The question at hand
Weeks away from the 2027 budget, can Lecornu secure a compromise, will he have to resort to Article 49.3 again, or will the budget battle bring down his government?
The facts
On July 29, 2026, we first asked this question (read the original edition), with a starting scenario that still seemed manageable: 20% chance of an agreement, 50% chance of a budget imposed via Article 49.3*, and 30% chance of the government falling. Six weeks later, several indicators have turned red.
The French economy is slowing more than expected. On September 10, INSEE lowered its 2026 growth forecast from 0.7% to 0.4%; the government itself revised it down to 0.5% the following day — the third downward revision of the year. The causes: a collapse in construction, heatwaves estimated to have cost agriculture about 0.1 percentage points of growth, and a labor market more deteriorated than elsewhere in Europe.
This slowdown mechanically complicates the reduction of the public deficit* targeted since the start of the year: the government now admits it will not meet its 5% of GDP target for 2026.
Understanding it
The deficit is measured as a % of GDP: when growth slows, the same amount of spending mechanically weighs more heavily, even without spending an extra cent.
The public deficit isn't just "money spent in excess": it's that amount relative to the wealth produced in the year, GDP, which serves as the denominator in the calculation. When growth falls from 0.7% to 0.4-0.5% as it did this summer, GDP grows more slowly than expected. The same deficit in euros then represents a larger share of national wealth. The government must therefore find even more savings just to return to the initially targeted ratio, without having voted for a single additional expense.
The cost of debt is rising simultaneously. The rate at which France borrows over 10 years (the OAT*) reached 4.44% on September 10, its highest level since 2008. According to several estimates, the annual interest charge on the debt could approach €65 billion in 2026, several billion more than anticipated a year ago.
The government therefore has less room to negotiate. Sébastien Lecornu is seeking around €30 billion in savings for 2027, without tax increases, but now targeting a deficit of barely 4.9% of GDP — compared to 5.1% in 2025 — rather than the return below 3% promised to Brussels for 2029, which has become unattainable.
The timeline, meanwhile, is becoming clearer. The 2027 Finance Bill* (PLF) is to be presented to the Council of Ministers on September 30, 2026, before being examined by Parliament in the fall — the real political test of the new term.
The problem remains primarily political. Lecornu still lacks an absolute majority, and the Socialist Party, which facilitated the adoption of the 2026 budget in exchange for concessions on pensions, is proving much tougher this time: its first secretary, Olivier Faure, warned in late August that he saw "no suspense" regarding a compromise on a budget written by the same team. A new use of Article 49.3 could therefore trigger a motion of no confidence* far more dangerous than in the spring.
A precedent already exists: in December 2024, Michel Barnier's government fell over its own budget — the only successful no-confidence motion since 2024. Since then, no opposition had found a common majority to topple a government, due to a lack of agreement between the RN and a divided left. But the 2027 presidential election, absent from the calculation in 2024, now changes the stakes for every camp: voting for no-confidence costs less politically a few months before an election than in the middle of a term.
Several upcoming deadlines, in the coming weeks, will decide between the 3 scenarios below:
The timeline that will decide between the 3 scenarios
1September 30, 2026 — Presentation of the 2027 PLFSébastien Lecornu presents his draft budget to the Council of Ministers: the first concrete indication of the real scale of savings and concessions.
2October 2026 — Debate in the National AssemblyThe PS must take a clear stance: vote for the text, abstain, or join a no-confidence motion.
3A potential use of Article 49.3If no positive vote emerges, as in 2025 — opens a 48-hour window to file a no-confidence motion (threshold: 289 votes).
4Late fall 2026 — The risk of a special lawWithout a budget adopted on time, a special law* becomes necessary to allow the state to continue collecting taxes and functioning.
This timeline remains indicative: a compromise or a no-confidence motion can accelerate or prolong it at any time. The fate of the government will likely be decided over several weeks, not in a single, isolated vote.
Target deficit for 2027≈ 4.9% of GDP vs. ≈5% in 2026, target already compromised
Favorable, stable, or degraded
Budget négocié, 49.3 ou crise politique : quel scénario cet automne ?
What we're assessing
FavorableUn compromis permet à Lecornu de faire adopter le budget et de tenir jusqu'à la présidentielle.
StableLe budget passe via un nouveau 49.3, sans qu'aucune motion de censure ne réunisse de majorité, et le gouvernement survit affaibli.
DégradéLa bataille budgétaire tourne à la crise politique : chute du gouvernement, ou budget si bloqué qu'une loi spéciale devient nécessaire.
Favorable
10%
Unlikely
A budget compromise allows Lecornu to hold on
The government manages to secure, before or during the bill's review, a sufficiently broad agreement with part of the left and its own camp. The budget is adopted with a compromise on savings or taxation, without triggering a successful no-confidence motion. This scenario remains possible: no one has an interest in provoking an additional financial crisis just months before the presidential election, and the government can still adjust its text before its September 30 presentation.
This is the least likely of the three scenarios, and it has become even less so since July 29 (20% → 10%): Lecornu has less money to distribute to build an agreement, precisely when the PS has less interest than ever in appearing as the guarantor of an unpopular government approaching the presidential election. It remains less likely than Article 49.3, which requires no explicit agreement, and far less likely than a political crisis, which has become the default outcome as soon as no compromise is reached.
