France leads the rise in yields
Presenting its European debt-market review in London on Wednesday, Fitch reported that France's benchmark 10-year government bond yield rose 141 basis points in the year through the end of October. Belgium's increase was 103 basis points, followed by Italy's at 98 and the United Kingdom's at 82.
The French 10-year yield reached 4.9% at the end of October, compared with 4.1% when Fitch reviewed the country's rating in August. Its spread over comparable German Bunds briefly hit 174 basis points. According to Fitch, that extra return demanded by investors for holding French rather than German debt was comparable to levels during the eurozone debt crisis.
France and Italy face the greatest exposure
Fitch identified France and Italy as the EU sovereign borrowers most sensitive to higher yields, citing projected year-end 2026 public debt of 119% of GDP for France and 138% for Italy.
In the agency's estimates, a 1-percentage-point rise in yields would add the equivalent of 0.2% of GDP to interest costs in each country in the first year and 0.3% in the second. Its model for Hungary shows smaller increases from the same yield change: 0.1% of GDP in the first year and 0.2% in the second.
Long average debt maturities offer highly indebted European countries some protection from higher borrowing costs. Nevertheless, Fitch said average debt-servicing expenses are increasing, making budget deficits harder to bring down.
France's fiscal outlook weakens
On October 30, 2026, Fitch changed the outlook on France's A+ sovereign rating from stable to negative, indicating a greater risk of a downgrade. The unscheduled, out-of-cycle action reflected what the agency described as a material deterioration in France's credit profile since its August 2026 evaluation.
That review projected French general government debt would climb from 115.7% of GDP in 2025 to roughly 124% in 2028. Fitch estimated that stabilizing debt would take a cumulative fiscal adjustment equivalent to about 3.5% of GDP.
Fitch expects France's budget deficit to remain at 5.5% of GDP, rather than the 5.0% sought in the draft 2027 budget. It cited weaker economic activity and legislative concessions for the gap between its forecast and the government's target. The agency also forecast sovereign interest payments of 3.3% of GDP by 2028.
Its reduced growth forecasts put France's expansion at 0.5% in 2026 and 0.9% in 2027. Fitch warned that street protests and limited room for fiscal maneuver pose additional downside risks ahead of the 2027 election cycle.
Stronger safeguards, but risks remain
Despite the similarity in French-German yield spreads, Fitch said conditions differ in important respects from the early-2010s crisis. It sees no signs of overheating in the most vulnerable markets, while stronger banking safeguards help contain risks associated with banks' close ties to their home countries' sovereign debt markets.
Europe also has a broader set of tools to manage systemic financial stress than it had during the earlier crisis. Fitch said these differences reduce risks both to individual sovereign borrowers and to eurozone stability.
The agency nevertheless warned that investors could abruptly demand much higher yields from governments they consider to be making too little progress toward sustainable public finances. Such a jump could destabilize those countries' wider economies.
