France faces calls to cancel €600 billion in public debt as fiscal pressure mounts

Jean-Luc Mélenchon, the veteran leftist firebrand running for France’s 2027 presidential election, wants to make €600 billion in public debt disappear. Not pay it off. Not restructure it. Cancel it outright.

The target: bonds held by the Bank of France on behalf of the Eurosystem, accumulated during years of European Central Bank quantitative easing. Mélenchon argues those securities represent roughly 18% of France’s total public debt and that erasing them would free up fiscal space without hurting private creditors.

The numbers behind the panic

France’s public debt hit €3.536 trillion at the end of Q1 2026, equivalent to 117.5% of GDP. That’s an increase of €75.6 billion from the previous quarter alone.

For context, France’s debt-to-GDP ratio sat at about 20% in 1980 and around 60% at the turn of the millennium.

Interest payments on that mountain of obligations are projected to exceed €77 billion in 2026.

France also needs to raise approximately €310 billion this year just to refinance maturing debt.

Why officials are sounding the alarm

Prime Minister Sébastien Lecornu and Economy Minister Roland Lescure have not been subtle. Both have labeled the proposal a form of fraud, warning it could trigger a financial crisis and push France closer to an exit from the euro.

Their argument rests on a straightforward legal reality: EU treaties explicitly prohibit the monetary financing of governments. Canceling debt held by a central bank within the Eurosystem would effectively transform past QE operations into permanent fiscal transfers, a line the ECB has repeatedly said it will not cross.

Olivier Blanchard, former chief economist at the International Monetary Fund, has echoed concerns about what such a move would do to market confidence.

Investment banker Matthieu Pigasse has floated a middle-ground alternative: freezing the debt rather than canceling it. That approach would essentially extend maturities indefinitely without the legal and reputational fallout of outright cancellation.

The broader contagion risk

The ECB accumulated trillions of euros in sovereign bonds during the 2008 European debt crisis and the COVID-19 pandemic. Those holdings were always meant to be temporary market interventions.

If the Bank of France writes off €600 billion in assets, it takes a corresponding loss. That loss would need to be recapitalized, likely by the French government itself, creating a circular absurdity where the state cancels its debt to its central bank and then has to inject capital back into that central bank.

With the presidential election scheduled for late August 2026, the proposal sits at the intersection of fiscal reality and campaign strategy.
