It really doesn’t. The Federal Reserve’s gold vault is in New York, not Fort Knox, and it’s separate from the U.S. Treasury’s holdings. This thread started about foreign gold held at the Fed, Germany and Italy’s reserves, not U.S. sovereign gold in Kentucky. Mixing those up is like arguing about your neighbor’s bank account while waving around your mattress stash. Different institutions, different controls, different issues.
Or while you are at it provide some evidence to your conspiracy theory.
Modern banking and finance, not just in the US, relies on fractional reserves. This is not a movie.
