South Africa to Australia: Why coal profits are surging during Iran war

Crude oil and natural gas supplies have been disrupted worldwide by the United States-Israel war on Iran, but one energy sector appears to be cashing in – coal.

This week, South Africa’s thermal coal producer Thungela Resources said it had doubled its half-year profits as the war has forced more countries to buy the fuel.

Although abundant and relatively cheap to produce, coal is considered one of the dirtiest fossil fuels.

Mining it causes water pollution, and burning it releases enormous amounts of carbon into the atmosphere, which contributes to global warming.

In recent months, several countries, especially in Asia, have reversed or delayed promises to scale back on coal production.

Global coal consumption was already rising in 2025 with the Eurasia region and the US using the fuel to power artificial intelligence data centres, according to the World Bank.

The US-Israel war on Iran has triggered a global energy crisis. Soon after strikes on Tehran began on February 28, Iran closed the Strait of Hormuz, through which about one-fifth of the world’s oil and liquefied natural gas (LNG) supplies were shipped during peacetime.

Its closure has reduced oil and gas supplies and caused oil prices to soar, prompting many countries to fall back on the most readily available alternative to keep the power on – coal.
