Regulators in the US and UK fined JP Morgan Chase $920 million for actions tied to its 2012 "London whale" trading debacle, according to an announcement by regulators on Thursday.

The US Securities and Exchange Commission, the Office of the Comptroller of the Currency, the Federal Reserve and the UK's Financial Conduct Authority charged the company civilly with poor controls surrounding the giant bet, which ultimately cost the company more than $6 billion. The announcement of the settlements, which had been expected, is one of the largest fines a bank has ever had to pay over a single trading strategy.
