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.

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.

Financial futures like Brent and WTI are lagging indicators of the current oil crisis. Physical markets, which reflect immediate supply-demand, are already showing extreme stress with prices like Oman crude over $180 and Singapore jet fuel over $200. These physical prices are a leading indicator of where futures are headed if the crisis persists.

Unlike tariffs, which are passed through business costs and can be partially absorbed, an oil shock immediately impacts consumers at the gas pump. This direct hit means the financial pain is felt faster and more universally by households, leading to a quicker and more pronounced change in spending behavior.

Fuel represents a much larger portion of a low-cost carrier's expenses (about a third) compared to legacy carriers (a fifth). This structural difference makes budget airlines significantly more vulnerable to fuel price shocks from geopolitical events, forcing them to take more drastic measures.

Focusing on crude's rise to $100/barrel misses the real story. Prices for refined products consumed by industries and travelers, such as diesel and jet fuel, have nearly tripled. This massive divergence reveals that the true economic pain is concentrated downstream from the oil well.

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.

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.
