LE DÉLUGE ON THE BRINK OF A FRENCH FISCAL CRISIS?

France’s fiscal and political trajectory is likely to push French government bond spreads wider before selective long-term buying opportunities emerge.

• The 10-year French-German spread reached 128 basis points on 1 October 2026, its widest level since the 2012 eurozone sovereign crisis.
• French inflation rose to 3.4% year on year in September from 2.6% in August, while the government expects this year’s deficit to remain at 5.4% of GDP.
• Japanese government bonds have become more attractive to Japanese investors, potentially weakening a historically supportive investor base for French government debt.
• Polls show Marine Le Pen leading the first round of the April 2027 presidential election; a possible Le Pen-Mélenchon second round is estimated at 68%-32%, while Le Pen’s support against Édouard Philippe rose from 51% in July to 57% in September.
• France’s debt-to-GDP ratio has risen to 118% from 86% in 2011, while its rating has declined to Aa3/A+ from Aaa/AAA; Italian and Spanish spreads that were near 120 basis points in 2010 later widened to 550 and 640 basis points respectively.

Takeaway: Insight expects the crisis to deepen while default risk remains very low, so active portfolios should remain cautious until a centrist resurgence, credible fiscal action under Le Pen, or EU intervention changes the outlook; long-term investors may add French debt progressively at wider spreads.
