South Korea blocks 27 crypto exchange sites including KuCoin

South Korea moved to block 27 unregistered crypto exchange websites, including KuCoin and MEXC, from users inside the country. The order, announced on October 13, 2026, hit platforms that never registered under the country's anti-money laundering law.

Behind the order is the Financial Intelligence Unit (FIU), the anti-money laundering arm of the Financial Services Commission. A media and communications review panel approved the request over two sessions, on October 6 and 7, before the FIU made it public. The agency said it will now act as soon as it detects unregistered activity, without waiting for victim complaints or a court ruling.

Which platforms are on the list

The FIU named 27 sites in all. Reports listed KuCoin, MEXC, BitMart, Phemex, BingX, XT.com, Bitrue, Poloniex, BTCC, Pionex and WEEX among them, with several more running under Korean-language brands. Most are large offshore exchanges that take Korean users but hold no license in the country.

Blocking works in two ways. Korean internet providers cut off access to the foreign sites, and any platform operating from inside the country is ordered to stop. The FIU also said it will chase replacement web addresses, so a blocked exchange cannot simply reopen under a fresh URL.

What the regulator is enforcing

Registration is the heart of it. Under the Act on Reporting and Using Specified Financial Transaction Information, any exchange serving Korean users must report to the FIU and meet security and anti-money laundering standards. An operator that skips this step is treated as illegal, even if it runs cleanly everywhere else.

Few firms have cleared that bar. The Korea Financial Intelligence Unit counted just 26 registered virtual asset service providers in its survey for the first half of 2026, published on October 1. Everyone outside that short list is, by law, operating without permission. The FIU said it has referred 44 unregistered operators to investigators so far.

Penalties are steep on paper. Running an unregistered exchange can bring up to five years in prison or a fine of up to 50 million won, or roughly $37,000. This web block extends a push that began with app stores, where regulators had already stopped unregistered operators from offering new app installs or updates.

What it means for people who used these sites

Regulators warned that customers of unregistered platforms may struggle to get their money back. The FIU urged users to check whether an exchange is registered and to move their coins into a wallet they control. Authorities said they would work with the local exchange group DAXA to guide users through withdrawals.

KuCoin pushed back gently. A spokesperson said the exchange respects the laws of every market it works in and that compliance stays central to its strategy. "User assets remain safe and secure, and we will communicate any further updates through our official channels," KuCoin said. MEXC and the other named platforms had not issued public statements by the time the order went out.

Blocks can be dodged. A determined trader can still reach a banned site through a VPN or a mirror address, which is why the FIU said it will keep hunting for new URLs rather than treat the first block as final. The order sets no end date, and the FIU did not say exactly when each site goes dark.

What to watch

Two things will show whether the order bites. The first is enforcement, meaning whether blocked exchanges resurface under new addresses faster than the FIU can act on them. The second is registration, and whether any of the 27 decides the Korean market is worth the paperwork. DAXA, the group representing Korea's licensed exchanges, has been asked to help users pull funds out, which hints at how many people the blocks may touch.

There is also a bigger law in the background. South Korea is drafting a Digital Asset Basic Law meant to set clearer rules for the industry, and how it treats offshore exchanges could decide whether blocks like this become routine or give way to a licensing route like the ones taking shape elsewhere in Asia. For now, the message to unregistered operators is blunt. Register, or go dark.
