Pensions in Spain Rise Over 20% Since 2022 Due to Linkage to Inflation
The ongoing revaluation of pensions in Spain, tied legally to the Consumer Price Index (CPI) as established in the 2021 pension reform, has resulted in a significant increase in pension spending, exceeding 20% since 2022. According to analysis by the think-tank Funcas, published on December 5, 2025, this indexation mechanism has added approximately €38.7 billion to pension expenditure over the past four years.
Key Drivers Behind Rising Pension Costs
The increasing costs are driven by three main factors: the growing number of pensioners entering the system, the annual increment in pension amounts linked to the average inflation rate, and the substitution effect, which reflects the difference between the pension amounts of new retirees compared to those leaving the system. María Jesús Fernández, senior economist at Funcas, explains these dynamics highlighting their combined impact on pension budgets.
Since the reform spearheaded by then-Minister of Social Security (and current Governor of the Bank of Spain), Josep María Escrivá, monthly pension disbursements have grown each year as follows:
- 2.5% increase in 2022
- 8.5% increase in 2023 (due largely to high inflation after the invasion of Ukraine)
- 3.8% increase in 2024
- 2.8% increase in 2025
- Projected 2.7% increase for 2026
The estimated additional costs for these increments are €4.3 billion in 2022, €15 billion in 2023, €7.5 billion in 2024, €5.9 billion in 2025, and nearly €6 billion in 2026. These figures represent the fiscal impact only for the respective years in which the increases are applied.
Long-Term Fiscal Implications
The legal guarantee of annual pension increases and the abolition of the sustainability factor imply long-term growth in pension expenditure equivalent to between 1 and 2.7 percentage points of Spain’s GDP by 2050, as reported by the Independent Authority for Fiscal Responsibility (AIReF) in their assessment of public administration fiscal sustainability.
AIReF’s budget outlook for 2025 anticipates pension spending to rise by 6.2%, with 2.8 percentage points directly resulting from revaluation linked to inflation. In 2026, pension spending is forecasted to grow by 5.1%, with 2.7 percentage points attributable to revaluation measures.
Impact on Average Pension Amounts
According to official Social Security statistics, the average pension across all types—retirement, permanent disability, widowhood, and orphanhood—has risen from €1,038 per month in 2021 to €1,316 in 2025, representing an increase of 26.7%.
For context, the average pension that was €1,038 in 2021 saw incremental rises year-by-year to €1,053 in 2022, €1,143 in 2023, €1,186 in 2024, and €1,219 in 2025. Projections for 2026 estimate a rise to €1,252 if the current proposed increases are approved by the Congress of Deputies. Notably, the overall average pension amount in 2025 has been further lifted by the ingress of new pensioners who generally receive higher pensions, thereby pushing up average payouts.
The Exponential Nature of Pension Cost Growth
Miguel Ángel García, an expert at Fedea and professor of applied economics at the Universidad Rey Juan Carlos, underscores that pension cost growth is exponential as increases accumulate year after year on already elevated base amounts. He highlights that the 8.3% increase in 2023 alone implies an estimated long-term cost of approximately €100 billion, factoring in the average life expectancy of pensioners beyond age 65. ### Legislative Framework and Evaluation Mechanism
The 2021 law’s primary objective was not to cap pension spending but to safeguard pensioners’ purchasing power and strengthen the financial base of the pension system. The legislation mandates annual pension revaluation at the start of each year based on inflation data while requiring the government to carry out a comprehensive evaluation every five years. This review must be conducted in social dialogue with unions and employers and must include proposals to maintain pension purchasing power if any deviations arise.
Should the evaluation produce proposals, these must be submitted to the parliamentary Commission for Monitoring and Evaluation of the Toledo Pact agreements. Moreover, as per the most recent Toledo Pact recommendations, the Congress of Deputies is obliged to perform a general review and compliance evaluation of these pension reform recommendations at least five years after their initial approval.
Outlook and Ongoing Reform Discussion
The latest formal recommendations by the Toledo Pact commission were finalized in November 2020. Following that, the commission initiated a process to update and renew its proposals. The process began with a hearing by AIReF Chair Cristina Herrero.
Outstanding reform issues under review include periodic citizen information on their pension entitlements and revising survivor and orphanhood benefits, as highlighted in recommendations 7 and 13 of the existing pact.
