Iran is escalating the war by placing explosive mines along a key oil route. Here are the risks.
Iran’s Strategic Move: Mines in the Strait of Hormuz
The Strait of Hormuz, a vital artery for global oil trade, has become a focal point of escalating tensions as Iran deploys mines to disrupt maritime traffic. Despite being outgunned and outspent by the US and Israel, Tehran leverages its control over this narrow waterway to assert influence. The maneuver is a clear signal of its intent to challenge dominance in the region, even as it faces relentless airstrikes.
Asymmetric Tactics and Naval Capabilities
Iran’s strategy relies on asymmetric warfare, using limited resources to create significant obstacles for adversaries. Reports indicate the country has placed a few dozen mines in the strait, according to US intelligence sources. While not an overwhelming force, this action underscores Iran’s ability to maintain 80% to 90% of its small boats and minelayers, refuting claims that it has “no navy” as previously stated by former President Donald Trump.
“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!”
The UKMTO, a British maritime security organization, has noted that “there remains no confirmed evidence of mine deployment or detonation” in the strait. However, Iran’s arsenal includes around 5,000 to 6,000 naval mines, with varieties such as limpet mines, moored mines, and bottom mines, each designed to target vessels in different ways.
Recent Attacks and Escalation
The strategic importance of the strait was highlighted by attacks on two vessels. On Tuesday, the Islamic Revolutionary Guard Corps (IRGC) intercepted a Thai-flagged bulk carrier, Mayuree Naree, and struck it, causing damage to its engine room. Thai authorities reported three crew members missing. Earlier that day, a Liberian-flagged ship, Express Rome, was also targeted by Iranian forces.
US Central Command confirmed the destruction of 16 Iranian minelayers near the strait, though it did not specify any mines were removed. This leaves the waterway vulnerable, as the mines may already be in place. Critics argue that the US Navy’s minesweeping capabilities have diminished, with the last dedicated minesweeper decommissioned in September 2025. Littoral combat ships now handle the task, though their reliability has been questioned.

Global Economic Implications
Should the strait remain closed, the economic repercussions could be severe. Analysts estimate that 15 million barrels per day of crude oil and 4.5 million barrels per day of refined products are trapped in the gulf. Storage facilities are rapidly filling, heightening the risk of supply chain disruptions. Navigating the strait, even in peacetime, requires precision due to its narrow passage and heavy traffic. The addition of mines complicates this further, making recovery efforts more challenging.
Trump’s proposal to escort ships through the strait aims to counter these threats, but it involves exposing naval assets to potential attacks. The move could shield oil shipments but lacks a clear strategic edge in the broader conflict. As the situation evolves, the strait’s closure may force a reckoning with the global economy’s reliance on this critical route.
