Mr Bernanke's term ends at the start of next year
The Federal Reserve has maintained its huge bond-buying programme and has predicted a pick-up in growth in the US economy.
It said that it would hold its key rate at near zero and keep buying $85bn (£56bn) in bonds every month to help lower long-term interest rates.
Markets have begun debating when the US central bank may end its asset purchase programme.
Earlier, US economic growth for the second quarter was more than expected.
