Overview
- Emergency negative balance remains $1,200 for buses, subways and fluvial services in November 2025.
- AMBA trains and the Tren del Valle allow up to $650 in negative balance, while the Urquiza line permits $480.
- Trips validate only if the fare fits within the available negative allowance, and the debt is automatically deducted on the next recharge.
- Top-ups max out at $40,000 when accredited via the SUBE app; validations at terminals or on board cap loads at $9,900 due to offline processing limits.
- Remote loads such as Mercado Pago still need accreditation at a terminal or via NFC, and in cities like Rosario the $1,200 cushion no longer covers a single bus fare.
