The futures contracts of crude palm oil on Bursa Malaysia Derivatives rose tracking gains in CBOT soy oil futures. The most-active December crude palm oil contract on the Malaysian bourse was at 2,740 ringgits (42,326 rupees) per tonne, up 10 ringgits from the previous close. Crude palm oil is used as a substitute for soy oil, and typically their prices move in tandem. A stronger Malaysian ringgit against dollar, however, checked major gains in crude palm oil futures, as it makes exports of palm oil unattractive for domestic sellers. The investors are waiting for data on crude palm oil production, inventories and exports in September, that is expected to be released this week by the Malaysian Palm Oil Board.
