Oil prices plunged more than 8 per cent on Wednesday after the Democratic Party's sweeping victory in the United States midterm elections, as traders bet that the shift in power in Washington could hasten an end to the war with Iran. Brent crude, the global benchmark, settled 8.98 dollars, or 8.7 per cent, lower at 94.62 dollars a barrel, while US West Texas Intermediate crude fell 7.97 dollars, or 8.3 per cent, to settle at 88.12 dollars a barrel.
Both benchmarks closed at their lowest levels since August 31.
The fall was the market's verdict on an election that has changed the political calculations around the conflict. Democrats won control of both the House of Representatives and the Senate, handing President Donald Trump a heavy midterm defeat. Traders immediately began to reassess the prospects of a prolonged US-Israeli war against Iran, raising expectations that Washington could now pursue a diplomatic settlement rather than escalate the conflict.
The war has disrupted energy supplies from the Gulf and pushed up global oil prices for months, raising fuel costs for consumers and businesses around the world.
The immediate political trigger came from Vice President JD Vance, who publicly blamed the Iran war for the Republican Party's electoral defeat. "The reason we lost is the war," Vance said in a social media post on Wednesday, adding that President Trump himself had acknowledged the impact of the conflict. His remarks sent oil prices sharply lower, as traders read them as a sign that the administration would face growing pressure to find an exit from the war.
Trump also acknowledged that the war had contributed to the election setback. He had told the Financial Times on Tuesday that the United States had no immediate plans to strike Iran, and on Wednesday he accepted that the conflict had played a role in his party's defeat.
The election outcome matters for oil because it changes who controls the levers of American power. Democrats are set to take control of the House and the Senate when the new Congress convenes, and that could make it more difficult for Trump to secure political and financial support for an extended military campaign.
Congress has significant powers over government spending and military funding, and a Democratic-controlled legislature could use those powers, along with oversight and pressure through proposed war-related resolutions, to challenge the administration's approach to Iran. Senate Democratic leader Chuck Schumer has already indicated that his party intends to push for an end to the conflict.
Before the election, the market had been factoring in the risk of a wider conflict involving Iran, Israel and other countries in the Gulf. Any further escalation could threaten oil production, exports and shipments through the strategically important Strait of Hormuz, the narrow waterway that connects the Persian Gulf with international shipping routes and carries a large share of the world's seaborne oil.
The possibility of a diplomatic settlement has now prompted traders to unwind some of the geopolitical risk premium built into crude prices. That premium is the additional amount traders are willing to pay for oil because they fear that a conflict could disrupt supplies, and when the likelihood of escalation declines, the premium can fall even before actual oil shipments return to normal.
The market's reaction was reinforced by the scale of the Democratic victory. The Dow Jones Industrial Average surged 1,569 points, or 3 per cent, on Wednesday, posting its best post-midterm election day in 44 years and its biggest single-day gain since April 2025. Treasury yields fell, with the two-year yield dropping to a two-month low, and the VIX index, which measures expectations of volatility, sank almost 20 per cent.
"Traders are betting that the administration is going to quit this war because the midterms shellacking was bigger than anyone expected," said Bob McNally, president and founder of the Rapidan Energy Group.
But the market's optimism should not be mistaken for a peace deal. Washington and Tehran remain far from reaching an agreement, and the path to a settlement is complicated. Qatar has stepped up mediation efforts to prevent another round of military escalation following the US elections, and Iranian officials have indicated that communication through mediators is continuing.
A senior Iranian official told Reuters that the two sides were still far from a deal to end the war. There are also concerns about the terms of any potential settlement. An agreement that allows Iran to present the outcome as a victory, while leaving Trump politically weakened, could create fresh instability rather than end the conflict.
Iran's Supreme Leader, Ayatollah Mojtaba Khamenei, said in a written statement that US hostility would persist regardless of which party was in power.
The sharp fall in prices also needs to be viewed against the continuing disruption to global energy flows. Gulf exports of crude oil, condensate and refined petroleum products, excluding liquefied petroleum gas, averaged 17.1 million barrels per day in October, according to ship-tracking data from Vortexa cited by Reuters. That was lower than the 18.9 million barrels per day recorded in September, and it represented only around three-quarters of pre-war levels.
The Strait of Hormuz remains a critical factor in the global oil supply equation, and any disruption to tanker movements through it can affect the availability of crude, increase shipping and insurance costs, and push up prices across international markets. The United Arab Emirates is also considering the construction of a third oil pipeline to transport crude outside the Strait of Hormuz, according to a Bloomberg News report.
There was another development worth noting. US crude inventories unexpectedly declined last week, according to the Energy Information Administration. Crude stocks fell by 865,000 barrels to 409.8 million barrels in the week ended October 30, while analysts had expected inventories to increase by 877,000 barrels.
Normally, falling inventories can support oil prices because they indicate tighter supplies. But the sharp decline in crude prices suggests that expectations of a possible diplomatic settlement have outweighed this near-term supportive signal.
The slide continued into Thursday's Asian trading session. Brent for January settlement dropped 0.6 per cent to 94.04 dollars a barrel in Singapore after sinking 8.7 per cent in the previous session, while WTI for December delivery fell 1.1 per cent to 87.14 dollars a barrel after plunging 8.3 per cent on Wednesday. Moneyweb, citing Bloomberg, reported that Brent had suffered its biggest loss since May.
For India, the decline in international crude prices could offer significant relief. India is one of the world's largest oil importers, and it is particularly vulnerable to geopolitical disruptions in the Gulf because of its reliance on imported energy. The country imported 246.6 million tonnes of crude oil in the financial year 2025-26, with its crude oil import dependence reaching 88.7 per cent, according to data compiled from the Petroleum Planning and Analysis Cell.
According to estimates cited by The Indian Express, India imports around 1.8 billion to 2 billion barrels of crude oil annually, and every one-dollar increase in the price of a barrel can add up to 2 billion dollars to the country's annual oil import bill if sustained.
Higher crude prices increase India's import bill, put pressure on the rupee and can add to inflationary pressures through transportation, manufacturing and fuel costs. A sustained decline in crude prices could therefore improve India's external trade position, ease pressure on the current account and provide some relief to domestic industries. The rupee, which has been under pressure from foreign outflows, would also benefit from a lower oil bill.
However, a fall in international crude prices does not automatically translate into an immediate reduction in petrol and diesel prices at home. Domestic fuel prices also depend on the rupee-dollar exchange rate, refining and marketing costs, taxes and the pricing decisions of oil marketing companies.
What happens next will depend on whether the political opening created by the midterm result turns into real diplomacy. Traders will watch for signs that the new Congress intends to constrain the administration's military options, for progress in the mediation efforts led by Qatar, and for any change in the flow of oil through the Strait of Hormuz. If the war winds down, the risk premium could fall further and prices could settle lower.
If talks stall, or if the administration chooses escalation over negotiation, the premium could return just as quickly as it vanished. For now, the market has made its bet: the election has made peace more likely, and oil is priced accordingly.
