NEW YORK, April 2 (Reuters) - Global stocks rose sharply on Thursday and the price of government debt fell on optimism over efforts by world leaders meeting in London to solve the economic crisis and a change in U.S. accounting rules that will help troubled banks.
Oil prices surged more than 8.0 percent to above $52 a barrel after world leaders at the G20 summit agreed to pump an additional $1 trillion into the ailing global economy through extra funding for groups like the International Monetary Fund. For details see [
