Doha: Oil prices edged down on Tuesday, weighed by concerns of an economic slowdown driven by prospects of higher US tariffs. Brent crude fell 16 cents, or 0.24%, to $66.58 a barrel, while US West Texas Intermediate crude edged lower 20 cents, or 0.31%, to $64.91 a barrel.

According to Qatar News Agency, US Treasury Secretary Scott Bessent warned that countries could be notified of sharply higher tariffs, despite good-faith negotiations as a July 9 deadline approaches. The tariff rates are scheduled to revert from a temporary 10% level to President Donald Trump’s suspended rates of 11% to 50% announced on April 2.
