Iran is escalating the war by placing explosive mines along a key oil route. Here are the risks.
Iran’s Strategic Move in the Strait of Hormuz
Iran has taken a bold step in the ongoing conflict by deploying explosive mines across the Strait of Hormuz, a vital artery for global oil trade. This action highlights the country’s reliance on unconventional tactics, even as it faces sustained pressure from U.S. and Israeli strikes.
A Critical Waterway Under Threat
The strait, through which approximately one-fifth of the world’s oil supply flows, is now a focal point of strategic tension. Despite being outmatched in firepower and resources by the U.S. and Israel, Iran retains a significant advantage by controlling this narrow passage. The placement of mines further complicates navigation, deterring commercial vessels and signaling a new phase in the conflict.
Minelayer Operations and Unverified Claims
According to intelligence sources, Iran has laid several dozen mines in recent days, though the scale is not extensive. A U.S. official noted that Tehran still operates around 80-90% of its small boats and minelayers, contradicting former President Donald Trump’s assertion that the country has “no navy.” Meanwhile, UKMTO, a British maritime security agency, has stated there is “no confirmed evidence of mine deployment or detonation” in the region.
“If Iran has put out any mines in the Hormuz Strait, and we have no reports of them doing so, we want them removed, IMMEDIATELY!”
Trump’s social media post emphasized the urgency of clearing mines, warning that failure to act could lead to “consequences at a level never before seen.” However, he also acknowledged that removing “what may have been placed” would be “a giant step in the right direction.”
Types of Mines and Their Impact
Iran’s arsenal includes various mine types, such as limpet mines attached by divers, moored mines that detonate on contact, and bottom mines that trigger explosions when detecting nearby ships. These weapons, combined with suicide boats and shore-based missiles, have been described as creating a “gauntlet” of threats in the strait.
Recent Attacks on Vessels
The dangers of the strait were underscored on Tuesday when Iranian forces targeted the Thai-flagged bulk carrier Mayuree Naree, causing an explosion in its engine room. Three crew members were missing, according to Thai authorities. The same day, the Liberian-flagged Express Rome was also hit by Iranian projectiles, demonstrating the escalating risks for maritime traffic.
U.S. Response and Mine Sweeping Challenges
U.S. Central Command reported destroying 16 Iranian minelayers near the strait, but it did not confirm any mines were neutralized. The U.S. Navy’s minesweeping capabilities have weakened, with the last dedicated minesweeper decommissioned in September 2025. Now, littoral combat ships are tasked with this role, despite their reputation for technical issues.
Economic Consequences of the Closure
Analysts warn that the strait’s closure could disrupt oil shipments, leaving 15 million barrels per day of crude and 4.5 million barrels per day of refined oil stranded in the Gulf. As storage capacities reach their limits, the global economy faces potential volatility. Navigating the strait during peacetime requires precision, but the addition of mines now heightens the peril for ships attempting passage.
