REGAS Commentary

This decision taken by the BDDK will directly affect all persons and entities that have commercial relations with Bank Mellat’s Istanbul branch or hold deposits with that branch. The revocation of the operating licence will cause the bank’s assets and liabilities to enter into a liquidation process, which will significantly alter depositors’ access to their funds and the fate of other financial transactions. This situation constitutes a precedent that also underscores the critical importance of regulatory compliance for other foreign banks operating in Türkiye.
