CoinEx to shut down after nine years, cites crypto slump and compliance costs

What happened

CoinEx, a cryptocurrency exchange operating for nearly nine years, announced on September 15, 2026 that it will fully shut down, according to The Crypto Times. The exchange cited a prolonged downturn in the crypto market, a contraction in industry trading volume and liquidity, rising regulatory requirements in major jurisdictions, and compliance costs it said had exceeded reasonable boundaries. These are CoinEx’s own stated reasons, not an independent finding.

The wind-down follows a fixed schedule. New user registration halted on September 15, referral rewards were discontinued, and futures positions moved to reduce-only mode. On September 22, all non-spot services cease, on-chain deposits stop except for the CET token, and open futures positions are forcibly settled. On September 29, spot trading ends. CET is automatically repurchased at $0.005 per token. The CSC and OneSwap products stop operating, and non-USDT assets are scheduled for disposal and conversion to USDT.

Withdrawals stay open until December 22, 2026 at 02:00 UTC. The final deadline for custody claims is August 22, 2028. Unclaimed USDT left after December 22, 2026 will incur a 5% monthly custody fee.

CoinEx said its asset reserve ratio sits above 100%. It said all user assets are fully backed and available for withdrawal. That is a company claim, not a verified audit finding.

The exchange carries a documented regulatory history. A June 2023 settlement with the New York Attorney General barred CoinEx from operating in New York and recovered approximately $1.7 million. In June 2026, CoinEx discontinued services in the European Economic Area (EEA) under the EU’s Markets in Crypto-Assets Regulation (MiCA) framework. In mid-2026, the exchange faced scrutiny over Iran-linked transaction flows and denied commercial ties to sanctioned entities, a denial that remains its own position, not a regulatory finding. This is a voluntary wind-down, not a regulatory enforcement action.

Why it matters

CoinEx frames the closure as a business decision driven by market conditions and compliance costs. This is CoinEx’s framing, not a confirmed cause. The pattern in the record is worth naming as analysis: a 2023 New York enforcement settlement, a MiCA-driven EEA exit in mid-2026, and Iran-related sanctions scrutiny in the same year all precede a full shutdown announced within months.

The stated reasons, a market downturn and rising compliance costs, are each plausible standalone explanations. Read together with the regulatory timeline, they suggest a smaller exchange absorbing the cost of tightening requirements across several jurisdictions at once. That is an inference, not a documented fact.

The multi-year asset return window is itself informative. Withdrawals stay open until December 2026, but custody claims run until August 2028. That gap suggests CoinEx expects a meaningful share of balances to go unclaimed, which is likely why the 5% monthly fee on unclaimed USDT was built into the schedule.

Practitioner angle

• Identify any institutional or customer exposure to CoinEx now. Confirm withdrawal before December 22, 2026 at 02:00 UTC, after which unclaimed USDT accrues a 5% monthly custody fee.
• Review historic transaction monitoring alerts tied to CoinEx counterparties, especially given the mid-2026 scrutiny over Iran-linked flows. Treat CoinEx’s denial of ties to sanctioned entities as a claim, not a clearance.
• Do not record CoinEx’s stated reserve ratio above 100% as a verified fact in any customer due diligence file. It is an unaudited company claim.
• Update customer risk profiles and onboarding records for clients who declare CoinEx as an exchange used or a source of funds.
• Log the compliance cost narrative for governance discussions. It is a data point on the sustainability of smaller crypto venues under tightening jurisdictional requirements, including MiCA in the EU.

The single action to take this week: find any CoinEx exposure and move funds before the withdrawal window closes.
