At around $102.25 a barrel at the time of writing, West Texas Intermediate (WTI) is more than 2.50% higher on Wednesday. The US crude benchmark is recovering from the previous two days’ losses, with continuing tensions in the Middle East sustaining a geopolitical risk premium in oil prices.

Behind the rise was a claim by Yemen’s Iran-aligned Houthis that they had launched a missile strike on Saudi Arabia’s largest oil refinery on Tuesday. There was no immediate confirmation from Saudi authorities of the reported attack on the facility, which has a capacity of 550,000 barrels per day.
Supply concerns were compounded by a Wall Street Journal report that Washington had told Gulf states to prepare for a potential brief but intense military campaign against Iran following the US midterm elections on November 3. Asked by reporters on Wednesday about a possible post-election attack on Iran, US President Donald Trump said “anything is possible”.
Despite these developments, diplomatic efforts remain under way. Posting on X, Iranian Foreign Minister Abbas Araghchi said Iran “continues to give diplomacy a chance to succeed”. He added that it remains in close contact with intermediaries about ideas for putting its seven-day plan into effect in less than a week. Under the proposal, the Strait of Hormuz would reopen and talks would resume if the US accepted Iran’s demands.
A new draft agreement had been delivered to Iran by Qatari mediators in Tehran on Sunday, Reuters reported earlier on Wednesday. Iran was considering the proposal, with a response expected by the end of the week. An Iranian official, however, rejected it as unacceptable.
Pressure on global supplies was also evident in the World Bank’s latest outlook. The bank projects that oil supply will contract by 5.2% in 2026, the sharpest fall in more than four decades apart from the 2020 recession, while energy prices will climb 32% to a four-year high. It cautioned that a fresh escalation in the Middle East or further damage to Russian oil infrastructure could lift energy prices further.
Meanwhile, figures from the Energy Information Administration (EIA) showed a 1.462 million-barrel fall in US crude oil inventories, larger than the expected 300,000-barrel draw. Stocks had declined by 3.061 million barrels in the preceding week.
Sunday’s OPEC+ meeting is the next focus for traders. Sources quoted by Reuters expect producers to leave December output targets unchanged.
Traded on international markets, WTI is a grade of crude oil whose name stands for West Texas Intermediate. Alongside Brent and Dubai Crude, it is one of the three major grades. Its relatively low gravity and sulphur content earn it the descriptions “light” and “sweet”, respectively. These characteristics make it a high-quality oil that is straightforward to refine. Produced in the United States, WTI is distributed through the Cushing hub, known as “The Pipeline Crossroads of the World”. Its role as an oil market benchmark means that WTI prices are regularly cited in the media.
Supply and demand underpin WTI oil prices, as they do those of all assets. Stronger global growth can therefore increase demand, while weaker growth can have the reverse effect. On the supply side, political instability, conflict and sanctions can cause disruptions that affect prices. Decisions taken by OPEC, a group of major oil-producing countries, are another important influence. WTI crude prices also respond to the value of the US dollar: because oil is traded mainly in US dollars, a weaker dollar can make it more affordable, with a stronger dollar having the opposite effect.
WTI oil prices respond to the weekly inventory reports issued by the American Petroleum Institute (API) and the Energy Information Agency (EIA), as movements in stocks reflect shifts in supply and demand. Falling inventories may signal stronger demand and lift oil prices; rising stocks may point to greater supply and weigh on prices. The API releases its report each Tuesday, followed by the EIA the next day. The two sets of figures generally show similar results, differing by no more than 1% on 75% of occasions. As the EIA is a government agency, its data is regarded as more reliable.
At meetings held twice a year, the 12 oil-producing nations in OPEC (Organization of the Petroleum Exporting Countries) jointly set production quotas for member countries. These decisions frequently influence WTI oil prices. A reduction in quotas can restrict supply and lift prices, whereas an increase in production has the reverse effect. The wider OPEC+ group brings in ten additional countries outside OPEC, of which Russia is the most notable.
