The most unsettling and profound shift in the European bond market right now is that France is losing its traditional status as a core Western nation with superior financing advantages.

On October 9, the yield on France's 10-year government bonds exceeded that of Italy by 30 basis points, setting a record high since the birth of the euro; the spread between French and German bonds briefly breached 150 basis points last week, returning to extreme levels not seen since the eurozone debt crisis nearly two decades ago.

France's 10-year yield has risen nearly 80 basis points since early September, approaching 5% and reaching its highest level since 2002.

With fiscal deficits proving difficult to reduce, budget execution constrained by political gridlock, and the spillover effects of surging 10-year and longer-dated U.S. Treasury yields driving up global long-term funding costs, France is being pushed into the center of a European bond market storm.

The latest statistics show that global bond investors are demanding the highest extra compensation since the euro was created for holding French government bonds over Italian ones.

On Friday, the yield gap between the two countries' benchmark 10-year bonds reached a record 30 basis points.

Until last year, Italy was still considered the riskier of the two sovereign bond markets, with higher borrowing costs than France.

Now, investors are punishing France because it has fallen short of expectations in cutting its budget deficit, with no sign of reducing its debt-to-GDP ratio of 117.6%.

Fund managers are also demanding higher yields to compensate for political uncertainty ahead of next April's presidential election, when the far right and far left could face off.

Meanwhile, Italy has earned market rewards for its bonds after years of difficult fiscal austerity that reduced government debt levels and boosted economic growth.

Although Italian government bonds have been hit hard in the recent selloff, investors believe the declines lack sufficient justification.

Alex Everett, who manages the euro government bond fund at Aberdeen Investment Management, said: "In recent weeks, spreads in some European markets have widened alongside France, and we see opportunities in that. Given the overall strength of an integrated EU and better debt trajectories, Italy, Spain, and some smaller markets are poised to outperform."

As shown in the chart above, the 10-year yield premium of French government bonds over Italian bonds has hit an all-time record — under fiscal and political strain, French bond yields have already risen to the highest level in the eurozone.

French government bonds have also lagged behind other European countries, but the change relative to Italy is particularly notable because Italy has long been seen as the bellwether for eurozone sovereign risk.

At the height of the eurozone debt crisis in July 2012, Italy's 10-year yield was more than 400 basis points above France's.

Now the situation has reversed, with France becoming the epicenter of European bond selling.

The yield spread between France and Germany — the region's safe-haven asset — has widened to levels unseen since the eurozone debt crisis, breaching 150 basis points last week.

As the selloff stabilized, the spread narrowed by 5 basis points at one point on Friday to 135 basis points.

Irina Kurochkina, a portfolio manager at Aegon Investment Management, said investors took advantage of the recent selloff to buy cheaper bonds from countries like Italy and Spain.

However, she added that investors are still avoiding France overall.

She said: "After spreads widened, bonds from some other countries did become more attractive, especially peripheral nations with better budget positions and GDP prospects. French government bond prices have fallen enough to warrant a moderate short-covering, but given the volatility from budget discussions and escalating protests, we are not yet ready to adjust our French government bond positioning to neutral."

The Reversal of France-Italy Risk Ranking: The Eurozone Debt Crisis Alarm Shifts from the "PIIGS" to Paris

The PIIGS — Portugal, Italy, Ireland, Greece, and Spain — refers to five European countries that Wall Street uses as a derogatory label for the five eurozone economies with lower sovereign debt credit ratings.

However, this time the country that could trigger a new eurozone debt crisis is not one of the perennial laggards of the European economy — the "PIIGS" — but France, the second-largest economy in Europe.

As Europe's second-largest economy, France's government bond market is vastly larger in scale and its influence on the entire European and global economy is far greater than that of the "PIIGS" that ignited the eurozone debt crisis fourteen years ago.

A growing number of investment institutions fear that continued heavy selling of French government bonds could have spillover effects that trigger a new round of euro depreciation crisis and eurozone debt crisis impacting global financial markets.

Looking back at the previous eurozone debt crisis — it began in 2009 when Greece sharply revised up its fiscal deficit, and the post-financial-crisis recession and bank bailout burdens further exposed member states' fiscal vulnerabilities, with pressure then spreading to Ireland, Portugal, Spain, and Italy.

