Aug. 20 (Bloomberg) -- The International Monetary Fund may raise its forecast for the global economic rebound as signs of growth return, said John Lipsky, the fund’s first deputy managing director.

“It’s possible,” Lipsky said today in a Bloomberg Television interview at the Kansas City Federal Reserve Bank’s annual symposium in Jackson Hole, Wyoming. “We’re on track, in broad terms, for a kind of recovery we’d anticipated.”

The Washington-based lender with 186 members last month predicted the world economy will expand 2.5 percent in 2010 after contracting 1.4 percent this year. Since then, data has shown growth returning to the economies of Japan, France and Germany as the financial system stabilizes and business confidence returns.

Policy makers should maintain their efforts to fan growth and not be hasty to raise interest rates or taxes, Lipsky said. “To turn this into a self-sustaining recovery is going to take a while and it’s not going to be a quick and sharp recovery,” he said.
