WTI has broken above its Monday-to-Thursday range of $95.00-$101.00 as Gulf supply faces fresh threats. Two days of Houthi attacks in Saudi Arabia, alongside strikes on vessels departing the Strait of Hormuz, have lifted prices from around $98.50 to just below $103.00. That marks a 22-week high, with WTI trading in the upper fifth of the session’s range.

With attacks affecting supplies still making their way out of the Gulf, WTI’s Thursday advance has extended into Friday. On Thursday, Saudi Aramco (2222.SR) instructed the staff still at its Dhahran headquarters to evacuate after debris from a Houthi drone killed two people at the Shaybah field. UK Maritime Trade Operations reported on Friday that an unidentified projectile had struck a tanker leaving Hormuz near Limah in Oman.
Iran’s barrels remain absent from a market already facing a shortage of Gulf supply, whether the war ends quickly or continues for another year. US Ambassador to the United Nations Waltz told the Financial Times it could last another year, while President Trump said the US could bring it to an end very quickly. According to Ambassador Waltz, the Navy can maintain its blockade of Iran’s ports for the foreseeable future. Kpler expects that blockade to reduce Iran’s Crude Oil revenue to zero by mid-December.
After telling reporters that the US is taking all the Crude Oil it wants out of Hormuz, President Trump is holding a midterm rally in Fort Myers, Florida, on Friday. According to ABC News, The Atlantic and The New York Times, US and Israeli preparations for strikes on Iran following the November 3 midterms are proceeding. No decision has been taken, officials say. Such strikes would target Gulf supply that is already facing attacks.
After exceeding the September 15 peak just above $102.00, the price has returned to trade close to that earlier high. WTI has now gained about $28 from its August 6 low near $74.00, while the 50-day Exponential Moving Average (EMA) has climbed to just over $91.50. For the first time since mid-September, daily momentum has entered overbought territory.

Traded internationally, WTI Oil is a variety of Crude Oil whose initials stand for West Texas Intermediate. Along with Brent and Dubai Crude, it is one of the three main types. Its relatively low gravity earns it the description “light”, while its low sulphur content accounts for the term “sweet”. Regarded as a high-quality oil, WTI is easy to refine. Production takes place in the United States, with distribution through the Cushing hub, known as “The Pipeline Crossroads of the World”. WTI serves as an oil-market benchmark, and its price regularly features in media reports.
Supply and demand underpin WTI Oil prices, just as they do for other assets. Stronger global growth can lift demand, whereas weaker growth can have the reverse effect. Supply disruptions caused by political instability, wars or sanctions can also affect prices. Another important influence is the production policy of OPEC, a group of major oil-producing countries. As oil is traded predominantly in US Dollars, the currency’s value also matters for WTI Crude Oil prices: a weaker US Dollar can make oil more affordable, while a stronger dollar can have the opposite effect.
WTI Oil prices respond to weekly oil inventory figures from the American Petroleum Institute (API) and the Energy Information Agency (EIA), as stock changes reflect shifts in supply and demand. A decline in inventories may point to stronger demand and lift prices. Conversely, a build-up may signal greater supply and weigh on prices. The API releases its report every Tuesday, followed by the EIA the next day. The two reports generally produce similar results, with their figures 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: lower quotas can restrict supply and lift prices, while increased production has the reverse effect. The broader OPEC+ grouping brings in ten additional non-OPEC members, with Russia the most notable among them.
