France-Germany 10-year yield spread passes 100 basis points for the first time since 2012
As the finance ministry announced that public debt will reach 119.3% of national income in 2026, the risk premium France pays relative to Germany passed 1 percentage point for the first time since the euro crisis.
The gap between the French 10-year bond yield and the German yield at the same maturity passed 100 basis points on 19 September 2026, crossing the 1 percentage point threshold for the first time since the 2011-2012 euro area debt crisis. As of 18 September the spread stood at 97.9 basis points; the French 10-year yield was around 4.48% and the German yield around 3.50%. The spread was about 60 basis points in April 2026, meaning it has roughly doubled in five months. Against that, it is still only half the crisis peak of about 190 basis points seen at the end of 2011.
The trigger was the finance ministry's public finance projections. The ministry forecasts the ratio of public debt to national income at 119.3% for 2026 and 121.7% for 2027; the ratio was 115.7% in 2025 and below 100% in 2019. The ministry calculates the 2026 budget deficit at 5.4% of national income; Prime Minister Sébastien Lecornu said he expects the deficit to come in clearly below 5.5%. Sources conflict: one assessment based on market analysis puts debt at 117% and the 2026 deficit at 5.1%, against official ministry figures of 119.3% and 5.4%.
Lecornu has proposed a savings package of 54 billion euros (about 62 billion dollars) for the 2027 budget and is aiming to bring the deficit down to 5% in 2027. Whether the package passes parliament is uncertain, given a divided chamber and cost-of-living pressure. On the market side bond auctions continue to be covered; this suggests the picture is less one of panic than of heightened caution pricing doubt over the political capacity to deliver 54 billion euros of cuts within 12 months.
Talay assessment
Bottom line
The 100 basis point threshold is symbolic rather than technical: the market no longer prices France in the same risk category as the euro area core. The projection that debt will reach 121.7% in 2027, together with the parliamentary test facing a 54 billion euro savings package, makes it likely that the premium becomes entrenched. The most likely path is that the spread stays elevated in a 90-110 basis point range; an upward break is a risk if the budget crisis deepens.
Likely effects
- Euro area bond marketNegative1–6 months
The spread widening from 60 basis points in April to above 100 shows sovereign differentiation being repriced across the euro area; Italian and Spanish premiums also reposition relative to France.
- French banksNegative1–6 months
A 10-year yield at 4.48% impairs valuation and collateral costs at banks carrying heavy holdings of government bonds on their balance sheets; credit conditions tighten.
- Türkiye's euro-denominated borrowingNegative1–6 months
A reopening of risk premia in the euro area core raises the reference cost on euro-denominated issuance; upward pressure builds on Türkiye's euro eurobond and syndication costs.
- 2027 budget politicsNegative6 months+
Dilution of the 54 billion euro savings package in a divided chamber could leave the deficit above the 5% target and push debt beyond the 121.7% projection.
Possibilities, ranked
- 1The premium becomes entrenched in a high range50%
The spread fluctuates in a 90-110 basis point range; the budget process is painful but auctions continue to be covered and pricing does not shift to crisis levels.
Watch: The 10-year OAT-Bund spread staying below 110 basis points at weekly closes, and bid-to-cover ratios at AFT auctions
- 2Narrowing as the budget passes30%
The 54 billion euro package is legislated largely intact, the 2027 deficit converges on the 5% target and the spread pulls back below 100 basis points.
Watch: Adoption of the 2027 budget law between October and December and the deficit target being held at 5%
- 3Political crisis and a fresh upward break20%
The government falls over the budget or the package is largely gutted; the spread moves above 130 basis points and fresh rating pressure comes onto the agenda.
Watch: No-confidence attempts in parliament and the spread passing 130 basis points
