CHICAGO, June 28 (Reuters) - U.S. futures for corn to be
harvested this autumn plunged more than 4 percent on Friday,
hitting the lowest point in a year, after the U.S. Department of
Agriculture said farmers have planted 2 million more acres of
the crop than expected.
Favorable crop weather around the Midwest reassured
investors that the fall harvest could be the largest ever,
boosting U.S. stocks to 2 billion bushels by the end of next
season and replenishing 16-year low stocks this summer.
Soybean futures for autumn-delivered supplies slid more than
1 percent on good crop weather and on spillover pressure from
sinking corn, shrugging off a USDA plantings estimate that was
200 million acres below trade expectations.
Wheat futures on the Chicago Board of Trade (CBOT) slipped
to a one-year low on harvest pressure, falling for a seventh
straight session in the longest losing streak for the spot
contract in 3-1/2 years.
"The corn number coming in higher than March intentions is a
shocker here. Two million acres above expectations is considered
bearish," said Joe Vaclavik, president of Standard Grain.
"We were a bit lighter on acreage in beans, and stocks came
in a little below expectations," he said.
Based on a survey of 70,000 farmers, the USDA pegged corn
plantings at 97.379 million acres, 2 million acres, or 2
percent, more than expected by analysts.
Soybean plantings were a record 77.728 million acres, up 1
percent from last year, but 200,000 acres lower than the average
Nearly ideal corn and soybean growing weather is expected in
early July in the U.S. Midwest, with moderate temperatures and
occasional showers likely, an agricultural meteorologist said on
"It looks real good for the next two weeks, there will be
regular showers and cooler temperatures in all areas," said Andy
Karst, meteorologist for World Weather Inc.
Tighter-than-anticipated old-crop stocks of corn and
soybeans underpinned nearby contracts of both commodities,
though gains were restrained by deferred-month declines.
"Old-crop corn stocks and old-crop bean stocks are still
going to remain razor tight. But the new crop production
potential and the good weather trumps the stocks," said Don
Roose, president of U.S. Commodities.
USDA pegged the June 1 U.S. corn stockpile at 2.764 billion
bushels, below the average trade view of 2.845 billion, and
soybean stocks at 718.3 million bushels, below the
745-million-bushel trade outlook.
