Strait of Hormuz Reopened, But Grocery Prices Will Take Months to Follow Oil Lower

The U.S.-Iran conflict that escalated in February 2026 effectively shut down the Strait of Hormuz, the chokepoint through which roughly 20% of the world's oil supply moves daily. Iran mined the strait and fired on vessels attempting passage without permission. The U.S. responded with a blockade on Iranian ships. At the peak, as many as 112 tankers were stranded in or near the waterway, along with hundreds of ships carrying fertilizer and other commodities, according to The Food Institute.

Brent crude spiked above $120 per barrel. West Texas Intermediate surged as much as 55% from pre-conflict levels. Fertilizer prices jumped approximately 40% as urea and phosphate shipments — two of the most widely used agricultural inputs on earth — ground to a halt, according to Crypto Briefing.

The ceasefire, reached between roughly June 15 and 19, triggered an immediate 5% single-day drop in oil prices. As of early this week, WTI was trading around $80.75 per barrel and Brent at $83.17, the lowest levels since March 5. From the March highs, crude has now fallen roughly 33%, according to The Food Institute and Crypto Briefing.

Oil prices are the headline number, but fertilizer is where the food chain actually feels the pressure. The fertilizer story is more complicated than the oil story.

By late June, at least 16 vessels had resumed fertilizer shipments through the strait. China also eased its export restrictions on urea, adding downside pressure to input costs, according to Crypto Briefing.

But Marty Bauer, director of partnerships and ecommerce at Omnisend, told The Food Institute that the strait blockage was only part of the problem. "Drone strikes damaged gas infrastructure that's essential for fertilizer production," Bauer said. "It will take months or even years to fix them."

The World Food Program, cited by Bauer, has been direct: fertilizer shortages will affect crop yields for months to come regardless of whether ships are moving again.

Farmers who purchased inputs at the 40% markup during the conflict are locked into those costs for the current growing season. That expense doesn't retroactively get cheaper because a ceasefire was signed, as Crypto Briefing noted. The full normalization of the fertilizer market is expected to lag into 2027.

Barry Bradley, head of supply chain at Crisp, told The Food Institute the reopening is "very positive news for F&B supply chains" and that loosening input supplies should "help alleviate the pressure on costs and, therefore, impact consumer demand." He added a clear caveat: the reopening won't be immediate, details were still being negotiated as of the ceasefire announcement, and shipping insurance rates remain a critical variable.

Colin Houchins, director of sales at Tosca, was blunter. Prices are unlikely to drop significantly in the near future because they depend on broader economic conditions, and whatever savings lower energy costs produce will take time to move through the production process, he told The Food Institute.

At the gas pump, the early signal is real but modest. The national average for regular gasoline was $4.07 per gallon as of this week, down 9 cents from the prior week. Diesel — which matters more for food trucking — was $5.197 per gallon, down from $5.318 a week ago and $5.662 a month ago, according to AAA data cited by The Food Institute. The U.S. Energy Information Administration puts crude oil at roughly 47% of the pump price, so the math on further savings is there if prices hold.

Skeptics of the ceasefire's durability have a reasonable point. The World Bank Group's April 2026 Commodity Markets Outlook, published by economists John Baffes, Dawit Mekonnen, and Kaltrina Temaj, projects a 2.5% increase in the global food commodity price index for 2026, but notes that risks are "firmly tilted to the upside." El Niño conditions are expected to intensify to moderate or strong levels during the Northern Hemisphere fall, with forecasters estimating nearly a two-thirds probability of very strong intensity by November or December, according to the U.S. National Oceanic and Atmospheric Administration as cited by the World Bank.

El Niño typically brings drought to Southeast Asia and drier conditions across parts of Australia, northern Brazil, southern Africa, and South Asia — all key producing regions for grains and oilseeds. If the ceasefire holds but El Niño hits hard, the cost relief from reopening the strait could be offset by crop shortfalls across multiple belts simultaneously.

The World Bank's baseline assumes Middle East supply disruptions ease in the third quarter of 2026. The ceasefire is broadly consistent with that assumption. But the strait's physical infrastructure, especially gas processing facilities hit by drone strikes, will need independent verification before shipping insurance rates and routing decisions fully normalize.

The Food and Agriculture Organization's global food price index showed vegetable oils alone jumping 6% in a single reporting period during the disruption, according to Crypto Briefing, and the overall index masked sharper spikes in regions dependent on imported food and energy. Those more fragile markets — sub-Saharan Africa, parts of South Asia — are the ones least able to absorb a prolonged lag between oil-price relief and grocery-aisle reality.

The concrete unresolved question as of July 3, 2026: how fast can Iranian gas infrastructure, damaged by drone strikes and essential for urea production, actually be repaired? That timeline, not the ceasefire itself, is the variable that will determine whether fertilizer costs normalize in one growing season or two.
