Turkiye’s banking watchdog has revoked the operating licence of Iranian lender Bank Mellat’s branch in the Turkish city of Istanbul.

The regulator said the decision was taken under a clause of Turkiye’s banking law allowing a bank’s licence to be revoked or withdrawn if its continued operation is deemed to pose a risk to depositors’ rights or to the security and stability of the financial system.

Bank Mellat has been subject to Western sanctions for years over accusations that Tehran was pursuing a nuclear weapon under the cover of a civil nuclear programme.

Those sanctions were lifted as part of a landmark 2015 deal between Tehran and world powers to curb Iran’s nuclear ambitions. However, the United States unilaterally pulled out of the agreement in May 2018, reimposing economic sanctions on the country.
