The latest U.S. oil inventory data this week also raised fears about a slowdown in the world's biggest economy, with crude stocks having climbed to their highest since June 2021. Nevertheless Brent and WTI have jumped more than 5% so far this week, reversing most of last week's losses as concerns about further sharp interest rate hikes by the U.S. Federal Reserve have eased.
The lower rate hike expectations drove the dollar down, which in turn supported oil prices. A weaker greenback makes oil cheaper for holders of other currencies and often sparks buying. The market has also been buoyed by Saudi Arabia's move to increase its official crude sales prices to Asia, seen as signalling a demand recovery in China.
Analysts said U.S. inflation data on Feb. 14 will be key to risk sentiment and the dollar's direction.
"As inflation declines across Europe and the U.S., risks
remain elevated that central banks will need to still deliver
more tightening than what markets are pricing in," OANDA analyst
Edward Moya said in a note.
