AUD falls to 70c ..if RBA lower rates by 1/4% on a crappy economy outlook., page-55

$150 billion worth of commodities stocks sell off indicates the market doesn't agree with your reasoning.

Commodity prices will fall faster than the Aud and any profits will be wiped out for mid cap producers.
FMG will go down in history as the biggest rise and fall of a commodity stock. It will not be able to compete.

So for some reason you think you can get the Aud down before its too late?
You already concede there will be a point of failure. Interesting contradiction.

The reserve bank has no power to control commodity prices falling below marginal cost even with an exchange of .70usd therefore you economic theory is false.

Your reasoning is totally against the movement of the market.

Where did you go to school and where did you study economics?
