The escalation of hostilities in the Middle East in early April 2026 effectively shut down commercial traffic through the Strait of Hormuz, a chokepoint that carries about 20 percent of the world’s crude oil and liquefied natural gas (LNG) shipments. The immediate consequence has been a sharp uptick in gasoline, diesel and jet‑fuel prices across the Asia‑Pacific, where roughly 60 percent of crude oil and almost a third of LNG imports historically passed through the narrow waterway.
The disruption has reverberated far beyond the energy sector. The Gulf states are also the world’s largest exporters of nitrogen‑based fertilizers, and the timing of the blockage coincides with the planting season for staple crops in South and Southeast Asia. Delays in fertilizer deliveries could translate into lower yields and higher food prices later in the year, a risk that the International Food Policy Research Institute has warned could spark a secondary crisis in food‑insecure regions.
For policymakers and market observers, the key question is which Asian economies can weather the shock and which are likely to feel the strain most acutely. The answer hinges on three variables: the share of energy imports that transit Hormuz, the depth of strategic petroleum reserves, and the degree of diversification in supply sources.
Japan, the world’s third‑largest oil consumer, imports about 30 percent of its crude through the strait, according to data from the Ministry of Economy, Trade and Industry. Its strategic reserves, while sizable, cover only 90 days of consumption, a level that the International Energy Agency deems insufficient for a prolonged supply interruption. Japan’s reliance on long‑term LNG contracts with Qatar and the United States mitigates some risk, but the country still faces a steep price curve for spot cargoes, which have risen by more than 40 percent since the strait’s closure.
South Korea mirrors Japan’s exposure. The Korea Energy Agency reports that roughly 28 percent of the peninsula’s oil imports historically arrived via Hormuz, and its strategic stockpile is calibrated for 80 days of demand. The nation’s heavy reliance on imported petrochemicals amplifies the impact, as higher feedstock costs threaten to erode the competitiveness of its export‑driven manufacturing sector.
India, the world’s second‑largest oil importer, has a slightly lower dependence on Hormuz, with about 20 percent of its crude oil arriving through the waterway, according to the Ministry of Petroleum and Natural Gas. However, India’s strategic reserves cover only 60 days of demand, well below the global average. The country’s rapid growth in LNG consumption—now accounting for 35 percent of its total gas use—means that the disruption to Hormuz‑borne LNG cargoes is already inflating power generation costs, a pressure that could spill over into the broader economy.
China presents a more nuanced picture. While the country’s overall oil import share from Hormuz is estimated at 15 percent by the National Development and Reform Commission, its massive strategic reserve—equivalent to 180 days of consumption—offers a buffer that could last several months. Nevertheless, China’s LNG imports are heavily weighted toward Gulf supplies, with the China National Petroleum Corporation indicating that about 40 percent of its LNG cargoes originate from the Persian Gulf. The sudden scarcity of spot LNG has already pushed contract prices upward by roughly 30 percent, a development that could affect downstream industries ranging from steelmaking to electronics.
Southeast Asian economies are generally less exposed to Hormuz‑origin oil but are more vulnerable to fertilizer shortages. Vietnam, the Philippines and Thailand import over 70 percent of their nitrogen‑based fertilizers from Gulf producers, according to the United Nations Commodity Trade Statistics Database. The timing of the blockage means that shipments slated for the March‑May planting window are delayed, raising concerns among agronomists that yield gaps could emerge if alternative supplies cannot be sourced in time.
Indonesia, the region’s largest LNG importer, has diversified its supply chain through contracts with Australia, Malaysia and the United States. The Indonesian Ministry of Energy and Mineral Resources notes that only 12 percent of its LNG imports historically passed through Hormuz, a figure that cushions the country from immediate price spikes. However, Indonesia’s reliance on imported diesel for its vast archipelagic transport network means that higher fuel costs could still strain public finances.
Singapore, a global oil‑trading hub, is less a consumer than a conduit. The city‑state’s strategic reserves are modest, but its position as a re‑export center allows it to tap alternative supply routes, such as the Cape of Good Hope or the Suez Canal, albeit at higher shipping costs. Analysts at the Monetary Authority of Singapore have warned that prolonged disruption could raise freight rates and erode the city’s competitive edge in energy logistics.
The broader geopolitical context adds another layer of complexity. The United States has signaled a willingness to increase naval patrols in the Gulf to secure alternative shipping lanes, while Russia has offered to route additional crude through the Black Sea, a move that could shift trade patterns in the longer term. Meanwhile, the European Union is negotiating emergency fertilizer supplies from North Africa to offset the shortfall from Gulf exporters.
For Asian policymakers, the immediate priority is to secure alternative supply channels and to manage domestic price pressures. Countries with robust strategic reserves are likely to avoid abrupt rationing, but all will need to contend with higher input costs that could feed through to consumer prices. In economies where food security is already fragile, delayed fertilizer deliveries could exacerbate existing vulnerabilities, potentially igniting social unrest if staple food costs climb sharply.
In sum, the Hormuz energy shock has laid bare the varying degrees of exposure across the Asia‑Pacific. Nations such as Japan, South Korea and India, whose energy imports are heavily weighted toward the strait and whose reserves are relatively thin, face the steepest adjustment curve. China’s deep reserves provide a temporary shield, while Southeast Asian states are more likely to feel the repercussions in the agricultural sector rather than the energy market. The unfolding situation underscores the strategic importance of diversified supply chains and the need for coordinated regional responses to mitigate the cascading effects of geopolitical disruptions on global markets.
