The Price Impact of the Strategic Petroleum Reserve Release

Climate and Energy Economics Catherine Wolfram
To help address rising energy prices and mitigate a shortfall in the production of oil owing to
Russiaʼs war in Ukraine, President Biden in March of this year announced a historic release of
oil from the Strategic Petroleum Reserve (SPR). Following this action, the Department of
Energy is in the process of releasing 180 million barrels from the SPR over six months while
International Energy Administration (IEA) partners are releasing an additional 60 million
barrels. This blog presents analysis estimating the impact of this release on the price of retail
gas in the United States.
We use two approaches to calculate the impact of oil releases: the total change in stocks (a
change of 180 million to 240 million barrels) and the flow change in barrels (a change of 1.0
million to 1.33 million barrels per day). Both measures have merit. A 2017 study by Richard
Newell and Brian Prest argues that the change in stocks is a more appropriate measure, as it
includes market expectations, although their analysis models considerably smaller changes in
stocks over shorter time windows. Conversely, for a steady change in supply, it may be more
appropriate to model price changes based on flows.
We make several simplifying assumptions. First, we assume that the market clears on the
demand side – that is, there is zero elasticity of crude supply. Second, we assume any
transportation or issues of crude di erentiation are not large enough to have a meaningful
impact on prices. Third, we assume the market is driven by fundamentals, so responds to
changes in supply and demand, rather than speculation or other drivers. And we present these
estimates with the caveat that they are more accurate in the short run than over a longer
period.
There are additional factors that could also impact crude prices. First, some of the sales were
anticipated in advance. Second, private US crude stocks have increased by 17 million barrels
from a low on March 25 to the most recent value on July 15. The impact of these factors is
likely second order and not accounted for in our analysis.

We consider large and small options for the demand elasticities, or the responses of prices to
a change in supply. Specifically, we use 0.08 and 0.20 to bracket a range of possible short-run
demand elasticities but note that higher or lower values are possible.
It is unclear how much of these changes in oil prices were passed through to retail gasoline
and diesel prices. In general, we would expect one-for-one passthrough: a $1 per barrel
decrease in crude would lower the price of gasoline by $1 per barrel, equal to $0.024 per
gallon, since there are 42 gallons of gasoline per barrel. However, recently refining markets
have been very tight, and itʼs possible that a $1 change in crude oil would not lead to an equal
decline in the retail price of gasoline. The following table summarizes estimated impacts of
the SPR releases on gasoline prices, assuming full pass-through:

As shown in the table above, our analysis suggests that President Bidenʼs historic SPR
release, in coordination with IEA partners, lowered the price of gasoline by 17 cents to
42 cents per gallon, with an alternate approach suggesting a point estimate of 38 cents
per gallon. This decline in prices had meaningful benefits for American consumers and helped
to mitigate the impacts of rising gas prices on economywide inflation. Moving forward, the
Biden Administration is committed to further addressing concerns about rising energy prices.
