The Cartography of the Risk-Free Rate

Interest rates are the price of sovereign money, and that price is increasingly set by geography rather than by the policy rate. This paper extends the geography-first thesis of From Geology to Geography from commodities to the term structure of interest rates. The long end of the world's sovereign curves has migrated from an expectations-first regime, in which the ten-year yield forecast the average future policy rate plus a small and stable term premium, to a fragmentation-first regime, in which the term premium, the inflation-risk premium, and the dispersion of sovereign spreads carry a persistent and rising geopolitical charge. The investment implication is dispersion, not direction. This is not a call on the level of the ten-year yield; what has structurally repriced is the compensation investors demand for holding duration.

Three facts frame a single repricing. The term premium has exited the 2014-to-2021 regime, with the ACM ten-year term premium estimate near 0.6% in May 2026, accounting for more than half the recent rise in yields. The price-insensitive official buyer that anchored the Treasury market is retreating; China's holdings, for example, have fallen to $652.3 billion, the lowest since September 2008. And the equity-bond correlation that made government bonds a portfolio hedge has inverted, averaging near +0.6 since 2022. The risk-compensation component of interest rates is doing the work, the marginal price-setter has shifted from a price-insensitive official buyer to a return-sensitive private one, and duration now amplifies equity drawdowns when the shock is supply-side.

The intellectual lineage of this thesis runs from weaponized interdependence to the 2022 freeze of two-thirds of Russia's central-bank reserves, which converted reserve assets from negligible-credit-risk instruments into confiscation-risk instruments. The revealed preference of the official buyer is now gold: central banks have bought more than 1,000 tonnes annually for four years, lifting gold's reserve share above 23%. We sit between the de-dollarization camp and the dismissers. The dollar will not be dethroned, no liquid substitute exists at scale, and most of the reserve-share decline is valuation rather than reallocation. But the term premium is set at the margin, and the marginal reserve manager has ever more reason to diversify.

Fragmentation enters the curve through four channels: the term premium, the inflation-risk premium that links the rate regime to commodity supply shocks, the withdrawal of the official bid, and the fiscal-credibility channel that disperses sovereign spreads. The euro area is just one laboratory; the market now prices sovereigns on credibility rather than geography, tightening Italy while widening France. US fiscal arithmetic is another, with the interest bill self-reinforcing, pushes the premium higher before any geopolitical shock.

For a real-asset portfolio, the duration ballast is no longer reliable, the real risk-free rate is structurally higher, sovereign dispersion is an opportunity, and the inflation-risk premium specifically rewards real assets. We assign roughly a one-third probability that the shift proves cyclical. The more likely path is that the price-insensitive buyer has left the building, and the risk-free rate is now a variable with a widening distribution.
