French Debt Cancellation Proposal Triggers Central Bank Warnings and Market Stress

A proposal by French presidential candidate Jean-Luc Mélenchon to write off debt held by the central bank drew sharp pushback from European financial officials.

PARIS — Far-left French presidential candidate Jean-Luc Mélenchon has called for the cancellation of national debt held by the country's central bank, drawing warnings from European monetary authorities and driving French sovereign bond yields higher.

Mélenchon proposed that the Bank of France write off its 18 percent holding of French government debt to free up fiscal space for social spending. The proposal comes as France’s national debt exceeds 116 percent of gross domestic product, while its budget deficit remains near 5 percent, well above the European Union's 3 percent threshold.

Central bank governors and French government leaders rejected the plan. Deutsche Bundesbank President Joachim Nagel stated that debt cancellation by central banks within the Eurosystem is prohibited under European treaties as illegal monetary financing, warning the strategy could trigger hyperinflation. French officials also warned that reneging on obligations would dramatically increase state borrowing costs as the treasury prepares to issue more than $360 billion in debt this year.

Financial markets reacted nervously to the proposal and ongoing fiscal uncertainty. The yield spread between French and German 10-year sovereign bonds widened toward 90 basis points, approaching peak levels last recorded during the 2012 European debt crisis.

Market strategists monitor the 90-basis-point yield differential as a critical metric of investor confidence, cautioning that sustained pressure on French debt could create spillovers across interconnected European sovereign bond markets.
