The claim is not supported by the available evidence. The latest weekly figures show the Strategic Petroleum Reserve decreasing by 6.1 million barrels to 298.7 million barrels, rather than dropping by 5.3 million barrels to 293.4 million barrels.

Key Evidence
CNBC stated that the SPR declined by 6.1 million barrels to 298.7 million barrels in the August 2026 report.
Energy Factbook, using weekly data from the EIA released on August 12, reported the same totals for the week ending August 7.
The Hill, Quartz, OPIS, and 24/7 Wall St.
Also supported the reserve's fall below 300 million barrels, though their publication dates and phrasing vary.
What the Evidence Shows
The latest evidence covers the week that ended on August 7, 2026, with the figures published on August 10 or August 12. CNBC, Energy Factbook, The Hill, Quartz, and other outlets report that the SPR held 298.7 million barrels after losing 6.1 million barrels during the week.
These figures contradict both elements of the claim. The weekly reduction was 6.1 million barrels, not 5.3 million, and the reserve total was 298.7 million barrels, not 293.4 million. The reports also consistently state that the inventory dropped below 300 million barrels for the first time since January 1983.
Earlier Reuters coverage cited other weekly changes, including a decline of about 5.5 million barrels on June 29 and roughly 3 million barrels on July 13. Neither figure matches the claimed inventory or reporting period. A July 28 CNBC article also predates the newest data and placed the reserve near 308 million barrels after a weekly decrease of 3.7 million barrels.
The supplied sources do not indicate whether a later report, issued after August 7, revised the inventory to 293.4 million barrels. Based on the latest weekly information available in the evidence, however, the claim is contradicted.
