CHICAGO, Jan 3 (Reuters) - Chicago Board of Trade corn futures fell on Friday as a flurry of farmer sales took place in the U.S. and South America, according to analysts, and the U.S. dollar headed for weekly gains.
CBOT March corn CH25 settled down 8-3/4 cents at $4.50-3/4 per bushel.
For the week, most-active corn Cv1 declined by 0.72%.
Corn was pressured by weekly gains for the U.S. dollar, even though the currency dipped for the day, analysts said. A strong dollar tends to make U.S. exports more expensive and less attractive to holders of other currencies.
The U.S. Department of Agriculture reported weekly export sales for the week ended Dec. 26 at 777,000 metric tons, beneath trade expectations for 800,000-1,400,000 metric tons, according to a Reuters poll of analysts.
A hot, dry austral summer is beginning to cause damage to Argentina's 2024/25 soybean and corn crops, the country's two main grains exchanges said on Friday.
