The fund prices are share prices rather than bushel prices. The Chicago lines are settlement levels from USDA AMS grain bid reports for Friday 18 September.
Those reports do not carry daily changes, so the table leaves them blank rather than guessing. A DTN-powered quote board and Farmbucks showed November soybeans down about 16 cents on Friday, from 1,319.75 cents to about 1,303.75.
03 What moved it
Chinese state buyers have taken roughly a million tonnes of American soybeans this week, according to Reuters. A DTN-powered quote board showed November soybeans down about 16 cents on Friday from a 1,319.75-cent prior close.
It advances a commitment made at the Busan summit. China agreed at the Busan summit to buy 25 million tonnes of American soybeans annually through 2028, according to Reuters.
A meeting between the American and Chinese presidents is planned for later in September. The buying has run ahead of that meeting.
The funds fell on Friday. Wheat fell 1.45%, the largest loss of the three, and corn fell 0.66%.
04 The Latin American read
Brazil and Argentina compete with American soybeans for Chinese demand. China’s roughly one million tonnes of American purchases this week, reported by Reuters, matter for South American exporters.
The real ended the week at 5.1445 per dollar, a move of 0.46%. A weaker real raises Brazilian growers’ revenue in reais.
Adecoagro, which grows crops in Argentina and Brazil, fell 3.13% to US$11.46 on Friday. It lost 2.63% over the week.
The Mexican peso weakened 1.46% over the week to 17.221 per dollar. The Colombian peso weakened 2.10% to 3,166.69 per dollar and the Chilean peso 1.75% to 958.97.
05 The names to watch

ADM fell 3.30% to US$85.18. The two processors and the South American grower name moved together on the day.
The soybean fund remains above its fifty-day and two-hundred-day moving averages. That longer trend has survived a week in which the fund still finished higher.
The corn fund sits above its fifty-day and two-hundred-day averages as well. Both grain funds have held those levels through a softer Friday.
The Colombian and Chilean pesos were the two regional currencies with the largest weekly moves, at 2.10% and 1.75%. The real moved 0.46% and the Mexican peso 1.46%, behind the Colombian and Chilean pesos.
