Every 10 days the Strait of Hormuz is closed, a 200-million-barrel physical gap is created in the global oil flow. This is not a temporary kink but a massive hole in the supply chain that will take months to resolve and normalize, even long after transit resumes.

A dangerous disconnect exists between oil futures prices, which seem muted, and the physical market. Experts warn of a catastrophic global supply shortage if the Strait of Hormuz remains closed, highlighting a significant tail risk that financial markets are currently underpricing.

The 20 million barrels of oil flowing daily through the Strait of Hormuz represent 20% of global supply. A blockade constitutes a disruption four times larger than the Iranian Revolution or Yom Kippur War embargoes, with no simple replacement.

The recent surge in oil prices to $78 per barrel is not just vague fear. Analyst models suggest the market has priced in an $8-13 risk premium, which corresponds directly to the expected impact of a complete, four-week closure of the Strait of Hormuz, providing a concrete measure of market sentiment.

The Middle East conflict has moved beyond risk to a physical blockade of the Strait of Hormuz. With commercial tankers no longer transiting, nearly 20% of global oil is cut off from markets. This supply disruption, not just a risk premium, is driving oil prices toward $100/barrel.

The impact of an oil supply disruption on price is a convex function of its duration. A short-term closure results in delayed deliveries with minimal price effect, while a prolonged one exhausts storage and requires triple-digit prices to force demand destruction and rebalance the market.

Major historical oil price movements were triggered by supply-demand imbalances of just 2-3 million barrels per day. A disruption at the Strait of Hormuz would impact 20 million barrels daily, a scale that dwarfs previous crises and renders standard analytical models inadequate.

The full impact of the Hormuz closure hasn't hit yet. An "air pocket" in global tanker supply is developing. When tankers that departed pre-conflict finally arrive at their destinations, Asian inventories will begin drawing down at an unprecedented 10-15 million barrels per day, triggering a severe, delayed price shock.

A prolonged blockade of the Strait of Hormuz would remove up to 16 million barrels of oil per day. This scale is so massive that government strategic reserves are inadequate to fill the gap. The only mechanism to rebalance the market would be catastrophic demand destruction.
