Iran's Revolutionary Guards Threaten to Close Strait of Hormuz, Warn of Attacks on Ships

In a dramatic escalation of regional tensions, Iran's Revolutionary Guards have declared the strategic Strait of Hormuz closed, issuing a stark warning that any vessel attempting to pass through this vital waterway will face immediate attack. Ebrahim Jabari, a senior adviser to the commander-in-chief of the Islamic Revolutionary Guard Corps (IRGC), stated unequivocally that ships trying to transit the narrow passage would be "set ablaze." This aggressive posture comes amid a backdrop of heightened military activity across the Middle East, including unconfirmed reports of a US F-15 fighter jet downed in Kuwait and Israeli strikes on Hezbollah targets in Beirut.

The Strait of Hormuz: A Critical Global Chokepoint

The Strait of Hormuz, situated between Iran and Oman, represents one of the most crucial maritime chokepoints in global trade. It serves as the primary conduit connecting the Persian Gulf to the Gulf of Oman and, ultimately, the Arabian Sea. Although bordered by Iran and Oman, the strait is internationally recognized as a key shipping lane essential for the flow of energy resources worldwide.

The threat of closure has already sent shockwaves through global energy markets, with oil prices experiencing a sharp upward spike due to fears of prolonged disruption. While there has been no formal international confirmation that the strait is completely sealed, tanker traffic has noticeably declined, and reports of electronic interference and attacks near the waterway have significantly heightened alarm among shipping companies and governments.

A Vital Artery for Global Oil and Gas Supplies

At its narrowest point, the Strait of Hormuz measures just 21 miles (33 kilometers) wide, with shipping lanes only two miles wide in each direction. Despite these constrained dimensions, it carries an outsized share of the world's energy supplies, underscoring its immense strategic importance.

• Approximately one-fifth of global oil consumption passes through the Strait of Hormuz.
• More than 20 million barrels of crude oil, condensate, and refined fuels moved through the strait daily last year.
• Roughly 30% of all seaborne oil flows transit this route.
• Qatar sends almost all of its liquefied natural gas (LNG) exports through this passage.
• Major oil producers, including Saudi Arabia, Iran, Iraq, Kuwait, and the United Arab Emirates, rely heavily on this corridor to export crude, with much of it destined for Asian markets.

Energy analysts warn that even a short-term disruption could drive crude prices sharply higher. A closure lasting weeks rather than days could push oil well above $100 per barrel and send European natural gas prices back toward the crisis levels witnessed in 2022.

Limited Alternatives and Escalating Risks

Some Gulf producers have partial alternatives to bypass the Strait of Hormuz, but these are insufficient to fully mitigate the risks of a closure. Saudi Arabia can redirect some exports via its East-West pipeline to the Red Sea, while the UAE operates the Habshan–Fujairah pipeline, which bypasses Hormuz for a portion of its crude. Iraq maintains a northern pipeline through Turkey, though most of its exports still ship from Basra via the strait.

However, Kuwait, Qatar, and Bahrain remain entirely dependent on the Strait of Hormuz for their energy exports. Analysts emphasize that even with existing alternative pipelines, a full shutdown would significantly disrupt global energy supply chains.

Iran itself produces over 3 million barrels of crude per day and exports the majority of it—largely to China—via terminals such as Kharg Island in the northern Gulf. Any military strike on these facilities would further escalate the crisis, potentially triggering broader regional conflict.

Echoes of the 1970s Energy Shock

The current tensions have revived comparisons with the oil crises of the 1970s. In 1973–74, Arab producers imposed an embargo during the Yom Kippur War, leading to severe fuel shortages and soaring inflation worldwide. A second shock followed in 1979 after the Iranian Revolution drastically reduced output.

Analysts now caution that a prolonged closure of the Strait of Hormuz could create a disruption even more severe than those historical events, given today's higher global energy demand and tighter supply chains. Beyond oil, the strait is also crucial for trade in refined fuels, petrochemicals, and other commodities.

For countries like India, which exports significant volumes of rice and imports large quantities of Gulf crude, the fallout could extend well beyond energy markets, affecting broader economic stability. The central question remains the duration of any disruption: a brief flare-up might be absorbed by global markets, but a sustained blockade would have profound consequences for global inflation, shipping costs, and overall economic stability.
