US gasoline futures rose above 3% on June 10 as fresh US self-defence strikes on Iran threatened a fragile ceasefire, the Strait of Hormuz remained under dual blockade, and SPR and crude draws offset a 3-million-barrel gasoline inventory build.

Key Highlights

  • US gasoline futures rose above 3% to $3.20 per gallon on June 10, reversing the prior session's decline.
  • US Central Command confirmed self-defence strikes on Iran after a US helicopter patrolling the Strait of Hormuz was downed.
  • The strikes threatened a fragile ceasefire and reduced the probability of a near-term Hormuz reopening.
  • The Strait of Hormuz remained under a dual blockade, severely constraining regional distillate exports.
  • A 3-million-barrel gasoline inventory build was offset by draws of roughly 8 million barrels each from private crude stocks and the SPR.

US gasoline futures rebounded on Wednesday, climbing above 3% to $3.20 per gallon after declining the previous session. The catalyst was a direct escalation in the US-Iran conflict. US Central Command announced self-defence strikes on Iranian targets, ordered by President Donald Trump following the downing of a US helicopter patrolling over the Strait of Hormuz.

The strikes immediately repriced the geopolitical risk premium that had briefly unwound on Tuesday, reversing the session's direction within hours. Trump subsequently warned Iran of further military consequences if negotiations failed to advance, reducing market confidence in a near-term diplomatic resolution.

The development placed the fragile ceasefire under renewed stress. The Strait of Hormuz, the focal point of the global supply disruption since late February, remains largely closed under a dual blockade involving both Iran and the United States. Regional distillate exports continue to be severely constrained, and any credible reopening timeline has been pushed further out by Wednesday's escalation.

Inventory Build Offset by Upstream Draws

On the supply side, US gasoline stockpiles rose by more than 3 million barrels in the final week of May, ending a 15-week run of consecutive declines. The build indicated refinery output had temporarily outpaced consumption at the retail level.

However, the improvement was offset upstream. Private crude inventories fell by roughly 8 million barrels over the same period, and the Strategic Petroleum Reserve recorded a draw of similar magnitude. With the SPR being drawn down repeatedly since the Hormuz disruption began, questions remain about the buffer's remaining depth heading into the summer demand peak.

Conclusion

Gasoline's rise above 3% on June 10 was driven by a direct military escalation over the Strait of Hormuz, which erased Tuesday's ceasefire-driven relief. The dual blockade remains intact, the SPR cushion is thinning, and the summer demand peak is approaching. The near-term supply outlook stays structurally tight until a verified diplomatic resolution materially changes conditions at the Strait.
