BRUSSELS
The European Commission also said it would charge broker ICAP soon for suspected manipulation of the yen Libor financial benchmark.
U.S. and European regulators have so far handed down some $6 billion in fines to 10 banks and brokerages for rigging the London interbank offered rate (Libor) and its euro cousin Euribor while prosecutors have also charged 16 men with fraud-related offences.
The three banks and ICAP, which refused to settle the case in December, could face penalties of up to 10 percent of their global turnover if found guilty of breaching EU antitrust rules.
JPMorgan said the EU charges were without merit and that it would defend itself while Credit Agricole said it would examine the charge sheet. HSBC said it would defend itself vigorously.
In December a record 1.7-billion-euro ($2.3 billion) fine was levied on six banks including Deutsche Bank, Royal Bank of Scotland and Citigroup for similar offences. The lenders settled their charges and received a 10-percent cut in their fines.
