Perhaps foreign monetary policy is just more contractionary.
Another explanation is that monetary policy isn't as effective as Sumner et al think. The rabid monetarists are so certain of the power of monetary policy that they find it impossible to even imagine failure. So they claim that it hasn't been tried.
Monetary policy has had 3 years and it has failed miserably. Give up on it!
FX don't say much about domestic policy. Brazil and S. Africa are natural resource rich and commodity prices have been rising rapidly, which would increase demand for those currencies.
And as effem wrote, US policy could be very loose an still be tighter than other countries.
