IEA forecasts record global coal demand in 2026 as Hormuz Strait closure forces nations to replace oil and gas

The Quick Take

• The IEA's mid-year update forecasts record global coal demand in 2026 driven by Hormuz Strait trade disruptions
• Countries are turning back to coal as oil inventories deplete and renewable capacity expansion remains too slow to compensate
• Natural gas prices have risen sharply due to Hormuz restrictions, making coal the lowest-cost substitute for power generation in affected markets

The International Energy Agency's record coal demand forecast for 2026 represents a stark reversal of the energy transition trajectory projected before the Hormuz Strait closure. The Strait channels roughly 20 percent of global oil shipments and 30 percent of LNG flows, creating an acute energy security shock that governments are addressing by reopening coal plants, extending retirement schedules, and accelerating thermal coal procurement. This is the most significant geopolitical disruption to the global energy mix since Russia's invasion of Ukraine in 2022 rerouted European energy supply chains.

Record coal demand is structurally bullish for thermal coal producers including Glencore, Arch Resources, Whitehaven Coal, and India's Coal India Limited. Asian utilities most exposed to the LNG price spike — South Korean KEPCO, Japanese JERA, and Taiwanese power companies — are the primary incremental demand drivers behind the IEA forecast revision. Seaborne thermal coal spot prices historically track LNG spot price volatility with a three to six month lag, suggesting elevated coal prices could persist well into 2027 if Hormuz disruptions continue.

Watch the IEA monthly Oil Market Report for upward revisions to the coal demand forecast as cumulative Hormuz closure duration data accumulates. The diplomatic timeline for Iran-US framework talks is the single most critical variable: any credible Hormuz reopening signal would abruptly collapse the coal demand thesis and thermal coal prices simultaneously. Central bank responses to commodity-driven inflation across Asia — particularly RBI, Bank of Korea, and Bank of Japan — represent the transmission mechanism through which energy commodity shocks convert into equity market volatility.
