霍尔木兹海峡的战略地位
霍尔木兹海峡位于伊朗和阿曼之间,连接波斯湾与阿曼湾,是全球石油和天然气运输的关键咽喉。据美国能源信息署(EIA)数据,2025年每天约有2100万桶原油和凝析油通过这一水道,占全球海运石油贸易量的三分之一以上。此外,全球约四分之一的液化天然气(LNG)贸易也经由此地。
海峡最窄处仅约33公里,且可通行航道更为有限,实际可用宽度约为3公里的两条分道通航航道。这种天然的地理限制使得海峡极易受到封锁威胁。沿岸的伊朗、阿曼和阿联酋三国在海峡区域均有军事部署,其中伊朗的军事存在最为密集。伊朗在海峡北岸的格什姆岛和霍尔木兹岛上部署了大量反舰导弹阵地和雷达设施。
2026年的安全挑战
2026年上半年,霍尔木兹海峡的安全形势急剧恶化。除了美伊直接军事对峙外,也门胡塞武装在红海和亚丁湾的袭击行动也在间接影响波斯湾地区的航运安全。2026年1-5月,霍尔木兹海峡及周边海域发生了17起安全事件,包括无人机侦察、快艇逼近商船和电子干扰等。
对商船的最大威胁来自水雷。伊朗拥有数千枚各型水雷,理论上可以在数小时内封锁海峡。虽然国际扫雷力量长期在海峡区域驻扎,但面对大量布设的水雷,完全清除需要数周甚至数月时间。2026年5月,一艘巴拿马籍油轮在海峡入口处疑似触碰水雷受损,虽未造成人员伤亡和原油泄漏,但事件本身加剧了航运业的恐慌情绪。
航运保险成本飙升
地缘政治风险直接反映在航运保险成本上。2026年上半年,途经霍尔木兹海峡的船舶战争险保费较2025年同期上涨了280%。一艘VLCC(超大型油轮)单次通过海峡的战争险保费已从2024年的15万美元飙升至57万美元。部分保险公司甚至暂停了对波斯湾航线的承保业务。
保险成本的飙升直接推高了全球石油运输成本。据航运经纪公司克拉克森的数据,2026年6月中东至亚洲航线的VLCC运费较年初上涨了85%。运费上涨最终传导至终端消费者,每升汽油的运输成本增加约0.03-0.05美元。对于日进口石油超过1000万桶的亚洲经济体而言,这意味着每年数十亿美元的额外支出。
替代运输路线的开发
霍尔木兹海峡的风险促使各国加速开发替代石油运输路线。沙特阿拉伯的东西原油管道(Petroline)是目前最重要的替代通道,全长1200公里,从东部省油田延伸至红海岸边的延布港,日输送能力为500万桶。如果海峡被封锁,沙特可以将大部分石油出口转向红海方向。
阿联酋的阿布扎比原油管道(ADCOP)也提供了绕过海峡的选项,从哈布尚油田通往富查伊拉港,日输送能力150万桶。此外,伊拉克正在扩建从基尔库克至土耳其杰伊汉港的管道。但专家指出,所有替代路线的总运力不到海峡运量的一半,短期内无法完全替代霍尔木兹海峡的运输功能。
国际合作与能源安全的未来
维护霍尔木兹海峡的通行自由是国际社会的共同利益。美国第五舰队长期驻扎巴林,负责维护波斯湾和霍尔木兹海峡的航行自由。英国、法国、日本等国也在该区域部署了海军力量。2019年成立的国际海事安全联盟(IMSC)目前有12个成员国,协调海峡区域的护航和巡逻行动。
然而,军事手段无法从根本上解决海峡安全问题。各方呼吁通过外交途径降低紧张局势,建立包含所有沿岸国和主要利益攸关方在内的多边安全对话机制。中国提出的"波斯湾安全倡议"主张通过对话协商构建地区安全架构,得到了多个国家的积极响应。长远来看,加速能源转型、降低对化石燃料的依赖,才是从根本上化解霍尔木兹海峡安全风险的战略路径。
The Strategic Position of the Strait of Hormuz
The Strait of Hormuz, located between Iran and Oman, connects the Persian Gulf with the Gulf of Oman and serves as the critical chokepoint for global oil and natural gas transportation. According to the US EIA, approximately 21 million barrels of crude oil and condensate passed through this waterway daily in 2025, accounting for over one-third of global seaborne oil trade. Additionally, about one-quarter of global LNG trade transits through this passage.
