Federal Reserve cut interest rates by 0.75%, delivering less than the markets hoped for despite the magnitude of the move.
The Fed's policy-making Federal Open Market Committee (FOMC) cut its short-term interest rate target to 2.25% from 3% - the most rapid pace of easing in years.

But it was less than the full percentage point investors had come to expect after the Fed's dramatic intervention to prevent Bear Stearns (BSC) over the weekend signaled a heightened degree of concern that the severe credit crunch had put the stability of the financial system at risk. (BSC dropped from last Thursday $57 to Monday's lowest $2.80!!)
What do all things mean to the mighty Dollar?In recent months, the dollar had fallen as foreign investors questioned the Fed's willingness to act against inflation, and investors seeking a hedge against both inflation and a weaker dollar had put money into commodities.
The Fed also on Tuesday lowered the discount rate it charges banks and brokers that borrow directly from the Fed by 0.75 percentage point to 2.5%, leaving the spread over fed funds at a quarter point.
But as the financial market crisis worsened last week and economic data disappointed, investors steadily upped their rate-cut forecasts to as high as 0.75 percentage point by the end of last week.
And after the Fed on Sunday lowered the discount rate by one-quarter point, extended $30 billion in financing to JP Morgan Chase (JPM) to complete its takeover of Bear Stearns and announced new liquidity measures on top of others that could pump hundreds of billions of dollars into credit markets, many economists concluded that anything less than 100 basis points would disappoint markets and threaten a renewed downward spiral.
The smaller-than-expected rate cut may also signal that officials are growing uneasy about the U.S. dollar's decline against other major currencies, which has pushed up prices of commodities like oil that are priced in dollars.
A 0.75-percentage-point cut signals "that the Fed does not harbor benign neglect toward the dollar, as has been the impression of late," said Miller Tabak strategist Tony Crescenzi in a research note before the Fed announcement.
