By the time Asian markets opened on Monday, March 2, 2026, the arithmetic of energy exposure was already impossible to ignore. Brent crude had briefly surged to $82.37 a barrel — its highest since January 2025 — before settling around $79.20, an 8.5% single-session spike. West Texas Intermediate climbed nearly 7%, touching $75.33 at its intraday high. Fox News For Europe and the United States, the jump in oil prices was a headache. For Asia, it was an existential alarm bell.
The trigger was seismic: on February 28, 2026, the United States and Israel launched a coordinated military operation against Iran — codenamed “Operation Epic Fury” by the Pentagon and “Operation Roaring Lion” by the Israel Defense Forces — targeting key officials, military commanders, and strategic facilities, with the stated aim of regime change. Wikipedia Among the dead: Supreme Leader Ali Khamenei, who had ruled the Islamic Republic for more than three decades. The fallout has been swift, ferocious, and for the energy-hungry economies of Asia, deeply consequential.
Understanding Asia’s vulnerability requires grasping how rapidly this crisis metastasized. On the morning of March 1, Iran retaliated by launching missiles and drones on Israel, the UAE, Qatar, Kuwait, Bahrain, Jordan, and Saudi Arabia. By March 2, the war had spread beyond Iran itself, with Israel and Hezbollah exchanging fresh attacks. Wikipedia
A refining facility was damaged at Aramco’s Ras Tanura in Saudi Arabia, causing a contained fire. Explosions were reported in Dubai, Abu Dhabi and Doha. An oil refinery in Kuwait was struck by shrapnel. Wikipedia The conflict had leapt from geopolitics to energy infrastructure within hours.
The Strait of Hormuz — that narrow 33-kilometre passage between Oman and Iran — moved from theoretical flashpoint to operational crisis. The Strait is not formally closed, but Kpler vessel tracking shows that commercial operators, major oil companies, and insurers have effectively withdrawn from the corridor. Insurance premiums had already reached six-year highs ahead of the strikes. The result: a de facto closure for most of the global shipping community. Kpler
More than 14 million barrels per day passed through the Strait on average in 2025, or about a third of the world’s total seaborne crude exports. Tanker traffic has effectively come to a halt as shipping companies take precautionary measures. CNBC As Matt Smith, oil analyst at Kpler, put it: “Tankers are starting to build by the Strait of Hormuz, but nothing seems to be going through at the moment — tankers are definitely spooked.”
Here is where the story shifts from Middle Eastern geopolitics to Asian economic fragility. The numbers, when laid out plainly, are startling.
In 2024, oil flow through the Strait of Hormuz averaged 20 million barrels per day, equivalent to about 20% of global petroleum liquids consumption. Flows through the strait made up more than one-quarter of total global seaborne oil trade. U.S. Energy Information Administration And the overwhelming majority of that oil heads east.
The EIA estimated that 84% of crude oil and condensate shipments transiting the strait headed to Asian markets in 2024. A similar pattern appears in the gas trade, with 83% of LNG volumes moving through the Strait of Hormuz destined for Asian destinations. China, India, Japan and South Korea accounted for a combined 69% of all Hormuz crude oil and condensate flows. Al Jazeera

Analysts at Morgan Stanley have been clear-eyed about the asymmetry of this crisis. While headlines focus on China — the world’s largest crude importer — the bank’s analysts emphasise that India, South Korea and others could fare worse. South China Morning Post The distinction matters enormously for investors and policymakers attempting to price risk.
Morgan Stanley’s Global Commodities Strategist Martijn Rats has outlined four scenarios for the Iran conflict’s oil market impact. The most severe, considers a potential shipping shock where the real risk isn’t wells shutting down — it’s shipping disruption. If transit times were extended even modestly, effective shipping capacity could fall sharply, creating what amounts to a temporary tightening of about 2 to 3 million barrels per day — or about 6% of global seaborne supply. That is a logistics shock, not a production outage, but it would push prices toward early-2022-type levels, at least briefly. Morgan Stanley
Early-2022 type levels, to be clear, meant oil above $100 per barrel. Bob McNally, former White House energy adviser, told CNBC that if there is no sign of de-escalation, prices could spike above $100 per barrel. CNBC Analysts at Citi warned Brent could trade between $80 and $90 in the coming days.
