Two years ago I examined the history of commodity prices just as the peak in the CRB raw materials index was being reached. I had the following highlights and questions at that time:
1. The cyclical history of commodity prices placed August 2008 in the middle of the time window when a new minimum should occur, and we were at an all-time high. (In less than a year we reached a new minimum.)
2. The inflation adjusted value of the index was in a region not seen since the high inflation period of the 1970s.
3. One implication was that commodities could drive a new inflationary cycle. (We all know that just the opposite has happened so far.)
4. A question was asked: Could commodities enter a new range of prices that would replicate the inflation adjusted values seen in the 1970s?
5. The inflation adjusted value of the CRB index had a declining trend line for over half a century. Could we reach an inflection point where the real CRB index could start to rise?
See the following graph from the 2008 article as you review the above points and questions:
Today David Rosenberg, chief economist for Gluskin Sheff in Toronto, posted an updated version of a graph I had on my 2008 article:
What is not shown is the time period prior to 1972 where the 20-year average for the CRB index averaged around 115 compared to the 1974-2007 average around 280. This is shown in the following graph from the 2008 article:
Rosenberg points out that the top of the 25-year range ending in 2007 proved to be the support level for the 2009 minimum. If this support holds at the next minimum, the new normal for commodities may be in a higher price range than existed previously. That is in contrast to what many feel the new normal will be for other economic factors: lower employment levels, lower real personal incomes, lower GDP growth rates.
Commodities could have a new normal, mirroring debt, with both going higher.
The transition from the post WW II stable era for commodities to the era of the late 70s into the 21st century occurred at the end of a low interest, low inflation era. An apparent trigger for the transition was the major bear market in stocks (bottom in 1974), an oil price shock and the serious recession of 1973-75. The permanence of the new range for CRB was anchored by the inflationary period of the late 1970s to early 1980s.
If the new normal for commodities is to trade in a higher price range, both in nominal and real terms, it will have been triggered by similar events in the 2000s: a long period of low inflation and interest rates followed by a major bear market for stocks, an oil price shock and the Great Recession.
We will see in the coming years if an inflationary period, which may have been a critical anchor for higher nominal commodity prices (and a bubble in real terms) in the 1970s, is really necessary to fix a higher trading range for commodities. If not, an alternative anchor could be a shift to higher aggregate demand without a compensating increase in supply. This would fall into the theory of limits of sustainable resource harvest from the planet.
An unmet higher aggregate demand model could lead to a change in the trend going forward and we could face an increase of real commodity prices over time. This would reverse the declining real commodity price trend of the last 65 years. This could occur in the absence of more general inflation and that could well limit the growth of aggregate demand. It is possible that the uptrend in commodity prices would be moderate in the face of lowered economic growth rates throughout the world.
If higher trending commodity prices do fuel general inflation, the hyper inflation that some fear would simply be accelerated. It is not a given that will happen. It is also a possibility that can not be dismissed.
If there is anything certain about the new normal, it can be expressed by quoting Fed Chairman Bernanke: The current situation is "unusually uncertain."
