The global economy is critically over-reliant on the Strait of Hormuz, a single maritime chokepoint for energy supplies, with no viable short-term alternatives. A prolonged closure, as analyzed in war scenarios, would be economically devastating, necessitating military force to reopen it, as there are no ways to circumvent it. This vulnerability is starkly exposed in a current extreme conflict scenario where the strait is closed, shipping is attacked, and regional energy infrastructure is targeted, despite which the Iranian government remains operational and committed to the closure.

Infrastructure Limitations and Logistical Challenges

Approximately 20% of the world's crude oil and natural gas supplies transit the Strait of Hormuz. Reducing this figure to improve energy security is possible but difficult. Currently, only two pipeline alternatives exist: Saudi Arabia's East-West Pipeline to the Red Sea and the UAE's Habshan-Fujairah Pipeline to the Gulf of Oman. With capacity upgrades, these could divert 5-7 million of the 20 million barrels per day traded through the strait. However, this diversion creates massive logistical challenges, as port infrastructure, personnel, tanker routes, and supporting logistics in new locations would all need to be developed to handle the extra volumes. Other global straits, like the Suez Canal and Bab al-Mandab, are already operating at capacity, creating additional bottlenecks.

Long-Term Strategic Alternatives and Costs

Building new pipeline infrastructure to bypass the strait is expensive and time-consuming. Potential routes, such as from Iraq through Turkey or a new pipeline through Jordan, face significant financial, geopolitical, and security hurdles, including exposure to cross-border attacks. However, Iran's broad regional attacks could spur Gulf countries to form alliances to finance such alternatives, potentially toward the Turkish Straits to access European and African markets, though this would require years of concentrated effort. Qatar faces a unique challenge, as avoiding Hormuz would mean building a new gas pipeline through Saudi Arabia and constructing new liquefaction facilities on the Red Sea coast, effectively abandoning its existing LNG export capacity.

Global Responses and Policy Tools

The international community, through the UN Security Council, has condemned Iran and emphasized that global energy security is linked to the strait's openness. In the short term, policymakers can only rely on releasing strategic petroleum reserves to moderate, but not reverse, oil price spikes, as evidenced by a 400-million-barrel release that failed to significantly lower prices near $100 a barrel. Long-term solutions—diversifying oil imports, electrifying transportation, and improving energy efficiency—take years to implement and offer no immediate relief. China exemplifies a multi-pronged long-term approach by diversifying import sources, leading in electric vehicle production, and relying on coal and nuclear power to reduce gas dependence, though it would still suffer serious economic pain from a prolonged closure.

Fundamental Constraints and Regional Risks

The situation is not analogous to past infrastructure retooling, like during the US shale boom. In the Middle East, almost all necessary infrastructure beyond the two existing pipelines would need to be built from scratch. Iran itself faces significant risk, as relocating its main oil processing center from Kharg Island to the Gulf of Oman would place it closer to its fields but leave it exposed to targeted attacks, with no safe alternate shipping route available. Ultimately, without physical ways to bypass the Strait of Hormuz, the world's only long-term alternatives are to source energy from elsewhere, reduce consumption, or build other energy sources, all of which are gradual processes that the current crisis may only serve to accelerate.
