Before hostilities erupted, the Strait of Hormuz served as the primary artery for 61% of South Korea’s crude imports and over half of its naphtha supply. As the maritime landscape remains volatile, Seoul’s Ministry of Oceans and Fisheries has designated the Red Sea route as the most realistic contingency available. Saudi Arabia has facilitated this shift by redirecting a significant portion of its export volume to the Yanbu terminal, allowing tankers to bypass the traditional, high-risk corridor.

Despite the recent success of these transits, the strategy faces a precarious future. Houthi forces in Yemen are reportedly posturing to block the Bab el-Mandeb Strait, awaiting tactical authorization from Iran’s Islamic Revolutionary Guard Corps. Such a move would threaten to choke off this secondary route, forcing South Korea to navigate an increasingly narrow window of energy security as the regional standoff persists.
