The issuance of bonds continues to this day due to Congressional mandate. In reality, our bond market funds nothing and serves only as a reserve drain which helps the Fed maintain its overnight target interest rate. It has nothing to do with funding the government. When the US government wants to spend money they do not call China and ask for a line of credit. They do not count tax receipts. And they most certainly do not call the Fed to ensure that we have any money left. No, the truth is that the USA never really has nor doesn’t have any money. So the entire implication that the Fed is helping to fund US government expenditures is entirely inaccurate and anyone who implies as much is still working under the now defunct gold standard model and clearly doesn’t understand the workings of the modern monetary system.
