For the second week in a row, the Tennessee gas price average saw a double-digit increase week-over-week. Since last Monday, gas prices across Tennessee have risen 10 cents, on average. The Tennessee Gas Price average is now $3.12 which is 22 cents more expensive than one month ago and $1.18 more than one year ago.  In Tullahoma prices Monday saw an average of $3.09 per gallon as the last stations that held doggedly to sub-$3 prices for 87 octane gave way to price increase.

"Compared to the price of gas a year ago, it now costs consumers about $17 more to fill up their vehicles," said Megan Cooper, AAA - The Auto Club Group. "Unfortunately, it doesn't look like drivers will be finding relief at the pump any time soon. Global supply concerns continue to keep upward pressure on the price of crude oil, which is now closing daily above $80 per barrel."

National gas prices

The national average for a gallon of gasoline rose a nickel over the past week to hit $3.32. The primary driver of this surge remains the cost of crude oil, which is now closing daily above $80 a barrel. In August, the price of crude was in the low $60s per barrel.

According to new data from the Energy Information Administration (EIA), last week's total domestic gasoline supply fell by 2 million bbl to 223.1 million bbl. Gasoline demand also fell from 9.43 million b/d to 9.19 million b/d, but the agency calculates it is still some 610,000 b/d above last year. Typically, softening demand should result in some easing of pump prices, but the higher cost for crude is blocking this. With oil prices remaining elevated, pump prices will follow suit because the cost of crude oil accounts for more than half of the price of each gallon of gas.

Forecasts from the International Energy Agency for more robust oil demand, especially heating oil this winter, are also keeping crude oil prices elevated. Today's national average of $3.32 is 13 cents more than a month ago, $1.16 more than a year ago, and 67 cents more than in 2019.

National oil dynamics

At the close of Friday’s formal trading session, WTI increased by 97 cents to settle at $82.28. Crude prices increased last week despite the EIA reporting that total domestic crude inventories increased by 6.1 million bbl to 427 million bbl last week. The current storage level is nearly 13 percent lower than the level at this same time last year. Given supply concerns, the market continues to bolster prices higher because of tight supply. Prices could climb further this week if EIA’s next report shows a decline in stocks.
