Rising French Borrowing Costs Spark ECB Intervention Debate

French borrowing costs are rising sharply, sparking concerns among central bankers. Emmanuel Moulin, head of the French central bank, warned that the country risks being 'strangled by interest rates' if no action is taken. The French government has proposed €43bn in budget cuts for 2027, but passing these measures through a divided parliament remains uncertain.

Investors are selling French bonds, increasing borrowing costs compared to German benchmark Bunds. The spread between French and German bond yields has surged, reaching 139 basis points, up from a historical average of 50 basis points. French economist Shahin Vallée noted that in just three weeks, higher debt-servicing costs could amount to €15bn annually over a 10-year horizon, totaling nearly €100bn cumulatively.

The French government could bypass parliament or push through the budget by ordinance, but both options carry risks. A no-confidence vote could be triggered, or the process could drag on for months. Even if approved, the budget may not stabilize French debt, according to Charlotte de Montpellier of ING.

The European Central Bank (ECB) could intervene by buying French bonds under its Transmission Protection Instrument (TPI), but this tool comes with conditions. The ECB is likely to act only if the threat to EU economic stability becomes 'existential,' with spreads approaching 250 basis points. French finance minister Roland Lescure insists the country does not need ECB intervention, but the question remains: how bad will things have to get before the ECB steps in?
