Repurchase Agreements, and Securities Lending Transactions Accounted for as Secured Borrowings REPURCHASE AGREEMENTS AND SECURITIES LENDING TRANSACTIONS ACCOUNTED FOR AS SECURED BORROWINGS
The following tables present gross obligations for payables under repurchase agreements, payables under securities lending transactions and obligations to return securities received as collateral by remaining contractual maturity and class of collateral pledged at March 31, 2025 and 2026. Potential risks associated with these arrangements primarily relate to market and liquidity risks. To manage risks associated with market exposure, the MUFG Group generally revalues the collateral underlying its repurchase agreements and securities lending transactions on a daily basis and monitors the value of the underlying securities, consisting of primarily high-quality securities such as Japanese national government and Japanese government agency bonds, and foreign government and official institution bonds. In the event the market value of such securities falls below the related agreements at contract amounts plus accrued interest, the MUFG Group may be required to deposit additional collateral when appropriate. To address liquidity risks, the MUFG Group conducts stress tests to ensure the adequate level of liquidity is maintained in the event of a decline in the fair value of any collateral pledged.
