NEW YORK, Oct 13 (Reuters) - U.S. stocks headed for a sharply higher open on Monday as a push by governments around the world to pump money into the clogged banking system sparked relief among investors and credit markets showed signs of loosening up.
Stock markets leaped in Asia overnight and again in Europe, where the FTSEurofirst 300 <
>, an index of leading European shares, shot up more than 6 percent. Benchmark U.S. indexes were poised to open up 4 percent or more after Wall Street capped its worst week ever on Friday.Governments stepped up efforts to restore confidence in the tottering banking system by providing multibillion-dollar bank bailouts following weekend talks in Washington.
"The global markets are giving a nod of approval to what the governments, central banks and the U.S. Treasury are doing to boost confidence in the market place," said Peter Cardillo, chief market economist at Avalon Partners in New York.
"What we could see is a market that begins to stabilize. Obviously there's some questions about the plans. Are we going too far? Are we all becoming socialist? But the bottom line: the market needed to get some concrete plan and I think finally we've gotten something that's going to restore confidence."
S&P 500 futures <SPc1> rose 47.50 points and were above fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract.
Dow Jones industrial average futures <DJc1> jumped 348 points and Nasdaq 100 <NDc1> futures climbed 57.75 points. At their peak on Monday, the S&P 500 futures registered their biggest advance since Sept. 19 when Washington announced plans for a $700 billion bailout to mop up bad mortgage debts from banks' books.
U.S. trading was likely to be light, however, with the U.S. bond market closed for the Columbus Day holiday. Japanese markets were also closed for a national holiday on Monday.
Britain said it would spend up to $64 billion buying into top UK banks and Germany and France have drawn up similar steps. In the United States, Treasury Secretary Henry Paulson said Washington was developing plans to buy equity in financial institutions to halt the prolonged market turmoil.
Before the bell, the Financial Select Sector SPDR <XLF.A>, an exchange-traded fund which tracks the performance of the Standard & Poor's 500 financials group, jumped 4.6 percent.
Shares of Morgan Stanley <MS.N> rose 33 percent to $12.90 before the bell after Japan's Mitsubishi UFJ Financial Group <8306.T> announced it had bought a $9 billion stake in the beaten-down securities firm that has now turned into a bank holding company. For details see [
].Spain's Banco Santander <SAN.MC> is in advanced talks to buy full control of Sovereign Bancorp Inc <SOV.N> in a deal valued at $2.5 billion, according to a source familiar with the matter. Before the bell, Sovereign Bancorp shares jumped more than 10 percent to $4.20.
Shares of General Motors <GM.N> climbed more than 17 percent to $5.75 following news that the automaker has held merger talks with Chrysler LLC. [
