Germany borrows for ten years at about 3.3 per cent. France borrows the same money over the same ten years at about 4.2. The gap comes to €850 a year on every €100,000, and it exists because several thousand people are obliged to put a price on French creditworthiness before lunch every day.
Picture a house that strangers value out loud every day, whether or not anyone means to sell. That is what happens to sovereign debt, and to nothing else a country owes.
The accounts that get a coupon
A government carries at least six debts, and only one of them trades.
- Fiscal debtA market, a maturity date and a daily quote
- The infrastructureIts condition, deferred one budget at a time
- Plant and control systemsRenewal put off until something stops
- Supplier dependencyA step that used to be done in-house
- The grid queueProjects waiting on a connection date
- Know-howThe people who know how the thing is actually made
Only the first carries a price, a maturity, or anybody obliged to publish a figure for it.
Discipline follows the quote. Where somebody has to produce a figure every morning the liability gets managed, and where nobody has to, it settles late, in cash, at a moment the asset chooses.
The transfer
Consolidation moves money. The question is which account it moves it from, and the answer is whichever one cannot complain.
Pensions are politically priced and therefore defended. Renewals budgets are not, so when a finance ministry needs a number by March the maintenance line is the one that gives: deferring it produces no headline, no strike and no spread widening. The visible debt falls by the amount deferred. The invisible one rises by more, because deferred maintenance compounds at the rate of asset decay, and asset decay is not linear.
Fiscal consolidation is rarely paid for. It is re-registered.
The repricing event
Germany ran this experiment for a quarter of a century under a constitutional debt brake, and in 2025 published the result. A two-thirds majority amended the Basic Law to create a €500bn special fund for infrastructure and climate neutrality over twelve years, sitting outside the brake entirely. What the fund pays for reads as a maintenance list: motorway tunnels, rail capacity, hospitals, care facilities.
The 2022 network state report put the age-based backlog at €103.4bn of replacement value, with bridges alone accounting for €59.9bn of that. By January 2025 Deutsche Bahn was asking for around €150bn from the new fund, €80bn of it simply to repair the network already in the ground, against long-distance punctuality of 62.5 per cent across 2024 on a six-minute threshold.
Calling that new spending mistakes the entry for the event. Three decades of accrued liability were admitted to the ledger at 2025 prices, having been incurred at 1998 prices. The brake postponed the borrowing and enlarged it.
What repricing looks like from inside
France runs the same accounts against a different asset. The Grand Carénage is the refurbishment of a reactor fleet built in one compressed burst and now renewing in another: €55bn at the 2015 estimate, optimised to €45bn in 2018, adjusted to €49.4bn in 2020.
Those last two figures sit on different price bases. EDF publishes the 2018 optimisation as €48.2bn in current euros in the same release, and that is the number the 2020 estimate should be read against. Like for like the movement is a little over a billion. The estimate fell while it was being optimised on paper, and rose once the inspections came back.
An unpriced liability holds a real value throughout. The value becomes visible only when somebody opens the casing, and what the opening finds is seldom smaller than the paper said.
What actually closes the account
Three of these can be closed. The fourth has no mechanism at all, because it is the only one where money does not work.
A bridge backlog can be cleared by a government willing to sign, and a machine tool can be bought with a lead time. Moving a process out of the head of someone who has run it for thirty years and into somebody else's takes roughly as long as it took the first person to learn it, and it can only begin while that person is still on site.
Every other debt has a settlement mechanism. This one has a retirement date.
The measurement problem
The objection to all this is that unpriced debt goes unpriced because it is soft. Maintenance backlogs are estimates produced by the people who want the budget, and know-how deficits are asserted by the people selling the remedy. Both objections are fair, and arguing about the categories will not answer either.
Instrumentation will. A maintenance backlog is measurable as renewals deferred against renewals scheduled, by asset class, restated annually at current prices, which is what the German network state report does and most national accounts do not. A know-how position is measurable too, though publishing it takes more nerve: the count of processes with a single qualified holder, the age distribution of that population, and the number of first-article approvals a plant can sign without outside help.
Accounts with no coupon compound anyway, and the only question is whether anybody opens them before the asset does. A debt nobody has chosen to measure still arrives in the accounts eventually, in the form of a stoppage.
Manufacturing Engineers open those accounts. They inventory the processes that rest on one person, qualify second sources while the first is still in the building, restate deferred capex at what catching up will actually cost, and instrument the plant so that decay carries a number before it carries a consequence.
