Oil prices moved lower on Friday, 16 October 2026, although both major benchmarks remained on course for weekly increases as concerns about Middle Eastern supply disruptions and a substantial decline in US crude inventories continued to support the market.
Brent crude futures fell 47 cents, or 0.44%, to $105.45 a barrel at 07:47 GMT. US West Texas Intermediate (WTI) futures declined by 62 cents, or 0.63%, to $97.35 a barrel.
Despite the daily losses, Brent was heading for a weekly gain of 0.72%, while WTI had risen 5.9%.
The stronger performance of the US benchmark followed a rise of more than 3% on Thursday, when a larger-than-expected reduction in American crude stockpiles highlighted the effects of hurricane-related production interruptions.
European diesel refining margins also weakened after the International Energy Agency (IEA) approved the release of additional fuel supplies.
Middle East Tensions Continue to Influence Crude Prices
Uncertainty surrounding oil shipments through the Strait of Hormuz remained a central factor affecting global crude markets.
Military activity near the waterway has raised concerns about the reliability of supplies moving from the Persian Gulf to international customers.
Analysts at ING said the possibility of continued disruptions was contributing to a substantial geopolitical premium in oil prices.
“Uncertainty in the Middle East and concerns over the sustainability of oil flows through the Strait of Hormuz has the market pricing in a significant risk premium,” ING analysts wrote.
The analysts added that an agreement between the United States and Iran would be needed to strengthen confidence that higher export volumes could be maintained.
Attacks around the Strait of Hormuz have increased over the past ten days, according to the report.
Iran said it was expanding its strikes in response to the US blockade of Iranian ports and stricter sanctions introduced during the previous month.
The escalation has complicated expectations for the recovery of oil shipments through the region.
Kpler Data Shows Hormuz Oil Flows at 68% of Normal Levels
Shipping figures indicated that traffic through the Strait of Hormuz remained substantially below its normal level.
Vessel-tracking company Kpler reported that total clearance through the waterway averaged 11.62 million barrels per day during the seven days ending 13 October.
That compared with a baseline of 17.15 million barrels per day, meaning reported volumes were approximately 68% of the reference level.
The difference represents a reduction of around 5.53 million barrels per day.
Kpler analysts linked the decline to increased Iranian military activity.
“Intensified Iranian attacks drove Gulf crude flows sharply lower,” the analysts said in a report published Thursday.
They also indicated that the recovery in shipping activity was likely to be slower and less consistent without a comprehensive political settlement.
The reduced flow of crude through Hormuz remains a significant source of uncertainty for energy markets, particularly while military activity continues.
US Crude Stockpile Decline Strengthens WTI Performance
A larger-than-expected reduction in US crude inventories provided additional support for American oil prices during the week.
WTI futures gained more than 3% on Thursday following the inventory figures.
The decline in stockpiles was partly associated with hurricane-related shutdowns that interrupted domestic oil production.
Such disruptions can temporarily reduce the amount of crude available to the market, affecting both inventories and price expectations.
The development contributed to WTI’s 5.9% weekly advance, considerably exceeding Brent’s 0.72% increase.
However, the US benchmark gave back some of those gains on Friday, declining 0.63% to $97.35 a barrel.
Brent also weakened, falling 0.44% to $105.45.
The contrasting daily and weekly movements reflected continued uncertainty about both regional supply interruptions and global market conditions.
IEA Diesel Release Reduces European Refining Margins
European diesel refining margins declined after the International Energy Agency agreed on Thursday to release more than 20 million barrels of diesel.
Margins fell by nearly 2% on Friday to $78.67 a barrel.
The additional supplies are intended to provide relief to a market affected by disruptions associated with the conflicts in Ukraine and Iran.
European diesel refining margins had climbed to approximately $95 a barrel during September as supply availability tightened.
The planned release could help ease some of those pressures by increasing the amount of fuel available to buyers.
However, the effect on prices and refining margins will depend on the timing and distribution of the additional diesel.
The decline in margins occurred alongside continued concerns about crude oil supplies, illustrating the different factors affecting refined products and unprocessed petroleum.
Yemen Attacks Add to Regional Security Concerns
Additional military developments in Yemen contributed to uncertainty across the Middle East.
According to the report, Houthi forces launched missiles towards the presidential palace complex in Aden on Thursday, killing two guards.
The Saudi-led coalition involved in Yemen also reported dozens of attacks targeting infrastructure in Saudi Arabia.
The incidents occurred against a backdrop of escalating regional tensions.
Security concerns affecting energy facilities and maritime routes can influence the cost and availability of oil transportation.
The latest developments therefore added to the broader supply risks being assessed by traders.
Washington Considers Changes to Shadow Fleet Sanctions
The US administration is reportedly examining whether to lift sanctions on certain oil tankers associated with the so-called shadow fleet.
A US official said on Wednesday that the discussions were intended to help reduce record global shipping costs.
The vessels under consideration have transported oil and petroleum products from countries including Russia, Iran and Venezuela.
The potential changes follow President Donald Trump’s temporary suspension of sanctions on Russian diesel fuel.
That decision attracted criticism from Ukrainian President Volodymyr Zelenskiy, European governments and some members of Trump’s Republican Party.
The wider proposal concerning shadow fleet vessels remains under consideration, with no final decision confirmed in the report.
If implemented, changes to sanctions could affect tanker availability and international freight rates, although the scale of any impact remains uncertain.
Oil Markets Continue to Assess Supply and Geopolitical Risks
Oil prices remained on track for weekly gains despite Friday’s decline, supported by reduced US inventories and concerns about Middle Eastern export flows.
WTI outperformed Brent during the week, reflecting the influence of domestic stockpile data and hurricane-related production disruptions.
Meanwhile, Kpler’s shipping figures indicated that oil movements through the Strait of Hormuz remained well below their normal level.
The IEA’s decision to release additional diesel provided a separate source of supply relief for European fuel markets.
Further developments involving the United States, Iran, regional shipping security and energy sanctions are likely to remain important considerations for crude oil prices.
