Chicago Board of Trade soyabean futures closed lower on Thursday, erasing early gains and turning down as a slide in corn and wheat futures outweighed supportive data in a monthly US government crop report, traders said.

CBOT November soyabeans settled down 1/4 cent at $9.23-1/2 per bushel, turning lower after reaching $9.34, its highest since July 15. CBOT December soyameal ended down $1.90 at $307.80 per short ton, while December soyaoil rose 0.07 cent at 29.78 cents per pound.

CBOT soya futures climbed to session highs after the US Department of Agriculture (USDA) in its monthly supply-demand reports cut its estimate of the US average soyabean yield to 46.9 bushels per acre, below an average of analyst expectations and down from 47.9 last month.
