CBOT soybeans tumble as hopes for Chinese demand wane

CHICAGO, Sept 22 (Reuters) - Chicago Board of Trade soybean futures fell to a six-week low on Monday, as a phone call last week between U.S. President Donald Trump and Chinese President Xi Jinping provided no signs of progress on negotiations over agricultural exports, analysts said.

• CBOT November soybeans SX25 settled 14-1/2 cents lower to $10.11 per bushel.

• CBOT December soymeal SMZ25 ended $3.90 lower to $280.10 per short ton and December soyoil BOZ25 fell 0.93 cent to settle at 49.69 cents per pound.

• China, by far the world's largest soy importer, has yet to book any of the current U.S. soybean crop and has instead turned to South American supplies.

• News that Argentina will remove export taxes on all grains until October 31 has pressured Chicago corn and soy futures, as the measure will boost the competitiveness of Argentina's corn and soy exports.

• Soybean futures were also pressured by the expanding U.S. harvest.

• Brazil's soybean planting for the 2025/26 season reached 0.9% of the total expected area as of last Thursday, agribusiness consultancy AgRural said on Monday, adding that intensified work in the fields was registered in the states of Parana, Mato Grosso, Rondonia and Sao Paulo.
