Oil prices moved higher on Wednesday, November 4, 2026, as investors evaluated the impact of the US midterm election results and growing uncertainty surrounding the ongoing conflict with Iran.
Brent crude oil futures rose 0.6% to $104.20 per barrel, while US West Texas Intermediate (WTI) futures gained 0.5% to $96.59, according to early trading figures recorded at 06:57 GMT.
The gains followed a volatile period for energy markets, with traders weighing the possibility of further US military action against Iran against renewed diplomatic efforts to prevent an escalation.
Meanwhile, an unexpected decline in US crude oil inventories provided additional support for prices.
Oil Prices Rise Following US Midterm Election Results
The US midterm elections delivered significant political changes, with Democrats securing majorities in both the House of Representatives and Senate.
The outcome represents a major setback for President Donald Trump’s Republican Party and could complicate the administration’s legislative agenda during the remainder of his second term.
However, energy traders remain particularly focused on how the election results could influence Washington’s approach to the Middle East conflict.
Investors are assessing whether the administration will pursue additional military operations against Iran or prioritize diplomatic negotiations.
Although Congress can influence foreign policy through legislation and oversight, the president retains substantial authority over military and diplomatic decisions.
Consequently, uncertainty surrounding Washington’s next steps continues to affect oil market sentiment.
US-Iran Conflict Keeps Energy Markets on Edge
Geopolitical developments remain a major source of volatility in global oil markets.
Earlier this week, the United States conducted limited military strikes against Iranian air defense installations on Qeshm Island, near the strategically important Strait of Hormuz.
US officials described the operations as defensive measures, indicating that they were not intended to signal an immediate return to large-scale military action.
President Trump subsequently stated that Washington had no immediate plans to launch additional strikes.
Nevertheless, the combination of military activity and diplomatic uncertainty has made it difficult for investors to determine the near-term direction of crude prices.
Before the midterm elections, expectations of renewed military operations had contributed to a sharp rally in oil.
Prices reached their highest levels in approximately six months as traders incorporated additional geopolitical risk into crude valuations.
However, indications that negotiations could continue triggered a subsequent reversal.
Iran Peace Negotiations Remain Far From Agreement
Diplomatic efforts between Washington and Tehran have intensified as international mediators seek to prevent further escalation.
According to reports, both countries are reviewing new proposals intended to address outstanding disagreements and establish conditions for a broader settlement.
Qatar has increased its mediation efforts, helping facilitate exchanges between American and Iranian officials.
However, significant differences remain between the two sides.
Iranian officials have expressed dissatisfaction with Washington’s response to their conditions for reopening the Strait of Hormuz.
A senior Iranian official also indicated that the countries remain far from reaching a comprehensive agreement.
The lack of a clear diplomatic breakthrough continues to create uncertainty for energy traders.
Although successful negotiations could reduce geopolitical risk premiums, renewed military escalation could push crude prices higher.
Strait of Hormuz Supply Risks Support Crude Oil
The Strait of Hormuz remains one of the most important factors influencing global energy markets.
The narrow waterway connects the Persian Gulf with international shipping routes and is a critical passage for oil exports from major Middle Eastern producers.
Any prolonged disruption to tanker traffic could restrict crude supplies and increase transportation costs.
Reports of another attack on an oil tanker in the region have added to concerns surrounding maritime security.
Even when physical oil production remains relatively stable, threats to shipping can influence prices by increasing insurance costs, delivery delays and uncertainty over future supply.
As a result, traders continue monitoring developments involving Iranian military activity and the security of commercial vessels.
The risk of disruption to energy shipments remains an important source of support for oil prices, despite ongoing diplomatic efforts.
US Crude Oil Inventories Fall by 5.27 Million Barrels
Alongside geopolitical developments, fresh US inventory data provided another supportive signal for crude markets.
The American Petroleum Institute (API) reported that domestic crude oil inventories declined by approximately 5.267 million barrels during the week ending October 30.
The decrease contrasted sharply with market expectations for an increase in crude stockpiles.
A larger-than-anticipated inventory draw can indicate tighter supply conditions, stronger refinery demand or changes in crude imports and exports.
Consequently, the figures helped offset some of the downward pressure associated with expectations of diplomatic progress.
Gasoline inventories increased by approximately 1.427 million barrels, while distillate inventories also declined.
The mixed petroleum product data suggest that supply and demand conditions continue to vary across different parts of the energy market.
Investors will also monitor official inventory figures from the US Energy Information Administration to assess whether they confirm the industry’s preliminary estimates.
Brent and WTI Outlook Depends on Iran Diplomacy
Oil markets remain caught between two competing influences.
On one hand, the possibility of further military escalation in the Middle East creates significant supply risks.
On the other, continued negotiations between Washington and Tehran could reduce concerns about a prolonged regional conflict.
The latest inventory figures provide some underlying support for crude prices, particularly if additional data confirm tightening US supplies.
However, uncertainty surrounding the political and military situation could continue producing sharp price fluctuations.
Investors will closely monitor statements from the Trump administration, developments in diplomatic negotiations and any additional incidents affecting shipping through the Strait of Hormuz.
For now, Brent crude remains above $104 per barrel as geopolitical uncertainty and declining US inventories support energy markets.
The next significant movement in oil prices may depend on whether diplomatic progress reduces supply concerns or renewed military tensions increase the risk of disruption to Middle Eastern crude exports.
