How Big Is the Energy Shock From the Iran War?

Why It Matters

The shock curtails a combined 35% of critical oil and gas supply, driving price volatility and forcing governments and businesses to accelerate diversification strategies.

Key Takeaways

• Strait closure cuts 15% of global oil supply
• Qatar's LNG shutdown removes ~20% of world gas output
• Europe faces dual shortfall after losing Russian gas and LNG
• Gulf wells being shut‑in; restart may take weeks or longer
• Liquefaction plants need month‑plus to cool and resume operations

Summary

The video examines the magnitude of the energy supply shock triggered by the Iran‑Israel conflict, focusing on the closure of the Strait of Hormuz and Qatar’s decision to halt liquefied natural gas production.

Analysts note that the strait blockage eliminates roughly 15% of worldwide oil output, while Qatar’s LNG shutdown removes about 20% of global gas supply. Europe, having recently weaned off Russian pipeline gas, now confronts a double deficit that is reverberating through global markets.

Experts cite concrete examples: Gulf operators are “shutting in” wells because storage tanks are full, and restarting them can take weeks. Qatar’s liquefaction trains behave like a refrigerator after a blackout—cooling to –160 °C cannot be achieved instantly, implying at least a month before pre‑war output levels resume.

The prolonged disruption threatens higher energy prices, accelerates the search for alternative supplies, and may reshape long‑term investment in diversification and strategic reserves for both Europe and oil‑importing nations.

Original Description

The Gulf war has brought traffic in the Strait of Hormuz almost to a halt, sparking an energy shock that will reverberate around the world. Our editors analyse the impact on this week’s Insider episode.
