The surge in oil prices, driven by the ongoing conflict in Iran and the effective closure of the Strait of Hormuz — through which approximately 20% of global crude oil supply passes — is creating uneven economic impacts worldwide. Net oil-importing countries, particularly those heavily reliant on Middle Eastern supplies and with limited financial buffers, face the greatest challenges. This energy shock increases costs for transportation, manufacturing, and food, straining growth and public finances. Below, we examine the three countries likely to be hit hardest.
1. India
India ranks among the world's largest oil importers, sourcing roughly 60-85% of its crude from the Middle East. The blockade of the Strait of Hormuz has severely disrupted its supplies, forcing the government to prioritize liquefied petroleum gas (LPG) for households over industry and to seek alternative shipping routes. A sustained rise in oil prices worsens its current account balance, accelerates inflation affecting hundreds of millions, and slows industrial growth. Economists note that every 10% increase in oil prices can significantly deteriorate India's trade position. With an expanding economy but moderate fiscal buffers, India risks reduced investment and greater pressure on energy subsidies.
2. Japan
As the world's third-largest economy with nearly 100% energy import dependence, Japan is highly sensitive to oil shocks. Around 90-95% of its petroleum comes from the Gulf region, making it one of the most exposed nations to disruptions in the Strait of Hormuz. Higher prices drive up electricity, transportation, and manufacturing costs — critical sectors for its export-oriented model. Past similar spikes have reduced GDP growth and fueled inflation, prompting government interventions such as subsidies or the release of strategic reserves. With high public debt and an aging population, Japan has limited room to absorb these costs without harming consumption and industrial competitiveness.
3. Philippines
In Southeast Asia, the Philippines stands out for its vulnerability: it imports nearly 90-96% of its oil from the Middle East and maintains an economy reliant on transportation and light manufacturing. Gasoline prices have already risen sharply, directly affecting households and businesses. Countries like the Philippines, with smaller strategic reserves and limited subsidy capacity, see the shock quickly translate into higher inflation for food and services. Analysts highlight that such economies experience current account deteriorations equivalent to several percentage points of GDP from moderate oil price increases. The impact is amplified by dependence on tourism and remittances, sectors sensitive to elevated energy costs.
Other nations such as South Korea, Thailand, or Vietnam also face severe pressures, but India, Japan, and the Philippines combine large economic scale with deep structural dependence. In the short term, this scenario raises risks of recession and inequality. Governments are responding with subsidies, reserve releases, and efforts to diversify suppliers, though the conflict's duration will determine the full extent of global damage.
