Crude oil prices fluctuated amid concerns over U.S. tariffs on Canadian and Mexican imports but are set to end the week lower.

Oil prices were on track for weekly losses of roughly 2% amid uncertainties over looming U.S. tariffs. Brent crude was down 0.2% at $75.72 a barrel, while WTI fell 0.1% to $72.66 a barrel in volatile trade.

Oil prices fell on Wednesday, with the U.S. benchmark settling at its lowest year to date, after domestic crude stockpiles in the world's top petroleum producer and consumer rose more than expected last week.

Oil futures ticked lower Friday and were on track for weekly losses as traders awaited a decision by President Donald Trump on tariffs on imports from Canada and Mexico.
