Wheat, corn, and rapeseed prices have surged due to concerns about the upcoming harvest in the Northern Hemisphere, with excessively wet conditions in north-west Europe and worries about regional wheat growing conditions in the US. The European Union's MARS yield assessment has indicated negative impact on yield potential and difficult planting conditions, particularly in Ireland and the UK. In the US, grain prices have reached their highest level for wheat since early March, with the USDA announcing that the condition of winter wheat has worsened.
