US-Iran diplomatic efforts buoy trader sentiment, sending WTI down over 5%

WTI Oil slides more than 5% under pressure from US-Iran diplomatic developments.
The Strait of Hormuz will reopen only if the US meets Iran’s demands, Tehran says.
Markets remain focused on Strait of Hormuz shipping risks and the uncertain prospect of US military action.

Easing fears of further supply disruptions are weighing heavily on West Texas Intermediate (WTI) on Monday, with prices down more than 5% following encouraging US-Iran diplomatic headlines. The US crude benchmark is trading near $96.65 a barrel at the time of writing, compared with Friday’s high of $104.03, its strongest level since May.

Selling intensifies following comments from Iranian President Masoud Pezeshkian that the Supreme Leader had given the government certain negotiating powers, according to ISNA. Earlier, an Axios report that US President Donald Trump favours allowing more time for diplomacy with Iran had already sent oil prices lower at the start of the week.

Describing consultations via Qatari and Pakistani mediators as “very intensive,” Iranian Foreign Minister Abbas Araghchi said Tehran had put forward its terms and plan. Progress, he added, rested on Washington’s “political rationality.” Araghchi reiterated that the Strait of Hormuz would reopen only if the US accepted Iran’s demands, which include an end to its naval blockade and the lifting of sanctions.

With no final agreement announced, renewed US military action after Tuesday’s midterm elections remains a risk. Washington had cautioned Gulf states last week to prepare for potential strikes against Iran, the Wall Street Journal reported. At a campaign rally in Iowa on Sunday, Trump also warned that “at some point we’re going to have to give them the hammer.”

Diplomatic efforts have not removed the risks facing shipping. According to Iranian state media, Iran’s Islamic Revolutionary Guard Corps said two crude oil tankers had struck sea mines in the Strait of Hormuz and caught fire. There has been no independent verification of the claim.

Continued disruption to Gulf exports is also keeping the supply outlook uncertain. Against this backdrop, seven OPEC+ producers agreed on Sunday to leave December production targets unchanged. A further meeting is scheduled for November 29, when the group will review its January production plans.

WTI Oil: key questions answered

What defines WTI Oil?

Traded in international markets, WTI Oil is a variety of crude oil whose initials stand for West Texas Intermediate. Alongside Brent and Dubai Crude, it is one of the three major types. Its relatively low gravity and sulphur content earn it the descriptions “light” and “sweet”, respectively, and it is regarded as a high-quality oil that can be refined easily. Produced in the United States, WTI is distributed through the Cushing hub, known as “The Pipeline Crossroads of the World”. WTI serves as an oil market benchmark, with its price regularly cited in media coverage.

What determines movements in WTI Oil prices?

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 arising from political instability, wars or sanctions can also affect prices. Another important influence is OPEC, a group of major oil-producing countries whose decisions help shape prices. Since oil is traded predominantly in US Dollars, the value of the US Dollar also matters for WTI Crude Oil: a weaker dollar can make oil more affordable, while a stronger dollar can make it less affordable.

Why do inventory reports affect WTI Oil prices?

WTI Oil prices respond to weekly oil inventory reports from the American Petroleum Institute (API) and the Energy Information Agency (EIA), as changes in stockpiles reflect shifts in supply and demand. A fall in inventories can signal stronger demand and push prices higher. Conversely, rising inventories can 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 findings tend to be close, coming within 1% of one another 75% of the time. As the EIA is a government agency, its figures are regarded as more reliable.

Why do OPEC decisions matter for WTI Oil prices?

Decisions by OPEC (Organization of the Petroleum Exporting Countries) frequently affect WTI Oil prices. The group comprises 12 oil-producing nations that jointly set members’ production quotas at meetings held twice a year. A reduction in quotas can constrain supply and lift oil prices, whereas an increase in production has the reverse effect. The broader OPEC+ group includes ten additional non-OPEC members, with Russia the most notable among them.
