The delay removes traders and policymakers' most detailed read on US crude production, imports, exports and state-level output for several weeks at a minimum. That gap carries extra weight because the supply picture already looks tight, with the Strategic Petroleum Reserve at a 44-year low and shipping through the Strait of Hormuz still disrupted by the US-Iran conflict. The Weekly Petroleum Status Report continues to provide headline inventory and supply figures, so the market is not without data, but the absence of the fuller monthly breakdown adds uncertainty to output estimates at a time when precision matters. Analysts are likely to rely more heavily on private surveys and weekly data until the delayed report is released.

Washington's most detailed window into US oil output is going dark for weeks at a sensitive moment.

Summary:

• The US Energy Information Administration delayed the release of its Petroleum Supply Monthly report for June 2026, which had originally been scheduled for August 31, citing an operational issue.
• The agency now expects to publish the report sometime in September but has not provided a specific date.
• The problem is tied to how the EIA's back-end and public-facing systems interact.
• The report is the agency's most detailed source on US crude production, imports, exports and inventories, with breakdowns by state and region.
• The Weekly Petroleum Status Report remains on schedule, so some data continues to be available.
• The delay comes as the Strategic Petroleum Reserve sits at its lowest level in 44 years, while renewed US-Iran fighting continues to disrupt shipping through the Strait of Hormuz.
• The EIA has lost an estimated 30% to 40% of its staff since the start of President Trump's second term, through buyouts, terminations, return-to-office requirements and a hiring freeze.

The US Energy Information Administration has delayed publication of its Petroleum Supply Monthly report for June 2026, the agency's most detailed monthly account of domestic crude production, imports, exports and inventories. The report was scheduled for release on August 31 but will now appear sometime in September. The EIA did not give a firm date, saying only that it wants to validate the data before publishing.

The agency said the delay was caused by an operational issue affecting the interaction between its back-end and public-facing systems. On its own, that explanation might have drawn little attention. The timing, however, has attracted scrutiny because of how much depends on a clear picture of US supply at the moment.

The Strategic Petroleum Reserve is at its lowest level in 44 years, and renewed fighting between the United States and Iran has kept oil markets under pressure for months. The conflict has disrupted shipping through the Strait of Hormuz and prompted Washington to draw down its emergency stockpile in an effort to help smooth price swings.

The Petroleum Supply Monthly is also the government's only source for domestic output broken down by state and region. That information is not included in the EIA's Weekly Petroleum Status Report, which continues to be published on schedule. The weekly release keeps the immediate data flow from drying up entirely by covering inventories and broad supply metrics, but it does not replace the fuller monthly picture of how much crude producers are actually extracting across the country. Until the delayed report is released, that leaves a noticeable gap in official detail for anyone tracking how supply is evolving across producing basins and refining centers.

The delay also comes against the backdrop of a significantly reduced EIA workforce. The agency has lost an estimated 30% to 40% of its staff since the start of Trump's second term, through voluntary buyouts, the termination of probationary employees, new return-to-office requirements and a government-wide hiring freeze that has prevented it from replacing departures.

The agency has not said whether those staffing reductions played any direct role in the systems issue, but the loss of institutional capacity adds context to a report that traders and policymakers rely on for one of the clearest windows into the state of US oil production.
