The Federal Reserve has cut its target for a key interest rate to the lowest level on record and pledged to use "all available tools" to combat a severe financial crisis and prolonged recession.
The central bank on Tuesday said it had reduced the federal funds rate, the interest that banks charge each other, to a range of zero to 0.25 percent. That is down from the 1 percent target rate in effect since the last meeting in October. Many analysts had expected the Fed to make a smaller cut to 0.5 percent.
Federal Reserve Chairman Ben Bernanke and his colleagues also pledged to use "all available tools" as they struggle to contain a financial crisis that is the worst since the 1930s and a recession that is already the longest in a quarter-century.
