The Strait of Hormuz serves as a critical global shipping route, with about 20 per cent of the world’s oil and gas passing through it. A blockade would likely disrupt global energy markets and significantly raise fuel prices. However, oil prices have declined more than 10 per cent since US strikes on Iran's nuclear infrastructure, as markets responded to the absence of any actual shipping disruption.
Strait of Hormuz remains open despite Iranian preparationsShortly after the US airstrikes on three Iranian nuclear sites on June 22, Iran’s parliament backed a measure to block the Strait of Hormuz. The vote was non-binding, and the authority to enforce a closure rests with Iran’s Supreme National Security Council. Iran has frequently issued threats to shut the strait, but it has never acted on them.Reuters could not determine the exact timing of the mine loading activity or whether the mines have since been removed. The officials declined to specify how the US confirmed the mines were loaded, but such intelligence is typically gathered via satellite surveillance, human intelligence sources, or a combination of both.
A White House official credited the administration’s efforts for maintaining navigational access through the region. “Thanks to the president’s brilliant execution of Operation Midnight Hammer, successful campaign against the Houthis, and maximum pressure campaign, the Strait of Hormuz remains open, freedom of navigation has been restored, and Iran has been significantly weakened,” the official said.

The Pentagon and the Iranian mission to the United Nations did not immediately respond to requests for comment.

US officials have not ruled out the possibility that Iran’s mine-loading activity was a strategic deception. The officials noted that the move may have been designed to pressure the US or demonstrate readiness without actual intent to close the strait.
Iran could also have been making logistical preparations in anticipation of a potential future order. The Strait of Hormuz, bordered by Iran and Oman, connects the Persian Gulf to the Gulf of Oman and the Arabian Sea. At its narrowest, the strait is 21 miles (34 kilometers) wide, with two-mile-wide shipping lanes in either direction.
Key oil exporters, Saudi Arabia, the United Arab Emirates, Kuwait, Iraq, and major LNG exporter Qatar all rely on the strait for shipping. Iran itself exports most of its crude through the passage, which could complicate any decision to disrupt it. Still, the US Defense Intelligence Agency estimated in 2019 that Iran possessed more than 5,000 naval mines, which could be deployed using high-speed boats.
The US Fifth Fleet, based in Bahrain, is tasked with ensuring the security of maritime traffic in the region. The Navy had temporarily withdrawn all mine countermeasure ships from Bahrain prior to the US strikes on Iran, citing the potential risk of retaliatory attacks.
