Below is an extract from a commentary originally posted at www.speculative-investor.com on
9th August 2007.
Overview
As explained in the past, when it comes to the "commodity supercycle" we are
definitely sceptics. We concur with the view that commodity prices in general
and metal prices in particular are in long-term upward trends, but we do not
think these trends are being driven by the strong growth of "Chindia" or the
global spread of capitalism or the industrialisation of Asia or the movement
of billions of people to the ranks of the "middle class" or any of the other
catchphrases routinely used to neatly explain the price action. In our opinion,
these explanations rank alongside slogans such as "new economy" and "technology-driven
productivity miracle" that were used to legitimise the price action of tech
stocks during the boom of the late-1990s.
As we see it, inflation (money supply growth) is causing a rolling boom/bust
cycle whereby the combination of relative valuation and scarcity determines
which sectors will be the major beneficiaries of inflation during the current
cycle and which sectors will be relegated to the investment 'scrap heap'.
The analysts who concoct simple explanations based on real (non-monetary)
changes in the world and repeat these explanations in mantra-like fashion will
look incredibly prescient for a long time, even though they largely ignore
the monetary factors that are actually at the root of the price changes. Some
of these analysts will even take-on the status of prophets due to their apparent
abilities to see the future. But the inflation-fueled boom will eventually
turn into a bust, even if the touted fundamental bases for the boom persist.
For example, the growth of the internet and technological progress in general
did not 'miss a beat' when the NASDAQ crashed. All that happened was that the
primary focus of inflation shifted, causing the "new economy" prophets to fade
away and bringing to the fore a new bunch of prophets who chant "commodity
supercycle".
In any case, regardless of what's fueling it the base metals bull market will
probably continue for at least a few more years. The main concern we have at
this time isn't with the next few years, because there will almost certainly
be a lot more inflation in the future and as far as we can tell the base metals
are not yet over-valued relative to anything except gold. Our main concern
at this time is with the next few months, because although the prices of most
base metals held up fairly well during the stock market's initial decline the
backdrop has recently become markedly less favourable for growth-oriented investments.
To put it another way, the things that have recently made us more bullish on
gold with respect to the short- and intermediate-terms have increased the downside
risk in the base metals.
Current Market Situation
As evidenced by the following chart, copper is not far below its May-2006
peak. This doesn't tell us much about the future, though, because the price
action since the May-2006 peak could just as reasonably be interpreted as a
consolidation that is about to end via an upside breakout or as a consolidation
that will require, as a minimum, a test of the early-2007 low ($2.50) before
it comes to an end.

We favour the latter interpretation, mainly because the liquidity contraction
catalysed by the problems in the US mortgage market will most likely have an
adverse effect on global growth. Even if there isn't actually a significant
change in copper consumption over the next few months, the financial markets
always attempt to discount the future and the risk is that the copper market
will discount a future growth slowdown.
We also note that the aluminium price chart included below looks considerably
more bearish than the copper price chart shown above. This is potentially significant
because aluminium can be substituted for copper in some applications.

The base metals that appear to have the least amount of downside risk in the
short-term are nickel and zinc -- nickel because it has already tanked and
zinc because LME warehouse stocks of the metal are very low and continuing
to fall.
