COLUMN-The price is right; the ultimate copper buyer is back: Andy Home

LONDON, April 28 (Reuters) - It’s been a while but the ultimate copper buyer is back in town.

China’s State Reserves Bureau (SRB), which manages the country’s strategic commodity stockpile, has just skimmed a couple of hundred thousand tonnes from the mountain of copper sitting in Shanghai’s bonded warehouse zone.

As ever with this secretive entity, it’s difficult to pin down exactly the volumes involved but there’s no doubt that the SRB is back in the buying seat and back in a big way.

That has all sorts of implications for market balance this year and says a lot about what the world’s most powerful copper buyer thinks about the current price.


The first question, as ever with an entity that takes such care to conceal its movements in the market, is what exactly has the SRB been doing.

The current programme seems to have three distinct components.

The first, and the one that triggered last week’s headlines, was a raid on the Shanghai bonded warehouse zone when the copper price collapsed to a near four-year low of $6,321 per tonne around the middle of last month.

The bureau is thought to have bought at least 200,000 tonnes and up to as much as 350,000 tonnes from banks that had metal on their books from expiring finance deals.

This appears to have been an opportunistic move to capitalise on low outright price and on low physical premiums, the latter resulting from the accelerated build in bonded warehouse stocks in the early months of this year.

The Shanghai swoop is in addition to a purchase in January of around 300,000 tonnes of metal in the form of term contracts.

Offsetting these two streams of buying will be an expected sale of around 200,000 tonnes of older stock some time later this year, part of the SRB’s “normal” stocks-rotation scheme.

The best estimate, therefore, is that the SRB will be a net buyer of around 300,000 tonnes this year, albeit with the potential to add more against its 2015 budget target if the price is right.

It may well have been a buyer last year as well, although there is a strong suspicion that the SRB was merely mediating the purchase of metal, both copper and nickel, for a Chinese military agency.


Quite evidently, the physical purchase of around 300,000 tonnes of copper has significant implications for commercial market balance this year.

The current analyst consensus is that this will be a year of surplus as last year’s surge in mine production cascades down the supply chain into the refined market.

But the surplus is not expected to be overwhelming.

The most recent Reuters quarterly poll of analysts yielded a median expectation that copper would be in surplus to the tune of 228,000 tonnes this year. MKTBAL-ACL

The full range of estimates from the 16 analysts who submitted a 2014 market balance estimate runs from a deficit of 90,000 tonnes to a surplus of 519,000 tonnes.

These are marginal outcomes in a 20-million-tonne global marketplace and allow for little statistical cushion against the physical removal from circulation of around 300,000 tonnes of metal.

Moreover, analysts are steadily trimming their surplus estimates. The median expectation in the previous quarterly poll in January, for example, was a 2014 market surplus of 260,500 tonnes.

This represents a collective reassessment of likely mine supply growth this year after the 8 percent jump seen in 2013.

Supply disruption to existing operations is back in focus after a surprisingly uneventful year by copper’s standards.

Freeport McMoRan has already had to “defer”, to use its word, around 125 million pounds (56,700 tonnes) of production at its Grasberg mine in Indonesia due to a change in the export tax regime.

It and fellow Indonesian copper miner Newmont Mining are officially upbeat that a deal will be reached soon, allowing for a return to normal production rates. But every week without one means more copper lost, or “deferred”.

Secondly, last year’s supply surge largely came from brownfield expansions. This year’s will come from new mines with a higher risk of start-up problems, already foreshadowed with guidance downgrades and timeline delays at mines such as Oyu Tolgoi in Mongolia and Caserones in Chile .

This year’s surplus, in other words, is a shrinking target and while the siphoning of several hundred thousand tonnes into strategic stocks doesn’t alter the underlying production-usage numbers, it has the capacity to affect commercial market balance, the amount of metal available at any one time.


That is a decidedly bullish development, as is the implicit price marker just placed by the Chinese government.

The last time the SRB entered the copper market in a big way came in 2009, when it was incentivised by the post-crisis collapse in the copper price to below $3,000 per tonne.

The fact that it evidently now regards a price below $7,000 as an entry point says a lot about how much the copper market has evolved in the last few years.

They have been years of rapid cost inflation, lifting the cost curve to the point that analysts at Macquarie Bank now estimate 10 percent of Chinese mine production “should be unprofitable at prices of $6,800 per tonne or less”. (“Commodities Comment”, April 15, 2014)

Moreover, the pipeline of new supply has been significantly diminished by the combination of lower prices and the new shareholder-mandated austerity among the world’s biggest natural resource companies.

Beyond the next year or so, and the exact timing is still a topic of hot debate, the copper market is widely expected to revert to a chronic production shortfall with all the bullish price implications you’d expect from such an assessment.

The SRB’s stepped-up activities in the copper market this year strongly endorse such a view. Of course, the bureau’s decision to pull the buy trigger renders such a bullish outlook partly self-fulfilling.

The world’s most powerful copper buyer, after all, has just told us where it thinks the medium-term price floor is in this market.
