Maritime pilots walked off the job on Aug. 3 to protest a Milei decree that deregulated river navigation services, halting ship entry and exit at Argentina's grain ports.
At least 45 vessels were affected by the strike, according to the CIARA-CEC business chamber. Argentina is the world's largest exporter of soybean meal and oil and a major supplier of corn and wheat.
A port bottleneck on the Parana River restricts Argentine export supply of soymeal, soyoil and corn and lifts prices for these products. The size of the disruption and the number of affected vessels make it a meaningful driver.
After 285 past bullish logistics events, Corn moved a median +0.1% over 5 sessions (52% higher; middle half -1.5% to +1.5%), and +0.8% over 20.
After 167 past bullish logistics events, Soybean Meal moved a median +0.5% over 5 sessions (54% higher; middle half -1.8% to +2.9%), and -1.2% over 20.
After 85 past bullish logistics events, Soybean Oil moved a median +0.7% over 5 sessions (64% higher; middle half -1.3% to +2.7%), and +3.1% over 20.
