Special Topic: Can you trust recession forecasts?

The 12-month probability of a U.S. recession based on a simple three-factor model is 92%. Unemployment is rising, the Manufacturing Purchasing Managers’ Index (PMI) is at 47, and the yield curve is flashing red. This data configuration is reminiscent of early 2007. 

Scary.  

But it’s hard to trust these probabilities. The data are messy, and some signals are flashing green.  

It’s not surprising, then, that there’s no consensus among economists on the likelihood of a recession among economists. In early August, many were arguing that the economy was at the “highest risk” of recession.¹ Two weeks later, on August 19, Goldman Sachs lowered its recession risk forecast from 25% to 20% because the recent data “shows no sign of recession.”² What gives?  

Adding variables to the model built by our Multi-Asset research team puts us closer to the Goldman view—indeed, it paints an even more favorable picture. If we add stock index returns from the last year and the level of unemployment to our model, the statistical recession probability drops from 92% to 11%. (See important caveat on these probabilities below.)

My view: I’m relatively optimistic about the U.S. economy and trust this broader model. Equity valuations and spread levels agree. Hence, opportunities to significantly overweight risk assets are limited. The Asset Allocation Committee’s analysis supports a fully invested (neutral) or slightly risk-on position. Investors could also consider averaging-in equities throughout this historically weak season and potential election-related volatility. 

The model 

How do we arrive at the 92% and 11% probabilities?  

We start with three indicators:  

• The Institute for Supply Management’s Manufacturing PMI 

• The difference between the 10- and 2-year U.S. Treasury yields (the 10-2 yield curve) 

• The change in U.S. unemployment over the last year 

Our model accounts for volatilities and correlations across the indicators. This is important. It’s not just about the level of each variable; it’s also about the “configuration” or interaction among them.³ 

The table below shows current values for each variable compared with historical averages one month before and during recessions.  

According to our model, using these three indicators generates a statistical probability of recession of 92%. Historically, when moving into recessions, Manufacturing PMIs have fallen, the yield curve has de-inverted, and unemployment has risen—all similar to the current environment. It’s a toxic brew of indicators in precisely the right proportions for a recession.   

Next, we add the following two variables: 

• S&P 500 returns (last 12 months) 

• U.S. Unemployment level 

Repeating the same statistical calculations, the probability falls to 11%. Based on historical evidence, strong stock market returns and low unemployment rates are unlikely to signal a recession. Of course, using stock returns can lead to a circular reference when making investment decisions, but stocks are considered a leading indicator of recessions. 

A caveat: We tested several variations of these models, and the 92% to 11% disparity between any two was the highest—and best amplifies my point that the data that you choose to use has a major impact on recession probabilities. Across iterations, however, we observed the same general tendency of model probabilities to drop when adding a broader range of indicators that account for market variables (stock returns, credit spreads) and employment data levels (unemployment, claims, job openings, etc.). Adding Services PMI also lowered the probability.

Conclusions 

My takeaway is not that “this time is different”—saying that is worse than swearing in some investment circles. But I think the recession narrative for the U.S. has conveniently ignored the bright green “cushions” created by the pandemic normalization, aggressive fiscal spending, and the positive liquidity impact of preemptive Fed cuts. 

As for our positioning, with bright red signals to the left and bright green signals to the right, should we stay in the middle lane when it comes to stocks versus bonds?  

Perhaps we should since equities seem to be pricing in the optimistic scenario. However, our Asset Allocation Committee has started discussing at what S&P 500 level we would be prepared to add to risk assets should we encounter volatility over the next few months— which is highly likely given the upcoming election.

Winsorized refers to a method of averaging that minimizes the impact of outlying numbers. It is a statistical technique that limits the impact of outliers in a data set by replacing extreme values with less extreme values.
