The spike today (in gold) was also present in the EUR and GBP i.e. it was more a USD-related thing. However, gold went up more in proportion as far as I can see. So, what was it? Was it China dumping some USD cash to buy gold??
Not sure about this , Magpie.
A function that looks exponential in a log-chart is e.g. exp(exp(x)). I would not call this exp-squared. "Exp-squared" would make me think of [exp(x)]^2 = exp(2x) or, maybe, exp(x^2) instead.
Anyway, I doubt there is official nomenclatura on this. Re-iterated exponential function would possibly do it.
No, it's not. It's just a sign that no one trusts the collateral, since it is some shady version of paper gold traded on the CRIMEX,
It's completely rational, you want the gold NOW and DELIVERED, and not in the future and promised on paper.
