Korea FIU Flags Possible 6-Month Bithumb Ban

South Korea’s Financial Intelligence Unit (FIU) has pre-notified crypto exchange Bithumb of major potential sanctions, including a six-month partial business suspension and disciplinary action against its CEO, according to local reporting. The case centers on alleged AML and KYC compliance failures under the country’s Special Financial Information Act.

The FIU’s notice is not final. A sanctions review committee is expected to meet this month to determine the final penalty level.

What the FIU says Bithumb did wrong

According to the report, the FIU flagged two main issues:
Bithumb allegedly transacted with overseas unreported virtual asset service providers (VASPs) and failed to properly meet customer due diligence (KYC) obligations.

These are standard AML “red lines” for regulated exchanges: who you do business with (counterparty screening) and how thoroughly you verify customers (KYC).

What “partial suspension” would actually restrict

The reported measure is narrowly targeted: it would only restrict virtual asset transfers (withdrawals) for new members.

Existing users would still be able to use KRW deposits/withdrawals, crypto deposits/withdrawals, and trading as normal, per the report. In other words, the restriction is aimed at new customer outbound crypto transfers, not shutting down the exchange.

Why the FIU is escalating enforcement now

The report places Bithumb’s case in a broader enforcement trend:

• The FIU previously imposed a three-month partial suspension and a ₩35.2 billion administrative fine on Upbit operator Dunamu for similar issues.
• Korbit reportedly received a ₩2.73 billion fine and an institutional warning earlier this year.

The message is consistent: South Korea’s AML supervisor is applying progressively tougher pressure on major domestic exchanges, especially around KYC and overseas counterparty compliance.

Bithumb says the sanctions are not final

Bithumb said the action is still at the pre-notification stage, meaning penalties may be adjusted during the sanctions review. The exchange also emphasized that any restriction would apply only to crypto transfers (withdrawals) for newly registered users, not to the broader user base.

Why it matters for crypto

• South Korea is signaling that AML and KYC enforcement is moving from warnings to operational restrictions, even for top-tier exchanges.
• A “new users only” transfer cap can still hit growth: it makes onboarding and immediate self-custody withdrawals harder.
• This sets a precedent for how regulators can target risk corridors without fully halting trading activity.
• Similar cases could increase compliance costs and tighten onboarding across Korean exchanges.

What to watch next

• The FIU’s sanctions review committee decision this month: whether the six-month duration is confirmed or reduced.
• Whether CEO discipline is finalized and what form it takes (not specified in the report).
• Next enforcement actions: the report says Coinone and GOPAX are expected to face sanctions reviews in sequence.
• Any product or UX changes at Bithumb for new users (onboarding, withdrawal limits, cooling-off rules).
