Crude oil storage tanks are seen from above at the Cushing oil hub, appearing to run out of space to contain a historic supply glut that has hammered prices, in Cushing, Oklahoma, March 24, 2016.
In the previous three weeks, they rose more than 10% on concerns about tight supply.
Higher interest rates increase borrowing costs, which could slow economic growth and reduce oil demand.
Meanwhile, markets worried about Russia's temporary ban on exports of gasoline and diesel to most countries would tighten supplies.
Russian wholesale gasoline prices were down nearly 10% and diesel down 7.5% on Friday on the St. Petersburg International Mercantile Exchange.
