Fair Value of Assets and Liabilities [Abstract] |
Fair value of assets and liabilities | 19 Fair value of assets and liabilities Valuation methods The estimated fair values represent the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. It is a market-based measurement, which is based on assumptions that market participants would use and takes into account the characteristics of the asset or liability that market participants would take into account when pricing the asset or liability. Fair values of financial assets and liabilities are based on quoted prices in active market where available. When such quoted prices are not available, the fair value is determined by using valuation techniques. Valuation control framework The valuation control framework covers the product approval process (PARP), pricing, market data assessment and independent price verification (IPV), valuation adjustments, model use, fair value hierarchy and day one profit or loss. Valuation processes are governed by various governance bodies, including Local Parameter Committees, the Global Valuation and Impairment Committee, the Market Data Committee and the Valuation Model Committee. All relevant committees meet on a regular basis (monthly/quarterly), where the agenda covers the aforementioned valuation controls. The Global Valuation and Impairment Committee is responsible for the oversight and the approval of the outcome of impairments (other than loan loss provisions) and valuation processes. It oversees the quality and coherence of valuation methodologies and performance. The Valuation Model Committee is responsible for the approval of all valuation models used for the Fair valuation (IFRS) and Prudent Valuation (CRR) of positions measured at fair value. The Local Parameter Committee discusses the valuation results and monitors the performance of the valuation activities carried out on local or regional level. The Global Financial Markets Parameter Committee reviews the consolidated valuation outcome and resulting P&L for Financial Market products, targeting a globally consistent treatment across Financial Markets. The Banking Book Parameter Committee (BBPC) discusses the valuation topics for non-Financial Market and non-Group Treasury Wholesale Banking portfolios. The Market Data Committee is responsible for the approval of the market data used in valuation. Valuation adjustments Valuation adjustments are an integral part of the fair value. They are the adjustments to the output from a valuation technique in order to appropriately determine a fair value in accordance with IFRS13. ING considers various fair value adjustments including Bid-Offer adjustments, Model Risk adjustments, Bilateral Valuation Adjustments (BVA, consisting of Credit Valuation Adjustments or CVA, and Debit valuation Adjustments or DVA), Collateral Valuation Adjustment (CollVA) and Funding Valuation Adjustment (FVA). For financial instruments where the fair value at initial recognition is based on one or more significant unobservable inputs, a difference between the transaction price and the fair value resulting from the internal valuation process can occur. Such difference is referred to as Day One Profit or Day One Loss (hereafter: DOP). ING defers material DOP of instruments with significant unobservable valuation inputs, which are the financial instruments classified as Level 3 and financial instruments with material unobservable inputs into CVA which are not necessarily classified as Level 3. The DOP is amortised over the life of the instrument, or until the significant unobservable inputs become observable, or until the significant unobservable inputs become non-significant. The adjustments in fair value and the DOP reserve are disclosed in the below table. The following table presents the adjustments in fair value for financial assets and liabilities.

The following methods and assumptions were used by ING Group to estimate the fair value of the financial instruments: Equity securities Instrument description: Equity securities include stocks and shares, corporate investments and private equity investments. Valuation: If available, the fair values of publicly traded equity securities and private equity securities are based on quoted market prices. In the absence of active markets, fair values are estimated by analysing the investee’s financial position, result, risk profile, prospect, price, earnings comparisons and revenue multiples. Additionally, reference is made to valuations of peer entities where quoted prices in active markets are available. For equity securities, best market practice will be applied using the most relevant valuation method. All non-listed equity investments, including investments in private equity funds, are subject to a standard review framework which ensures that valuations reflect the fair values. Fair value hierarchy: The majority of equity securities are publicly traded, and quoted prices are readily and regularly available. Hence, these securities are classified as Level 1. Equity securities which are not traded in active markets mainly include corporate investments, fund investments and other equity securities and are classified as Level 3. Debt securities Instrument description: Debt securities include government bonds, financial institutions bonds and Asset-backed securities (ABS). Valuation: Where available, fair values for debt securities are generally based on quoted market prices. Quoted