KUALA LUMPUR: Malaysian palm oil futures slumped more than 5% on Monday, snapping a four-session rally as as larger rival Indonesia relaxed its quota for export shipments.

The benchmark palm oil contract for October delivery on the Bursa Malaysia Derivatives Exchange slid 216 ringgit, or 5.04%, to 4,073 ringgit ($915.08) a tonne.

The contract surged 8.4% last week to a more than three- week high.

Top producer Indonesia will retain its domestic sales rule for palm oil to keep local cooking oil prices affordable, a senior official told Reuters.

But the government from Monday will allow exporters to ship nine times the amount sold locally under the rule, up from seven times previously, Septian Hario Seto, a deputy coordinating minister for maritime and investment affairs, said in an interview.

Palm oil is also weighed down by rumours that Jakarta will lower palm oil reference price for August, said Anilkumar Bagani, research head of Mumbai-based vegetable oils broker Sunvin Group.

Exports of Malaysian palm oil products for July rose between 0.8% and 4% from the same week June, according to cargo surveyors’ data.
