Asia Forced to Maximize Coal Output After Hormuz Closure - March 2026

China, the world's largest coal consumer and producer, is at the center of an unprecedented surge in coal reliance across Asia following the closure of the Strait of Hormuz. The blockade, triggered by the US-Israel military offensive against Iran on February 28, 2026, has severed a maritime route through which over 80% of Middle Eastern crude oil and LNG shipments flow toward Asian markets. As oil and gas supplies collapse, Asian economies from Beijing to New Delhi to Seoul are turning to coal as their primary emergency energy buffer.

China accounts for more than half of global coal consumption and produces approximately 4.8 billion tonnes per year. In 2024, coal generated 59% of the country's electricity and represented over 55% of total primary energy supply, making it by far the most coal-dependent major economy on earth. The Strait of Hormuz crisis has reinforced coal's strategic role: Beijing raised coal production to record levels in early March 2026 while simultaneously expanding renewable and nuclear output to cushion the blow of disrupted oil and gas imports.

Around 40% of China's seaborne oil imports normally transit through the Strait of Hormuz, and roughly 30% of its LNG comes from Qatar and the UAE. However, China entered the crisis in a stronger position than its neighbors. Strategic petroleum reserves stand at an estimated 1.2 to 1.4 billion barrels, sufficient for three to six months of coverage depending on estimates. In January and February 2026, Chinese crude procurement surged 16% year-on-year to 96.93 million tonnes, suggesting Beijing had anticipated the escalation. The country also secured continued access to Iranian and Russian oil through unofficial shipping fleets and negotiated limited passage for Chinese-linked tankers through the strait.

China's energy mix provides an inherent shock absorber that other Asian economies lack. Because its electricity grid runs predominantly on domestically mined coal, nuclear power, and rapidly expanding renewables, it is structurally less exposed to oil price spikes than neighbors who depend on imported LNG for power generation. The rapid adoption of electric vehicles, which now represent nearly half of new car sales in the country, has further reduced gasoline demand growth. Analysts at OCBC noted that China may be less sensitive to a prolonged Hormuz closure than many of its Asian peers, thanks to declining structural dependence on oil.

Despite these buffers, vulnerabilities remain. The disruption of Qatari LNG flows threatens China's industrial gas consumers and petrochemical feedstock supply chains. The global LNG price surge of over 65% since the crisis began is already driving up costs. China responded by restricting refined fuel exports, including diesel and gasoline, to preserve domestic supply. This decision, while stabilizing China's internal market, amplified fuel shortages across Southeast Asia and worsened conditions for regional trading partners.

India, the world's second-largest coal consumer, faces a far more acute crisis. Coal accounts for approximately 70% of India's electricity generation, the highest ratio among major Asian economies, and around 60% of total primary energy supply. Roughly 45-50% of India's crude oil imports and 60% of its LPG requirements transit through the Strait of Hormuz. After QatarEnergy suspended production at Ras Laffan following Iranian retaliatory strikes, 40-45% of India's LNG imports were cut off. Petronet LNG, the country's largest gas importer, declared force majeure, triggering a cascade of supply disruptions to major distributors including GAIL, Indian Oil Corporation, and Bharat Petroleum.

India's power ministry issued emergency directives to bring coal-fired plants back online from planned maintenance and postpone all scheduled shutdowns ahead of the summer peak. A government tender for 12,000 megawatt-hours of gas-fired power for the April-June period received zero bids, confirming a total collapse of gas-based electricity economics. The Coal Ministry confirmed on March 13 that national coal stocks stood at approximately 210 million tonnes, sufficient for 88 days, with Coal India Limited's pithead stocks reaching 121.39 million tonnes.

On March 9, the Indian government invoked the Essential Commodities Act, issuing the Natural Gas (Supply Regulation) Order, 2026, which created a four-tier rationing system. Household piped gas, CNG for transport, and LPG production received full supply guarantees. Fertilizer plants were capped at 70% of their six-month average consumption. Industrial users were limited to 80%. Oil refineries were ordered to cut gas consumption to 65% of recent levels. On March 11, the government authorized the temporary use of biomass, kerosene, and coal by the hospitality sector, reversing years of clean cooking campaigns.

