Public debt climbs to 119% of GDP; spread over German Bunds hits widest level since 2011. Rising borrowing costs and softening auction demand underscore the critical need for credible fiscal consolidation.
French government bond yields retreated on the back of a broader rally in European fixed-income markets, yet deep-seated concerns regarding the country’s fiscal soundness persist. As debt loads swell and the cost of issuing sovereign debt climbs, the focus has shifted sharply to the government's ability to implement its proposed deficit-reduction plans.
On the 6th (local time), the yield on the French 10-year government bond fell by 14 basis points (1bp=0.01%p) during trading to close at 4.72%. The decline in yields, which reflects rising bond prices, mirrored a general rally across the European sovereign debt market.
Marine Le Pen, leader of the far-right National Rally party, announced plans on the same day to achieve a net fiscal saving of 140 billion euros by 2032 relative to 2026, should she win the next presidential election. Market participants noted that this pledge contributed, at least in part, to the downward pressure on yields, according to Reuters.
Widening spread over Germany signals fiscal warning
A single day’s decline in yields is insufficient to dismiss concerns over fiscal stability. The market’s underlying anxiety has been most evident in the widening spread between French and German government bonds.
Data from an EFG International analysis on the 5th indicated that the yield gap between 10-year French and German bonds widened to over 150 basis points on the 2nd—the highest level since late 2011. Concurrently, the French 10-year yield flirted with the 5% threshold, a high not seen since 2002.
The widening spread reflects that investors are demanding a higher risk premium to lend to France, despite the country sharing the same euro currency as Germany. EFG pointed to concerns over the sustainability of French public finances and heightened political uncertainty as the primary drivers of this divergence.
Surging debt and the burden of rising borrowing costs
According to the National Institute of Statistics and Economic Studies (INSEE), France's public debt reached 3.5955 trillion euros at the end of the second quarter of this year. This represents an increase of 59.6 billion euros from the previous quarter, pushing the debt-to-GDP ratio from 117.5% to 119.0%.
Higher market rates have begun to reflect in the actual cost of sovereign issuance. In an auction held by Agence France Trésor (AFT) on October 1, the average yield for bonds maturing in November 2036 was 4.93%, a significant jump from the 4.23% recorded in the previous auction on September 3.
The impact of rising rates is cumulative, particularly as the state reissues debt to fund new borrowing and roll over maturing obligations. Replacing low-interest debt with more expensive instruments elevates interest expenditures, making fiscal consolidation more difficult and increasing the burden of future borrowing.
Auction demand has also shown signs of cooling. The bid-to-cover ratio—the total value of bids received divided by the amount of debt sold—fell from 2.28 to 2.00 over the same period, indicating that demand relative to the volume of issuance is weakening.
Deficit reduction vs. rising debt: The political bottleneck
In its 2027 budget proposal unveiled on the 1st, the French government set a target to reduce the fiscal deficit from an estimated 5.4% of GDP this year to 5.0% next year. The plan entails 54 billion euros in fiscal improvements, including spending caps and tax adjustments, with 43 billion euros coming from new measures.
However, the government itself projects that even with these measures, the public debt-to-GDP ratio will climb to 121.7% by 2027. This suggests that the debt ratio will continue to trend upward even if the deficit is narrowed.
Political conditions for executing these policies remain precarious. With the 2027 presidential election looming, the government faces significant hurdles in building consensus within a fractured parliament. The proposed budget must survive intense political opposition, and Le Pen's austerity pledges will likewise require credible execution mechanisms to be taken seriously by the markets.
The key indicators to watch moving forward are the extent to which deficit reduction targets—and the measures to achieve them—remain intact during the budget deliberation process. Investors will also be closely monitoring whether yields and auction demand stabilize in upcoming sovereign bond offerings.
