The regulator dished out its largest ever fine to the bank of £59.5m bringing the total cost to the firm in fines to £290m, including US penalties.
Chancellor George Osborne today revealed HSBC and Royal Bank of Scotland are also being investigated for Libor fixing.
The BBA says: “The BBA is shocked by yesterday’s report about Libor. The banks which contribute to the Libor rate must meet the necessary obligations to their regulators.
“The BBA has proactively co-operated with the authorities at every stage and will continue to work with the regulatory investigations into Libor, submitting information and making staff available for interview.”
A review into Libor was launched in March that will consider how rates are set in the future.
