Weather concerns are back on the radar and are affecting new-crop grain prices. Global grain prices kicked on again this week, especially new-crop, based on weather concerns around winter and spring planted crops. MATIF December wheat gained €6/t last week to finish on Friday 16 April at €206/t and closed on the following Tuesday at €210/t. Similar increases happened in the US, where wheat price in Chicago for December went above the highest it has been this year so far. The hike in wheat prices there was largely driven by concerns over cold damage to winter crops that are now at stem extension, but there is also concern expressed over planting its spring wheat crop.
