Iran Threatens Strait of Hormuz Closure Amidst Escalating Tensions

Jakarta, Indonesia – Iran’s parliament is urging the government to close the Strait of Hormuz in response to the recent death of Iran’s Supreme Leader, Ayatollah Ali Khamenei, and over 40 high-ranking Iranian officials, significantly escalating regional conflict. The potential closure of this vital waterway is now under close global scrutiny.

Parliamentary Support and National Security Council Review

Iran’s parliament has voiced support for closing the Strait of Hormuz, however, the final decision rests with Iran’s national security council. If enacted, this would mark a significant escalation, representing the first such action by Iran since the start of the conflict with Israel in 1979.

Strategic Importance of the Strait of Hormuz

The Strait of Hormuz, a narrow waterway only about 33 kilometers wide, is a critical chokepoint for global energy supplies. Approximately 20% of the world’s oil passes through the strait, making it one of the busiest and most strategically important sea lanes globally. Around 22% of global oil supply, equivalent to roughly 21 million barrels per day in 2022, transits the Strait. Approximately 20% of global liquefied natural gas (LNG) trade passed through the Strait in 2022.

Beyond oil, the Strait is likewise crucial for transporting petrochemicals and other essential goods. Disruption to this route could have severe consequences for global energy prices, supply chains, and economies worldwide.

Geopolitical Landscape and Regional Tensions

The Strait of Hormuz is bordered by the United Arab Emirates (UAE) and Oman to the west, Iran to the north, and Saudi Arabia and Bahrain to the south. This proximity to powerful nations and vital resources makes the Strait a focal point for geopolitical tension.

Iran, controlling much of the northern coastline, has frequently threatened to block the Strait during periods of conflict. In 2019, during heightened tensions with the United States, Iran seized a tanker passing through the Strait, raising global concerns about maritime security and oil market stability.

Military Presence and Security Challenges

The Strait of Hormuz is a region of heightened military presence. The United States, along with NATO allies, regularly patrols the Strait to ensure freedom of navigation. The UAE and Saudi Arabia also maintain a military presence to protect their oil facilities and infrastructure. This concentration of military forces increases the risk of conflict, with Iran repeatedly threatening to close the Strait in response to military action against it.

Historical Precedents and Iran’s Approach

During the Iran-Iraq War (1980-1988), both countries routinely threatened oil shipments, attacking tankers in the Gulf. In 1988, the USS Vincennes shot down an Iranian passenger plane, killing 290 people in an incident the U.S. Deemed accidental. More recently, in 2010, a Japanese oil tanker was attacked by a group linked to al-Qaeda.

Despite repeated threats, Iran has never fully closed the Strait of Hormuz. The Strait is also a vital route for Iran’s own oil exports. Historically, Iran has favored limited actions, such as targeted attacks or sabotage, over a complete closure that could trigger a wider conflict with the U.S. And its allies.

Pertamina’s Preparations

In response to the escalating situation, PT Pertamina (Persero) is preparing alternative operational routes for oil carriers to ensure continued supplies to Indonesia. Pertamina’s Vice President for Corporate Communication, Fadjar Djoko Santoso, stated the company has prepared alternative routes through various points to avoid disruptions to oil supplies from the Middle East. Pertamina also maintains diversified crude oil sources to ensure national energy security.
