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.

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 global oil market has two parts: pipeline and seaborne. Price volatility and formation are dominated by the more flexible seaborne market, which can be redirected to meet global demand, making it the critical component for setting prices, despite only being 60% of total consumption.

Despite being a net oil exporter by volume, the U.S. is not isolated from global price shocks. Its market is deeply integrated through massive flows of both imports and exports. In the global seaborne market, there is effectively one oil price that all participants, including the U.S., must pay.

The market impact from the expected, but unrealized, loss of 3 million barrels/day from Russia was immense. The current Strait of Hormuz disruption is four to five times larger at 14 million barrels/day. This scale of shortage is historically unprecedented, meaning past events are poor guides for predicting market outcomes.

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.

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.

The conflict's primary impact on oil is not that supply is offline, but that its transport through the Strait of Hormuz is blocked. This distinction is key to understanding price scenarios, as supply exists but cannot be delivered.

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.
