I consider the gold/GYX ratio (the price of gold relative to the price of a basket of industrial metals) to be the ultimate boom-bust indicator. With monotonous regularity, the gold price trends downward relative to the prices of industrial metals during the boom periods and upward relative to the prices of industrial metals during the ensuing busts. Not surprisingly, given economic reality, in addition to being an excellent boom-bust indicator the relative performances of gold and the industrial metals is also an excellent indicator of general (societal) time preference.

Time preference is the value placed on consumption in the present relative to future consumption. In particular, rising time preference involves an increase in the desire to buy consumer goods in the present and, by extension, a decrease in the desire to save or make long-term investments, while falling time preference involves a growing desire to put-off current consumption in order to save or make long-term investments. As an aside, interest rates naturally stem from time preference in that all else being equal — which it often isn’t — people will prefer getting an item now to getting the same item at some future time. For example, even if there is no credit risk, a dollar in the hand today will always have a higher value than the promise of a dollar in the future. The greater perceived value of the present good relative to the future good can be expressed as an interest rate.

Major trends in time preference go hand-in-hand with the boom-bust cycle. During booms fueled by monetary inflation people temporarily feel richer and spend more freely, largely because debt is cheap and easy to come by. This means that booms are accompanied by rising time preference (a greater eagerness to consume). During the ensuing busts, the mistakes and recklessness of the preceding boom come to light. There is a general “pulling in of horns” as the focus turns to the repairing of balance sheets and the building-up of cash reserves. This means that busts are accompanied by falling time preference (a greater desire to save).