Indicators affected
Taux d'emprunt à 10 ans (OAT)4-4,2 %, détente possible↓(vs ≈4,44 % actuellement)
Déficit visé pour 2027≈4,9 %, objectif tenu→(vs objectif officiel de 4,9 %)
The France angleA credible compromise would ease the risk premium on French debt and stabilize the deficit on its targeted trajectory, even if the budget would remain very constrained and the savings very real. ↑ Rather favorable for France.
Stable
40%
Likely
A new Article 49.3 passes the budget, the government survives weakened
As in 2025, the government presents a minimalist budget, fails to secure a voting majority, and ultimately uses Article 49.3. A no-confidence motion is filed, but the opposition fails to gather the necessary 289 votes: the budget is adopted without a vote, at the cost of a significantly weakened government and structural reforms postponed until after the presidential election.
This is still the most likely of the three scenarios, but significantly less dominant than on July 29 (50% → 40%): the 2027 presidential election is approaching very quickly, and the opposition has less and less interest in letting the government finish its term quietly. It remains more likely than a compromise, which is out of reach with such a constrained budget, but it is now less likely than a political crisis: the PS has less to lose by voting for no-confidence than by appearing as the supporter of an unpopular government on the eve of an election.
Indicators affected
Taux d'emprunt à 10 ans (OAT)4,2-4,6 %, sans détente franche→(vs ≈4,44 % actuellement)
Déficit visé pour 20275-5,3 %, objectif manqué de peu↑(vs objectif officiel de 4,9 %)
The France angleNo immediate shock, but another year of political deadlock: the debt burden continues to rise and structural reforms remain postponed until after the presidential election — a costly status quo, even without a new brutal deterioration. ↓ Rather unfavorable for France.
Degraded
50%
Fairly likely
No-confidence brings down the government, or blocks the budget
The government presents a budget too difficult for part of the opposition to accept. A no-confidence motion this time gathers the necessary 289 votes, or Lecornu abandons his text for lack of sufficient support. The government falls, or the budget timeline becomes impossible to follow normally: a special law then becomes necessary to allow the state to continue functioning.
This scenario becomes the most likely of the three for the first time since July 29 (30% → 50%), not because a fall is certain, but because the political room for maneuver has shrunk faster than the budgetary constraint itself. It remains more likely than a compromise, which is out of reach with such a minimalist budget, and is now also more likely than a simple Article 49.3, because the PS has less and less to lose by voting for no-confidence just months before a presidential election where it must distinguish itself.
Indicators affected
Taux d'emprunt à 10 ans (OAT)au-delà de 4,5 %, durablement↑(vs ≈4,44 % actuellement)
Déficit visé pour 20275,5 % ou plus, net dérapage↑(vs objectif officiel de 4,9 %)
The France angleA budget crisis would not mean bankruptcy: the state would continue to function, via a special law if necessary. But it would likely cause a lasting increase in the French risk premium and complicate debt financing, right in the middle of the presidential campaign. ↓ Rather unfavorable for France.

Key takeaways
Un an après avoir dû recourir au 49.3 pour faire passer son budget 2026, Sébastien Lecornu peut-il éviter un nouvel épisode aussi périlleux avec le budget 2027 ?
Depuis notre première évaluation du 29 juillet, l'Insee et le gouvernement ont abaissé leur prévision de croissance pour 2026 à 0,4-0,5 %, et l'objectif de déficit de 5 % du PIB pour 2026 est désormais reconnu hors d'atteinte.
L'issue la plus probable désormais (50 %) : la bataille budgétaire tourne à la crise politique, avec une chute du gouvernement ou un budget si bloqué qu'une loi spéciale devient nécessaire.
Signal à surveiller : la présentation du projet de budget 2027 en Conseil des ministres, le 30 septembre 2026, et la réaction immédiate du Parti socialiste à son contenu.
Très négatif
Notre évaluation de l'impact pour la France : très négatif. Les scénarios où le gouvernement se maintient sous tension via un 49.3 (40 %) ou tombe dans la crise (50 %), soit 90 % de probabilité cumulée, prolongent ou aggravent tous deux un coût déjà là — hausse de la charge de la dette, réformes bloquées — que seul le compromis (10 %) permettrait vraiment d'alléger.
Finance Bill: the state budget submitted to Parliament each fall — outlining planned spending and revenue for the following year.
Article 49.3
A constitutional tool allowing the government to adopt a law without a vote by deputies — but which immediately exposes it to a motion of no confidence.
Motion of no confidence
A vote by which deputies can overthrow the government; an absolute majority (289 votes) is required for it to succeed.
Public deficit
The difference between what the state and public administrations spend and what they earn over a year, relative to the wealth produced (GDP); it is covered by borrowing.
OAT
Obligation assimilable du Trésor: the debt instrument France sells to investors to finance itself. Its rate is the cost of borrowing.
Special law
An emergency text authorizing the state to continue collecting taxes and functioning when no budget has been voted on time.
