The argument that US Treasuries remain the world's indispensable safe asset is correct and increasingly fragile. Three threads in this dossier — the structural erosion of Treasury demand, a budget deficit without peacetime precedent outside recession, and a theoretical result drawn from an obscure class of French growth-linked bonds — converge on a single uncomfortable claim: the price the United States pays for fiscal dominance is rising, and the mechanism by which it gets paid is more likely to be inflation than default.
Start with the plumbing. According to The Economist, the most dependable holders of US debt — banks, foreign central banks, and the Federal Reserve itself — now own less than a third of the Treasury market, the lowest share in three decades. The marginal buyer is increasingly a leveraged, yield-seeking private investor. That is the same buyer base that vanished in March 2020, when private demand for Treasuries dried up overnight and the Fed was forced to intercede. The safe asset has not stopped being safe; its market microstructure has stopped being boring.
That $300bn is the exorbitant privilege, quantified. It is also the prize at risk if the franchise is mismanaged. The Economist's survey of alternatives is brutal and, we think, correct: euro-area bonds trade like the paper of a supranational without taxing power; European Commission issuance behaves the same way; China cannot offer a genuinely liquid international safe asset because capital controls would trap foreign money in a crisis — and The Economist puts non-trivial odds on Beijing actually closing the capital account in a systemic episode. Gold is a store of value, not a funding instrument. There is no successor. There is only degradation of the incumbent.
Who's going to buy the bonds? They were all forced through financial repression into the hands of rational accounting man and they're all underwater on them.
The French bond clue
Here the dossier offers something unusual: a clean empirical handle on a question normally lost in theory. Stavros Panageas, working from a historical episode of French sovereign bonds indexed to aggregate growth, argues that the risk-adjusted growth rate — growth measured under the risk-neutral measure (the probability weighting used to price assets) — exceeds the risk-free rate. The technical punchline matters: when risk-adjusted growth sits above the risk-free rate, a sovereign can in principle roll debt forever without running primary surpluses. Panageas also dismantles the standard objection that finitely-valued, cointegrated assets prove the aggregate endowment must itself be finite. It is a permission slip for fiscal dominance, written in the language of asset pricing.
Combine the strands. A 6%-of-GDP deficit with no peacetime parallel outside deep recession, per The Economist. A theoretical case that rollover without surpluses is feasible. A buyer base that is structurally thinner and more reflexive. And a Social Security trust fund the same publication expects to deplete within six years. The path of least political resistance is not default; it is inflation that erodes the real value of the stock while nominal coupons clear. Quoth the Raven frames the binary starkly — soft default via inflation or hard default via crisis — and assigns higher likelihood to the former while noting that a true Treasury crisis remains low-probability precisely because the system is built around the assumption that it cannot happen. We share that ordering.
The operationalisable claims in the dossier lean one way. The Economist puts YES on Treasuries exceeding $50trn within a decade of June 2026, YES on Social Security depletion inside six years, and YES on Chinese capital-account closure in a systemic crisis. Kevin Warsh's stated intention to shrink the Fed's Treasury holdings adds a further tightening vector. No dissenting forecaster appears in the cluster; readers should treat this as a one-sided dossier on direction, with genuine disagreement only on the mechanism — inflation grind, intervention-managed wobble, or genuine break. The Bank of England's 2022 gilt operation, which The Economist holds up as a model — aggressive purchases, rapid exit, profit booked — is the template policymakers will reach for. It worked once. It is not a strategy.
