The University of Michigan Consumer Sentiment Index final report for December came in at 69.9, up from the 67.7 December preliminary reading and an encouraging increase from the final report of 64.1 for November. The Briefing.com consensus expectation was for 68.0.
See the chart below for a long-term perspective on this widely watched index. Because the sentiment index has trended upward since its inception in 1978, I’ve added a linear regression to help understand the pattern of reversion to the trend. I’ve also highlighted recessions and included real GDP to help evaluate the correlation between the Michigan Consumer Sentiment Index and the broader economy.
To put today’s report into the larger historical context since its beginning in 1978, consumer sentiment is about 18% below the average reading (arithmetic mean), 17% below the geometric mean, and 18% below the regression line on the chart above. The current index level is at the 16.7 percentile of the 408 monthly data points in this series.
The Michigan average over since its inception is 85.6. During non-recessionary years the average is 88.2. The average during the five recessions is 69.3. So the current sentiment level of 69.9 is about at the recession average.
The indicator can be somewhat volatile. For a visual sense of the volatility here is a chart with the monthly data and a three-month moving average.
For the sake of comparison here is a chart of the Conference Board’s Consumer Confidence Index (monthly update here). The Conference Board Index is the more volatile of the two, but the broad pattern and general trends are remarkably similar to the Michigan Index.
And finally, the prevailing mood of the Michigan survey is also similar to the mood of small business owners, as captured by the NFIB Business Optimism Index (monthly update here).
The trend in sentiment since the Financial Crisis lows had been one of slow improvement, but it topped out in February of this year at 77.5 and plunged to an interim low of 55.7 in August. The steady rise since the August trough is encouraging, especially as we move through the holiday shopping season. But in the larger historical context, the December final number from the Michigan survey remains at a level most commonly associated with recessions.
Caveats on the Use of University of Michigan Consumer Sentiment
This release is frequently released early. It can come out as early as 9:55am EST. The official release time is 10:00. Base year 1966=100. A survey of consumer attitudes concerning both the present situation as well as expectations regarding economic conditions conducted by the University of Michigan. For the preliminary release approximately three hundred consumers are surveyed while five hundred are interviewed for the final figure. The level of consumer sentiment is related to the strength of consumer spending. Please note that this report is released twice per month. The first is a preliminary figure while the second is the final (revised) figure.
This is a survey, a quantification of opinion rather than facts and data. The question remains – does sentiment lead or truly correlate to any economic activity? Since 1990, there seems to be a loose general correlation to real household income growth.
