The Fed has become largely irrelevant as the Treasury assumes control over monetary-fiscal policy and yield curve management.
Too little corroboration in the last 3 days to call a trend (1 article). Watching for it to gain traction.
Some market observers argue that the Treasury Department has effectively assumed control over monetary and fiscal policy coordination, including yield curve management, rendering the Federal Reserve increasingly irrelevant in its traditional role as the primary architect of monetary policy.
If fiscal authorities gain effective control over yield curve outcomes, the traditional transmission mechanisms of monetary policy become distorted, and investors lose the ability to rely on Fed actions as a reliable driver of bond market moves, increasing uncertainty around the true cost of capital.
"Also, in doing so, it has usurped some of the powers of the Fed, making the Fed even more irrelevant, since if it issues more T-Bills to finance the purchase of the bonds, T-Bill yields will go up, and the Fed will have to either (1) raise rates to match the higher T-Bill yield, or (2) buy those T-Bills to keep rates where they are."
