An industry advocacy piece reports that 80 percent of commercial locks saw an unexpected outage in 2016, up from 71 percent in 1993. Most locks were built more than fifty years ago and have had few upgrades, and a major barge operator says stalled barges can hold commodities for extended periods.
Frequent lock outages lengthen barge transit times and raise costs, which can narrow river basis for grain and soybeans. The impact is ongoing rather than a sudden price shock.
Not enough comparable past events yet for a historical read.
After 1,054 past logistics events, Corn moved a median -0.1% over 5 sessions (48% higher; middle half -1.5% to +1.5%), and -0.0% over 20.
After 837 past logistics events, Soybeans moved a median +0.4% over 5 sessions (55% higher; middle half -1.5% to +2.0%), and +0.6% over 20.
Moves of each commodity's benchmark from the last close before the event. Historical reads pool past events of the same kind; they describe what happened, not what will. Not investment advice.
