A Long Way From Midnight: Why Rich-Country Debt Crises Don't Look Like Greece's

The US runs a budget deficit of roughly 6.2% of GDP and a national debt past $40 trillion, yet nothing about its bond market resembles Greece in 2010. The distinction that explains why, monetary sovereignty, also explains what kind of debt problem France, the UK and the US actually have, and why it never produces a single dramatic headline.

The US ran a federal budget deficit of roughly 6.2% of GDP in fiscal 2026, about $2 trillion, and national debt passed $40 trillion earlier this year. By the numbers alone, that sounds like the kind of arithmetic that ends in a crisis. It has not, and according to FT Alphaville editor Robin Wigglesworth, author of the new book "A Fabulous Debt," it is not heading toward the kind of crisis most people picture when they hear the word. The distinction he draws, between an acute debt crisis and a chronic one, is a genuinely useful piece of vocabulary for pricing sovereign risk, and it applies directly to the French bond stress already covered on this page.

Why US Treasuries Set Borrowing Costs Everywhere, Not Just in the US

Wigglesworth's starting point is that US government bonds function as what he calls the molten core of the global financial system. Even a country with sound fiscal policy, his example is the UK, has its own borrowing costs significantly shaped by what US Treasuries are doing, independent of its own fundamentals. The mechanism is simple competition for capital: a lender choosing where to put money, a Norwegian bank deciding whether to extend a mortgage or buy dollar assets, is implicitly weighing that choice against US government debt, because dollar assets are central enough to global finance that they set the floor. A country's own fiscal discipline matters, but it does not fully insulate that country's borrowing costs from decisions made in Washington.

The Distinction That Actually Matters: Acute Versus Chronic

Asked how close the US and its peers are to a sudden reckoning, a spike in borrowing costs forcing immediate spending cuts, Wigglesworth's answer is that they are, in his words, a long way from midnight. His reasoning does not rest on the debt level itself. The relationship between debt size and borrowing costs is weaker than most people assume: yields fell for roughly 40 years even as developed-market debt kept rising. What matters more is whether a country is monetarily sovereign, meaning it borrows in a currency it controls and can, in the last resort, create the money it owes.

The US and UK clearly qualify. France, inside the euro but with the eurozone still jointly controlling its own currency, largely does too. Greece, Argentina and Venezuela do not, which is precisely why those countries get the dramatic version of a debt crisis: a fast, visible blowup once lenders stop extending credit in a currency the government cannot simply create more of. Monetarily sovereign countries have had their own ugly moments, Wigglesworth points to the UK's 2022 gilt market blowup, but those were self-inflicted and technical rather than the kind of acute collapse that ends a currency's credibility overnight.

What Monetarily Sovereign Countries Get Instead

Because the acute version is effectively off the table for a country like the US, the UK or France, what they are exposed to instead is a chronic debt crisis: a slow, multi-decade squeeze in which debt service eats a growing share of the budget every year, with no single moment that forces the issue. Wigglesworth's own framing is that a country can wake up twenty years from now and realize it is spending more on servicing debt than on defense, healthcare, infrastructure and education combined, not because of one crisis, but because the harder political choices were never made along the way. It is a slow drift toward a bad outcome rather than a sudden one, which makes it considerably easier for markets, and voters, to ignore until the share of the budget consumed by interest payments is already large.

France in This Framework

Applied to France specifically, the distinction is clarifying. France's bond crisis, covered in an earlier piece on this page, where roughly €215 billion of French investment-grade corporate debt, 38% of that market, now trades at lower yields than French government debt of similar maturity, is not evidence that France is becoming Greece. Wigglesworth's own description is blunt: France is not Iraq. What it is, in his telling, is a country somewhere in the foothills, or possibly the later stages, of the slow structural squeeze that chronic debt dynamics produce, a primary deficit that has not been closed in any year since 2002, a political system that has repeatedly failed to agree on the spending or tax changes that would close it, and a market that has started pricing the accumulated effect of that failure rather than any single new event.

What Leverage Bond Markets Actually Have

Bond markets cannot force a government to change policy directly. What they can do, in Wigglesworth's framing, is charge more for the privilege of continuing to borrow, or eventually stop lending altogether, which is the only real discipline available to a lender rather than a regulator. A government can partially resist that discipline for a while through legal compulsion, requiring domestic banks or pension funds to hold more of its own debt, but that tool has limits, and pushed too far it tends to provoke exactly the repricing it was meant to avoid. Norway is the rare exception: a country with essentially no need to borrow from markets at all, which means markets have almost no leverage over it. The US, UK and France are not in that position. They depend on continued lending, which is the quiet source of whatever discipline their bond markets are currently applying.

What This Means for a Portfolio Pricing a "Sudden" Crisis That Isn't Coming

The practical allocator mistake this framework corrects is treating developed-market sovereign risk as a binary, fine until it suddenly is not, modeled on the Greek or Argentine playbook. For a monetarily sovereign borrower, that specific failure mode is not the one in front of a portfolio. The real exposure is the slow, compounding one: debt service claiming a larger share of the budget every year, crowding out other spending, and eventually crowding into the same pool of global savings now also funding hyperscaler debt and an AI capital expenditure boom running close to $800 billion annually, a dynamic covered elsewhere on this page. Pricing that risk as a tail event that either happens or does not misses the mechanism entirely. It is already happening, gradually, in the data every one of these countries publishes every year. The question worth asking is not whether a monetarily sovereign government has a debt crisis coming. It is how far into the chronic version of one it already is, and how much of a budget, or a portfolio, is being quietly reallocated to interest payments before anyone calls it a crisis at all.
