The UK's sanctions watchdog issued a penalty topping £4.7 million to Citigroup's UK operation for mishandling transactions under Russia-related restrictions. According to the Office of Financial Sanctions Implementation, the London branch of Citibank N.A. executed 970 transactions totaling over £19.7 million on accounts that, under the rules, should not have been active.
OFSI, part of the Treasury, said most breaches took place in the months after Russia invaded Ukraine in 2022, and noted that some of the transactions Citigroup voluntarily brought forward occurred as late as 2025. The agency called the mistakes "material and significant and they occurred across a wide range of business areas and systems within the bank," and added that certain affected accounts were operated by companies with ties to PJSC Sovcomflot, Russia's largest shipping firm.
"We are pleased to conclude this matter with OFSI," a Citi spokesperson said, adding that the unit engaged proactively and cooperated with the agency during the investigation. "We remain committed to working closely with sanctions authorities and supporting our clients through a strong and effective control environment." As of last year, Citigroup had wound down nearly all of its institutional banking business in Russia, and in November 2025 it received authorization from Russian President Vladimir Putin to sell its bank in the country.
