Historical Context

The Iran-Iraq War, which began in 1980, heightened tensions in the Strait of Hormuz, a critical passage for global oil transport, with over 20% of the world's oil trade transiting through it. In 2026, following U.S. and Israeli military actions against Iran, the strait faced significant disruptions, impacting global energy markets and highlighting its strategic importance amid ongoing geopolitical conflicts.
