The amount cut from South Korea’s basic pension because recipients also receive National Pension benefits has nearly tripled in four years, adding pressure for a review of how the two retirement programs interact.
Data from the National Assembly Budget Office cited by Korean media show that the total reduction exceeded ₩80 billion last year. About 842,000 people were affected, also a sharp increase from several years earlier.
The rule is designed to coordinate two public retirement-income programs rather than pay the full amount of each regardless of other income. But it has long faced a fairness criticism: people who paid into the National Pension for longer periods can receive a larger National Pension benefit and then see part of their basic pension reduced.
That can create an incentive problem. If workers believe additional contributions will simply be offset by lower basic-pension payments later, confidence in the contribution system can weaken. The effect is especially sensitive for lower- and middle-income retirees, for whom relatively small monthly changes matter.
The National Assembly Budget Office has argued that the mechanism needs policy review. Reform is not simple, because removing or reducing the linkage would increase public spending, while keeping it unchanged risks reinforcing the perception that long contribution histories are penalized.
The next debate is likely to focus on thresholds, reduction formulas and whether the two pension systems should be coordinated in a different way as Korea’s population ages.
