Oil prices fell to a near five-month low on Tuesday on a stronger U.S. dollar and demand concerns, putting the market down for a fourth day in a row on doubts over OPEC+ announced voluntary supply cuts last week. "The OPEC+ deal did little to support prices and given the (four) days of declines that followed it, traders are clearly very unimpressed," said Craig Erlam, senior market analyst UK & EMEA, at data and analytics firm OANDA. Brent crude oil futures fell 83 cents, or 1.1%, to settle at $77.20 a barrel, while U.S. West Texas Intermediate crude (WTI) ended 72 cents, or 1.0%, lower at $72.32.
