Major Straits of the World

Straits are narrow passages of water that connect two larger bodies of water and are bordered by land on two sides. They hold significant geopolitical, strategic, and economic importance due to their role in international navigation and maritime trade.
Strategic Importance of Straits
- Global Trade: Over 80% of global trade by volume is conducted through maritime routes, many of which pass through key straits.
- Chokepoints: Straits act as chokepoints—control over them can influence global energy supplies and military movement.
- Geopolitics: Nations often contest straits due to their location and strategic value in international diplomacy and security.

Key Straits and Oil Transit
Some straits are globally crucial for oil and gas shipping:
- Strait of Hormuz: Around 20% of the world’s petroleum passes through it.
- Strait of Malacca: Major East Asian trade route, especially for China and Japan.
- Bab el-Mandeb: Connects Europe with Asian oil markets via Suez Canal.
Straits and International Law
- Governed under the United Nations Convention on the Law of the Sea (UNCLOS).
- Ships enjoy transit passage rights in straits used for international navigation.
Interesting Facts
- Gibraltar, Bosporus, and Hormuz have historically been flashpoints in global conflicts.
- The Bering Strait is only ~85 km wide, and frozen in winter, making it theoretically crossable.
- The English Channel was used for the D-Day invasion during WWII.
Conclusion
Major straits of the world are not just geographical features but are of immense strategic, economic, and political importance. In the era of global trade, energy security, and regional rivalries, control and safe navigation through these straits have become essential for international stability.
