The steady outflow of older investors from equities as they enter retirement could exert gradual but persistent downward pressure on stock markets, according to Manuel Buchmann, a demographer at Basel-based Demografik.
Switzerland has recorded net outflows of pensioners exceeding new entrants to the workforce every year since 2019, straining pay-as-you-go pension systems and reshaping capital allocation patterns. While Buchmann cautioned against framing the trend as an imminent collapse, he noted that financial markets are not immune to the demographic shift. The aging population is already forcing adjustments in labor markets, business models and individual savings behavior, he said.
The Swiss pension system’s reliance on immigration to maintain balance has been quantified in recent studies. Demografik’s analysis, conducted alongside the ‘No 10 Million Switzerland’ initiative, estimates that limiting net migration would increase the AHV pension fund’s projected deficit by between 4 billion and 6 billion Swiss francs annually. The shortfall would persist through the end of the century, even after accounting for future benefit payments from immigrants, due to their above-average employment rates and wage levels.
Buchmann emphasized that immigration has acted as a stabilizing force, delaying the need for painful reforms such as higher payroll taxes, reduced benefits or extended working lives. However, demographic pressures in key source countries—including Germany, Italy, France, Spain and Portugal—are eroding the pool of potential migrants, while Switzerland’s economic competitiveness remains tied to wage levels and cost-of-living dynamics.
The demographic transition is also reshaping private savings behavior. With life expectancy rising and healthy lifespans expanding, the final years of retirement are becoming the most expensive phase of life. Medical and long-term care costs surge in the years preceding death, while active retirees increasingly allocate savings to travel and leisure. Buchmann highlighted a persistent gap in financial literacy, particularly among older adults who underestimate longevity risks and younger cohorts who delay engaging with markets.
Men tend to exhibit higher financial knowledge on average, though women often achieve superior investment outcomes when given the opportunity to participate. Buchmann advocates for earlier financial education, arguing that individuals who begin planning at 60 are already late to the process. The cumulative effect of these trends—gradual asset sales by retirees, rising longevity costs and uneven financial preparedness—could reinforce a structural headwind for equities over the coming decades.
