MBaer bank faces a major test after the U.S. Financial Crimes Enforcement Network (FinCEN) announced a proposal on February 27 to bar the Zurich lender from U.S. correspondent banking. The FinCEN proposal flags alleged illicit flows and raises a money laundering risk warning. If finalized, MBaer bank could lose USD clearing access, disrupting dollar payments for Swiss clients. Swiss regulator FINMA has installed a monitor while the bank appeals. We outline what this means for Swiss customers, counterparties, and compliance planning across CH.

What FinCEN’s move means

FinCEN can impose a special measure that prohibits U.S. banks from keeping correspondent or payable-through accounts for a foreign bank. For MBaer bank, this would sever standard USD clearing routes. Swiss firms and wealth clients who send or receive dollars through the bank would likely face delays or rerouting. The move is not yet final, but it signals high sanctions and money laundering risk to global banks.

U.S. authorities allege MBaer bank processed hundreds of millions for high-risk customers tied to Iran, Russia, and Venezuela, according to Reuters. In Switzerland, FINMA has appointed a monitor as the bank appeals, framing the case as a money laundering risk to the system, per Swissinfo. The allegations are contested, but the regulatory stance is strict.

What it means for Swiss clients and partners

Even before any final rule, banks may de-risk. Swiss counterparties could reassess exposures, request enhanced due diligence, or restrict new USD business. Asset managers and fiduciaries may face more questions from their own U.S. correspondents. The FinCEN proposal heightens reputational pressure and formalizes a money laundering risk label that can influence onboarding, trade finance lines, and custody arrangements across Switzerland.

Many Swiss exporters invoice in USD even though they report in CHF. If MBaer bank loses U.S. access, clients might need alternative routes via third-party correspondents or shift to EUR. That could add costs, wider spreads, and slower settlement. Corporate treasurers should test payment rails, review FX hedges tied to USD legs, and confirm trade finance availability around shipment and insurance documents.

How MBaer bank and clients can respond

MBaer bank can preserve continuity by prioritizing CHF and EUR channels, communicating cut-off times, and publishing sanctions-control enhancements. The bank may seek non-U.S. correspondents for limited services that remain lawful. Close cooperation with FINMA and the appointed monitor will be key. Clear client letters, dedicated hotlines, and updated risk disclosures can stabilize flows while the review proceeds.

Clients should map all USD touchpoints with their bank, from payroll and suppliers to custody, margin, and remittances. Consider backup accounts for dollar flows, keep KYC documents ready, and request written service assurances. Investors should ask for transaction screening metrics, sanctions hits handling, and audit trails. Document contingency steps so auditors can see prudent Swiss bank compliance in place.

Broader Swiss bank compliance lessons

Swiss bank compliance programs should review customer risk scoring, sanctions screening coverage, and payment filtering rules for nested and pass-through activity. Special focus is needed for higher-risk geographies, PEPs, and trade finance red flags. Boards should set clear escalation thresholds and testing plans. Independent audits and data quality checks help prove controls work for both CHF and cross-border USD traffic.

Watch for any FinCEN final rule, public remediation plans from MBaer bank, and further steps by FINMA. Counterparties may publish their own risk notices. Clients should monitor service status for USD wires, credit lines, and custody settlements. If the proposal advances, broader banks may strengthen sanctions screening and file more SARs, affecting timelines for onboarding and cross-border payments across Switzerland.

Final Thoughts

FinCEN’s proposed action against MBaer bank is a clear warning for sanctions and AML standards in Switzerland. While not yet final, it can disrupt USD access and raise costs for clients. The priority now is resilience: confirm alternate payment routes, update KYC packs, and keep close contact with relationship managers. Corporate treasurers should rehearse fallback processes, stress-test USD-linked hedges, and refresh trade finance documentation to avoid shipment delays.

Wealth clients should seek clear statements on custody, margin finance, and corporate actions that rely on U.S. market plumbing. For the wider sector, the episode underscores that Swiss bank compliance must be well-documented, tested, and transparent. Proactive communication reduces friction. Thoughtful planning today can keep payments moving and protect business continuity while regulators decide the outcome.
