"All I see is two uncorrelated graphs that happen to be upward trending at the same time."
Hehe! That's called visual correlation.
I think you've got something there on the currency vs. commodity plot but why choose the Aussie USD cross? The EURUSD or DX vs. DBC would likely give you what you want in Dollar decline vs. Commodity rise.
That's helps prove the point of my plot since the Fed actions have directly caused the dollar decline.
