Two Tankers Attacked in Strait of Hormuz, Triggering Global Oil Supply Fears

The Islamic Revolutionary Guard Corps (IRGC) of Iran confirmed on Thursday local time that two oil tankers had exploded while passing through the Strait of Hormuz. This sudden incident immediately triggered volatility in global energy markets and further escalated tensions in the Persian Gulf region. The cause of the explosions remains under investigation, while the extent of the damage to the vessels and the safety of the crews remain a primary focus of the international community. The incident has already caused short-term fluctuations in oil prices.

The Strait of Hormuz is the world’s most critical energy artery, through which approximately one-fifth of the world’s daily oil supply passes; its strategic importance is self-evident. As a major power in West Asia, Iran’s territory spans both the Persian Gulf and the Gulf of Oman. While the historic Persian civilization once created a glorious legacy, modern geopolitical maneuvering between Iran and Western nations has frequently turned these waters into a frontline for confrontation. Over the past few years, there have been multiple instances of ships sustaining unexplained damage or being seized in the area, often reflecting the sharp conflicts between Iran and the United States and its allies regarding nuclear deal negotiations, sanctions pressure, and the struggle for regional influence.

From the perspective of all parties involved, Iranian authorities have long maintained that stability in the Strait of Hormuz should be upheld by regional countries, frequently warning that the intervention of foreign naval forces undermines regional security. Conversely, Western nations led by the United States insist that the waterway must remain open for international freedom of navigation and have sought to secure energy transport through joint naval escort missions. Whenever conflict erupts in this region, international oil prices often react sharply, highlighting the global energy supply chain's high dependency on this narrow waterway and the ripple effects of political instability on the global economy.

Regional countries and international organizations are currently monitoring the situation closely to prevent the conflict from escalating into a larger military confrontation. While nations typically utilize diplomatic channels to address such incidents, the lack of mutual trust between Iran and the Western camp, combined with the dense military deployments in the Persian Gulf, means that any minor miscalculation could lead to unpredictable consequences. The international community is urging all parties to remain calm and is calling for a fair and transparent investigation into the explosions to determine whether they were caused by technical failure, sabotage, or other geopolitical factors.

For Taiwan, although it has no direct territorial or military conflict with Iran, its energy supply is heavily reliant on imports, with a significant portion of its crude oil originating from the Middle East. Any unrest in the Strait of Hormuz directly affects Taiwan’s energy import routes and costs. Furthermore, given the highly interconnected nature of global supply chains, a deterioration of the situation in the Persian Gulf resulting in a surge in global energy prices would have a direct impact on domestic inflation, manufacturing costs, and export competitiveness in Taiwan. This incident serves as a reminder that as Taiwan pursues economic development and energy transition, it must remain vigilant regarding risks at distant, critical geopolitical chokepoints to enhance the resilience of its national energy security.
