Falls on relief Russian and Ukrainian grain port attacks not intensive

Soybeans, corn rise on concerns about dry U.S. weather

Recasts with wheat's fall in European trade, adds new comment, changes dateline

- Chicago wheat hit new two-year highs on Monday as disruptions to Black Sea shipments were feared after Russian and Ukrainian attacks on grain ports and ships continued, but then slipped as the attacks did not seem so intense as last week.

Soybeans and corn rose on concerns about dry weather in the U.S. and Chinese demand for U.S. beans.

Chicago Board of Trade most-active wheat Wv1 fell 0.5% to $6.78-3/4 a bushel at 1134 GMT, after earlier hitting $6.87-1/2, the highest since June 2024 and above a previous two-year high on Friday.

Soybeans Sv1 rose 1.2% to $12.17-3/4 a bushel, corn Cv1 rose 1.2% to $4.73-1/4 a bushel.

Wheat prices rose in the past week after attacks on grain ships and ports in the Black Sea and the Sea of Azov by Ukraine and Russia. A Russian missile strike on a ship carrying corn near Ukraine's Odesa port killed 10 people, Ukrainian officials said on Monday.

“Wheat is overall supported by the attacks on ports and shipping by Ukraine and Russia,” said Matt Ammermann, commodity risk manager at StoneX. “But rises are limited as the grain terminals and ships do not seem to be taking such heavy strikes as last week with Ukraine concentrating more on attacking tankers.”

“There is also relief that Ukraine has not attacked the huge grain terminals in the huge Russian wheat export port of Novorossiysk, such attacks could have an enormous impact on wheat markets.”

Soybeans were underpinned by rising crude oil and sales of U.S. soybeans to China.

“Corn and soybeans are supported by concern about dry weather forecast this week in U.S. grain belts which could potentially be negative for crop yields," Ammermann said.

Two large purchase tenders issued by Korean buyers also underpinned corn. GRA/TEND
