Middle East Uncertainty Forces Oil Importers to Diversify Supply Routes

Major oil importers are being forced to adapt their supply routes due to ongoing tensions in the Middle East, particularly involving Iran. This shift is leading to a more dispersed network of energy corridors that prioritize security and resilience over cost efficiency.

The crisis has disrupted Gulf exports, with total volumes shipped from March through July 40% lower than a year earlier. Japan, one of the world's top oil importers, has been particularly affected. Until recently, over 90% of its crude oil came from Middle Eastern suppliers via a relatively straightforward 21-day voyage.

However, with Middle East supplies dwindling, Japan turned to North American sources, importing over 4.5 million metric tons of US crude between March and June, a 400% increase year-over-year. This change comes at a cost, with journey times nearly nine days longer and sharply higher shipping costs.

Other major oil importers, such as South Korea and India, have also diversified their supply sources, increasing flows from the Americas and Africa. China has relied on its strategic oil reserves to buffer itself against the impact of the crisis but is expected to increase crude imports later in 2026.
