South Korea regulators impose unified 24–72 hour withdrawal delays across exchanges

South Korea tightens crypto withdrawals. Regulators and exchanges will enforce one standardized delay system across all registered trading platforms.

The FSC, FSS and DAXA align rules to curb fast voice‑phishing cash‑to‑crypto flips. News1 reports the aim is to slow exits so banks can flag suspicious transfers.

Exchanges must standardize “withdrawal‑delay exception” criteria. Exception accounts get intensive monitoring. News1.

Past loopholes came from exchange‑by‑exchange rules. Scammers moved dirty cash into crypto and out before freezes hit. The Korea Times.

Since May 2025, platforms have held withdrawals 24–72 hours after deposits. Exemptions varied by account age, activity, size, and history. Between June and September 2025, 59% of fraud‑linked accounts sat in these exception buckets. Authorities now target under 1% of users in exceptions, with tighter KYC, source‑of‑funds checks, annual re‑verification, and pattern‑tracking systems. News1.

Immediate withdrawals remain possible for genuine settlement needs under stricter scrutiny. News1.
