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.

While crude oil shocks dominate headlines, the most acute economic pain stems from shortages of specific, less-substitutable refined products like jet fuel or petrochemical feedstocks. These targeted shortages can cripple specific industries like aviation and plastics much faster than a general rise in crude prices.

Many Asian economies use fiscal policy and reserves to subsidize oil prices for consumers. While this initially dampens the shock, it creates a mixed and delayed effect on inflation and growth, making it difficult for policymakers and investors to predict the ultimate economic consequences.

In a major supply crisis, temporary measures like storing oil on ships create a false sense of stability. This buffer is finite. Once it's full, the issue rapidly escalates from a logistical challenge to a direct production shutdown, revealing the system's true fragility and causing a much more severe market shock.

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.

During major supply disruptions like the Strait of Hormuz closure, quoted oil prices are misleading. If physical barrels are not being delivered, financial quotes don't represent actual business, creating a significant disconnect between financial and physical markets.

Despite holding 65-70 days of crude oil reserves, Asian governments and industries begin rationing energy as soon as supply chains tighten. This preemptive action means the economic pain of a disruption is felt much sooner than official inventory levels would suggest, making the reserves a poor gauge of immediate impact.

The full impact of the Hormuz closure hasn't hit yet. An "air pocket" in global tanker supply is developing. When tankers that departed pre-conflict finally arrive at their destinations, Asian inventories will begin drawing down at an unprecedented 10-15 million barrels per day, triggering a severe, delayed price shock.
