Should foreign banks prioritize US sanctions compliance over business dealings in Iran?
The US Office of Foreign Assets Control released a new sanctions alert warning international banks against supporting Iranian financial sectors. Institutions that knowingly facilitate access to the global financial system now face potential loss of access to US correspondent accounts.
Why it matters
This move reinforces the aggressive application of secondary sanctions intended to isolate Iran from global liquidity. By restricting US account access, the government aims to force foreign banks to choose between Iranian operations and the US financial system.
The agency released FAQ 156 regarding restrictions on US correspondent accounts and expanded sanctions risk under Executive Order 13902. Enforcement measures now specifically target entities identified for facilitating Iranian financial access.

Market Landscape
This enforcement action signals a broader push to tighten global compliance standards by utilizing the US dollar as a primary leverage point. It forces international banks to reconsider their risk exposure to sanctioned jurisdictions to maintain their vital links to the US market.
Average customers of these foreign banks may face significant delays or outright termination of international wire transfers in US dollars. Companies with existing business ties to these specific institutions should review their banking partners to avoid potential fund freezing.
The takeaway
Banks operating internationally must conduct enhanced due diligence to ensure they do not inadvertently facilitate transactions with prohibited Iranian entities. Failure to comply with US guidance poses an existential threat to an institution's ability to operate within the global dollar economy.
