A shortage of supertankers, driven by the US-Iran conflict and a South Korean tycoon's big shipping bet, has pushed freight costs to record highs, adding about $26 a barrel (roughly a quarter of WTI's price) to Houston-to-Asia shipments.
The lower availability of supertanks and the record increase in freight rates are calling into question the profitability of some long-distance crude shipments, especially to Asia. Although the market still assigns a low probability to an immediate new historical peak, the bets by the end of 2026 reflect a growing concern about possible logistical constraints.
