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 oil supply shock isn't simultaneous. It's a rolling disruption dictated by shipping times, hitting Asia first due to its reliance on Gulf crude and shorter voyages (10-20 days). Africa, Europe, and finally the U.S. (35-45 days) feel the impact sequentially, buffered differently by regional inventories.

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.

The Iran crisis has caused the largest physical logistics disruption in the history of the modern oil market. However, it has not led to the largest price dislocation. This disconnect highlights the market's initial belief that the disruption would be short-lived, a view that is now being tested.

The physical impact of a supply disruption isn't immediate. It takes about two weeks for tankers from the Middle East to reach Asia and over three for Europe. This lag means consumers and industries only start feeling the actual shortage weeks after the event, despite immediate price reactions.

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.

A colonial-era demarcation still defines oil markets. Asia ('East of Suez') relies heavily on Middle Eastern oil and feels disruptions almost immediately. Europe and the Americas ('West of Suez') are more detached, experiencing the crisis with a significant time lag.

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.
