South Korea blocks 27 crypto exchanges, including KuCoin

South Korea's financial regulators have blocked 27 unregistered crypto exchanges, including KuCoin and BitMart. The action was reported on 13 October 2026. The enforcement extends beyond earlier mobile app restrictions to full website blocking. The stated rationale is proactive investor protection, acting before users report losses rather than after.

This is a meaningful escalation in method. Blocking app stores is a softer intervention. Blocking websites is a harder, more visible barrier for retail users. It signals that Korean regulators are willing to use infrastructure-level tools to enforce registration requirements.

South Korea is one of the highest retail crypto trading volumes per capita in Asia. Redirecting that volume matters at scale. The 27 blocked exchanges include platforms with meaningful Korean user bases. Those users now face real friction accessing their preferred platforms, either through workarounds such as VPNs or by migrating to registered domestic alternatives.
