Royal Bank of Canada, Societe Generale subpoenaed in Libor probe
US investigators subpoena lenders over alleged rigging of interbank rate
Societe Generale, Royal Bank of Canada and Bank of America are among nine additional banks that were subpoenaed in New York and Connecticut's probe of alleged manipulation of Libor, a person familiar with the matter said.
The subpoenas, issued by New York attorney general Eric Schneiderman starting in August, brought to 16 the number of banks that had been subpoenaed in the states' investigation, said the person, who asked not to be identified.
Schneiderman and Connecticut attorney general George Jepsen are jointly investigating claims that banks rigged the London interbank offered rate, a worldwide benchmark for borrowing.
The same person said in August that seven banks were subpoenaed in their investigation, including JP Morgan Chase and Barclays.
The states are co-ordinating with "a much larger group of attorneys general", Susan Kinsman, a spokeswoman for the Connecticut attorney general, said last month.
Florida attorney general Pam Bondi has also issued subpoenas to more than a dozen financial institutions, including UBS, Deutsche Bank and HSBC Holdings.
