Oil prices fell sharply on Wednesday, November 4, 2026, the day after the US midterm elections. Brent crude dropped below the symbolic $100 mark, buoyed by hopes for a military de-escalation in the Middle East following the Democrats' victory in Congress. This decline could help ease fuel prices, although significant geopolitical uncertainties remain.
The oil market experienced another session of high volatility. On Wednesday, November 4, the price of Brent crude, the international benchmark, fell below $100 a barrel for the first time in nearly a month. At midday in the United States, it was down more than 9%, trading around $94, according to market data reported by the Associated Press . West Texas Intermediate (WTI) crude was also trending downward. This correction comes after several weeks of high prices, fueled by military tensions between the United States, Israel, and Iran.
The decline in oil prices accelerated after the results of the US midterm elections on November 3rd. Democrats won control of both houses of Congress, ending the Republican Party 's parliamentary dominance . For investors, this new balance of power could limit some of Donald Trump's initiatives and strengthen political pressure for a diplomatic solution to the Iranian conflict. This interpretation helps reduce the geopolitical risk premium built into the price of oil, even though no new political decisions guarantee, at this stage, an end to hostilities.
Markets are anticipating a possible de-escalation with Iran
The war in the Middle East remains the primary source of uncertainty for energy markets. Clashes involving the United States , Israel, and Iran have caused a sharp rise in oil prices this year, largely due to risks to energy infrastructure and shipping lanes. The Strait of Hormuz, through which a significant portion of global hydrocarbon exports transit, remains under close scrutiny. Any sustained disruption to shipping in this area could lead to further strain on international supplies.
The Democratic victory fuels speculation of increased parliamentary pressure on the US administration. Congress, in particular, possesses budgetary powers that can influence the funding of military operations. Some analysts believe this new political landscape could encourage Washington to prioritize negotiations with Tehran. However, it remains premature to conclude that American foreign policy will change rapidly. Donald Trump retains significant presidential prerogatives, especially in the conduct of diplomatic relations and military operations.
A drop of more than 13% since the beginning of the week
The downward trend didn't begin solely with the announcement of the election results. From the start of the week, oil markets had begun to price in the possibility of diplomatic progress in the Middle East. By Wednesday morning, Brent crude had already fallen by more than 13% compared to the beginning of the week, according to data reported by AFP. Discussions mediated by Qatar had helped to alleviate some concerns about a renewed military escalation. The US results subsequently reinforced this trend.
Investors remain cautious, however. Negotiations between Washington and Tehran have not yet resulted in an agreement that would bring lasting stability to the region. Analysts also point out that the current decline is partly based on political expectations, which could change rapidly. A resumption of airstrikes or a deterioration of the situation in the Strait of Hormuz could trigger a rebound in prices. Conversely, concrete guarantees regarding maritime security could prolong the easing of prices.
What are the consequences for fuel prices in France?
For European consumers, the decline in Brent prices represents a potentially positive development. The price of crude oil directly influences the production cost of gasoline and diesel, although pump prices also depend on refining, transportation, distribution, taxation, and the euro-dollar exchange rate. A sustained drop in international prices can therefore ultimately be passed on to motorists, with the time lag varying depending on the distributor.
In France , this development comes as the government has already announced a reduction in diesel prices at several thousand service stations, following the mobilization of strategic reserves. The combination of increased supply and cheaper oil could help prolong this easing, without guaranteeing a uniform decrease across the country. For transport companies, manufacturers, and households, developments in the coming weeks will be crucial. The fall of Brent crude below $100 is an important signal for the markets, but its economic impact will depend primarily on the duration of this decline and the evolution of the conflict in the Middle East.
