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.

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.

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.

China has stockpiled approximately three to four months' worth of crude oil. This strategic reserve, combined with its ability to shift from natural gas to coal, gives it significant versatility and reduces its vulnerability to supply disruptions from conflicts in the Straits of Hormuz.

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 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.

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.

While China's 120-day strategic oil reserve provides a significant buffer against disruptions, it has no equivalent for Liquefied Natural Gas (LNG). With nearly one-third of its LNG imports transiting the Strait of Hormuz from Qatar, any regional conflict creates immediate supply pressure, a vulnerability not present in its oil position.
