WTI falls 9% as hopes of an end to Iran war grow after US election results

  • WTI drops below $90 as markets assess how the US midterm elections could affect the Iran war.
  • A Democratic win in the US midterm elections increases the likelihood of political pressure to bring the war with Iran to an end.
  • An unexpected draw in US crude inventories fails to stem the steep fall in oil prices.

A 9% fall in West Texas Intermediate (WTI) on Wednesday leaves the US crude benchmark trading at around $87 a barrel at the time of writing, a four-week low. Although the immediate catalyst for the sell-off is unclear, it could reflect the Democrats’ victory in the US midterm elections and the resulting potential for pressure on President Donald Trump to end the war with Iran.

With Democratic majorities in both the House and Senate, lawmakers could have greater room to curb funding for the war with Iran. “We will end the war,” said Senate Democratic Leader Chuck Schumer, who added that some Republicans had joined the initiative.

Having previously suggested that attacks could restart after the elections, Trump has since downplayed the likelihood of imminent military action. He said the US had no immediate plans to strike Iran.

According to CBS News, Trump is also discussing the possible replacement of Defense Secretary Pete Hegseth with advisers, although a decision has yet to be reached. Trump “has full confidence in Secretary Hegseth.” That was the response from White House spokeswoman Anna Kelly.

Diplomatic efforts continue, but the outlook for negotiations remains uncertain. Qatari mediators travelled to Tehran on Monday evening to discuss a potential US-Iran agreement with Iranian Foreign Minister Abbas Araghchi, Reuters reported.

US crude oil stocks declined by 865K barrels last week, rather than rising by the 900K barrels expected, figures from the Energy Information Administration (EIA) showed. The preceding week had recorded a draw of 1.462 million barrels.

WTI Oil Explained

Traded internationally, WTI oil takes its name from West Texas Intermediate and ranks alongside Brent and Dubai Crude as one of three major crude oil types. Its relatively low gravity and sulphur content earn it the descriptions “light” and “sweet”, respectively. Regarded as a high-quality oil, it is straightforward to refine. WTI originates in the United States and reaches the market through the Cushing hub, known as “The Pipeline Crossroads of the World”. As a benchmark for the oil market, its price regularly features in media coverage.

Supply and demand underpin WTI oil prices, as they do those of other assets. Stronger global growth can therefore lift demand, while weaker growth can have the reverse effect. Supply disruptions caused by political instability, wars or sanctions can also affect prices. Another important influence is policy set by OPEC, the group of major oil-producing countries. Since oil is traded predominantly in US dollars, movements in the currency also shape WTI crude oil prices: a weaker US dollar can make oil more affordable, while a stronger dollar can do the opposite.

WTI oil prices respond to the weekly inventory figures released by the American Petroleum Institute (API) and the Energy Information Agency (EIA), as stock movements reflect shifts in supply and demand. A draw in inventories may signal stronger demand and lift oil prices; a build may point to greater supply and weigh on prices. The API publishes its figures each Tuesday, followed by the EIA the next day. The two sets of results tend to be similar, coming within 1% of one another 75% of the time. 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 that make up OPEC (Organization of the Petroleum Exporting Countries) jointly agree production quotas for member countries. These decisions frequently influence WTI oil prices. Lower quotas can restrict supply and push prices higher, whereas an increase in OPEC output has the reverse effect. The broader OPEC+ group brings in ten additional countries outside OPEC, with Russia the most notable among them.
