Fair Value Disclosures [Abstract] |
Fair Value Measurement and Fair Value of Financial Instruments | Fair Value Measurement and Fair Value of Financial Instruments Under applicable accounting standards, the Company measures a portion of its assets and liabilities at fair value. These assets and liabilities are predominantly recorded at fair value on a recurring basis. At times, certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, they are subject to fair value adjustments only as required through the application of an accounting method such as lower of cost or fair value or write-down of individual assets. The Company categorizes its assets and liabilities into three levels based on the established fair value hierarchy and conducts a review of fair value hierarchy classifications on a quarterly basis. For more information regarding the fair value hierarchy and how the Company measures fair value, see Note 1 — Summary of Significant Accounting Policies — Significant Accounting Policies — Fair Value to the Consolidated Financial Statements in the Company’s 2024 Form 10-K. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following section describes the valuation methodologies used by the Company to measure financial assets and liabilities on a recurring basis, as well as the general classification of these instruments within the fair value hierarchy. Available-for-Sale Debt Securities — The fair value of AFS debt securities is generally determined by independent external pricing service providers who have experience in valuing these securities or by taking the average quoted market prices obtained from independent external brokers. The valuations provided by the third-party pricing service providers are based on observable market inputs, which include benchmark yields, reported trades, issuer spreads, benchmark securities, bids, offers, prepayment expectations and reference data obtained from market research publications. Inputs used by the third-party pricing service providers in valuing collateralized mortgage obligations and other securitization structures also include newly issued data, monthly payment information, whole loan collateral performance, tranche evaluation and “To Be Announced” prices. In valuing securities issued by state and political subdivisions, inputs used by third-party pricing service providers also include material event notices. The valuations provided by the brokers incorporate information from their trading desks, research and other market data. On a monthly basis, the Company validates the valuations provided by third-party pricing service providers to ensure that the fair value determination is consistent with the applicable accounting guidance and that the financial instruments are properly classified in the fair value hierarchy. To perform this validation, the Company evaluates the fair values of securities by comparing the fair values provided by the third-party pricing service providers to prices from other available independent sources for the same securities. When significant variances in prices are identified, the Company further compares the inputs used by different sources to ascertain the reliability of these sources. On a quarterly basis, the Company reviews the valuation inputs and methodology furnished by third-party pricing service providers for each security category. On an annual basis, the Company assesses the reasonableness of broker pricing by reviewing the related pricing methodologies. This review includes corroborating pricing with market data, performing pricing input reviews under current market-related conditions, and investigating security pricing by instrument as needed. When a quoted price in an active market exists for the identical security, this price is used to determine the fair value and the AFS debt security is classified as Level 1. Level 1 AFS debt securities consist of U.S. Treasury securities. When pricing is unavailable from third-party pricing service providers for certain securities, the Company requests market quotes from various independent external brokers and utilizes the average quoted market prices. In addition, the Company obtains market quotes from other official published sources. As these valuations are based on observable inputs in the current marketplace, they are classified as Level 2. Equity Securities — Equity securities consist of mutual funds and exchange-traded equity securities. The Company invests in these mutual funds for CRA purposes. The Company uses net asset value (“NAV”) information to determine the fair value of these equity securities. When NAV is available periodically and the equity securities can be redeemed at the publicly available NAV, the fair value of the equity securities is classified as Level 1. When NAV is available periodically, but the equity securities may not be readily marketable at its periodic NAV in the secondary market, the fair value of these equity securities is classified as Level 2. Exchange-traded equity securities are measured based on quoted prices on an active exchange market and classified as Level 1. Interest Rate Contracts — Interest rate contracts consist of interest rate swaps and options. The fair value of the interest rate swaps is determined using the market standard methodology of netting the discounted future fixed cash payments (or receipts) and the discounted expected variable cash receipts (or payments). The fair value of the interest rate options, which consist of floors and caps, is determined using the market standard methodology of discounting the future expected cash receipts that will occur if variable interest rates fall