President Javier Milei signed a decree deregulating river navigation services, according to Al Jazeera and Buenos Aires Herald. Maritime pilots subsequently struck at ports including Rosario, Bahía Blanca, and Quequén, with operations rerouted to Montevideo and southern Brazil at reported added costs of US$700–1,000 per container. Vessel counts affected remain disputed between the two sources, while the Argentine Energy Chamber reported 12 tankers stalled.
