VEGOILS — Malaysian palm oil falls on weaker rival oils, export data eyed

(Update with midday break prices, adds trader's comment) JAKARTA, Oct 15 (Reuters) — Malaysian palm oil futures eased on Thursday, snapping a three-session rally as weaker rival vegetable oils on the Dalian and Chicago markets weighed on prices, while traders awaited export data for fresh demand cues. The benchmark December palm oil contract on the Bursa Malaysia Derivatives Exchange was down 34 ringgit, or 0.72%, at 4,666 ringgit ($1,143.63) a metric ton at the midday break. The FCPO, the crude palm oil futures contract, is tracking weakness from Dalian market as well as Chicago soyoil pricing while waiting for export data, a Kuala Lumpur-based trader said. Dalian's most-active soyoil contract fell 1.66%, while its palm oil contract slipped 2.15%. Soyoil prices on the Chicago Board of Trade were down 0.64%. Palm oil tracks rival edible oils, as it competes for a share of the global vegetable oils market. Oil prices fell more than 1% on Thursday as investors weighed risks to supply from attacks on shipping through the Strait of Hormuz against US efforts to cut petroleum shipping costs by easing sanctions on vessels.
