Oil Markets React to Hormuz Agreement, Though Sustained Relief Remains Uncertain
Oil prices fell sharply in the hours following a provisional US-Iran peace agreement that would reopen the Strait of Hormuz, raising cautious hopes for American consumers who have absorbed sharply higher fuel costs since hostilities began on 28 February.
The ceasefire deal, if it holds, could push the national average pump price below $3.75 per gallon by 4 July, according to Patrick DeHaan, Head Petroleum Analyst at GasBuddy — though he stressed that outcome depends on an optimistic timeline and stable implementation.
The Scale of the Price Shock
When the United States struck Iran on 28 February, the Strait of Hormuz — through which 20 per cent of global oil supply transits — became impassable for commercial shipping. The disruption sent oil prices surging and petrol prices with them.
By the first week of April, Americans were paying more than $4 per gallon for the first time since August 2022, up from $2.98 just two days before the conflict began. At the peak of the crisis in early May, analysts at JPMorgan Chase warned prices could breach $5 per gallon if the war continued.
In aggregate, US consumers have paid $59 billion more for fuel since 28 February compared with the equivalent period in 2025 — a significant demand-side drag on household budgets.
Fragility of the Agreement
DeHaan cautioned that the deal remains vulnerable. “The next few days will be key to see if the agreement sticks, and if traffic begins moving in the Strait,” he wrote on X. “One major slip up could impact greatly prices moving forward.”
He added that three consecutive weeks of price declines could quickly reverse: “With so many speedbumps in this situation, it may be foolish to think this problem is now completely over.”
Hurricane Season Adds Further Risk
Beyond geopolitical uncertainty, energy pricing service Opis flagged the approaching Atlantic hurricane season as an additional upside risk to fuel costs. “Gulf Coast refinery disruptions and fuel price volatility are just a sliver of the massive repercussions that can stem from hurricanes,” the firm noted.
Storms of sufficient magnitude can simultaneously impair refinery capacity and distort supply-demand balances for both gasoline and diesel, compounding any residual pressure from the Hormuz situation.
Political Fallout Mounts for Republicans
The prolonged cost-of-living squeeze has eroded public confidence in the administration’s economic management. 63 per cent of Americans disapprove of President Trump’s handling of the economy, according to an Economist/YouGov poll.
Trump has consistently framed the conflict in terms of nuclear non-proliferation rather than consumer affordability, leaving Republicans exposed ahead of November’s Congressional midterms, in which both the House and Senate majorities are at stake.
E.J. Antoni, Chief Economist at the Heritage Foundation, offered a blunt assessment in an interview with Steve Bannon’s War Room: “There’s no way to sugarcoat this. They’re up at the fastest rate since the Biden administration — so again, not good news here.”
