The UK’s Office of Financial Sanctions Implementation (OFSI) has fined Citibank N.A. London Branch £4.73 million ($6.35 million) for processing 970 payments worth £19.72 million that violated Russian sanctions regimes.
The UK’s Office of Financial Sanctions Implementation (OFSI) has fined the London branch of Citibank £4.7 million for serious failures in its sanctions monitoring systems. The penalty marks OFSI’s largest bank fine since the start of Russia’s invasion of Ukraine.
An investigation revealed that Citibank’s London operation processed 970 prohibited transactions worth nearly £19.7 million, highlighting significant gaps in the bank’s internal controls meant to prevent illegal money flows to sanctioned Russian entities.
Following Russia’s invasion of Ukraine, the UK government implemented strict economic sanctions targeting Russian financial institutions, businesses and designated individuals. Financial institutions were required to upgrade their screening tools to ensure no funds moved through sanctioned channels.

However, OFSI’s inquiry found that Citibank’s London branch allowed nearly 1,000 unauthorized payments to clear due to internal oversight flaws including issues with automated transaction monitoring and payment screening filters. These flaws led to inadequate flags for designated Russian individuals and entities as well as delays in updating internal compliance databases following government policy updates.
The £4.7 million penalty reflects the severity and volume of the violations, serving as a clear warning from UK regulators to global financial firms operating within the country.
Regulators emphasized that major banking institutions are expected to maintain robust, real-time compliance systems capable of enforcing government sanctions immediately.
While Citibank cooperated with the inquiry and took steps to rectify its internal oversight mechanisms, OFSI underscored that operational oversight failures on this scale warrant heavy financial penalties to maintain the integrity of the international financial system.
