Wheat supported by weak dollar, Russian export quotas

CHICAGO, March 13 (Reuters) - Chicago Board of Trade

corn and soybean futures turned higher on Thursday, after

private estimates for Argentina's corn and soy crops fell,

analysts said.

Wheat futures also rose after Russia's IKAR cut its wheat

export forecasts, sparking buying interest in U.S. wheat

futures.

However, traders remained cautious given twists and turns in

U.S. President Donald Trump's ongoing tariff war.

"The tariff situation is clouding the situation a little

bit," Mark Soderberg, analyst at ADM Investor Services, said.

The most-active corn contract on the Chicago Board of Trade

settled up 4-1/2 cents to $4.65-1/4 a bushel. CBOT

soybeans settled up 10-1/4 cents at $10.10-3/4 per bushel

and CBOT wheat settled up 8-1/2 cents at $5.62-1/2 a

bushel.

Argentina's Rosario Grains Exchange lowered its outlooks for

the nation's 2024-25 corn and soy harvests on Wednesday, adding

support to U.S. corn and soy futures.

"Those numbers are having an impact," said Jim Gerlach,

president of A/C Trading.

Soybean futures also received a boost from

higher-than-expected weekly U.S. soybean export sales. However,

expectations for a massive soybean harvest in top-supplier

Brazil continue to hang over futures.

Grain markets were unsettled on Wednesday by the

implementation of increased U.S. tariffs on all steel and

aluminum imports, prompting the European Union and Canada to

announce retaliatory duties on a range of U.S. goods.

The EU package, which could see the bloc reintroduce a 25%

duty on U.S. corn and potentially add a tariff on U.S. soybeans,

added to concern about disruption to U.S. exports caused by

President Donald Trump's tariff offensive.
