The Strait of Hormuz isn’t a regional risk; it’s a global system failure

When tensions flare in the Middle East and the Strait of Hormuz comes under pressure, it is easy to dismiss it as a regional crisis, another distant geopolitical flashpoint. But that framing is dangerously incomplete. What appears localized is, in fact, a real-time stress test of a tightly coupled global system, one in which disruption at a single chokepoint can reverberate across economies, industries, and households worldwide.

The Strait is not just a geographic corridor. It is a critical node in the global energy system. Its disruption does not simply create localized instability. It exposes how close the global system operates to its limits.

Cambodia provides a clear example of this reality. Despite being thousands of miles from the Persian Gulf, it feels the impact of instability in the Strait of Hormuz quickly and unevenly. As fuel prices rise, so do the costs of transport, food, distribution, electricity generation, and production. For many businesses and households, the impact is direct and unavoidable.

In Cambodia, this vulnerability is not abstract. It is lived. Poorer households spend a disproportionate share of their income on energy-intensive goods such as food and transport. When oil prices rise, fertilizer becomes more expensive, transport costs increase, and margins shrink across the supply chain. A rice farmer in Prey Veng feels it in input costs. A vendor in Phnom Penh feels it in declining purchasing power.

Cambodia is not unique in its exposure, but it is more immediately affected. It experiences the shock sooner and more visibly, revealing dynamics that are present, if less visible, in more advanced economies. Geography no longer protects. It only postpones the impact. The conflict has already pushed oil prices higher and introduced sustained volatility into global energy markets, raising costs for transportation, fertilizer, food, and other essentials.

The myth of distance in a connected world

The modern global economy rests on a paradox. It has never been more integrated, yet it continues to operate as though risks are contained within borders.

The Strait of Hormuz is the world’s most critical oil chokepoint. Approximately 20 million barrels of oil and petroleum products pass through it each day, accounting for a substantial share of global seaborne energy trade. It is also a major artery for liquefied natural gas, particularly from Qatar. Severe disruption in the Strait would place pressure on electricity and heating systems across multiple regions.

Capacity on alternative routes is limited. When the Strait’s stability is constrained, the effects are not confined to the Middle East. They ripple outward through energy markets, shipping routes, and global supply chains.

For countries like Cambodia, which rely heavily on imported fuel, these effects are immediate and visible. Price increases are felt at the pump and in the most vulnerable communities. The same dependencies exist elsewhere. Advanced economies may have more sophisticated financial systems or larger reserves, but they are not immune. They are simply better at absorbing shocks. Until they are not.

The notion that some economies are insulated from global disruptions is not a reflection of reality. It is a reflection of privilege.

We witnessed a similar dynamic during the pandemic, which I explore in my book Viral Sovereignty and the Political Economy of Pandemics. Crises do not create vulnerabilities. They reveal them. The Strait of Hormuz has not introduced risk into the global system. It has exposed the risks already embedded in it.

The hidden costs of efficiency

Cambodia’s vulnerability is often framed as a function of its development status, but the deeper issue is structural. It reflects an overreliance on imported energy and a limited capacity to diversify quickly. This is not unique to Cambodia. It is a global condition.

Over the past several decades, economies and corporations have optimized for efficiency. Supply chains have been streamlined, production has been concentrated in low-cost regions, and energy systems have been built around stable, predictable flows.

These choices have delivered growth and reduced costs, but they have also introduced a less visible form of risk. Efficiency, when taken to its logical extreme, eliminates redundancy. Without redundancy, systems become brittle.

Conflict is often the trigger, not the root cause. The underlying issue is concentration.

• A significant share of the world’s energy supply runs through a single geographic corridor, creating systemic vulnerability
• Countries with heavy dependence on imported fuel and limited alternatives remain exposed
• Tightly optimized supply chains leave minimal slack to absorb disruption

Similar patterns exist in semiconductor production and global food systems. Concentration increases efficiency, but it also increases dependency and reduces flexibility.

Diversification: from strategy to survival

Countries and businesses need to diversify to build resilience in times of uncertainty.

For countries, this means reducing dependence on a narrow set of energy sources and economic activities. It means investing in alternative energy, strengthening domestic capacity where feasible, and building systems that can adapt under stress.

For companies, the implications are equally profound. The traditional model of optimizing for cost, minimizing redundancy, and concentrating production has reached its limits. It performs well in stable conditions but fails under strain.

Diversification is no longer optional. It is central to resilience. It provides options, creates flexibility, and reduces the risk that a single point of failure disrupts the entire system.

Effective approaches include:

• Diversifying supply chains across regions, even at higher short-term cost
• Investing in multiple energy sources, particularly in energy-intensive sectors
• Designing for input substitution when materials become scarce or expensive
• Building operational slack so disruption in one area does not halt the entire system

These choices involve trade-offs. Diversification can be costly, and redundancy can appear inefficient. But the cost of fragility is often far greater.

Rethinking efficiency in an unstable world

For decades, efficiency has been the dominant principle of global economic design. But efficiency assumes stability. It assumes that supply chains function as expected, that energy flows uninterrupted, and that geopolitical tensions remain contained.

Those assumptions no longer hold.

Geopolitical tensions are rising. Climate-related disruptions are increasing. Technological dependencies are deepening. In such an environment, efficiency must be redefined.

The goal is not to abandon efficiency, but to balance it with resilience. Systems must be able to withstand shocks without collapsing. In a world defined by volatility, the most efficient system is the one that continues to function under stress.

In tightly coupled systems, disruption is enough. Failure does not require collapse.

From local disruption to global reckoning

The disruption of flows through the Strait of Hormuz is a real-time case study in systemic fragility. It shows what happens when flexibility is absent and when critical dependencies are exposed.

Cambodia’s experience is instructive not because it is exceptional, but because it is representative. It illustrates what happens when exposure meets disruption and highlights the consequences of overdependence.

Future disruptions are not hypothetical. They are inevitable. The question is not whether they will occur, but whether systems are designed to absorb them.

The lesson is not that globalization has failed, but that it has been built on assumptions of stability that no longer hold. The challenge now is not to retreat from integration, but to redesign it so that resilience becomes as central as efficiency.

The Strait of Hormuz is not just a regional issue. It is a warning about how the global system functions and how it can fail.

The time for incremental adjustment has passed. Governments and businesses must rethink how they build, invest, and operate in a world where disruption is no longer the exception, but the rule.
