At around $85.00 per barrel in Thursday’s Asian trading, West Texas Intermediate (WTI) oil is extending its decline for a fifth consecutive day. The retreat in crude prices comes as negotiations between the United States (US) and Iran remain at an impasse, although neither side is currently pursuing further escalation.

Nuclear issues must feature in any preliminary negotiations to end the war, Washington maintains. A senior Iranian security official, however, dismissed that central condition, saying Tehran would not permit a single atom of its enriched nuclear material to leave the country. Iran has also restated its demand that the US remove sanctions and bring the naval blockade to an end before the Strait of Hormuz reopens.
October crude production by OPEC+, the alliance comprising the Organization of the Petroleum Exporting Countries and partners including Russia, rose sharply. The group produced 41.23 million barrels per day that month, according to OPEC’s monthly report published on Wednesday. Output was about 2.04 million barrels per day higher than in September, with a substantial increase from Saudi Arabia accounting for most of the rise.
With the geopolitical outlook for oil still highly uncertain, Rabobank analysts warn that markets cannot yet rule out a renewed escalation in US–Iran tensions. They note that “presuming this was achieved last weekend, where other reports suggest the US was moments away from striking, that means we could still be looking at more fighting by mid- to end-November, at which time a third US aircraft carrier will be in the region.” Describing the possible timetable and accumulation of US military assets as “a distressing report,” they highlight the continuing risk of further conflict.
Traded internationally, WTI is a grade of crude oil whose initials stand for West Texas Intermediate. Alongside Brent and Dubai Crude, it is one of three major grades. Its relatively low gravity and sulphur content earn it the descriptions “light” and “sweet”, respectively. Regarded as a high-quality oil, WTI is straightforward to refine. It originates in the United States and is distributed through the Cushing hub, known as “The Pipeline Crossroads of the World”. WTI serves as an oil market benchmark, and its price is regularly cited in the media.
Supply and demand underpin WTI oil prices, as they do those of other assets. Stronger global growth can lift demand, while weaker growth can have the reverse effect. On the supply side, political instability, wars and sanctions can cause disruption and affect prices. Decisions taken by OPEC, a grouping of major oil-producing countries, are another important influence. Because oil is traded predominantly in US Dollars, WTI crude prices are also affected by the currency’s value: a weaker US Dollar can make oil more affordable, whereas a stronger dollar can do the opposite.
WTI prices respond to the weekly oil stock reports issued by the American Petroleum Institute (API) and the Energy Information Agency (EIA), as inventory movements reflect shifts in supply and demand. A decline in stocks can signal stronger demand and push oil prices higher. Conversely, rising inventories can indicate 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 are generally 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 set production quotas for their members. These decisions frequently influence WTI oil prices. Reducing quotas can constrain supply and lift prices, while increasing production has the reverse effect. The broader OPEC+ alliance brings in ten additional non-OPEC members, of which Russia is the most notable.
