Luxembourg’s public pension system will reach a tipping point as early as 2026, when pension spending will exceed contribution revenues for the first time. This is the main conclusion of a technical assistance report by the International Monetary Fund (IMF), published this Wednesday 17 December at the request of the Ministry of Finance, devoted to assessing the financial projections for Luxembourg’s pension system.
According to the IMF, this crossing of the threshold marks the entry of the scheme into a long-term deficit on an annual basis, even though the system will continue to operate thanks to the substantial reserves accumulated over the years. Legally, this event—described as “Event 1” in the report—triggers the application of Article 225 of the Social Security Code, which provides for indexation of pensions limited to inflation and capped at 50% of real wage growth when expenditure exceeds contributions.
Two years ahead
Initially anticipated for 2028, this tipping point has now been brought forward by two years. The IMF attributes most of this change to the downward revision of employment growth assumptions. The new macroeconomic projections assume much weaker growth in the number of contributors between 2024 and 2026, following the recent slowdown in the labour market. This revision alone accounts for more than 80% of the worsening in the projected balance to 2026.
This diagnosis comes as the government announced, on 3 September, an initial reform of the pensions system, due to come into force on 1 January 2026. The central measure is an increase in the overall pension contribution rate from 24% to 25.5% of gross salary, shared equally between employees, employers and the state. For employees, this means an increase of around 0.5 points in their personal contributions, while the self-employed, who pay the employee and employer portions alone, will see their effective rate rise from 16% to 17%.
The reform also provides for a gradual tightening of the conditions for access to early retirement at age 60, with no change to the statutory retirement age, which will remain at 65, or to the rules for early retirement at age 57 for long careers. The length of contribution required for retirement at 60 will be increased by a total of eight months, spread between 2026 and 2030, to encourage slightly longer careers.
Still significant margins
The IMF stresses that these measures are in the direction of an early adjustment, but that they do not alter the fundamental trajectory of the system. Long-term projections show that, without further reforms, the scheme’s reserves would fall below the legal threshold of 1.5 times annual expenditure by the end of the 2030s, around 2039, which would then require an increase in the contribution rate. The total exhaustion of reserves is projected at around 2045.
The report stresses the stability of these deadlines over time: for almost ten years, projections of reserve depletion have varied by only two years despite successive economic shocks and methodological revisions. According to the IMF, this consistency strengthens the credibility of the sustainability diagnosis.
The institution also dismisses the idea that improving the financial returns on the Compensation Fund could be enough to solve the problem. Even with more optimistic return assumptions, critical events would only be postponed by one to three years, an effect deemed insufficient to offset the demographic and economic imbalances at work.
In conclusion, the IMF believes that while the Luxembourg pension system remains well managed today and still has significant financial margins, the tipping point of 2026 confirms that the current parameters do not guarantee long-term sustainability. The measures already taken by the government represent an initial adjustment, but the Fund recommends anticipating other reforms, introduced gradually, in order to avoid more brutal corrections in the decade to come.
