LONDON—Oil prices fell in a volatile market on Tuesday, as a stronger U.S. dollar and economic uncertainty offset the bullish impact of a price cap placed on Russian oil and prospects of a demand boost in China.
Brent crude futures fell 90 cents, or $1.09 percent, to $81.78 a barrel by 1055 GMT. West Texas Intermediate crude (WTI) fell 79 cents, or $1.03 percent, to $76.14.
