Why The U.S. Gasoline Stock Build Was Not Surprising

Robert Boslego - INO.com Contributor - Energies

The Energy Information Administration (EIA) reported that gasoline stocks had “surprisingly surged despite heavy driving on the Memorial Day weekend.” But the 3.3 million barrel build was actually not that surprising, given the development of gasoline production capacity and the relative softness of gasoline demand.

Over the past four years, the U.S. refining industry expanded its gasoline production capacity in the United States by almost one million barrels per day. In 2013, production peaked at just below 9.5 million barrels per day. Last year, production peaked at 10.3 million. And this summer production could reach 10.5 million.

Gasoline Production

Gasoline demand growth has lagged. Peak demand in 2013 was just above 9.1 million. Last summer, demand peaked at 9.6 million, an increase of about one-half million.

But in the year-to-date, gasoline demand has been 2.9% lower than over the same weeks in 2016. Retail gasoline prices dropped to low levels in the first quarter of 2016, when crude oil prices were bottoming, and that created a surge in demand that was not repeated in 2017.

Gasoline Demand

Factors limiting demand growth are demographic. The percentage of older adults is rising. Retired adults do not commute daily to work. And they tend to stay home due to health and age reasons.

Young adults are driving less than previous generations. More are working from computers at home. They also use social media for connecting with friends and for entertainment. They are also moving to urban areas where gasoline use is lower.

Gasoline Production vs. Demand

As a result of the higher growth in production v. demand, a surplus has opened up. Production has been exceeding domestic demand.

U.S. refiners have therefore become net exporters of gasoline. But the difference between production and demand has exceeded net exports in many months, resulting in stock builds.

Gasoline Production Gap vs. Net Exports

Gasoline Surplus Capacity

This surplus capacity is likely to limit gasoline margins from expanding much even if there are drawdowns in gas stocks, as was the case in the first part of this year. Instead, gasoline stocks are unlikely to drop even during the peak demand months. In fact, they may rise because gasoline exports generally drop during the summer months.

U.S. Gasoline Imports
Note: Negative import numbers represent net exports

For the week ending June 2, 2017, gasoline production averaged 9.834 million barrels per day (mmbd), while demand averaged 9.317 mmbd. There were net imports of 215,000 b/d. Together, these figures supported the stock build.


The summer driving season has traditionally provided support for both gasoline and crude oil prices. But as was the case last summer, a surplus is more likely to undercut prices. This is another factor, together with rising crude production in the U.S., Nigeria, and Libya, that is likely to undermine oil prices in the weeks ahead. Do not be surprised to see additional gasoline stock builds during the driving season.