below (rise above) the strike rate of the floors (caps). In addition, to comply with the provisions of ASC 820, Fair Value Measurement, the Company incorporates credit valuation adjustments to appropriately reflect both its own and the respective counterparty’s nonperformance risk in the fair value measurements of its derivatives. The credit valuation adjustments associated with the Company’s derivatives utilize model-derived credit spreads, which are Level 3 inputs. Considering the observable nature of all other significant inputs utilized, the Company classifies these derivative instruments as Level 2. Foreign Exchange Contracts — The fair value of foreign exchange contracts is determined at each reporting period based on changes in the applicable foreign exchange rates. These are over-the-counter contracts where quoted market prices are not readily available. Valuation is measured using conventional valuation methodologies with observable market data. Due to the short-term nature of the majority of these contracts, the counterparties’ credit risks are considered nominal and result in no adjustments to the valuation of the foreign exchange contracts. Due to the observable nature of the inputs used in deriving the fair value of these contracts, the valuation of foreign exchange contracts is classified as Level 2. In addition, the Bank managed its foreign currency exposure in the net investment in its China subsidiary, East West Bank (China) Limited, a non-U.S. dollar (“USD”) functional currency subsidiary, with foreign currency non-deliverable forward contracts. These foreign currency non-deliverable forward contracts were designated as net investment hedges. The fair value of foreign currency non-deliverable forward contracts is determined by comparing the contracted foreign exchange rate to the current market foreign exchange rate. Key inputs of the current market exchange rate include the spot and forward rates of the contractual currencies. Foreign exchange forward curves are used to determine which forward rate pertains to a specific maturity. Due to the observable nature of the inputs used in deriving the estimated fair value, these instruments are classified as Level 2. Credit Contracts — Credit contracts utilized by the Company are comprised of credit risk participation agreements (“RPAs”) between the Company and institutional counterparties. The fair value of the RPAs is calculated by determining the total expected asset or liability exposure of the derivatives to the borrowers and applying the borrowers’ credit spread to that exposure. Total expected exposure incorporates both the current and potential future exposure of the derivatives, derived from using observable inputs, such as yield curves and volatilities. Due to the observable nature of all other significant inputs used in deriving the estimated fair value, credit contracts are classified as Level 2. Equity Contracts — Equity contracts consist of warrants to purchase private company common or preferred stock, and any liability-classified contingently issuable shares of the Company. The fair value of the warrants is based on the Black-Scholes option pricing model. The model uses inputs such as the offering price observed in the most recent round of funding, stated strike price, warrant expiration date, risk-free interest rate based on duration-matched U.S. Treasury rate and equity volatility. The Company applies proxy volatilities based on the industry sectors of the private companies. The model values are then adjusted for a general lack of liquidity due to the private nature of the underlying companies. Since both equity volatility and liquidity discount assumptions are subject to management’s judgment, measurement uncertainty is inherent in the valuation of private company warrants. Due to the unobservable nature of the equity volatility and liquidity discount assumptions used in deriving the estimated fair value, warrants from private companies are classified as Level 3. On a quarterly basis, the changes in the fair value of warrants from private companies are reviewed for reasonableness, and a measurement of uncertainty analysis on the equity volatility and liquidity discount assumptions is performed. In connection with the Company’s acquisition of a 49.99% equity interest in an investee during the third quarter of 2023, the Company granted 349 thousand performance-based restricted stock units (“RSUs”) as part of its consideration, in addition to $95 million in cash. The vesting of these equity contracts on September 1, 2028, is contingent on the investee meeting certain financial performance targets during the performance period. The fair value of liability-classified equity contracts varies based on the operating revenue and operating EBITDA of the investee to be achieved during the future performance period. These performance-based RSUs are expected to vest into a variable number of the Company’s common stock, ranging from 20% to 200% of the target performance-based RSUs granted. Due to the unobservable nature of the input assumptions, these equity contracts are classified as Level 3. For additional information on the equity contracts, refer to Note 5 — Derivatives to the Consolidated Financial Statements in this Form 10-Q. Commodity Contracts — Commodity contracts consist of swaps and options referencing commodity products. The fair value of the commodity option contracts is determined using the Black-Scholes model and assumptions that include expectations of future commodity price and volatility. The future commodity contract price is derived from observable inputs such as the market price of the