France’s public debt poised to exceed 1970s levels, testing fiscal credibility amid parliamentary split
Executive summary: France’s public debt is projected to climb to its highest level in nearly fifty years, exceeding the debt‑to‑GDP ratio seen at the end of the 1970s. A higher debt load could push up French sovereign yields, trigger rating‑agency scrutiny and strain the Eurozone’s fiscal surveillance framework.
Who is involved: French Ministry of Economy and Finance, the National Assembly, EU fiscal authorities, bond investors and rating agencies.
Likely next: Parliament will debate a savings package in early October 2026, followed by an EU Commission assessment of France’s compliance with the Stability and Growth Pact and possible rating‑agency reviews in Q4 2026.
The French government forecasts a sharp rise in its debt burden, potentially surpassing the peak reached at the end of the 1970s. While officials pledge savings to curb the increase, the National Assembly remains deeply divided over austerity measures. The situation raises concerns about borrowing costs, credit‑rating actions and the broader stability of Eurozone public finances.
