Brent touches US$110 for the first time since May on Middle East tensions

Brent crude and West Texas Intermediate, or WTI, are two important types of crude oil. Their quoted prices are used as benchmarks, meaning other oil prices are compared with them. This gives buyers, sellers, producers, and investors a common reference for valuing oil.

They are useful because they are actively traded and have recognized quality and delivery markets. Brent mainly reflects oil traded around the North Sea and is widely used internationally. WTI reflects a major US market. Changes in either price can signal changing expectations about supply, demand, transport, or risk.

The article shows how benchmarks communicate market stress. Brent settled at US$109.86, while WTI reached US$101.41. Brent rose 3.7% on Friday, and WTI rose 3.5%. These prices let readers quickly compare the effect of Middle East tensions and uncertainty about Russian diesel supplies.

The immediate price increase was substantial. Brent crude gained 3.7% in one trading day and settled at US$109.86. WTI rose 3.5% to US$101.41. Brent reached its highest level since May 19, showing that the move lifted prices to a multi-month peak.

The weekly comparison reveals a stronger buildup, particularly for WTI. Over the full week, Brent gained 4.9%, while WTI gained 10.4%. WTI’s weekly increase was more than twice Brent’s, even though their single-day rises were similar. This indicates that the market had already been under pressure before Friday.

The gains reflect several overlapping concerns. Attacks around the Strait of Hormuz threatened Gulf crude flows, while uncertainty grew over Russia’s ability to supply diesel. The article also links price movement to the Ukraine war. Together, these risks made traders expect tighter supplies and pushed benchmark prices higher.

Oil prices respond not only to actual losses but also to the risk of future supply disruption. A missile attack near an important export route can make traders worry that ports, ships, pipelines, or loading facilities may be targeted next. That risk raises the expected value of oil available elsewhere.

The article gives a clear example. A Saudi-led coalition intercepted and destroyed a ballistic missile launched toward Yanbu, a Red Sea port used to bypass the Strait of Hormuz. Initial reports found no damage to its facilities, yet prices rebounded. The threat still suggested that alternative routes and regional exports could become less secure.

Attacks around Hormuz had intensified over ten days, and Kpler said Gulf crude flows had fallen sharply. Even without confirmed physical damage, reduced movement and fear of more attacks can tighten the market. Kpler forecast a slow, uneven recovery unless a political deal is reached, keeping upward pressure on prices.

The Strait of Hormuz is a narrow waterway linking the Persian Gulf with the Gulf of Oman and the wider ocean. It is important because large volumes of oil and fuel move through or near this route. The article specifically connects attacks around Hormuz with sharply lower Gulf crude flows.

Its strategic importance is illustrated by Saudi Arabia’s use of Yanbu, a Red Sea port, to bypass the strait. When the Saudi-led coalition reported that it had destroyed a ballistic missile aimed at Yanbu, markets reacted. The missile threatened a route designed to reduce dependence on Hormuz, showing how security concerns can spread beyond the waterway itself.

The article says attacks intensified over ten days as Iran responded to a US blockade of its ports and tougher sanctions. Kpler forecast a slow and uneven recovery in Gulf crude flows without a political deal. That uncertainty helped push Brent above US$110 a barrel.

Refineries turn crude oil into usable fuels, including diesel. If an attack damages or shuts part of a refinery, the facility may process less crude or produce less diesel. Even a temporary suspension can therefore reduce expected fuel supplies and make buyers compete more strongly for available cargoes.

The article reports that a drone attack forced the suspension of a distillation unit at Russia’s Ryazan refinery. Dennis Kissler of BOK Financial said it was questionable how much diesel Russia could actually deliver to markets. The concern was not only physical damage, but also the refinery’s reduced ability to keep producing and exporting fuel.

This matters because diesel is a widely needed transport and industrial fuel. The article also says Donald Trump announced a deal with Vladimir Putin for Russia to supply about 4.8 million tonnes of diesel. If attacks interrupt that supply, the expected volume may not arrive, adding pressure to energy markets already affected by Middle East tensions.

Emergency stock releases can reduce market pressure by adding fuel when traders fear supplies may fall. More barrels give buyers another source and can narrow the gap between expected demand and available supply. The announcement itself may also calm markets by showing that governments and agencies can respond to disruption.

The article says the International Energy Agency agreed to release more than 20 million barrels of fuel. The US Department of Energy offered an exchange of up to 17 million barrels from its strategic reserve. These supplies could partly replace barrels threatened by attacks near Hormuz or uncertainty over Russian deliveries.

The releases cannot automatically solve every problem. They may be temporary, and the article does not state when all barrels will reach buyers. Still, they can slow price increases by improving confidence and physical availability. Their effect depends on the size and duration of the disruptions affecting crude and diesel markets.

Crude oil is a raw mixture of hydrocarbons produced from underground reservoirs. Diesel is a finished fuel used in engines and other equipment. They are not interchangeable products. Crude must first be processed so its different components can be separated and converted into fuels with suitable properties.

A refinery uses units such as distillation equipment to heat crude and separate it into fractions. Further processing can improve those fractions and help produce diesel. This is why the article’s report about a suspended distillation unit at Russia’s Ryazan refinery matters: a disruption to processing can reduce the amount of diesel available, even if crude remains in the country.

The article links this risk to uncertainty over Russian deliveries. Dennis Kissler questioned how much diesel Russia could send to markets after the drone attack. The issue is therefore not simply how much crude exists, but whether refineries can keep turning crude into usable fuel for international buyers.
