Treasury cuts crypto exchange MEXC off from U.S. banks and sanctions 8 Canadian firms over Iran

The U.S. Treasury took two linked actions against Iran's use of crypto on Friday, both under what it calls Operation Economic Outcast. The Financial Crimes Enforcement Network (FinCEN) issued an order cutting MEXC Global off from the U.S. financial system, and the Office of Foreign Assets Control (OFAC) designated eight Canadian money services businesses that Treasury says help move money into and out of Iran.

What FinCEN says about MEXC

Treasury describes MEXC Global as a convertible virtual currency exchanger founded in 2018 that, as of September 2026, processed more than $1 billion a day and held about $5 billion in reserves. Treasury calls it one of the 20 largest in the world. These are Treasury's figures; we have not verified them independently.

The department's allegations, all from its release:

• At least $16 billion in funds tied to sanctions evasion, cybercrime and other illicit activity between May 2021 and May 2026.
• Nearly $1.5 billion linked to Russian sanctions evasion, including $232 million in direct transactions with U.S., EU and UK-sanctioned entities.
• About $1 billion in direct transactions with more than 40 identified Iranian exchanges, and about $22 million for Iran's central bank and the Islamic Revolutionary Guard Corps and its Qods Force.
• Processing for Garantex, a sanctioned Russian exchange, and its successor Grinex as recently as June 2026.

The order bars U.S. financial institutions from transmitting funds to or from MEXC Global. It takes effect 30 days after publication in the Federal Register, so banks and payment firms have a window to cut ties. It does not touch existing Bank Secrecy Act duties or OFAC sanctions. We did not find a response from MEXC in the sources we read.

The Canadian firms

OFAC named Million Exchange (Diverse Trade Inc), 1380079 BC Limited and Top PC Technician Inc (both linked to Amin Exchange), NIA Nations Currency, Farah Exchange (2397639 Ontario Ltd), CCC Inc, B Galaxy Inc (Cryptoyal) and Darvish Exchange. Treasury says they swap Iranian rials and other currencies for digital assets, and that several transacted with sanctioned Iranian exchanges such as Nobitex, Wallex and Aban Tether, or with addresses linked to the IRGC. Treasury also says several worked with Ryan Wedding, a Canadian drug trafficker OFAC already sanctioned, who was taken into U.S. custody in January.

The designations rest on Executive Order 13902, the Iranian digital asset sector authority. Anything owned 50% or more by a blocked party is also blocked, and U.S. persons generally cannot deal with them. The action was coordinated with FinCEN, Canada's FINTRAC and the DEA. It follows OFAC's June 2 designations of four Iranian exchanges and August 7 designations of Aban Tether and Shelbit.

Who it actually hits

For a U.S. business, the practical risk is indirect. A payments firm, bank or crypto platform that has any exposure to MEXC now has about a month to wind it down. Any company that pays Canadian vendors through a money services business should confirm the vendor is not among the eight, because a blocked name makes the payment a sanctions problem for the sender too, and OFAC can penalize on a strict liability basis.

What it means for oil, shipping, airlines, defense and consumers

This is a financial-pressure move, not a military one, and the market treated it that way. Treasury's tools tighten Iran's ability to get paid while the larger question, whether talks or strikes come next, stays open. Friday's closes, from Yahoo Finance, put December WTI at $90.34, down 6.3% from Monday's $96.46 close, and front-month Brent at $97.76, down 6.7% from $104.77. Gold ended at $4,079.50. We have no evidence these sanctions moved any of them.

Shipping and insurance: nothing in these releases changes Gulf war-risk cover; the sanctions affect payments, not transit. Airlines: the JETS ETF closed at $28.72, up 2.4% on the week from $28.05. Defense: the ITA ETF closed at $68.98, down 3.6% from $71.56 on Monday. Consumers: there is no direct pump-price effect from a banking order; fuel costs still follow crude. Crypto: Bitcoin traded near $75,800 on Coinbase, about 0.6% below its 24-hour open, so the news did not register as a market-wide shock.

Watch for the Federal Register notice that starts the 30-day clock, any MEXC statement, and whether OFAC follows with more exchange designations.
