Key points

  • The yield gap between French and German 10-year government bonds has risen above 110 basis points, the widest since the euro-area debt crisis in 2012.
  • France's finance ministry projects public debt at 119.3% of GDP in 2026 and 121.7% in 2027, alongside a 5.4% budget deficit this year.
  • Credit-risk measures and French bank shares are also showing strain, although the European Central Bank retains tools designed to contain disorderly market moves.

France's 10-year borrowing premium over Germany has climbed above 110 basis points, its widest since the euro-area debt crisis in 2012, as investors demand more compensation for holding French government debt. Reuters reported the move on September 25 alongside broader signs of stress in sovereign credit, bank shares and the euro. One basis point equals one-hundredth of a percentage point, so the spread now exceeds 1.10 percentage points.

Debt projections sharpen the focus

The widening spread follows a finance ministry projection that public debt will reach a record 119.3% of gross domestic product in 2026 and 121.7% in 2027, up from 115.7% in 2025. The ministry expects this year's budget deficit to equal 5.4% of GDP. Prime Minister Sebastien Lecornu has proposed a €54 billion savings drive for the 2027 budget, but a divided parliament and cost-of-living pressure leave the timing and final shape of that plan uncertain.

Credit ratings have added another signal. Scope Ratings downgraded France's long-term rating to A+ on September 18 and assigned a stable outlook, citing sustained fiscal deterioration and political constraints. The rating action does not predict default, but it reinforces the market's focus on whether the government can stabilise debt while preserving economic growth. Any further rating changes could affect mandates and risk limits for some institutional investors.

Stress is visible beyond government bonds

The cost of insuring French sovereign debt against default has risen to around 52 basis points for five-year credit default swaps, the highest since April 2017 and roughly double its level six months ago, according to Reuters. French government-bond futures are also being used to express country-specific concerns, although part of their decline reflects a wider global selloff in fixed income rather than France alone.

Equities show a similar divergence. France's CAC 40 was down about 0.5% for 2026 when Reuters compiled the comparison, while the broader STOXX Europe index was up roughly 8%. French banks have faced particular scrutiny because they hold domestic assets and are sensitive to funding costs, economic growth and sovereign-risk perceptions. Credit default swaps for major French lenders have reached their highest levels since April 2025, while the euro has slipped below $1.14 to a three-month low. That does not mean every bank has performed poorly: BNP Paribas had matched the broader European banking index's 19% rise for the year, while Credit Agricole and Societe Generale had gained much less.

What markets are watching next

The European Central Bank's September projections put euro-area growth at 0.9% in 2026 and inflation at 3.0%, a combination that complicates monetary policy across the region. France's weaker domestic outlook and next year's presidential election add country-specific uncertainty. Investors will monitor the 2027 budget, parliamentary support for savings measures, Moody's next rating review and whether the French-German spread continues to widen.

The ECB has instruments intended to counter disorderly fragmentation in euro-area bond markets, but analysts cited by Reuters do not currently expect France to require such intervention. For now, the confirmed development is a repricing rather than a funding crisis: investors are charging France its largest relative premium in 14 years, while credit and equity indicators suggest the concern is spreading across several parts of the financial system.
