Supertanker Shortage Drives Oil Shipping Costs to Record Highs

A global shortage of supertankers has driven oil shipping costs to record highs, threatening the economic viability of long-haul crude trades. The surge is primarily driven by the conflict between the United States and Iran, which has forced vessels to take longer routes around Africa or engage in complex cargo swaps near Oman. A large-scale wager by a South Korean tycoon also contributed to rising rates before the conflict began.

Shipping costs for cargoes from Houston to Asia have increased by approximately $26 per barrel. This price hike has led some refiners to prioritize shorter-haul supplies, such as Alaskan crude for Japanese processors. Data from Vortexa shows a corresponding decline in oil flows between the United States and Asia.

While shipowners are seeing record profits and tanker equities have reached nearly $70 billion, oil traders warn of long-term risks. Trafigura characterized the current cost of moving oil as unprecedented, and Kpler warned that prohibitively expensive freight may eventually close arbitrage routes. These costs could deter refiners from producing fuels despite strong global demand for diesel and gasoline.
