South Korea says it is considering a ban on domestic cryptocurrency trading, as authorities raid local exchanges like Coinone, Bithumb for alleged tax evasion
Context & Ripple Effects
Seoul's stance has hardened fast: just weeks after floating a capital-gains tax on crypto trading and an account ban for minors, the government is now weighing an outright prohibition on domestic trading — and backing the fiscal angle with force, raiding Coinone and Bithumb over alleged tax evasion. The two exchanges are the country's dominant venues, so both the threat and the raids land on the same small set of operators.
First-order effects
- Coinone and Bithumb are immediately under criminal-investigation pressure, with their tax treatment of trading revenue now subject to seizure-and-audit tactics rather than negotiation.
- Korean retail traders face the prospect of losing legal domestic on-ramps entirely, converting a December tax question into an existential one for local exchanges.
Second-order effects
- Trading activity pushed out of licensed domestic venues migrates to offshore platforms — the dynamic that later led Seoul to block access to 16 unpermitted foreign exchanges including KuCoin and MEXC.
- Offshore operators read the same signals early: Binance and others proactively halted Korean-won trading ahead of tightening rules, trading short-term volume for regulatory safety.
Third-order effects
- The ban-consideration episode marks the start of a cycle where each crackdown displaces activity offshore, forcing the state to escalate from raids to border-level controls and eventually to the account-monitoring system deployed alongside its 2024 exchange law — supervision replacing prohibition as the end state.
The trend: South Korea's crypto policy is oscillating between prohibition threats and surveillance-based oversight, with each domestic squeeze pushing volume offshore and pulling the state toward cross-border enforcement.
