France's €59.3 billion interest squeeze

France’s 2026 budget is beginning with a bill that cannot be wished away. Agence France Trésor expects €59.3bn in debt service, the money the state must pay before ministers get near new promises, after Le Monde reported that interest costs rose 37% at the start of the year. By mid-June, the OAT-Bund spread, the gap between French and German government borrowing costs, was around 71-73 basis points. A basis point is one hundredth of a percentage point. Compared with a pre-crisis average of about 53 basis points and a recent 85 basis-point peak cited by OMFIF, France is now paying a clear premium.

Why The Budget Vote Matters

Boursorama’s sovereign-bond table put the French ten-year OAT at 3.69% and the German Bund at 2.98% on 12 June. The yield is the annual return investors demand for lending to a state. When it rises, governments pay more on new borrowing and on debt they have to refinance. Existing bondholders take the hit because bond prices fall as yields rise. New buyers get a better return, but only because the risk has been repriced.

That is where the market story becomes a political one. Every extra euro spent on interest is a euro unavailable for defence, welfare, investment or tax cuts. A looser budget, without savings that investors believe, would ask markets to trust that discipline will arrive later. If they do not, they demand a higher yield, and the debt bill rises again.

The wider euro-area backdrop is not forgiving. The European Fiscal Board expects the euro-area headline deficit to reach 3.5% of GDP in 2027, with debt above 90% of GDP. France cannot present itself as a minor exception inside that picture. An ETAF tax-policy summary said France had taken effective action under the EU deficit procedure, the Brussels process for forcing excessive deficits back into line. The next budget is the real test.

There is also the European Central Bank’s backstop to think about. Its TPI bond-buying tool depends on fiscal compliance, debt sustainability and sound policies, according to the ECB criteria. If France passes a visibly weak budget, any later argument for ECB support becomes politically and legally harder.

Where The Squeeze Lands

The first squeeze is domestic. Creditors get paid before ministers make choices. Departments looking for new money, local authorities depending on transfers and voters expecting protected services all meet the same order of priority: interest comes first.

Defence shows the collision plainly. France spends about 2.4% of GDP on defence in the latest NATO tracker, while the Senate review of the military programming update described an additional €36bn effort over the programming period. That may be strategically necessary. It still has to fit into the same budget as debt interest and deficit correction.

Italy gains a kind of status from the shift, though not much comfort. According to QuiFinanza, the Italian ten-year BTP stood at 3.87%, the French OAT at 3.74% and the Bund at 3.08% on 11 June. There is no longer much distance between Rome and Paris. The old eurozone hierarchy, with France safely in the core and Italy treated as permanently suspect, looks less solid. Italy still pays if French pressure lifts the wider euro-area risk premium.

Germany benefits as the benchmark borrower, but it is not insulated politically. Staatsanzeiger, citing ZEW-linked analysis, reported that EU common debt could exceed €1.15tn by 2030 and put Germany’s potential burden at about €120bn. A wider French premium strengthens Bunds as the eurozone safe asset, while reviving German arguments about who ultimately stands behind European commitments.

Spain Shows The Missing Piece

The numbers do not yet point to a crisis. Eco3min places a 60-80 basis-point OAT-Bund spread in a moderate-tension zone and treats sustained levels above 100 basis points as the more serious threshold. France is being repriced, not shut out.

The missing evidence sits inside the budget process: which spending bids survive, which ministries take cuts, and whether Parliament can pass something markets believe will last. Spain shows the contrast. Hacienda’s published deficit path puts the deficit at 2.1% in 2026, 1.8% in 2027 and 1.6% in 2028, even with defence flexibility. France’s question is more political: whether a government without a reliable majority can make the figures credible before the spread says patience has run out.
