Key Facts

1The French-German bond yield spread fell 14 basis points to 154 basis points on October 26, 2026.
2Fitch forecast that debt would rise to 124% of GDP in 2028, from 115.7% in 2025.
3French GDP contracted 0.1% in the third quarter of 2026, after zero growth in the second quarter.
4Moody’s affirmed France’s rating at Aa3 with a negative outlook on October 23, 2026.

The yield spread between French and German 10-year bonds fell 14 basis points to 154 basis points on Monday, October 26, marking its largest daily decline on a closing basis since the 2020 pandemic, according to Bloomberg via The Star. The move followed a rally in French bonds after the country avoided a Moody’s downgrade that the market had expected. Moody’s affirmed France’s rating at Aa3 with a negative outlook on October 23. But market relief at the agency’s decision did not end concerns about public finances. Fitch changed its outlook to negative days later while affirming the rating at A+, citing pressure from growth, borrowing, the deficit and political divisions.

The spread’s decline was accompanied by a fall in the yield on France’s 10-year bond, which dropped 6 basis points to 4.963% on October 26, according to Reuters via Fidelity. The yield had risen to 5.1415% on Thursday, October 22, its highest level since June 2002. That trajectory puts Monday’s rebound in the context of an earlier sell-off that pushed French borrowing costs to their highest levels in more than two decades. The yield’s movement differs from the spread between French and German bonds: the former measures France’s financing cost, while the latter reflects the premium investors demand over German debt. Both measures fell on Monday, alongside market relief at Moody’s decision.

Fitch said it had changed its outlook from stable to negative and affirmed the rating at A+, citing weak growth, higher borrowing costs, a widening deficit and political divisions, according to Reuters. The agency forecast that the debt-to-GDP ratio would rise to about 124% in 2028, from 115.7% in 2025. That trajectory means the debt burden is likely to continue rising in the coming years, while borrowing costs make it harder to contain the deficit. Fitch also cited the size and diversity of the French economy, the strength of its institutions and its euro zone membership as factors supporting the rating. The contrasting assessments highlight a difference in timing: the market welcomed France avoiding a Moody’s downgrade, while Fitch linked its negative outlook to deteriorating debt dynamics and fiscal and political risks.

Moody’s assumes that a budget will be adopted to reduce the deficit in 2027, alongside some easing in financing costs and social tensions in the coming months, according to its statement as reported by Reuters via Investing.com. The agency affirmed France’s rating at Aa3 with a negative outlook, making the upcoming budget part of the assumptions underpinning its credit assessment. This comes as preliminary data showed French GDP contracted 0.1% in the third quarter of 2026, after standing at 0.0% in the second quarter, according to France’s statistics institute INSEE. The contraction adds to the economic picture informing concerns about the government’s ability to reduce the deficit. The French inflation data in the first draft also required a distinction between the preliminary October estimate and the final September reading; the verified facts used here include no figure that can be included in this context.

INSEE set November 5, 2026, as the date for publishing French industrial production data for August. The institute is scheduled to release its next GDP reading on November 27, 2026, for the third quarter of the year. These dates follow the contraction in the preliminary third-quarter GDP reading and will add data to the monitoring of the French economy’s performance. Investors are also watching the budget path that Moody’s assumes will be adopted to reduce the deficit in 2027, amid Fitch’s forecast of a rising debt-to-GDP ratio. The movement in the French-German bond spread, which fell to 154 basis points on Monday, remains a direct indicator of changes in the premium investors demand on French debt.
