A global investigation into manipulation of interbank lending rates widened with Britain's fraud squad taking up the case and Germany's markets regulator had launched a probe into Deutsche Bank.
Authorities in the United States, Europe, Japan and Canada are examining more than a dozen big banks over suspected rigging of the London Interbank Offered Rate (Libor). Britain's Barclays has so far been the only bank to admit wrongdoing, agreeing last week to pay a fine of more than $450 million. The SFO will now assemble a case team to pursue an investigation - although it could take years. A spokesman noted that its remit would not be confined to Barclays.
