USDA Economic Research Service published a report on drought-tolerant corn, noting that GE and non-GE drought-tolerant varieties became widely available between 2011 and 2013. By 2016, 22 percent of US corn acreage was planted to drought-tolerant varieties, concentrated in drought-prone regions.
Wider adoption of drought-tolerant hybrids moderates yield volatility in dry years, a slightly bearish structural factor for corn risk premium, though the effect is gradual.
After 770 past neutral report events, Corn moved a median +0.2% over 5 sessions (54% higher; middle half -1.1% to +1.6%), and +0.7% over 20.
