French government borrowing costs have climbed near five percent, widening yield spreads over Germany and stirring wider fears of financial contagion across Europe.
France Bond Yields Hit Multi-Decade Highs
The yield on France’s benchmark 10-year government note, known as an OAT, touched 4.96 per cent last week, marking its highest level since July 2002. As investors demand a larger premium to hold French sovereign debt, the widening spread between French and German borrowing costs has expanded to about 130 to 140 basis points, levels not consistently witnessed since the eurozone debt crisis of 2012.
Stephen Coltman, head of macro at digital asset firm 21shares, noted that five years ago French 10-year borrowing rates were effectively zero before fast approaching 5%. Deutsche Bank noted that the French-German spread recorded its largest weekly rise since 1990, while Mohamed El-Erian wrote that contagion risk has returned to Europe.
France’s debt mountain stands at 119 per cent of its GDP.
The European Commission estimated that the policy status quo would push France’s debt-servicing costs to €124 billion in 2030, which is sixty per cent more than its defense budget.
Political Gridlock Threatens the 2027 Budget
Emmanuel Moulin, the governor of the French central bank, argued in an interview that France must remain master of its own destiny and called on politicians to pass a budget this year to reassure markets. If we don’t act, there is indeed a risk of being gradually strangled by rising interest rates,
Moulin warned.
Bundesbank Nagel added that while uncertainty calls for flexibility, that does not mean it calls for inaction. Far-right presidential candidate Marine Le Pen pledged significant spending cuts to get debt under control, warning that France ultimately risks defaulting on its obligations.
Central Bankers Weigh Potential Intervention Measures
UBS CEO Sergio Ermotti told CNBC that hard measures
are needed to tackle the crisis, warning that incremental changes will not suffice to restore a credible path to growth. Ermotti compared the current turbulence to the 2011 eurozone debt crisis.
As borrowing costs rise, attention has turned to whether the European Central Bank might step in to calm the market. While the ECB’s Transmission Protection Instrument exists to counter unwarranted market fragmentation, deploying it requires strict fiscal discipline that remains politically elusive ahead of upcoming electoral contests. ING global head of macro research Carsten Brzeski argued that the ECB could temporarily pause quantitative tightening and reinvest maturing bonds flexibly to send a positive signal to bond markets. Former ECB board member Lorenzo Bini Smaghi similarly called on the central bank to put quantitative tightening on hold to relieve upward pressure on long-term bond yields.
Agence France Trésor Plans Record Bond Issuance
Agence France Trésor plans to issue a record €340 billion in medium- and long-term government bonds in 2027, up from €310 billion this year. Much of this issuance replaces maturing pandemic and energy-crisis debt rather than creating fresh liabilities, and recent auctions have demonstrated that buyers remain active. France competitively allotted €11.999 billion across four long-dated OAT lines from €27.487 billion of bids, achieving an aggregate competitive bid-to-cover of about 2.29 times. Weighted average yields at the auction were recorded at 4.93% on the 2036 line, 4.97% on the 2037 line, 5.06% on the 2038 line, and 5.40% on the 2048 line.
Sumitomo Mitsui DS Asset Management, one of Japan’s largest asset managers, liquidated its entire holdings of French debt. Japanese investors held about $145 billion of French bonds in July, representing roughly 4% of France’s marketable government debt and 6.6% of Japan’s overseas bond holdings, but higher hedging costs and rising domestic alternatives have accelerated reductions in foreign holdings.
Market strategists warn that the ongoing sell-off carries consequences for European equities, banking sectors, and the euro. With yields in France now exceeding those of Italy and Greece, analysts continue to monitor whether fixed-income stress will spread further across the currency bloc ahead of upcoming electoral contests.
