OFAC stated in the announcement that foreign financial institutions continuing transactions with sanctioned Iranian financial institutions could be subject to sanctions at any time without prior notice.
Foreign financial institutions that assist Iran in accessing the global financial system, including by providing financial services to Iranian banks and their subsidiaries or branches in third countries, may also face sanctions.
If Iran-related transactions cause U.S. financial institutions or other U.S. persons to violate sanctions regulations, foreign financial institutions could also face civil or criminal enforcement penalties. (yc)
