At 31 December 2025 the exposure to credit risk of the derivatives presented in the balance sheet is not significant because they are subject to netting and collateral agreements (see note 51.d).
Loans and advances to credit institutions and Loans and advances includes reverse repos amounting to EUR 71,129 million at 31 December 2025.

At 31 December 2025, the amount of the change in the fair value of financial liabilities at fair value through profit or loss attributable to changes in their credit risk during the year is not material.
In relation to liabilities designated at fair value through profit or loss where it has been determined at initial recognition that the credit risk is recorded in accumulated 'Other comprehensive income' (see 'Statement of recognised income and expense') the amount that the Group would be contractually obliged to pay on maturity of these liabilities at 31 December 2025 is EUR 1,281 million higher than their carrying amount (EUR 1,851 million higher at 31 December 2024 and EUR 866 million higher at 31 December 2023, no significant impact on results as its fair value is covered by hedging operations.
Within Deposits, there are repurchase agreements amounting to EUR 75,562 million at 31 December 2025.
