Overview
- Resolution 27/2026 took effect Monday, lifting the minimum metropolitan train fare to $310 for registered SUBE users and raising the national‑jurisdiction bus minimum to $714 in the Buenos Aires metro area.
- The plan locks in more steps, with buses set for two additional 2% updates on June 15 and July 15, and trains scheduled to move to $350 in June, $380 in July, $420 in August and $450 in September.
- Fares remain differentiated to push SUBE registration, with non‑registered riders paying double the posted price, the Tarifa Social discount holding at $321.30 for the bus minimum, and a flat $1,100 cash fare applying on trains for any distance.
- The new prices are already changing daily costs on key corridors such as La Plata–CABA, where reported third‑section Roca tickets rise from about $528 now to $848 in September, and La Plata express bus trips climb to around $4,803 after the 2% increase.
- Transport operators say the approved rises lag operating costs and some have pursued legal action over subsidy distribution, raising concerns about strained finances and service frequency on affected lines.
