Predicting the Next Recession

The recession callers were back in the first half of 2022, and some like ARK's Cathie Wood and Home Depot's Ken Langone claimed the US was already in a recession.   I disagreed and noted I wasn't even on recession watch!

We did see negative real GDP growth in Q1 and in Q2 - but that didn't mean the US economy was in a recession (and this has never been the definition of a US recession).  For a discussion of recessions, see NBER's What is a recession?  

Also, there are two measures of economic growth - Gross Domestic Product (GDP), and Gross Domestic Income (GDI).  See: Better Measure of Output: GDP or GDI?

The Bureau of Economic Analysis (BEA) produces two measures of national output which, in theory, should be equivalent. In practice, however, there are often substantive differences.

And when there are differences, GDP is usually revised towards GDI.  And guess what? GDI was positive in both Q1 and Q2.  And other measures of the economy were also positive, especially employment.  So, it is extremely unlikely there was a recession.

Way back in 2013, I wrote a post "Predicting the Next Recession. This post was in response to several recession forecasts (that were also incorrect).

In that 2013 post, I wrote:

The next recession will probably be caused by one of the following (from least likely to most likely):

3) An exogenous event such as a pandemic, significant military conflict, disruption of energy supplies for any reason, a major natural disaster (meteor strike, super volcano, etc), and a number of other low probability reasons. All of these events are possible, but they are unpredictable, and the probabilities are low that they will happen in the next few years or even decades.
emphasis added

Unfortunately, in 2020, one of those low probability events happened (pandemic), and that led to a recession in 2020.

2) Significant policy error. Two examples: not reaching a fiscal agreement and going off the "fiscal cliff" probably would have led to a recession, and Congress refusing to "pay the bills" would have been a policy error that would have taken the economy into recession. 

We've seen several policy errors, mostly related to immigration and trade during the previous administration, but none that would lead the economy into a recession.

1) Most of the post-WWII recessions were caused by the Fed tightening monetary policy to slow inflation. I think this is the most likely cause of the next recession. Usually, when inflation starts to become a concern, the Fed tries to engineer a "soft landing", and frequently the result is a recession.

And this most common cause of a recession is the current concern.  Since inflation picked up, mostly due to the pandemic (stimulus spending, supply constraints) and due to the invasion of Ukraine, the Fed has embarked on a tightening cycle to slow inflation.   

The Fed cannot ease pandemic related supply constraints (except by curbing demand), and the Fed cannot stop the war.  So, there is a possibility that the Fed will tighten too much and that will lead to a "hard landing" (aka recession).

The key will be to watch housing.  Housing is the main transmission mechanism for Fed policy.   One of my favorite models for business cycle forecasting uses new home sales (also housing starts and residential investment).   I also look at the yield curve, but I've found new home sales is generally more useful.  (See my post in 2019: Don't Freak Out about the Yield Curve)

For the economy, what I focus on is single family starts and new home sales.   For the bottoms and tops of key housing activity, here is a graph of Single-family housing starts, New Home Sales, and Residential Investment (RI) as a percent of GDP.

Note: The pandemic has distorted the economic data, and as I've noted many times, we can't be a slave to any model.

The arrows point to some of the earlier peaks and troughs for these three measures - and the most recent peak.

The purpose of this graph is to show that these three indicators generally reach peaks and troughs together. Note that Residential Investment is quarterly and single-family starts and new home sales are monthly.

New home sales and single-family starts turned down last year, but that was partly due to the huge surge in sales during the pandemic - and then rebounded somewhat.   Now both new home sales and single-family starts have turned down in response to higher mortgage rates.   Residential investment has also peaked.

The second graph shows the YoY change in New Home Sales from the Census Bureau.  Currently new home sales (based on 3-month average) are down 10% year-over-year.

Note: the New Home Sales data is smoothed using a three month centered average before calculating the YoY change. The Census Bureau data starts in 1963.

Some observations:

1) When the YoY change in New Home Sales falls about 20%, usually a recession will follow. An exception for this data series was the mid '60s when the Vietnam buildup kept the economy out of recession.   Another exception was in late 2021 - we saw a significant YoY decline in new home sales related to the pandemic and the surge in new home sales in the second half of 2020.  I ignored that pandemic distortion.

Also note that the sharp decline in 2010 was related to the housing tax credit policy in 2009 - and was just a continuation of the housing bust.

2) It is also interesting to look at the '86/'87 and the mid '90s periods. New Home sales fell in both of these periods, although not quite 20%. As I noted in earlier posts, the mid '80s saw a surge in defense spending and MEW that more than offset the decline in New Home sales. In the mid '90s, nonresidential investment remained strong.

If the Fed tightening cycle will lead to a recession, we should see housing turn down first (new home sales, single family starts, residential investment).  This is now happening, but this usually leads the economy by a year or more.  So, we might be looking at a recession in 2023.

There are other indicators too - such as the yield curve and heavy truck sales - but mostly I'll be watching housing.

Note: I will look at comparing to 2019 to remove the pandemic distortions.
