Act I • The debt market
The surge in the French 10-year and the uncontrollable spiral of the debt burden
The silence of the trading floors no longer masks the fundamental anomaly. Long sheltered behind the joint signature of the Franco-German axis and the colossal liquidity-injection programmes, French sovereign debt now faces an undertow of unprecedented violence. Auctions of 10-year government bonds (OAT), conducted by the Agence France Trésor (AFT), recently came close to the symbolic and dangerous 5% ceiling, with trades concluded at 4,93%, breaking spectacularly with the 3.2% plateau that had prevailed before.
To grasp how fast this shockwave spreads, the budget equation must be set out in full arithmetic rigour. The state's stock of debt now stands at nearly 3 600 milliards d'euros. With the average maturity of that mountain of borrowing at about eight years, the Treasury must refinance one-eighth of the principal each year, roughly 450 milliards d'euros a year, on top of the current primary deficit.
The mechanics of 10 basis points
In this configuration, every marginal rise of 0,10% (10 basis points) generates a direct additional cost of 3,6 milliards d'euros in extra interest accumulated across the debt stock.
Should borrowing rates settle durably between 4.5% and 5%, the average annual increase in the debt burden will inevitably range between an additional 61 and 180 milliards d'euros by the time the entire liability has rolled over. That crushing burden would absorb all of the nation's fiscal room for manoeuvre, exceeding on its own the combined consolidated budgets of national education and the armed forces.
Reference level: 3.20% in normal conditions. Critical alert threshold estimated at 5.00%.
Average maturity: 8.2 years • Continuous refinancing of one-eighth of the stock each year.
Projected interest overrun in the event of a durable plateau at 5%: +61 Mds € to +180 Mds €.
The scheduled end of the Frankfurt umbrella: the extinction of Quantitative Easing
For more than a decade, the French Treasury benefited from the unprecedented intervention of the European Central Bank (BCE (ECB)), whose balance sheet peaked between 4 000 and 5 000 milliards d'euros thanks to the systematic repurchase of sovereign debt on the secondary market. That protective cushion has disappeared.
Engaged in quantitative tightening (Quantitative Tightening) to curb inflationary pressures and constrained by its founding treaties, the ECB no longer offsets sovereign issuance. From now on, every euro of French paper must win over a full-fledged investor in an unadministered market. France is thus taking the full force of market discipline, raising the historic spectre of a Greek-style scenario: a spiral of distrust, prohibitive interest rates and potential supervision by an international Troika (EU, ECB, IMF), whose past remedies imposed brutal 40% cuts on public pensions and salaries.
Act II • Derivatives & Arbitrage
The verdict of Credit Default Swaps: Paris judged riskier than Rome and Athens
However reassuring the official statements, the derivatives market reveals a merciless reality. Credit Default Swaps (CDS), those financial insurance contracts against a sovereign borrower's default, serve as an infallible thermometer of credit risk.

Caught in the hedge-fund pincer
According to the flows monitored by the research desks of major investment banks such as Bank of America and Deutsche Bank, Anglo-Saxon hedge funds now reportedly take up more than 50% of new French bond issuance. These players have no intention of holding the paper to maturity; they chase the short-term carry trade or arbitrage rating downgrades, amplifying volatility on AFT issuance.
The Scandinavian contrast: an uncomfortable mirror
The Swedish counter-example illustrates the structural gap. With a CDS contained at just 9 basis points, Stockholm runs a balanced budget while guaranteeing a net median wage above 2 800 €, against roughly 2 190 € in France. That differential shows that the scale of France's public deficit guarantees neither the relative prosperity of households nor the solidity of the social contract.
Act III • Institutional gridlock
The budget impasse and the constitutional lock of the special law
On the political front, the National Assembly has become the stage for a systematic quagmire. Without a stable absolute majority to support the government led by Sébastien Lecornu, the macroeconomic assumptions underlying the finance bill have been severely disavowed by financial rating agencies such as Moody's and the economist teams at Barclays. The latter judge the growth and structural-savings forecasts to be out of reach in a context of parliamentary fragmentation.
The legal trap: the ban on legislating by ordinance in the event of a rejection
Contrary to a widespread belief, Article 47 of the Constitution does not allow the government to pass a budget by ordinance if the text is subject to an outright rejection or a successful no-confidence motion. In such a case, the executive is forced to resort urgently to a "special law".
This institutional straitjacket is compounded by a highly charged social atmosphere: protest demonstrations, relayed by secondary-school and union coordinating bodies, heighten the timidity of the legislative machinery. Lawmakers fear endorsing the slightest austerity plan, freezing France in a status quo that is untenable for the world's institutional investors.
Act IV • Constitutional denouement
The thesis of a presidential resignation: Article 7 against the tyranny of urgency
This is where the decisive chronological fracture comes in: "The time of financial speculation is not political time."
While the regular electoral calendar sets the presidential election for spring 2027, the capital markets, for their part, demand decisions within a fortnight. No Treasury can survive for a year and a half with benchmark rates at 5% and a slipping deficit without a clear political line. Faced with the impossibility of dissolving the National Assembly again before the legal one-year deadline, a supreme mechanism is beginning to circulate in constitutional-law circles: the application of Article 7 of the Constitution.
The constitutional sequence of a vacancy of power
Formal resignation of Emmanuel Macron
Acknowledging the ungovernability and the financial asphyxia, the head of state relinquishes his office to send the arbitration decision directly back to the sovereign people.
Constitutional interim at the Palais du Luxembourg
In accordance with paragraph 4 of Article 7, the interim presidency of the Republic immediately falls to the President of the Senate, Gérard Larcher, with circumscribed powers (a formal ban on calling a referendum or dissolving the Assembly during this period).
Organisation of the presidential vote within 20 to 35 days
The Constitutional Council oversees a lightning presidential election. The newly elected president then enjoys full democratic legitimacy to decree at once the immediate dissolution of the National Assembly, clearing the way for a coherent majority able to vote through a budget-adjustment plan.
This rupture scenario, traumatic as it would be for the machinery of state, appears in the eyes of some investment bankers as the only orderly way out. Absent such internal democratic clarification, the alternative would be an unchosen external tutelage: intervention by the European Union and the ECB under figures such as Christine Lagarde, making any emergency repurchase of French debt conditional on social and budgetary concessions imposed from the outside.
Act V • Structural diagnosis
Beyond finance: suffocation by the "bureaucrature"
The bond-market crisis is only the clinical symptom of a deeper ailment affecting the French administrative model. Several observers and grassroots elected officials, in line with the theses developed by Frédéric Masquelier or David Lisnard, highlight the concept of the "bureaucrature".
This proliferation of norms and administration sterilises local economic initiative: a pile-up of state agencies, advisory committees and contradictory regulations that weigh down operating public expenditure while degrading the perceived quality of the public service delivered to citizens. It is this chasm of inefficiency that capital holders are sanctioning today, reluctant to finance at a loss an administrative apparatus that absorbs more than 57% of GDP without restoring balance to the accounts.

The moment of choice between a political denouement and a forced adjustment
France is reaching the crossroads of its constitutional and financial contradictions. Deprived of the unconditional support of the European Central Bank, paralysed by an ungovernable Chamber and under the watchful gaze of the bond markets, the Fifth Republic no longer has the luxury of postponing its deadlines. If the executive refuses clarification by universal suffrage through Article 7, it is the international creditors who will dictate, through the price of money, the scale of the recovery to be achieved.
