The Gold-Silver Ratio

For Valentine's Day, a little something for you who love silver.

Or gold

A couple of weeks ago, Wheaton Precious Metals released a very useful study on the gold-silver ratio. Today I would like to take a look at some of its implications.

The most important implication is one that everyone needs a little time to absorb. That is that there is no characteristic value for the gold-silver ratio.

That means that there is no "true north", or no mythic value (16, for instance) to which it is attracted, and to which it would return if only the world stopped manipulating its price.

The Wheaton conclusions are quite definite. The gold-silver rises during deflationary periods and disinflationary periods (we'll look at this distinction shortly). The gold-silver ratio falls during inflationary periods.


What is unclear is whether a rising GSR causes deflation, or deflation causes a rising GSR. I know which one I believe.

Let's test this against some measures I've used for deflation/inflation. I'll use the weekly chart of USDX vs gold price, weekly, going back to the beginning of 2008.


It is a busy visual, but what we want to do is look at longer-scale variations. Intervals when both the USDX index and the gold price rise are considered deflationary. If gold rises and the US dollar index falls, we have inflation (hence inflation and deflation are not opposites). Gold falling and the dollar rising will be disinflation, and I suppose that if both gold and the US dollar fall, we must have disdeflation, although I have never seen that word anywhere. It's a little hard to say, so it might be best to leave it nameless, and remember that if it ever happens, you should be shorting gold stocks.

Through most of 2008, the graph above suggests we were experiencing disinflation, and over that interval, GSR rises from 55.7 to 77.1

Much of 2009 was characterized by inflation, and the GSR fell from 77.1 to 63.3.

Until the middle of 2010, we had disinflation, and the GSR rose slightly.

The big inflationary pulse into late 2011 saw the GSR falling to 40.8. The final blow-off in the gold price did not see any movement in the US dollar index, so it technically lies between inflation and deflation, but I don't know what to call it. The GSR actually rose during that interval, which makes some sense as the gold price rose over $200 in that time.

The following disinflationary episode that lasted through 2013 saw the GSR rise to 65.9.

Since then, the dominant trend has been deflationary, although realistically there have only been two deflationary pulses--through early 2015 (GSR 74.5) and over the past 18 months (GSR at 88.6). Most of the time has been consumed by short inflation-disinflation cycles, with slight rises and falls of the GSR without significant trend.

Over the entire chart (twelve years) the big picture is deflation, but most of that has been accommodated through cycles of inflation and disinflation.

So long as deflationary conditions persist, the GSR may rise without limit. As long as debts are created beyond any ability to repay them, deflationary conditions will rule. Under such conditions, despite the GSR being pretty much the highest in history, gold remains a better investment than silver.

However, as much of the actual deflationary effect is brought about by cycles of inflation and disinflation, there are  brief intervals where silver makes a better investment than gold. But rather than using the level of the GSR as your selection criterion, you need to look closely at monetary policy instead.

Modification of probability density for stocks rising steeply in price

Today's study is based on an 18-month record of daily closing prices for Silver Wheaton Corp. (disclosure--long position)


The chart shows a pretty nice move up to the $45 range, and has since pulled back.

The double bumps near the end of the record provide enough information to define a time delay at the first minimum of the average mutual information of the time series against sequential lags. A reasonable approximation of this lag is sixteen trading days, and this lag is used in creating the phase space portrait below.


Share price phase space and turbulent flow

The turbulent eddies diffuse outward as share prices rise. The simplest reason is there is no inherent scale for price changes.


The graph above shows the daily change in closing price for Silver Wheaton, expressed as a percentage, over the past 18 months. There is no real trend, nor are the percentage moves larger or smaller when the price was higher. The effect of this is to produce a diffuse phase space portrait for the higher price area of the graph. Consequently, when the probability density is plotted, the areas in phase space representing higher prices will have lower probabilities than might otherwise be the case.

The simplest way to correct for this effect is to plot the reconstructed phase space on a logarithmic scale rather than a normal scale.


The bin size remains constant, which really means that the bins become larger as we move into the high-price
area of the reconstructed state space. The effect is to increase somewhat the probability density in the high-price area.


The only compelling attractors for price here are in the 17-$21 range. Like the Pelangio chart last time, this is a reflection of the amount of time spent at these price levels. The only cure is to stay at higher prices (SLW is near $35 at this writing).

Also recall that like most other technical approaches, resistance and support are due to psychological factors. For mining companies the drill can defeat technical analysis.
