The Worst Oil Shock Since 1973
One week into the US-Iran conflict, global energy markets are experiencing their most severe disruption since the 1973 Arab oil embargo. Brent crude has breached $120/barrel — a 54% increase from pre-conflict levels — driven by the dual impact of Iran's Strait of Hormuz disruption and the loss of Iran's 3.2 million barrels/day production.
The Hormuz Premium
Iran's asymmetric naval operations in the Strait of Hormuz have not closed the waterway but have made it prohibitively expensive and dangerous for commercial shipping. War risk insurance premiums have surged 20-fold, from approximately $50,000 to over $1 million per transit. Several major tanker operators have refused Hormuz transits entirely.
The economic ripple effects extend far beyond crude oil. Approximately 25% of global LNG also transits Hormuz, and Asian spot LNG prices have jumped from $12/MMBtu to over $28/MMBtu — devastating for gas-dependent economies like Japan and South Korea.
Country-by-Country Impact
The disruption impacts nations unevenly:
- Japan — 80% oil import dependence on Hormuz. Has declared a national energy emergency and activated strategic petroleum reserves.
- South Korea — 70% dependence. Seeking emergency supplies from US and Australian sources.
- India — 60% dependence. Oil import bill projected to increase by $90 billion annually. Rupee under pressure.
- China — 40% dependence. Increasing Russian pipeline imports and maintaining discounted Iranian purchases.
