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 war in Iran is choking the Strait of Hormuz, which handles 20% of global oil. This disruption impacts nearly three times more oil volume than Russia's exports at the start of the Ukraine war, posing a significantly larger threat to the global economy and inflation.

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.

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.

While options like releasing strategic reserves and tapping Saudi spare capacity exist, they are temporary stopgaps. These measures fall short of replacing the 20 million barrels per day—over 20% of global production—that flow through the Strait of Hormuz, making its security the paramount issue.

While global spare oil capacity exists as a buffer, it is heavily concentrated in Saudi Arabia, the UAE, and Kuwait. During a conflict, if the Strait of Hormuz is effectively closed, this capacity becomes physically trapped and cannot be deployed to global markets, nullifying its role as a price stabilizer.
