The International Monetary Fund published a selected issues paper on Liechtenstein’s long-term fiscal outlook, estimating cumulative annual spending pressures of around 3.5 percent of GDP by 2050 driven by population aging, the climate transition, and higher security needs. The analysis, based on a Marginal Abatement Cost Curve framework, cohort-component demographic modeling, and cross-country benchmarking, attributes the pressures mainly to climate mitigation and adaptation (1.7 percent of GDP) and pensions (1.5 percent), with security accounting for 0.3 percent. The paper notes that consistent fiscal surpluses, near-zero public debt, and substantial net assets provide space to address these costs, and recommends embedding long-term projections more systematically into budget frameworks through regular sustainability assessments and independent evaluation.

International Monetary Fund projects Liechtenstein’s long-term spending pressures could reach 3.5 percent of GDP by 2050
The International Monetary Fund published a paper on Liechtenstein’s long-term fiscal outlook, projecting cumulative annual spending pressures of around 3.5 percent of GDP by 2050 driven by population aging, the climate transition, and higher security needs. Using a Marginal Abatement Cost Curve framework, demographic modeling, and cross-country benchmarking, the paper attributes most pressures to climate mitigation, adaptation, and pensions, noting that Liechtenstein’s strong fiscal position provides space to address these costs while recommending more systematic integration of long-term projections into budget frameworks.
