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 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.

An acute supply squeeze in copper is imminent as massive U.S. imports create a severe inventory dislocation. With LME stocks dwindling to critical levels, J.P. Morgan predicts prices must spike to reverse the arbitrage and incentivize the flow of metal out of the U.S. to where it's more needed.

The disruption in the Persian Gulf affects not just the headline commodities of oil and gas, but also crucial dry bulk goods. Outbound fertilizers and aluminum, along with inbound raw materials for production, are significantly impacted, causing spikes in global markets for these specific goods.

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.

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.

A rapid supply increase for metals is unlikely, even with government support. The West outsourced toxic downstream processing to China decades ago due to environmental concerns ('NIMBY'). Reshoring this production requires overcoming the same public hurdles with expensive new technologies, ensuring a long supply response.

The major outage at the Grasberg mine, which supplies 3% of the world's copper, is turning a previously balanced market into a significant deficit for 2025 and 2026. This highlights supply chain fragility, as there were no existing surpluses to absorb the shock.

LNG's market response to a blockade is far quicker than oil's due to storage limitations. With only 2-3 days of spare storage capacity, major LNG producers like Qatar are forced to shut down production almost immediately, while oil producers may have weeks of capacity.
