WHEAT - Down 5 to 6 cents

• CBOT wheat eased on an accelerating winter wheat harvest in the U.S. and forecasts for the Russian wheat harvest becoming more optimistic.

• Argus Media has increased its forecast for Russia's 2025/26 wheat production by 4.5 million metric tons since March, projecting output to reach 84.8 million tons, now significantly higher than last year's harvest of 81.3 million tons.

• Egypt has imported 4.9 million metric tons of wheat so far this year, the agriculture ministry said on Monday.

CORN - Down 4 to 7 cents

• CBOT July corn CN25 last down 6-1/4 cents at $4.22-1/2 per bushel.

SOYBEANS - Down 4 to 6 cents

• CBOT soybeans Sv1 reversed gains after soyoil prices followed crude oil higher on fears that U.S. strikes on Iranian nuclear facilities could lead to supply disruption.
