Coinbase Faces €21.5 Million Fine in Ireland After Major AML Oversight
Coinbase fined €21.5M by Ireland’s central bank over AML monitoring failures tied to €176B in unscreened transactions.
Coinbase has been fined €21.5 million by the Central Bank of Ireland for serious lapses in its anti–money laundering (AML) transaction monitoring system. The penalty, one of the largest ever imposed on a crypto exchange in Europe, follows failures that allowed more than 30 million transactions worth €176 billion to go unscreened between 2021 and 2022.
The Irish regulator found that the company’s automated systems were misconfigured, leaving critical gaps in transaction oversight. According to the Central Bank, these failures created opportunities for criminal actors to move funds undetected, weakening Ireland’s broader AML and counter-terrorism financing framework.
Coinbase acknowledged responsibility, attributing the problem to a coding error that disabled five of the company’s 21 monitoring scenarios. The exchange said it discovered the issue internally, corrected the faulty code, and re-screened all affected transactions. However, regulators noted that Coinbase took nearly three years to complete a retrospective review, during which it filed 2,708 suspicious transaction reports (STRs) to the Irish Financial Intelligence Unit.
Authorities stated that these reports included red flags related to serious crimes, ranging from money laundering and fraud to drug trafficking, ransomware, and child exploitation. In its statement, the Central Bank emphasized that “real-time transaction monitoring and the prompt filing of STRs are fundamental to the effectiveness of AML and CFT enforcement.” The failure to detect suspicious activity in time, it warned, “can seriously hinder law enforcement’s ability to investigate and prosecute criminality.”
Under the regulator’s Administrative Sanctions Procedure, Coinbase agreed to settle on an undisputed basis, avoiding lengthy legal proceedings. The company also received a 30% reduction from the original €30.6 million fine in recognition of its cooperation.
Despite the compliance breach, Coinbase remains focused on expanding its European presence. The company recently reported a strong third quarter, with revenue rising 25% to $1.9 billion. It is also exploring entry into the stablecoin market and is reportedly in advanced talks to acquire BVNK, a London-based payments firm, in a deal valued between $1.5 billion and $2.5 billion.
While Coinbase framed the incident as an isolated technical mishap, the fine underscores the growing scrutiny facing global crypto exchanges as regulators tighten oversight. Ireland, which has become a hub for several fintech and crypto firms, has been under pressure from the European Union to enforce stricter AML compliance across digital asset platforms.
The episode highlights how even the largest and most established crypto players remain vulnerable to operational oversights in a rapidly evolving regulatory landscape. For Coinbase, the settlement closes a difficult chapter but serves as a reminder that transparency and robust compliance systems are now inseparable from legitimacy in the crypto economy.
