Department of Energy figures show the Strategic Petroleum Reserve declined by 6.2 million barrels for the week ended July 3, leaving the SPR at 319.5 million barrels - its lowest level since April 1983. The drawdown is part of a planned 172 million-barrel release intended to alleviate global supply shortages tied to the Iran war and to ease fuel prices. Combined U.S. oil inventories, including commercial stocks plus the SPR, have fallen by 120.71 million barrels since the conflict began in late February, with total inventories at 734 million barrels as of June 26 - the lowest since 1984.

Key Points

  • The Strategic Petroleum Reserve fell by 6.2 million barrels in the week ended July 3, totaling 319.5 million barrels - the lowest since April 1983.
  • The decrease is part of a planned U.S. release of 172 million barrels aimed at addressing global oil supply shortages tied to the Iran war and at reducing fuel prices.
  • Combined U.S. oil inventories (commercial stocks plus the SPR) have declined by 120.71 million barrels since the war began in late February, standing at 734 million barrels as of June 26 - the lowest since 1984.

Overview

New Department of Energy data released Monday show the United States Strategic Petroleum Reserve (SPR) decreased by 6.2 million barrels in the week that ended July 3, bringing total SPR holdings to 319.5 million barrels. That level is reported as the lowest recorded since April 1983.

Planned releases and stated aims

The decline in the SPR is part of a broader U.S. initiative to release 172 million barrels from the reserve. According to the information provided with the DOE figures, the stated purpose of that release is to address shortages in global oil supplies following the Iran war and to reduce fuel prices.

Combined inventories

When commercial crude stocks are combined with the Strategic Petroleum Reserve, total U.S. oil inventories have fallen by 120.71 million barrels since the war began in late February. The combined inventory level was recorded at 734 million barrels as of June 26, which the DOE data identifies as the lowest such total since 1984.

Context and limitations

The numbers reported here come directly from Department of Energy data released on Monday. They reflect weekly changes in the SPR and aggregated inventory figures as of the specified dates. The data include a specific plan to release 172 million barrels from the reserve; no additional figures, timelines, or future projections beyond what is stated in the DOE release are provided in the source material.


Brief note

The figures in this report are drawn from the Department of Energy release and are presented without additional interpretation beyond the DOE's statements about the intended purposes of the planned SPR releases.

Risks

  • Continued reductions in SPR and total inventories could influence energy markets and fuel prices; the article does not provide future inventory projections.
  • The planned release of 172 million barrels is intended to address shortages linked to the Iran war, but the data do not specify the timing or distribution details of those releases.
  • The weekly inventory figures and combined totals are sensitive to ongoing developments; the report contains only the stated figures up to the dates provided and does not include subsequent changes.
