NEW YORK, Feb 26 (Reuters) - U.S. stocks rose on Tuesday on news of a $15 billion buyback plan from IBM and on remarks by a Federal Reserve top official that the weak economy is a bigger worry than inflation, while upbeat bank results drove European shares higher.
Crude oil surged past $100 a barrel in the U.S. and set a record price in London, lifting the shares of oil companies and helping push all three major U.S. stock indexes up more than 1 percent.
Oil drew support from cold weather in Europe and the United States, as well as the view from the president of the Organization of Petroleum Exporting Countries that the group will not raise output at its meeting next week.
The vice chairman of the Federal Reserve, Donald Kohn, speaking in North Carolina, said the danger the U.S. economy will weaken further is a bigger worry than higher inflation. His comments suggested the Fed will cut interest rates further, pushing the dollar to extend losses.
U.S. stocks moved higher after International Business Machines Corp <IBM.N> announced its buyback program, offsetting dire U.S. economic data that pointed to a sharp jump in inflation, a plunge in consumer confidence and more bad news from the beleaguered housing market.
"The market is looking for positives. IBM's a big component of the market, it's a large weighting, that combined with Ambac and the move late yesterday is giving short-term direction in the market," said Mark Schlarbaum trader, Global Capital Management Conshohocken, Pennsylvania.

In currency markets, the dollar extended losses after the remarks by the Fed's Kohn.
Kohn said in a speech at the University of North Carolina at Wilmington that he did not expect recent elevated inflation rates to persist.
"In my view, the adverse dynamics of the financial markets and the economy have presented the greater threat to economic welfare in the United States," Kohn said.
The euro rose to a session high of $1.4914 <EUR=>, versus $1.4902 before Kohn's comments. Against the yen, the dollar fell to 107.60 yen <JPY=>, a decline of 0.4 percent on the day.

Euro zone government bond prices slipped, pushing shorter-dated yields to a three-week peak as investors mulled the timing of European Central Bank interest rate cuts after upbeat German sentiment data.
