Pay careful attention to the divergence between the
"Euro PHLX" line and the "Gold (EOD)" line,
from the start of 2009 on (just for one example)
Plus also the remarkable general correlation between the Gold, Brent crude, CRB and Euro lines —aside from those times when the Gold line markedly diverges from the trend of all the others, only to see them follow the direction of gold after a brief period of adjustment to a new reality.
It almost looks like someone is adjusting the relative value of gold in terms of euros (and therefore by extention in terms of dollars as well), and this revaluation of gold is then guiding a revaluation of all other commodities, starting with oil (which is a significant input cost factored into all other commerce).
Do you think it is possible there could be a tighter relationship between the value of oil and gold, than between oil and currencies? And that gold is used to devalue currencies, thereby avoiding a sustained deflation. Which is what causes a fall into, and inability to escape from, a Depression.
Interesting, no?
And here is something else that is interesting, if you are looking for additional homework credit while looking at the data in the graph for yourself (a link to the interactive version of this graph is provided in a comment below BTW). Not only can you see evidence that gold is being used to devalue currencies against the golden reference point of value when general commodity prices are falling, but there is also evidence to support the case gold is being use to up-value currencies during times of runaway inflation too. Pretty neat, huh?
Marked-to-Market gold at the ECB, in action!
Gold prices the dollar euro, and the dollar euro prices everything else.
