Asian refineries, facing a potential cutoff of crude from the Strait of Hormuz, are reducing processing rates to prolong operations. This immediate reduction in the supply of refined products like jet fuel causes their prices to spike before the full impact of the crude oil shortage is felt globally.

In a severe supply shock, demand destruction isn't about wealthy consumers driving less. Instead, lower-income countries are priced out of the market entirely, unable to attract scarce barrels. This transforms a price problem for developed nations into an outright physical shortage for developing ones.

In a naval blockade, the real timeline for market impact isn't political rhetoric but the physical limits of onshore storage. Producers are forced to cut output within days or weeks once storage fills, a much shorter timeframe than leaders might suggest for a conflict.

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.

Despite producing as much oil as it consumes, the US is not immune to price shocks. Consumers cut spending immediately, while producers delay new investment due to price uncertainty. This timing mismatch ensures oil shocks remain a net negative for the US economy over a 12-18 month horizon.

Despite his stated goal of lowering oil prices, President Trump's aggressive sanctions on Venezuela, Iran, and Russia have removed significant supply from the market. This creates logistical bottlenecks and "oil on water" buildups, effectively tightening the market and keeping prices higher than they would be otherwise.

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 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.

The US primarily produces light crude oil, but its refineries are configured for heavier crude. The country exports its light crude and imports heavy crude to match its refining capacity. An export ban would create a massive mismatch and strand domestic production.
