Let them eat bonds

France is providing a rather uncomfortable illustration of what happens when the global bond market begins questioning governments’ ability to live with their debts. Its 10-year sovereign yield breached 5 percent last week for the first time since 2002, even as US Treasury yields retreated, while the premium over German bonds reached levels last seen during the eurozone debt crisis.

With violent unrest accompanying widespread protests over living costs, France has become a particularly revealing case study of the forces now unsettling sovereign debt markets. And the obvious question is whether other heavily indebted economies are heading towards a similar confrontation between financial arithmetic and political reality.

The French predicament has been building for years. Government debt is approaching 120 percent of GDP, the fiscal deficit remains around 5 percent, and nominal economic growth is expected to reach barely 3 percent. Those numbers were easier to accommodate when borrowing costs were negligible. But as bonds issued during the era of exceptionally low rates mature, the government must refinance them at considerably higher yields. The resulting increase in interest payments adds to deficits, which require more borrowing, leaving investors increasingly concerned about the sustainability of the entire arrangement.

The arithmetic becomes particularly troublesome when a government is already approaching the limits of what it can raise through taxation. French public revenue amounts to roughly 52 percent of GDP, among the highest proportions in the developed world. Spending reductions offer an alternative, but pensions, public services and social protections have become politically difficult to touch. And with parliament divided into antagonistic blocs, even a credible fiscal adjustment programme faces formidable obstacles. How does a government convince bondholders that it can eventually balance its books when voters appear unwilling to accept either higher taxes or lower spending?

Yet the unrest also raises a question that the bond market’s focus on fiscal discipline can easily overlook. President Emmanuel Macron has acknowledged the genuine inflation-related grievances behind the protests. The looters and vandals deserve no defence, but ordinary citizens protesting the erosion of their purchasing power have legitimate concerns. There is something distinctly Marie Antoinette about expecting households struggling with soaring prices to accept another helping of fiscal austerity simply because the bond market demands it. France is experiencing an energy-driven inflationary shock that has been aggravated by the US-Israeli war against Iran, a conflict in which Paris had no part in the decision to launch hostilities. That distinction matters when assessing both the origins of public anger and the political limits of austerity.

Consider how the shock travels. Disruptions to energy production and shipping in the Middle East raise the cost of crude oil, diesel and natural gas. Those increases filter through transport, electricity, manufacturing and eventually consumer prices. Higher inflation then complicates the European Central Bank’s monetary policy calculations, while households demand protection from rising costs. Governments facing those demands must either spend more, cut elsewhere or tolerate growing public discontent. For France, already struggling with its fiscal position, each option carries consequences for financial confidence or political stability.

This is where Donald Trump’s decision to follow Benjamin Netanyahu into war against Iran becomes relevant to a discussion that might otherwise appear confined to French public finances. Washington’s military intervention has helped generate economic consequences far beyond the battlefield, exposing countries with no direct involvement in the conflict to higher energy costs and inflationary pressures. France’s debt problem predates the war by decades, but the external shock has made its fiscal and political contradictions considerably harder to manage. How many governments can sustain public confidence when they are being asked to repair longstanding financial weaknesses while absorbing the consequences of someone else’s geopolitical calculations?

Investors, meanwhile, are becoming less accommodating. The widening spread between French and German sovereign yields reflects growing concern about France-specific fiscal and political risks. Funds that previously bought French debt to earn a relatively attractive yield premium have begun reassessing those positions, and selling pressure can reinforce itself as borrowing costs rise. The problem is especially awkward because higher yields eventually feed directly into the fiscal deficit as older, cheaper debt is refinanced. Markets are effectively demanding evidence of fiscal discipline while making the achievement of that discipline progressively more expensive.

There is considerable historical irony here. During the eurozone crisis, France stood alongside Germany in insisting that Greece and other heavily indebted countries accept painful adjustments. Now Paris finds itself confronting familiar questions about debt sustainability, political resistance and the constraints of a common currency. Unlike governments that issue debt in currencies they independently control, France cannot instruct its central bank to create euros to finance its obligations. ECB possesses mechanisms to address destabilising market conditions, but its intervention would come with institutional and policy constraints.

Still, France is some distance from an outright sovereign debt crisis. A 5 percent yield, however uncomfortable, does not automatically imply insolvency, and the eurozone has stronger financial safeguards than it possessed during its earlier crisis. The deeper concern is whether political institutions can produce a sufficiently credible fiscal plan before rising borrowing costs further restrict their choices. Markets may tolerate substantial debt when they believe governments can stabilise it. That confidence becomes harder to sustain when every proposed adjustment threatens another round of political upheaval.

And the implications are hardly confined to France. Italy and Belgium face their own fiscal vulnerabilities, while Britain remains sensitive to gilt yields and public spending pressures. Across Europe, the combination of expensive borrowing, strained public finances and resistance to austerity raises uncomfortable questions about how governments intend to reconcile fiscal discipline with political stability.

The consequences become potentially more severe beyond Europe, particularly for emerging economies with limited fiscal flexibility and greater exposure to external financing pressures. Pakistan offers a relevant example, given its dependence on imported energy, recurring fiscal imbalances and vulnerability to shifts in global borrowing conditions. The common thread is the growing difficulty of financing political promises through debt when inflation and interest rates no longer cooperate.

Perhaps France will eventually find a workable compromise between fiscal consolidation and social protection. But its present troubles expose a broader contradiction in the global financial system. Governments spent decades accumulating obligations under the assumption that borrowing would remain affordable, while political expectations expanded accordingly. Now bond investors are demanding discipline precisely when households are struggling with higher living costs, partly aggravated by a war that many of their governments neither initiated nor control. If France is already discovering how difficult that combination can become, what should the rest of the indebted world expect when the same pressures arrive at its door?
