Record tanker rates curb US crude flows to Asia

· Oil & Gas · United States · China

Shipping crude from the U.S. Gulf Coast to China has become so expensive that the economics of the route have all but collapsed, with freight costs reaching as high as $80 million per voyage, according to OilPrice. The driver is the Iran war, which has made tanker voyages so inefficient that vessel availability has crumbled and freight rates have hit record highs. The result is a sharp loss of incentive to move U.S. crude to Asian buyers, who have relied on that supply as an alternative to Middle East barrels. The disruption points to a freight market strained by longer voyages and scarce tonnage, reshaping trade flows rather than simply raising costs. Asian refiners face higher landed costs and a search for replacement supply, while U.S. exporters lose a key outlet for Gulf Coast crude at a time when global prices are already elevated.

Why it matters：Freight economics can reroute global crude trade as effectively as sanctions, and record tanker costs are shifting the balance between U.S. and Middle East supply for Asian refiners.
