Deep Dive
1. AML and Travel Rule Tightening
South Korea is closing key AML gaps and pushing real-time surveillance. Officials plan to expand the travel rule to transfers below 1 million KRW and are considering an account suspension tool to freeze funds tied to serious crimes, alongside 24/7 abnormal-trading monitoring at exchanges policy brief. A parallel update notes the same thrust to stop smurfing and broaden oversight to more intermediaries regulatory update.
Expect stricter KYC on small transfers and more flags or temporary holds when patterns look suspicious, which can slow withdrawals but improve abuse prevention.
2. Enforcement Is Active (Korbit Case)
Enforcement has teeth. The FIU imposed an institutional warning and a ?2.73B fine on Korbit after finding about 22,000 KYC/AML lapses and other control failures in an on-site inspection FIU action via Yahoo Finance. A separate report details the FIUs tightening stance and similar actions at larger venues, reinforcing that compliance gaps now carry material penalties enforcement roundup.
Exchanges will raise diligence standards and automate checks. Users may see more re-verification prompts; smaller platforms could face higher costs or consolidation.
3. Technical Standards and Incident Response
Korea announced national security standards effective in 2026 that explicitly cover four areas for exchanges and VASPs: compliance systems, blockchain infrastructure security, digital wallet safeguards, and smart contract risk standards note. Operationally, Korean exchanges also moved fast on the recent Flow network issue, placing FLOW on watchlists and pausing flows as details emerged FLOW watchlist report, with the underlying incident described in a separate market report incident summary.
Expect more rigorous audits and wallet-key controls over the next year. In live incidents, Korean venues may act conservatively with freezes and reviews to protect users.
Conclusion
Koreas exchange security posture is shifting from reactive to proactive: stricter AML/travel-rule coverage, visible enforcement, and codified 2026 technical standards. Near term, users should expect tighter identity checks and occasional pauses when networks or tokens face incidents, with the trade-off of improved protection against abuse and counterparty risk.
