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.

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.

Iran's success in disrupting global shipping validates the PRC's belief that the U.S. and its allies lack the resilience to withstand economic pressure on key maritime chokepoints. This bolsters China's confidence regarding a potential future Taiwan Strait crisis.

Despite government actions like tapping strategic reserves and using alternate pipelines, these measures can only offset about 9 million barrels per day of the 20 million lost from the Strait of Hormuz. This leaves a massive 11 million barrel per day shortfall, dwarfing previous supply shocks.

China maintains a strategic petroleum reserve covering over 120 days of imports, exceeding the 90-day international standard. This massive stockpile is not just for economic stability but is a key national security measure, driven by long-standing fears that the U.S. Navy could cut off its seaborne oil supplies during 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.

China's extreme reliance on oil from Iran and Venezuela (20% of domestic consumption) makes it the party most hurt by the conflict. This gives the US leverage, pressuring Xi Jinping to negotiate a resolution to secure China's energy supply and stabilize its economy.

Faced with geopolitical uncertainty in key supplier nations, China employs a dual strategy for energy security. It has built a massive oil stockpile providing 120 days of cover for supply disruptions. Concurrently, it's rapidly electrifying its transport sector to reduce its long-term dependence on imported oil.

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.
