Retail sales was significantly slower according to US Census headline data. There is almost no year-over-year growth when one inflation adjusts the data.

Analyst Opinion of Retail Sales

There was a slight downward adjustment of last month's data. The real test of strength is the rolling averages which declined.

Things to consider when viewing this data:

• it is not inflation adjusted - and when you do there is almost no growth year-over-year.
• the three-month rolling averages of the unadjusted data declined.

The year-over-year growth rate in inflation-adjusted retail sales and retail employment have diverged.

Backward data revisions were upward.

Econintersect Analysis:

• unadjusted sales rate of growth decelerated 3.5 % month-over-month, and up1.4 % year-over-year.
• unadjusted sales 3-month rolling year-over-year average growth decelerated 3.1 % month-over-month, up 4.2 % year-over-year.

• unadjusted sales (but inflation adjusted) up 0.2 % year-over-year
• this is an advance report. Please see caveats below-showing variations between the advance report and the "final".
• in the seasonally adjusted data - the weakness was widespread.

U.S. Census Headlines:

• seasonally adjusted sales down 1.2 % month-over-month, up 2.3 % year-over-year (published up 4.6 % YoY last month).
• the market was expecting (from Econoday):

From the U.S. Census Bureau press release:

Advance estimates of U.S. retail and food services sales for December 2018, adjusted for seasonal variation and holiday and trading-day differences, but not for price changes, were $505.8 billion, a decrease of 1.2 percent (±0.5 percent) from the previous month, but 2.3 percent (±0.5 percent) above December 2017. Total sales for the 12 months of 2018 were up 5.0 percent (±1.4 percent) from 2017. Total sales for the October 2018 through December 2018 period were up 3.7 percent (±0.5 percent) from the same period a year ago. The October 2018 to November 2018 percent change was revised from up 0.2 percent (±0.5 percent)* to up 0.1 percent (±0.4 percent)*. Retail trade sales were down 1.3 percent (±0.5 percent) from November 2018, but 2.1 percent (±0.5 percent) above last year. Clothing and clothing accessories stores were up 4.7 percent (±1.4 percent) from December 2017, while food services and drinking places were up 4.0 percent (±2.5 percent) from last year.

General Information

Data collection and processing were delayed for this indicator release due to the lapse in federal funding from December 22, 2018 through January 25, 2019. Processing and data quality were monitored throughout and response rates were at or above normal levels for this release.

The differences between the headlines and Econintersect are due to different approaches to seasonal adjustment (see caveats at the end of this post).

Declines of short duration often occur in the seasonally adjusted series without a recession resulting.

Using employment as a gauge to check growth, employment in retail has been declining.

And finally, as retail sales can be a component of determining a recession start date, the zero line of the graph below could be an indicator a recession was underway (or about to begin).

Caveats On Advance Retail Sales

This data release is based on estimates. However, the estimates have proven to be fairly accurate although tend to miss at economic turning points. Therefore up to three months are subject to backward revisions, although normally slight, can sometimes be modest.

The data in this series is not inflation adjusted - and Econintersect adjusts using CPI less shelter CUSR0000SA0L2. The St. Louis Fed also inflation adjusts the Census seasonally adjusted data. The last two recessions began as the inflation adjusted retail sales crossed the zero growth line.

As in most US Census reports, Econintersect does not agree with the seasonal adjustment methodology used and provides an alternate analysis. The issue is that the exceptionally large recession and subsequent economic roller coaster has caused data distortions that become exaggerated when the seasonal adjustment methodology uses more than one year's worth of data. Further, Econintersectbelieves there is a New Normal seasonality. Using data prior to the end of the recession for seasonal analysis could provide the wrong conclusion.

The impact of the monthly retail sales data on GDP is not straight forward. Real GDP (of which the consumer is over 60%) is adjusted for inflation. Further, GDP is an analysis of quarter-over-quarter or year-over-year growth, while retail sales is a monthly data series.

Econintersect determines the month-over-month change by subtracting the current month's year-over-year change from the previous month's year-over-year change.
