Analyst: Iron ore at $70 before September

Benchmark 62% iron ore fines at China's Tianjin held steady at $151.90 on Tuesday, not far off 16-month highs.

Iron ore is trading some 75% higher than September when the commodity hit a 3-year low of $87.50 at tonne.

Some analysts point to a possible $170 a tonne by mid year, but further out producers – BHP thinks $85 long term, Fortescue more like $120 – point to softer prices as demand struggle to keep pace with massive new supply coming on stream over the next few years.

But nobody comes close to the bearish predictions from UBS commodity analyst Tom Price.

Price predicts iron ore to fall to $70 – that would be the lowest in four years – in the third quarter 2013 after trading around current levels through June.

Price, who has a solid track record in predicting iron ore prices, told Bloomberg increased domestic production in China and new supply from Australia will see the price cut by more than half:

“The trade will remain pretty tight generally all the way through to June or July and then it starts to fall over going into August or September,” said Price. […]

That will coincide at a time when China has “sufficient” ore and as steel production declines in the second half.

The question of domestic Chinese iron ore supply is a vexing one for the industry.

A price floor of $120 a tonne has become something of a rule of thumb – when prices stay below this level for long enough high cost mines in China become unprofitable leading to cuts in supply.

With a cost curve ranging from as low as $40 a tonne – closer to the margins achieved Australian, Brazilian and South African producers – to as high $140, the predicted $70 would mean most of China's swing producers would be forced to idle mines.

But Melinda Moore, an analyst for Standard Bank, points out the cost reductions which have occurred across China’s bulk mining sector since early 2011 where wages, energy costs, taxes and currency translation rates have fallen:

"All this may be a shock to international miners who are struggling to contain China costs in the face of exorbitant inflationary pressures."

BHP included a graph in its results presentation out last week that shows just how much the cost curve is expected to flatten:
