Despite the fragile ceasefire between the United States and Iran, the economic consequences of the Strait of Hormuz crisis continue to reverberate across global markets.
The disruption of maritime traffic through one of the world’s most strategically significant waterways has immobilised roughly one-fifth of global oil exports and a comparable share of liquefied natural gas shipments, while also constraining the movement of key industrial commodities, including aluminium, helium, and fertilisers.
The economic effects are already becoming apparent. Energy shortages have emerged in parts of East Asia and Australia, transport costs have risen sharply, and fuel markets remain highly volatile.
In the United States, gasoline prices have risen sharply, adding further inflationary pressure at a time when many economies remain vulnerable to supply-side shocks. If disruptions persist, the consequences are likely to extend beyond energy markets, affecting industrial production, trade flows, and broader patterns of economic growth.
The closure of the Strait of Hormuz has often been compared to the 1973 Arab oil embargo. While the analogy is useful, the current crisis differs in important respects. The oil embargo relied primarily on coordinated production decisions by exporting states. By contrast, the Hormuz crisis highlights the vulnerability of a critical maritime chokepoint through which a substantial share of global energy trade still flows.
The challenge is therefore not merely a matter of supply, but of infrastructure, geography, and strategic access.
Most importantly, recent events have shown that even advanced military capabilities may not be sufficient to ensure uninterrupted commercial navigation through the strait.
Regardless of how the current confrontation is ultimately resolved, policymakers should assume that the risk of future disruptions will remain a recurring feature of the regional security environment.
A Structural Vulnerability in the Global Economy
The central strategic lesson of the Hormuz crisis is that the international economy remains heavily dependent on a small number of critical transit corridors. Although globalisation has diversified sources of production and consumption, many supply chains still converge through a small number of maritime bottlenecks.
Iran has spent decades developing asymmetric capabilities specifically designed to threaten maritime traffic in the Gulf. Mines, drones, anti-ship missile systems, and naval swarm tactics provide Tehran with relatively low-cost tools capable of inflicting disproportionately high economic costs on its adversaries.
Recent events suggest that even limited disruption can create significant uncertainty across shipping companies, insurers, and commodity markets.
The significance of this development extends well beyond the Middle East. It raises broader questions about the resilience of the global trading system in an era marked by intensifying geopolitical competition, economic fragmentation, and growing strategic rivalry among major powers. Similar concerns increasingly surround other critical chokepoints, including the Bab el-Mandeb, the Suez Canal, the South China Sea, and even vital digital infrastructure, such as subsea communication cables.
For governments and markets alike, the issue is no longer whether such disruptions are possible, but how often they may occur and how effectively economies can absorb them.
The challenge facing policymakers is therefore not simply one of deterrence but of resilience.
Learning From the 1970s
The 1973 oil embargo prompted a far-reaching transformation of Western energy policy.
Strategic petroleum reserves were expanded, energy efficiency standards were strengthened, and governments sought to diversify suppliers and fuel sources. These measures did not eliminate vulnerability, but they significantly reduced the ability of individual producers to exert sustained economic pressure through supply restrictions. The response was ultimately successful not because it prevented future geopolitical crises, but because it reduced the systemic consequences of those crises. By creating redundancy, diversification, and flexibility, governments diminished any single actor’s capacity to leverage energy dependence for political gain.
Today’s challenge requires a similarly long-term response. The objective should not be to eliminate geopolitical risk—an unrealistic goal—but to reduce the economic and strategic consequences of future disruptions. This requires moving beyond crisis management towards resilience-building.
Diversifying Routes and Strengthening Strategic Infrastructure
One priority should be to expand alternative export infrastructure across the Gulf region.
Existing pipeline networks in Saudi Arabia and the United Arab Emirates already offer partial alternatives to Hormuz-bound shipping. Expanding these networks—and integrating additional Gulf producers—would reduce dependence on a single maritime corridor and improve the reliability of global energy flows.
Parallel investments in rail, logistics, and port infrastructure could further enhance regional connectivity and offer alternatives for moving non-energy commodities. International financial institutions, development agencies, and strategic partners could play an important role in supporting these projects.
The United States, together with its allies, should view these investments not merely as commercial initiatives but as strategic infrastructure projects that strengthen collective economic security. Financing mechanisms through export-credit agencies, development finance institutions, and multilateral partnerships could support the construction of alternative routes while strengthening relationships with key regional partners.
