When functional, our refineries meet the demand in the US for gas and oil. Also, our usage is meeting forecasts. Up until this week, there was no refined gas shortage.
The increase in prices (up to now) has nothing to do with US consumption or supply. The increase in gas price is do to the following factors:
1. China's increased demand for crude
2. India's increased demand for crude
3. Instability in the middle east
4. Political instability in South America
That was until this week. Now, the hurricane has affected up to 30% of US production. Eight refineries have closed. Several others will have to close unless they get their normal supply of crude. That is where the reserves come in. The President will "loan" the crude to those refineries that are still open but don't have the necessary supply of crude.
We need to get the rigs in the gulf up and pumping crude to the refineries quickly. If we don't we will face supply shortages. That will mean an increase in price.
