The benchmark September contract on the Bursa Malaysia Derivatives exchange ended MYR11 lower at MYR2,335 a metric ton, off its intraday low of MYR2,328/ton.
Prices have declined 2.7% this week and may fall further next week, as "there's a big possibility we'll see a double-digit rise in July production," a senior trading executive at a Kuala Lumpur-based brokerage said.
Forays by soyoil and crude oil futures into positive territory in Asian trading hours helped cap CPO's losses. But with the Chicago Board of Trade closed Monday for a public holiday, leaving CPO without cues from its main competitor, soyoil, some market participants squared off positions towards the end of trade.
More weakness is likely due to a seasonal increase in palm oil supply in the July-September period, Siegfried Falk, a Hamburg-based analyst and co-editor at Oil World, said.
Still, a sufficiently sharp fall in prices could bring palm olein back to a discount to rival soyoil, after trading at a premium since late last year, shifting buyers' attention away from palm.
"Palm oil may develop a small price discount in the coming weeks (and) regain market share," Falk told Dow Jones Newswires by email.
Palm oil products have lost ground this year as soyoil prices tumbled on the back of strong supply prospects from South American harvests. Palm olein was recently trading at a $20-a-ton premium to soyoil, compared with a discount of more than $100/ton in December.
In the cash market, palm olein for July was offered unchanged at $790/ton and cash CPO at MYR2,440/ton, also unchanged.
