CHICAGO, July 17 (Reuters) - U.S. corn prices fell 1.7
percent on Wednesday as weather models suggested the coming
weeks could be rainier than previously thought in the grain
belt, easing some fears about heat and dryness.
Soybeans were mixed as the more favorable weather outlook
pressured post-harvest prices while strong processor demand and
thin nearby stocks underpinned the old-crop August contract.
Grains markets are currently highly sensitive to slight
changes in weather patterns as crops are nearing critical stages
of development, particularly corn, which will be pollinating
over the next few weeks.
"We've put in enough of a weather premium to cover the
sogginess in the east and the dryness in the west for the time
being," said Sterling Smith, a futures specialist with
A turn to a wetter weather forecast for the next two weeks
in the U.S. Midwest will help boost corn and soybean growth and
diminish the threat of harm to the pollinating corn crop, an
agricultural meteorologist said on Wednesday.
"The European weather model made a notable shift toward
wetter weather next week in most of the Midwest and a slightly
wetter shift in Missouri and Kansas," said Joel Widenor, a
meteorologist for Commodity Weather Group.
Chicago Board of Trade new-crop December corn fell
8-3/4 cents, or 1.7 percent, to $5.02 per bushel, the contract's
third decline in four sessions.
Stiff competition in export markets added pressure after
news that a South Korean feedmaker purchased Black Sea region
corn for December arrival at a steep discount to U.S. prices.
New-crop November soybeans slipped 2-3/4 cents, or 0.2
percent, to $12.83-1/2 a bushel. Old-crop August soybeans
gained 2-1/4 cents, or 0.2 percent, to $14.77-1/2 a bushel,
rising for a third consecutive day.
Wheat futures were firmer much of the day amid expectations
for improving export demand, but closed lower on spillover
pressure from corn and soy.
Brazilian importers are in the market for more U.S. hard red
winter wheat this week following recent large purchases.
Chinese importers are negotiating deals to buy at least half
a million tonnes of Australian wheat for January-March shipment
to replace some of its weather-damaged domestic crop.
China, the world's top wheat grower, may even eclipse Egypt
as the top importer on the globe this season after adverse
weather damaged up to 20 million tonnes of its milling grade
crop, trade sources said.
After the close, Egypt's state wheat buyer announced a
tender to buy an unspecified amount of wheat on the global
market for shipment in late August.
CBOT September soft red winter wheat futures fell
4-1/2 cents, or 0.7 percent, to a one-week low of $6.65 a bushel
while September hard red winter wheat was a penny lower
at $7.02-3/4 a bushel.
