What's happened
As of March 15, 2026, Iran has effectively closed the Strait of Hormuz amid ongoing conflict with the US and Israel, causing oil prices to surge above $100 per barrel. US President Donald Trump has urged China, France, Japan, South Korea, the UK, and others to send warships to secure the vital waterway. Iran’s new supreme leader, Mojtaba Khamenei, vows to keep the strait closed to pressure the US, while Tehran insists the strait remains open to non-enemy shipping.
What's behind the headline?
Strategic Importance of the Strait of Hormuz
The Strait of Hormuz is a chokepoint for about 20% of the world's oil supply, making its security vital for global energy markets. Iran’s control and partial closure of the strait is a strategic lever to exert economic pressure on the US and its allies.
Challenges of Securing the Strait
- The strait’s narrowness (21 nautical miles at its narrowest) and congested shipping lanes make military escort operations complex and risky.
- Iran’s use of drones, mines, and missiles poses a persistent threat to naval vessels and commercial shipping.
- Insurance premiums for ships transiting the strait have soared, deterring commercial traffic.
Trump’s Call for a Naval Coalition
President Trump’s appeal to major economies to send warships marks a shift from his earlier dismissive stance toward allied involvement. However, no country has publicly committed to this coalition, reflecting reluctance to escalate militarily.
Iran’s Position and Regional Dynamics
Iran maintains the strait is open to all except US and allied vessels, framing its actions as defensive. The new supreme leader, Mojtaba Khamenei, signals a prolonged closure to leverage negotiations.
Forecast and Implications
- Without a diplomatic breakthrough, the strait will remain a flashpoint, sustaining high oil prices and global economic instability.
- Military efforts to secure the strait will be costly and risk wider regional escalation.
- The situation underscores the fragility of global energy security and the limits of military solutions absent political dialogue.
What the papers say
Al Jazeera reports that Iran’s new supreme leader Mojtaba Khamenei has vowed to keep the Strait of Hormuz closed, while Iranian officials insist the strait remains open to non-enemy shipping. Trump’s calls for a naval coalition including China, France, Japan, South Korea, and the UK to secure the strait have so far met with no public commitments (Al Jazeera, March 15).
The New Arab highlights the surge in global oil prices by 40% due to Iran’s chokehold on the strait and notes Trump’s assertion that the US has destroyed 100% of Iran’s military capability, though Iran retains the ability to strike the waterway with drones and missiles (The New Arab, March 14).
The Independent and The Guardian detail Trump’s shifting tone toward the UK, from dismissing its involvement to urging it to send warships, reflecting tensions between the US and UK governments amid the conflict (The Independent, March 14; The Guardian, March 14).
Reuters and the NY Post emphasize Trump’s social media posts calling for international cooperation to keep the strait open and safe, while Iran’s military denies its capabilities have been destroyed and warns against US naval presence (Reuters, March 14; NY Post, March 14).
AP News provides expert analysis on the challenges of securing the strait, noting that military escorts require elimination of Iranian offensive installations and high-level intelligence, with insurance costs for shipping reaching prohibitive levels (AP News, March 11).

How we got here
The conflict began two weeks ago when the US and Israel launched strikes on Iran, killing its supreme leader. Iran responded by targeting ships in the Strait of Hormuz, a narrow passage critical for global oil trade, effectively blocking it. This has led to soaring oil prices and heightened global economic and security concerns.
