Are Pensions an Intergenerational Bomb in Spain? Rethinking the Silver Economy and the Future of Millennials

Spain’s pension system is nearing a demographic tipping point. With retirees holding a record share of national wealth and younger generations stuck in gig work and housing insecurity, the generational contract is under stress. Unless reforms bridge the gap between a thriving silver economy and struggling youth, Spain risks deepening inequality and long-term instability.

Spain’s looming pension crisis through the lens of intergenerational wealth transfer, examining the changing economic influence of the elderly, the myths surrounding millennial economic power, and the policy crossroads shaping Spain’s future.

Picture this: a family Sunday lunch in Spain, everyone talking over each other, but one topic consistently emerges—who’s really footing the bill for the future? Just last week an uncle, recently retired, boasted about his comfortable pension while my cousin, a millennial, grumbled about his gig contract and rent prices. This living room tension mirrors a countrywide debate over pensions, wealth, and which generation is carrying the most weight. Let’s peel back the myths and numbers.

The Not-So-Hidden Wealth of Baby Boomers: Who Actually Has Economic Power?

For years, the narrative has centered on millennials as the new engine of the economy—tech-savvy, trend-setting, and poised to drive consumption. But research shows this view misses a much starker reality: Spain’s true economic power lies with its oldest citizens. Baby boomers, those born between 1945 and 1964, now control an estimated 65% of the nation’s total wealth. This is not just a statistic; it’s a seismic shift in who holds the keys to Spain’s financial future.

Recent data paints a clear picture of this generational divide. Households led by someone aged 65 to 75 possess, on average, €226,000 in net assets. That’s nearly triple the wealth of households headed by 35- to 44-year-olds, who average just over €76,000. The gap is even wider for those under 35, whose accumulated assets often fall below €100,000. The numbers are not only striking—they’re growing. Studies indicate that older cohorts today have double the net assets that millennials hold at the same age, a trend that’s intensified over the past two decades.

This concentration of wealth among the elderly is unprecedented in Spain’s modern history. As one analyst put it,

“The relative wealth of the elderly now surpasses any historical precedent. Today’s retirees are, on average, far richer than their counterparts from previous generations.”

The reasons are complex but rooted in structural advantages: many baby boomers bought homes when prices were low, benefited from stable employment during economic booms, and now enjoy generous public pensions. These factors have combined to create a generation of retirees with financial security that younger Spaniards can scarcely imagine.

The implications ripple across society. With such a large share of wealth, baby boomers have become a dominant force in sectors like health, tourism, and personal services—fields now adapting to the so-called “silver economy.” Their spending power shapes markets and influences everything from advertising to public policy. Meanwhile, millennials and younger generations, despite their visibility in the workforce and media, struggle with precarious jobs, high housing costs, and limited prospects for asset accumulation.

There’s a growing sense of imbalance. As one commentator observed,

“Confusing activity with purchasing power is a mistake. Just because a generation is visible doesn’t mean it holds the wealth.”

The data backs this up: the economic engine is running on the fuel of accumulated assets, not just youthful energy or innovation.

Looking at the broader European context, the pattern is similar. Older generations are not just more secure—they’re often less likely to experience poverty than their younger counterparts. In Spain, the wealth gap between young and old has reached historic highs, and projections suggest it will only widen unless addressed.

As Spain faces demographic changes and ongoing pension reforms, the question of who holds economic power is more than academic. It’s a reality shaping the future of both the welfare state and the prospects of younger generations. The numbers are clear: for now, the boomers are firmly in the driver’s seat.

The Expanding Pension Burden: Myths, Realities, and Generational Fallout

Spain’s pension system is making headlines for all the wrong reasons. In May, state pension payments soared to a record-breaking €13,532 million, covering more than 10 million recipients. That’s a 6.3% increase from the previous year, and it marks a new high in the country’s history. The numbers are staggering, but what lies beneath is even more complex—and, for many, worrying.

For years, the narrative has been that millennials—those born between the early 1980s and mid-1990s—are the driving force of the economy. They form households, have children, and fuel consumption. But this view, while comforting, misses a crucial reality: the relative wealth of Spain’s elderly population is at an unprecedented level. As one analyst put it, “The truth is that the wealth of the elderly far exceeds any historical precedent, and this will have repercussions for pensions.”

Research shows that the pension system is now the largest single item in Spain’s public budget. It’s a cost that cannot easily be trimmed, and it’s only set to grow as the baby boomer generation retires. The Bank of Spain has recently downplayed immediate sustainability concerns, but long-term questions remain. The country has more social security contributors than ever before, yet the average contribution per worker is lower than in previous generations. Fewer hours worked and more precarious employment mean that the system’s foundation is less stable than it appears.

One of the most persistent myths is that today’s workers are building up a personal pension pot for their own retirement. In reality, current contributions are used to pay today’s retirees, with future pensions depending on the next generation of workers. This pay-as-you-go model worked when the population pyramid was wide at the base—many young workers supporting fewer retirees. Now, with an aging population and fewer young contributors, the balance is shifting dangerously.

The generational divide is stark. Baby boomers, who benefited from stable jobs, affordable housing, and a growing economy, now hold around 65% of Spain’s wealth. Their assets have doubled over the past two decades. In contrast, millennials and younger cohorts face a much tougher climb. The average household headed by someone aged 65-75 holds over €226,000 in assets, while those led by 35-44-year-olds barely surpass €76,000. The gap is widening, not shrinking.

This concentration of wealth among the elderly is reshaping the economy. Sectors like healthcare, tourism, and personal services are increasingly tailored to the “silver economy”—the spending power of older consumers. Meanwhile, younger generations, with less disposable income, have less sway over market trends than headlines suggest. As the analyst notes, “Confusing activity with purchasing power is a mistake. Just because a cohort is visible doesn’t mean it holds the wealth.”

