Here are the highlights of Randy Wray’s great article about the commodity bubble (full article at Naked Capitalism):
Take the top 33 commodities that are globally traded—everything from gold and oil to to rubber, flaxseed, jute, plywood, and something called diammonium phosphate. Over the past 110 years, an index price of these 33 commodities has declined at an annual rate of 1.2% per year. Although demand for these 33 commodities has increased a lot over the century, new production techniques plus successful exploration has resulted in a declining price trend.
Further—and this is a bit surprising—deviations from the trend follow a normal distribution (you learned about this in high school; it is a bell curve with nice properties; chief among these is the finding that about 68% of outcomes fall within one standard deviation; about 95% fall within two standard deviations (once a generation); and you’ve got just about a snowball’s chance in hell of finding outcomes that are three or four standard deviations from the mean).
But what is more surprising is that over the past decade, the price rises you find for these 33 commodities are just about beyond the realm of possibility—2, 3, and 4 standard deviations away from trend. It is a boom without any precedent. Quite simply, nothing even close has ever happened before, in any market, including hi tech bubbles and real estate bubbles.
Now, to be sure, the whole thing is going to blow up, in what Frank Veneroso calls a commodities nuclear winter. As prices rise, consumption of the commodities falls (as we are already observing) both through substitution and through conservation. At the same time, additional supplies come on line. Real world suppliers feel the imperative to slash prices to have some actual real world sales. They cannot forever live in never-never land with rising prices and collapsing sales.
There are many shoes that will drop, bringing back the Global Financial Crisis with a vengeance. Commodities crash, default by a Euro periphery nation, failure of a Euro bank, or the closure of Bank of America or Citi. All of these are likely events, less than one standard deviation from the mean; probably all of them will happen within the next year.
No matter what the triggering event is, that commodities nuclear winter will happen.
