Sweden gave citizens 465 pension funds to choose from and quietly built one fund for the people who'd never choose at all — that fund now beats 87% of the people who did
the problem
Offering people unlimited choice in a decision most will never actively make just means most people end up with whatever happens by default, unexamined
background
When Sweden launched its Premium Pension System in 2000, requiring workers to direct 2.5% of pensionable income into individually selected funds, the government's approach was to maximize choice: an initial catalog of 465 approved funds were available for citizens to research and pick from, reflecting a design philosophy that more options and more personal control would produce better outcomes for savers than a single government-managed fund.
Anticipating that many citizens would never make an active choice at all, the system's architects created AP7 (Sjunde AP-fonden), a state agency tasked with managing a low-cost default fund — originally called Premiesparfonden, later restructured as AP7 Såfa — that anyone who declined to actively select funds would be automatically enrolled in, with no obligation to ever revisit that choice.
the move
AP7's default fund runs a low-cost, broadly diversified, age-adjusted index strategy, requiring no active decisions from savers at any point — the fund simply exists as the outcome for everyone who never chose otherwise, alongside the hundreds of actively managed funds available to whoever wanted to pick their own.
the payoff
According to the Swedish Pensions Agency's 2025 analysis, just over 13% of savers who actively selected their own funds outperformed AP7's default fund over the long term — meaning roughly 87% of people who spent time and effort choosing their own funds would have done better simply doing nothing. The agency's data additionally found that the more often a saver switched funds, the worse their average returns tended to be, and over the preceding decade AP7's default produced an average annual return of 13.5% against an average 7.8% for actively chosen private funds.
what came after
Sweden's Premium Pension System, and AP7's default fund performance specifically, is now a widely cited real-world natural experiment in choice architecture and passive-versus-active investing, referenced in pension-policy design across other countries considering how much emphasis to place on expanding fund choice versus engineering a strong, low-cost default for the majority who will never actively choose.
