South Korea moves to block 27 unregistered overseas crypto exchanges
In brief
- South Korea's FIU announced a block on 27 unregistered overseas exchange websites on October 13, 2026.
- KCSC deliberations on October 6 and 7 preceded the decision.
- FIU cited asset theft, fraud and data leaks, and said users get no investor protections.
- Offshore fees reportedly ranged from 1.5% to 10%, versus about 0.16% at licensed exchanges.
Why the FIU says it acted
The FIU called the block a user-safety measure, according to Crypto Briefing. The regulator pointed to asset theft, fraud and data leaks on platforms that sit outside the domestic regulatory perimeter, and it warned that these exchanges offer no investor protections.
Fees were part of the case too.
The FIU said unregistered platforms charge excessively high fees compared with registered exchanges. Crypto Briefing reported that offshore venues charged average trading fees of 1.5% to 10%, while major licensed exchanges charged around 0.16% (some offshore fees were reportedly up to 62 times higher than what registered platforms charge).
The KCSC is what makes the order enforceable. It's the body that handles online content oversight in South Korea, so it's the one that can actually block access to a website.
A squeeze that's been building
This isn't the first move against offshore VASPs. Credit card transactions at unregistered firms were restricted in May 2024. Google Play then required VASP registration starting January 28, 2026, and both Google Play and Apple have restricted unregistered exchange apps, so users can't download or update them through those stores.
Registered South Korean VASPs have also been told not to facilitate transfers to unregistered overseas operators.
The registry numbers
As of October 2026, a cumulative 44 unregistered operators had been referred to authorities, and 12 of those referrals came in June, Crypto Briefing reported. Only 27 to 28 domestic platforms had successfully registered with the FIU, per the same report. That puts the number of offshore sites now being blocked roughly level with the number of domestic platforms that have made it through registration.
