Economic outlook & institutional lenses
Forecasts change. These cards show the latest anchors included in this version and competing interpretations of the 2026 budget. They are context for the game, not hidden assumptions in the sliders.
1.8%
2026 inflation forecast
STATEC's August update forecasts 1.8% inflation for 2026 and 2.1% for 2027 after energy pressures eased.
+0.5%
Q2 employment signal
Preliminary data indicated employment growth strengthening by roughly 0.5% quarter-on-quarter in Q2 2026.
0.6%
2025 GDP growth
The June Note de conjoncture reported 0.6% real GDP growth in 2025 and stressed major external uncertainty around the 2026 path.
2029
Medium-term pressure
Budget and chamber analyses expect persistent central-government deficits through the multiannual horizon, with ageing and social-security financing a core risk.
Chambre de Commerce
Prioritise productivity and spending quality
Warns that State expenditure is growing too quickly relative to the economy, asks for measurable effectiveness, stronger prioritisation, and reforms supporting competitiveness and long-term sustainability.
Chambre des Salariés
Use fiscal room for households and social investment
Argues the budget underweights purchasing power, housing and social investment, and disputes the idea that Luxembourg's fiscal position requires a primarily restrictive response.
Chambre des Métiers
Restrain structural growth, but invest in housing
Calls the 2026 budget a missed reform turn, questions growth assumptions, advocates performance-oriented spending and stronger, targeted support for housing supply and construction.
CNFP
Watch fiscal rules and forecast reliability
The independent fiscal council evaluates Luxembourg's compliance with budget rules and the reliability of forecasts. This simulator therefore keeps accounting effects separate from macroeconomic predictions.
LSAP fiscal paper
More progressive taxation
Proposals include a progressive personal wealth tax, stronger taxation of real-estate gains and harmful products, targeted ecological compensation and selective lower VAT rates rather than a general VAT increase.
déi Lénk 2023
Shift taxation toward wealth and capital
Proposals include a personal wealth tax, progressive property taxation, higher corporate taxation for larger firms, and closer tax treatment of capital income and labour income.

Government-first viewThese are announced, agreed or adopted measures—not endorsements. A visible status badge distinguishes laws, bills, agreements and estimates.
How the model works
A budget is not a household spreadsheet. Taxes affect behaviour, growth affects receipts, and Luxembourg's cross-border economy makes estimates unusually sensitive. The model keeps official figures and assumptions separate.
1 · Annual baselines
The voted 2026 State budget is the fixed foundation. Later years show amendments against that foundation, not a complete forecast. The forthcoming 2027 draft has its own prepared comparison section. The borrowing ceiling is not treated as revenue or as the deficit.
2 · Status before politics
Government measures show whether they are an adopted law, a bill, an announcement or a tripartite agreement. Party and institutional origins remain visible but secondary in the advanced library.
3 · Published versus assumed costs
Published costings are used where available. If an official design or party proposal has no dependable annual total, the card says so and the adjustable amount is explicitly a simulator assumption.
4 · Defence trajectory
The defence card compares your target with the official 2.1%, 2.2% and 2.3% GNI path for 2027–2029. The 3.5% NATO core-defence commitment is a 2035 goal, not current spending.
5 · Political lens
Each measure carries a small heuristic economic and social/ecological score. It is explanatory, not a scientific ideology test, and it never changes the fiscal calculation.
6 · Evidence and experiments
Published costings, calculations and open experiments are labelled separately. Scenario inputs are adjustable; social and economic outcomes remain uncertain. There are no invented probabilities of success.
