Why are French government bond yields surging?
France’s 10-year government bond yield reached about 4.89% on October 19, near its highest level in more than two decades. The problem is rising debt, persistent budget deficits and political uncertainty.
French public debt is approaching 119% of GDP and the budget deficit remains around 5%. Investors increasingly doubt that a divided parliament can agree on the spending cuts and tax measures needed to stabilise the debt. Violent protests over living costs and proposed spending cuts have added to those doubts ahead of the 2027 presidential election.
The market signal is particularly clear when compared with Germany. France now pays roughly 1.45 percentage points more than Germany to borrow for ten years. That difference represents the additional return investors demand for holding French government debt.
There is also a growing financial consequence. France plans to issue €340 billion in medium- and long-term government bonds in 2027. Its Treasury expects annual debt-service costs to rise from €62.6 billion in 2026 to €72.9 billion in 2027.
Higher yields do not immediately increase interest payments on existing fixed-rate bonds. But as those bonds mature, France must refinance them at prevailing market rates.
France can still borrow. The deeper problem is that political divisions make fiscal reform difficult while rising borrowing costs make those reforms increasingly urgent. The longer the adjustment is delayed, the greater the pressure on future budgets.
