Investing.com - U.S. wheat futures extended sharp losses from the previous session on Thursday, as investors bet that demand for U.S. supplies will weaken after prices rose to a six-month high earlier in the week.
On the Chicago Mercantile Exchange, US wheat for March delivery tumbled 8.65 cents, or 1.47%, to trade at $5.8075 a bushel during U.S. morning hours.
A day earlier, US wheat futures plunged 13.6 cents, or 2.28%, to settle at $5.8940 a bushel.
Prices of the grain hit $6.1160 on December 2, the most since June 10, amid speculation Russia will limit its exports of the grain in the current marketing season.
Russia, the world's third-largest wheat exporter, has shipped approximately 14 million tons of wheat so far in the 2014-15 marketing season, which started on July 1.
Meanwhile, soybean and corn futures were lower after agricultural meteorologists predicted mostly favorable weather across key grain-growing regions in Brazil, boosting optimism over crop prospects.
US soybeans for January delivery declined 2.37 cents, or 0.24%, to trade at $9.9563 a bushel, while US corn for March delivery shed 0.62 cents, or 0.16%, to trade at $3.8138 a bushel.
Corn is the biggest U.S. crop, followed by soybeans, government figures show. Wheat was fourth, behind hay.
