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.

Even a best-case combination of all available workarounds—rerouting pipelines, sanctions relief, and the fastest-ever strategic reserve release—would only mitigate 7 million of the 20 million barrels per day lost from a Hormuz closure. This leaves a practically unsolvable 13 million barrel per day shortfall.

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 recent surge in oil prices to $78 per barrel is not just vague fear. Analyst models suggest the market has priced in an $8-13 risk premium, which corresponds directly to the expected impact of a complete, four-week closure of the Strait of Hormuz, providing a concrete measure of market sentiment.

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 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.

Even if global Strategic Petroleum Reserves (SPRs) were unlimited, their collective maximum release rate is far less than the 20 million barrels per day that flow through the Strait of Hormuz. This physical constraint means SPRs can only soften the blow, not solve the supply crisis, making early release critical.
