The cost of hiring Very Large Crude Carriers (VLCCs) has surged to unprecedented levels, with rates for a benchmark route from the Persian Gulf to Asia hitting a record $1.1 million per day, a 12-fold increase in a few months. Some VLCC earnings have even exceeded $1.2 million a day. This dramatic increase is largely attributed to a shortage of available supertankers and geopolitical factors, including the U.S.-Iran conflict and strategic vessel acquisitions by companies like Sinokor Group.

This spike in shipping costs is profoundly impacting the global oil market. Moving a cargo from Houston to Asia now adds approximately $26 per barrel, or $52 million per cargo, to the cost of supplying the world's largest crude-importing region. This additional cost is roughly a quarter of the price of West Texas Intermediate futures, a significant jump from pre-conflict levels where shipping accounted for only a tiny fraction of the total cost. Analysts at Kpler suggest that these elevated freight costs could become "self-limiting" by closing arbitrage routes and reducing demand for expensive long-haul barrels.

The soaring rates are making long-distance crude shipments uneconomical, prompting refiners to seek supplies closer to home. For example, U.S.-Asia flows have decreased, and a Japanese refiner recently purchased Alaskan crude due to its shorter sailing distance. European refiners are also bidding up the North Sea market to minimize shipping expenses. The high freight costs are raising concerns among oil traders that it may become unprofitable for some refiners to process crude into fuels, thereby deterring purchases of long-haul cargoes even amid strong demand for diesel and gasoline.

The surge in supertanker rates has also pushed up earnings for smaller vessels, with Suezmaxes now commanding over $300,000 a day, rates typically seen in war zones. While the current bonanza is minting fortunes for a small group of shipowners, the increased costs are ultimately borne by the global economy. Experts like Saad Rahim, chief economist at Trafigura Group, and Xavier Tang, senior market analyst at Vortexa, highlight that freight, which was once a minor component, is now a much bigger factor in the delivered cost of oil, creating significant logistical challenges and affecting end buyers.
