The Hormuz Bottleneck: A Global Energy Crisis in the Making

Most importantly, the Strait of Hormuz enables the transportation of roughly 20 million barrels daily (bpd) of petroleum liquids, making it the most important marine artery in the world energy business. Representing about 20% of the worldwide oil consumption, this book makes any disturbance to this small path a disastrous menace to world economic stability. Oil flows averaged 20.1 million bpd in the first quarter of 2025 alone—including 14.2 million bpd of crude oil—therefore highlighting the great magnitude of the energy resources going through this volatile choke point.

Asia accounts for more than 80% of all oil shipped through the strait; thus, dependence on this waterway is rather skewed. With reliance on the passage for roughly 75% of its total oil imports—mostly from Saudi Arabia and the UAE—Japan remains the most fragile major economy. Other local powers are similarly exposed: South Korea relies on the strait for 60% of its supply, while India and China both witness nearly half of their overall oil imports—amounting to more than 7.5 million combined bpd—at immediate risk during times of regional conflict.

Western countries, by contrast, keep a much lower direct reliance on the strait even if they remain vulnerable to the ensuing worldwide pricing spikes. While Europe's reliance ranges from 10% to 20% as it keeps changing its energy sources in reaction to Russian sanctions, the United States has reduced its exposure to just 7-8% of all oil imports. Though this direct volume is lower, the sheer magnitude of the 5.4 million bpd headed for China and millions more for Japan and India guarantees that a closing of the strait would cause a systematic shock to the global energy supply network.
