History

Historical Context

The Iran-Iraq War, which began in September 1980, significantly disrupted oil shipments through the Strait of Hormuz, a vital global transit route. During this conflict, around 1,000 oil tankers were attacked, causing global oil prices to soar. Today, Iran's threats to restrict access echo these historical tensions, highlighting the strait's ongoing strategic importance for international energy security, with 20% of the world's oil passing through it.
