KUALA LUMPUR: Malaysian palm oil futures logged a near 15% plunge for the week, its biggest weekly drop since mid-March, weighed by weakness in prices of soy oil and a rising production outlook.

The benchmark palm oil contract for September delivery on the Bursa Malaysia Derivatives Exchange slid 88 ringgit, or 1.85%, to 4,656 ringgit ($1,058.18) a tonne, after hitting an intraday low of 4.7%.

For the week, it is down 14.6%, its third straight weekly decline.

“Losses in soybean oil and strong production from the Malaysian Palm Oil Association emerging at the high end of expectations triggered a selloff on the futures this morning,” said Sathia Varqa, co-founder of Singapore-based Palm Oil Analytics. He also expects June 1-25 exports to decline.

The Malaysian Palm Oil Association on Thursday estimated that production during June 1-20 likely rose 15.9% from the month before, traders said.
