Pension Reform
Overview
Pension reform is a policy reform that adjusts key parameters such as the contribution rate, income replacement rate, and pension commencement age, or changes the system structure itself, in order to secure the sustainability of the public pension system, whose fiscal imbalance is deepening due to population aging and population decline, while maintaining its function of old-age income security. In Korea, discussions on parametric reform and structural reform centered on the National Pension (국민연금) gained momentum in the 2020s, and the 2025 amendment to the National Pension Act (국민연금법) achieved the first result by simultaneously adjusting the contribution rate and the income replacement rate.

1. Background: Fiscal Imbalance and Fund Exhaustion Outlook
Since its introduction in 1988, the National Pension was designed with a low-burden, high-benefit structure, and even after two reforms in 1998 and 2007, its fiscal imbalance accumulated. According to the government's financial projection results, the accumulated fund is projected to peak in the mid-2040s and then decline, being exhausted in the mid-to-late 2050s. Total liabilities (the present value of future pension payments) are estimated to substantially exceed nominal GDP, bringing the issue of burden-shifting across generations to the fore as a key issue.
2. Parametric Reform and Structural Reform
Pension reform is broadly divided into two axes. Parametric reform is a method of adjusting the numbers of the existing system, such as the contribution rate (currently 9%), the income replacement rate (currently around 40%), the pension commencement age, and the maximum age for coverage. Structural reform is an approach that redesigns the multi-tier old-age income system including the basic pension, retirement pension, and personal pension, and also addresses an automatic adjustment mechanism (which automatically adjusts benefits according to demographic and fiscal conditions), expansion of childbirth and military service credits, and measures to close blind spots.
3. Key Points of the 2025 National Pension Act Amendment
Discussions proceeded based on the government's Comprehensive National Pension Operation Plan in 2024, and in March 2025 the National Assembly plenary session passed the amendment to the National Pension Act. The main contents are to gradually raise the contribution rate from 9% to 13% and to increase the income replacement rate from 40% to 43%. The originally discussed plan for differentiated contribution rate increases by generation was excluded from the final draft due to fairness controversies and backlash from the younger generation. This amendment corresponds to parametric reform, and structural reform remained a task for follow-up discussion at the National Assembly Special Committee on Pension Reform and elsewhere.
4. Intergenerational Equity Debate
The greatest challenge of pension reform is intergenerational equity. While the older generation pays relatively low contributions and receives high benefits, awareness spread that the younger generation cannot be certain of future benefits despite higher burdens. Accordingly, discussions such as 'backlash from the younger generation,' 'differentiated burdens by generation,' and 'reducing the burden on future generations' actively took place in political circles and academia.
5. Overseas Cases
Sweden is evaluated as having secured fiscal stability by introducing a notional defined contribution (NDC) system and an automatic adjustment mechanism. Germany reflects sustainability factors in its pension formula, and Japan automatically adjusts benefit levels through a macroeconomic slide. Countries that pursued privatization, such as Chile, have recently entered re-reform discussions, and each country is revising its system in the direction of resetting the balance between burdens and benefits amid low growth and population aging.
Recent Trends
2024–2025 is assessed as a turning point for Korea's pension reform. In 2024, the government announced a comprehensive operation plan including an increase in the contribution rate, adjustment of the income replacement rate, and differentiated burdens by generation; then, in March 2025, as the National Pension Act amendment passed the National Assembly, parametric reform was confirmed with a contribution rate of 13% and an income replacement rate of 43%. Accordingly, a schedule was established for contributions to be raised by a certain margin each year. However, structural reform tasks such as introducing an automatic adjustment mechanism, reforming the basic pension, revitalizing retirement and personal pensions, and closing blind spots remain at the discussion stage, and follow-up legislative discussions are continuing centered on the National Assembly Special Committee on Pension Reform. Meanwhile, debates over the reliability and timing of reflecting financial projection results, concerns about expanded burdens on young people, small business owners, and special employment workers, and equity issues with special occupational pensions such as the Government Employees Pension, Military Pension, and Private School Pension also remain major issues. Experts believe that whether an automatic adjustment mechanism reflecting price and wage growth rates and demographic changes is introduced will determine mid- to long-term fiscal soundness.
