It's pretty cute of the Fed to throw around the word reserves. A brilliant bit of propaganda instituted by Powell to start. It may fool most people but Kashnkari knows that reserves are cash. Money. Everyone on a basic level knows the difference between a financial piece of paper, figuratively, and money.
Kashnkari, or someone like him is going to be the next chairman, even if a Democrat appoints him. There is zero political opposition to stupendous monetary expansion. None, Not anywhere in the world
