In normal times the Philippines accounts for more than 40 per cent of world exports in the oil, which is used in daily items such as detergents, bath soap and margarine, according to the United Coconut Association of the Philippines.
Super Typhoon Haiyan, which killed or left missing about 8,000 people in November last year, also destroyed or severely damaged about 10 per cent of the nation's coconut trees.
"It will take several years for the supply to normalise (even) if we replant what has been lost during the typhoon," the association's executive director, Yvonne Agustin, told AFP.
"We are of course projecting a reduction in volume this year, and that would lead to increased prices in the world market."
Agustin said coconut oil prices were already "substantially higher" than before the typhoon, with the commodity currently trading at USD 1,445 a tonne.
