Soybean futures rose on Wednesday, a day of short-covering prompted by worries about the hot and dry weather that could threaten soybean seeding in Brazil, a top producer.

Corn prices fell slightly in early U.S. harvest as the industry remained cautious about making big decisions.

Wheat prices fluctuated as traders weighed the diminished yields of wheat in the European Union versus a strong export flow from Black Sea.

The Chicago Board of Trade's (CBOT), most active wheat contract, remained unchanged at $5.75-3/4 a bushel. CBOT corn rose 1/4 cent to $4.12-3/4 a bushel and soybeans gained 8 cents to $11.14 a bushel.

Maxar's analyst note said that a delayed rainy season has resulted in depleted moisture in large areas of Brazil, including Mato Grosso. This is one of Brazil’s most important soybean-growing states.

Conab, the Brazilian statistics agency, still projected Tuesday that the country's soybean crop for 2024/25 would be 166.28 millions metric tons. This is an increase of 12.8% over the previous season.

The lack of rain won't be alarming until the drought extends into October. This could delay the planting of soybeans.

In the United States traders are closely watching the rapid progress of the soy and corn crops, which will produce bumper yields.

Brian Basting, an analyst at Advance Trading, stated that they were in a waiting-and-seeing mode.

Chicago corn and soy futures are under pressure due to high yield expectations, but rains expected this weekend could hamper harvesting in certain areas.

The large exports of Black Sea wheat, which is cheap and plentiful, continued to put pressure on the wheat price despite damage caused by dry weather in some Black Sea crops as well as a lower forecast for French soft-wheat exports.
