Tensions escalate as Iran threatens to close the Strait of Hormuz

06/24/2025 / By Belle Carter

Iran, through Major General Kowsari of the National Security Commission, has threatened to close the Strait of Hormuz following U.S. strikes on its nuclear sites. The final decision, however, lies with the Supreme National Security Council and Ayatollah Ali Khamenei.
The Strait of Hormuz, a critical maritime chokepoint between Oman and Iran, is vital for global oil and LNG shipments. It has been a focal point of conflict, notably during the Iran-Iraq War’s Tanker War and in 2011 when Iran threatened closure due to sanctions.
The U.S. and its allies have historically responded to threats in the Strait of Hormuz with a show of force. During past tensions, the U.S. has deployed naval assets and initiated operations like Operation Sentinel to ensure the safety of maritime traffic.
Closure of the strait could lead to a sharp increase in oil prices, potentially reaching 120?120?130 per barrel, according to JPMorgan’s Natasha Kaneva. This would disrupt global oil markets, antagonize major buyers like China and force vessel rerouting around Africa, increasing costs and travel time.
Iran lacks the legal authority to close the strait, necessitating force or threats. The U.S. Fifth Fleet and other Western navies would likely respond forcefully to any blockage. Iran could use unconventional tactics, such as small boats, drones and missiles, to disrupt shipping without direct confrontation.

Critical maritime chokepoint, the Strait of Hormuz, is once again at the center of geopolitical tensions as Iran threatens to close it. The threat comes from Major General Kowsari, a senior member of the Iranian Parliament’s National Security Commission, who stated that the Parliament has concluded the strait should be closed. The final decision, however, rests with the Supreme National Security Council and Ayatollah Ali Khamenei.

The threat was issued in the wake of U.S. B-2 stealth bomber strikes on Iran’s key nuclear sites – Fordow, Natanz and Esfahan. The Strait of Hormuz, located between Oman and Iran, is a vital artery for global oil and liquefied natural gas (LNG) shipments.

The Strait of Hormuz has long been a focal point of regional and global tensions. During the 1980-88 Iran-Iraq War, the strait was a theater of conflict known as the Tanker War, where both sides attacked 451 vessels, significantly raising insurance costs and oil prices. In 2011, Iran threatened to close the strait in response to sanctions but ultimately did not follow through.

The United States and its allies have historically responded to threats against shipping in the Strait of Hormuz with a show of force. During the Tanker War, the U.S. Navy escorted vessels through the Gulf. In 2019, the U.S. dispatched an aircraft carrier and B-52 bombers to the region and initiated Operation Sentinel, which later evolved into the International Maritime Security Construct, involving ten other nations.

Potential consequences and legal and military considerations

The potential closure of the Strait of Hormuz would have immediate and severe consequences. According to JPMorgan’s chief commodity strategist, Natasha Kaneva, such an action could send oil prices into the 120?120?130 per barrel range. This would not only impact global oil markets but also antagonize China, the largest buyer of Iranian oil, which has used its veto power at the UN Security Council to shield Iran from Western-led sanctions.

Iran has no legal authority to halt traffic through the strait, so any closure would require the use of force or the threat of force. The U.S. Fifth Fleet and other Western navies patrol the area and would likely respond strongly to any attempt to block the strait. However, Iran could cause severe disruption without deploying warships, using small, fast patrol boats, drones and missiles to harass shipping.

The disruption of the strait would not only affect oil and LNG shipments but also force vessel operators to reroute traffic around the southern tip of Africa, a longer and more expensive journey. This was evident in June 2024, when the number of ships sailing through the Red Sea and Gulf of Aden was down about 70 percent compared to the average level of 2022 and 2023, according to Clarkson Research Services Ltd.

The crypto-based prediction market Polymarket has seen a sharp increase in the odds of a “Strait of Hormuz closure by July,” rising from roughly 15 percent before the U.S. strikes to as high as 60 percent earlier on Sunday, June 22. This reflects a significant repricing of geopolitical risk.

In the words of U.S. Secretary of State Marco Rubio, “If Iran closes the Strait of Hormuz, it will be another terrible mistake. It’s economic suicide for them if they do it and we retain options to deal with that.” The world waits to see if Iran will follow through on its threat or if cooler heads will prevail.
