Even a best-case combination of all available workarounds—rerouting pipelines, sanctions relief, and the fastest-ever strategic reserve release—would only mitigate 7 million of the 20 million barrels per day lost from a Hormuz closure. This leaves a practically unsolvable 13 million barrel per day shortfall.

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.

The 20 million barrels of oil flowing daily through the Strait of Hormuz represent 20% of global supply. A blockade constitutes a disruption four times larger than the Iranian Revolution or Yom Kippur War embargoes, with no simple replacement.

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.

Energy disruptions in the Strait of Hormuz create a cascade effect far beyond fuel prices. The resulting shortages impact petrochemical and fertilizer production, threatening key inputs for everything from manufacturing and electronics to agriculture and basic services like cooking gas for restaurants.

Petrochemical plants cannot easily switch from using naphtha to ethane as a feedstock. The furnaces are configured differently, and the processes yield vastly different byproducts that require separate post-cracking infrastructure. This technical barrier limits the ability of US ethane to serve as a quick substitute for Middle Eastern naphtha.

The disruption in the Persian Gulf affects not just the headline commodities of oil and gas, but also crucial dry bulk goods. Outbound fertilizers and aluminum, along with inbound raw materials for production, are significantly impacted, causing spikes in global markets for these specific goods.

While Asia holds 65-70 days of crude oil reserves, its Liquefied Natural Gas (LNG) buffer is measured in days, not months. With 40% of its LNG sourced from the Middle East, any disruption presents a more immediate and critical threat to power generation and industrial output than an oil shock.

The Middle East's polyethylene production capacity, about 12% of the global total, is roughly equivalent to all of Europe's annual consumption. A full shutdown of this supply would effectively remove a Europe-sized chunk from the global market, creating a severe shortage.
