Chicago Board of Trade corn futures settled mostly higher on Monday on supportive weekly US corn export inspections, slipover support from gains in neighbouring soyabeans, and US weather worries, brokers said.
CBOT corn futures ended up 1-1/4 cents to down 1/2 cent per bushel, with September up 1-1/4 cents at $2.27 and December up 1-1/4 cents at $2.38. Commodity funds ended the session nearly even, brokers said.
Man Financial sold about 1,500 December, while commercials were net sellers, with Term Commodities selling 1,500 December. Man Financial also bought 2,000 December $2.10 put options, brokers said.
Weekend US corn export sales business was quiet, but light support stemmed from better-than-expected US weekly corn export inspections data, brokers noted.
The US Department of Agriculture reported on Monday that weekly US corn export inspections for the week ended August 5 totalled 36.275 million bushels, above traders' estimates for 30 million to 33 million bushels.
Cooler-than-desired temperatures across the US Midwest were also causing some concerns about "finishing" the corn crop, a supportive factor for CBOT corn, CBOT brokers noted.
But many CBOT traders said the cool temperatures were more of a problem for later-planted US soyabeans, which are in their key pod-setting and pod-filling stage of development.
The US corn crop has already gone through its key pollination stage of development, they noted.
After the CBOT close, the USDA reported the US corn crop's condition had stabilised, with 76 percent in good to excellent condition, equal to last week's rating. Forty-two percent of the crop was douching while 14 percent was dented, the USDA said.
Light support also stemmed from gains in CBOT soyabeans, which settled on Monday up 6-3/4 cents to 10 cents per bushel on worries about the cooler US forecasts, brokers said.
US Midwest cash corn basis bids were firm late on Monday, while Gulf CIF basis bids weakened, dealers said.
