South Korea Imposes 5-Minute Audit Rule On Crypto Platforms

Bithumb has pushed its stock market listing past 2028, citing the need to overhaul its accounting systems and internal controls after a high-profile crypto payout error drew scrutiny from South Korean regulators.

Regulator Steps In After Industry Audit

The Financial Services Commission announced Monday that all crypto exchanges operating in the country must now reconcile their internal records with actual asset holdings on a five-minute cycle.

The directive followed an emergency inspection triggered by Bithumb’s February blunder, in which the exchange accidentally sent 620,000 Bitcoin to 249 users during a rewards promotion.

Bithumb recovered nearly all of it the same day — 99.7% — and used company funds to cover the remaining 1,788 BTC that had already been sold.

What the inspection turned up across the broader industry alarmed regulators. Three of South Korea’s five largest exchanges were checking their books just once every 24 hours. Systems meant to pause trading when major discrepancies were detected were found to be inadequate.

Sweeping Operational Changes Now Required

Under the new rules, exchanges must build automated systems that match ledger records to actual wallet balances every five minutes. They are also required to set clear thresholds that trigger automatic trading halts when something looks off.

High-risk activities — promotional payouts, for example — will need third-party reviews and sign-off from multiple internal levels before going through. High-risk accounts must be separated, and automated payment verification tools will become mandatory.

External audits are changing too. Quarterly reviews are out. Monthly audits are in. Exchanges will also need to publish detailed breakdowns of asset balances by both wallet and ledger.

The FSC said it and the Digital Asset Exchange Alliance plan to finish drafting the updated rules before the end of April.

Bithumb’s listing plans have now been pushed back at least three years from its original 2025 target. The exchange has brought in advisory firm Samjong KPMG and said it will spend 2027 focused on tightening its financial policies and controls before making another run at going public.

Separately, Naver Financial has delayed its planned share swap with crypto firm Dunamu by about three months. A shareholder vote is now set for Aug. 18, with the deal expected to close by Sept. 30.

South Korea has long been one of the most active countries in regulating crypto markets. These latest moves signal that pressure is intensifying — and that exchanges can expect less room for error going forward.
