something I never understood

back when there was the GFC in 2008 I wondered why the USD went higher and the Australian Dollar (which was less exposed) took a hammering?

Seen in context here some years later it still seems odd

that the EURO continued to slide against  the USD after 2009 makes sense to me.

I notice that the Australian dollar is now more or less back on track to the rate of change it would seem to have been on before the GFC.

People say the AUD is overvalued, perhaps it is ... but isn't the USD too?
