With midterm elections approaching, Trump has taken two actions.

Currently, there are two U.S. aircraft carriers in the Middle East—the USS Bush and the USS Washington. Once the USS Roosevelt arrives, and if the USS Washington remains, that will bring the total to three carriers. The last time such a large-scale naval deployment occurred was in April this year, shortly after a round of U.S.-Iran hostilities ended with a fragile ceasefire agreement. Four months later, three carriers have returned—this time accompanied by an amphibious ready group and roughly 2,000 Marines. Trump appears determined—but whether or not military action will actually occur depends not only on carrier deployments, but also on another move he’s made: pressuring Europe to either release their diesel reserves or face a U.S. diesel export ban. Coinciding with the U.S. troop buildup, the G7 announced the release of petroleum reserves. On October 2, French President Macron convened a video summit of G7 leaders and announced the immediate release of 100 million barrels of strategic petroleum reserves over four months—with diesel releases concentrated in the first 20 days. Why release oil? Because Brent crude has surged to $102 per barrel. In the Strait of Hormuz, oil tankers are being struck one after another by ‘unidentified projectiles’; on October 1, yet another tanker caught fire while transiting the strait—making at least three tanker attacks within the past week. Even more troubling is the diesel shortage. According to a JPMorgan report, the diesel supply deficit is far greater than that for crude oil. U.S. diesel prices have hit an all-time high—$6.40 per gallon. What we’re seeing now, therefore, are two parallel tracks: one involving military escalation—deploying a third carrier strike group and nearly 10,000 troops to the Middle East, preparing for intensified operations after the midterms—and the other involving market intervention—G7 countries jointly injecting 100 million barrels of oil into global markets to suppress prices. One track prepares for war; the other exhausts every possible measure to stabilize oil prices. Earlier, Trump rejected an Iranian proposal to reopen the Strait of Hormuz within seven days. Iranian Foreign Minister Hossein Amir-Abdollahian stated the proposal contained no new conditions—only a call for the U.S. to fulfill commitments already agreed upon in the June memorandum of understanding. Trump responded, “That’s not good enough.” That raises an intriguing question: If Iran offers a plan to reopen the strait, and the U.S. rejects it—then proceeds to deploy additional forces—what is the relationship between military buildup and oil prices? More warships in the Middle East make tankers even more reluctant to sail through the strait, pushing oil prices higher still. Releasing crude reserves may suppress prices temporarily—but not indefinitely. Once those 100 million barrels are injected into the market, the carriers remain stationed there, and the strait stays closed. On the same day, the United Nations released a report warning that, if the Middle East crisis continues along its current trajectory, up to 22 million people worldwide could face food insecurity by year-end—including 11.7 million women. A blocked Strait of Hormuz affects far more than just oil prices: it disrupts grain shipments, fertilizer supplies, and transportation costs—triggering cascading effects across global markets. These ripple effects would significantly raise the political and economic cost of any war Trump might launch.

Reports say the Trump administration is considering a 90-day diesel export ban, but the White House later denied it, and the U.S. Energy Secretary publicly opposed it.

The Trump administration is evaluating a diesel export ban to curb soaring fuel prices—but internal policy disagreements have become public. Energy Secretary Chris Wright explicitly stated the ban would be ineffective and could drive up gasoline and aviation fuel prices, directly contradicting Trump’s position. According to a Politico report on Wednesday—citing five anonymous sources—the Trump administration is preparing a 90-day diesel export ban aimed at lowering persistently high energy prices ahead of the November congressional midterm elections, amid mounting political pressure on Republicans. Following the Politico report, U.S. diesel futures plunged sharply—falling more than 7% at one point. Meanwhile, European diesel futures surged. But shortly afterward, Reuters quoted a White House official who posted on X (formerly Twitter) stating that Politico’s report about the administration preparing a 90-day diesel export ban was inaccurate. U.S. diesel futures rebounded somewhat but failed to fully recover the losses triggered by the Politico report. Nonetheless, the administration’s open internal rift has cast significant uncertainty over the policy’s future. Energy Secretary Chris Wright, speaking the same day at an Economist event in New York, bluntly declared that banning diesel exports would “definitely not work,” warning it would force refineries to cut production—thereby raising gasoline and jet fuel prices. The Department of Energy subsequently issued a statement asserting that Wright “fully aligns with the President” and that both are “jointly exploring all viable options to lower energy prices”—an apparent attempt to downplay the disagreement. Soaring diesel prices and mounting midterm election pressure U.S. diesel prices are at record highs. According to data from the American Automobile Association (AAA), the national average diesel price stood at $6.52 per gallon on Wednesday—up 76% year-on-year. This surge stems from the U.S.-Iran conflict and the ongoing war in Ukraine, which continue to tighten global diesel supply. Skyrocketing fuel costs have drawn sharp complaints from farmers and other diesel-dependent users—and have evolved into a core political liability for Republicans. U.S. Agriculture Secretary Brooke Rollins has raised the issue of high diesel prices directly with the President, and Republican lawmakers representing highly competitive districts have likewise ramped up pressure on the administration to act.
