French 10-year bond yields surpass 4.9% as public debt reaches €3.6 trillion

Surge in French bond yields and debt stock

French ten-year sovereign bond yields have climbed above 4.90%, up from below 3% recorded two years ago, following the government's presentation of the 2027 draft budget. Data from the French National Institute of Statistics and Economic Studies (INSEE) shows that French public debt reached 3,595.5 billion euros at the end of the second quarter of 2026. This total represents 119% of gross domestic product, with the government projecting the debt ratio to reach 121.7% in 2027. France owes this sum to a broad base of institutional creditors, including banks, insurance corporations, and pension funds. INSEE and the Banque de France forecast nearly flat economic activity, which limits tax revenue growth while the Assemblée Nationale prepares to debate the 2027 budget proposal.

Market volatility and international exposure

Financial markets showed limited enthusiasm for the fiscal measures outlined in the budget bill. Volatility in French sovereign bonds has also affected the broader euro zone, contributing to declines in the value of the euro over several consecutive trading sessions. Christopher Dembik, investment strategy adviser at Pictet AM, characterized the prevailing market sentiment toward the government's proposals.

Investors were not convinced by the budget draft presented last week by the government.

International portfolio allocations present additional risks to French debt stability. A Bloomberg analysis estimates that Japanese investors held 23 trillion yen, equivalent to 145 billion dollars, in French sovereign bonds as of July 2026. This position substantially exceeds recommended benchmark weights, creating potential exposure if Japanese institutions choose to reallocate capital. Concurrently, global hedge funds, which manage an estimated 11.3 trillion dollars in total assets, have increased their scrutiny of French state liabilities.

Growing interest expenses on sovereign debt

The persistent rise in borrowing rates is translating directly into higher debt servicing costs across the coming years. According to projections from research institute Rexecode, the average interest rate on France's debt stock will reach 2.2% this year, climbing to 2.5% in 2027 and 3.2% in 2030. These escalating obligations will absorb an expanding share of state resources.

Economist Jean Pisani-Ferry emphasized that market participants prioritize structural fiscal discipline over indiscriminate budget reductions as lawmakers begin deliberations.

Markets want fiscal responsibility, not austerity.

Global borrowing reaches 365 trillion dollars

France's budgetary challenges reflect a wider international trend of expanding debt despite the absence of an economic recession. A report from the Institute of International Finance shows that total global debt across public and private sectors reached 365 trillion dollars in the middle of 2026. Global liabilities expanded by 10 trillion dollars during the first six months of the year. Although the global debt-to-GDP ratio fell by 25 percentage points from its 2021 peak to 310% of world GDP, the IIF noted that this decrease was largely an accounting effect caused by elevated inflation inflating nominal GDP rather than real fiscal consolidation. Continued inflation has compelled central banks to maintain higher interest rates, raising financing costs for sovereign states and private borrowers worldwide.
