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 market's immediate reaction to the Middle East conflict has been to price in higher inflation due to spiking energy costs. However, it has not yet priced in a significant economic growth shock. This second-order effect, the "shoe that's left to drop," represents a major future risk if the conflict persists.

Even a brief closure of the Strait of Hormuz has immediate, lasting effects. Shutting in millions of barrels of oil and LNG damages production facilities, which can take over 60 days to bring back online, ensuring a recession even if the conflict ends quickly.

The ongoing conflict has taken 10% of global oil production offline, a supply disruption of a magnitude unseen by economists in at least 20 years. This is a pure supply-side shock, distinct from demand-side shocks like COVID, creating unique and severe inflationary pressures for the global economy.

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.

A single major geopolitical event, like the discussed Iran conflict, can simultaneously and rapidly reverse numerous positive, interconnected economic indicators. This demonstrates the extreme fragility of prevailing market storylines, flipping everything from energy prices and equity performance to inflation and central bank policy.

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 Moody's machine learning model, which analyzes leading economic indicators, had already calculated a 48.6% probability of recession *before* the Iran conflict began. The primary driver for this high reading was a deteriorating labor market, indicating underlying economic weakness.
