Expectations of lower oil demand prompted funds selling because Hurricane Katrina has a negative effect in slowing down the U.S. economy.

Natural gas supplies have been severely disrupted in North America and the shortages took heating oil and crude prices higher.

The large 3.2 million barrel increase in (US) gasoline accelerated selling.

The market can't be too bearish, as they will also focus on refining capacity constraints in the Gulf of Mexico.

It is a very choppy market. The earlier hurricane threat did impact the U.S. oil market. Refinery runs were being reduced as workers got evacuated. Now Emily looks to be approaching.

There is nothing we can do about it when (U.S.) inventory data shows such a bearish numbers. The market will continue to test the bottom.

The market is led by natural gas now.
