 30, 2015 and 2014 . Six Months Ended June 30, Three Months Ended June 30, (in thousands, except per share data) 2015 2014 2015 2014 Basic Net Income Per Common Share: Net income available to common shareholders $ 104,637 90,170 $ 53,233 44,313 Weighted average common shares outstanding 133,935 138,961 132,947 138,991 Net income per common share, basic $ 0.78 0.65 0.40 0.32 Diluted Net Income Per Common Share: Net income available to common shareholders $ 104,637 90,170 53,233 44,313 Weighted average common shares outstanding 133,935 138,961 132,947 138,991 Potentially dilutive shares from assumed exercise of securities or other contracts to purchase common stock 743 574 678 576 Weighted average diluted common shares 134,678 139,535 133,625 139,567 Net income per common share, diluted $ 0.78 0.65 0.40 0.32 Basic net income per common share is computed by dividing net income by the average common shares outstanding for the period. Diluted net income per common share reflects the dilution that could occur if securities or other contracts to issue common stock were exercised or converted. The dilutive effect of outstanding options and restricted share units is reflected in diluted net income per common share, unless the impact is anti-dilutive, by application of the treasury stock method. As of June 30, 2015 and 2014 , there were 2.7 million and 3.5 million , respectively, potentially dilutive shares related to common stock options and Warrants to purchase shares of common stock that were outstanding during 2015 and 2014 , but were not included in the computation of diluted net income per common share because the effect would have been anti-dilutive.

Share-based Compensation [Abstract]
Share-based Compensation	Note 13 - Share-based Compensation General Description of Share-based Plans Synovus has a long-term incentive plan under which the Compensation Committee of the Board of Directors has the authority to grant share-based awards to Synovus employees. At June 30, 2015 , Synovus had a total of 7.0 million shares of its authorized but unissued common stock reserved for future grants under the 2013 Omnibus Plan. The 2013 Omnibus Plan authorizes 8.6 million common share equivalents available for grant, where grants of options count as one share equivalent and grants of full value awards (e.g., restricted share units, market restricted share units, and performance share units) count as two share equivalents. Any restricted share units that are forfeited and options that expire unexercised will again become available for issuance under the Plan. The Plan permits grants of share-based compensation including stock options, restricted share units, market restricted share units, and performance share units. The grants generally include vesting periods ranging from three to five years and contractual terms of ten years. Stock options are granted at exercise prices which equal the fair value of a share of common stock on the grant-date. Synovus has historically issued new shares to satisfy share option exercises and share unit conversions. Dividend equivalents are paid on outstanding restricted share units, market restricted share units, and performance share units in the form of additional restricted share units that vest over the same vesting period or the vesting period left on the original restricted share unit grant. Share-based Compensation Expense Share-based compensation costs associated with employee grants are recorded as a component of salaries and other personnel expense in the consolidated statements of income. Share-based compensation costs associated with grants made to non-employee directors of Synovus are recorded as a component of other operating expenses. Total share-based compensation expense was $6.3 million and $3.0 million for the six and three months ended June 30, 2015 , respectively, and $4.7 million and $2.5 million for the six and three months ended June 30, 2014 , respectively. Stock Options No stock option grants were made during the six months ended June 30, 2015 . At June 30, 2015 , there were 1.9 million outstanding options to purchase shares of common stock with a weighted average exercise price of $36.27 . Restricted Share Units, Performance Share Units, and Market Restricted Share Units During the six months ended June 30, 2015 , Synovus awarded 318 thousand restricted share units that have a service-based vesting period of three years and awarded 82 thousand performance share units that vest upon service and performance conditions. Synovus also granted 82 thousand market restricted share units during the six months ended June 30, 2015 . The weighted average grant-date fair value of the awarded restricted share units, performance share units and market restricted share units was $28.05 per share. Market restricted share units and performance share units are granted at target and are compared annually to required market and performance metrics. The performance share units vest upon meeting certain service and performance conditions. Return on average assets (ROAA) performance is evaluated each year over a three-year performance period, with share distribution determined at the end of the three years. The number of performance share units that will ultimately vest ranges from 0% to 150% of target based on Synovus' three-year weighted average ROAA (as defined). The market restricted share units have a three-year service-based vesting component as well as a total shareholder return multiplier. The number of market restricted share units that will ultimately vest ranges from 75% to 125% of target based on Synovus' total shareholder return (TSR). At June 30, 2015 , including dividend equivalents granted, there were 1.1 million restricted share units, performance share units and market restricted share units outstanding with a weighted average grant-date fair value of $24.91 .

