Chicago | Reuters—Chicago Board of Trade soybean futures ended lower on Tuesday for a third straight session, coming under pressure from hefty South American supplies hitting the global market and uncertainty over how U.S. tariffs will affect domestic demand, traders said.

Corn fell during a choppy trading session, after the federal government left domestic corn inventories unchanged in a monthly supply-and-demand report – despite strong export sales and trade tensions with top buyer Mexico.

Wheat futures ended lower after the U.S. Department of Agriculture reported domestic and global wheat inventories were bigger than trade expectations.

Alberta crop conditions improve: report

Varied precipitation and warm temperatures were generally beneficial for crop development across Alberta during the week ended July 8, according to the latest provincial crop report released July 11.

The CBOT’s most-active wheat Wv1 closed down 5-3/4 cents at $5.56-3/4 a bushel. Corn Cv1 ended down 1-3/4 cents at $4.70-1/4 a bushel, while soybeans Sv1 settled down 2-3/4 cents at $10.11-1/4 per bushel.

Weakness in the canola market RSK5 weighed on soyoil prices, which also carried over to pressure soybean futures, traders said.

Traders and farmers are keeping a close eye on exports, with U.S. tariff disputes with major buyers Mexico, Canada and China threatening sales of U.S. agricultural goods. They said USDA likely held off on changes as it waits to see whether the U.S. implements fresh tariffs and how trading partners respond.

Fears that U.S. tariffs will hurt economic growth have unsettled financial markets, while grain investors are wary that China may shun U.S. soybeans altogether in favor of a bumper Brazilian crop.

With the tariff war roiling between the U.S. and China, “the question is, where are we going to sell the (U.S.) beans? No one knows,” said Jack Scoville, vice president at Price Futures Group in Chicago.

For corn futures, some analysts were baffled why USDA kept the U.S. corn export forecast unchanged, given the current pace of sales.

“I get the whole conversation about trade and tariffs and the unknown,” said Angie Setzer, partner at Consus Ag. “But if all you can do is predict the futures based on normal market trends, as they have told me they do, I’m not sure how they can rationalize not making an adjustment at this point.”
