The Commodity
Super Cycle - Less “super” and more “cycle”
The current so-called commodity
super-cycle started in 2002 and is a decade old.
2012 is starting to feel as though there is less “super” and more “cycle” in
this commodity move.
A drawdown
and more sensitivity to global macro growth makes the focus on microeconomic
effects and macroeconomic factors and less on long-term price themes more
relevant. There are some clear factors which affect whether there will be a
long cycle in commodities and they still have potential for causing a further
run-up in commodities, but their potential impact on current return generation
has to be tempered.
The DJUBS index declined in May
by 9.13 percent, the second worse month outside of the July through October
2008 market debacle in the last ten years for an YTD loss of 8.74 percent. The
commodity index is in a drawdown of 26.78 percent since the end of April 2011.
The DJUBS Agricultural index saw a decline of 9.90 percent and is down 7.37
percent for 2012. Its drawdown is
23.93 percent since the end of August.
The bearish bias for May was
extreme. All major energy markets were down double digits except for natural
gas which was affected by North American weather. Both base and precious metals
showed declines. Agriculture markets were down except for soybeans and meal,
feeder cattle, and hogs.
Continuation of any cycle across
all commodities is by definition a common macro-factor across markets and that
key macro-factor is still money. Alternatively, policies which inhibit trade
and growth can turn this super-cycle into a period of prolong decline. Behind
this backdrop are localized market factors which are still the most
important determinants driving markets.
The complexity of commodity
cycles
-
We have mixed views on the
concept of a commodity super cycle. There has been a strong cycle that has
reasonable economic foundation. It was interrupted with the 2008 financial
crisis. The general commodity market has improved, yet levels for many markets
are still below the highs of 2008 and is in another drawdown.
Large cycles in commodities exist.
However, the measurement of any so called super or long cycle is hard to
measure because there have been so few. There is no clear basis for saying what
should be the length of any commodity cycle whether super or not. While there
have been super cycles which have lasted for more than a dozen years, it is
clear that we are at the longer-end of any cycle.
The rationale for any strong
cycle is clearly associated with the overall global business cycle as well as
the production and investment cycles within commodity markets. There is a long
lead time between the production of commodities and the infrastructure development
to generate production. The
production development time for agriculture may be as short as one or two years.
For oil and metals, production development may take several years. Given these development times, there
will be a natural cycle that may not be as responsive as other production
processes.
Any super cycle has to be driven
not just by production and supply constraints but also by a shift in demand. We
have had a structural shift through the growing middle class in emerging
markets as well as overall GDP growth in developing countries. There has been an
extended period without an emerging market crisis as well as an extended period
of stable growth with controlled inflation. Government have embraced
market-based growth strategies that have raised income levels. Trade has
blossomed over last decade even with the financial crisis. The explosive growth
in the BRIC countries has been the most discussed theme on emerging market developments.
The longer-term demand side from
emerging markets as a driver in this super-cycle is real, but it is still subject
to changes in the global business cycle and changes in consumer tastes and
demand. For example, China is moving from a phase of infrastructure capital to
consumer development. The current decline in commodities matches the slowdown
in global growth over the last year. The commodity slowdown also correlates
with the reduction in emerging market stock prices. Given this correlation with
emerging market equities, the commodity markets are behaving like other asset
markets tied with growth cycles.
The length of this long cycle is
related to the structural changes in emerging markets. Commodity demand growth
will increase with longer-term world income levels and enhanced global trade. A
simple depiction of this relationship is looking at world trade year-over-year
changes against the year-over-year changes in the DJUBS total return index.
While the correlation is not be perfect, world trade growth as a proxy for
structural change in global markets matches with commodity gains and
loses. The slowdown in global
trade has coincided with the decline in commodity prices.
The seeds of destruction for any
super-cycle are sewn through price increases. Commodities are inherently
mean-reverting. As prices rise, there will be a natural rationing of demand. As
prices fall, the demand for any commodity will rise. Similarly, there will be a
greater response in supply as prices rise. Given the natural response of supply
and demand, there will be long-term price reversals at cycle extremes.
What is the cause of any super
cycle?
There may be four general reasons
for a strong super cycle:
- There is a structural constraint on demand or
more importantly, there are structural reasons why income cannot grow to create
demand. If there is a lifting of government constraints on demand, there will
be a long-term increase in prices as markets move to equilibrium.
- On the supply side, change in government
policies or structural changes will lead to price gains. If there was a period
of underinvestment, the ability to produce is curtailed and prices will rise.
Similarly, if there is a period of high real rates of interest, there will be
less investment in commodity production.
- Extended periods of low (high) price levels will
create more long-term demand (supply) which will see a general rise (fall) to
fair value. Consumer and producer behavior adapts to prolong price levels.
- There is an increase in
demand associated with inflation. A long-term cycle will occur if there is a
long-term excessive money growth.
Most super cycles have been
associated with war and economic upheaval. These periods are also associated with inflation. Price
cycles have been closely associated with wars. World War I, World War II, and
Cold War have all been periods of cycle extremes. The breakdown during the
Great Depression, the Industrial Revolution, the evolution of emerging markets
and the WTO have all served as catalysts for commodity cycles. The current
cycle is actually missing the more traditional global dislocation stories for
price highs. Not that we need a war or higher inflation, or structural change that will lead to higher price, but this is the requirement for a much longer up cycle.
