Trump Says Iran War Oil Spike May Last Past Midterms

What changed

Based on AP Business reporting, President Donald Trump said oil prices are unlikely to fall before the Nov. 3 midterms as the U.S.-Israel war with Iran enters its seventh month. Brent crude rose more than 3% above $100 a barrel, U.S. crude stood near $96, and the national average for regular gasoline rose 7 cents overnight to $4.22 a gallon; diesel reached $5.94.

Why This Matters

This is no longer just an oil-market chart with an alarming number on it. It is a cost problem moving through businesses: trucks, warehouses, production lines and airline schedules. The Strait of Hormuz disruption matters because Gulf shipments have slowed dramatically, and roughly 20% of global petroleum passed through it before the conflict.

Our outlook (informed speculation): if the disruption persists, the next pressure point is likely to be operating budgets. Firms that cannot avoid diesel-heavy transport may try to pass costs into delivered prices, while airlines may protect margins with fewer seats, higher fares and added fees. That leaves customers paying more, or getting less choice, sometimes both.

How the effects could spread

Higher crude costs can lift wholesale fuel costs, then retail gasoline and diesel prices. The report already shows that movement in the 7-cent gasoline increase and the rise in diesel.

For freight-dependent businesses, higher diesel costs can squeeze margins or encourage surcharges and operational cuts over coming weeks. That can reach beyond the transport sector through the price of goods delivered to customers. The chain could weaken if Hormuz traffic improves, crude retreats, or competitive pressure makes suppliers absorb more of the increase.

Air travel is already feeling the fuel bill: carriers have cut flights while raising fares and fees. If jet fuel remains costly, capacity could stay tighter, making travel both pricier and less flexible.

Impact assessment

• Motorists: Immediate downside. Gasoline is already $4.22 a gallon on the reported national average.
• Freight-dependent businesses and their customers: Exposed over coming weeks. Record-high diesel raises transport and production costs, creating pressure to trim costs or raise delivered prices.
• Air carriers and travelers: Mixed for carriers, negative for travelers. Flight cuts and higher charges can support revenue per trip, but reduce available service and increase trip costs.
• Strategic petroleum reserve managers: Exposed over the longer term. The reserve fell below 300 million barrels in early August after a drawdown of more than 100 million barrels since the start of 2026, leaving less stated stock during an ongoing disruption.

Scenarios

Most likely: If Gulf oil flows remain materially constrained through the election period, fuel costs stay elevated for weeks to Nov. 3. Airlines could preserve reduced schedules, while diesel users seek savings or price increases. This is the baseline because the disruption is already affecting crude, gasoline, diesel and flight capacity.

Upside: If oil movement through the Strait of Hormuz improves and crude retreats, retail fuel pressure could ease over weeks to months. Airlines could stop cutting service or restore some flights, and transport-heavy businesses would face less reason to lift customer prices.

Downside: If attacks further disrupt tankers, shipping lanes or oil facilities, fuel costs could rise again within days or months. Airlines could make deeper cuts, while businesses that move goods by diesel may face a stronger incentive to add transport-related charges.

What to watch next

• Whether Brent stays near or above $100, and whether U.S. crude remains elevated.
• AAA’s national gasoline and diesel averages.
• Reports on oil traffic through the Strait of Hormuz.
• Airline flight reductions, fare increases and fee changes.
