Wheat and corn prices on Euronext saw an increase, reaching their highest level in nearly two months due to the loss of competitiveness of Russian wheat, depletion of national stocks, and a proposed limited export quota. The market's firmness is also attributed to the anticipation of a reduced Russian harvest next year. However, the market's tension is being eased by positive revisions in harvests in Argentina and Australia. Similarly, corn prices recovered from two sessions of losses, supported by the recovery in Chicago's market, despite some setbacks in the US market.
