With the Spanish general election less than three weeks away, the future of the pension system has become one of the most contentious issues of the campaign. The so-called Austrian backpack, an individual savings scheme that supplements public pensions, has resurfaced as a possible reform, reigniting a familiar ideological clash between the main parties.
Spain currently spends roughly 14.5 billion euros a month on contributory Social Security pensions, according to official data from September 2026, a 6.3% increase year-on-year. More than 9.5 million pensioners receive an average monthly benefit of 1,380 euros, and they are watching party proposals closely for any hint of a freeze or cut. Politicians know this demographic is decisive: pensioners are one of the most reliable voting blocs in the country.
A campaign dominated by pension promises
The debate has intensified in recent weeks. Ester Muñoz, spokesperson for the conservative Partido Popular (PP) in Congress, questioned the long-term viability of the public pay-as-you-go system. In response, the Socialist Party (PSOE) and its left-wing ally Sumar accused the PP of plotting to privatise pensions. Prime Minister Pedro Sánchez has warned that opposition leader Alberto Núñez Feijóo would demand "sacrifices" from the population if he took office.
Feijóo, for his part, has pledged to uprate pensions in line with inflation and insists he will "in no case" question the public system. He has also promised to "guarantee" that young people will receive pensions in the future. The PP points out that the only government to freeze pensions was the PSOE under José Luis Rodríguez Zapatero.
The dispute reflects the anxieties of three groups: pensioners who fear losing purchasing power, workers who see part of their wages go into a common pot and doubt they will get it back, and young people entering a precarious labour market with low wages and ever-later retirement ages.
What is the Austrian backpack?
The Austrian backpack, officially known as Abfertigung neu, was introduced in Austria in 2003 to replace traditional redundancy pay. Employers contribute 1.53% of a worker's gross monthly salary into an individual account, which belongs to the employee. The fund can be drawn on in case of unemployment, to start a business, or left to accumulate until retirement, where it supplements the public pension. If the worker dies, the money is not lost.
Similar systems exist elsewhere in Europe: Italy has the TFR, funded by 7% of salary. The key feature is portability—the money follows the worker from job to job, hence the "backpack" metaphor.
In Austria, the fund's returns have been modest, averaging around 2% per year, according to a NEOS MP. From 2028, Austrian workers will be able to choose a riskier model with more equities, or transfer the fund to a pension fund for supplementary income.
Supporters and sceptics in Spain
In Spain, the idea has been championed by economists from Fedea, including José Ignacio Conde Ruiz, Florentino Felgueroso and José Ignacio García Pérez, who analysed its potential introduction in 2011. They argue that portability would make it easier to change jobs without losing rights, and that it would create a personal safety net. The Bank of Spain also defended the concept for years; its former governor, Pablo Hernández de Cos, presented it as a possible answer to the system's long-term funding problems.
However, critics warn that the Austrian backpack is not a silver bullet. Spain's public debt stands at 99.7% of GDP—around 1.75 trillion euros—and the unemployment rate remains above 10%. With 22.8 million people employed and average gross earnings of 29,540 euros a year, many workers question whether the system can sustain itself. The Austrian model does not replace the public pension; it is a supplement, and its returns are low. Some analysts argue that introducing it in Spain would do little to solve the structural deficit, and could even undermine the principle of solidarity that underpins the public system.
As the election approaches, the Austrian backpack has become a symbol of the broader debate about generational fairness and the sustainability of Europe's welfare states. The outcome on 29 November will not only shape Spain's pension policy but could also send signals to other countries grappling with similar demographic pressures.
