South Korea blocks 27 crypto exchanges with one website-level blitz, and the message to unregistered platforms is hard to misread: register, or vanish from Korean screens. The Financial Intelligence Unit (FIU) confirmed the sweep this week, extending years of app-store restrictions into full web access blocks across a broad slice of offshore venues.
The move lands as Seoul fine-tunes its wider digital-asset rulebook, and it gives the country’s registered operators something they have quietly wanted for a long time: fewer unlicensed competitors holding Korean users’ funds.
How South Korea Blocks 27 Crypto Exchanges From Reaching Users
The FIU, operating under the Financial Services Commission, ordered website access blocks after reviews by the Korea Communications Standards Commission on October 6 and 7. Domestic sites face outright service termination; overseas platforms get the website block, and regulators said they will chase any mirror addresses that pop up in response. The named list includes KuCoin, BitMart, MEXC, Phemex, BingX, Poloniex, BTCC, XT.com, Bitrue and CoinW – the full roster of 27 was not published.
These are exchanges operating without the local registration South Korea requires. The penalties for running unregistered virtual-asset business read like a threat with paperwork attached: up to five years in prison or a fine of 50 million won, roughly $37,000.
Why These 27 Platforms, and Why Now
Only 28 virtual asset service providers are registered with the regulator, and 44 unregistered operators have already been referred to investigators. The website blocks complete a campaign that started with mobile app restrictions on Google and Apple stores in 2025 – unregistered platforms could once hide behind an app; the browser was the last easy door.
Underneath the enforcement sits a bigger arithmetic problem. An estimated $110 billion in crypto left South Korean exchanges in 2025 under the country’s strict trading rules. Every blocked offshore venue is a small vote for keeping that money – or the next tranche of it – inside the regulated perimeter.
What Happens to Users Now
Regulators warned that customers of unauthorized platforms may struggle to recover funds, and industry umbrella group DAXA said it will help affected users withdraw assets. KuCoin said it respects local laws and is strengthening its compliance framework; BitMart and MEXC had no immediate comment.
Meanwhile, South Korea’s proposed Digital Asset Basic Law is still pending, intended to set the framework for issuance, trading, custody and supervision in one place. Enforcement without the full statute books is not ideal – but with 27 sites already dark, the regulator seems comfortable making the point while legislators finish the sentences.
