Taking into account the final inflation data for October, toll rates could rise by 2.3% in 2026. The value is calculated based on the inflation figures, excluding housing, for October, for the mainland (2.2%), plus 0.1% compensation to concessionaires, according to a report by ECO.

The National Institute of Statistics (INE) has confirmed that annual inflation slowed to 2.3% in October, from 2.4% in September, while the underlying inflation rate accelerated slightly to 2.1% (2% in September).

The annual rate for last month, excluding housing, which serves as a reference for determining the amount by which toll companies can increase tolls in the following year, was 2.2%. This percentage is increased by 0.1%, resulting from an agreement reached in 2022 with highway concessionaires to compensate them for halting a roughly 10% increase in 2023. In other words, tolls could rise by 2.2% in 2026.

By law, highway concessionaires must submit their toll revision proposal to the Government by November 15th, to take effect on January 1st of the following year, with the State having 30 days to respond.

After remaining unchanged in 2020 and 2021 due to negative variations in the reference rate, toll rates increased by 1.83% in 2023 and rose by more than 2% and 2.2% in 2024 and 2025, respectively.
