AAA: Gas Prices Tumble

National average gasoline prices dipped to $3.48 at the start of August. However, AAA noted rising tensions in the Middle East could push oil prices higher.

Gas demand slid from 9.45 million b/d to 9.25 in the last week of July and total domestic gasoline stocks fell from 227.4 to 223.8 million barrels. Gasoline production decreased last in the final week of July, averaging 10.0 million barrels per day. AAA said lower gasoline demand with higher oil costs may lead to flat or slowly rising pump prices dipping, but that depends on Atlantic storm development.

Oil Market Considerations

At the start of August, AAA reported West Texas Intermediate (WTI) rose dramatically by $3.18  to $77.91 a barrel. EIA reported crude oil inventories decreased by 3.4 million barrels from the previous week.

At 433 million barrels, U.S. crude oil inventories are about 4% below the five-year average for this time of year.
