The expansion of the Panama Canal will allow larger ships to pass through the canal. This will impact global trade routes and patterns. The United States expanded the Panama Canal to keep it competitive and allow more cargo to pass through. The expansion includes new locks that can accommodate larger post-Panamax ships carrying up to 12,500 containers. This is expected to double the amount of goods passing through the canal. It may increase cargo volumes at Gulf ports in the United States and lead to more feeder ship traffic from Caribbean transshipment hubs. However, shippers will continue to make routing decisions based on fuel costs, delivery times, and the capabilities of ports along different trade routes.
