The war is here. The Strait is closed. Who is paying the price—and how?

Since 28 February, when the United States and Israel launched strikes against Iran, the Strait of Hormuz has been effectively closed to commercial shipping. The IEA has called it the largest supply disruption in the history of the global oil market. Brent crude has surged past $120. The immediate military story dominates the headlines. But a second story—quieter, slower, and in many ways more consequential—is unfolding across three continents. Countries that have nothing to do with this war are being hurt by it.

Israel’s strategic planners have rightly focused on missiles, proxies, and nuclear timelines. But the global shockwave now reshaping the diplomatic environment in which Israel operates deserves equal attention. Allies that offered quiet support weeks ago are now dealing with energy emergencies, food price spikes, and domestic pressure to distance themselves. Understanding who is getting hurt, and how, is not peripheral to Israeli strategy. It is central to it.

To map this, I have constructed a Vulnerability Index covering 24 non-Gulf countries across seven dimensions: energy, food security, military commitments, trade and shipping, financial contagion, diaspora risk, and cyber threats. Each is scored 0–10 and weighted for the Hormuz-closure scenario that is now reality. The Gulf states are excluded—their exposure is self-evident. What follows is not.

Table 1 ranks the ten most vulnerable countries. The striking feature is not the scores themselves but the diversity of the dominant risk dimension. Japan’s crisis is energy. India’s is people. Egypt’s is bread.

Table 1: Top 10 Most Vulnerable Countries

Composite scores 0–10 (10 = most vulnerable). Red ≥ 7.0, orange ≥ 5.5, amber ≥ 4.0.

Lebanon (7.9) tops the list for the bleakest of reasons: a state already in collapse now tipped further into catastrophe by the Hezbollah front. Japan (7.0) comes second—a sophisticated economy whose entire energy architecture assumed the Strait of Hormuz would stay open. It no longer is. India (6.8) and Pakistan (6.7) are exposed through a channel most analysts have ignored entirely: the millions of their citizens working in the Gulf.

Before the closure, roughly one-fifth of the world’s oil—some 20 million barrels a day—transited Hormuz. For Japan, South Korea, and India, the shutdown is an energy emergency that is already being felt.

Japan’s 254-day strategic petroleum reserve buys time—but time is not a solution. As of early March, the Nikkei had already fallen roughly 8 per cent. South Korea, with about 70 per cent of its crude transiting the strait, triggered a circuit breaker on 4 March and has announced a 100 trillion won market stabilisation programme. India’s position is more precarious. With approximately 50 per cent of its crude arriving via Hormuz and total reserves—strategic plus commercial—of about 74 days, the country has drawn down its buffer faster than any other major importer. India also holds a stake in Iran’s Chabahar port, an investment that became a geopolitical liability overnight. For Israel, the implication is direct: Japan and South Korea are among the countries whose UN voting behaviour and diplomatic positioning Israel works hardest to influence. An energy crisis makes that task considerably harder.

Mitigation options exist but are thin. Saudi and Emirati pipelines can bypass Hormuz, but the IEA estimates their available spare capacity at only 3.5 to 5.5 million barrels per day—covering barely a quarter of the 20 million that normally transits. Iraq, Kuwait, and Qatar have no bypass infrastructure at all. Meanwhile, Chinese-flagged vessels appear to be among the few still transiting the strait, suggesting Beijing is carving out a protected corridor even as Western shipping retreats. Reserves buy months. Rerouting buys fractions. Neither buys a solution.

The Forgotten Dimension

The least-discussed vulnerability is carrying the greatest humanitarian weight. Tens of millions of South and Southeast Asian workers live in the Gulf. The war has put them at immediate physical risk and is severing remittance flows that entire economies depend on.

India’s 9.0 diaspora score is not an abstraction. According to India’s Ministry of External Affairs, approximately 9 million Indian nationals live in the six GCC countries. The 2023 Sudan evacuation—Operation Kaveri—involved some 4,000 nationals at risk and stretched Indian military and diplomatic capacity to its limit. A Gulf evacuation would be of an entirely different order of magnitude. The Philippines’ 2 million Overseas Filipino Workers in the Gulf generate remittances worth roughly 8 per cent of GDP. A sustained disruption is not an inconvenience. It is a recession.

The Australia Paradox

One country deserves special attention. Australia scores just 4.4 overall—a net exporter of energy and food, about as far from the Gulf as geography allows. Yet its military score is 7.0. AUKUS, Pine Gap, Five Eyes, and the broader alliance architecture mean Australia has already been drawn into the conflict’s diplomatic and operational dimensions. HMS Anson arrived at HMAS Stirling just weeks before the strikes. Australia’s vulnerability is not economic. It is strategic. And for Israel, it is a reminder that even the most supportive allies have domestic constraints that a wider war activates.

The cyber dimension of this index carries 10 per cent of the weighting, but the damage it captures is disproportionate. The UK (8.0), China (7.5), South Korea (7.0), and France (7.0) all score at the high end—not because their defences are weak, but because their critical infrastructure is high-value and already under active targeting. Port management systems, financial clearing networks, energy grid SCADA controllers, and undersea cable landing stations are all attack surfaces that a state-level adversary can reach without firing a missile. Iran’s cyber capabilities—demonstrated repeatedly against Israeli, Saudi, and Albanian targets in recent years—are now being deployed in the context of a shooting war, where the threshold for escalation has collapsed. For countries like the UK, whose financial centre clears trillions daily, or South Korea, whose semiconductor fabs supply the world, a successful cyber strike during a kinetic conflict would compound the energy shock with a technology shock. This is the dimension that turns a regional war into a systemic one.

What This Means for Israel

Vulnerability is dimensional, not scalar. Japan and Jordan score similarly overall but face entirely different crises—energy versus food. Policy responses that address one do nothing for the other. The international community cannot mount a single coherent response because there is no single coherent problem.

The most exposed countries are not the most discussed. India, Japan, and South Korea—three of the world’s five largest economies—sit in the top six. Their vulnerability is structural and will take years to unwind. The Western debate about this war barely mentions them.

Global disruption is already reshaping Israel’s diplomatic space. Countries dealing with energy emergencies, food crises, and mass evacuations do not have bandwidth for Middle Eastern diplomacy. Abraham Accords momentum, IMEC corridor planning, and quiet Asian normalisation have already stalled. The blast radius extends far beyond the blast—and it is widening by the week.

Note: The tables above present the ten most vulnerable of 24 countries assessed. The full index also covers Germany, France, Italy, Greece, Sri Lanka, Thailand, Singapore, Ethiopia, Kenya, South Africa, Brazil, Argentina, and New Zealand. The complete dataset and interactive dashboard are available from the author.

Methodology: Composite scores are weighted means across seven dimensions (Energy 20%, Food 18%, Military 16%, Trade 14%, Financial 12%, Diaspora 10%, Cyber 10%), calibrated against IEA, EIA, FAO, SIPRI, UNCTAD, World Bank, and IMF data. GCC states excluded. All Hormuz transit figures cross-referenced against EIA/Vortexa tanker-tracking data and Zero Carbon Analytics.
