Swiss Bank MBaer Liquidated Following U.S. Accusations of Facilitating Illicit Finance
Zurich-based MBaer Merchant Bank AG has been ordered into liquidation by Swiss regulators, just days after the U.S. Treasury Department accused the institution of funneling over $100 million through the American financial system on behalf of actors linked to Russia, and Iran. The move marks a significant escalation in international efforts to clamp down on financial networks supporting illicit activities, and highlights the increasing scrutiny faced by Swiss banks regarding their compliance with sanctions and anti-money laundering regulations. The Swiss Financial Market Supervisory Authority (Finma) confirmed the liquidation order on Friday, February 26, 2026, following MBaer’s decision to drop its appeal against the regulator’s earlier decision to revoke its banking license.
The U.S. Treasury’s Financial Crimes Enforcement Network (FinCEN) proposed a rule on February 26, 2026, that, if finalized, would sever MBaer’s access to the U.S. Financial system. This action stems from allegations that MBaer actively supported individuals and entities involved in money laundering and terrorist financing, including those connected to Iran’s Islamic Revolutionary Guard Corps and its Quds Force. According to Secretary of the Treasury Scott Bessent, “Banks should be on notice that the U.S. Treasury will aggressively protect the integrity of the U.S. Financial system using the full force of our authorities.” The proposed rule would prohibit U.S. Financial institutions from opening or maintaining correspondent accounts for, or on behalf of, MBaer.
Finma’s investigation, initiated in 2024, revealed that MBaer lacked adequate structures to combat money laundering, enabling clients to circumvent international asset freezes. The regulator stated that approximately 98% of the bank’s assets – totaling $6.4 billion at the end of 2025 – originated from high-risk clients. This concentration of high-risk assets, coupled with evidence suggesting active assistance in circumventing sanctions, prompted Finma to accept decisive action. The regulator emphasized that during the appeal process, MBaer was prohibited from making public statements regarding the measures taken against it.
U.S. Treasury Details Allegations Against MBaer
The U.S. Treasury’s accusations against MBaer are detailed in a press release issued by FinCEN. The release alleges that MBaer has been a “critical access node to the U.S. Dollar for a wide variety of illicit actors, putting U.S. National security at risk and undermining the integrity of the U.S. Financial system.” The proposed rule invokes Section 311 of the USA PATRIOT Act, which allows FinCEN to impose special measures on foreign financial institutions deemed to be of primary money laundering concern.
The Treasury Department’s concerns extend beyond simply facilitating transactions; they allege that MBaer actively enabled corruption linked to Russian money laundering and actively aided in terrorist financing on behalf of Iran-aligned groups. This suggests a deliberate effort to circumvent international sanctions and support activities deemed detrimental to U.S. Interests. The scale of the alleged illicit financial flows – exceeding $100 million – underscores the seriousness of the accusations.
MBaer’s Origins and Connection to Julius Baer
MBaer Merchant Bank AG was established in 2018 by Michael Baer, a great-grandson of Julius Baer, the founder of the well-known Zurich-based private banking group, Julius Baer. However, it’s crucial to note that MBaer is a separate entity and has no direct affiliation with the larger Julius Baer institution, as clarified by the U.S. Treasury. The Associated Press reported that officials were keen to emphasize this distinction to avoid reputational damage to the larger bank.
Despite its relatively recent establishment, MBaer quickly amassed a significant asset base, reaching approximately $245 million by 2020, making it the 200th largest bank in Switzerland. However, the concentration of its assets in high-risk clients, as highlighted by Finma, raises questions about the bank’s due diligence procedures and risk management practices. The rapid growth, combined with the alleged involvement in illicit finance, has drawn intense scrutiny from both Swiss and U.S. Authorities.
Implications for Swiss Banking and International Sanctions Enforcement
The liquidation of MBaer and the U.S. Treasury’s actions send a strong signal to the Swiss banking sector regarding the importance of robust compliance with international sanctions and anti-money laundering regulations. Switzerland has long been under pressure to increase transparency and crack down on illicit financial flows, and this case demonstrates a willingness to take decisive action against institutions that fail to meet these standards. The incident also underscores the challenges of enforcing sanctions in a globalized financial system, where illicit actors constantly seek modern avenues to evade detection.
Experts suggest that the MBaer case could lead to increased scrutiny of other Swiss banks with similar risk profiles. The focus will likely be on strengthening due diligence procedures, enhancing transaction monitoring systems, and improving cooperation with international law enforcement agencies. The incident also highlights the potential for smaller, less regulated financial institutions to be exploited by illicit actors, emphasizing the need for comprehensive oversight across the entire banking sector.
What Happens Next?
The immediate next step is the liquidation of MBaer’s assets, overseen by appointed liquidators. Finma has not yet provided a detailed timeline for this process, but it is expected to be complex given the bank’s international connections and the nature of its client base. The U.S. Treasury’s proposed rule regarding MBaer’s access to the U.S. Financial system is currently subject to a public comment period, after which it will be finalized. Further investigations may also be launched to identify and prosecute individuals and entities involved in the alleged illicit financial activities facilitated by MBaer. The outcome of these investigations could have broader implications for the fight against money laundering and terrorist financing.
This case serves as a stark reminder of the ongoing efforts to combat illicit finance and the critical role played by both national regulators and international cooperation. The swift action taken by both Swiss and U.S. Authorities demonstrates a commitment to protecting the integrity of the global financial system and preventing the flow of funds to those who seek to undermine international security.
