Data over the last 40 years shows that the percentage change in gross world product moves in lockstep with the percentage change in gross energy consumption. A 5-10% fall in energy supply, as threatened by the conflict, will almost certainly trigger a 5-10% fall in global GDP.

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.
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.
Even a brief closure of the Strait of Hormuz has immediate, lasting effects. Shutting in millions of barrels of oil and LNG damages production facilities, which can take over 60 days to bring back online, ensuring a recession even if the conflict ends quickly.
The current energy disruption involves a loss of 12 million barrels of oil per day, exceeding the combined total of the 1973 and 1979 crises. Additionally, natural gas losses are greater than during the Russia-Ukraine crisis, making this the largest energy security threat in history.
IEA Executive Director Fatih Birol quantifies the current energy crisis, stating that the loss of supply is greater than the 1973 oil crisis, the 1979 oil crisis, and the 2022 Russian gas crisis put together, making it an unprecedented global security threat.
Re-establishing normal energy flows is not like flipping a switch. It can take months to recover even if a conflict ends quickly. Furthermore, if infrastructure like LNG plants or oil wells is damaged, the supply reduction and economic pain can last for years.
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.
The loss of Persian Gulf oil is a fatal blow to the manufacturing-based economies of Europe and China. China lacks energy alternatives, and Europe's green tech isn't sufficient. This single event could trigger the simultaneous collapse of the world's two largest manufacturing zones.
Economic growth is a direct function of the reduction in the price of energy. Nations with access to cheap, locally available energy are almost uniformly wealthy, regardless of their system of governance, while those without it are almost uniformly poor.
The ongoing war in the Middle East, particularly its impact on energy prices via potential disruptions like the closure of the Strait of Hormuz, is now the primary factor shaping the global macro outlook. This negative supply shock significantly increases the probability of a global recession.
