Chicago | Reuters — U.S. corn futures extended gains into a fourth session on Friday and posted the first weekly rise in a month as slow farmer sales of newly harvested grain and reports of lower-than-expected harvest yields supported the market.

Soybeans rose as domestic demand remained brisk and as trade negotiations between the U.S. and top soy buyer China appeared to be back on track following moves by both sides that escalated trade tensions last week.

Wheat firmed and managed its first weekly advance in five weeks, supported by short covering and bargain buying following the market’s recent drop to five-year lows.

U.S. grains: Corn, soybeans higher in technical bounce; wheat firms

Chicago | Reuters – Chicago corn futures rose modestly on Thursday on chart-based buying, firm cash markets and reminders of…

Trading remained cautious as the U.S. government shutdown deprived the market of key data including corn and soybean harvesting progress and updated yield estimates.

U.S. farmers are widely expected to reap a record corn crop and a bumper soy crop, but reports of crop shortfalls in spots have cast doubt about the government’s most recent estimates.

Sluggish farmer sales of newly harvested corn and soybeans also underpinned futures.

“For corn at these price levels, many people are underwater. They can’t afford to sell it because they’d have a loss,” said Don Roose, president of U.S. Commodities. “The farmer’s not selling soybeans either.”

Soybeans were also lifted by strong demand from U.S. processors and historically high crush rates have eased some concerns about a lack of demand for exports to China.

Global grain merchant ADM is offering incentives for U.S. farmers to deliver soybeans to a major processing facility this month, sources said.

Chicago Board of Trade December corn CZ25 settled up 3/4 cent at $4.22-1/2 a bushel for a 2.3 per cent weekly gain. November soybeans SX25 rose 8-3/4 cents to $10.19-1/2 a bushel, rising 1.3 per cent in the week. CBOT December wheat WZ25 added 1-1/4 cents to end at $5.03-3/4 a bushel, up 1.1% in the week.