With pensions now crowding out other public spending priorities, the debate is no longer academic. Choices will have to be made: maintain pension levels, cut other services, or rethink the entire system. The risk, experts warn, is that without action, Spain could see growing social and economic tensions between generations—an “intergenerational bomb” that no one seems ready to defuse.

Inheritance and the Illusion of a Level Playing Field: Will Millennials Catch Up?

For years, the narrative has been that millennials—those born between 1981 and the mid-1990s—are the new economic powerhouse. They are expected to form households, raise children, and drive consumption. But beneath this optimistic forecast lies a stark generational divide in wealth, one that inheritance alone may not resolve.

Recent projections suggest that Spanish millennials could receive average inheritances of around €250,000 in the coming decades. At first glance, this seems like a potential equalizer. However, as research shows, the reality is far more complex. The European Statistical Office has warned that this “largest transfer ever” of intergenerational wealth is unlikely to close the gap between rich and poor. Instead, it may deepen existing inequalities, as inheritances are set to be distributed highly unevenly.

The numbers tell a clear story. In Spain, households led by those aged 65 to 75 hold an average net worth of €226,000, while those headed by individuals aged 35 to 44 average just €76,000. For families under 35, wealth drops even further. This generational wealth gap has only widened over time. According to the Bank of Spain, people born in 1960 had double the net wealth at age 45 compared to those born in 1980. The ability to accumulate assets has been halved in a single generation.

The reasons are rooted in both structural advantages and historical timing. Baby boomers and the generation before them benefited from affordable housing, stable jobs, and expanding economies. They now enjoy robust public pensions and own much of the country’s property. Millennials, by contrast, came of age during two major economic crises—the 2008 financial crash and the 2020 pandemic. These events left many asset-poor, facing precarious employment and limited opportunities to save or invest.

As a result, millennials are increasingly reliant on inheritance as a means of catching up. Yet, as the source material highlights, this windfall will not be evenly spread. “Some will receive millions, others nothing,” the analysis notes. Families with significant assets will pass on wealth, while those from working-class backgrounds may have little or nothing to bequeath. The effect? A further entrenchment of inequality, as the children of the wealthy inherit not just money, but also the security and opportunities that come with it.

“An average inheritance of €250,000 sounds impressive, but it masks a reality where only a minority will benefit. The rest will continue to struggle in an economy that increasingly rewards those who start ahead.”

This dynamic is not unique to Spain. Across Europe, the so-called “silver economy” is reshaping markets and social policy. Older generations now control a record share of wealth, influencing everything from housing to healthcare. Meanwhile, the promise that millennials will one day inherit enough to level the playing field is, as studies indicate, more illusion than reality. The intergenerational transfer of wealth risks reinforcing privilege, not dismantling it.

Can Spain Rewrite the Generational Contract Before It’s Too Late?

Spain’s pension debate is no longer a distant warning—it’s a present-day reckoning. The country’s aging population, now wealthier than any previous generation, holds a growing share of both economic power and electoral influence. As research shows, pension expenditure has reached record highs, with the Social Security system paying out over €13.5 billion in May alone. This is not just a budgetary footnote; it is the largest single expense in the Spanish state and one that is only set to grow as the baby boomer generation retires in full force.

Yet, the political courage needed to reform pensions often collides with the reality of electoral math. Older voters, who benefit most from the current system, are more likely to turn out at the polls and resist any cuts to their benefits. As the source material notes, “Políticamente los mayores suelen ser mayoría votante y han logrado preservar sus beneficios, pensiones, ventajas fiscales, propiedades inmobiliarias con bajos impuestos, todo ese rollo.” This dynamic makes it difficult for policymakers to push through changes that might be unpopular in the short term but necessary for long-term sustainability.

Several options are on the table. The so-called ‘Austrian backpack’—a portable, individualized pension savings account—has been floated as a way to modernize Spain’s system and give younger workers more control over their retirement security. Shifting Social Security models and boosting labor market opportunities for youth are also under discussion. But these reforms require more than technical tweaks; they demand a societal willingness to rethink the generational contract.

The underlying challenge is not simply economic. It is about fairness and the future of social cohesion. The current system, built for a time when the population pyramid was wide at the base and narrow at the top, now faces the opposite demographic reality. Millennials and younger cohorts, having weathered two major economic crises in their formative years, find themselves with far less wealth and fewer opportunities than their parents or grandparents did at the same age. Meanwhile, the promise that inheritance will solve these disparities is, as one analyst put it, “de broma”—a joke—since wealth transfers will only widen the gap for those already left behind.

Sustainable prosperity, then, cannot be achieved through zero-sum blame games or by pitting generations against each other. As the transcript highlights, “Aquí es preciso un cambio de chip, dejar de pensar en términos de ganadores, perdedores, ricos, pobres, porque por edad y buscar un nuevo pacto social en el que la experiencia de la vejez y el empuje de la juventud se complementen en lugar de competir por los recursos existentes.” In other words, Spain must move beyond simplistic narratives and embrace a new social pact—one that balances the dignity of the elderly with the aspirations of the young.

Whether Spain can rewrite its generational contract before the system buckles under its own weight remains an open question. But one thing is clear: the time for hard conversations, shared sacrifices, and bold reforms is now. The future of Spain’s prosperity—and its social peace—depends on it.

TL;DR: Spain’s pension system faces an unprecedented intergenerational challenge, with older generations wielding increasing economic power and a growing strain on public finances. Meaningful reform must balance dignified retirements and fair opportunities for young people to ensure lasting prosperity.
