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.

Recent supply crises are undermining the gas industry's image as a reliable, affordable, and flexible energy source. The IEA's head warns this 'long shadow' could permanently alter its role in the global energy mix, as trust and perception are eroded regardless of short-term price fluctuations.

The war in Iran is choking the Strait of Hormuz, which handles 20% of global oil. This disruption impacts nearly three times more oil volume than Russia's exports at the start of the Ukraine war, posing a significantly larger threat to the global economy and inflation.

Despite a severe 10 million barrel/day disruption and military escalation, the International Energy Agency (IEA) surprisingly projects that oil supply will be fully restored by June. This optimistic forecast implies a belief that the conflict will resolve relatively quickly, providing a key contrarian view in a pessimistic market.

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.

The ongoing conflict has taken 10% of global oil production offline, a supply disruption of a magnitude unseen by economists in at least 20 years. This is a pure supply-side shock, distinct from demand-side shocks like COVID, creating unique and severe inflationary pressures for the global economy.

Major historical oil price movements were triggered by supply-demand imbalances of just 2-3 million barrels per day. A disruption at the Strait of Hormuz would impact 20 million barrels daily, a scale that dwarfs previous crises and renders standard analytical models inadequate.

While media focuses on Europe and Japan, the IEA head highlights that the biggest victims of the energy crisis are developing countries. Lacking hard currency to compete for expensive oil and gas, they face severe economic strain, potential energy rationing, and a repeat of the 1970s foreign debt spirals.

The global oil supply disruption is not a simultaneous event but a rolling crisis moving from east to west, dictated by shipping times. Asia, heavily reliant on Gulf crude, is already feeling the squeeze, with Africa and Europe next in line, while the U.S. is the most insulated due to longer transit times and domestic production.
