LONDON, May 22 (Reuters) - Britain's banking and

financial regulators said on Wednesday they had fined U.S. bank

Citigroup ( C/PN ) more than 61.6 million pounds ($78.54 million)

for failures in its trading systems and controls.

The fine is one of the largest for controls breaches in the

UK since the global financial crisis in 2008-2009.

The Prudential Regulation Authority said it fined Citigroup

Global Markets Limited 33.88 million pounds for failings in its

trading systems and controls between 1 April 2018 and 31 May

2022. That fine had been reduced by 30% after Citi agreed to

resolve the issue.

The Financial Regulation Authority said it fined Citi 27.76

million pounds after an investigation into similar matters.
