US gasoline futures are up more than 3% on Monday, rebounding from a six-week low as Iran suspended diplomatic exchanges with Washington and geopolitical risk premiums returned to energy markets. A 15-week consecutive draw on US gasoline inventories adds a tightening Supply narrative to the rally.

Key Highlights

  • US gasoline futures are trading up 3.44% at $3.1388 per gallon on Monday, recovering from a six-week low of $3.03 reached on May 29.
  • Iran's suspension of diplomatic exchanges with Washington, citing Israeli military operations in Lebanon, has reintroduced a geopolitical risk premium across energy markets.
  • US gasoline inventories recorded a 15th consecutive weekly decline in May, reflecting sustained high refinery run rates and a product mix shift toward diesel and jet fuel.
  • Refineries are drawing on crude from strategic reserves to maintain throughput, adding a structural dimension to the supply tightness narrative.
  • The Strait of Hormuz, through which roughly 20% of global oil traffic moves, remains a focal point for supply disruption risk.

Geopolitical Catalyst Drives the Rebound

US gasoline futures are climbing sharply on Monday, reversing a slide that had pushed prices to their lowest level in six weeks. The primary catalyst is geopolitical rather than domestic. Iran's semi-official Tasnim news agency reported that Tehran's negotiating team is suspending the exchange of documents with Washington through intermediaries, a development that has reignited concerns about the durability of the ceasefire framework between the two countries.

Iranian Foreign Ministry spokesperson Esmail Baghaei acknowledged continued engagement with the US while characterising it as proceeding under conditions of distrust, a formulation that offered little reassurance to energy traders already sensitive to any deterioration in the diplomatic channel. President Donald Trump struck a more optimistic tone on Truth Social, asserting that discussions with Tehran would resolve favourably, though his comments did little to offset the immediate market reaction.

Renewed military exchanges near the Strait of Hormuz over the weekend have kept supply disruption risk firmly in view. Any sustained interference with traffic through the strait carries direct consequences for global crude flows, which in turn affects refinery feedstock costs and, ultimately, refined product prices at the wholesale and retail level.

Inventory Tightness Adds a Structural Dimension

Beyond the geopolitical impulse, the gasoline rally is drawing support from a supply picture that has been tightening for several months. US gasoline inventories declined for a 15th consecutive week through May, an unusually prolonged draw that reflects the combined effect of elevated refinery throughput and a deliberate shift in product mix.

Refiners have been allocating a greater share of processing capacity toward diesel and jet fuel production, responding to supply concerns in those markets. That shift, while rational from a Margin perspective, has reduced the incremental Volume of gasoline entering storage at a time when seasonal Demand is building toward its summer peak.

To sustain high run rates, refineries have drawn on crude from strategic reserves, a pattern that underscores the extent to which domestic supply chains are operating under pressure. The sustainability of this approach over an extended period carries its own risks, particularly if geopolitical disruptions tighten crude availability further.

Price Trajectory and the Risk Balance

The convergence of a geopolitical premium and a structurally tighter inventory position creates a more constructive near-term backdrop for gasoline prices than the six-week low reached at the end of May would suggest. Whether the current move holds will depend largely on the trajectory of Iran-US negotiations and whether the ceasefire framework shows signs of stabilising or deteriorating further.

On the demand side, the onset of the US summer driving season provides a seasonal tailwind that typically supports consumption through August. That dynamic, layered over the inventory draw and the Middle East supply risk, positions gasoline among the more reactive commodities to any further escalation in the region.
