The United States plans to intercept more vessels carrying Venezuelan oil after seizing a tanker this week, as it steps up pressure on Venezuelan President Nicolas Maduro.
This contrasts with the view of the IEA, which earlier on Thursday implied global oil supply will exceed demand by almost 3.84 million bpd - an amount equal to almost 4% of world demand - next year.
The agency anticipates that rising output and weaker winter demand will accelerate inventory accumulation, contributing to further price declines in the coming months.
Prices for Southern Green Canyon, a crude oil grade produced in the region, strengthened 40 cents on Tuesday to a discount of $2.45 to U.S. West Texas Intermediate crude.
