French 10Y OAT spreads over Bunds have widened to 85-87bp amid fiscal slippage, rating review scrutiny, and political uncertainty surrounding budget negotiations. While risks may drive spreads to 90-95bp, valuation support near BBB+ levels and structural strengths make wider levels an attractive entry point.

Key Takeaways

  • 1.10Y OAT-Bund spreads have widened aggressively toward 85-87bp driven by summer illiquidity, heavy supply, political risk, and deterioration in fiscal fundamentals.
  • 2.Near-term political hurdles, including contentious 2027 budget negotiations and potential use of Loi Spéciale or Art. 49.3, could push OAT-Bund spreads toward 90-95bp.
  • 3.A spread above 95bp would price OATs in line with BBB+ sovereign ratings, providing valuation support alongside short market positioning, September net redemptions, nuclear energy resilience, and AI infrastructure investments.
