How could US sanctions and Iran's maritime control of Hormuz affect Brent crude oil?
Increased supply risk from Hormuz tensions could drive up Brent crude oil prices The combination of US sanctions targeting Iranian oil revenue and Iran's assertion of control over the Strait of Hormuz increases global supply risk. US efforts have restricted Iranian oil exports, preventing at least $25 billion worth of crude oil in recent months. Simultaneously, the Islamic Revolutionary Guard Corps has warned shipowners that only designated routes are permitted, threatening actions against vessels that ignore its instructions. Because the Strait of Hormuz is a major route for global energy shipments, this heightened uncertainty and potential for disruption could lead to higher volatility and increased costs for Brent crude oil.

How it reaches Brent
-
The U.S. intensified its sanctions campaign targeting the Islamic Revolutionary Guard Corps funding and Iranian oil revenue on October 17, 2026. U.S. forces have prevented Iran from exporting at least $25 billion worth of crude oil in recent months, and the U.S. has frozen nearly $350 million in digital cryptocurrency assets. Meanwhile, Iran plans to announce an exclusion zone outside the Strait of Hormuz for vessels it believes are attempting transit.
The full event17independent outlets -
The Islamic Revolutionary Guard Corps has warned shipowners that any new transit route through the Strait of Hormuz established without coordination with Tehran is 'unacceptable and dangerous'. The IRGC Navy has also claimed an oil supertanker struck a naval mine while attempting to transit the waterway.

The Strait of Hormuz is a key point of contention and a major route for global energy shipments. The IMO monitors the situation, noting that the waterway was effectively closed by Iran, which has been demanding the right to control shipping traffic. Any form of Iranian control could result in appreciably lower flows through the waterway.

Why it matters
Brent crude oil is a global benchmark, and its price is highly sensitive to supply disruptions in major chokepoints like the Strait of Hormuz. The reports indicate that the waterway is crucial for global energy trade, and Iran's assertion of control, coupled with US sanctions on Iranian oil, introduces severe uncertainty into the supply chain.
This situation is part of a broader conflict where the US maintains a naval blockade of Iranian ports, while Iran uses the Strait as a source of leverage. Analysts have warned that if Iran retains strategic control of the waterway, flows through the strait may not fully recover to pre-war levels, suggesting a long-term structural risk to global oil supply.
What we don't know yet
