France’s public debt has risen sharply, from around 65% of GDP in 2007 to over 115% during the COVID-19 crisis. After declining to 110% in 2023, it is rising again and could reach 200% of GDP by 2050 without policy adjustment. Borrowing costs have also increased, with the 10-year government bond yield rising above 4.5% and the spread over German bonds reaching its widest level since 2012. Public debt interest expenditure, at 2.2% of GDP in 2025, could approach 5% by 2050 — almost equivalent to today’s education budget. Rising debt and borrowing costs are narrowing fiscal space, weighing on investment and growth, and making public finances increasingly difficult to stabilise.
