While the US Treasury can temporarily influence long-end yields through buybacks and bill issuance, it cannot permanently fight global capital markets in a new macroeconomic regime. Long-end yields and term premia will ultimately be determined by procyclical fiscal impulses, negative supply shocks, and Fed monetary policy resolve.

Key Takeaways

  • 1.Treasury debt management tactics, such as terming in with bills and long-end buybacks, can only have a temporary impact on yields before relative-value equilibrating mechanisms and global capital flows reassert fundamental pricing.
  • 2.Long-end Treasury yield increases primarily reflect a new macroeconomic regime characterized by procyclical fiscal policy, negative supply/energy shocks, and positive bond-equity correlations, which elevate term premia.
  • 3.The ultimate shape of the yield curve depends on the Federal Reserve; failure by the Fed to signal resolve against inflation risks long-end yield spikes and US dollar weakness.
