The SMH has a nice chart today:
My view of gold (I traded it successfully for some years), is that it is primarily the undollar, the natural hedge against the reserve currency (or unyuan if that eventuates). As such it’s primary driver of valuation is that of its partner currency.
In turn, that value derives not just from the raw price of the reserve, but from the many variables that make the pricing context: monetary, fiscal, strategic etc. Thus there is no one-to-one correlation between any given metric – price, money supply, fiscal balance, power position – and gold. The price is a judgement of relative stability or chaos of the sum total the variables underpinning the reserve.
