Seoul, April 13, 2026. South Korea's Financial Intelligence Unit (KoFIU) has formally fined cryptocurrency exchange Coinone and imposed a partial business suspension after finding the platform violated the country's primary anti-money laundering law, the Act on Reporting and Using Specified Financial Transaction Information. The action, announced Monday by Yonhap News Agency, marks the latest enforcement step in a sequential regulatory campaign targeting all five of South Korea's largest crypto exchanges.

The specific fine amount had not been publicly confirmed ahead of Monday's announcement. Verse Press will update this article when the full KoFIU disclosure is available. Based on the enforcement pattern seen with Coinone's peers, the penalty could be substantial: KoFIU fined Bithumb 36.8 billion won (roughly $24.6 million) in March 2026, and Upbit 35.2 billion won (roughly $25.4 million) in November 2024. Both exchanges also received partial operational suspensions. Among the five targeted exchanges, Korbit received a confirmed fine of 2.73 billion won (approximately $1.9 million) along with an institutional warning, while Gopax's penalty remains pending. Analysts had previously estimated combined penalties across all five targeted exchanges could exceed 150 billion won, or approximately $110 million.

The partial suspension imposed on Coinone is expected to follow the same operational restriction model used against Upbit and Bithumb. Under that model, new users are blocked from transferring virtual assets to and from external wallets. Existing accounts continue operating, which limits immediate disruption for most users but signals tighter compliance scrutiny going forward. Coinone confirmed, in an April 8 statement, that it had received advance notice from financial authorities in late March 2026 and said it is "actively presenting its case."

Coinone was inspected by KoFIU in April 2025 as part of a campaign that covered all five major South Korean exchanges: Upbit, Bithumb, Coinone, Korbit, and Gopax. The violations identified across the broader campaign included failures to verify customer identities (KYC), failure to flag or report suspicious transactions, acceptance of unverified identity documents, and processing transactions with unregistered offshore VASPs (Virtual Asset Service Providers).

The scale of documented lapses at other exchanges illustrates how systemic these failures were. KoFIU found more than 8.6 million AML violations at Upbit, including 5.3 million customer identity failures, 3.3 million transactions processed for unverified users, and the acceptance of photocopied identity documents. According to FIU enforcement documents reported by CoinDesk, investigators documented roughly 3.55 million KYC failures and 3.04 million cases of improperly blocked transactions at Bithumb.

Founded in 2014, Coinone is one of South Korea's oldest operating crypto exchanges. It holds a registered VASP (Virtual Asset Service Provider) license under KoFIU, carries ISMS security certification, and is a member of DAXA (Digital Asset eXchange Alliance), the industry's self-regulatory body. Since November 2022, the platform has processed Korean won deposits and withdrawals through a real-name account partnership with Kakao Bank, having previously partnered with NH Bank before making that switch. The fact that DAXA membership and full licensing did not shield Coinone from enforcement reinforces that regulatory standing does not substitute for operational compliance.

South Korea's AML framework has been in place since 2021, when VASPs were required to register with KoFIU, link to licensed domestic banks for real-name verified accounts, and implement the Travel Rule for crypto transfers above 1 million won (approximately $680). The Travel Rule requires exchanges to collect and transmit sender and recipient information on qualifying transactions. KoFIU is now finalizing rules to eliminate that threshold entirely, extending the Travel Rule to all crypto transactions. The change is expected to be completed in the first half of 2026.

In parallel with the domestic campaign, KoFIU has moved against 14 unregistered foreign exchanges, including KuCoin, MEXC, Phemex, and Bitget, by coordinating with South Korea's telecom regulator to block access to their platforms through app stores and network-level restrictions.

The enforcement wave carries practical implications beyond South Korea's borders. The country is one of Asia's most active retail crypto markets, with high per-capita trading volumes and deep fiat-to-crypto liquidity. One industry observer cited in BanklessTimes noted: "The FIU examined all platforms using the same AML standards. As a result, there are limited expectations that the penalty amounts will vary significantly."

Analysts at ainvest.com have argued that South Korea's approach could prompt regulators in India, Vietnam, and Indonesia to accelerate their own oversight frameworks.

For exchanges and regulators in markets such as Nigeria, Kenya, and India, where formal crypto licensing regimes are still maturing, the Korean experience offers a pointed lesson: compliance infrastructure at scale is not just a best practice but a legal baseline. Three points stand out for emerging markets:

• KYC failures at millions of transaction points occurred even at fully licensed, well-established platforms.
• The Travel Rule threshold gap has been exploited and is now being closed.
• The real-name bank account requirement that underpins Korea's safeguards remains difficult to replicate in markets with lower banking penetration, but regulators there are watching closely.

For projects listed on Coinone, reduced onboarding capacity for new Korean retail users during the suspension window may translate into lower liquidity for KRW trading pairs. Teams with concentrated exposure to a single Korean exchange should treat this as a signal to diversify their regional market access, even as all DAXA-member exchanges face similar compliance headwinds.
