Futures contracts of crude palm oil ended lower on the Bursa Malaysia Derivatives due to strength in ringgit against the dollar. Firmness in the Malaysian currency makes palm oil more expensive for buyers holding other currencies. The most-active February contract of crude palm oil on the Malaysian bourse hit an over five-month low of 2,455 ringgits (38,799.88 rupees) per tonne earlier. The contract closed at 2,457 ringgits per tonne, down 0.9% from the previous close.
