In this article here, http://www.telegraph.co.uk/investing/gold/gold-resurgence-whos-buying-gold-and-why/ , it states that "gold tends to do....best when markets lose faith in central banking".
I understand that gold does well when other assets do badly as it acts as a store of wealth, but I cannot understand why it does well when markets lose faith in central banking. I can see that if central banking isnt working markets are probably doing badly, but the quote seems to imply a deeper and more direct connection.
Also can someone think of a historical example when this happened.
