Asia Reverts to Coal as Iran Conflict Chokes LNG Supply Chains

The Strait of Hormuz remains the world's most critical energy chokepoint, handling roughly 20% of global oil and gas trade. With the conflict in Iran effectively throttling these maritime lanes, the "bridge fuel" strategy—using LNG to transition away from dirtier fossils—has collapsed under the weight of geopolitical risk. For logistics managers and energy procurement officers across Asia, the immediate priority has shifted from carbon intensity to basic availability, sparking a massive logistical pivot back to coal-fired power.

In India, the government is bracing for a peak summer demand of 270 gigawatts, a figure nearly twice the total electricity capacity of Spain. Without reliable LNG imports to fuel gas-fired peaking plants, the nation is ramping up domestic coal production and consumption to prevent widespread blackouts. This move is mirrored in South Korea, where the government has taken the drastic step of lifting regulatory caps on coal-fired electricity generation. This represents a significant policy reversal for Seoul, which had previously been a leader in regional efforts to phase out coal in favor of cleaner alternatives.

Southeast Asia is particularly vulnerable to this supply chain shock. Countries like Thailand, the Philippines, and Vietnam, which have spent the last decade building out expensive LNG regasification infrastructure, are now finding those assets stranded or underutilized. Instead, they are falling back on coal-fired plants that were slated for decommissioning or reduced use. Indonesia, a major global coal exporter, is pivoting its logistics to prioritize domestic supply over international contracts, further tightening the global coal market and driving up prices for other importers.

China continues to play a dual role in this energy crisis. While it leads the world in renewable energy installations, Beijing has also built record coal power generating capacity since 2021 as a deliberate hedge against exactly this type of external shock. The current crisis validates China's "energy security first" approach, likely encouraging other regional players to maintain coal as a permanent backup rather than a phased-out relic. This creates a long-term logistical challenge: maintaining redundant infrastructure for both coal and gas to ensure grid stability during geopolitical upheavals.
