It seems as though the endgame to all of the political chaos we are experiencing in the US is the dethroning of the dollar as the world’s reserve currency. Putting aside for the moment the question of why or whom might benefit from such an outcome, what is the best way to play defense if your wealth is dollar-denominated?
You can invest in foreign funds, but some of them are US currency hedged to help reduce the effect of the exchange rate(s) which will somewhat counter what you’re trying to do. I don’t know much about this, but keep it in mind when researching funds, especially foreign bond funds.
