Is Dr. Aluminum Taking Over Dr. Copper’s Practice?

For many years now, investors have turned to ‘Doctor Copper’ for an indication as to the health of the global economy. The red metal is used in everything from construction to kitchenware, and so it’s seen as a pretty accurate indicator of economic health.

But some argue copper’s lost its mojo.

Eugen Weinberg, head of commodity research at Commerzbank, told the Wall Street Journal’s Moneybeat blog that all the red metal tells us about is the state of some large emerging markets, and, more specifically, China. It may even be in danger of going the way of the Baltic Freight Index – a previous barometer for trade activity based on transportation rates that has fallen out of favor (and was replaced by the Baltic Dry Index).

Aluminum, they say, may now be a better consultant.

“Copper’s relative position has deteriorated,” said Stephen Briggs, a base metals analyst at BNP Paribas. “Yes, it’s used in lots of different things, but … aluminum is [also] used widely.”

The aluminum market in more than twice the size of the copper market, and more than 50 million metric tons are produced every year, compared to 20 million tons of copper that is produced each year. It’s also used in a similarly vast range of products – from cans to cars.

On the downside, aluminum is more closely tied to oil and energy prices, because energy accounts for 40% of the cost of production. And critics say that distortions in the market, such as the high extra fee of getting the physical metal delivered, mean its thermometer isn’t better than copper’s.
