Euronext wheat prices increased on Monday due to concerns over weather risks to the Northern Hemisphere planting season and lower-than-expected U.S. corn and soybean stocks. However, gains were limited by higher-than-expected U.S. wheat stocks. Adverse weather conditions, such as drought in Russia and heavy rains in the EU, and potential supply shortages have led to high premiums for late-delivery positions on Euronext. Additionally, prices in Poland have risen due to tight export supplies and reluctance to sell at current low levels.