Falling government bonds weakened bank assets and financing capacity, while bank bailouts added to government burdens, forming a "sovereign-bank vicious cycle"; fiscal austerity further suppressed growth.

Market confidence only gradually recovered after European rescue mechanisms were progressively established, particularly after then-ECB President Mario Draghi's pledge in 2012 to do "whatever it takes" to defend the euro, and the ECB's introduction of the conditional Outright Monetary Transactions (OMT) tool.

This time, the eurozone debt crisis alarm is pointing first at a core eurozone economy.

Although the bond market got some relief on Friday — France's 10-year yield fell back to about 4.825% in early European trading, and the French-German spread briefly narrowed to 135 basis points — the brief rebound has not yet resolved the budget credibility issue.

What determines whether this storm can be calmed is whether France can convince investors that its fiscal commitments will ultimately translate into executable and deliverable monetary or fiscal policy.

U.S. Treasuries Drive Up Funding Costs, France's Finances Approach the "Credit Kill Line"

The sharp rise in U.S. Treasury yields at 10-year and longer maturities is undoubtedly providing external impetus for European debt repricing.

The U.S. 10-year yield rapidly climbed from about 4.7% at the end of August to above 5.3%; on October 8, the 10-year and 30-year yields touched approximately 5.35% and 5.73% intraday, respectively, before falling back to about 5.23% and 5.61% on strong demand at long-term Treasury auctions.

Such a rapid upward shift in long-end rates within weeks means global investors are demanding higher returns before they are willing to continue bearing the price volatility and inflation risks of long-term bonds.

From a pricing mechanism perspective, long-term yields are determined by future short-term rate expectations and term premiums.

Energy shocks raise inflation risks, massive government debt issuance and AI infrastructure financing increase funding demand, and central bank balance sheet reduction reduces steady buying; therefore, even if expectations for a particular rate hike cool, long-term funding costs may still rise.

The U.S. Treasury shock transmits to Europe through global portfolio reallocation and term premium linkages, while Europe itself also faces pressure from increased debt issuance and the ECB no longer reinvesting maturing bonds.

France, in addition, bears the impact of an expanding fiscal and political risk premium.

The most dangerous contradiction in the French government bond market and indeed the entire French fiscal system is that interest expenses are eroding the space for fiscal consolidation.

According to the latest data from France's statistics agency, public debt reached approximately 3.60 trillion euros in the second quarter, or 119.0% of GDP.

The government forecasts economic growth of just 0.5% in 2026 and a deficit of 5.4% of GDP; even with 54 billion euros in fiscal consolidation in 2027, the deficit target remains 5%.

At the same time, interest expenses are projected to rise from 79.2 billion euros to 91.2 billion euros, an increase of about 15%.

New and maturing refinancing is becoming increasingly expensive, while fiscal adjustment is constrained by low growth, a divided parliament, and electoral pressure, making it easy to form a feedback loop of "rising interest — blocked fiscal improvement — further rising risk premium."

The key trigger threshold for a new eurozone debt crisis is whether sovereign stress will fully penetrate bank financing and real economy credit.

If continued declines in French government bonds weaken financial institutions' asset and collateral values, and tightening financing conditions in turn suppress lending, investment, and tax revenue, France's fiscal pressure could evolve into a broader financial contraction.

The ECB has tools to block contagion, but the TPI targets financing conditions that deteriorate disorderly without fundamental justification and impair monetary policy transmission, and it must assess fiscal sustainability; therefore, it does not provide an automatic backstop for any budget imbalance.

The alarm for a new eurozone debt crisis has already intensified, but the market has not yet entered a phase of full-scale financing failure.

Institutions like Aberdeen and Aegon have begun buying back Italian and Spanish bonds while continuing to avoid France, highlighting that global fixed-income investment capital is rearranging European sovereign credit.

The high yields on French bonds first reflect a fiscal credibility discount; the opportunity in Italian and Spanish bonds comes from some investors' revised judgment on correlated selling.

The most critical signal to watch next is whether France's budget can be implemented, and whether domestic financing and credit pressures in France continue to spread to eurozone bank credit spreads and corporate financing.
