Oil slips as Hormuz closure blocks 20% of supply, demand weighs

Crude slipped in early Asian trade Thursday as a closed Strait of Hormuz tightened supply while demand worries capped gains.

Oil edged lower in early Asian trade Thursday as the effective closure of the Strait of Hormuz — a waterway carrying about 20 percent of the world's crude — supported prices while demand concerns weighed on the market.

"Oil markets have been turbulent as the Strait of Hormuz remains effectively closed amid the ongoing Iran war," said Patrick De Haan, head of petroleum analysis at GasBuddy.

The national average gasoline price hit $4.04 a gallon Wednesday, a record for this time of year, according to GasBuddy. The average had never surpassed $4 a gallon on Aug. 12 or later in the calendar year, coming closest four years ago at $3.98.

With the Iran war showing no sign of resolution and a peace deal looking increasingly uncertain, supply risks remain elevated. If the closure persists, prices could push higher; if a deal emerges, the supply overhang could unwind quickly.

The mixed signals reflect a market torn between a tightening supply picture and softening demand. On the supply side, the Strait of Hormuz closure has removed a critical artery for global crude flows. The waterway typically sees roughly 20 percent of the world's oil pass through each day during peacetime, according to GasBuddy. Its effective closure has kept a floor under prices even as traders weigh the risk of a prolonged conflict.

On the demand side, energy prices fell last month, as reflected in yesterday's consumer price index report for July, which showed the annual inflation rate ticking down to 3.4 percent from 3.5 percent in June. That remains above the Federal Reserve's goal of 2 percent inflation. The cooling energy component helped ease headline inflation even as gasoline prices at the pump climbed to records.

The last time the national average approached $4 a gallon this late in the year was four years ago, when it hit $3.98 on Aug. 12. That comparison shows how unusual the current price level is for this point in the calendar, when seasonal demand typically begins to fade after the summer driving peak.

For consumers, the record pump prices come at a politically sensitive moment. The $4.04 national average translates into higher costs across the economy, feeding into the inflation readings that shape Federal Reserve policy. If the Hormuz closure drags into the autumn, the supply shock could keep gasoline prices elevated through the midterm election season, adding to pressure on the administration to resolve the conflict.

The cross-asset transmission runs both ways. Higher crude feeds directly into the gasoline and diesel components of the consumer price index, complicating the Fed's path back to its 2 percent target. At the same time, a stronger dollar — supported by the relatively higher U.S. rate outlook — tends to weigh on dollar-denominated crude, partially offsetting the geopolitical premium. That tension explains why the market has struggled to find direction despite the supply disruption.

The supply picture remains the dominant driver. With the Hormuz closure cutting off a major share of global crude flows, any further escalation in the conflict would tighten the market further. At the same time, the demand outlook has softened as high pump prices begin to curb consumption, a dynamic that historically emerges once gasoline crosses the $4 threshold. The tug-of-war between these forces has left crude rangebound, with traders reluctant to commit in either direction until the geopolitical picture clarifies.

Traders are watching for any sign of a diplomatic breakthrough. The prospect of a peace deal has looked increasingly uncertain, according to GasBuddy, leaving the market to price in a prolonged disruption. Should negotiations collapse entirely, analysts expect crude to test fresh highs as the supply shortfall deepens. Conversely, a rapid resolution would likely trigger a sharp unwind of the war premium, sending prices lower as blocked tankers resume normal flows.
