The closure of the Strait of Hormuz is sending shockwaves through global energy markets, forcing buyers to scramble for alternatives as oil and gas shipments grind to a halt. The ongoing Iran conflict has already pushed coal demand higher, as nations locked out of the Persian Gulf turn to the dirtiest fossil fuel to keep lights on. The crisis underscores just how fragile the world's energy supply chains really are.
Global energy markets in turmoil
The strait, a narrow chokepoint between the Persian Gulf and the Gulf of Oman, handles about a fifth of the world's oil and a quarter of its liquefied natural gas. With Iran's military blocking passage, tankers are idling, refineries are cutting output, and spot prices for crude have jumped. No one knows how long the blockade will last — but every day it drags on, the damage deepens.
Energy traders are struggling to reroute shipments from other regions, but spare capacity is thin. Saudi Arabia and Iraq can't get their crude out. Qatar's LNG is stuck. The result is a fragmented market where buyers in Asia and Europe are paying a premium for whatever barrels they can find — often from faraway producers in the Americas or West Africa.
Coal demand surges
With oil and gas supplies choked off, coal is making a comeback. Countries that have spent years trying to phase out the fuel are now burning more of it. India and China, already the world's top coal consumers, are increasing purchases from Australia, Indonesia, and Russia. Even some European utilities, normally eager to cut emissions, are firing up mothballed coal plants to cover the shortfall.
The surge is pushing coal prices higher — and raising questions about climate goals. The irony isn't lost on anyone: a conflict in the Middle East is undoing years of progress on decarbonization, at least in the short term. But for now, energy security trumps environmental pledges.
Supply chain vulnerabilities exposed
The Strait of Hormuz crisis is a stark reminder of how dependent the world is on a single narrow waterway. Pipelines and alternative routes exist — such as the Saudi-led East-West pipeline or the UAE's Habshan-Fujairah system — but they can't replace the strait's volume. The closure has laid bare a structural weakness in global energy infrastructure: too much supply concentrated in one place.
Governments are now talking about diversifying energy sources and building strategic reserves. But those are long-term fixes. Right now, the immediate question is how long the strait stays closed. If it's weeks, markets might absorb the shock. If it's months, the economic fallout could be severe — and coal's comeback might not be a temporary blip.
