French Bond Yields Surpass Italy's, ECB TPI Tool in Focus
nashnova research
France's 10-year bond yield has risen to 4.51%, with the Franco-German spread nearing the 1-percentage-point psychological threshold — its highest since 2012 — as markets begin pricing in whether the ECB's Transmission Protection Instrument (TPI) could be triggered.
How high have France's borrowing costs climbed?
France's 10-year government bond yield hit 4.5531% the previous day, its highest since September 2008, before settling at 4.51%.
The Franco-German spread — the gap between French and German bond yields, a key gauge of how much extra risk markets attach to France — reached 98.15 basis points, the widest since July 2012.
This means → France now borrows at a higher cost than Italy or Greece, making it the most debt-stressed major economy in the eurozone.
Why is France's fiscal position so stuck?
The budget deficit runs at roughly 5% of GDP, yet the tax burden is already among the developed world's highest — tax revenue equals 43.5% of GDP, far above the U.S. at about 25%. In plain terms = taxes are maxed out, but the deficit still won't come down.
Debt-interest payments have overtaken public-education spending. Brigitte Granville, professor of international economics at Queen Mary University of London, says the situation is "becoming increasingly unsustainable."
This reflects a core contradiction: almost zero room to raise taxes, paired with fierce political resistance to spending cuts.
How does the political deadlock amplify the risk?
President Macron's reform raising the retirement age from 62 to 64 has been shelved after he lost control of parliament.
Marine Le Pen, the frontrunner in 2027 election polls, wants to lower the retirement age to 60 and cut fuel and electricity taxes — the exact opposite direction.
Granville argues that if France collapses, the euro collapses with it, giving France a "too big to fail" status. In plain terms = the market bet is not whether France defaults, but whether the eurozone can survive France going wrong.
Why is the foreign-ownership structure a hidden risk?
Foreign investors hold 57% of French sovereign bonds, well above the roughly 40% foreign share of U.S. Treasuries.
This means → if sentiment turns, the sell-off risk is amplified — most holders have no domestic lock-in motive, so exit pressure can concentrate fast.
Mabrouk Chetouane, head of global market strategy at Amundi, says "the market's tolerance may have reached a tipping point."
What is the ECB's TPI tool, and when might it be used?
TPI — the Transmission Protection Instrument, which authorizes the ECB to buy member-state bonds to counter "unwarranted, disorderly market dynamics" — is the central bank's still-unused backstop of last resort.
Chetouane describes it as "a nuclear-grade tool to prevent a 2012 rerun" — that year, Greece's debt default triggered a yield spike across southern Europe.
He estimates the Franco-German spread approaching 1.5 percentage points would be the key threshold to watch for TPI activation. The current spread sits roughly 50 basis points below that level.
Is this a crisis, or is there still a way out?
Steven Kamin, senior fellow at the American Enterprise Institute, notes the current spread remains well below the levels seen for Italy and Spain during the 2010s crisis.
Italian Prime Minister Meloni cut Italy's fiscal deficit from 7% to 3% of GDP over four years — a reference case. This means → if France can form a working majority after next year's election, fiscal consolidation is not impossible.
Chetouane cautions, however, that France will face at least one year of political drift after the election. "An improvement from the ballot box is far from guaranteed." If yields rise roughly 25 basis points above 4.5%, that may offer a cautious entry point.
