France’s Reliance on Foreign Bond Buyers Raises Debt Risks

France faces growing scrutiny over its reliance on foreign bond buyers, with The Wall Street Journal reporting that overseas capital could become a less dependable source of financing. The concern puts investor confidence alongside deficit reduction as a central challenge for the government’s public finances.

Foreign ownership is substantial: non-residents held 55.1% of negotiable state debt in the third quarter of 2025, according to Banque de France data. That measure describes the ownership of outstanding securities, rather than showing whether investors are currently withdrawing money or refusing to buy new bonds.

The distinction matters because a large foreign investor base is not, by itself, evidence of a funding crisis. It does, however, leave France exposed to changes in international demand when it needs to finance budget shortfalls and replace debt reaching maturity.

Official borrowing results also provide a counterweight to concerns about an investor retreat. In its December 2025 bulletin, Agence France Trésor said it had completed the year’s financing programme and that demand remained strong across the range of maturities offered.

The agency issued €347.7 billion of medium- and long-term securities and bought back €47.7 billion, delivering its €300 billion programme net of buybacks. The average maturity of securities issued was 10.6 years, broadly consistent with previous years, according to the bulletin.

Borrowing costs nevertheless showed why the composition of demand matters. The agency reported that average medium- and long-term issuance rates reached 3.14% in 2025, while lower short-term rates helped bring its overall average financing cost down from 3.06% to 2.73%.

France’s underlying fiscal position remains difficult even when bond sales proceed successfully. INSEE’s preliminary figures, published on March 27, 2026, put the 2025 general government deficit at €152.5 billion, equivalent to 5.1% of gross domestic product, compared with 5.8% in 2024.

The smaller annual shortfall did not prevent the debt ratio from rising. The same release put public debt at 115.6% of GDP at the end of 2025, up from a revised 112.6% a year earlier, illustrating the difference between reducing a deficit and stabilising accumulated debt.

For the budget, the risk is that weaker demand would require higher yields on new borrowing. That would feed into financing costs over time as securities mature and are replaced, rather than immediately changing the interest paid on every existing fixed-rate bond.

The next test is therefore not simply whether overseas investors hold a large share of French debt, but whether they continue buying at sustainable borrowing costs. The debt agency’s reported success in completing its 2025 programme shows continued market access; subsequent issuance results and fiscal data will help establish whether that resilience endures.