Such initiatives would also reinforce a broader principle increasingly central to twenty-first-century statecraft: resilience is built not only on military capabilities but also on the physical and economic architecture underpinning global commerce.
Domestic Resilience and Economic Security
At home, major consuming economies should strengthen their capacity to absorb external shocks. Strategic reserves remain a critical tool, but governments should also consider investing in storage capacity, infrastructure modernisation, and supply-chain diversification.
In the United States, this includes addressing vulnerabilities arising from the geographic concentration of refining capacity and transport networks. Expanding domestic energy infrastructure, modernising distribution systems, and improving inter-regional connectivity would help mitigate the impact of future supply disruptions. More broadly, policymakers should increasingly regard economic resilience as a core element of national security. The distinction between economic and security policy has become increasingly blurred.
Supply chains, logistics networks, energy systems, and critical infrastructure now occupy the same strategic space that was once reserved primarily for military considerations.
The Energy Transition as a Strategic Imperative
Over the longer term, the most effective means to reduce exposure to Hormuz-related disruptions may be to reduce dependence on hydrocarbons.
Energy transition policies are often debated primarily through the lens of environmental sustainability. Yet recent events underscore their equally important geopolitical dimension. Expanding renewable energy generation, electrifying transport, investing in advanced storage technologies, and diversifying energy sources can reduce exposure to disruptions in global oil and gas markets while enhancing economic resilience.
This does not imply abandoning conventional energy production. Rather, it suggests adopting a broader conception of energy security—one that emphasises diversity, redundancy, flexibility, and resilience across the energy system. An effective energy strategy should therefore combine support for reliable domestic hydrocarbon production with accelerated investment in emerging energy technologies.
The objective is not merely decarbonisation; it is strategic diversification.
The Real Challenge Is Not Iran
A narrow focus on Iran risks obscuring the broader lesson from the Strait of Hormuz crisis.
The principal vulnerability exposed by the conflict is not the behaviour of a single state, but the international economy’s continued dependence on a small number of critical chokepoints through which energy, commodities, and trade must flow. Even if military operations ultimately succeed in restoring navigation through the strait, they will not eliminate the structural conditions that made the crisis possible.
Future disruptions—whether caused by interstate conflict, terrorism, cyberattacks, political instability, or climate-related events—could have similar consequences elsewhere in the global trading system. The strategic question for policymakers is therefore not how to prevent every future crisis, but how to ensure that future crises do not produce disproportionate economic and political effects.
The history of energy security shows that resilience is ultimately more sustainable than deterrence alone. The response to the oil shocks of the 1970s was not simply to protect oil supplies through military means. It was to diversify sources, improve efficiency, build strategic reserves, and reduce structural vulnerabilities. Those measures fundamentally altered the balance of power between producers and consumers.
The current crisis demands a comparable response. Investments in alternative transport corridors, expanded regional infrastructure, diversified supply chains, strategic reserves, and energy innovation should be understood not merely as economic policies but as instruments of national and international security.
From Deterrence to Resilience
The Strait of Hormuz crisis may ultimately be remembered less for its immediate economic costs than for the strategic lesson it provides.
It has highlighted the extent to which global prosperity remains dependent on a handful of critical transit corridors and exposed the limitations of relying solely on military power to secure them. Even if commercial traffic eventually resumes, the assumption that Hormuz will remain permanently secure can no longer be taken for granted.
Policymakers should therefore focus not only on reopening the strait but also on reducing the global economy’s vulnerability to future disruptions.
The broader challenge is not merely Iran.
It is the persistence of structural dependencies within the international economic system. Building resilience to those dependencies—through infrastructure investment, diversified supply chains, strategic reserves, and accelerated energy innovation—will be essential to managing future geopolitical shocks without triggering major economic crises.
In the decades ahead, the countries best positioned to navigate an increasingly uncertain international environment will not necessarily be those with the greatest military power. They will be those that build the most resilient economies, the most adaptable energy systems, and the most diversified networks of trade and infrastructure.
The ultimate lesson from Hormuz is therefore not about the Gulf.
It concerns the future of globalisation itself.
The defining strategic challenge of the twenty-first century may not be securing every chokepoint indefinitely, but rather creating an international economic system in which no single chokepoint has the capacity to disrupt global prosperity on a systemic scale.
