Yeah, there's a ton of US$ cash outside of USA. Estimates have been between 40 and 72% https://www.bullionstar.com/blogs/jp-koning/how-much-u-s-currency-is-held-overseas/ https://www.bullionstar.com/blogs/jp-koning/how-much-u-s-cur... Swiss Francs are far from a reserve currency, beyond the poor recognition of the notes outside of Switzerland and nearby countries, so I'm doubting too many are held outside of Switzerland. Euros or Dollars would be far better.
