U.S. Central Command announced that American forces sank several Iranian ships, including 16 minelaying vessels, near the Strait of Hormuz amid reports that Tehran was seeking to mine the waterway, which is critical to global energy supplies [1]. President Donald Trump warned of 'military consequences ... at a level never seen before' if any mines were not removed from the Strait, stating in a Truth Social post: 'If for any reason mines were placed, and they are not removed forthwith, the Military consequences to Iran will be at a level never seen before. If, on the other hand, they remove what may have been placed, it will be a giant step in the right direction!' [1]. Trump later claimed that 10 inactive minelaying ships were sunk, with 'more to come' [1].
A CNN report indicated that Iran had started laying mines in the Strait of Hormuz, though not extensively, with sources citing 'a few dozen' mines laid in recent days [1]. Iran retains more than 80% of its small boats and minelayers and could lay hundreds of mines in the waterway if it chose to escalate [1]. CBS News reported that Iran 'may be getting ready' to deploy more naval mines using smaller craft capable of carrying two to three mines each [1]. Estimates of Iran's mine stock range from roughly 2,000 to 6,000 naval mines, though the exact figure is not publicly known [1].
The Strait of Hormuz handled approximately 13 million barrels of crude per day in 2025, representing about 31% of all seaborne crude flows, according to energy consulting firm Kpler [1]. Oil prices have spiked since the conflict began, with prices nearing $120 a barrel on Monday before coming down. U.S. WTI crude oil was last trading at $84.9 a barrel, while global benchmark Brent was at $88.9 per barrel [1]. Last week, oil supertanker costs in the Middle East reached their highest level on record, with major marine war risk providers scrapping coverage for vessels operating in the Persian Gulf [1].
The Robert Strauss Center for International Security and Law in Texas noted that mines would be 'beneficial' for Iran to use in the shipping lanes of the Strait of Hormuz, either for direct damage or as a deterrent, channeling ships into lanes more favorable to Iran [1]. A declassified CIA report from 2009 stated: 'The Iranians appear to have recognized the limitations of their mine warfare capability and have adopted a strategy in which a few mines or the threat of mining would be used to deter shipping.' The report added that Iran could use mines to raise insurance rates and discourage ships bound for Arab Gulf ports from entering the Persian Gulf, noting: 'such mining would be just as effective as a blockade' [1].
CONCLUSION
The sinking of Iranian minelayers by U.S. forces and the threat of further mining in the Strait of Hormuz have led to a spike in oil prices and record-high supertanker costs, with insurers withdrawing coverage for vessels in the region [1]. The situation remains tense, with both military and economic consequences likely if Iran escalates mine deployment [1]. The market impact is significant due to the Strait's role in global energy flows.
