GRAINS-Chicago corn and soybeans stuck at multi-month lows as weather weighs

PARIS/BEIJING, June 26 (Reuters) - Chicago corn and soybean futures hovered around multi-month lows on Thursday as favourable U.S. weather and expectations of record Brazilian crops maintained supply pressure.

Wheat fell for a fourth day as an advancing U.S. harvest and rising expectations for Russian production also kept the focus on ample global supply.

The most active corn contract Cv1 on the Chicago Board of Trade was unchanged on the day at $4.05 a bushel at 1233 GMT. It earlier fell to its lowest since October at $4.02-1/4, in the latest of a series of 2025 lows.

CBOT soybeans Sv1 were up 0.15% at $10.20 per bushel after earlier reaching their lowest since April 10 at $10.16. CBOT wheat Wv1 eased 0.55% to $5.41-1/2 a bushel.

"Warm, rainy weather in the U.S. Midwest (is) expected to aid crop development for the recently planted corn and soy crops," Saxo Bank said in a note, adding that wheat was facing "a strong production outlook across the Northern Hemisphere, where harvesting is under way."

Brazilian farmers will produce a record 123.3 million metric tons in the second corn crop, agribusiness consultancy Agroconsult forecast on Tuesday after surveying fields in key producing regions nationwide. The country is already estimated to have harvested a record soybean crop earlier this year.

One concern for the corn market was hot weather in Europe, including in France, in the run-up to the crucial pollination period for corn in July.

In wheat, consultancy IKAR said on Thursday it had raised its 2025 Russian wheat production forecast to 84.5 million metric tons from 83.8 million, joining other analysts in raising their outlook for the upcoming crop.

Grain markets are also turning their attention towards the U.S. Department of Agriculture's crop progress and quarterly stocks reports due Monday.
