Iran War Energy Crisis: How Southeast Asia is Responding

For those of us living and working in Houston, the energy market isn’t just a set of numbers on a screen—it is the heartbeat of the city. Whether you are commuting through the Energy Corridor or managing logistics near the Port of Houston, the current volatility in global crude prices is impossible to ignore. While the conflict in the Middle East feels geographically distant, the closure of the Strait of Hormuz has sent a shockwave directly into our local economy. When Brent crude and West Texas Intermediate (WTI) both surge past the $110 per barrel mark, as they have this Monday, April 6, the ripple effects are felt from the gas stations on Westheimer to the boardrooms of the world’s largest energy firms.

The situation is particularly dire because of the sheer volume of energy that passes through that single choke point. According to 2025 data from the US Energy Information Administration, a staggering 84 per cent of crude oil and 83 per cent of liquefied natural gas (LNG) passing through the Strait of Hormuz are bound for Asian markets. With the strait effectively closed due to the Iran-Israel-US war, the world has lost nearly a fifth of its oil supply. This has pushed prices well beyond the $70 to $85 range we have seen over the last two years, creating an environment of extreme instability for net energy importers.

The Southeast Asian Scramble: From WFH to Nuclear Power

Nowhere is this crisis more visible than in Southeast Asia, where governments are scrambling to maintain basic societal functions amid skyrocketing costs. In Vietnam, the response has reached a level of desperation that mirrors the most severe energy shocks of the past. The Vietnamese trade ministry has gone so far as to call on local businesses to encourage their employees to work from home—not for productivity or health, but as a direct measure to save fuel amid supply disruptions and price surges.

This immediate crisis is forcing a long-term strategic pivot. For decades, Southeast Asia has been a region of atomic ambition without a single watt of nuclear energy produced. However, the vulnerability exposed by the Iran war is acting as a catalyst for a nuclear revival. Analysts suggest that the urgency to uncover alternatives to oil and gas has never been higher. We are seeing a shift where energy security is no longer just an economic consideration but a geopolitical necessity. As Tan-Soo Jie-Sheng, a professor at the Lee Kuan Yew School of Public Policy at the National University of Singapore, noted, the “energy security dimension” has been brought back into sharp focus by these geopolitical shocks.

The acceleration is already manifesting in concrete deals. On March 23, Vietnam and Russia signed an agreement to construct a nuclear power plant in the Ninh Thuan province. This facility, expected to come online in a decade, would mark Southeast Asia’s first modern nuclear power plant. Other nations, including Malaysia, Indonesia, Thailand and the Philippines, have signaled their intent to build nuclear capacity. What we have is a massive shift in regional policy, moving away from a reliance on volatile fossil fuel imports toward a more stable, albeit complex, domestic energy source.

The Intersection of AI and Energy Demand

The push for nuclear energy isn’t just about replacing oil; it is about fueling the future of technology. There is a growing hunger for power driven by the race for artificial intelligence. According to the think tank Ember, We find more than 2,000 data centers across Indonesia, Malaysia, Singapore, Thailand, Vietnam, and the Philippines, with many more in the pipeline. These facilities require immense, constant loads of electricity that traditional grids are struggling to provide.

The International Energy Agency (IEA) projects that Southeast Asia will account for a quarter of the growth in global energy demand by 2035. When you combine this surging demand with the instability of the Strait of Hormuz, the motivation to speed up nuclear efforts becomes clear. Alvie Asuncion-Astronomo of the Philippine Nuclear Research Institute has highlighted that the surge in crude oil prices has significantly increased the motivation for countries to accelerate these efforts.

Overcoming the Ghosts of Energy Past

The path to nuclear energy in the region is not without its historical baggage. To understand the current hesitation and the high stakes, one must seem at the Bataan Nuclear Power Plant in the Philippines. Construction began in 1976, commissioned by President Ferdinand Marcos following the 1973 oil shock. Despite costing roughly $2.2 billion and being completed in 1984, the plant was never used. A combination of government corruption allegations and the global fear following the 1986 Chernobyl disaster ensured that the plant remained dormant.

Today, the region is attempting to break that cycle. The current crisis is pushing these nations to look past the failures of the 1980s and prioritize global market stability and energy independence. The transition is no longer just about low-carbon electricity for corporate ESG goals; it is about survival in a world where a single conflict can choke off 20% of the global oil supply.

Houston Resource Guide: Navigating Energy Volatility

Given my background as an Executive Geo-Journalist covering the intersection of geopolitics and commerce, I know that when global markets swing this violently, the impact hits home in Houston. If the volatility of the Iran war and the subsequent shift in Asian energy demand are affecting your business operations or investment portfolio here in Texas, you cannot rely on general news. You need specialized local expertise to hedge against these risks. To maintain stability, I recommend engaging with these three types of local professionals:

Energy Market Risk Strategists

Look for consultants who specialize in “geopolitical hedging.” You need professionals who can translate events in the Strait of Hormuz into actionable pricing strategies for your local operations. Ensure they have a track record of analyzing WTI and Brent futures specifically during conflict-driven shocks.

Commercial Energy Efficiency Auditors

With prices hovering around $110 per barrel, reducing consumption is the only immediate way to protect your bottom line. Seek out auditors who specialize in industrial-scale efficiency. The criteria for hiring should be their ability to provide a documented ROI on energy-saving retrofits for large-scale commercial properties in the Houston metro area.

Global Supply Chain Continuity Experts

Since the disruption in Asia affects the global flow of LNG and crude, your supply chain may be vulnerable to secondary shocks. Look for specialists who focus on “diversification of sourcing.” They should be able to help you identify alternative suppliers and logistics routes that bypass the most volatile geopolitical choke points.

Understanding the latest energy trends is the first step in protecting your assets from the instability of the global market.
