If the current ~4.5% average yield curve rate propagates to all $31 trillion worth of debt, we are looking at $1.4 trillion per year just in interest payments. This would be 29% of the 2022 FY total Federal tax receipt.

Poster Comment:

$1.412 trillion would be double the current $706 billion. But that burden would be met by money printing which would require higher interest rates to compensate for the added inflation.
