The oil market and the US SPR
Oil has been in the news as Saudi Arabia and Russia decided to extend production cuts for the rest of the year. There is another noteworthy government player when it comes to this critical commodity: the US Strategic Petroleum Reserve. Famously, President Biden ordered that oil be released from the SPR in 2022 to cushion consumers against the Ukraine war’s impact on gasoline prices.
This visualisation’s top pane tracks the year-on-year change in the price of Brent crude (in blue) against the year-on-year change in total US oil inventories (in green, on an inverted axis).
As the chart shows, historically, these variables are negatively correlated and the lines move in unison: when inventories go down, prices go up, and vice versa. (The post-pandemic demand snap-back is notable in late 2020: inventories plunged and prices rebounded.)
However, the 2022 SPR episode is clearly visible as a gap opened up between the two lines. The second “inventory breakdown” pane shows why this occurred: the SPR (in purple) kept releasing oil while commercial oil companies rebuilt inventory.
While that “commercial” segment has been rebuilding reserves lately, the SPR has not: it remains at its lowest level since 1983, with the Department of Energy waiting for a cheaper refill price.
