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.

Inflation-adjusted data reveals two distinct oil price regimes: a common one around $60-$80 and a rare, high-priced "demand destruction" one above $130. Prices in the $100-$110 range are historically uncommon, suggesting the market snaps into a crisis mode rather than scaling linearly.

Oil is a fundamental component in production, packaging, and logistics for almost every good. Price hikes therefore impact costs across all sectors, including digital-first businesses with physical supply chains, acting as a hidden tax that shrinks profits or raises consumer prices everywhere.

The economic impact of higher oil prices can be quantified: every sustained $10 increase per barrel costs US consumers $3 billion over a year. The recent $30 spike, if it holds, translates to a $90 billion direct cost to consumers, primarily through higher gas prices.

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 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.

While banning US oil exports would initially crash domestic prices, it would quickly cause an overflow of products like diesel in the Gulf Coast. Refineries would then be forced to cut production, ultimately creating shortages of other fuels like gasoline on the East Coast and disrupting the entire system.

An oil supply shock initially appears hawkishly inflationary, prompting central banks to hold or raise rates. However, once prices cross a critical threshold (e.g., >$100/barrel), it triggers severe demand destruction and recession, forcing a rapid policy reversal towards aggressive rate cuts.
