Bond investors want to be paid for waiting again

For more than a decade, the international bond market operated under a state of financial repression so profound that investors routinely accepted negative real returns for the privilege of parking capital in sovereign paper. The concept of the term premium—the excess compensation an investor demands for bearing the duration risk of a ten-year bond over rolling short-term bills—vanished from institutional vocabulary. In an era of quantitative easing and explicit forward guidance, duration was treated as a riskless attribute. In late October 2022, as the benchmark ten-year US Treasury yield surges through 4.25 per cent, that institutional complacency has been forcefully retired. Bond investors want to be paid for waiting again.

The sudden resurgence in long-dated sovereign yields cannot be explained entirely by shifting expectations for the federal funds rate. While the front end of the curve has aggressively priced in a higher terminal rate, the steepening at the back end reflects a deeper, structural shift in the term premium. When decomposed using classical affine term structure models, such as the Adrian-Crump-Moench framework operated by the New York Fed, the recent climb in yields reveals that duration risk is being aggressively repriced across global portfolios.

Model Decompositions

An affine term structure model separates a ten-year yield into two distinct economic components: the expected path of short-term policy rates over the coming decade, and the term premium demanded by investors to compensate for inflation uncertainty, supply imbalances, and volatility. Throughout 2020 and 2021, the estimated term premium on ten-year Treasuries hovered in deeply negative territory, sinking as low as negative 100 basis points. Investors were effectively paying the US Treasury for the convenience of holding duration.

Today, that term premium is rapidly clawing its way back toward positive territory. Several structural forces are driving this recalculation. First, inflation volatility has shattered the perceived hedging property of government bonds. For twenty years, fixed-income allocations served as an automatic hedge against equity sell-offs, operating on a negative stock-bond correlation. In 2022, as inflation shocks simultaneously depress equity multiples and sovereign bond prices, that correlation has turned sharply positive, destroying the classic 60/40 portfolio and demanding an explicit volatility surcharge on duration.

Supply and Absorption

Second, the supply-demand balance for sovereign paper has suffered a structural breakdown. The Federal Reserve, previously the most price-insensitive buyer in the market, is actively reducing its balance sheet through quantitative tightening, allowing up to $60 billion in Treasuries to roll off each month. At the same time, the primary foreign buyers of US sovereign debt—foreign central banks—are stepping back, with Japan actively selling Treasuries to fund foreign exchange interventions and commercial banks nursing massive unrealised securities losses that preclude additional duration purchases.

With traditional price-insensitive buyers in retreat, the marginal Treasury note must be cleared by private institutional asset managers and hedge funds. These buyers are acutely sensitive to capital costs and financing spreads. They will not absorb hundred-billion-dollar monthly refunding packages out of civic duty; they require a wide term premium to protect against future interest-rate volatility and sovereign deficit expansions.

The return of the term premium represents a permanent increase in the hurdle rate of global capital. When long-term risk-free rates command a positive risk premium, every downstream asset class—from commercial real estate to corporate credit—must adjust its discount rate accordingly. Ten-year Treasuries paying north of 4 per cent are not an anomaly; they are the restoration of historical reality in a world where waiting for your money finally carries a cost.
