Treasury severs crypto exchange MEXC Global from US financial system and sanctions eight Canadian money services firms in Iran sanctions sweep

The U.S. Treasury's Operation Economic Outcast moved against Iran-linked financial channels on two fronts Friday, cutting a top-20 global crypto exchange off from the U.S. bank system and designating eight Canada-based money services businesses for operating inside the digital asset sector of the Iranian economy.

The FinCEN action is the first of its kind against an exchange of MEXC Global's size. The agency cited the Combating Russian Money Laundering Act, using its Section 9714 authority to add the exchange to the Financial Crimes Enforcement Network's list of primary money laundering concerns, a step that compels U.S. banks and money transmitters to stop processing transactions for the named firm.

What the order does

Per FinCEN's news release of Nov 6, the order finds that MEXC Global, which it describes as a top-20 crypto asset exchanger worldwide with roughly $1 billion in daily transaction volume and about $5 billion in reserves as of September 2026, funneled at least $16 billion in illicit value movement between May 2021 and May 2026. The breakdown, attributed by Treasury and Reuters to the same day, includes nearly $1.5 billion linked to Russian sanctions evasion, of which $232 million came in direct dealings with U.S., EU and UK-sanctioned entities, and about $1 billion in direct transactions with more than 40 Iranian crypto exchangers.

The agency said MEXC Global was still processing business with sanctioned Russian exchange Garantex and its successor Grinex as recently as June 2026, and that it facilitated about $22 million for the OFAC and EU-sanctioned Central Bank of Iran and the Islamic Revolutionary Guard Corps Qods Force. The order takes effect 30 days after publication in the Federal Register, which sets the near-term clock for the exchange's U.S.-dollar funding channels, stablecoin and fiat on-ramps, and any U.S.-nexus counterparties that clear for it.

Designations of eight Canadian firms

In the same package, Treasury's Office of Foreign Assets Control designated eight Canada-based money services businesses under Executive Order 13902 for operating in the digital asset sector of the Iranian economy: Million Exchange, 1380079 BC Limited, Top PC Technician Inc, NIA Nations, Farah Exchange, CCC Inc, B Galaxy Inc and Darvish Exchange. OFAC's listing places the firms on the Specially Designated Nationals list, freezing any U.S.-dollar assets and barring U.S. persons from dealing with them, which affects remittance and digital-asset corridors that run through Canada.

Treasury's press release of Nov 6 drew a direct line from these businesses to sanctioned Canadian drug trafficker Ryan Wedding, describing the designations as disrupting money movement that funnels through digital assets and remittance channels tied to Iranian shadow finance.

What it prices

The priced consequence runs through the crypto sector's plumbing before it reaches any single token. An exchange the size of MEXC Global losing U.S. bank clearance shifts the funding and liquidity picture for every U.S.-facing stablecoin and fiat on-ramp it relied on, and it gives the market a concrete template for how a venue-level Section 9714 order operates, one that institutional counterparties and U.S.-listed crypto-tied equities will have to price against any similar exposure. For the dollar basis and stablecoin flows, the open question is how quickly liquidity reallocates to venues with clean U.S. access.

The action is also another escalation in the U.S.-Iran financial war, following the Qeshm strike and the Hormuz campaign already covered this week. It runs in parallel with the wider Operation Economic Outcast sweep Washington is running during the military escalation, including action against the Russian sanctions-evasion network A7 and Iranian shadow-finance facilitators. Treasury Secretary Scott Bessent was quoted on the record Friday: "Either you support the Iranian regime, or you have access to the U.S. financial system."

The next dated catalyst is Federal Register publication of the FinCEN order, from which the 30-day effectiveness clock runs. Operators and counterparties will also watch for follow-on OFAC or FinCEN actions against other venues under Operation Economic Outcast, and for how MEXC Global's U.S.-connected funding and liquidity channels respond over the next month.
