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.

In a major supply crisis, temporary measures like storing oil on ships create a false sense of stability. This buffer is finite. Once it's full, the issue rapidly escalates from a logistical challenge to a direct production shutdown, revealing the system's true fragility and causing a much more severe market shock.

A critical but underreported consequence of route disruptions, like in the Strait of Hormuz, is that shipping lines drop containers at the nearest convenient port, not the final destination. This shifts a massive logistical burden onto businesses, who must unexpectedly retrieve cargo from random locations under tight deadlines.

Contrary to narratives about excess demand, the recent inflationary period was primarily driven by supply-side shocks from COVID-related disruptions. Evidence, such as the New York Fed's supply disruption index accurately predicting inflation's trajectory, supports this view over a purely demand-driven explanation.

The impact of an oil supply disruption on price is a convex function of its duration. A short-term closure results in delayed deliveries with minimal price effect, while a prolonged one exhausts storage and requires triple-digit prices to force demand destruction and rebalance the market.

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 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.

It's the volatility and unpredictability within the supply chain environment—rather than the magnitude of a single shock—that can dramatically amplify the inflationary effects of other events, like energy price spikes. This suggests central banks need situation-specific responses.

Even a short-term crisis can create a prolonged aluminum shortage. It takes only a month to shut down a smelter, but restarting that same facility can take six months. This operational asymmetry means that supply is destroyed far more quickly than it can be restored, locking in market tightness.
