No, not the one that you think. Not thermo nuclear war(although we recently discussed that a small chance of error or miscalculation could accidentally lead to the destruction of the planet.) I am talking about the economic nuclear option that we have pretty much brought upon ourselves. The sanctions and other steps we have taken against Russia will leave them with no choice, to survive, than backing the Ruble with gold. If and when they do so, if China does likewise with the Yuan, it is game over for the US dollar as the world’s Single Reserve currency. I believe that was what Fed Chair Powell was hinting at this week when he said there was room for multiple Reserve currencies. He was talking about crypto but that was because he couldn’t suggest a gold backed sovereign currency, because he knows that would soon overtake the US dollar supremacy that has existed for more than 100 years. We could actually have multiple reserve currencies if they were on a relatively equal footing. Having one or two backed by gold would trump any other, no matter how once powerful the economy and military behind it was. We all have known that eventually fiat currencies fail. We just didn’t know when and what would be the specfic time and circumstances to bring it about. It probably isn’t something that will be a pleasant experience, but we are living during an historic period of time.
