MS Sunday Start Is the Market Sowing Its Wild OATs

French 30-year OAT spreads over Bunds have widened past 150 bps amid persistent fiscal targets slippage and political uncertainty ahead of elections. The ECB is unlikely to intervene directly via the TPI in the near term because the market repricing is driven by fundamentals.

Rising interest rates across OECD economies are being exacerbated in France by fiscal deficits and political uncertainty, pushing the 30-year OAT-Bund spread past 150 bps—surpassing euro debt crisis peaks. Morgan Stanley projects France's 2027 deficit to remain at 5.4% of GDP versus the official 5.0% target, noting that stabilizing debt requires a massive 5 percentage point fiscal turnaround. Because the widening reflects fundamental fiscal arithmetic rather than market dysfunction, the ECB faces a high bar for direct intervention such as invoking the TPI, though it could consider pausing QT or tilting reinvestments if contagion spreads to Italian BTPs.

Key takeaways from the latest edition

• 1.French sovereign bond (OAT) spreads versus Bunds have widened beyond 150 bps, surpassing peak levels from the euro area debt crisis a decade ago due to fiscal slippage and political uncertainty.
• 2.The ECB is unlikely to step in immediately with market interventions such as the Transmission Protection Instrument (TPI), as officials consider the spread widening justified by fundamentals.
• 3.French fiscal debt stabilization would require an estimated 5 percentage point turnaround to reach a primary surplus of approximately 2% of GDP, an adjustment larger than Italy's in the early 2010s.
