The U.S. Federal Reserve on Wednesday, in a surprise move, said it will buy up to $300 billion worth of longer-term U.S. government debt over the next six months and expand purchases of mortgage-related debt to help ease credit market conditions.

The Fed this week began taking bids for a program designed to spur student, auto, credit card and small business lending, and it said on Wednesday it would consider expanding that program to cover a wider array of assets.
The consumer and small business credit program will initially aim to inject $200 billion into the market for securities backed by these loans, but the Fed has already said that program could be ramped up to $1 trillion.
While the Fed has gone to extraordinary lengths to try to get credit flowing, the economy is still in a nose dive.
U.S. gross domestic product shrank at a 6.2 percent annual rate in the fourth quarter, the deepest contraction since early 1982, and the unemployment rate has shot to a 25-year high of 8.1 percent.

After a $700 billion bank bailout approved by Congress in October and a $787 billion tax-cut and spending bill passed this year to lift the economy, public resentment at the large tab taxpayers are picking up has grown more strident.
