The war involving the United States, Israel, and Iran entered its second week on March 6, 2026, with attacks and counter-strikes spreading across the Gulf and disrupting global energy flows. Oil prices surged sharply, Brent crude climbing 15% to around $84 per barrel, while markets braced for potential closure of the Strait of Hormuz. Asia, the world’s largest energy-importing region, faces the heaviest impact. Countries like China, India, Japan, South Korea, Taiwan, and Southeast Asian nations depend heavily on shipments through this narrow waterway, which carries about one-third of global seaborne crude and a fifth of liquefied natural gas. The conflict has already halted production at major facilities in Qatar and Saudi Arabia, raised shipping costs, and triggered bidding wars for scarce cargoes. Richer nations can outbid others, leaving more vulnerable economies short. This sudden squeeze raises a pressing question: how severe will the supply shock become, and which Asian countries are most at risk? The answers depend on the conflict’s duration, the Strait’s status, and how quickly alternatives can be found.
How Has the Conflict Disrupted Energy Flows to Asia?
The Strait of Hormuz is the main chokepoint. Roughly 13 million barrels of oil per day passed through it in 2025, along with a large share of global LNG. More than 80% of that LNG went to Asia in 2024. The war has already affected key suppliers. Qatar halted output at its Ras Laffan plant after Iranian strikes, and Saudi Aramco paused operations at Ras Tanura following a drone attack. These disruptions tightened supply and drove up prices fast.
Shipping has become more expensive and risky. Insurance premiums for tankers have risen sharply, and some routes face delays or rerouting. Even without a full closure, logistical friction—higher costs, slower transits, and crew safety concerns—has reduced flows. Richer importers can pay more to secure cargoes, while others wait longer or pay higher spot prices. This dynamic repeats patterns seen during the 2022 Russia-Ukraine crisis, when Europe outbid Asia for LNG.
Oil prices reflect the uncertainty. Brent jumped to $84, the highest since mid-2024, with early spikes reaching 12–15%. Natural gas prices rose as LNG trade faced risks. The U.S. granted India a 30-day waiver to continue buying discounted Russian crude, a temporary relief measure to stabilize markets. Yet the core issue remains: Asia’s heavy reliance on Gulf supplies leaves it exposed when those flows falter.
Which Asian Countries Face the Greatest Risks?
China and India stand out due to their scale. China, the world’s largest crude importer, buys about 1.4 million barrels per day from Iran—around 13% of its seaborne imports. Most Iranian cargoes were already at sea when the conflict began, covering four to five months of demand. China also holds large strategic reserves and can shift to Russian supplies. Analysts say China is unlikely to face shortages soon, but higher prices will raise costs across its economy.
India, the third-largest importer, has reserves for less than a month. It relies heavily on Middle East crude and has limited alternatives in the short term. Higher prices could drive up inflation, weaken the rupee, and slow growth. The next two weeks are critical; prolonged disruption could worsen fuel costs and affect food prices.
Japan, South Korea, and Taiwan are highly exposed. Japan imports 95% of its crude from the Middle East and is a top LNG buyer. South Korea gets 70% of its oil and 20% of LNG from the region. Taiwan sources about one-third of its LNG from Qatar. All three have reserves, but energy-intensive industries—semiconductors in Taiwan, manufacturing in South Korea and Japan—remain vulnerable. Governments are in preparation mode, urging conservation and exploring options.
Southeast Asia faces acute risks. Thailand, the Philippines, and others lack large reserves and depend on spot-market LNG and crude. Poorer nations risk being outbid by wealthier ones. Thailand suspended petroleum exports to protect domestic stocks, while Manila banned non-essential travel to cut fuel use. The region’s fast-growing economies are particularly sensitive to energy price shocks.
What Steps Are Governments and Markets Taking to Respond?
Countries are moving quickly to limit damage. The U.S. offered risk insurance to shippers and may deploy naval protection. India received a temporary waiver for Russian crude purchases. China can lean on reserves and alternative suppliers. Japan, South Korea, and Taiwan are drawing on stockpiles and urging energy savings.
Markets show a risk-off mood but no full panic. Stocks fell modestly, with energy and defense shares gaining while travel and consumer stocks dropped. Gold rose as a safe haven, and the dollar strengthened. Analysts note that the U.S. energy independence and OPEC+ spare capacity could soften long-term impacts. If the conflict eases quickly, effects may remain temporary.
Yet risks are real. Higher oil could fuel inflation and slow growth. Poorer nations may face fuel shortages, while richer ones pay more to secure supplies. The Strait’s status remains the key variable: any prolonged closure would push prices much higher and disrupt trade broadly.
What Could This Mean for Asia’s Economic Outlook?
The conflict tests Asia’s energy security. China and India’s scale magnifies impacts, but their reserves and alternatives offer buffers. Japan, South Korea, and Taiwan face higher costs in key industries. Southeast Asia risks shortages and inflation, especially in import-reliant economies.
Longer-term, the crisis could accelerate diversification. Renewables, LNG from other sources, and strategic reserves become more attractive. Governments may rethink energy policies to reduce Gulf dependence. The event also highlights Asia’s exposure to distant conflicts, reinforcing the need for regional cooperation on supply security.
The economic fallout from the Iran conflict connects immediate supply shocks to Asia’s broader vulnerabilities. Oil’s spike and market unease show real risks, especially for import-heavy economies. Responses—waivers, reserves, conservation—provide short-term relief, but sustained disruption could strain growth and inflation. The next weeks will reveal whether the Strait stabilizes or tightens further. For Asia, the crisis is a reminder that energy security shapes economic stability. Diversification and preparedness will matter more than ever in the months ahead. The region’s ability to adapt will help determine how deeply this shock affects its future.
