CHICAGO, May 24 (Reuters) - Nearby U.S. soybean futures fell
on Friday for the first time in seven sessions and spot corn
futures eased after two days of gains as investors squared
positions ahead of the three-day U.S. Memorial Day holiday
Deferred contracts of both commodities posted modest gains
in thin trading volume.
Wheat prices declined on profit-taking following a 2 percent
surge a day earlier and on forecasts for rain in the southern
Plains wheat belt this weekend that could boost yields slightly
in the nearly mature crop.
Volatile price moves on Thursday left some traders weary so
trading volume was light. Chicago Board of Trade futures markets
will be closed on Monday.
"We have a three-day weekend in front of us and there's a
bit of fatigue after Thursday's price action, the big rejection
of prices on soybeans. That might have shocked a few traders and
moved them to the sidelines today," said Rich Nelson, chief
strategist with Allendale Inc.
He was referring to an uncommonly wide trading range of
nearly 60 cents a day earlier and a steep late-session spike
followed by a rapid retreat. The whipsaw price moves also
spilled over to corn and wheat.
CBOT July soybeans fell 23-1/4 cents, or 1.6 percent,
to $14.76-1/4 per bushel. The contract encountered chart
resistance near $15.00 and selling pressure intensified as
prices fell below Thursday's low of $14.87-1/2 and below chart
support around $14.80.
"There are a lot of ideas that we peaked out yesterday and
we're seeing some follow-through selling here today. It doesn't
help that basis levels have backed off. Apparently a lot of cash
beans moved on Thursday's rally," said Jack Scoville, vice
president for Price Futures Group.
"It's a thin trade today so it doesn't take a whole lot to
move the market," he added.
Persistent rumors that top soybean importer China was
cancelling some of its Brazilian soybean purchases and that U.S.
livestock and poultry producers were importing more South
American cargoes added to the bearish tone, traders said.
Still, soybeans posted a fourth straight weekly advance,
adding 1.9 percent in the week.
Old-crop corn prices slid lower on light profit taking.
Deferred contracts edged higher in light trade, with gains
capped by forecasts for scattered rain around the U.S. Midwest
that were expected to boost the recently planted crop.
More than 70 percent of the crop was seeded as of last week
and some analysts believe planting could reach 80 to 85 percent
by this weekend.
CBOT July corn dipped 4-3/4 cents, or 0.7 percent, to
$6.57-1/4 a bushel but ended the week higher for a second
consecutive week, adding 0.7 percent.
Trading was thin ahead of the three-day holiday weekend,
with corn volume totaling little more than half of its 250-day
Wheat retreated from Thursday's one-week high, although
declines were limited by a sign wheat export demand may be
The U.S. Agriculture Department on Friday confirmed private
sales of 180,000 tonnes of new-crop soft red winter wheat to
CBOT July wheat shed 5-3/4 cents, or 0.8 percent, to
$6.97-1/2 a bushel but closed with a 2.1 percent weekly gain,
its first in three weeks.
Commodity funds were net sellers of an estimated 2,000 wheat
contracts on the day, as well as 3,000 corn contracts and 7,000
soybean contracts, trade sources said.