Legal Proceedings

Legal Proceedings Disclosure [Abstract]
Legal Proceedings	Note 14 - 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 examinations, information gathering requests, inquiries and investigations. Synovus, like many other financial institutions, has been the target of numerous legal actions and other proceedings asserting claims for damages and related relief for losses resulting from the recent financial crisis. These actions include mortgage loan and other loan put-back claims, claims and counterclaims asserted by individual borrowers related to their loans and allegations of violations of state and federal laws and regulations relating to banking practices, including several purported 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 occurred. Synovus also from time to time faces disputes with customers and other counterparties, and in many cases, those disputes can pose both financial and reputational risk to Synovus. 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 accrual. 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, 2015 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, including those legal matters described below, Synovus considers whether it is able to estimate the total reasonably possible loss or range of loss. An event is "reasonably possible" if "the chance of the future event or events occurring is more than remote but less than likely." An event is "remote" if "the chance of the future event occurring is more than slight but less than reasonably possible." 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 pending and threatened litigation, including, without limitation, the matters described below, is from zero to $15 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 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 for any particular period. Synovus intends to vigorously pursue all available defenses to these legal matters, but will also consider other alternatives, including settlement, in situations where there is an opportunity to resolve such legal matters on terms that Synovus considers to be favorable, including in light of the continued expense, reputational risk and distraction of defending such legal matters. Synovus also maintains insurance coverage, which may (or may not) be available to cover legal fees, or potential losses that might be incurred in connection with the legal matters described below. The above-noted estimated range of reasonably possible losses does not take into consideration insurance coverage which may or may not be available for the respective legal matters. TelexFree Litigation On October 22, 2014, several pending lawsuits were consolidated into a multi-district putative class action case captioned In re: TelexFree Securities Litigation, MDL Number 4:14-md2566-TSH, United States District Court District of Massachusetts. Synovus Financial Corp. and Synovus Bank were named as defendants with numerous other defendants in the purported class action lawsuit. An Amended Complaint was filed on March 31, 2015 which consolidated and amended the claims previously asserted. The claims against Synovus Financial Corp. were dismissed by Plaintiffs on April 10, 2015 so now, as to Synovus-related entities, only claims against Synovus Bank remain pending. TelexFree was a merchant customer of Base Commerce, LLC “Base Commerce”, an independent sales organization/member service provider sponsored by Synovus Bank. The purported class action lawsuit generally alleges that TelexFree engaged in an improper multi-tier marketing scheme involving voice-over Internet protocol telephone services and that the various defendants, including Synovus Bank, provided financial services to TelexFree that allowed TelexFree to conduct its business operations. Synovus Bank filed a motion to dismiss the lawsuit on June 1, 2015. Synovus Bank believes it has substantial defenses related to these purported claims and intends to vigorously defend the claims asserted. Synovus currently cannot reasonably estimate losses attributable to this matter.

Significant Accounting Policies [Abstract]
Cash and Cash Equivalents	Cash and cash equivalents consist of cash and due from banks. At June 30, 2015 , no amount of the due from banks balance was restricted as to withdrawal.
Short-term Investment	Short-term investments consist of interest bearing funds with the Federal Reserve Bank, interest earning deposits with banks, and Federal funds sold and securities purchased under resale agreements.
Recently Adopted Accounting Standards Updates	During 2014, the FASB issued the following ASUs, all of which became effective January 1, 2015: • ASU 2014-01, Investments-Equity Method and Joint Ventures (Topic 323), Accounting for Investments in Qualified Affordable Housing Projects In January 2014, the FASB issued amended guidance which permits Synovus to make an accounting policy election to account for its investments in qualified affordable housing projects using a proportional amortization method, if certain conditions are met, and to present the amortization as a component of income tax expense. The amended guidance would be applied retrospectively to all periods presented and is effective for fiscal years, and interim periods within those years, beginning after December 15, 2014. Regardless of the policy election, the amended guidance, where disclosed, enables the users of the financial statements to understand the nature of investments in qualified affordable housing projects and the effect of the measurement of the investments in qualified affordable housing projects and the related tax credits on Synovus’ financial position and results of operations. Synovus adopted the amended guidance on January 1, 2015, and did not make an accounting policy election to apply the proportional amortization method for its investments in qualified affordable housing projects because the impact to the consolidated financial statements was insignificant. Therefore, the adoption did not have an impact on Synovus’ consolidated financial statements. At June 30, 2015, the aggregate carrying value of Synovus' investments in LIHTC partnerships was $9.9 million . See Note 18 "Variable Interest Entities" to the consolidated financial statements of Synovus' 2014 Form 10-K for additional information regarding these investments. Additionally, adoption of the following standards effective January 1, 2015 did not have a significant impact on Synovus’ consolidated financial statements. • ASU 2014-14, Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure • ASU 2014-12, Accounting for Share-Based Payments when the Terms of an Award Provide that a Performance Target Could be Achieved after the Requisite Service Period • ASU 2014-11, Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures • ASU 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity • ASU 2014-04, Receivables -Troubled Debt Restructurings by Creditors (Subtopic 310-40), Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure
Reclassifications	Prior periods' consolidated financial statements are reclassified whenever necessary to conform to the current periods' presentation.
Subsequent Events	Synovus has evaluated for consideration, or disclosure, all transactions, events, and circumstances, subsequent to the date of the consolidated balance sheet and through the date the accompanying unaudited interim consolidated financial statements were issued, and has reflected, or disclosed, those items deemed appropriate within the unaudited interim consolidated financial statements.

Changes in Fair Value Included in Consolidated Statements of Income	The following table summarizes the difference between the fair value and the unpaid principal balance of mortgage loans held for sale measured at fair value and the changes in fair value of these loans. Mortgage loans held for sale are initially measured at fair value with subsequent changes in fair value recognized in earnings. Changes in fair value were recorded as a component of mortgage banking income in the consolidated statements of income. An immaterial portion of these changes in fair value was attributable to changes in instrument-specific credit risk.
