The Strait of Hormuz closure severed a critical supply line for US Gulf Coast refineries — not just of crude oil, but of the heavy residual material their specialist processing units need to maximise diesel output. Venezuelan crude has stepped in to fill both roles, and is likely to remain strategically important even after the Strait reopens.
US crude oil imports from Venezuela have risen sharply in recent months and are expected to reach a new high in June, returning to levels last seen in 2017. According to the EIA, Venezuela surpassed Saudi Arabia and Mexico in May to become the second-largest crude supplier to the US after Canada. Venezuelan imports now account for 10% of total US crude imports, compared with 2% at the same time last year, while Canadian volumes have increased from 59% to 65%.

The rise in Venezuelan and Canadian crude imports is partly a structural response to the Strait of Hormuz closure in April, which cut off flows of both crude and heavy fuel oil from the Middle East to the US. It also reflects declining volumes from Mexico and Saudi Arabia, and the need for US refineries to maximise production of diesel and jet fuel as domestic inventories remain low.
After completing the spring maintenance season in late May, US refinery utilisation rates climbed above 95% in early June and are expected to stay elevated throughout the summer driving season.
