Long bonds are selling off for a new reason

A profound shift has occurred in the sovereign debt market. Throughout 2022 and early 2023, bond yields rose because markets were pricing in higher Federal Reserve policy rates. Today, however, the sell-off in long-dated US Treasuries is driven by an entirely different catalyst: an avalanche of sovereign debt issuance colliding with price-sensitive private buyers. The ten-year yield has pierced 4.55 per cent, touching sixteen-year highs.

The Supply-Driven Bear Steepening

With the federal deficit ballooning to $2 trillion and the Fed continuing to shed its bond portfolio via quantitative tightening, the supply-demand balance for sovereign duration has permanently broken down. Traditional non-economic buyers—foreign central banks and domestic commercial lenders—have stepped back, forcing yields higher to entice hedge funds and asset allocators. The bond vigilantes are pricing duration risk rather than monetary policy.

The sovereign bond market is no longer reacting to central bank interest rate forecasts; it is actively revolting against the relentless, unconstrained supply of government paper.
