The effective closure of the Strait of Hormuz amid escalating tensions in the Middle East has caused significant disruptions to global supply chains, particularly impacting Japan and India. Japan, which imports approximately 20% of its aluminum from the Middle East, faces heightened uncertainty in its aluminum supply. Japanese manufacturers are actively seeking alternative sources in Southeast Asia and Australia, while inventories have so far cushioned the immediate impact. However, aluminum prices have surged on the London Metal Exchange, with traders reporting increased volatility and concerns about further price spikes if the disruption persists. Technical analysis shows resistance levels forming around recent highs, and analysts warn that continued closure could trigger further upside in prices [1].
Japan's strategic petroleum reserve is undergoing its biggest stress test in years, as the government began releasing oil from the Kikuma national petroleum-stockpiling base on March 26 to mitigate supply risks. The revival of gasoline price subsidies is expected to drive demand higher, putting additional stress on reserves. Market analysts caution that prolonged instability could push global oil prices higher, with Japanese importers facing elevated costs and potential shortages. Policymakers are closely monitoring inventory levels and are prepared to adjust measures as needed [2].
The conflict has also prompted Southeast Asian countries, including Vietnam and the Philippines, to request oil aid from Japan. Japan's reserves are sufficient to cover over eight months of consumption, but officials emphasize that domestic energy needs take priority. The ongoing war in Iran has led to tighter oil supplies and rising prices, with both the Philippines and Vietnam exploring ways to reduce consumption and diversify energy sources. Market analysts highlight the importance of regional energy cooperation and note that oil prices remain elevated, with volatility expected to persist [3].
In India, major automakers Tata Motors and BMW plan to raise prices in April due to increased costs for metals and logistics stemming from the conflict and the closure of the Strait of Hormuz. Steel and aluminum prices have surged, and logistics providers face higher freight rates and insurance premiums. Industry sources estimate price hikes in the range of 2% to 5% across models, though exact figures have not been disclosed. Technical analysis indicates sharp gains in metal futures, and dealers warn that price increases could dampen demand in the short term, though sales remain robust for now [4].
To address the risk of energy shortages, the Japanese government will temporarily lift restrictions on coal-fired power plants. Japan relies on thermal power plants for 70% of its electricity, and the disruption in Middle Eastern oil and gas supplies has led Asian countries to push up spot market prices as they seek to reduce reliance on imports from the region [5].
CONCLUSION
The closure of the Strait of Hormuz has triggered a surge in commodity prices and forced governments and industries to take urgent measures to secure energy and raw materials. Japan is tapping strategic reserves and relaxing coal plant restrictions, while automakers in India are raising prices amid rising input costs. Market volatility is expected to persist as supply disruptions and geopolitical risks continue to shape global commodity and energy markets.
