I think this is very important and also interesting. Fed lowered interest rates and bond yields have gone in the opposite direction. Could people be losing faith in the U.S. bonds? This results in a higher burden for the U.S. debt payments. If people lose faith in our ability to pay off bonds, or get concerned that we'll "print" our way out of our debt problem, that will result in a significant crisis.
BTW, neither candidate is really addressing our debt problem, but it will definitely get way worse under Trump than Harris, if they both stand by their words and get their ways.
