Strait of Hormuz Game Escalates: Sword of Damocles Over Global Supply Chain
Introduction
The Strait of Hormuz, a narrow waterway connecting the Persian Gulf and the Arabian Sea, carries about one-third of global oil seaborne trade and has long been a focal point of great power games and geopolitical conflicts. Recently, as US-Iran confrontation over passage fees and military actions continues to escalate, the International Maritime Organization (IMO) has rarely published detailed evacuation procedures, marking a slide from diplomatic friction to a high-risk threshold. This dynamic not only affects security nerves in the Middle East but also profoundly impacts global supply chain expectations, becoming a core issue of close international concern.
1. Strategic Position of the Strait of Hormuz and Current Tensions
At its narrowest point, the Strait of Hormuz is only about 33 kilometers wide, yet it controls the throat of global energy transportation. About 20% of global oil consumption and an even higher share of liquefied natural gas pass through the strait daily. Any disruption to passage through the strait will directly trigger sharp fluctuations in international oil prices and transmit through the supply chain to manufacturing, logistics, and even end-consumer markets.
Recently, the United States has strengthened sanctions against Iran, demanding further compression of its oil exports, while trying to control passage rights through military deterrence. Iran has responded tit-for-tat, conducting multiple military exercises and threatening to increase the "passage fee" or impose a blockade as a countermeasure. Military deployments near the strait have significantly increased on both sides, with frequent friction incidents, raising the navigation risk for merchant ships in the area to the highest level in years.
2. IMO Response: Deep Meaning Behind Evacuation Details
Facing the increasingly severe security situation, the IMO quickly moved to publish detailed evacuation procedures for the Strait of Hormuz and surrounding waters. The procedures are not simple administrative instructions but a comprehensive plan covering merchant ship emergency routes, crew safety, flag state responsibilities, and regional coordination.
The procedures specify the alternative routes, communication frequencies, assembly points, and priority evacuation order that merchant ships must follow in the event of military conflict escalation or regional blockade. At the same time, the IMO calls on coastal states and major shipping nations to establish emergency communication mechanisms to avoid accidental conflicts due to misjudgment. This move reflects the international community's widespread concern about the deteriorating situation and indicates that the window for peaceful resolution is narrowing. On a deeper level, the IMO's intervention aims to prevent the passage issue from evolving into a systemic global shipping crisis, but the procedures themselves cannot eliminate geopolitical contradictions; they only serve as the last safety net.
3. Essence of US-Iran Game: Passage Fees, Military Presence, and Strategic Interests
On the surface, the dispute between the US and Iran over passage fees is a direct clash of economic interests. Iran has long asserted its jurisdiction over the Strait of Hormuz and attempts to impose a "transit fee" or use its geographical advantage to restrict passage in exchange for international concessions on its economic interests. The US insists that the strait is international waters, upholds the principle of freedom of navigation, and relies on the Fifth Fleet to maintain its dominance.
But the reality goes far beyond that. The military action game reflects deeper strategic intentions on both sides. The US aims to strengthen its military presence to cut off Iran's key leverage for countering external pressure; Iran tries to use the strait as a strategic bargaining chip to force concessions on issues such as the nuclear deal and sanctions. Neither side is willing to step back first, leading to a dangerous stalemate. This zero-sum game model not only puts neighboring countries in a dilemma but also makes the global shipping industry bear huge uncertainty risks.
4. Chain Impacts on Global Supply Chain and Market Expectations
The tensions in the Strait of Hormuz have already significantly negatively affected global supply chain expectations, mainly in the following aspects:
First, expectations of soaring energy costs. The market generally expects that if passage is blocked, international oil prices may break through 150 USD per barrel in the short term, pushing up costs in global manufacturing, transportation, and chemical industries, accelerating inflationary pressure. Second, shipping insurance costs surge. Multiple insurance companies have listed the area as a war risk zone, raising transit premiums for merchant ships several times, further increasing trade costs. Third, alternative routes and inventory adjustments. Some shipping companies have begun evaluating alternative routes such as bypassing the Cape of Good Hope, but this will significantly extend transit time, with Asia-Europe routes potentially increasing by 10-14 days. Fourth, long-term restructuring of corporate supply chains. This crisis further strengthens the willingness of multinational enterprises to diversify supply chains, promoting a reduction in reliance on single routes and accelerating regional and nearshore layouts.
From a market expectation perspective, investors have incorporated geopolitical risk factors into asset pricing models, increasing demand for safe-haven assets like gold and USD, while sectors dependent on imports and exports in stock markets face pressure. When formulating monetary policy, many central banks have begun to incorporate this uncertainty into inflation and growth forecasts.
5. Future Direction and Role of the International Community
Currently, there is no clear sign of a cooling-off in the Strait of Hormuz crisis. In the short term, diplomatic mediation remains the main path, with multiple forces including the United Nations, the European Union, and regional powers attempting to mediate. However, given the strong positions of both the US and Iran, reaching substantial compromise is extremely difficult. In the medium to long term, the situation in the strait may go through four phases: first, military friction continues but does not escalate into full conflict; second, local blockade and small-scale clashes lead to shipping disruption; third, international intervention forms a temporary safe passage mechanism; fourth, long-term confrontation under normalized high-risk conditions.
The international community should fully leverage platforms like the United Nations and IMO to promote the establishment of a multilateral security framework that includes Iran, clarifying the rights and obligations of all parties, and weakening confrontational emotions through economic cooperation and energy security as ties. After all, the fate of the Strait of Hormuz is not just about the Middle East but about the world.
Conclusion
The tensions in the Strait of Hormuz are like a prism, refracting the brutal game of great power geopolitics and reflecting the vulnerability of the global supply chain in the face of extreme risks. The evacuation procedures published by the IMO are a heavy warning bell, reminding the world that the safety of passage through the strait, a matter affecting billions of people, must be taken seriously. Only through rational dialogue and multilateral cooperation can this energy lifeline be prevented from becoming a fuse for global economic turmoil. Before the storm comes, the international community still has an opportunity to strive for the last window of peace.
