I was recently asked the following question: There was always enough coin
production capacity under the gold standard when a gold coins were struck on
private account free of seigniorage charges and in
unlimited quantity. With all the technological improvements of the past 100
years, why is there any question about "enough capacity"?
While I work at a mint, I am not a manufacturing person so have only picked
up a cursory knowledge of coin production. I sought out additional
information from the Perth Mint’s CEO, Ed Harbuz,
who ran the South African Mint before coming to Perth and is an engineer by
trade and a manufacturing guy, so he knows not only the general issues but
also the state of the operations of most of the other mints. This has helped
inform my comments below.
Firstly, under the gold standard mints were geared up to do nothing but gold
and silver coins. Now they are geared up to do base metal coins with gold and
silver a niche or side part of the operations, from a volume point of view.
The Perth Mint is different in this respect because it is focused on precious
metals, whereas other mints are primarily circulating coin operations.
Secondly, lets distinguish between blank manufacturing and minting, they two
key steps in making a coin. Blank manufacturing is process manufacturing
where inventory is measured in weights and losses and scrap are involved.
Minting is unit manufacturing where inventory is measured in units (i.e.
number of coins) and is much simpler.
Most mints have many presses, and probably too many for their circulating
coin needs. However, the technological improvements made for these have been
focused on circulating coin production. They are high speed presses (12 coins
a second) for small sizes with low relief designs – all optimised for high volume/low quality production.
Certainly most of these presses can be converted to strike precious metal
coins, but it is not just a case of putting a new die in and feeding in gold
blanks – physical changes and reprogramming is required. In addition,
some of the presses are specialised for small coins
and would not be able to take the usual 1oz gold coin size. So while it is
possible to utilise circulating coin presses to do
gold coins, there would still be some work and capital investment required.
However, minting is not really where the problem is. It is blank
manufacturing where the bottleneck is. Blank manufacturing, in the trade
parlance, involves melting, casting, rolling, cutting out of the blanks
(blanking), annealing and various surface treatment processes. It is a far
more involved and “messy” process than minting. It is Ed’s
view that while there may be enough presses (once converted) in the world to
stamp out gold coins there is simply not enough gold blank manufacturing
capacity in the world to meet the current demand levels. So can we not
convert existing base metal blank manufacturing to gold?
Here is where the technological improvements made are of no use. Mass base
metal blank manufacturing deals in metals that are significantly less value
that the face value of the coin. As a result, the process is optimised for speed, not quality or security: if a blank
is no good, throw it away; weight control tolerances are lax (do you care if
your copper coin has slightly more or less copper in it?); metal evaporating
when it is melted is not recovered and so on. You cannot allow any of these
things with gold, due to its high cost. To convert base metal blank
manufacturing you would have to install weight control machines, scrubbers to
collect evaporated gold, lock down the building and install physical
security, etc. These are major changes and without them the cost of
production of a gold coin would be very high.
The result is that circulating coin mints are not optimised/designed
for precious metal coining and can only be done so with difficultly.
Certainly, if we moved to a gold standard then conversion of base metal
circulating coin equipment or addition of dedicated precious metal coin
production lines would be made and we would have enough coins.
In the interim, mints will only invest capital in precious metal production
facilities if they believe that the current demand for gold coins will
continue for a number of years, otherwise they will not recover their
investment. The hesitancy of mints to gear up is because the cost of a modern
full precious metal coin production line is high.
What sort of investment is required? One Grabener
coin press (the most commonly used one) is circa $1 million. That is just for
the press, for blank manufacture you need melting furnaces, breakdown mills,
pickling plants, weighing machines, scrubbers, vacuum furnances
etc etc. If you look at the last Perth Mint annual
report (which is almost exclusively a precious metals mint), you will see
that on page 24 the cost of plant and equipment (pre depreciation) is AUD 22
million. That equipment supported only 8.1 million blanks and an 8% share of
the world gold bullion coin market. And we haven’t even begun to
consider working capital requirements cover cash costs and work-in-progress
inventory.
One can see that to meet mass market demand for real (gold) money many times
the Perth Mint’s capacity would be required across the minting industry (public and/or private). Thus a
substantial amount of dollar investment is required.
This discussion of investment then leads us to ponder Professor Fekete’s comments in The Mechanism of Capital Destruction: “A
falling interest-rate structure is lethal. It is an insidious destroyer of
capital.”
Now most government mints are not affected by interest rates or commercial
factors. But even so I think, as a general statement, that we cannot expect
Government mints to make the sort of decisive and entrepreneurial decision
required to invest to meet future demand; to take the gamble that retail coin
demand will continue. This sort of high risk/high return is not in their
bureaucratic nature. For those of a conspiracy bent, this is an academic
question anyway as the mints have been told by their masters, those that set
the interest rates, to make as few gold coins as (plausibly) possible.
This then leaves us relying on private mints to meet the demand. But then is
the capital destruction nature of a falling/rising/oscillating interest rate
causing private mints to be unwilling to invest in the equipment to meet the
demand for coins? And in these markets where will they get the funding from
anyway?
The conclusion is that we will continue to have coin shortages (and high
premiums) while retail demand for gold continues. In some sense this is
necessary, as it is an economic signal to minters to encourage them to invest
to make these extraordinary profits. But will this signal work in the current
environment? We have a catch-22 type situation (or insidious conspiracy, if
you prefer): the interest rate policy of Government destroys the capital of
private mints, making them unable/unwilling to spend on equipment to make
enough coins to meet demand, but neither are Government mints commercial
enough to invest (or told not to). Either way, shall we ever have enough coin
production capacity?
There is an alternative view. For all other manufacturers, a zero or near
zero interest rate does not cause them to say “money is free, lets
borrow heaps and build additional car manufacturing lines”. This is
because the sort of dire economic environment that drives the interest rate
to zero is the same one that drives consumer demand down. People are not
concerned about making money, they are concerned about conserving money (or
more accurately, wealth).
However, is it not this demand to conserve wealth that also results in
driving demand for gold up? If so, unlike other manufacturers who see falling
prices and sales, minters would see that they have increasing demand and
increasing prices (premiums). Would this not make taking on zero cost debt a
low risk decision? As mentioned earlier, the key is belief by minters in
sustainable demand (see this blog for a discussion on the types of issues
involved).
While you may consider the unprecedented demand that has occurred as a clear
signal, the minters obviously do not as they are rationing supply instead of
increasing it. How long before they act? Hard even for me to say, and I work
inside one.