commodity. Commodity swaps are structured as an exchange of fixed cash flows for floating cash flows. The fair value of the commodity swaps is determined using the market standard methodology of netting the discounted future fixed cash payments (or receipts) and the discounted expected variable cash receipts (or payments) based on the market prices of the commodity. The fixed cash flows are predetermined based on the known volumes and fixed price as specified in the swap agreement. The floating cash flows are correlated with the change of forward commodity prices, which is derived from market corroborated futures settlement prices. As a result, the Company classifies these derivative instruments as Level 2 due to the observable nature of the significant inputs utilized. The following tables present financial assets and liabilities that are measured at fair value on a recurring basis as of September 30, 2025 and December 31, 2024:

(2)Equity contracts classified as derivative liabilities consist of performance-based RSUs granted as part of EWBC’s consideration in an investment. Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis Assets measured at fair value on a nonrecurring basis may include certain individually evaluated loans held-for-investment, loans held-for-sale, affordable housing partnership, tax credit and CRA investments, OREO, and other nonperforming assets. Nonrecurring fair value adjustments may result from the impairment on certain individually evaluated loans held-for-investment and affordable housing partnership, tax credit and CRA investments, from the write-downs of OREO and other nonperforming assets, or from the application of lower of cost or fair value on loans held-for-sale. Individually Evaluated Loans Held-for-Investment — Individually evaluated loans held-for-investment are classified as Level 3 assets. The following two methods are used to derive the fair value of individually evaluated loans held-for-investment: •Discounted cash flow valuation techniques consist of developing an expected stream of cash flows over the life of the loans, and then calculating the present value of the loans by discounting the expected cash flows at a designated discount rate. •When the repayment of an individually evaluated loan is dependent on the sale of the collateral, the fair value of the loan is determined based on the fair value of the underlying collateral, which may take the form of real estate, inventory, equipment, contracts or guarantees. The fair value of the underlying collateral is generally based on third-party appraisals, or an internal valuation if a third-party appraisal is not required by regulations or is unavailable. An internal valuation utilizes one or more valuation techniques such as the income, market and/or cost approaches. Affordable Housing Partnership, Tax Credit and CRA Investments, Net — The Company conducts due diligence and secures applicable internal and external approval on its affordable housing partnership, tax credit and CRA investments prior to closing the investment and initial funding. After closing, the Company continues its periodic monitoring process to ensure that book values are realizable, the investments are performing as expected and there is no significant tax credit recapture risk. This monitoring process includes reviewing the investment entity’s financial statements, production reports and annual tax returns, the annual financial statements of the sponsor and guarantor (if any) and a comparison of the actual performance to plan based on the final financial model at the time of closing. The Company assesses its tax credit and other investments for possible other-than-temporary impairment on an annual basis or when events or circumstances suggest that the carrying amount of the investments may not be realizable. These circumstances can include, but are not limited to the following factors: •expected future cash flows that are less than the carrying amoun t of the investment; •changes in the economic, market or technological environment that could adversely affect the investee’s operations; •the potential for tax credit recapture; and •other factors that raise doubt about the investee’s ability to continue as a going concern, such as negative cash flows from operations and the continuing prospects of the underlying operations of the investment. All available information is considered in assessing whether a decline in value is other-than-temporary. Generally, none of the aforementioned factors are individually conclusive and the relative importance placed on individual facts may vary depending on the situation. In accordance with ASC 323-10-35-32, Investments — Equity Method and Joint Ventures, an impairment charge would only be recognized in earnings for a decline in value that is determined to be other-than-temporary. Other Real Estate Owned — The Company’s OREO represents properties acquired through foreclosure, or through full or partial satisfaction of loans held-for-investment such as an acceptance of a deed-in-lieu of foreclosure. These OREO properties are recorded at estimated fair value less the costs to sell at the time of foreclosure or at the lower of cost or estimated fair value less the costs to sell subsequent to acquisition. On a monthly basis, the current fair market value of each OREO property is reviewed to ensure that the current carrying value is appropriate. OREO properties are classified as Level 3. The following tables present the carrying amounts of assets that were still held and had fair value adjustments measured on a nonrecurring basis as of September 30, 2025 and December 31, 2024:
