Pressure in the French bond market is shifting from a story of fiscal imbalance into a political battle involving the central bank, the government and presidential candidates all at once.

On 7 October, Emmanuel Moulin, a member of the ECB Governing Council and Governor of the Banque de France, made clear that conditions in the French bond market are "severe and complex" but have not yet met the bar for ECB intervention. "The ECB does not exist to handle the fiscal problems of individual countries," he said, adding that France must resolve its own problems through budget and fiscal adjustments.

French government bonds have been hit by a wave of selling, with the spread between 10-year French bonds and German bonds once widening to around 160 basis points, the highest since the 2011-2012 eurozone debt crisis. Although the spread narrowed to about 127 basis points on Tuesday as some investors stepped in, market concern over the sustainability of France's public finances has not faded. With the presidential election approaching, the market is already pricing in the fiscal path of the next government.

Far-right candidate Marine Le Pen advocates deep spending cuts and a lower deficit, while also hoping the ECB will help ease financing pressure; far-left candidate Jean-Luc Melenchon has proposed freezing or cancelling part of France's government debt. The two approaches point in opposite directions, yet both reflect France's current debt and fiscal constraints, meaning the election outcome could further shift market expectations for French fiscal policy.

The ECB Draws a Red Line: Fiscal Problems Are Outside the Rescue Mandate

Moulin's core judgment is that France currently faces a fiscal problem, not a liquidity problem that the central bank can solve directly.

He said France needs to restore fiscal credibility through a budget bill and push its deficit below 5% of GDP, rather than hoping the ECB will use bond purchases to hold down financing costs. "The situation is severe," Moulin said. "But we can act by voting through a budget and committing to a deficit no higher than 5%."

This position puts him in direct conflict with Le Pen's demands. Le Pen has previously called on the ECB to act to free up more fiscal space for France and other eurozone countries for defence and technology investment; in her latest fiscal plan she also said that once France regains control of its public finances, it will need to discuss with the ECB how to lower borrowing costs.

But the ECB's policy tools are not an unconditional fiscal rescue. The French government expects this year's fiscal deficit to reach 5.4% of GDP, while the 2027 budget draft seeks to bring it down to 5%; at the same time, the government has proposed around 54 billion euros of fiscal adjustment, though whether it can win parliamentary support remains uncertain.

So what the bond market is really watching is not only whether France can secure central bank support, but whether the government can prove it is able to control the deficit and stabilise debt. Moulin's remarks effectively set the policy boundary: fiscal imbalance must first be addressed through fiscal policy, and the central bank will not take on the government's fiscal consolidation burden.

Le Pen's "Shadow Budget": Can Deep Cuts Win Back Market Trust?

As pressure in the bond market builds, Le Pen is trying to prove through a more aggressive fiscal plan that if she takes power, cutting the deficit and debt will be her priority.

On 6 October, Le Pen unveiled her latest fiscal roadmap, proposing 140 billion euros of net savings by 2032 compared with 2026, and planning to bring the fiscal deficit below 3% of GDP by 2030 and further down to 2.5% by 2032, while reducing the public debt ratio to around 112%. Compared with an earlier target of 125 billion euros in savings, this plan increases the scale of fiscal adjustment.

The savings would mainly come from squeezing spending by local governments and government agencies, cutting some foreign aid, reducing France's net contribution to the EU budget, cracking down on tax fraud, and lowering public spending through immigration policy. The plan also includes at least 30 billion euros of tax cuts, alongside tax increases targeting high-net-worth individuals, companies and share buybacks.

But whether the plan can be delivered remains disputed. The French government has publicly questioned its savings estimates, while the market is more focused on whether such a large-scale fiscal adjustment can win parliamentary support and whether some savings items can truly translate into fiscal improvement.

Le Pen said that as interest rates rise, France must accelerate fiscal adjustment; only by restoring fiscal autonomy can financing pressure be eased. She also argues that once France regains control of its public finances, it should discuss lowering debt financing costs with the ECB.

In other words, Le Pen's path is to first restore market trust through fiscal austerity and then seek lower financing costs; Moulin's remarks mean France cannot pin its hopes on the ECB providing a backstop.

Melenchon's Head-On Clash With the Central Bank

If Le Pen is trying to ease debt pressure through spending cuts, Melenchon has proposed a different path. Melenchon has previously suggested freezing or cancelling part of France's government debt held by the Banque de France and the European Central Bank, hoping to directly reduce the government's debt burden. But the proposal met clear opposition from the monetary authority.

On 11 September, Banque de France Governor Emmanuel Moulin described debt cancellation as "illegal, dangerous and useless," arguing that it violates EU treaties, could drive up inflation and interest rates, and would not solve the root problem of France's persistent fiscal deficits. ECB President Christine Lagarde has also said that cancelling French debt held by the ECB would violate EU treaties.

Controversy then intensified over the decline in the Banque de France's debt holdings. On 12 September, the Banque de France issued a statement clarifying that the fall in its holdings of French government bonds was not active selling, but the result of not reinvesting maturing bonds it had previously purchased. As of the end of June 2026, the Banque de France held 488 billion euros of French public debt under the relevant asset purchase programme, down from 546 billion euros at the end of 2025, all due to bond maturities.

The dispute escalated further on 6 October. Melenchon publicly criticised Moulin, even calling his warnings about France's fiscal situation "treasonous," and said that if the left-wing alliance takes power in 2027, he would hold him accountable. Moulin has already made clear he will not resign or change his position because of political pressure.

At this point, the argument has moved beyond specific debt policy and reached deeper questions of central bank independence, EU fiscal rules and the monetary policy framework.

Macron's Decade of Economic Legacy: Reform Gains Alongside Fiscal Strain

France's current debt pressure did not emerge overnight, but accumulated through long-term fiscal deficits, large-scale spending during crises and blocked fiscal consolidation in recent years.

After taking office in 2017, Macron pushed supply-side reforms that helped improve employment and investment, but France's long-standing problems of high public spending and structural deficits were not fundamentally reversed. Later, the Yellow Vest movement, the pandemic and the energy crisis pushed spending even higher, with French public debt rising from about 98% of GDP in 2019 to 119% in June 2026, reaching around 3.596 trillion euros.

At the same time, political fragmentation has made fiscal consolidation even harder. After the snap parliamentary election in 2024, two prime ministers left office in succession, and fiscal reform was repeatedly blocked. The current government plans around 54 billion euros of fiscal adjustment to bring the projected 2026 deficit of 5.4% down to 5% in 2027, but whether the budget can win parliamentary support remains uncertain.

Pressure in the bond market has risen accordingly: the yield on 10-year French government bonds once approached 5%, and the spread over German bonds once widened to around 160 basis points, the highest since the 2011-2012 eurozone debt crisis. Meanwhile, the French government plans to issue around 340 billion euros of medium- and long-term government bonds in 2027, keeping financing pressure high.

High debt and high deficits push up financing costs, and financing costs in turn add to fiscal pressure, while political fragmentation further weakens market confidence that fiscal consolidation will continue. With the ECB making clear it will not backstop fiscal problems, France must ultimately rely on its own fiscal adjustment to stabilise the bond market.