Imagine Tokyo’s lights dimming because of a waterway 7,000 kilometres away. It is not a hypothetical. Japan sources around 95% of its oil imports from the Middle East, of which some 70% passes through the Strait of Hormuz. Japan imported 2.8 million barrels of oil per day in January, of which 1.6 million barrels per day came from Saudi Arabia, with additional supply from the UAE, Kuwait and Qatar. MarketScreener
Japan’s LNG position offers some diversification — Japan, the world’s second-largest LNG importer, sources 40% of its supply from Australia MarketScreener — but this does not insulate it from oil price shocks. A sustained oil price of $120 to $130 would increase Japan’s import bill and widen its trade deficit, putting fresh downward pressure on the yen and complicating the Bank of Japan’s efforts to combat inflation, potentially pushing the Japanese economy into stagflation, resulting in a 0.6% lower GDP than expected for 2026. Energy Tracker
Japan holds emergency oil reserves equivalent to 254 days of consumption — a meaningful buffer. But Japan’s energy freight companies are readying for a potential blockade of the strait, with shipping giant Mitsui OSK saying: “We’re currently taking measures to shorten as much as possible the time spent by our vessels in the Gulf.” France 24
Seoul sits in a difficult position. South Korea relies almost totally on imports for its energy, buying around 70% of its oil and 20% of its LNG from the Middle East. The country is particularly dependent on its main supplier Saudi Arabia, which accounted for a third of its oil imports last year. France 24
Seoul’s trade and energy ministry confirmed there have been no disruptions so far, but acknowledged preparations underway. The government and industry stakeholders have prepared for emergencies by maintaining a strategic petroleum reserve equivalent to about 200 days of supply. France 24 That cushion is considerable, but the real threat is not a sudden shutoff — it is a sustained price elevation that inflates manufacturing costs, widens Korea’s trade deficit, and pressures the won.
India’s situation is arguably the most precarious in the near term, despite the government’s reassurances. India’s dependence on the Strait of Hormuz has surged to around 50% of its total crude imports and has been rising in recent months. So far in 2026, India imported nearly 2.6 million barrels per day from Gulf countries. ThePrint
The country had diversified into Russian oil following the Ukraine war, but that avenue has narrowed. Imports from Russia have declined in early 2026 due to tightened US sanctions, while purchases from Gulf nations — particularly Saudi Arabia and Iraq — have surged to multi-year highs. ThePrint
India’s strategic reserves cover only approximately 9 to 25 days of import requirements — a fraction of Japan’s or South Korea’s buffers. India has activated contingency plans to safeguard energy supplies, but apart from amassing strategic national stockpiles to weather immediate disruptions, there may be limited alternatives for countries dependent on getting their energy supplies through the strait. The Conversation
India’s Petroleum Minister Hardeep Singh Puri sought to reassure markets, writing on X that “we have diversified our supplies in the past few years and a large volume of our supplies do not come through the Strait of Hormuz.” The data suggest the picture is more complicated than that.
China’s exposure is vast in absolute terms — it is the world’s largest crude importer — but Beijing has spent years building strategic buffers. Roughly half of China’s oil imports come from the Middle East. The country purchased an average of 1.38 million barrels per day of Iranian oil last year, or about 13% of all its seaborne imports. Another 42 million barrels of Iranian crude was stored on tankers in Asia in late January. MarketScreener
China has also spent years growing its strategic reserves, building new storage sites and buying crude from a global market in surplus. Beijing closely guards the size of reserves, but analysts estimate them at around 900 million barrels, or just under three months of imports. MarketScreener Additionally, Kpler data shows that limited traffic through the Strait continues — primarily Iranian and Chinese-flagged ships — giving Beijing a marginal operational advantage.
