On October 1, the day the government presented a €54 billion savings plan for 2027, the yield on France’s ten-year bond reached 4.96 percent, the highest since 2002. The premium over German Bunds stood at about 130 basis points that day and widened further on October 2, to more than 150, the highest since late 2011.
Two weeks earlier, the headline had been smaller and stranger. In mid-September France paid about 4.50 percent for ten years and Greece about 4.28. The two had briefly converged once before, in November 2024, at about 3 percent. This time Paris was clearly above Athens, and a country that needed three bailouts was borrowing more cheaply than the euro’s second-largest economy.
Greece has earned part of that. Its 2025 budget closed with a surplus of 1.7 percent of GDP, France’s with a deficit of 5.1. Greece’s debt ratio stood at 143.5 percent in the first quarter of 2026, down more than nine points in a year, and the Commission expects 134 percent in 2027. France’s was 117.6 percent, and the Commission sees it above 120 in 2027. But the comparison flatters Athens as well. Its debt has an average maturity of more than 18 years, mostly at fixed rates, much of it bailout-era loans on concessional terms. Athens plans about €8 billion of market issuance this year against roughly €310 billion of net medium- and long-term issuance for France. Fitch and S&P still rate France at A+, Greece at BBB. Investors are not declaring Athens safer than Paris. They are telling Paris that a deficit of that size cannot be financed on faith.

The deficit is a political product. Since Emmanuel Macron dissolved parliament in 2024, France has been run by Gabriel Attal as caretaker, then Michel Barnier, François Bayrou and now Sébastien Lecornu. Barnier and Bayrou both fell over the budget. Lecornu got the 2026 budget through on February 2 under Article 49.3, without a vote, and survived two no-confidence motions only because the Socialists declined to join them. In exchange, the Socialists won a suspension of the rise in the retirement age, from 62 to 64, until 2028, which puts the reform on hold through the 2027 presidential election.
Next year’s budget meets the same arithmetic in a parliament with no majority for it. Paris has no trouble servicing its debt today. Its trouble is agreeing on how to stop the debt from growing, while debt-servicing costs are projected to approach €100 billion a year by 2029.

This is where the comparison with Greece stops being useful. The European Central Bank’s most explicit instrument against a disorderly rise in Italian or Spanish yields is the Transmission Protection Instrument, introduced in 2022, which lets it buy a country’s bonds before panic takes hold. TPI comes with several conditions, among them compliance with the EU fiscal framework, which for a country under an excessive deficit procedure means not having been found to have failed to take effective action, and a judgment that its debt is sustainable. France has been under such a procedure since July 2024. Whether it would pass those tests is a question nobody has had to answer, because TPI has never been used.
The ECB’s own behavior sharpens this. On September 10 it raised its deposit rate to 2.50 percent, citing inflation pressure from the energy shock of the Middle East conflict and a projected 3.0 percent for this year. In April I argued here that Frankfurt sets rates at the level Rome, Madrid and Paris can bear. That ceiling concerned the level of rates, and 2.50 percent is nowhere near it. What France is testing is the spread, and the spread is what TPI exists to manage.
The firewall built after Greece rested on an assumption: that instability starts at the periphery, in an economy small enough for the center to absorb. France accounts for about a fifth of euro-area GDP. The ECB’s rules are flexible enough that critics have long called the conditions a fig leaf, and if Paris needed help, Frankfurt would almost certainly find a way. But a rescue by improvisation is something markets price like any other risk, and outside the Governing Council nobody can say what the terms would be.

The strongest objection deserves a straight answer. A spread of 150 basis points is still well below the 225 reached in November 2011, no auction has failed, and part of the move is a global bond selloff. All true. A selloff lifts Bunds as well, however, and cannot explain a widening against the Bund itself. And the absence of a failed auction is no comfort. TPI is meant to counter disorderly market dynamics, and what counts as disorderly is a judgment the Governing Council makes alone.
THE VERDICT
The harder problem is timing. TPI eligibility turns in part on a judgment about whether a government is correcting its deficit, and if the test came for France, it would plausibly fall in the months before the April 2027 presidential election, in a race led in first-round polls by Marine Le Pen, who has pledged to return the retirement age to 62, and to 60 for some workers who started early. Finding Paris compliant means endorsing a budget its next president may promise to unwind. Finding it non-compliant means intervening in a French election. The same Governing Council would be making that call while it tightens policy against an energy-driven inflation shock.
The backstop was built for countries whose elections Frankfurt could afford to ignore. France is the first where it cannot.
