- First reported
- 2026-08-04 (4 August 2026)
- Severity basis: Press reported that Argentina's main ports, including the Greater Rosario hub, stopped for about four days because ships could not move without pilots, which is a simultaneous stoppage of the principal ports of one country.
What happened
Starting on 2026-08-01 (1 August 2026), most river and harbour pilots in Argentina stopped accepting new assignments after a presidential decree, published on 31 July, reformed the rules for pilotage. Large vessels cannot move safely on the Parana waterway without a pilot, so ships could not enter or leave ports. Press counts of waiting vessels ranged from about 140 to more than 150, with grain and fuel shipments held up at the Greater Rosario hub. The coast guard ordered pilots back to work and warned of sanctions. On 2026-08-04 the government and the pilots agreed to suspend the decree, cut pilotage tariffs by 20 percent and open a joint working group. Decree 716/2026, published on 2026-08-06, formalised the suspension.

Timeline
- Decree 690/2026 is published. It replaces the 1991 pilotage rules, opens the pilot register without a numerical cap, sets maximum tariffs and lets some foreign captains sail without a local pilot. [s1]
- Pilots and river guides begin refusing new assignments and honour only services contracted before the stoppage. Ships start to queue unable to enter or leave ports. [s1] [s2]
- Press puts the number of stranded ships at 140 to more than 150. The government and the pilots agree to suspend the decree, cut tariffs by 20 percent and form a working group, and pilots resume work. [s1] [s2] [s3]
