Despite the conflict and a partial closure of the strait, the volume of oil passing the U.S. blockade line has risen sharply. Tanker Trackers estimated that roughly 13 million barrels per day are now exiting the blockade line. Independent estimates noted in the reporting put the seven-day average around 13.5 million barrels per day, near a July peak that followed a short-lived ceasefire.
U.S. military role and safety measures
The shift to daytime passages has removed a throughput constraint imposed by night-only operations, allowing more ships per day to transit. U.S. Central Command has publicly highlighted the scale of escorted movements through Hormuz in recent months.
Global crude and refined fuels remain elevated compared with prewar levels, and global strategic reserves have drawn down further because current throughput remains below prewar volumes. The increase in flows has so far helped avoid catastrophic price spikes, but the costs of moving oil through the contested strait are high. Analysts cited in the report estimate the extra cost to deliver barrels through Hormuz can run $30–$40 or more per barrel, not counting the expense of U.S. military operations.
That elevated cost structure leaves exporters and shippers exposed if global prices fall or if Gulf producers try to move more volume despite the premium required for secure transit.
Political signaling and possible next steps
Trump framed Iran as weakened and said he's willing to make a deal but rejected Tehran's current terms. Reporting also referenced private comments attributed to Trump suggesting a potential resumption of bombing after midterm elections when domestic political sensitivity to higher gas prices might be lower. U.S. officials described confidence that economic pressure and the blockade are tightening the squeeze on Iran, while Tehran has continued attacks that complicate regional energy logistics.
Taken together, the operational changes permitting daytime escorts and the rise in oil outflows have eased some near-term market pressures. However, the high cost of secure transit, ongoing attacks, and the political decision by the U.S. to decline Tehran's ceasefire proposal sustain risk for further disruptions.
