Asia Pivots to Coal as Iran Conflict Disrupts Global LNG Supply Chains

The conflict in Iran has sent shockwaves through global energy markets, forcing a dramatic and regressive pivot toward coal across Asia. As the Strait of Hormuz—a critical artery for approximately 20% of the world’s oil and natural gas—becomes a theater of war, the reliable flow of Liquefied Natural Gas (LNG) has been compromised. For nations like India, South Korea, and Thailand, which have spent the last decade positioning LNG as a bridge fuel to transition away from dirtier fossil fuels, the current supply squeeze is a stark reminder of the geopolitical risks inherent in imported energy. This disruption is not merely a logistical hurdle; it is a fundamental challenge to the energy architecture of the world's fastest-growing economic region.

In India, the timing of the conflict is particularly precarious. As the country braces for a summer with peak demand projected at 270 gigawatts—nearly double the total electricity capacity of Spain—the government has little choice but to maximize coal output to prevent widespread blackouts. The reliance on coal is no longer just a policy preference but a survival mechanism for an economy that cannot afford industrial downtime. Similarly, South Korea has moved to lift regulatory caps on coal-fired electricity generation, a move that would have been politically unthinkable just a year ago under its previous climate commitments. These actions reflect a broader regional trend where immediate energy security is now taking precedence over long-term environmental targets.

China remains the most significant player in this shift. Despite leading the world in renewable energy installations, Beijing has continued to build record levels of coal power capacity since 2021 as a strategic buffer. The current crisis validates this dual-track approach in the eyes of Chinese policymakers, who view domestic coal as the ultimate insurance policy against maritime blockades or international sanctions. For the rest of Southeast Asia, including Vietnam and the Philippines, the lack of substantial domestic gas reserves makes coal the only viable default backup when the global LNG market tightens. The U.S., which had been aggressively expanding its LNG exports to the region to counter coal's dominance, now finds its market share threatened by the physical insecurity of transit routes.
