Oil prices rose above $40 a barrel on Monday, up nearly 8 percent on the previous session, after violence between Iarael and Hamas served as a reminder of tensions that could threaten crude supplies from the Middle East.
Energy investments have taken a hit around the world from the global economic crisis, Birol said.
"The projects aimed to develop oil fields are being postponed. This poses a great risk. Demand will pick up when the world economy starts recovering," he said.
"Because oil supply will be limited due to today's postponed investments, a serious supply-demand problem will emerge in 2010," Birol said.
He expects to see a transition from an energy market dominated by multinational oil companies to a market ruled by national companies, he said.
"For that reason, we may see oil and gas prices zigzaging more in the future," he said.
