Will the United States impose formal financial sanctions on Switzerland’s MBaer Merchant Bank?

The U.S. Treasury has accused MBaer and its employees of facilitating money laundering linked to Venezuelan and Russian funds, as well as transactions benefiting Iran’s Islamic Revolutionary Guard Corps and its Quds Force. According to U.S. officials, more than $100 million allegedly moved through the U.S. financial system on behalf of sanctioned actors. This marks the first time U.S. authorities have publicly threatened a Swiss bank with measures under post-9/11 counterterrorism financial authorities. Switzerland’s regulator FINMA confirmed it is coordinating with U.S. authorities and has appointed an external auditor, while MBaer states it is fully cooperating and remains well-capitalized. The uncertainty lies in whether the case results in formal U.S. sanctions — such as SDN designation or correspondent banking restrictions — or whether enforcement stops short of full blocking measures.
