The EU's MARS crop monitoring service cut its cereal yield forecasts for the period through 10 September, with the all-cereal average about 1% lower than last month. Corn yields were cut sharply, mainly in Germany and France, while wheat was forecast 1.9% above the five-year average.
Spain was hit hard by dryness, and Poland also did worse.
Lower EU corn yields tighten feed grain supply and support corn prices, while the wheat outlook stays comfortable. Spain's losses also reduce the EU's barley and wheat exportable surplus.
After 1,465 past bullish weather events, Corn moved a median +0.2% over 5 sessions (54% higher; middle half -1.4% to +1.9%), and +0.9% over 20.
After 224 past neutral weather events, Wheat (SRW) moved a median -0.1% over 5 sessions (46% higher; middle half -1.4% to +1.5%), and +0.4% over 20.
