price forecast $15 to $22 ton, page-6

Not sure of the point of this post.

We can't unwind historical inflation that already occurred ages ago (because of what "should have" occurred - in some alternative universe of ideological "should have").

At one stage when I was bullish on FMG and Roger Montgomery supporters were re-offering his bearish predictions I updated the old iron ore prices with the actual inflation rates using 2015 as the baseline. The tools to do that are readily available on (or even in) google.

To get a price of $21 USD a ton, today, you'd need to put in some nonsense inflation assumptions. Like putting 2% a year on ancient data.

Sure prices can temporarily dip below cost of production. But the key word is temporarily.

Garbage modelling assumptions in, will always produce garbage predictions coming out. Nothing personal against you - just your argument that concludes "today's price should be around $21 ton".
