Why are commodity prices falling?

[Simfan34]

I have my own opinions, but I'd like to hear everyone else's theories.

In short: falling demand from China and a rising dollar.

The sad thing is this would be the perfect opportunity for us to pour money into infrastructure investments with such low commodity prices. But, of course, we're doing no such thing. And African economies dependent on exports to China and cheap credit from that country would have missed an opportunity to painlessly restructure and instead find themselves in hard times.

The end of the Fed's QE plays a role here, no?

Which has led to the rising dollar, yes.
