Argentina grain exports disrupted as maritime pilots strike over deregulation decree

Argentina's grain export system has been disrupted after maritime pilots walked off the job, preventing ships from entering and leaving key ports. The strike has affected more than 45 vessels, according to a business chamber representative, and has slowed commercial activity in one of the world's most important food-export corridors. The disruption is centred on ports along the Parana River, through which most of the country's soy, corn and wheat shipments move.

The walkout began on Monday after the government published a decree on Friday that deregulates river navigation services. The decree was signed by President Javier Milei and says it is intended to streamline procedures, modernise regulatory requirements and remove obsolete or disproportionate rules. Gustavo Idigoras, president of CIARA-CEC, said on social media that at least 45 vessels had been affected and warned that if the dispute was not resolved on Tuesday, about 30 more ships could be added to the backlog.

The strike is being led by pilots who guide ships through Argentina's rivers and coastal waters into its main commercial ports. These workers have specialised knowledge of the waterways, making their role central to the movement of bulk cargoes. A union representing the pilots has warned that the decree could reduce demand for Argentine pilots and put jobs at risk.

Argentina's coastguard responded on Tuesday by ordering the pilots back to work through a notice in the official gazette, warning that disciplinary sanctions could follow. The dispute matters because Argentina is the largest exporter of soya bean products and a major exporter of corn and wheat. Any bottleneck at its ports can quickly affect global food markets, especially when shipments are concentrated through a limited number of river routes.

The standoff also highlights the tension between the government's deregulation agenda and labour concerns in a sector that depends on technical expertise and tightly managed navigation rules. The issue comes at a time when Argentina remains a key player in international agricultural trade. In February 2026, the country ratified the EU-Mercosur deal, a major trade agreement between the European Union and four South American countries.

That pact is designed to remove tariffs on more than 90 percent of trade between the two blocs, underlining the wider importance of Argentina's export infrastructure. The current strike shows how quickly domestic regulatory changes can affect the flow of goods beyond the country's borders. What remains unclear is how long the stoppage will last and whether the government, the pilots and the industry can reach a settlement quickly enough to prevent further congestion.

The immediate focus is on whether the order to return to work will be enforced and whether additional vessels will be caught up in the dispute. The next developments will determine how much of the backlog can be cleared and whether the disruption spreads further through the grain export chain.
