European Central Bank President Christine Lagarde has firmly rejected a proposal by French left-wing presidential candidate Jean-Luc Mélenchon to cancel the portion of France's public debt held by the country's central bank. Speaking at a press conference after the ECB's latest interest rate decision, Lagarde described the idea as “really not a good idea” and warned that it would constitute a “clear violation of the treaty” governing the European Union.
Mélenchon, leader of La France Insoumise (LFI), has revived a proposal first floated during the COVID-19 pandemic. His plan would involve cancelling the roughly 18% of French government debt currently held by the Banque de France. He argues that such a move would relieve the state's financial burden and free up resources for social and environmental spending.
The proposal has sparked fierce debate in France, where the presidential election is scheduled for April next year. Philippe Aghion, winner of the 2025 Nobel Prize in Economics, called the idea “catastrophic”, while French Prime Minister Sébastien Lecornu warned that it would “destroy France's most important asset”, namely “trust”.
Lagarde's rebuke underscores the legal and institutional constraints that bind the ECB and national central banks within the eurozone. Article 123 of the Treaty on the Functioning of the European Union explicitly prohibits the ECB and national central banks from purchasing government debt directly from public authorities, and by extension from cancelling such debt once acquired. The prohibition is a cornerstone of the EU's monetary framework, designed to preserve the independence of central banks and maintain price stability.
Mélenchon first floated the idea during his 2022 presidential campaign. In August, he revived it with a provocative image, saying: “You just have to go to the Banque de France, take the debt securities and throw them into the fire.” His rhetoric has resonated with parts of the electorate frustrated by austerity measures and rising living costs.
Recent polling suggests Mélenchon could be a serious contender in the first round of the presidential election. A Toluna-Harris Interactive poll puts his support at around 16%, up from 12% in April, giving him a credible chance of reaching a second-round run-off. His campaign has focused on wealth redistribution, a green transition, and challenging what he calls the “financial oligarchy”.
The ECB's own monetary policy has come under scrutiny as it continues to raise interest rates to combat inflation. Lagarde's comments came after the bank announced another increase in its key rates, a decision that has drawn criticism from some politicians in southern Europe who argue that tighter policy risks choking off growth. The debate over debt cancellation is part of a broader conversation about the limits of monetary solidarity within the eurozone.
While Mélenchon's proposal is unlikely to gain traction in Brussels or Frankfurt, it highlights a growing political divide over how to manage public finances in the post-pandemic era. Some economists argue that the ECB's bond-buying programmes, which have accumulated significant sovereign debt on its balance sheet, have already blurred the line between monetary policy and fiscal support. Others insist that any move towards debt cancellation would undermine the credibility of the entire European project.
For now, Lagarde's dismissal is a clear signal that the ECB will not entertain such proposals. The institution remains committed to its mandate of price stability, even as political pressure mounts from various quarters. As France heads towards a pivotal election, the debate over debt and sovereignty is likely to intensify, with Mélenchon positioning himself as the champion of a more interventionist state.
The controversy also echoes broader tensions within the EU over fiscal rules and the future of the Stability and Growth Pact. With several member states struggling with high debt levels, the question of how to reconcile democratic accountability with monetary discipline remains unresolved. Lagarde's blunt rejection may settle the immediate argument, but it does not address the underlying frustrations that fuel such proposals.
In the meantime, the ECB's focus remains on taming inflation, which has proven stubbornly high across the eurozone. The bank's rate hikes have been met with mixed reactions, and the economic outlook remains uncertain. As the presidential campaign heats up, Mélenchon's radical proposals are likely to keep testing the boundaries of what is politically and legally possible within the EU framework.
