10,000 Monte Carlo simulations, 33 coupling rules fired, three structural traps all triggering at once.
France's budget deficit tripled in a single month. The Banque de France governor warned that the country is "in danger" if the 2026 deficit is not contained. Debt servicing costs have surged from €36.2bn in 2020 to €59.3bn in 2026. The IMF projects debt climbing to 130% of GDP by 2030.
These are headlines. What they don't tell you is what happens when the structural forces behind them interact over a decade.
France's GDP per capita drops from $48,982 to $46,134 by 2035. A 5.8% decline under average conditions, not a crisis scenario. The full range: P10 $32,605 (-33%), P90 $62,233 (+27%).
1. Tax Wedge Employment Drag. France's labour tax wedge sits at 45.2%. The rule fires above 43%: high taxes choke hiring, shrink the revenue base, and make the debt problem worse.
2. Fiscal Tightening. Public debt crosses 120% of GDP, reaching 124.4% by 2035. Austerity pressure and service cuts follow. The government cannot spend its way out.
3. Ageing Drag. Population 65+ hits 26.8%, passing the 25% threshold. Fewer workers, lower output per head. The dependency ratio shifts against the working-age population.
On top of all three, petrol above $2.00/L fires Fuel Pressure twice. Inflation nearly doubles to 3.8%. Electricity up 28%.
Of the 13 positive rules that fired, almost all are tech-driven: R&D Spillover (fires twice), AI Dividend, Digital Flexibility. France's innovation base carries the entire P90 upside scenario ($62,233).
But high-tech exports are already falling: 23.1% to 16.8% (-27%). R&D spending is flat at 2.16%. The escape hatch exists, but it is narrowing.
France is not facing a crash. What the simulation shows is a slow structural squeeze from multiple directions at once. The tax system is too heavy to create jobs. The debt load triggers austerity. The population is ageing past the tipping point. And the only upside is innovation, which is showing signs of erosion.
20 negative coupling rules fired. 13 positive. The distributions don't give a definitive answer. That is the point.
The complete deep dive includes all coupling rule triggers, cost of living breakdown, housing analysis, and the full P10/P50/P90 distributions.
