The ongoing war in Iran and the closure of the Strait of Hormuz have triggered a severe energy shock across Asia, with Thailand, Japan, Southeast Asia, and the Philippines experiencing sharp increases in oil and energy prices, and widespread disruptions to supply chains and economic activity [1][2][3][4][5][6]. Thailand, which relies on the Middle East for 60% of its oil, faces one of its most severe crises in history, as sectors from tourism to farming, street food sales, and fishing are hit by soaring fuel costs. Oil futures and energy prices have spiked, with technical analysis showing resistance at recent highs and analysts warning of further volatility if the conflict persists [1]. Market strategists advise caution and hedging energy exposure, as traders expect potential breakouts in oil prices should geopolitical tensions worsen [1].
Japan's independent power retailers have halted new corporate contracts due to a more than doubling of wholesale electricity prices since February, driven by the Iran war. Saudi Arabian crude import prices for Japan have jumped 80% in a month, and power futures trading has reached record highs. Many retailers are reassessing risk exposure and shifting away from fixed-rate plans, with analysts warning that continued price volatility could force exits from the market or higher costs for businesses [2]. The broader impact is being closely watched by policymakers and market participants, with concerns about spillover effects into other sectors of the Japanese economy [2].
Across Southeast Asia, consumers face higher prices for food and fuel, with companies like Grab in Singapore raising fuel surcharges and Vietnam's Habeco increasing beer prices due to higher logistics costs. In Thailand, the fishing sector is reluctant to operate due to surging fuel expenses. Analysts caution that persistently high oil prices may reduce consumer spending and slow economic growth, with governments considering subsidies to cushion the blow. Technical indicators suggest resistance in regional equity markets if oil prices remain elevated, and sector rotation toward energy stocks is expected [3]. Market sentiment is fragile, with traders closely monitoring developments in the Middle East [3].
The Philippines has responded by rolling out new transport subsidies, allocating $13 million to support commuters and public transport operators facing increased fuel expenses. Operators will receive up to 100 pesos ($1.7) per kilometer to help maintain affordable fares and sustain operations [4].
Major shipping companies, including Mitsui O.S.K. Lines, have been severely affected by the closure of the Strait of Hormuz, prompting a review of earnings forecasts and structural changes in fleet deployment. The CEO of Mitsui O.S.K. Lines warned of a fundamental shift in supply chain design and long-lasting inflationary pressures, with shipping rates and insurance premiums surging. The company is considering investments in alternative shipping lanes and logistics hubs outside the Middle East, and market analysts predict elevated freight rates on Asia-Europe and Asia-US routes if the crisis continues [5].
Asian energy importers, including South Korea, Japan, and Bangladesh, are seeking to diversify supply by increasing imports from Kazakhstan. However, Kazakhstan faces significant bottlenecks due to limited pipeline capacity, geographical constraints, and underdeveloped export infrastructure. Most Kazakh oil transits through Russia, exposing shipments to geopolitical risks. While Asian buyers are exploring long-term contracts and joint investments, progress has been slow, and logistical challenges persist [6].
CONCLUSION
The Iran war and closure of the Strait of Hormuz have caused a high-impact energy shock across Asia, leading to surging prices, disrupted supply chains, and urgent government interventions. Market sentiment is negative, with analysts and industry leaders warning of prolonged volatility and inflationary pressures. The situation remains fluid, and further escalation could exacerbate the crisis, prompting continued caution and strategic adjustments by businesses and policymakers.
