U.S. Sanctions Eight Canadian Firms, Restricts MEXC Transfers

U.S. Treasury’s Office of Foreign Assets Control (OFAC) designated eight Canadian money services businesses over alleged Iran-linked digital-asset transfers. The Financial Crimes Enforcement Network (FinCEN), a bureau within Treasury, issued a separate order that would restrict certain U.S. financial transfers involving MEXC Global.

Both actions were announced under Treasury’s Operation Economic Outcast. FinCEN’s transfer restrictions would begin once 30 days had elapsed from publication in the Federal Register. The designation action and exchange order use separate mechanisms, though both involve digital-asset channels linked in the announcement to illicit finance and designated counterparties across borders.

MEXC Global accounts for the largest disclosed figure in the action. FinCEN’s order “estimates MEXC facilitated $16.7 billion in funds connected to Russian illicit finance and other illicit activity” from May 2021 through May 2026.

The order separately identifies:

• About $1.87 billion in transactions with Iran exposure.
• More than $1 billion in direct transactions with more than 40 identified Iranian crypto exchanges.
• About $22 million associated with Iran’s central bank, the Islamic Revolutionary Guard Corps (IRGC) and its Quds Force.

The figures do not describe one uniform pool of funds. The $16.7 billion estimate covers a five-year window and spans Russian illicit finance plus other illicit activity. The $1.87 billion entry is defined by Iran exposure.

The direct-exchange figure covers more than 40 identified Iranian crypto exchanges. The $22 million entry concerns Iran’s central bank, the IRGC and its Quds Force. That distinction prevents the headline total from being read as one Iran-linked figure. It also reflects the different risk categories in FinCEN’s order: broad illicit-finance exposure, direct dealings with identified exchanges, and institutional or force-related exposure.

Treasury said the firms “converted rials and other currencies into digital assets” for cross-border dealings tied to Iran. The department said many transacted with sanctioned Iranian crypto exchanges or addresses associated with the IRGC. Treasury also alleged that several firms handled drug proceeds for Ryan Wedding.

Treasury framed that conduct as alleged wrongdoing. Its account begins with the conversion of rials and other currencies into digital assets for Iran-linked cross-border dealings. It then points to sanctioned Iranian exchanges, IRGC-associated addresses and alleged drug proceeds for Ryan Wedding.

OFAC’s designations concern the eight Canadian money services businesses. FinCEN’s order concerns specified U.S. financial transfers involving MEXC Global. The two cases share Operation Economic Outcast, but they are not the same enforcement mechanism.

What changes for firms using the affected channels?

Businesses exposed to either action must distinguish a sanctions-designated counterparty from a transfer covered by the MEXC order, because the legal trigger and operational response are not the same. For the Canadian firms, the core issue is OFAC designation. For MEXC Global, it is whether a U.S. transfer falls within FinCEN’s restrictions.

Under the announced framework, the OFAC action attaches to the Canadian entities themselves. The FinCEN measure attaches to certain U.S. transfers involving MEXC Global. One check cannot substitute for the other. A firm that removes the eight Canadian counterparties would still need to assess any MEXC route within the transfer order.

The MEXC action is narrower than a blanket shutdown. It applies to certain U.S. financial transfers involving MEXC Global. Businesses exposed to the affected channels need to identify which relationships and payment routes fall within those restrictions before processing them.

Timing provides the only stated transition. The transfer restrictions would begin once 30 days had elapsed from publication in the Federal Register. The next fixed point is publication: 30 days later, the MEXC-related limits take effect, while the OFAC designations against the eight Canadian firms proceed on their own enforcement track.
