Oil prices fell, heading for their deepest weekly loss since late June, and are expected to fall by more than 4% this week due to concerns about the impact of tariffs on the global economy, which took effect on Thursday.
Brent crude futures for October delivery fell slightly by 0.1%, or 11 cents, to $66.32 a barrel at 8:04 a.m. Mecca time on Friday.
US Nymex crude futures for September delivery also fell by 0.25%, or 15 cents, to $63.73.
Higher US tariffs on several trading partners took effect on Thursday, and analysts at ANZ Bank said in a note that these tariffs raised concerns about weak economic activity, which could negatively impact demand for crude oil, according to Reuters.