It is worth pausing to appreciate the geographic severity of this situation. Ships crossing the Strait of Hormuz carry around one-fifth of global oil supplies — about 20 million barrels per day. This makes the strait the most critical energy chokepoint in the world. The Conversation
Iran has for years threatened to weaponise the strait, and the government has reportedly said that closing it would be “easier than drinking a glass of water.” Now, with Khamenei dead and a successor regime uncertain, the threat calculus has shifted in unpredictable ways. Iran has already attacked US military bases, Israel and targets across the region. The conflict has damaged air hubs, rocked densely populated areas and disrupted oil shipments. CNN
Ali Vaez, director of the Iran Project at the International Crisis Group, has warned that “closure of the Strait of Hormuz would disrupt roughly a fifth of globally traded oil overnight — and prices wouldn’t just spike, they would gap violently upward on fear alone.” The shock, he added, would “reverberate far beyond energy markets, tightening financial conditions, fuelling inflation, and pushing fragile economies closer to recession in a matter of weeks.”
Asian economies face the greatest structural vulnerability due to their dependence on Gulf energy imports. Higher oil benchmarks would translate into elevated input costs across manufacturing, transportation and agriculture — sectors that form the backbone of most Asian economies. Middle East Briefing
The macroeconomic channels are well understood: higher oil prices push up production costs, feed into consumer price inflation, widen current account deficits in oil-importing nations, and create pressure on central banks caught between taming inflation and supporting growth. For India and South Korea — both running current account positions sensitive to energy costs — the arithmetic is particularly painful.
As of March 1, 2026, approximately 170 containerships with a combined capacity of around 450,000 TEU — roughly 1.4% of the entire global container fleet — are currently inside the strait and unable to exit. Middle East Briefing The freight market dislocation adds yet another inflationary layer.
OPEC+ has responded, but modestly: the group approved a modest production increase of 206,000 barrels per day — a figure that surprised analysts expecting a larger response given the conflict. The decision reflects deliberate risk management rather than market indifference, as spare capacity is concentrated in Saudi Arabia and the UAE — the same countries now absorbing Iranian missile strikes. Kpler
Asian governments are not without options — but none are painless or immediate.
Strategic reserves represent the first line of defence. Japan’s 254-day buffer and South Korea’s 200-day reserve are genuine shock absorbers. India’s thinner cushion — covering two to three weeks of refinery requirements in practice — is the weakest link.
Supply diversification is a longer game. Before 2022, Russia was a marginal supplier to most of Asia. After the Ukraine war, it became a major source for India. That avenue, now constrained by sanctions, illustrates how geopolitical developments can rapidly redraw energy supply maps. Africa — particularly Angola and Nigeria — and Central Asia offer partial alternatives, but logistical infrastructure for scaling those routes quickly does not yet exist.
Pipeline bypasses offer limited relief: Saudi Arabia and the UAE have infrastructure to bypass the strait, potentially mitigating disruptions, but their transit capacity remains very limited — around 2.6 million barrels per day. France 24 Against 20 million barrels per day in normal flow, that is barely a rounding error.
There is a larger lesson embedded in this crisis, one that Asia’s policymakers have been slow to fully absorb. The Strait of Hormuz risk triangle — geographic chokepoint, geopolitical conflict, and near-total fossil dependence — puts Japan at risk during any Gulf crisis. Decisive investment in wind, solar and electrification could slash fossil fuel imports before 2030, transforming today’s liability into a competitive, low-carbon edge. Energy Tracker
The same logic applies to India, South Korea, and the broader region. Energy security and climate ambition, often positioned as competing priorities, are in fact two sides of the same coin. Every gigawatt of renewable capacity installed is one less barrel that needs to transit a contested strait.
For now, though, the immediate calculus is grim. How the oil market ultimately reacts will depend on whether the war leads to a prolonged disruption to traffic through the Strait of Hormuz. CNBC As UBS analysts told clients in a Sunday note: “We view the pace of the rebound in traffic through Hormuz and the extent of Iranian retaliation as key for the oil price in the next few days.”
Morgan Stanley, for its part, retains a broadly constructive view on US equities — but acknowledges the conditions under which that view could break. Morgan Stanley strategists see the eruption of conflict in Iran and the Middle East as unlikely to derail their bullish view on US stocks, barring a sharp and sustained surge in oil prices. Bloomberg Asia, without America’s domestic energy buffers, does not have that luxury.
The Strait of Hormuz has always been Asia’s Achilles heel. The events of February 28, 2026 have not created a new vulnerability — they have ripped away the comfortable fiction that it could be managed indefinitely from a distance.
