The world's No.2 palm producer exported 1.02 million tonnes of palm products for Nov. 1-20, down 3.3 percent from 1.06 million tonnes a month ago, cargo surveyor Intertek Testing Services said on Tuesday.
Market players were hoping for higher exports to ease record stocks, which hit 2.51 million tonnes in October. Another cargo surveyor Societe Generale de Surveillance will release its export data later in the day.
"Traders were pretty hopeful for positive export data, although this decline is not really that significant," said Ker Chung Yang, investment analyst at Phillip Futures in Singapore.
"Market participants are also anxious as they wait for the outcome of the European financial meeting," he added, referring to a gathering later on Tuesday where euro zone finance ministers are expected to give a tentative go-ahead for the disbursement of 44 billion euros in emergency loans to Greece.
By the midday break, the benchmark February contract on the Bursa Malaysia Derivatives Exchange had lost 0.3 percent to 2,452 ringgit ($801) per tonne. Prices earlier touched 2,485 ringgit, the highest since Noember 2.
