The Persian Gulf

What It Covers

The Persian Gulf's 5,000-year history as a global trade artery, from Mesopotamian maritime routes and Portuguese disruption to the 1908 oil discovery, OPEC's formation, and the region's current control over 20 million barrels of daily oil flow.

Key Questions Answered

• •Strait of Hormuz chokepoint: The Gulf's sole ocean connection measures just 21 miles at its narrowest and handles approximately 20 million barrels of oil daily. Most oil passing through the Strait of Malacca (23 million barrels/day) must first transit Hormuz, giving the region compounding leverage over global energy prices.
• •OPEC sovereignty shift: Before 1960, seven Western oil companies controlled Gulf reserves through contracts signed with local leaders, stalling national development. Iran, Iraq, Kuwait, and Saudi Arabia founded OPEC to reclaim resource sovereignty, transforming themselves from economically subservient states into some of the wealthiest nations on Earth.
• •1973 oil embargo mechanics: Following U.S. support for Israel in the Yom Kippur War, Gulf states imposed an oil embargo paired with 5% monthly production cuts. The resulting supply reduction caused severe U.S. fuel shortages and hours-long gas station queues, demonstrating how production adjustments cascade into everyday consumer prices.
• •Economic diversification strategy: Gulf states are actively redirecting oil wealth into tourism, finance, aviation, technology, and renewable energy sectors to reduce fossil fuel revenue dependence. This deliberate hedging positions the region as a cultural and financial power independent of long-term global hydrocarbon demand trajectories.
