Energy Chaos in Asia: How the Iran War is Reshaping Global Supply Chains

The geopolitical landscape of Asia is currently facing an unprecedented energy crisis. Following U.S. And Israeli strikes on Iran, the resulting conflict has triggered a wave of “energy panic” across the continent. With the critical Strait of Hormuz effectively blocked by Tehran, the region’s heavy reliance on Middle Eastern oil and gas has shifted from a strategic preference to a critical vulnerability.

The Chokepoint: The Closure of the Strait of Hormuz

The Strait of Hormuz serves as the primary artery for global energy trade. Its closure has had an immediate and devastating impact on supply volumes. According to reports from the Council on Foreign Relations, the amount of oil passing through the Strait has plummeted to less than 10 percent of pre-war levels.

This disruption is compounded by targeted strikes on vital infrastructure, including:

• The Ras Tanura refinery in Saudi Arabia.
• The Ras Laffan gas processing base in Qatar.
• The Ruwais refinery complex in the United Arab Emirates.

These events have led to a massive drop in Gulf oil production—down 10 million barrels per day compared to March 2025—sending oil futures to $95.

Asia’s Vulnerability and the “Energy Panic”

Asia is the region most exposed to this conflict because it relies most heavily on the shipments passing through the Strait. In 2024, 84% of the oil and 83% of the liquified natural gas (LNG) shipped through the Strait was destined for Asian markets. This has left major economies—including Japan, South Korea, India, Singapore, Taiwan, and Thailand—almost completely dependent on foreign oil with few short-term alternatives.

The consequences are manifesting as acute shortages. In Southeast Asia, governments are facing fuel rationing that threatens to stifle industrial activity. In countries like Indonesia, Myanmar, and the Philippines, the desperation for fuel is evident at gas stations, where long lines and supply shortages have sparked fears of economic shocks and potential violence over limited energy resources.

China’s Strategic Pivot

As the world’s largest energy product importer, China is attempting to navigate the crisis by diversifying its supplier mix. While China previously imported significant amounts of oil from Iran, it is now working to plug energy supply gaps left by the U.S.-Iran conflict, according to Reuters.

While China managed its domestic stockpiles relatively well at the onset of the strikes, the Atlantic Council notes that a prolonged crisis will expose deep vulnerabilities in China’s supply chains and set pressure on its ability to maintain exports to key trading partners.

Global Shifts: Opportunities in the Western Hemisphere

While Asia and Europe struggle with soaring costs and shortages, the crisis is creating a strategic opening for energy producers in the Western Hemisphere. Demand for secure, diversified supplies is intensifying, providing an opportunity for the United States, Canada, Brazil, and Guyana to expand production and attract new investment.

Key Takeaways: The Iran War Energy Impact

• Supply Collapse: Gulf oil production has dropped by 10 million barrels per day vs. March 2025.
• Critical Chokepoint: Oil flow through the Strait of Hormuz is below 10% of pre-war levels.
• Regional Crisis: Asia is the most affected region, with 83-84% of the Strait’s LNG and oil previously bound for its markets.
• Market Reaction: Oil futures reached $95 as countries release reserves to stabilize prices.

Frequently Asked Questions

Why is the Strait of Hormuz so important?

It is the primary transit route for oil and LNG from the Middle East to the rest of the world. Because Asia relies on it for the vast majority of its energy imports, any blockage creates an immediate shortage in the region.

How is China responding to the shortage?

China is switching its supplier mix and utilizing domestic stockpiles to mitigate the impact of the disrupted flows from Iran and the Gulf.

Which other regions are affected?

Europe is facing soaring energy costs and inflationary pressures, while Africa is dealing with higher fuel and fertilizer prices, which are exacerbating food insecurity.

Looking Forward: The current crisis is accelerating a structural shift in global energy policy. As the fragility of Middle Eastern supply routes becomes clear, the world is likely to see a permanent pivot toward diversified sourcing and a renewed emphasis on energy security over short-term cost efficiency.
