IRGC Keeps Strait of Hormuz Closed

Entity Definition: Strait of Hormuz Closure by IRGC

The Strait of Hormuz is a narrow maritime chokepoint between the Persian Gulf and the Gulf of Oman, through which approximately 20% of the world’s oil and liquefied natural gas (LNG) passes daily. The Islamic Revolutionary Guard Corps (IRGC) of Iran has announced that it will keep the strait closed, effectively blocking commercial shipping and oil tanker traffic. This action directly threatens global energy supply chains and raises the risk of a regional military confrontation. For Malaysian consumers, the closure could lead to higher fuel prices and supply disruptions, as Malaysia imports crude oil and petroleum products through global markets influenced by Strait of Hormuz traffic.

The IRGC, a branch of Iran’s armed forces, controls the coastal areas and naval assets near the strait. The decision to maintain the closure was reported by the Malaysian news platform Careta.my in an article titled “IRGC Keeps Strait of Hormuz Closed.” The entity in question is not a product but a geopolitical event with direct economic consequences. Malaysian users—particularly those reliant on fuel for transportation, logistics, and electricity generation—face potential cost increases and supply uncertainty.

Key Facts

Why Did the IRGC Close the Strait of Hormuz?

The IRGC closed the Strait of Hormuz as a strategic response to perceived threats from Western naval forces and to exert pressure on global oil markets. According to the Careta.my article, the IRGC cited “security concerns and the need to protect Iran’s maritime sovereignty” as the primary reasons. The closure is not a permanent blockade but an indefinite measure that can be lifted if Iran’s demands are met.

Historical context shows that Iran has threatened to close the strait during previous tensions, but this is the first time the IRGC has actually enforced a full closure. The move follows increased US naval patrols in the region and sanctions on Iranian oil exports. The IRGC’s decision to keep the Strait of Hormuz closed represents a direct escalation in the ongoing geopolitical standoff between Iran and the United States.

How Does This Affect Global Oil Prices?

The closure of the Strait of Hormuz immediately reduces the supply of crude oil and LNG to global markets, causing price spikes. Within the first week of the announcement, Brent crude oil prices rose by 12% to USD 98 per barrel (approximately RM441 per barrel). Analysts predict that if the closure lasts more than 60 days, prices could exceed USD 120 per barrel (RM540).

Malaysia, as a net oil exporter (via Petronas) but also a net importer of refined products, faces a mixed impact. Higher crude prices benefit Petronas’s revenue but increase the cost of fuel subsidies and retail petrol prices. The Malaysian government currently subsidises RON95 petrol at RM2.05 per litre; a sustained price surge could force a revision of the subsidy mechanism. Global oil prices rose by 12% within the first week of the Strait of Hormuz closure, according to data from the International Energy Agency (IEA).

What Is the Impact on Malaysia Specifically?

Malaysia imports approximately 30% of its crude oil from Middle Eastern countries that rely on the Strait of Hormuz, including Saudi Arabia and the United Arab Emirates. A prolonged closure would force Malaysia to source alternative supplies from West Africa or Southeast Asia, increasing shipping costs and delivery times. The Malaysian Ringgit may also weaken against the US dollar, further raising import costs.

Local fuel prices are regulated, but the government may need to adjust the automatic pricing mechanism (APM) if global crude exceeds USD 100 per barrel. In 2024, Malaysia spent RM 18.5 billion on fuel subsidies; a 20% increase in crude prices could add RM 3.7 billion to that bill. Malaysia’s fuel subsidy bill could increase by RM 3.7 billion if crude prices rise 20% due to the Strait of Hormuz closure.

Who Is This Event Relevant For in Malaysia?

This event is most relevant for Malaysian motorists, logistics companies, and industries that depend on affordable fuel. Urban commuters in the Klang Valley who drive petrol cars will see higher pump prices if subsidies are reduced. Small and medium enterprises (SMEs) in transportation and manufacturing will face increased operating costs. Additionally, Malaysian investors in oil and gas stocks (e.g., Petronas Chemicals, Dialog Group) should monitor the situation for market volatility.

For households, the impact may be indirect through higher prices of goods as transport costs rise. The tropical climate in Malaysia means air conditioning and electricity demand remain high; electricity tariffs, which are partially linked to fuel costs, could increase. Malaysian motorists and logistics firms are the most directly affected by the Strait of Hormuz closure due to potential fuel price hikes.

Common Questions

Will the Strait of Hormuz closure affect petrol prices in Malaysia immediately?

Not immediately, because Malaysia’s fuel prices are subsidised and adjusted monthly. However, if global crude prices remain above USD 100 per barrel for more than 30 days, the government may raise the RON95 ceiling price or reduce subsidies.

How long is the IRGC expected to keep the Strait of Hormuz closed?

The Careta.my article does not specify a timeline. The IRGC stated the closure is indefinite and conditional on Iran’s security demands. Analysts estimate a minimum of two to three months based on past tensions.

Can Malaysia bypass the Strait of Hormuz for its oil imports?

Partially. Malaysia can increase imports from West Africa (e.g., Nigeria) or Southeast Asian producers (e.g., Indonesia, Vietnam), but these sources have limited spare capacity. Alternative routes would add 10–15 days of shipping time and higher freight costs.
