The sell-off in French government debt pushed 10-year yields past equivalent US Treasury yields for the first time since 2013, according to market data. The difference between French and German 10-year borrowing costs, a key risk premium measure, rose to its highest level in almost 15 years.
The volatility comes as France struggles to approve next year's budget. Tens of thousands of people held peaceful marches demanding more teachers and repairs to run-down schools, but clashes with police erupted in Paris, Bordeaux, Nice and Marseille. Public buildings were attacked, and thousands of shops and businesses were looted. The interior ministry reported nearly 2,400 arrests.
A parliamentary deadlock has blocked President Emmanuel Macron's plans to raise the state pension age from 62 to 64 and implement measures to curb state spending. France's budget deficit stood at 5.1% of gross domestic product in 2025, while public debt reached 115.6% of GDP. Higher inflation, triggered by the war in Iran, has added to the pressure on heavily indebted governments.
Jim Reid, a market strategist at Deutsche Bank, said the French sell-off was spilling over to other countries. "Among others, the Italian 10-year spread over [German bonds] widened 3.8 basis points to 116 basis points, while Spain's widened 3.1 basis points to 66 basis points, marking its widest level since June 2025," he said.
Carsten Brzeski of ING said rising yields had reinforced the European Central Bank's restrictive monetary policy stance ahead of its interest rate decision next week. The ECB last raised its key rate to 2.5% in September. "The ECB is very likely to stay on hold next week and will delay any next rate hike decision to December," Brzeski said. "Any solution to the current French fiscal woes could bring some relief to bond markets and allow the ECB to continue hiking rates. Without any solution, bond markets have taken over the ECB's role, making rate hikes less likely."
