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.

After weathering COVID, the Russia-Ukraine war, and Houthi attacks, the oil market grew "overly sanguine," learning that it was flexible enough to fix most problems. This learned resilience left it unprepared for the Strait of Hormuz closure, a physical problem that market mechanisms cannot easily solve.

In a naval blockade, the real timeline for market impact isn't political rhetoric but the physical limits of onshore storage. Producers are forced to cut output within days or weeks once storage fills, a much shorter timeframe than leaders might suggest for a conflict.

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.

While many fear production shutdowns, a more significant and probable risk is a logistical shock from shipping disruptions. Even modest delays in tanker transit times could effectively remove millions of barrels per day from the market, causing a significant price spike without a single well being shut down.

Despite holding 65-70 days of crude oil reserves, Asian governments and industries begin rationing energy as soon as supply chains tighten. This preemptive action means the economic pain of a disruption is felt much sooner than official inventory levels would suggest, making the reserves a poor gauge of immediate impact.

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.

LNG's market response to a blockade is far quicker than oil's due to storage limitations. With only 2-3 days of spare storage capacity, major LNG producers like Qatar are forced to shut down production almost immediately, while oil producers may have weeks of capacity.

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.
