Crude oil volumes passing through the Strait of Hormuz have recovered to levels seen before the outbreak of the Iran war, yet flows of refined fuel remain restricted, sources indicated on 1 October 2026.
The report said a seven-day average of 13.5 million barrels per day of crude was transiting the waterway as of Monday, a figure that matches the prewar baseline for shipments through Hormuz. That recovery has been driven in large part by a combination of U.S. military escorts and the redirection of pipeline flows, the source added.
The return of crude to near-normal throughput marks a notable shift from the sharp disruptions recorded after hostilities began. The seven-day average metric cited in the report was presented as the principal indicator that crude exports by volume have essentially normalised compared with pre-conflict levels.
Despite the recovery in crude shipments, sources noted that deliveries of refined fuels remain constrained. The divergence between crude and fuel movements is evident in the contrast between restored crude averages and ongoing limits on refined product exports and shipments.
Security measures and maritime escorts
U.S. military escorts were identified in the report as a significant factor enabling the renewed crude transit. Those escorts have been credited with providing the security environment necessary for tankers to resume routine passage through the Strait of Hormuz, according to the source.
Pipelines redirected flows away from some routes, easing pressure on maritime chokepoints and contributing further to the observed increase in crude volumes. The combination of military protection at sea and altered land-based flows was presented as decisive in bringing volumes back to prewar norms.
Fuel shipments remain constrained
While crude exports have rebounded, the supply of finished fuels continues to be limited, the report said. Sources described fuel shipments as remaining constrained, a condition that persists even as crude oil volumes return to earlier levels.
The report did not provide additional detail in the supplied notes on the specific causes for the constrained fuel shipments or on the geographic distribution of those shortages. The contrast between crude and refined product movements was a central theme of the coverage.
Market watchers and shipping interests will view the re-established crude flows as easing pressure on global seaborne oil logistics, but the continued constraints on fuel shipments underscore a separate set of logistics and processing challenges that have not yet been resolved, the source implied.
The recovery to a seven-day average of 13.5 million barrels per day suggests that, for crude at least, tanker operators and charterers are once again able to move volumes through Hormuz at a scale comparable with the prewar era. The report framed that figure as meeting the prewar baseline for shipments through the strait.
The picture presented by reports on 1 October 2026 therefore combines an operational improvement for crude exports with an ongoing shortfall in refined fuel movements. Shipping companies, energy traders and regional authorities will likely monitor how long the gap between crude throughput and fuel shipments persists and whether additional measures are taken to alleviate constraints on refined products.
For now the headline outcome remains clear: crude exports transiting the Strait of Hormuz have, according to the report, essentially returned to prewar levels, while fuel shipments continue to lag behind.
