France's Risk Premium Spikes to Euro-Crisis Levels: 10-Year Bond Yield Hits 5% for the First Time Since 2002

On October 1, 2026, the yield on France's 10-year government bond (OAT) hit an intraday high of 4.99%, the highest level since July 2002, while the risk premium over German Bunds briefly topped 147 basis points, its widest since the 2011-2012 eurozone debt crisis. The trigger was the same-day presentation of Prime Minister Sébastien Lecornu's 2027 budget bill — but the move is the culmination of more than a year of political instability in the eurozone's second-largest economy.

Context: a year without a majority — or a stable budget

France has been governing without a clear parliamentary majority since the National Assembly was dissolved in 2024. The country spent much of 2025 without a budget in force — reportedly up to six months, according to several contemporaneous accounts — and saw Michel Barnier's government fall in late 2024 and François Bayrou's in September 2025. Sébastien Lecornu was appointed prime minister on September 10, 2025; he resigned just 27 days later, on October 6, 2025 — the shortest tenure of the Fifth Republic — after his own cabinet lineup triggered an immediate backlash in the Assembly. He returned to Matignon days later with a second government, the one still in place today.

That turmoil shows up clearly in debt markets. The average OAT 10-year yield rose from 3.40% in February 2026 to a monthly average of 4.00% in August — the highest monthly average since October 2008 — and by mid-September it was already trading around 4.50% in the sessions of September 15 and 16. The spread over Germany followed the same path: from roughly 90 basis points in mid-September to 124 basis points on September 30, right before the budget was unveiled.

The verified data point: October 1's 4.99% and the 2011-2012 echo

On Thursday, October 1, 2026, Lecornu presented the 2027 budget bill (the Finance Bill and the Social Security Financing Bill) to the Council of Ministers. The plan combines €43 billion in new measures with previously announced steps, for a total consolidation effort of €54 billion, with the stated goal of cutting the deficit from an estimated 5.4% of GDP in 2026 to 5.0% in 2027. France's public debt is on track to exceed 120% of GDP next year, and Agence France Trésor is planning a record issuance programme of around €340 billion for 2027. The independent fiscal watchdog (Haut Conseil des finances publiques) called the macroeconomic assumptions behind the plan "optimistic."

The bond market's reaction was immediate: the 10-year OAT touched an intraday high of 4.989% that same Thursday — the highest level since July 2002 — before easing slightly to around 4.91% the next day. The spread over German Bunds briefly hit 131 basis points on the day the budget was unveiled (a 14-year high) and kept widening over the following days to somewhere between 145 and 152 basis points between October 1 and 5, depending on the data provider — the widest level since the 2011-2012 euro crisis. By October 6, as the broader global bond selloff eased and oil prices pulled back, the OAT fell to 4.75% and the spread narrowed to around 129 basis points — a reprieve, not necessarily the end of the episode.

The Paris stock market moved in lockstep: the CAC 40 fell 1.6% on October 1 to 7,835 points, its lowest level since late March, dragged down mainly by banks and luxury names — BNP Paribas dropped 3.6%, LVMH 2.7% and Airbus 2.6% that session — before rebounding 0.4% on October 6. The euro, for its part, weakened to $1.1161 on October 5, its lowest level since May 2025 and its fourth consecutive weekly decline against the dollar.

Analysis by sector and asset class

French banks (Société Générale, BNP Paribas, Crédit Agricole). They are the most direct transmission channel: their balance sheets are loaded with French sovereign debt, their wholesale funding costs rise in tandem with the government's, and their share prices have historically been the fastest thermometer for any French fiscal-stress episode — hence BNP Paribas's drop of more than 3% on budget-presentation day.

European fixed income and the periphery. Contagion risk to Spain and Italy exists, but for now the market is treating this as a French idiosyncratic episode — its spread over Bunds has widened far faster than that of southern European countries, which at some points in 2025 were even trading tighter than France. That suggests investors are distinguishing French political risk (no majority, no stable budget) from Italian or Spanish fiscal risk, neither of which is going through an equivalent governability crisis right now.

Currencies. The euro suffers because a higher sovereign risk premium in the eurozone's second-largest debt issuer erodes aggregate confidence in the bloc, even if the German Bund itself doesn't move. An ECB that can't — or won't — intervene adds further pressure on the currency.

French cyclicals and luxury names. LVMH and peers trade with a "country brand" premium that suffers when political instability dominates headlines, on top of these companies' direct exposure to discretionary spending, which a €54 billion fiscal adjustment (via taxes, spending cuts, or both) could depress in the domestic market.

Global sovereign debt. AFT's planned record issuance for 2027 (roughly €340 billion) competes for demand with the rest of Europe's sovereign issuers at a moment when yields are already elevated globally — an additional source of pressure on long-dated rates across the eurozone, not just in France.

Historical parallel: is this 2011 all over again?

The comparison with the 2011-2012 eurozone debt crisis is the one everyone is making, and it isn't frivolous: in November 2011, at the peak of that crisis, France's risk premium over Germany reached 164 basis points. This week's peak (somewhere around 147-152 basis points, depending on the source) falls short of that record, but it has already surpassed the 86 basis points the spread hit in October 2025, when Lecornu's first government resigned — which was already seen as a warning sign at the time.

There is one important structural difference from 2011: back then, the market doubted the solvency of the euro project itself and demanded risk premiums from several southern European countries simultaneously, with the ECB initially absent as a lender of last resort. Today the ECB has an explicit anti-fragmentation tool (the Transmission Protection Instrument, created in 2022) — but, crucially, a former ECB official quoted in specialist press this week warned that "the ECB would be hard-pressed to justify intervention when the root cause is domestic fiscal policy" in a single country, rather than a broader breakdown in the monetary-policy transmission mechanism. In other words: the institutional backstop that prevented a collapse in 2012 is not guaranteed for a problem the market itself reads as self-inflicted by French political paralysis, rather than a plumbing failure of the euro itself.

What to watch next

• October 13, 2026: the National Assembly opens its plenary debate on the 2027 budget, with more than 1,700 amendments filed. It's the first real test of whether the text survives without a no-confidence vote.
• Censure threat: Jean-Luc Mélenchon (LFI) has already announced his party will vote to censure the government over this budget; the positions of the National Rally (RN) and the Republicans will be decisive for Lecornu's survival.
• October 29, 2026: the ECB's Governing Council meets — any comment on France, even indirect, will move the spread.
• Agence France Trésor auctions: the bid-to-cover ratio on upcoming OAT issuance will be the most objective test of whether institutional demand still holds at these yield levels, ahead of the record 2027 issuance programme.
• The 2027 presidential campaign: every instability episode from here on will be read through an electoral lens, which will likely keep the political risk premium structurally higher than in the recent past, with or without a fresh market scare.

For investors exposed to European fixed income, French banks, or the euro, the question is no longer whether France has a fiscal problem — that has been priced in gradually since 2024 — but whether October 13 marks the start of a political resolution (even a partial one) or a new escalation toward snap legislative elections that the market has not yet fully priced in.
