iM’s Business Cycle Index

We have temporarily suspended the update as no further meaningful information is conveyed by the BCI. We are working to adapt the graphics so that the end of a recession can be identified.

 

Recession Indicated — BCI Update 4/23/2020

Is your investment strategy protecting your assets from the next recession? Our Business Cycle Index is a tool to help you gauge recession risk.

Back testing the BCI (short for Business Cycle Index) shows that it would have provided, on average, a 20-week leading signal for the past seven recessions.

Update 4/23/2020

The US economy is in uncharted territory. The BCI signaled a recession warning on 4/2/2020. Regardless of the signal, we need to know how the COVID-19 pandemic has, or has not, influenced the calculations. Table 1 list the economic data that the BCI uses and combines the components for the index in “real time” i.e. the data is only incorporated into the index at its publication date.

Table 1. The components of the BCI
Validity Date Publication Date Economic Series
4/22/2020 4/22/2020 10-year Treasury yield (daily)
4/22/2020 4/22/2020 Three-month Treasury bill yield (daily)
4/22/2020 4/22/2010 S&P 500 (daily)
4/11/2020 4/23/2020 Continued Claims Seasonally Adjusted (weekly)
3/15/2020 4/3/2020 All Employees: Total Private Industries (monthly)
3/31/2020 4/22/2020 New houses for sale (monthly)
3/31/2020 4/22/2020 New houses sold (monthly)

From above table it is evident that the full effect of the COVID-19 pandemic on the BCI will only manifest itself after the April housing data is published.  Today’s Unemployment Insurance Weekly Claims Report shows that 20.7 million people (up from last week’s 17.4M) are claiming unemployment benefit. Furthermore, the March sales of new single‐family houses are 15.4% below February’s sales and is 9.5% below the March 2019 figures.

The BCI at 179.2 is down from last week’s 201.3.  Also, the 6-month smoothed annualized growth BCIg at -22.0 is down from last week’s -10.1.

The Business Cycle Index

Nobody can predict the arrival date of the next recession. However, using freely available economic data we derive a reliable signal that warns of an oncoming recession. We designed the Business Cycle Index to signal well in advance the beginning of a NBER-recession. The BCI uses the below listed economic data, downloaded from FRED.

  1. 10-year treasury yield (daily)
  2. 3-month treasury bill yield (daily)
  3. S&P500 (daily)
  4. Continues Claims Seasonally Adjusted (weekly)
  5. All Employees: Total Private Industries (monthly)
  6. New houses for sale (monthly)
  7. New houses sold (monthly)

The 6-month smoothed annualized growth rate of a series is a well-established method to extract an indicator from it. We use this method to obtain BCIg, i.e. the calculated growth rate with 6.0 added to it. The BCIg generates on past performance an average 11-week leading recession signal when it falls below zero.

Also, the index BCI retreats from its cyclic peak before a recession in a well-defined manner. This is the basis for the alternative indicator BCIp (and its variant BCIw) which gives an average 20-week leading signal to the next recession when BCIp falls below 25.

A more detailed  description of the BCI can be found here.

Investment Strategy

As a guide on how to use the BCI refer to Exit Signals for the Stock Market from iM’s Business Cycle Index and to Table 1 in this post.

Figure 2 graphs the history of BCI, BCIg, and the LOG(S&P500) since July 1967, and Figure 3 plots the history of BCIp. Overall 46 years of history that includes the seven last recessions each of which the BCIg, and BCIp, managed to signal. These graphics also include the weeks lead signaled to the then next recession.

The March 2020 Unemployment Rate Is Signaling A Recession

  • For what is considered to be a lagging indicator of the economy, the unemployment rate provides surprisingly good signals for the beginning and end of recessions.
  • This model, backtested to 1948, reliably provided recession signals.
  • The model, updated with the March 2020  rate of 4.4%, does now signal a recession.

A reliable source for recession forecasting is the unemployment rate, which can provide signals for the beginning and end of recessions (Appendix B charts the UER recession indicator for the period 1948 to 2015).

As anticipated (article link), the unemployment rate model (article link) updated with the March 2020 rate of 4.4% does now signal a recession.

The model relies on four indicators to signal recessions:

  • The short 12-period and a long 60-period exponential moving average (EMA) of the unemployment rate (UER).
  • The eight-month smoothed annualized growth rate of the UER (UERg).
  • The 19-week rate of change of the UER.

The criteria for the model to signal the start of recessions are given in the original article and repeated in the Appendix.

Referring to the chart below and looking at the end portion of it, one can see that all three of the conditions for the start of a recession have been met.

  • The UER at 4.4% is up from last month. The short EMA is above its long EMA, the blue and red graphs, respectively, and the spread, now at plus 0.26%, last month’s minus 0.11%.
  • UERg rose from minus 7.01% to plus 4.49%, far above zero – the green graph.
  • Also, the 19-week rate of change of the UER increased to plus 24.5%, also far above the 8% critical level – the black graph.

Based on the historic patterns of the unemployment rate indicators prior to recessions, one can reasonably conclude that the U.S. economy has enetered a recession.

Recession Probability

The probability of an imminent recession is 99%, as shown in the Figure below. The probability plot spans the period 1948 to 2020, encompassing eleven recessions.

Leads to recession starts

Leads to recession start from the UER model for the last eleven recessions:

  • Maximum lead time = 21 weeks (out of seven early signals)
  • Minimum lead time = -14 weeks (out of four late signals)
  • Average lead time = 2 weeks

Appendix

The model signals the start of a recession when any one of the following three conditions occurs:

  1. The short exponential moving average (EMA) of the unemployment rate (UER) rises and crosses the long EMA to the upside, and the difference between the two EMAs is at least 0.07.
  2. The unemployment rate growth rate (UERg) rises above zero, while the long EMA of the unemployment rate has a positive slope, and the difference between the long EMA at that time and the long EMA 10 weeks before is greater than 0.025.
  3. The 19-week rate of change of the UER is greater than 8.0%, while simultaneously the long EMA of the UER has a positive slope and the difference between the long EMA at the time and the long EMA 10 weeks earlier is greater than 0.015.