market prices are obtained from an exchange market, dealer, broker, industry group, pricing service, or regulatory service. The quoted prices from non-exchange sources are reviewed on their tradability of market prices. If quoted prices in an active market are not available, fair value is based on an analysis of available market inputs, which include consensus prices obtained from one or more pricing services. Furthermore, fair values are determined by valuation techniques discounting expected future cash flows using market interest rate curves, referenced credit spreads, maturity of the investment, and estimated prepayment rates where applicable. Fair value hierarchy: Government bonds and financial institution bonds are generally traded in active markets. Where quoted prices are readily and regularly available, they are classified as Level 1. The remaining positions are classified as Level 2 or Level 3 depending on the trading activity and observability of prices. Asset backed securities for which no active market is available and a wide discrepancy in quoted prices exists, are classified as Level 3. Derivatives Instrument description: Derivative contracts can either be exchange-traded or over the counter (OTC). Derivatives include interest rate derivatives, FX derivatives, credit derivatives, equity derivatives and commodity derivatives. Valuation: The fair value of exchange-traded derivatives is determined using quoted market prices in an active market and are classified as Level 1 of the fair value hierarchy. For instruments that are not actively traded, fair values are estimated based on valuation techniques. OTC derivatives and derivatives trading in an inactive market are valued using valuation techniques. The valuation techniques and inputs depend on the type of derivatives and the nature of the underlying instruments. The principal techniques used to value these instruments are based on, among others, discounted cash flows, option pricing models and Monte Carlo simulations. These valuation models calculate the present value of expected future cash flows, based on ‘no-arbitrage’ principles. The models are commonly used in the financial industry and inputs to the validation models are determined from observable market data where possible. Certain inputs may not be observable in the market, but can be determined from observable prices via valuation model calibration procedures. These inputs include prices available from exchanges, dealers, brokers or providers of pricing, yield curves, credit spreads, default rates, recovery rates, dividend rates, volatility of underlying interest rates, equity prices, and foreign currency exchange rates and reference is made to quoted prices, recently executed trades, independent market quotes and consensus data, where available. For uncollateralised OTC derivatives, ING applies Credit Valuation Adjustment to correctly reflect the counterparty credit risk in the valuation and Debit Valuation Adjustments to reflect the credit risk of ING for its counterparty. In addition, for these derivatives ING applies Funding Valuation Adjustment. Fair value hierarchy: The majority of the derivatives are priced using observable inputs and are classified as Level 2. Derivatives for which the input cannot be implied from observable market data are classified as Level 3. Loans and receivables Instrument description: Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. Loans and receivables carried at fair value include trading loans, being securities lending and similar agreement comparable to collateralised lending, syndicated loans, loans expected to be sold and receivables with regards to reverse repurchase transactions. Valuation: The fair value of loans and receivables is generally estimated by discounting expected future cash flows using a discount rate that reflects credit risk, liquidity, and other current market conditions. The fair value of mortgage loans is estimated by taking into account prepayment behaviour. Fair value hierarchy: Loans and receivables are predominantly classified as Level 2. Loans and receivables for which current market information about similar assets to use as observable, corroborated data for all significant inputs into a valuation model is not available, are classified as Level 3. Financial liabilities at fair value through profit and loss Instrument description: Financial liabilities at fair value through profit and loss include debt securities and debt instruments, primarily comprised of structured notes, which are held at fair value under the fair value option. Besides that, they include derivative contracts and repurchase agreements. Valuation: The fair values of securities in the trading portfolio and other liabilities at fair value through profit or loss are based on quoted market prices, where available. For those securities not actively traded, fair values are estimated based on internal discounted cash flow valuation techniques using interest rates and credit spreads that apply to similar instruments. Fair value hierarchy: The majority of the derivatives and debt instruments are classified as Level 2. Derivatives and debt instruments for which the input cannot be derived from observable market data are classified as Level 3. Transfers between Level 1 and 2 No significant transfers between Level 1 and Level 2 were recorded in the reporting period 2025. Level 3: Valuation techniques and inputs used Financial