Nov. 18 (Bloomberg) -- Crude oil rose to the highest level since before the U.S. invasion of Iraq in March on signs that inventory gains will be limited.
Oil supplies are ``too low'' and may not be able to meet increased demand in the event of a colder-than-normal winter, said Claude Mandil, the International Energy Agency's executive director. OPEC agreed to cut output by 900,000 barrels a day starting Nov. 1. Terrorist attacks in the Middle East have led to speculation that shipments may be threatened.

Prices have also increased on concern that unrest in Saudi Arabia and Iraq will limit shipments from the two nations. Saudi Arabia is the biggest oil exporter and holds the world's largest proven oil reserves. Iraq, the Middle East's third-largest oil producer before the war to oust President Saddam Hussein, holds the second-biggest proven reserves.
