Iran Announces Indefinite Closure of Strait of Hormuz, Triggering Global Concern

The Iranian Revolutionary Guard Corps (IRGC) Navy has announced the indefinite closure of the Strait of Hormuz, claiming that it has opened fire on two vessels for utilizing unauthorized routes. This incident has triggered significant international concern, as the Strait of Hormuz serves as one of the world's most critical maritime chokepoints, through which approximately 20% of global oil production is transported.

The IRGC Navy, established in 1985, operates alongside the regular Iranian Navy with distinct strategies, training systems, and equipment structures. The force prioritizes asymmetric naval warfare, utilizing small, high-speed attack craft, anti-ship missiles, naval mines, and hit-and-run tactics. The IRGC Navy also functions as a de facto coast guard and maintains several marine units, including a special operations force known as the IRGC Navy Special Force.

The maritime strength of the IRGC Navy is substantial; reports indicate the force comprises 55,000 personnel and 33,000 vessels, with an operational reach extending from the Persian Gulf to Dar es Salaam and Zanzibar in Tanzania. This vast maritime presence grants the IRGC Navy significant influence in the region.

The decision to close the Strait of Hormuz may stem from concerns regarding the regional security climate. In recent years, tensions in the area have escalated, and Iran’s relations with other nations have become increasingly complex. The IRGC Navy's decision could impact global oil markets, thereby affecting energy supplies and economies worldwide.

The actions of the IRGC Navy have drawn international scrutiny. Governments and international organizations are closely monitoring the situation and calling on all parties to exercise restraint and rationality. The IRGC Navy’s decision has further complicated and sensitized the situation in the region, necessitating collective efforts to maintain regional stability and security.

For Taiwan, this event carries indirect consequences for its energy supply and economy. As a significant participant in the global oil market, Taiwan faces the prospect of rising oil prices due to the closure of the Strait of Hormuz, which could impact its energy costs and economic development. Consequently, the situation requires Taiwan to pay closer attention to regional developments to safeguard its energy security and economic interests.
