Dorab Mistry, a veteran trader, said that Indonesia's mandate to use more palm oil will continue in the coming months.
Between now and the end of May, the most-consumed cooking oil can be traded between 3,500 ringgit and 5,000 ringgit a ton.
He said that the war had cast a shadow on the world economy.
In November, Mistry had predicted prices would reach as high as 4,500 ringgit a ton by March.
The war inUkraine has boosted palm oil forecasts.
The price of palm oil rose 1% to 3,918 ringgit on Friday. The vegetable oil fell to 3,336 ringgit in September.
Higher demand from the biofuel industry will support palm prices. Indonesia, the world's biggest palm oil producer, announced on Friday that it would increase its biofuel blend ratio from January.
The new mandate will require the country to use more palm oil in its biodiesel from next year. It's possible that the move will cut palm exports from the country, which accounts for a third of global oil trade.
