Unusually cold weather in Russia from May 11 to 20 ran 3 to 5 degrees Celsius below the 30-year average in central and southern regions. Wheat and barley ripening has been delayed, pushing back the harvest start by about 10 to 12 days for wheat and 5 to 6 days for barley.
A later Black Sea harvest reduces near-term supply of cheaper new-crop wheat and barley and may make Saudi barley shipments harder to source from the region. This supports nearby wheat and barley prices.
After 1,072 past bullish weather events, WHEAT moved a median +0.2% over 5 sessions (55% higher; middle half -1.4% to +2.3%), and +0.3% over 20.
