US coal producers are racing to capitalize on surging demand from Europe and Asia due to the Iran crisis, but escalating diesel prices and logistical hurdles threaten their efforts. The Strait of Hormuz blockade has forced Asian and European utilities to turn to coal-fired power, creating a $25 billion opportunity for exporters. However, diesel costs—already up 48% since the conflict began—are eating into profits, with transport expenses rising sharply for US shippers. Core Natural Resources CEO Jimmy Brock warned that higher fuel prices are making exports “frustratingly” expensive, particularly for firms like his that rely on domestic production.

The Trump administration’s push to revive coal exports via an April executive order has done little to offset trade war losses, as China’s retaliatory tariffs slashed US shipments by 18% in 2025. While Peabody Energy has seen success shipping Australian coal to Asia amid liquefied natural gas shortages, domestic producers face a geographical disadvantage compared to closer competitors. Analysts note that US coal’s landlocked location forces reliance on costly rail and truck transport to East Coast ports, where shipping costs to China have spiked 55%.

Peabody’s Australian operations, however, have thrived, with Newcastle coal prices surging 22% since the Iran crisis began. Yet, the company’s broader US export ambitions remain stalled due to locked-in domestic supply contracts and insufficient production capacity. “There’s a tug of war between domestic demand and global sales,” said Wood Mackenzie analyst Tony Knutson.

While a potential Hormuz reopening could dampen coal’s short-term edge, analysts argue the crisis has exposed vulnerabilities in global energy security, potentially reshaping long-term trade dynamics. “The war has highlighted risks of over-reliance on Persian Gulf supplies,” said McCloskey by OPIS analyst Andy Blumenfeld, suggesting the shift toward diversified energy sourcing may persist beyond the conflict.”
