The Marine Le Pen fiscal plan is being read by some observers as a serious attempt to reassure bond markets ahead of a potential change of government in France. The arithmetic beneath the headline figures tells a more uncomfortable story.
The Rassemblement National has presented a counter-budget promising to cut the public deficit from 5.4% of GDP this year to 3.7% next year and 2.8% by 2028. Le Pen frames this not as austerity but as a ‘recovery cure.’ The savings required to reach those deficit targets total €136bn, and the plan identifies three main sources: tax evaders, migrants and the European Union. One is tempted to ask why no previous government thought of this.
The Marine Le Pen Fiscal Plan’s Growth Assumption Does the Heavy Lifting
The entire consolidation path rests on a macroeconomic assumption that deserves more scrutiny than it has received. The RN proposes to squeeze €100bn in structural adjustments in 2027 and 2028 while simultaneously doubling the economic growth rate, from 0.9% next year to between 1.7% and 1.8% from 2028 to 2030. No negative growth effects from a fiscal consolidation of that scale appear to have been modelled into the projections. The plan promises a primary surplus in early 2028, which would then be used to reduce public debt.
ING Think has analysed the delivery risks and flagged a structural tension at the heart of the proposal: the RN’s plan combines fiscal consolidation with €69.3bn of tax cuts and new spending in 2027 alone, comprising €53.2bn in revenue cuts and €16.1bn in new expenditure. Cutting the deficit while simultaneously deploying that volume of stimulus is not impossible in theory, but it requires the savings side to materialise in full and on schedule. The plan’s savings side is where the scepticism concentrates.
Four Pillars, Each With Its Own Problems
The RN expects €37bn in savings from Social Security. The measures are vague: reducing hospital costs and streamlining patient pathways is said to save €8bn, combatting undue spending another €10bn, and fixing the pension system €15bn. One concrete pension measure, reported by Les Echos, is increasing the contribution period required to validate a quarter of a pension entitlement, from four weeks to twelve. The RN estimates this would offset Le Pen’s retirement-at-62 proposal, at an estimated cost of €10bn. Other economists place the cost considerably higher, in the tens of billions.
The second pillar is fighting tax fraud, where the RN expects to raise €33bn. In previous budget years the French government has never successfully recovered more than €15bn through enforcement, even with AI and data-mining tools. The plan’s centrepiece here is a withholding tax system for VAT, projected to raise €18bn. Estimates for VAT fraud range from the government’s own figure of €6bn to INSEE’s €26bn. The RN appears to have chosen the number that made the arithmetic work.
The third pillar targets migration. The RN aims to recoup €29bn from migrants by 2031, primarily by excluding foreigners from family and welfare benefits, which it estimates at €18bn. Independent estimates put the savings from such a crackdown at around €5bn. The constitutionality of excluding non-citizens from social benefits will almost certainly face legal challenge.
The fourth pillar is a cut to France’s EU contribution of around €20bn, roughly two thirds of the current total including customs duties paid to Brussels. Unilaterally withholding that sum would represent a fundamental breach of France’s treaty obligations. It is difficult to see how this measure, above all others, is supposed to reassure bond markets.
What the Debt Target Conceals
Le Pen has also proposed a referendum on a constitutional ‘golden rule’ for the budget, presented as a signal of fiscal discipline to investors. According to Yahoo Finance, the RN’s plan aims to bring public debt down to 112% of GDP by 2032, compared with 119% today. That trajectory depends entirely on the savings materialising, the growth assumptions holding, and the EU accepting a €20bn reduction in French contributions without retaliation. Each of those conditions is generous. A scenario in which the deficit rises under a Le Pen government is not far-fetched; it may well be the central case.
The consensus read treats the Marine Le Pen fiscal plan as a credible-enough document to be taken seriously by markets. The consensus may be overweighting the headline deficit targets and underweighting the delivery risks buried inside. France’s spread widening suggests some investors are already doing the maths.
