Hormuz Bottleneck Exerts Stranglehold on Global Oil Supply

The Strait of Hormuz is a critical bottleneck in global energy supply, facilitating the transit of around 20-21 million barrels per day of crude oil and refined products.

This narrow waterway's unique vulnerability lies in its inelastic character as a transit constraint. Unlike pipeline infrastructure, maritime chokepoints like Hormuz cannot be bypassed instantly, adding days to weeks of transit time and substantial freight costs.

The key regional exporters whose crude must transit the strait, Saudi Arabia, UAE, Kuwait, Iraq, and Qatar, collectively account for most OPEC+ production capacity. None possess sufficient bypass infrastructure to offset a full Hormuz closure at current export volumes.

War risk insurance premiums have escalated due to Iranian interdiction threats and military escort requirements, compressing refinery margins globally as logistics costs cascade downstream.