assets and liabilities in Level 3 include both assets and liabilities for which the fair value was determined using (i) valuation techniques that incorporate unobservable inputs as well as (ii) quoted prices which have been adjusted to reflect that the market was not actively trading at or around the balance sheet date. Unobservable inputs are inputs which are based on ING’s own assumptions about the factors that market participants would use in pricing an asset or liability, developed based on the best information available in the circumstances. Unobservable inputs may include volatility, correlation, spreads to discount rates, default rates and recovery rates, prepayment rates, and certain credit spreads. Valuation techniques that incorporate unobservable inputs are sensitive to the inputs used. Of the total amount of financial assets classified as Level 3 as at 30 June 2025 of EUR 11.6 billion (31 December 2024: EUR 11.0 billion), an amount of EUR 9.5 billion (81.9%) (31 December 2024: EUR 9.6 billion, being 87.2%) is based on unadjusted quoted prices in inactive markets. As ING does not generally adjust quoted prices using its own inputs, there is no significant sensitivity to ING’s own unobservable inputs. Furthermore, Level 3 financial assets include EUR 0.1 billion (31 December 2024: EUR 0.1 billion) which relates to financial assets that are part of structures that are designed to be fully neutral in terms of market risk. Such structures include various financial assets and liabilities for which the overall sensitivity to market risk is insignificant. Whereas the fair value of individual components of these structures may be determined using different techniques and the fair value of each of the components of these structures may be sensitive to unobservable inputs, the overall sensitivity is by design not significant. The remaining EUR 1.9 billion (31 December 2024: EUR 1.3 billion) of the fair value classified in Level 3 financial assets is established using valuation techniques that incorporate certain inputs that are unobservable. Of the total amount of financial liabilities classified as Level 3 as at 30 June 2025 of EUR 0.6 billion (31 December 2024: EUR 0.8 billion), an amount of EUR 0.5 billion (78.3%) (31 December 2024: EUR 0.6 billion, being 75.7%) is based on unadjusted quoted prices in inactive markets. As ING does not generally adjust quoted prices using its own inputs, there is no significant sensitivity to ING’s own unobservable inputs. Furthermore, Level 3 financial liabilities include EUR 0.1 billion (31 December 2024: EUR 0.1 billion) which relates to financial liabilities that are part of structures that are designed to be fully neutral in terms of market risk. As explained above, the fair value of each of the components of these structures may be sensitive to unobservable inputs, but the overall sensitivity is by design not significant. The remaining EUR 0.1 billion (31 December 2024: EUR 0.1 billion) of the fair value classified in Level 3 financial liabilities is established using valuation techniques that incorporates certain inputs that are unobservable. The table below provides a summary of the valuation techniques, key unobservable inputs and the lower and upper range of such unobservable inputs, by type of Level 3 asset/liability. The lower and upper range mentioned in the overview represent the lowest and highest variance of the respective valuation input as actually used in the valuation of the different financial instruments. Amounts and percentages stated are unweighted. The range can vary from period to period subject to market movements and change in Level 3 position. Lower and upper bounds reflect the variability of Level 3 positions and their underlying valuation inputs in the portfolio, but do not adequately reflect their level of valuation uncertainty. For valuation uncertainty assessment, reference is made to section Sensitivity analysis of unobservable inputs (Level 3).

1 Net gains/losses were recorded as ‘Valuation results and net trading income’ in the statement of profit or loss. The total amounts includes EUR 299 million (2024: EUR -41 million) of unrealised gains and losses recognised in the statement of profit or loss. 2 Revaluation recognised in other comprehensive income is included on the line ‘Net change in fair value of debt instruments at fair value through other comprehen sive income’. In 2025 and 2024, transfers out of Level 3 in trading assets primarily involved derivative instruments, as their valuations were no longer significantly impacted by unobservable inputs. In 2024, the transfer into Level 3 trading assets consisted of cross currency swap trades, which were transferred to Level 3 as a result of the valuation being significantly impacted by unobservable inputs. The transfer out of Level 3 in non-trading derivatives primarily involved derivative instruments, as their valuations were no longer significantly impacted by unobservable inputs. In 2025 and 2024, transfers into and out of Level 3 of financial assets mandatorily at fair value mainly relate to (long- term) reverse repurchase transactions for which the valuation being significantly impacted by unobservable inputs and no longer significantly impacted by unobservable inputs, respectively. In 2024, the transfer out of Level 3 of financial assets at FVOCI relates to Hold-to-Collect and Sell portfolio transferred to Level 2 resulting from change in methodology.

