Chicago Board of Trade soyabean futures were weak at midday Thursday as commercial sales and harvest pressure offset supportive weekly US soyabean export sales and buying on technically oversold signs, brokers said.
Soyabean futures were down 1-1/4 cents to unchanged, with November down 1/2 cent at $5.66 and January down 1-1/4 cents at $5.73.
ADM Investor Services bought 800 November early, Cargill sold 600 November and Produce Grain spread November/January, brokers said.
Besides the light commercial sales, ongoing reports of excellent US harvest yields, mostly above 50 bushels per acre, weighed on the market at midday, brokers said.
That figure tops the government's latest monthly estimate of an average soya yield of 38.5 bushels per acre. Early buying had followed supportive weekly export sales news, brokers said.
The US Department of Agriculture reported soyabean export sales during the week ended September 9 totalled 634,900 tonnes, above traders' estimates for 350,000 to 500,000 tonnes.
There were no deliveries posted Thursday against the expired September soyabean and soya product futures contracts.
Soyameal futures were up 50 cents per ton to down 10 cents, with October up 30 cents at $165.50 and December down 20 cents at $167 per ton. Fimat Futures bought 200 December and Iowa Grain bought 200 January, brokers said.
Supportive weekly soyameal export sales data offset pressure from weak US cash soyameal basis offers, brokers said.
