Suppose several countries dump their T bills at once.
Then what?

How much of the US National Debt is held by the FED?

As of recent data, the Federal Reserve holds approximately 20-25% of the US national debt, primarily in the form of U.S. Treasury securities it has purchased through its open market operations. This percentage can fluctuate over time due to changes in monetary policy and market conditions. For the most current and precise figures, you can refer to the Federal Reserve’s weekly H.4.1 release or the U.S. Treasury’s reports.

What would be effect of the fed holding 75% of the US national debt, and another 25% by US citizens as the daily cash float of the US stock market?

I do not see the downside as the rest of the world economy is peered up against the US machine.
