Corn futures fell nearly 6 percent in U.S. trading as the dollar index rose. Fed Chair Janet Yellen was giving semiannual testimony to Congress, and British voters were set to decide on EU membership the following Thursday.
The dollar's gain was cited as the main pressure on corn.
A stronger dollar makes U.S. corn less competitive in export markets, which lowers prices. Macro uncertainty around monetary policy and the Brexit vote adds volatility to grain markets.
After 301 past bearish macro events, Corn moved a median -0.1% over 5 sessions (47% higher; middle half -2.2% to +1.3%), and +0.2% over 20.
After 2,356 past bullish macro events, US Dollar (Broad) moved a median +0.2% over 5 sessions (60% higher; middle half -0.3% to +0.7%), and +0.4% over 20.
