Chicago soybean futures slid for a third consecutive session on Monday to their lowest in more than nine months as higher U.S. stocks weighed on the market. The most-active soybean contract on the Chicago Board of Trade (CBOT) Sv1 lost 0.4% to $12.41-1/2 a bushel after dropping earlier in the session to $12.40 a bushel, the lowest since late December.  Soybean futures fell on pressure from larger-than-expected stocks reported on Thursday by the U.S. Department of Agriculture (USDA). There was additional pressure stemming from the ongoing U.S. harvest. The USDA reported Sept. 1 soybean stocks at 256 million bushels, above the entire range of trade estimates in the Reuters pre-report poll. After Friday's CBOT close, the USDA said U.S. processors crushed 168.2 million bushels of soybeans in August, below an average of trade estimates for 169.0 million. The Commodity Futures Trading Commission's weekly commitments of traders report also showed that noncommercial traders, a category that includes hedge funds, increased their net-short position in CBOT wheat and raised their net-long position in soybeans.
