Whilst my grasp of macro economics is about as good as Tony Abbotts grasp of evolution I do know that to have a mining boom you need two things and two thing only. Rising commodity prices and a booming customer. Everything is superfluous to the equation and can be discarded.
This is the Shanghai Composite.
These are basic metal prices over the past month.
Finally the S&P300 Metals and Mining.
Seems like the market knows something that neither the economists or our politicians know.
