Dec 12 (Reuters) - Basis bids for soybeans shipped by barge
to the U.S. Gulf Coast were mostly steady early on Thursday,
underpinned by moderate exporter demand and slow movement of
supplies through the shipping pipeline, traders said.
* CIF corn basis bids were narrowly mixed and wheat basis
bids were steady to firm.
* Spot barge freight rates were about unchanged amid slow
grain loading and slowed river navigation due to frigid weather
around the Midwest. Ice forming around barges slowed movement
through locks in northern areas, traders said.
* Temperatures fell to zero degrees Fahrenheit (minus 17.8
Celsius) or a few degrees below on Thursday in much of the
central Midwest, with colder readings in the north, forecasters
* Spot barges loaded in St. Louis and south, including the
Ohio River, were at a 1 cent-per-bushel premium to bids with no
loading location specifics because of concerns about ice
building slowing deliveries, a trader said.
* Bids for soybeans delivered by rail to the Gulf of Mexico
have also increased about 3 to 4 cents per bushel this week as
exporters turned to other transportation methods to transfer
supplies to export elevators amid concerns about river ice.
* CIF basis bids for soybean barges loaded in the first half
of December were 104 cents over Chicago Board of Trade January
futures and last-half December loadings were bid 100 over,
both about steady.
* CIF basis bids for corn barges loaded in the first half of
December were down a penny at 70 cents per bushel over CBOT
March futures while last-half December bids gained a penny
to 74 over.
* CIF basis bids for December soft red winter wheat barges
were 5 cents higher at 100 cents over CBOT March futures.
