The disruption in the Strait of Hormuz isn't a formal closure. Instead, shippers and producers are adopting a "wait and see" approach, halting flows due to reports of damaged ships and skyrocketing insurance premiums, effectively creating a self-imposed blockade.

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.

After weathering COVID, the Russia-Ukraine war, and Houthi attacks, the oil market grew "overly sanguine," learning that it was flexible enough to fix most problems. This learned resilience left it unprepared for the Strait of Hormuz closure, a physical problem that market mechanisms cannot easily solve.

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.

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.

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.

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.