The economic impact on India has been severe. In Mumbai, an estimated 20% of hotels and restaurants closed due to LPG shortages. In Gujarat's Morbi district, 170 ceramic tile factories shut down, displacing approximately 100,000 workers. Across Chhattisgarh, households reverted to burning coal and firewood for cooking. Analysts estimate that every $10 per barrel increase in crude oil adds $13-14 billion to India's annual import bill. Goldman Sachs projected the country's current account deficit to widen to $37 billion in 2026, and the rupee fell to a record low of 92.48 against the dollar.

South Korea, where coal generates approximately 29% of electricity and gas another 26%, announced emergency measures on March 16, 2026. The government lifted caps on coal-fired power output, previously restricted to 80% of installed capacity, and ordered nuclear reactor utilization to increase from the high-60% range to 80%. Seoul imports roughly 70% of its oil and 20% of its LNG from the Middle East, and about 15.5% of total LNG imports come from Persian Gulf countries exposed to a Hormuz closure. Coal-fired generation had already risen to an average of 20.7 GW on March 3, a 4.8 GW jump compared to the previous year, reflecting the sharp economic advantage of coal over surging LNG prices. The government accelerated maintenance at six nuclear reactors and is considering reactivating mothballed coal plants. A gasoline price cap was introduced at 1,724 won per litre. Wood Mackenzie projected that if the disruption lasts two months, Northeast Asian LNG demand could fall by 4-5 million tonnes through the third quarter of 2026, as coal switching displaces gas across the region.

Japan, where coal provides roughly 30% of electricity generation alongside gas at approximately 31%, holds more robust reserves than most of its neighbors. Japanese onshore crude inventory stands at 350 million barrels, providing roughly 150 days of supply at current refinery run rates. Japanese refiners, who source about 95% of their crude from the Gulf, have requested government authorization to draw from strategic stockpiles. Japan's coal imports from Australia and Indonesia remain unaffected by the Hormuz closure, giving Tokyo continued access to thermal coal for power generation. However, 75-80% of Japan's oil imports depend on the strait, and the country has virtually no domestic fossil fuel production, making prolonged disruption a serious threat to industrial output and transportation.

Taiwan faces perhaps the most constrained position among developed Asian economies. Coal generates approximately 36-39% of the island's electricity, while gas-fired plants account for 42-47%, almost entirely fueled by imported LNG. Taiwan imports over 97% of its total energy needs and holds only 11 to 14 days of LNG reserves under normal consumption. With its last nuclear reactor decommissioned in May 2025, Taiwan has lost a significant baseload alternative. The island must now either purchase expensive spot LNG on the open market or restart mothballed coal units to avoid power shortages. Either option drives energy costs sharply higher in an economy where the semiconductor industry alone consumes roughly half of industrial electricity.

Across Asia, the International Energy Agency coordinated the release of 400 million barrels from emergency reserves to stabilize markets. However, this volume represents only about 20 days of normal Hormuz flows and approximately four days of total global consumption. Brent crude surged past $100 per barrel, peaking at $126. Global LNG spot prices jumped over 65%, with carrier freight rates soaring from $40,000 to $300,000 per day. Coal prices, by contrast, rose only 12% over the same period, reinforcing coal's role as the most price-stable fossil fuel during the crisis.

The ING Group highlighted the structural difference: India and China possess an inherent cost advantage because coal accounts for over half of their energy supply, allowing them to substitute oil and gas with coal at the margin. Thailand, South Korea, the Philippines, and Japan, by contrast, face higher vulnerability due to their greater dependence on imported oil and gas with limited substitution capacity.

The crisis has abruptly reversed clean energy trajectories across the continent. In 2025, coal-fired power generation had declined simultaneously in both China (by 1.6%) and India (by 3%) for the first time since 1973, driven by record renewable deployments. China added over 300 GW of solar and 100 GW of wind in 2025. India added 41 GW of renewables, pushing non-fossil capacity past 52% of total installed generation. South Korea saw fossil fuels drop below 50% of electricity for the first time in April 2025. That historic progress has now been overtaken by emergency coal mobilization across the region, as governments prioritize energy security over decarbonization timelines.

The situation remains volatile. The longer the Strait of Hormuz remains effectively closed, the deeper Asia's renewed dependence on coal will become, setting back emission reduction targets that had shown their first tangible results in half a century.
