May 19 The London Metal Exchange (LME)
started publishing its Commitments of Traders Report (COTR) in
July 2014.

It came after calls, primarily from the exchange’s
industrial users, for more transparency, first and foremost
about the exchange’s financial users.

The “money manager” category, it was hoped, would light up
the path of the money men as they moved through the markets.

And to an extent it has.

The COTR figures have inserted themselves into the base
metals narrative, just as in other parts of the commodities

But are they enlightening or misleading us?

How do we explain, for example, why the funds just about
always seem to have been long LME copper, even when the market
was in the final throes of a five-year price slump?

And since the LME’s COTR is but a carbon copy of that used
in U.S. markets, how comfortable are we with the fact that funds
earlier this year built a long position on the CME copper
contract that eclipsed anything ever seen before?

Are these reports painting a true picture of fund activity
in copper?

Or are we being blinded by transparency?

There is an interesting comparison to be made between the
COTR version of fund positioning in LME copper and that
published by LME broker Marex Spectron.

The two might be said to travel in the same direction most
of the time but often with very different readings.

Marex’s latest assessment is that funds are marginally net
long of LME copper to the tune of 1,700 lots, or around 0.9
percent of open interest.

The LME COTR, however, shows a net money manager long of
40,338 lots, or almost 9 percent of open interest.

It’s a big difference, isn’t it?

And one that Marex Spectron’s global head of analytics, Guy
Wolf, has recently tackled in a research note with the
self-explanatory title “Base Metals Bull Market”.

Marex uses what it calls its “Nanolytics” methodology to
track speculative positioning.

It’s a fancy word for reassembling all the data that exists
around any trade, the number and type of bids and asks, the
speed of response, all the stuff that was once intuitive to a
human floor trader but is now lost in the electronic ether.

Given the speed of trading, often at milliseconds and
faster, it takes a lot of computing power but Wolf’s view is
that what computers rent apart, computers can reunite.


The first big problem with the COTR methodology, according
to Wolf, is one of classification.

Any user can only be placed in one category determined by
their “predominant activity”.

Imagine you’re the broker having to work out the appropriate
box to tick for a client. The client is a big fund manager with
large amounts of money invested in a broad passive commodity
index. But the client also runs an active metals fund, which
generates more trading volume with greater frequency.

You’ll probably choose “money manager”, but if you do,
you’ve just also moved the client’s index-linked holdings out of
the “broker dealer index trader” category.

Such seepage of passive money into what should denote active
money is a recurring and volatile theme across many commodity
markets, according to Wolf, but one that is compounded further
by the nature of the LME.

The LME’s own figures show that its members account for a
substantial 49 percent of total open interest.

“There is no visibility on the originator” of positions
sitting in a member’s account, meaning a significant proportion
of activity remains untrackable, Wolf argues.

The double takeaway here is that not everything that counts
can be counted and not everything that can be counted counts.

The official “money manager” category is both likely missing
some fund activity and capturing an element which is passive
rather than active, causing that built-in bias to the long side.


Wolf doesn’t dispute the spike in fund longs in the copper
market earlier this year. Marex’s own methodology caught the
same trend-driven buying momentum.

But he does caution that there may be more going on in that
all-time long fund position apparently accumulated on the CME
copper contract than might at first meet the eye.

Drawing on an extensive analysis of the WTI oil market, Wolf
makes a case that a cross-commodity increase in speculative
length may be investment structures moving from the
over-the-counter shadows to the exchange space.

“Structuring producer hedges set off against pension fund
investor length was a good business to be in” a couple of years
ago before it was undermined by the way new regulations treat
commodities on bank balance sheets, Wolf notes.

As such instruments come to the end of their fixed terms,
they are being rolled onto exchanges, inflating the apparent
fund presence, he argues.

Copper is a core component of all the big commodity indices
and would be included in any such shadow-land investment basket.

Another shifting dynamic is what appears to be a flow of
speculative activity out of China towards both the CME and the
LME, according to Wolf.

Copper open interest on the Shanghai Futures Exchange (ShFE)
fell by just over 1.5 million tonnes over the second half of

Some of this may have found a new home in the CME copper
contract, although Wolf argues that more actually appeared to
migrate to the LME over the same timeframe.

That may seem strange given all the hullabaloo about falling
LME volumes, but much of that decline has taken place on the
short-dated carries that don’t exist in the CME’s futures

Strip those out of the equation and compare CME open
interest and open interest on the LME third Wednesday prime
prompts and “the view that (CME) is taking share consistently
from the LME is not supported by the data.”


Leakage of passive money across categories, leakage of OTC
investment assets onto exchanges and leakage of speculative
money out of China may all be inflating funds’ apparent
participation in copper.

Wolf’s bold call is that “we don’t see the speculative
community as positioned for a bull market in base metals at

You may not agree, but if he’s right it’s only a matter of
time before we see new “record” fund longs in copper on both
sides of the Atlantic.

Except they won’t be true “records” if the components of the
count have been subtly changing all the time.
