France's debt trajectory is now rated more dangerous than Greece and Italy by the same market that once rescued them.

A bond yield is the interest rate a government pays to borrow money. France's 10-year yield touched 4.99% in early October, its highest since July 2002. France now pays more to borrow than Italy and Greece, the two countries it helped rescue during the 2011 eurozone crisis. The spread between French and Italian 10-year bonds hit a record 30 basis points. The market is not reacting to a headline. It is repricing two decades of unresolved spending. France has not run a budget surplus since 1973.

Know this: government borrowing costs set the floor for everything else. French mortgage rates, car loans, and business credit all price off the same sovereign benchmark that is now at a 24-year high. France's interest bill is expected to hit €77 billion in 2026, more than the national education budget. That is money that cannot be spent on schools, hospitals, or wages. French households are already feeling it. UK households are too: the French sell-off pushed 30-year gilt yields to 6%, a 28-year high, triggering mortgage repricing at HSBC, Halifax and BM Mortgages this week.

Law of Entropy: systems do not hold together through intention. They hold together through active maintenance. France stopped maintaining its finances in 1973 and borrowed the difference every single year since. The political result is five prime ministers in two years and a population that will not accept either tax rises or spending cuts. People watching this feel a low-grade dread they cannot name. The mechanism underneath it is simple: when a system runs a deficit long enough, the market eventually charges for the risk everyone pretended did not exist.

Agence France Tresor, the body that manages French government borrowing, announced it will issue a record €340 billion in bonds in 2027, up 10% from this year. Most of it replaces cheap pandemic-era debt now coming due, which must be refinanced at today's much higher rates. The government's own budget assumes a 4.3% yield on 10-year bonds in 2027. Those bonds are already trading at 4.8%. The gap between the assumption and the reality will cost France billions it has not budgeted for before a single euro is spent on public services.

Know this: France's debt interest bill is rising from €62.6 billion in 2026 to €72.9 billion in 2027. That is a €10.3 billion increase in a single year, purely to service existing debt, not to build anything new. The EU's deficit ceiling is 3% of GDP. France is running at 5.4% and targeting 5%. Every 0.1% rise in the actual borrowing rate versus the budgeted rate adds hundreds of millions to that bill. The trap is mechanical: the more France borrows to pay existing debt, the higher the yield investors demand, which makes the next round of borrowing more expensive still.

Law of the Trap: the structure was built to keep you paying, not to help you escape. France entered this trap gradually, then all at once. Each prime minister promised fiscal discipline. Each budget assumed slightly better borrowing costs than the market delivered. The population feels it as frozen wages and cut services, not as an abstract yield number. The psychology here is normalisation: when the pain arrives slowly enough, people adjust to each increment rather than recognising the cumulative position. By the time the number becomes impossible, it already feels normal.

In 2022 the ECB created the Transmission Protection Instrument, known as the TPI, to buy government bonds when panic rather than fundamentals was driving yields higher. The mechanism requires the country receiving help to have sound fiscal policy and not be under an EU excessive deficit procedure. France fails both tests. Its deficit is 5.4% of GDP against an EU ceiling of 3%, and it has been under the excessive deficit procedure since 2024. Eurozone finance ministers meeting on 8 October told France to pass its budget. No institution has offered to intervene. The tool exists. The patient does not qualify.

Know this: a credit default swap is an insurance contract. You pay a premium; if the borrower defaults, you collect. France's 5-year sovereign CDS hit 81 basis points in early October, its highest since the 2013 eurozone crisis. Macquarie Group strategist Thierry Wizman stated the CDS signal means the OAT/Bund spread is now pricing genuine sovereign default risk, not just political noise. Vanguard's head of international rates described France publicly as a 'long-term degrading credit.' These are institutional fund managers, not bloggers. When they say it, they are also selling it.

Law of the Landlord: those who set the rules of access decide who gets rescued and who does not. The ECB is the landlord of eurozone sovereign credit. The TPI is the tool it built to selectively save bond markets in crisis. The eligibility criteria are the lease terms. France cannot meet the lease terms because its problems are structural, not temporary. The psychological trap for ordinary people watching this is assuming that because France is too big to fail, it will automatically be saved. It will not automatically be saved. The ECB has said so directly.
