Overview

• The Banco Central’s ICL rose 66.11% from July 2024 to July 2025 for contracts signed before January 1, 2024, and this annual adjustment remains in effect through December 2025.
• Javier Milei’s December 2023 decree scrapped Law 27.551’s mandatory annual ICL updates, allowing landlords and tenants to freely negotiate indexation formulas for new leases.
• Most post-January 2024 contracts now reference the INDEC’s IPC with quarterly or semestral adjustment clauses that translate to around 3.5%–5% monthly rent increases.
• Online inflation calculators from Chequeado and similar tools have become standard resources, while some parties still use manual multiplication of monthly inflation rates to compute updated rents.
• Under a typical quarterly indexation scenario, a rent of $622,309 signed in April 2025 would rise by 8.21% to about $673,427 in July.
