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 as a massive LNG supply glut promises lower prices, emerging Asian markets lack the physical capacity to absorb it. A severe shortage of regasification terminals, storage, and gas-fired power plants creates a hard ceiling on demand growth, meaning cheap gas alone is not enough to clear the market.

While oil gets the headlines, disruptions to liquefied natural gas (LNG) supply are a more direct threat. LNG is a key energy source for data centers, so price spikes or shortages could derail the massive capital expenditures driving the AI buildout.

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.

Unlike oil, restarting liquefied natural gas (LNG) production is a slow, complex process. The need to cool liquefaction trains from high ambient temperatures to -160°C requires significant time, delaying the return of supply to the market long after a crisis is resolved.

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.

The halt in oil refining cripples the supply of essential byproducts. This includes sulfur (needed for mining and batteries), liquefied natural gas (powering TSMC's chip fabs), and nitrogen fertilizer feedstock. This creates cascading civilizational-level risks far beyond the gas pump.

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.

Severe winter weather in the United States has a direct and significant impact on European energy markets. The cold snap forced a 50% reduction in US LNG feed gas flows, constricting supply to Europe and helping keep prices elevated near €40 amid its own high demand.
