Which strait is a strategic chokepoint for global oil shipments, with nearly one-third of seaborne crude oil passing through it?

• A. Strait of Hormuz
• B. Bab el-Mandeb Strait
• C. Strait of Malacca
• D. Bosphorus Strait

Answer: (A)

Global oil shipments rely on a few narrow passages where a lot of oil must move through a small area, so any disruption there can have outsized effects on world markets. The Strait of Hormuz sits between Iran and Oman and serves as the only sea outlet from the Persian Gulf to the open ocean. Because so much of the world’s crude comes from the Persian Gulf, a large portion—estimates are around one‑third of seaborne crude—flows through this single, relatively narrow channel. Its bottleneck nature makes it a strategic chokepoint: even a temporary disruption from conflict, sanctions, or accidents can constrain supply, drive up shipping costs, and influence global oil prices. The other straits are significant for regional or global trade, but they do not alone carry the same scale of crude as Hormuz. Bab el-Mandeb handles traffic between the Red Sea and the Arabian Sea, Malacca is a major route for Asian-bound trade, and the Bosphorus is a critical link between Europe and Asia, but none is widely recognized as carrying roughly a third of seaborne crude oil the way Hormuz does.
