BEIJING, June 8 (Reuters) - Chicago wheat futures fell on Monday to their lowest level in two months, pressured by abundant global supplies, weak demand for U.S. exports and the advancing harvest in the U.S. Plains.

The most-active wheat contract on the Chicago Board of Trade (CBOT) Wv1 was down 0.47% at $5.77-1/4 a bushel, as of 0157 GMT, extending losses to a seventh consecutive session.

Large Northern Hemisphere crops continued to weigh on the market despite a drought-diminished U.S. winter crop.

In Ukraine, APK-Inform agriculture consultancy said on Sunday it revised up the country's wheat harvest to 21.7 million tons from 19.9 million tons.

Last week, Russia's IKAR consultancy also hiked its forecast for the country's 2026 wheat crop to 91.5 million metric tons from 90 million tons.

Improved moisture in drought-hit U.S. wheat-growing areas added further pressure, while the winter wheat harvest gathered pace, boosting already strong grain supplies.

Soybeans Sv1 slipped 0.09% to $11.20-1/2 a bushel, while corn Cv1 lost 0.18% to $4.16-3/4 a bushel, weighed by favourable weather conditions and the absence of renewed Chinese demand for U.S. crops.

Market participants continue to watch for signs of fresh Chinese demand after Beijing and Washington agreed to expand agricultural trade in mid-May. The lack of significant purchases since then has weighed on soybean prices.

Forecasts for above-normal rainfall across much of the U.S. Midwest over the next two weeks are expected to support germination and crop development for recently planted corn and soybeans, forecasters said late last week.

Higher crude oil prices offered some support to corn and soybean markets, as both crops are used in the production of biofuels.
