Overview

• From 1 September, CABA bus minimum fares rose to $526.13 and provincial lines to $529.25 under the monthly indexation formula.
• Buenos Aires subte fares increased about 3.87%, with 1–20 monthly trips priced at $1,071 for registered SUBE users as published by SBASE in the Boletín Oficial.
• National‑jurisdiction bus lines in the AMBA and commuter trains did not change fares, leaving the national bus minimum at $451.01 and enlarging the price divergence.
• Riders using unregistered SUBE cards pay substantially more—reported up to roughly 60% higher—due to the loss of the automatic subsidy.
• Cumulative 2025 increases reach about 41–42% for urban transport, and City tolls also rose in September, with peak charges such as $4,354.78 on Perito Moreno and 25 de Mayo partly supporting subte funding.
