CHICAGO, Jan 3 (Reuters) - Chicago Board of Trade soybean futures fell sharply on Friday as a flurry of farmer selling took place in the U.S. and South America, and weekly gains for the U.S. dollar weighed on futures prices, analysts said.
CBOT March soybeans SH25 settled down 20-1/4 cents at $9.91-3/4 per bushel.
The spot January soybean contract SF25, which expires on Jan. 14, ended down 18-1/2 cents at $9.81 a bushel.
CBOT March soymeal SMH25 fell $11.30 to end at $308.60 per short ton while March soyoil BOH25 fell 0.34 cents to settle at 39.93 cents per pound.
For the week, most-active soybeans Sv1 rose 0.20%.
The oilseed was pressured by weekly gains for the U.S. dollar, which dipped for the day. 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 484,700 metric tons, beneath trade expectations for 500,000-1,200,000 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.
