UAE‑registered tanker explodes after striking Iranian mine near Hormuz Strait.

An oil tanker was reported to have caught fire and subsequently exploded in the southern part of the Strait of Hormuz after striking a naval mine, according to a statement issued by Iran’s Islamic Revolutionary Guard Corps (IRGC) on Friday. The incident occurred at approximately 13:20 local time near the Iranian coast, roughly 70 nautical miles from the strategic chokepoint that connects the Persian Gulf with the Gulf of Oman. The vessel, registered in the United Arab Emirates, was reportedly en route from the Gulf of Oman to a refinery in Saudi Arabia when the explosion unfolded. No crew members were immediately confirmed dead, but several were injured, and the tanker was later declared a total loss.

The Strait of Hormuz, a narrow waterway that is less than 21 kilometres wide at its narrowest point, is a linchpin of global energy transport. Roughly 20 % of the world’s crude oil passes through this stretch, making it one of the most heavily trafficked maritime corridors in the world. Iran, which borders the Gulf to the south, has long used its geographic position to exert influence over shipping lanes, and the deployment of naval mines has been a recurring tactic in its strategy to deter foreign vessels, particularly those of the United States and its allies. The mine that struck the tanker was reportedly laid by Iranian forces in the past months, a move that has raised alarm among international shipping companies and governments alike.

Iran’s position on the incident is that the mine was part of a defensive measure against what it describes as “foreign military intrusion.” In a brief statement, the IRGC said the tanker “unwittingly entered a minefield laid by the Iranian Armed Forces as a deterrent to hostile naval activity.” The Iranian government has repeatedly warned that its waters are “not a playground” for foreign warships and has threatened to use mines and other defensive assets to protect its maritime interests. In contrast, the United States and several Gulf Cooperation Council (GCC) states have called for a thorough investigation, stressing that the use of mines in international waters violates maritime law and poses an unacceptable risk to global trade. The U.S. Department of Defense has indicated that it will monitor the situation closely and has reiterated its commitment to ensuring the safety of commercial shipping in the region.

The broader context of the incident is one of escalating tensions in the Persian Gulf. In recent months, the region has seen a series of maritime confrontations, including the seizure of a Saudi tanker by Iranian forces and the deployment of U.S. naval vessels in the vicinity of the Strait. Sanctions imposed by the U.S. on Iranian oil exports have further strained the region’s economic stability, while the global community remains wary of any escalation that could disrupt the flow of petroleum. Shipping companies have issued warnings to reroute vessels around the Strait, and the International Maritime Organization has called for heightened vigilance among flag states.

For Taiwan, the incident underscores the fragility of the island’s energy security. Although Taiwan’s domestic energy consumption is primarily met through liquefied natural gas and renewable sources, it still imports a significant portion of its crude oil and refined products. A disruption in the Strait of Hormuz could lead to a sharp increase in global oil prices, which would ripple through Taiwan’s economy, affecting everything from manufacturing to transportation. Moreover, Taiwan’s semiconductor industry, which relies on a complex supply chain that spans the globe, could feel secondary impacts if shipping delays or cost increases strain logistics operations. In the wider region, the incident serves as a reminder that the stability of critical maritime chokepoints is essential for maintaining the flow of goods and capital across international borders.
