Energy-Hungry Asia Learns Vital Lessons from Iran War

The four-month Iran War, which commenced with a U.S.-Israeli joint assault in February 2026, created a historic shock for energy markets, even as a lasting peace deal in the Persian Gulf remains elusive. Energy-dependent Asian nations acutely felt their vulnerabilities due to the closure of the Strait of Hormuz and disruptions to energy flows. While the crisis's repercussions are still far-reaching, policymakers across Asia are recalibrating their energy priorities and developing future strategies.

The conflict escalated following the initial U.S. and Israeli strikes on February 28, 2026, triggering Iranian retaliatory attacks that spread across the region. A key development was Iran's effective closure of the Strait of Hormuz, a critical maritime chokepoint through which approximately 20% of global oil supplies and significant liquefied natural gas (LNG) volumes pass. The war caused substantial damage to oil and gas facilities in the Gulf, forcing major energy companies like QatarEnergy, Bahrain Petroleum Company (BAPCO), Kuwait Petroleum Corporation (KPC), and Abu Dhabi National Oil Company (ADNOC) to declare force majeure. Consequently, international Brent crude oil prices surged, surpassing $92 per barrel in March and $103 in April, even climbing above $120 per barrel after the Strait of Hormuz closure. LNG spot prices in Asia saw an increase of over 140%.

Asia, with its high reliance on Middle Eastern energy imports, was disproportionately affected by the crisis. East Asian countries import about 60% of their oil, Japan 75%, and India procures over 55% of its crude oil and more than 50% of its LNG from Qatar and the United Arab Emirates. The crisis led to fuel shortages and rationing from India and Pakistan to Australia, accompanied by frantic searches for alternative short-term supplies. Countries such as the Philippines, Thailand, Vietnam, Indonesia, Malaysia, Bangladesh, and South Korea implemented emergency measures, including work-from-home directives and four-day work weeks. This resulted in billions of dollars in increased import bills for regional economies; for instance, ASEAN experienced a monthly increase of $3.36 billion.

The broader economic and political context of the Iran War demonstrated that energy security has become central to national strategies. The conflict exposed that despite their deep economic exposure to Middle Eastern energy markets, Asian states have wielded limited influence over de-escalation dynamics in the region. The crisis accelerated a structural shift in global energy investments, prompting diversification away from Middle Eastern supply routes. However, this also created a tension between immediate energy needs and long-term climate goals, as some Asian countries increased coal usage to ensure energy security.

Analysts and market expectations suggest that Asia will undergo fundamental changes in its energy strategies moving forward. Policymakers are focusing on building larger strategic reserves (like India's plans for crude, liquefied petroleum, and natural gas reserves), diversifying fossil fuel suppliers (Japan's refinery upgrades to process crude from various sources, and a shift towards Russian crude and U.S./Australian LNG), accelerating the transition to renewable energy, and exploring nuclear power. The International Energy Agency (IEA) anticipates a significant boost to renewables and nuclear power due to the crisis. However, with full normalization of Middle Eastern energy exports not expected until mid-to-late 2027, Asian nations face a significant challenge in balancing energy security with their climate commitments.
