PARIS, FRANCE, May 14, 2009 (AFP) - The International Energy Agency forecast on Thursday a 28-year record annual drop in world oil demand, and further trimmed its forecast for 2009.

The agency estimated global oil demand this year at 83.2 million barrels per day (bpd), three percent lower than last year, "and the sharpest single year's fall since 1981," in its monthly oil market report.

Last month it had estimated 2009 demand at 83.4 million bpd.

"Forecast global oil demand for 2009 has been revised down slightly (since last month) following weaker-than-expected preliminary data in various regions," it said.
