When Energy Stops: War, Strait of Hormuz, and Oil Prices

The possibility of an escalation of the conflict between Israel, the US, and Iran has disrupted international energy markets, especially oil contracts. Geopolitical tensions in the Middle East strongly affect oil prices due to the criticality of the Strait of Hormuz, through which about 20% of the world's oil passes. The Strait of Hormuz is a narrow sea passage connecting the Persian Gulf with the Gulf of Oman and the Indian Ocean. A possible closure of the Strait would have dramatic effects on energy markets, as it would create a supply shortage and send prices soaring. Analysts predict that a full closure for a month could add $10-15 per barrel to the price of Brent, while in scenarios of prolonged closure, the price could exceed $110 per barrel. Even a short closure could push prices towards $90 per barrel. The primary economic consequences of a closure of the Strait of Hormuz include a global increase in energy costs, rising fuel prices, rising transportation and logistics costs, and pressure on global economic growth due to increased energy costs.
