Commodities, Currencies and Equities - What gives?

I've talked about  divergences in commodities, currencies and equities since February because i've been noticing markets have not followed usual correlation trends. Here are some charts that I've been following for some time. Not sure if this is setting a long term trend change in correlations across markets or its a short term anomaly. My intuition says its the later since drop in commodity prices especially Copper since its usually a good leading indicator for macroeconomic growth.
