Oil futures declined on Monday, with U.S. benchmark crude posting its lowest settlement since mid-March.
"Disappointing economic numbers out of China continue to be a concern given the country's outsized influence in expected crude demand growth this year," said Robbie Fraser, manager, global research & analytics at Schneider Electric.
"Additionally, trading continues to keep a close eye on U.S. Federal Reserve policy, where support for the dollar typically translates to weaker crude prices."
July West Texas Intermediate crude fell $3.05, or nearly 4.4%, to settle at $67.12 a barrel on the New York Mercantile Exchange.
That was the lowest price for a front-month contract since March 17, according to Dow Jones Market Data.
