Gas demand plummets to lowest level in nearly 12 weeks

(September 15, 2020) The latest Energy Information Administration (EIA) report measures gasoline demand at 8.3 million billion barrels a day, which is the lowest level since mid-June. As demand dropped for a second week, so did gasoline supply levels — down nearly 3 million bbl to 231 million barrels. While consistently decreasing week-over-week, supplies also sit at a 3 million barrels year-over-year surplus.

“Typically lower supply levels translate into higher pump prices. However, even with consistent declines in gasoline stocks, that’s just not the case right now,” said Jeanette Casselano, AAA spokesperson. “Despite the steady supply dip, continued low levels of demand helped push the national gas price cheaper on the week.”

Today’s national gas price average is $2.19, which is three cents less than last week, two cents more than a month ago, but 37 cents cheaper than mid-September last year. On the week, all states saw gas prices decrease or stabilize at the pump. States with the largest declines are paying a nickel to a dime less, but the majority of state averages pushed cheaper by a few pennies since last Monday.

Mid-September is typically a point in the year that ushers in cheaper gas prices due to the switchover at gas stations from summer-blend to winter-blend, which is cheaper to produce. The difference between the two blends comes down to Reid Vapor Pressure (RVP), which is a measure of how easily the fuel evaporates at a given temperature. The higher — or more volatile — the RVP, the more able it is to evaporate at low temperatures. Winter-blend has a higher RVP which allows the fuel to evaporate at low temperatures for the engine to operate properly, especially when the engine is cold. If the RVP is too low on a frigid day, the vehicle will be hard to start and once started, will run rough.

“Motorists will see some cost savings at the pump with the switchover to winter-blend, but the price difference will be less than other years given how cheap prices have been this year already,” added Casselano. “However, hurricanes can always change any forecast for savings.”

The National Hurricane Center is currently tracking a number of tropical storms and depressions. Tropical Storm Sally is expected to produce life-threatening storm surge and hurricane-force winds for the northern Gulf Coast starting later today. Sally has already forced at least one refinery shutdown in Louisiana at Phillips 66. Others are watching the storm to determine any operational decisions (see more details in Oil Market Dynamics section). Any pump price impacts will likely be contained to the region and not have a national impact.
