A comprehensive reform of the pension system is needed in the near term, combining higher pension contributions, increased effective retirement ages, and some reductions in benefits to secure the system for future generations.
Luxembourg faces rapidly rising pension expenditure over the next decades (Figure 2), mainly from the retirement of the large cohorts of workers who entered the labour market from the late 1980s. The number of pensioners will more than triple over 2024-2070, requiring an increase in employment of 1.2 million workers to maintain a stable ratio of workers to pensioners. This would further strain infrastructure and housing, underlining that the pension system is unsustainable under current rules, despite large pensions reserves accumulated over the past two decades.
Balancing the pension system in the long term requires a comprehensive reform. The horizon over which periodic reviews assess the balance of the system needs to be extended from 10 to 50 years. Setting a steady-state contribution rate that balances the system over 50 years and phasing it in early would ease the burden on future generations by allowing larger working-age cohorts to contribute more, while the pension reserve fund would grow through financial returns.
Raising contributions to a rate that can be maintained over the long term and raising the effective retirement age, which is the lowest in the OECD, would put the system on a sustainable footing. Eligibility for early retirement should be tightened by removing educational years from the calculation of contributory years, aligning benefits with actual work history. On top of helping to balance the pension system, this would also help to improve intra-generational fairness by mainly affecting highly-educated workers, while protecting lower-educated ones. At the same time, early and statutory retirement ages should be raised to match gains in life expectancy.
Pension benefits need to be brought more in line with other OECD countries. Currently, the relative income of older people is the highest in the OECD. Shortening the transition to the lower replacement rates of the 2012 reform from 40 to 25 years would contribute to a slower depletion of assets in the pension reserve fund. Switching from nominal wage indexation of pensions in payment to inflation indexation – as is common in OECD countries – would ensure that current pensioners contribute to the reform effort.
If all policy levers are used and reforms are enacted in the next few years, the extent of required changes would be manageable. Legal retirement ages would increase by about 1½ years per decade; the replacement rate at retirement age for a worker with a full career would remain around 75%; and the joint pension contribution of employers and employees would increase from 16% to 18%. While these changes are significant, they appear manageable relative to the radical changes that would be required at a later stage if no reform is undertaken, such as large increases in pension contributions or sharp reductions in replacement rates from the late 2040s.
