Is China looking for a new "Copper Standard"?

From the UK Telegraph:

Hard money enthusiasts have long watched for signs that China is switching its foreign reserves from US Treasury bonds into gold bullion. They may have been eyeing the wrong metal.

China's State Reserves Bureau (SRB) has instead been buying copper and other industrial metals over recent months on a scale that appears to go beyond the usual rebuilding of stocks for commercial reasons.

Nobu Su, head of Taiwan's TMT group, which ships commodities to China, said Beijing is trying to extricate itself from dollar dependency as fast as it can.

"China has woken up. The West is a black hole with all this money being printed. The Chinese are buying raw materials because it is a much better way to use their $1.9 trillion of reserves. They get ten times the impact, and can cover their infrastructure for 50 years."

One thing is clear: Beijing suspects that the US Federal Reserve is engineering a covert default on America's debt by printing money. Premier Wen Jiabao issued a blunt warning last month that China was tiring of US bonds. "We have lent a huge amount of money to the US, so of course we are concerned about the safety of our assets," he said. [emphasis added]

This is slightly disingenuous. China has the world's largest reserves - $1.95 trillion, mostly in dollars - because it has been holding down the yuan to boost exports. This mercantilist strategy has reached its limits.

The beauty of recycling China's surplus into metals instead of US bonds is that it kills so many birds with one stone: it stops the yuan rising, without provoking complaints of currency manipulation by Washington; metals are easily stored in warehouses, unlike oil; the holdings are likely to rise in value over time since the earth's crust is gradually depleting its accessible ores. Above all, such a policy safeguards China's industrial revolution, while the West may one day face a supply crisis. ...
