France’s Debt Bill Squeezes Paris

France’s 10-year government bond yield — the return investors demand to hold French debt at today’s market price — reached 4.05% last week, its highest level since 2009 (Boursorama/Reuters, LSE). For Maltese readers used to watching EU fiscal rules from the perspective of a small eurozone state, the point is not that France is suddenly shut out of markets. It is that borrowing has become more expensive, and that cost enters the budget slowly as old, cheaper debt matures and is replaced with new debt issued at today’s rates.

France is not being singled out by markets in isolation. Long-term borrowing costs have also risen in Germany, Japan, the US and the UK (The Guardian). The France-specific signal is the spread with Germany: the gap between what Paris and Berlin pay to borrow. Last week it stood at 84–86 basis points, or 0.84–0.86 percentage points (Boursorama/Reuters, QuiFinanza). Italy’s spread was around 78–82bp (El Economista). France now pays more than the country that defined the eurozone debt crisis a decade ago.

How 4% Slowly Eats the Budget

France carries €3,536 billion in public debt (INSEE). That stock does not reset overnight. Bonds already issued keep paying their original, lower rates until maturity. The pressure comes through refinancing: when old bonds expire, France’s debt agency, the AFT, must replace them at current market rates. This year it plans to issue about €310 billion in medium- and long-term bonds, up from under €210 billion in 2019 (Le Figaro, AFT).

The effect is already visible in the accounts. France’s interest bill reached €34.5 billion in the first half of 2026, 19% higher than in the same period last year (Reuters Breakingviews). Government estimates put the full-year cost at €64.8 billion in 2026 and €74.2 billion in 2027, compared with €31.6 billion in 2019 (Le Figaro). Every extra euro spent on interest is a euro that cannot go to services, tax cuts or deficit reduction.

Who Pays, Who Collects

New buyers of French bonds receive better income than they did when France could borrow at 1% or 2%. Insurers, pension funds and savers looking for yield benefit from the higher coupon. Existing bondholders face the opposite effect: as yields rise, the market price of older bonds with lower coupons falls (Notizie.it). Those losses remain on paper unless the bonds are sold, but banks and funds that mark portfolios to market have to reflect the hit on their balance sheets (Il Messaggero).

The clearest losers are future French taxpayers and people who depend on public services. The IMF says France needs structural budget tightening of about 0.8% of GDP per year through 2029 to stabilise its debt (IMF). Structural tightening means permanent measures, not one-off accounting fixes. Prime Minister Sébastien Lecornu is aiming for a 2027 deficit of around 4.9% of GDP, while the EU path requires something closer to 4.3% (Le Monde). Closing that gap means spending freezes, tax rises, or both.

Rome and Athens gain a useful political line from the comparison. Italian fact-checkers note, however, that the picture flatters Italy partly because German yields have risen sharply too, not only because Italy’s fiscal position has improved (Pagella Politica).

France Can Still Borrow. The Budget Is the Problem.

On 20 August, the AFT sold €12.5 billion in bonds, with demand comfortably above supply (Les Echos Investir). Investors are still willing to lend to France. They are simply charging more for doing so.

The ECB has a bond-buying instrument, the Transmission Protection Instrument, designed to counter unjustified market pressure on a eurozone country’s debt. But access depends on the country broadly respecting EU fiscal rules. France has been under the EU’s excessive-deficit procedure since July 2024 — the corrective process used when a member state’s deficit breaches the bloc’s limits — which makes ECB intervention harder to defend (ECB, European Commission).

France can still sell bonds. The harder test is political: Paris has to legislate several consecutive years of budget tightening before the 2027 presidential election makes fiscal discipline even less attractive.
