Trump Issues Tuesday Deadline to Iran Over Strait of Hormuz Amid Rising Fuel Prices

Few places on the planet matter more to the global economy than the Strait of Hormuz, a critical waterway now at the center of escalating tensions between the United States and Iran.

President Donald Trump has given Iran until Tuesday to allow all vessels through the key maritime passage or face military strikes on critical infrastructure, as fuel costs climb sharply across the United States and global markets.

In a strongly worded post on Truth Social on Sunday, Trump threatened action against Iran’s power plants and bridges if the strait isn’t reopened. “Tuesday will be Power Plant Day, and Bridge Day, all wrapped up in one, in Iran,” Trump wrote, setting a specific deadline of 8:00 p.m. Eastern Time on Tuesday. The president also announced plans to hold a press conference at the White House on Monday alongside military officials.

The Strait of Hormuz, measuring just 21 miles wide at its narrowest point, serves as a vital maritime corridor between Iran, Oman and the United Arab Emirates. Energy analysts consider it one of the world’s most important choke points for global commerce, with approximately 20 million barrels of oil passing through daily — alongside roughly one-fifth of global liquefied natural gas supplies.

Beyond crude oil, the strait is crucial for refined petroleum products. The Middle East exports about 1.1 million barrels per day of jet fuel through this passage, representing 15% to 17% of global consumption, according to Jaime Brito, executive director of refining and oil products at OPIS.

The economic impact of the standoff is already rippling through global energy markets and hitting American consumers directly at the pump. As of April 5, the national average for regular gasoline reached $4.11 per gallon according to AAA data, representing an 86-cent increase from just a month earlier.

Regional price disparities remain significant across the United States. West Coast drivers face the steepest costs, with California reaching $5.92 per gallon and Washington state at $5.37. On the East Coast, prices have climbed above $4 in several areas, including $4.27 in Washington, D.C., and $4.06 in New York. Midwestern states are seeing mid-$3 range prices, with Illinois standing out at $4.29 per gallon. Southern states generally remain cheaper overall, though prices are rising rapidly there as well.

Diesel fuel, critical to freight transportation and shipping, has seen even more dramatic increases. The national average has surged to $5.61 per gallon, up approximately $1.45 over the past month. The situation has become particularly severe in San Francisco, which recently became the first U.S. city to record diesel prices exceeding $8 per gallon — an unprecedented milestone according to GasBuddy tracking data.

The aviation sector is experiencing perhaps the most acute effects of the crisis. Jet fuel prices in the United States have more than doubled in a matter of weeks, jumping from approximately $2.11 per gallon in January to $4.88 by April 2, according to the Argus U.S. Jet Fuel Index, which tracks prices across major U.S. hubs.

Industry analysts note that jet fuel is especially vulnerable to supply disruptions due to thin inventories, specialized storage requirements, and limited spot trading. Airlines have warned that current inventories could be depleted within weeks without resolution, raising serious concerns about potential airfare increases and flight cancellations.

The Strait of Hormuz has long been a strategic flashpoint in Middle East tensions, but the current situation represents one of the most direct confrontations in years between the United States and Iran over this vital shipping lane. With Tuesday’s deadline approaching, global energy markets remain on edge as traders, shipping companies, and consumers brace for potential further disruption to this critical supply route.
