Dec 24 (Reuters) - Export premiums for corn, soybeans and
wheat at the U.S. Gulf Coast were mostly steady on Tuesday in
light trading ahead of the Christmas holiday on Wednesday when
U.S. grain markets will be closed, traders said.
* Nearby Gulf basis offers were scarce for all three
commodities as capacity to load ocean-going vessels was
effectively sold out through January. Some exporters may offer a
spot shipment if there is demand, but the price would be at a
large premium to shipments in February and beyond.
* U.S. corn demand was light to moderate as some Asian
buyers have delayed making near term purchases in hopes of
booking cargoes turned away by China for an unapproved GMO
* South Korean buyers have taken a further 120,000 tonnes of
U.S. corn in deals related to a trade disruption caused by
China's rejection of U.S. corn.
* U.S. soybean export demand was fading seasonally as South
American supplies will be available from February. However, U.S.
suppliers continue to capture some sales due to often-lengthy
delays at South American ports. Brazilian port capacity was
largely sold out already for February and March, traders said.
* The U.S. Department of Agriculture on Tuesday confirmed
private sales of 185,000 tonnes of U.S. soybeans to unknown
destinations and 114,000 tonnes to Egypt.
* Trade sources could not confirm that China has canceled
any of its U.S. soybean purchases yet.
* U.S. wheat premiums were anchored by abundant global
supplies of the grain.
* Most global demand for soft wheat was for near term
shipment and U.S. soft red winter wheat offers were thin through
January due to a lack of available loading capacity. SRW prices
for spring shipments were among the lowest on the world market.
Benchmark SRW wheat futures fell to a 19-month low on
* U.S. markets will be closed on Wednesday for the Christmas
holiday. Chicago Board of Trade futures will resume trading at
8:30 a.m. CST (1430 GMT) on Thursday.
* Weekly USDA export sales data will be released on Friday
morning, delayed by a day due to the holiday.
