ALL EMERGING NOW

It took forty-nine days for London to discover a truth that emerging markets have known forever.

Not a political crisis, but an arithmetic crisis.

We continue to misread the story of Liz Truss — which was not the punishment of an unstable government. Markets care remarkably little about instability in itself. They have tolerated it in France for years, and in Japan for entire generations. In London, they punished something far more specific: £45 billion in unfunded tax cuts, announced at precisely the moment when the Bank of England was refusing to provide lasting support for sovereign debt.

The crisis was therefore arithmetic first, before becoming a crisis of credibility.

One nuance makes the comparison with Paris more troubling:

while the United Kingdom borrowed in its own currency, France borrows in a currency it does not control.

Liz Truss was therefore not punished for governing in confusion. She was punished for committing a public and manifest error without appearing to understand its nature. Denying the obvious is a luxury markets refused to grant her.

The privilege enjoyed by advanced economies is the right to make mistakes within limits — that is, to be taken at their word as long as they promise to correct course. This right is enshrined in no treaty. It rests on a conviction — long justified — that the institutions of wealthy countries will ultimately regain control.

Unfortunately for them, it is precisely this conviction that is now eroding.

For thirty years, Tokyo financed our deficits. The tap is now closing.

As political erosion advances, the financial mechanism that absorbed its consequences is also undergoing a structural transformation. That is the real novelty.

For decades, Japanese savings constituted one of the great reservoirs of capital for the developed world. Life insurers, pension funds and institutional investors in Tokyo all bought U.S., British and French government bonds, as well as other foreign assets, accepting currency risk whenever the arbitrage was worthwhile. This discreet recycling helped sustain considerable demand for Western debt.

It has not disappeared, but it is becoming less self-evident.

The ten-year JGB touched 3% on September 2 — for the first time since 1996. Yields have tripled in two years! The incentive to finance European deficits mechanically diminishes when a Japanese investor can earn 3% in his own market, with no currency risk, no hedging cost and no transatlantic uncertainty. The debate in Tokyo is therefore no longer merely about the return on foreign assets, but about the relative price of domestic and external risk.

The tap is tightening quarter after quarter, at the worst possible moment: precisely as the ECB is gradually reducing its presence in the bond market through quantitative tightening, while the supply of sovereign debt remains high.

A double withdrawal — and therefore a double penalty — for European sovereign debt at the very moment when supply is increasing, that is, when European governments most need foreign financing.

In this respect, the market to suffer first will not necessarily be the one with the highest debt. It will be the one whose net supply is greatest at the very moment when marginal buyers are withdrawing, and whose government is least capable of reducing it.

Four governments, a 90-basis-point spread, and no crash. Why?

France today presents a paradox that would have seemed difficult to imagine only a few years ago. The conditions for a crisis are gradually assembling without the crisis itself occurring. A deficit of 5.5% in 2023, 5.8% in 2024 and 5.1% in 2025, according to INSEE; four governments in twenty-four months since the dissolution — Barnier censured, Bayrou brought down over the budget, Lecornu I resigning after twenty-six days, Lecornu II hanging by a thread —; an OAT-Bund spread of around 90 basis points, compared with roughly 55 at the beginning of the year. And yet no open crisis, no capital flight, and €13.5 billion of long-dated OATs successfully auctioned on September 3.

Why this resilience?

Three reasons explain it. All three have their limits.

The first is the euro, because France borrows within a monetary union whose central bank has demonstrated that it can intervene massively against fragmentation. Conditional, certainly, but the safety net exists — not automatically, and certainly not as a permanent substitute for credible fiscal policy. The ECB can prevent a widening interest-rate differential from turning into a fragmentation crisis. Its mandate is not to permanently substitute itself for a state incapable of putting its own finances back in order.

The second reason is size. France is the eurozone’s second-largest economy. An outright crisis in its sovereign debt would not remain French; it would immediately become a euro crisis. It is precisely this systemic dimension that protects Paris, but it also creates a paradox. The larger the debtor, the harder it is to let it fail — and the more violent the collective reaction can become once doubt finally takes hold. No one can exit quickly without hurting everyone else, can they?

The third reason is simpler: France has not yet made an obvious mistake. Truss provided hers in a single press conference. Paris, so far, has avoided the fatal gesture. Its deficits are high but still financed, its governments are fragile but holding, and its budgets eventually get passed — sometimes through Article 49.3.

Markets do not yet demand that France be virtuous. They merely demand that it remain credible.

How fragility becomes a crisis

The question, therefore, is not whether France is fragile — because it unquestionably is. The real question is what could transform that fragility into a crisis.

A first scenario would be a presidential election producing a programme of massive spending without credible financing, at a moment when the ECB had finished easing and had no political reason to shield Paris. A spread persistently above 150 basis points could then fundamentally change the nature of the problem.

A second scenario could come from outside: a U.S. recession, a banking crisis, a new geopolitical escalation, a market shock that would sharply reduce risk appetite precisely when Paris found itself in cohabitation or political paralysis. Markets do not always attack the most vulnerable. Sometimes they attack the most exposed when investors are looking for an exit.

The third scenario is also the least spectacular — and probably the most dangerous: erosion. The spread moves to 100, then 120. Auctions continue to function, but at a slightly higher cost with each new issuance. An additional ten basis points on such a substantial debt stock does not immediately trigger a crisis. Yet as the debt is rolled over, those ten basis points eventually translate into billions in additional annual interest costs. Debt service rises, fiscal room narrows, trade-offs become more painful, and a government hesitates for too long. Then, one morning, the numbers cease to be abstract.

This is how a modern country begins to resemble an emerging market. Not when it becomes poor, nor when its debt reaches some magical threshold, but when a creditor begins to regard the state’s capacity to correct its mistakes as no longer certain.

The dividing line between rich and emerging economies does not disappear when their levels of wealth converge. It vanishes when creditors stop granting them different regimes of trust.

For a long time, advanced economies were allowed to have imperfect public finances provided they could demonstrate institutions strong enough to make correction credible. They were not required to have perfect accounts, but to show that a decision-making mechanism still functioned, that a mistake could be amended, and that a promise had a reasonable chance of being kept.

France still has those institutions.

It has not yet had to demonstrate that they work when markets are truly watching.

It will have that opportunity before the end of the decade.
