UOCRA construction workers began blockades at San Lorenzo port terminals on July 7 at 06:00, stopping cargo discharge and personnel access at several upriver terminals. Vicentin, ADM Agro and ACA San Lorenzo terminals were reported unaffected.
The action was for an undetermined period and provincial authorities had not yet intervened.
Blockades at multiple Rosario-area terminals delay grain and meal exports and can slow crushing plant throughput. The duration of the action determines whether the effect on soymeal and corn export flows becomes material.
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 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.
