Financial market reports suggest that there are uncertainties about the Federal Reserve's ability to absorb new US Treasury Bonds issued in larger quantities to support the US government's growing budgetary requirements (i.e. the pandemic support of the economy).
This hypothesis is bolstered by the example of 2018:
...real yields rose and stocks and corporate bonds got clobbered until the FED reversed its tapering exercise and started buying USTs in size.
- Why can't the Treasury and the Federal Reserve agree upon a controlled issuance and instant procurement of UST bonds "straight from the printing press"?
- Why subject the market to the ambiguity of being able to partake in this exercise, which is specifically aimed at funding the budget through the Fed's resources?
