Regulators approved blocking unregistered platforms that serve Korean users and said future sites will be blocked as soon as they are detected. Fees at unregistered venues ran as high as 62 times those of Korea's licensed exchanges.
South Korea has closed another door to offshore crypto trading. The fee gap regulators published suggests why they wanted it shut.
Twenty-seven trading sites run by crypto operators that never registered in Korea will be cut off, the country's Financial Intelligence Unit announced Tuesday. The broadcast and communications standards regulator signed off on the request after two days of review last week. Users in Korea will be unable to reach the offshore-hosted platforms, and any hosted at home will be shut down. The platforms named include KuCoin, MEXC and BitMart, along with Phemex, Bitrue, Poloniex and BingX, according to local reports.
Last year authorities blocked the mobile apps of many of the same exchanges in Korean app stores. The website block closes the browser route.
The new procedure
The bigger change is procedural. From now on the FIU intends to move against a site the moment it spots unregistered operations, "even without a separate damage report," rather than waiting for a court or for customers to lose money. Forty-four unlicensed operators have already been passed to investigators, and copycat sites that pop up at new web addresses will be targeted too.
Operating without registration can bring up to five years in prison or a fine of up to 50 million won. The law covers foreign operators that market to Koreans, offer Korean-language sites or accept won payments. Against that, the number of registered crypto businesses in the country stands at 28.
The fee gap
A June investigation by the FIU and the Digital Asset eXchange Alliance found average fees of 1.5% to 10% at unregistered venues, compared with 0.16% at Korea's five won-based exchanges. At the top of that range, fees were about 62 times higher.
The FIU urged users to withdraw assets from unregistered platforms and said the alliance will help customers whose withdrawals are affected. A KuCoin spokesperson said "user assets remain safe and secure."
Where the volume could go
Korea is one of the world's largest retail crypto markets, and offshore exchanges offer leverage and early token listings that the won exchanges do not. Blocking web access could steer more trading toward licensed venues such as Upbit and Bithumb, though users may turn to virtual private networks or mirror sites.
Market implications
One reading is that the block shifts volume onshore. Licensed exchanges gain flow, offshore derivatives lose Korean users, and the gap between local and global prices could narrow as more trading moves to regulated venues.
A second reading is that the effect will be limited. The app ban did not stop browser access, website blocks are easy to bypass, and the FIU is already planning for replacement sites.
What to watch
Whether any of the 27 exchanges registers or partners with a Korean firm, trading volume on Upbit and Bithumb, and a separate court rule, reported to take effect Nov. 1, that standardizes the seizure of crypto for unpaid debts will show how far the crackdown reaches.
