Cryptocurrency exchange OKX is under renewed regulatory scrutiny in Europe after Maltese authorities issued a major fine for violations of Anti-Money Laundering (AML) laws.

Malta’s Financial Intelligence Analysis Unit (FIAU) fined Okcoin Europe — OKX’s Europe-based subsidiary — 1.1 million euros ($1.2 million) after detecting multiple AML failures on the platform in the past, the authority announced on April 3.

While admitting that OKX has significantly improved its AML policies in the past 18 months, the authority “could not ignore” its past compliance failures from 2023, “some of which were deemed to be serious and systematic,” the FIAU notice said.

OKX was among the first crypto exchanges to receive a license under Europe’s new Markets in Crypto-Assets (MiCA) regulation via its Malta hub in January 2025.

The news of the $1.2 million penalty in Malta came after Bloomberg in March reported that European Union regulators were probing OKX for laundering $100 million in funds from the Bybit hack.

Bybit CEO Ben Zhou previously claimed that OKX’s Web3 proxy allowed hackers to launder about $100 million, or 40,233 Ether (ETH), from the $1.5 billion hack that occurred in February.

This is a developing story, and further information will be added as it becomes available.
