Boom-Bust Cycle Update

 | Nov 23, 2021 03:14AM ET

In a 9 November post I wrote that the US TMS (True Money Supply) growth rate had fallen far enough to suggest that the next trend reversal in credit spreads from narrowing to widening would mark the start of a boom-to-bust transition rather than just an interruption to the boom. What’s the current situation?

Before answering the above question it’s worth reiterating that a trend reversal in credit spreads (from narrowing to widening) isn’t the only early warning that a boom-to-bust transition has begun for the US economy.

As mentioned in previous posts (for example, here), another necessary signal is pronounced weakness in the Industrial Metals Index (GYX) relative to the gold price. In other words, prior to the end of a boom* there will be upward trend reversals in credit spread indicators such as the US High Yield Index Option-Adjusted Spread (HYIOAS) and a downward trend reversal in the GYX/gold ratio. As an aside, the most recent bust began in early-October of 2018 and ended in early-June of 2020.

The following daily chart shows the HYIOAS.

In early-July of this year the HYIOAS was at its lowest level in more than 10 years and not far from an all-time low. It spiked upward around the middle of July and then returned to near its low, where it remains (it ended last week at around 3.2%).

Note that a credit-spread reversal would be signaled by the HYIOAS making a higher short-term high AND moving back above 4%. The first of these criteria (the initial warning) would be triggered by a move above 3.5%.
