How could the closure of the Strait of Hormuz affect Brent crude oil prices?
Brent crude prices surge past $107 per barrel due to Hormuz supply disruption The closure of the Strait of Hormuz, a critical maritime chokepoint, has severely restricted the flow of global oil supply. The strait normally handles about one-fifth of global oil consumption, with flow dropping from 20 million barrels per day to 13 million barrels per day. This scarcity forces oil companies to bid prices higher to move remaining oil on the market, directly causing Brent crude futures to surge. On September 14, oil prices rose over 3%, with Brent crude futures reaching $107.82 per barrel.

How it reaches Brent
-
Following Donald Trump's declaration of war against Iran in September 2026, the Strait of Hormuz shipping route closed. In October 2026, nearly a dozen attacks were reported on ships in the Strait of Hormuz or nearby. Despite Donald Trump's claims that Iran's military has been destroyed, Western officials stated that Iran remains well-stocked with ballistic missiles and can quickly rebuild its arsenal.
The full event15independent outlets -
The Strait of Hormuz is a vital passage for global energy, handling about 20% of the world's oil supply. The reduction in flow, from 20 million barrels per day to 13 million barrels per day, creates scarcity. This restriction forces oil companies to bid prices higher to move the remaining product, driving up the benchmark price of Brent crude.

Why it matters
The Strait of Hormuz is one of the world's most critical maritime chokepoints, serving as a vital artery for global energy trade. Because roughly 20% of the world's oil supply passes through this narrow waterway, any disruption immediately translates into global supply concerns and increased risk premiums. This makes the price of Brent crude, a key global benchmark, highly sensitive to the security of the region.
This situation is not isolated; the disruption is compounded by other factors, such as attacks on Saudi Arabia's East-West pipeline, which threatens a volume equivalent to up to 4% of global oil supply. The volatility in the region, driven by the conflict between the United States and Iran, has become a primary factor in global energy market instability.
