MEXC Opens Compliance Review After FinCEN’s U.S. Order

By Marcus Bennett

FinCEN alleges MEXC processed at least $16 billion in transactions connected to sanctions evasion, cybercrime and other illegal activity between May 2021 and May 2026. The order from the U.S. Treasury’s Financial Crimes Enforcement Network bars U.S. financial institutions from processing transfers involving the exchange.

On Nov. 7, MEXC CEO Vugar Usi said the company had opened an independent review of its anti-money laundering and sanctions controls. Usi said MEXC was “seeking constructive engagement with U.S. authorities,” and would keep issuing updates as the review proceeds.

Deposits and withdrawals were operating normally, Usi said, although withdrawals had increased. He described the activity as orderly and said customer assets were safe. MEXC’s statement puts the immediate operating picture in contrast with the reach of FinCEN’s order.

What FinCEN alleges

FinCEN’s allegation spans five years, from May 2021 through May 2026, and involves entities tied to Iran, North Korea and Russia in transactions the agency says MEXC processed. The agency grouped sanctions evasion, cybercrime and other illegal activity under the same enforcement action.

The order reaches the exchange through the U.S. financial system. It bars financial institutions from processing transfers involving MEXC. MEXC described the measure as a restriction on its access to the U.S. financial system.

That distinction sets the enforcement mechanism. U.S. institutions must stop processing covered transfers. At the same time, MEXC still describes deposit and withdrawal activity as normal, subject to those transfer restrictions.

MEXC puts controls under review

Usi said MEXC “respects each user’s decision to withdraw funds.” The independent review covers the exchange’s anti-money laundering and sanctions compliance controls. His Nov. 7 update also promised further updates as the review proceeds.

The company’s response combines continued withdrawals with a review of its controls, leaving customers and counterparties to follow the process through promised updates while the review continues. Increased withdrawals are the visible operational change, while Usi characterized the flow as orderly. His commitment to keep issuing updates gives customers and counterparties a way to track operational changes without relying on speculation.

What does the order change for customers?

The practical change concerns transfer access, not MEXC’s stated ability to process withdrawals. U.S. financial institutions can no longer process transfers involving the exchange under the order. MEXC says deposits and withdrawals remain operational and says customer assets are safe.

Customers who depend on U.S.-linked payment intermediaries may therefore encounter constraints on particular transfer routes. The announcement does not identify specific payment methods, so the order’s everyday effect will depend on which institutions and transfer channels are involved in a customer’s transaction.

Usi’s assurance about assets and the order about processing address separate questions. One concerns asset safety and withdrawal availability. The other concerns who may move funds through the U.S. financial system. MEXC can keep withdrawals open while still facing a limit on its U.S. transfer connectivity.

For users, an open exchange no longer captures the full access picture. The decisive operational test is whether the chosen withdrawal path relies on a U.S. financial institution covered by FinCEN’s order.

The next checkpoint

The next checkpoint is MEXC’s promised update on the independent review, while further operational guidance from U.S. authorities could reshape affected transfer routes. Until then, the availability of U.S.-linked transfer channels is the market-structure variable to watch.
