US benchmark cocoa futures settled down 1.5 percent at a one-month low Tuesday, pressured by speculative selling amid a rising dollar and bearish technical signals on the price charts, traders said.
The New York Board of Trade's benchmark cocoa contract for December delivery fell $23 to conclude at $1,521 a tonne, the weakest since July 26, after trading from $1,518 to $1,535.
Longer-dated cocoa contracts shed $20 to $22, while the nearby September contract slid $23 to $1,460 a tonne.
