History

Historical Context

The Iran-Iraq War began on September 22, 1980, when Iraq invaded Iran, aiming to seize the oil-rich Khuzestan province. This conflict led to a 50% drop in Iran's oil production, disrupting global supplies and escalating prices. Today, renewed tensions in Iran echo the economic instability of that era, as rising oil prices threaten global growth and prompt cautious monetary policies from central banks.
