Aug. 17 (Bloomberg) -- The Federal Reserve lowered the interest rate it charges banks and acknowledged for the first time today that an extraordinary policy shift is needed to contain the subprime-mortgage collapse that began roiling the world's financial markets two months ago.
The Fed, in a surprise announcement in Washington, cut the so-called discount rate by 0.5 percentage point, to 5.75 percent. Policy makers dropped language indicating their bias toward fighting inflation, and instead highlighted a rising threat to economic growth. That suggests officials will reduce their benchmark rate when they meet Sept. 18, economists said.
``This telegraphs their intention to cut rates at the next meeting,'' said Chris Rupkey, senior financial economist at Bank of Tokyo-Mitsubishi UFJ Ltd. in New York. ``This discount rate cut calms the market and helps financing.''
This is the first unanticipated reduction in borrowing costs between scheduled meetings since 2001, and Ben S. Bernanke's first as Fed chairman. Officials kept the benchmark federal funds rate target for overnight loans between banks at 5.25 percent. Policy makers next meet to set the rate on Sept. 18. Futures indicate traders anticipate at least a quarter-point cut.
Stocks Climb
The Fed's decision ignited a rally in stocks from Europe to the U.S. The Standard & Poor's 500 index climbed the most in four years, rising 2.5 percent, to 1,445.94. The Dow Stoxx 600 Index of European shares added 2.1 percent to close at 359.65.
