JAKARTA, July 27 (Reuters) - Malaysian palm oil futures

declined for a fourth straight session on Monday to their lowest

in nearly three weeks as traders sold positions after data

showed exports fell this month, and as competing oil markets

weighed on prices.

By the day's close, the benchmark palm oil for October

delivery on the Bursa Malaysia Derivatives Exchange

was down 1.74 percent at 2,140 ringgit ($561.39) a tonne after

hitting 2,139 ringgit, its lowest since July 8, earlier in the

session.

Total traded volume stood at 41,956 lots of 25 tonnes each,

well above the roughly 35,500 lots usually traded daily.

"The market is weak. The export figure is bearish," said a

trader with a foreign commodities brokerage in Kuala Lumpur,

adding that competing markets also fell.

"Every indicator points to the market being weak, and our

palm will continue the movement down."

Export data released by cargo surveyor Intertek Testing

Services (ITS) for July 1-25, showed a nearly 18 percent decline

in shipments of Malaysian palm oil at 1,152,045 tonnes compared

with 1,400,162 tonnes shipped during June 1-25.

Societe Generale de Surveillance, another cargo surveyor,

said exports of Malaysian palm oil products for July 1-25 fell

15.4 percent to 1,178,568 tonnes from 1,393,204 tonnes shipped

during June 1-25.

For palm prices to break the current downtrend, exports need

to pick up, the trader said.

"We need demand from the consuming countries because from

this point onwards, all the way to November, our production will

be rising."

In competing markets, oil prices fell to near four-month

lows on Monday after a steep drop in Chinese stock markets and

on more evidence of a global oil supply glut that has halved

prices over the past year.

The U.S. soyoil contract for August was down 0.82

percent in early Asian trade, while the most active January

soybean oil contract on the Dalian Commodity Exchange

lost 1.86 percent. Dalian RBD palm oil for September delivery

was down 2.12 percent.

Chicago Board of Trade November soybean futures fell

1.1 percent to $9.54-1/4 a bushel, near the session low of $9.50

a bushel - lowest since June 23. Soybeans have dropped for nine

sessions out of 10.