The strait's narrowest point is only about 33 kilometers wide, with navigable channels even more limited—effectively two traffic separation scheme lanes of about 3 kilometers each. This natural geographic limitation makes the strait highly vulnerable to blockade threats. The coastal states of Iran, Oman, and the UAE all have military deployments in the strait area, with Iran's military presence being the densest. Iran has deployed extensive anti-ship missile batteries and radar installations on Qeshm Island and Hormuz Island along the strait's northern shore.
2026 Security Challenges
In the first half of 2026, the security situation in the Strait of Hormuz deteriorated sharply. Beyond direct US-Iran military confrontation, Houthi attacks in the Red Sea and Gulf of Aden were indirectly affecting shipping safety in the Persian Gulf region. Between January and May 2026, 17 security incidents occurred in and around the Strait of Hormuz, including drone surveillance, fast boat approaches to merchant vessels, and electronic interference.
The greatest threat to merchant shipping comes from mines. Iran possesses thousands of mines of various types and could theoretically blockade the strait within hours. Although international mine countermeasure forces have long been stationed in the strait area, fully clearing a large-scale mine deployment would take weeks or even months. In May 2026, a Panama-flagged tanker was damaged by a suspected mine near the strait entrance—no casualties or oil spills resulted, but the incident intensified shipping industry anxiety.
Soaring Shipping Insurance Costs
Geopolitical risk is directly reflected in shipping insurance costs. In the first half of 2026, war risk premiums for vessels transiting the Strait of Hormuz increased 280% compared to the same period in 2025. The war risk premium for a single VLCC transit through the strait has surged from $150,000 in 2024 to $570,000. Some insurers have even suspended coverage for Persian Gulf routes entirely.
Soaring insurance costs directly inflate global oil transportation costs. According to shipbroker Clarksons, VLCC freight rates on the Middle East-Asia route surged 85% in June 2026 compared to the beginning of the year. Freight increases ultimately pass through to end consumers, adding approximately $0.03-0.05 per liter to gasoline transportation costs. For Asian economies importing over 10 million barrels daily, this means billions of dollars in additional annual expenditure.
Development of Alternative Transport Routes
Hormuz Strait risks are accelerating development of alternative oil transport routes. Saudi Arabia's East-West Pipeline (Petroline) is currently the most important alternative corridor—1,200 kilometers long, running from Eastern Province oil fields to the Red Sea port of Yanbu, with a daily capacity of 5 million barrels. If the strait were blockaded, Saudi Arabia could redirect most oil exports toward the Red Sea.
The UAE's Abu Dhabi Crude Oil Pipeline (ADCOP) also provides a strait-bypass option, running from Habshan oil field to Fujairah port with 1.5 million barrels per day capacity. Additionally, Iraq is expanding its pipeline from Kirkuk to Turkey's Ceyhan port. However, experts note that the combined capacity of all alternative routes is less than half the strait's throughput, making it impossible to fully replace the Hormuz Strait's transport function in the short term.
International Cooperation and the Future of Energy Security
Maintaining freedom of navigation through the Strait of Hormuz is a shared interest of the international community. The US Fifth Fleet, based in Bahrain, has long been responsible for maintaining navigational freedom in the Persian Gulf and Strait of Hormuz. The UK, France, Japan, and other nations have also deployed naval forces in the region. The International Maritime Security Construct (IMSC), established in 2019, currently has 12 member nations coordinating escort and patrol operations in the strait area.
However, military means alone cannot fundamentally resolve strait security issues. All parties call for diplomatic approaches to reduce tensions and establish multilateral security dialogue mechanisms involving all coastal states and major stakeholders. China's 'Persian Gulf Security Initiative,' advocating construction of a regional security architecture through dialogue and consultation, has received positive responses from multiple nations. In the long term, accelerating energy transition and reducing dependence on fossil fuels is the strategic path to fundamentally resolving Hormuz Strait security risks.
