Oil prices fell sharply on Wednesday, November 4, as the results of the U.S. midterm elections raised expectations that President Donald Trump could seek a diplomatic resolution to the war with Iran. Brent crude dropped below $100 per barrel for the first time since October 7, while U.S. crude settled below $90.
The decline followed months of rising energy costs linked to the conflict, which began on February 28 and disrupted shipping through the Strait of Hormuz. With gasoline and diesel prices weighing on households and businesses, the election results have brought renewed attention to the economic consequences of the war and Washington’s next steps.
Oil Markets Respond to Election Results and Signs of Diplomacy
According to CNBC, West Texas Intermediate crude fell 8.3% on Wednesday to settle at $88.12 per barrel, while Brent crude futures declined 8.7% to $94.62. The losses marked oil’s largest daily decline since April, following a steep retreat from recent highs.
Brent had traded as high as $118 per barrel on Friday before falling to around $94 by Wednesday. Oil futures dropped more than 14% during the week as senior American and Iranian officials indicated their willingness to consider a diplomatic settlement.
Political developments added to the market’s reaction. Democrats won control of both the House and Senate in Tuesday’s elections, increasing their ability to challenge the administration’s handling of the conflict.
Andy Lipow, president of Lipow Oil Associates, told CNBC that the election results were leading traders to believe Trump might now be more inclined to negotiate an agreement with Iran.
Uncertainty nevertheless remains. Rebecca Babin, senior energy trader at CIBC, warned that the sell-off could be excessive, while Bob McNally, president of Rapidan Energy, maintained that military escalation remained the more likely outcome.
Falling Fuel Prices Offer Potential Relief After Months of Increases
The decline in crude prices has brought attention back to gasoline costs, a major concern for American voters throughout the conflict.
According to NBC News, the national average gasoline price stood at $4.12 per gallon Wednesday morning, approximately 39% higher than before the United States and Israel launched the war against Iran on February 28.
An NBC News exit poll found that 59% of voters surveyed Tuesday were “very concerned” about gasoline and diesel prices. Trump acknowledged the political consequences during a Fox News appearance Tuesday night, saying voters had struggled with the short-term burden of higher fuel costs.
Diesel markets also recorded substantial losses. U.S. diesel futures fell nearly 7% by midday Wednesday, reaching their lowest level since late August.
The movement carries economic significance because diesel powers transportation networks that move groceries and other goods across the country. Higher transportation costs can affect retail prices, adding pressure to consumers already facing persistent inflation.
Patrick De Haan, an analyst at GasBuddy, told NBC News that falling oil prices could push the national gasoline average below $4 in the coming days.
Despite Wednesday’s decline, crude oil remained approximately 60% more expensive than at the beginning of 2026. The latest market reaction reflects shifting expectations surrounding the Iran conflict, even as its economic effects continue to be felt across the United States.