1 Net gains/losses were recorded as ‘Valuation results and net trading income’ in the statement of profit or loss. The total amount include s EUR -108 million (2024: EUR -206 million) of unrealised gains and losses recognised in the statement of profit or loss. In 2025, the transfers into Level 3 mainly consisted of trading liabilities attributed to cross currency swap trades transferred into Level 3 as a result of the valuation being significantly impacted by unobservable inputs. In 2024, the transfers into Level 3 mainly consisted of trading liabilities attributed to cross currency swap trades transferred into Level 3 as a result of the valuation being significantly impacted by unobservable inputs. The transfers out of Level 3 for non-trading derivatives are driven by interest rate swap trades, which were reclassified out of Level 3 as their valuations were no longer influenced by significantly unobservable inputs. Recognition of unrealised gains and losses in Level 3 Amounts recognised in the statement of profit or loss relating to unrealised gains and losses during the year that relate to Level 3 assets and liabilities are included in the line item ‘Valuation results and net trading income’ in the statement of profit or loss. Level 3: Sensitivity analysis of unobservable inputs Where the fair value of a financial instrument is determined using inputs which are unobservable and which have a more than insignificant impact on the fair value of the instrument, the actual value of those inputs at the balance date may be drawn from a range of reasonably possible alternatives. In line with market practice, the upper and lower bounds of the range of alternative input values reflect a level of valuation certainty. The actual levels chosen for the unobservable inputs in preparing the financial statements are consistent with the valuation methodology used for fair valued financial instruments. In practice, valuation uncertainty is measured and managed per exposure to individual valuation inputs (i.e. risk factors) at portfolio-level across different product categories. Where the disclosure looks at individual Level 3 inputs, the actual valuation adjustments may also reflect the benefits of portfolio offsets. This disclosure does not attempt to indicate or predict future fair value movement. The numbers in isolation give limited information as in most cases these Level 3 assets and liabilities should be seen in combination with other instruments (for example as a hedge) that are classified as Level 2. The valuation uncertainty in the table below is broken down by related risk class rather than by product. The possible impact of a change of unobservable inputs in the fair value of financial instruments where unobservable inputs are significant to the valuation is as follows:

1 In accordance with IFRS and for the purpose of this disclosure, the carrying amount of financial instruments with an immediate on demand feature is presented as fair value. The aggregation of the fair values presented above does not represent, and should not be construed as representing, the underlying value of ING Group. These fair values were calculated for disclosure purposes only. The carrying amount of financial instruments presented in the above table includes, when applicable, the fair value hedge adjustment, this explains why (for these cases) the carrying amount approximates fair value. Loans and advances to banks For short-term receivables from banks, carrying amounts represent a reasonable estimate of the fair value. The fair value of long-term receivables from banks is estimated by discounting expected future cash flows using a discount rate based on specific available market data, such as interest rates and appropriate spreads that reflects current credit risk or quoted bonds. Loans and advances to customers For short-term loans, carrying amounts represent a reasonable estimate of the fair value. The fair value of long-term loans is estimated by discounting expected future cash flows using a discount rate that reflects current credit risk, current interest rates, and other current market conditions where applicable. The fair value of mortgage loans is estimated by taking into account prepayment behaviour. Loans with similar characteristics are aggregated for calculation purposes. Securities at amortised cost Where available, fair values for debt securities are generally based on quoted market prices. Quoted market prices are obtained from an exchange market, dealer, broker, industry group, pricing service, or regulatory service. The quoted prices from non-exchange sources are reviewed on their tradability of market prices. If quoted prices in an active market are not available, fair value is based on an analysis of available market inputs, which include consensus prices obtained from one or more pricing services. Furthermore, fair values are determined by valuation techniques discounting expected future cash flows using market interest rate curves, referenced credit spreads, maturity of the investment, and estimated prepayment rates where applicable. Deposits from banks For short-term payables to banks carrying amounts represent a reasonable estimate of the fair value. The fair value of long-term payables to banks is estimated by discounting expected future cash flows using a discount rate based on available market interest rates and appropriate spreads that reflect ING’s own credit risk. Customer deposits In the current interest rate environment, there is significant embedded value in our on-demand deposits. However, for the purpose of this disclosure and in accordance with IFRS, the carrying amounts of deposits with an immediate on demand feature are presented as fair value. The fair value of deposits with fixed contractual terms has been estimated based on discounting future cash flows using the interest rates currently applicable to deposits of similar maturities. Debt securities in issue The fair value of debt securities in issue is generally based on quoted market prices, or if not available, on estimated prices by discounting expected future cash flows using a current market interest rate and credit spreads applicable to the yield, credit quality and maturity. Subordinated loans The fair value of publicly traded subordinated loans are based on quoted market prices when available. Where no quoted market prices are available, fair value of the subordinated loans is estimated using discounted cash flows based on interest rates and credit spreads that apply to similar instruments
