I was going by foreign currency reserves, which feature CAD and AUD in much greater quantities than CHF. Also I swapped in SGD for GBP, whoops.

Global reserves continue to hold USD in greater quantities than anything else. A movement away from the USD still means a relative loss of faith in the US. If there's nobody who can guarantee trade then you still need to hold reserves, right? You just have to hold a broad and shallow pool rather than going deep on one currency.
