South Korea, one of the world’s largest oil importers, remains heavily dependent on Middle Eastern crude despite the rise of U.S. shale oil exports. Analysts attribute this to long-term contracts, refining infrastructure compatibility, and geopolitical considerations. Over 70% of South Korea’s oil imports in 2023 came from Saudi Arabia, Kuwait, and Iraq, according to Korea National Oil Corporation data.
Industry sources note that Middle Eastern crude’s chemical composition better suits South Korean refineries, which were designed to process heavier grades. “Switching to lighter U.S. shale would require billions in retrofitting costs,” said a refinery executive speaking anonymously due to contractual sensitivities.
Geopolitical factors also play a role. “The U.S. prioritizes energy security partnerships with NATO allies over Asian markets,” noted Dr. Lee Min-ho, an energy analyst at Seoul National University. Recent OPEC+ production cuts have further incentivized South Korea to maintain stable Middle Eastern supply lines.
Looking ahead, analysts suggest diversification may accelerate if U.S.-China tensions disrupt Asian supply chains. However, most predict Middle Eastern oil will dominate South Korean imports through at least 2030 due to existing infrastructure investments.
