Geithner defends U.S. response to 2008 Libor concerns
Geithner, then head of the New York Fed, sent an email to Bank of England Governor Mervyn King in June 2008, recommending six ways to enhance the credibility of Libor after Barclays had flagged concerns as early as 2007.
U.S. regulators set in motion a "very, very powerful enforcement response," Geithner said at the CNBC Institutional Investor Delivering Alpha conference, adding more enforcement on Libor is yet to come.
