France bond yields hit 15-year high, markets price 2010-style debt crisis risk

French sovereign borrowing costs have surged to their highest level in 15 years, with markets drawing parallels to the 2010 eurozone crisis. The move reflects growing investor concern over France's fiscal trajectory and political instability, though a full-blown crisis remains contingent on further deterioration. This marks a significant repricing of French risk, previously seen as a safe haven.
