Note: This commentary has been updated to incorporate the December data for Industrial Production.

Official recession calls are the responsibility of the NBER Business Cycle Dating Committee, which is understandably vague about the specific indicators on which they base their decisions. This committee statement is about as close as they get to identifying their method.

There is, however, a general belief that there are four big indicators that the committee weighs heavily in their cycle identification process. They are:

  • Nonfarm Employment
  • Industrial Production
  • Real Retail Sales
  • Real Personal Income (excluding Transfer Receipts)
  • The Latest Indicator Data

    According to the Federal Reserve:

    Industrial production declined 0.4 percent in December, primarily as a result of cutbacks for utilities and mining. The decrease for total industrial production in November was larger than previously reported, but upward revisions to earlier months left the level of the index in November only slightly below its initial estimate. For the fourth quarter as a whole, industrial production fell at an annual rate of 3.4 percent. Manufacturing output edged down in December. The index for utilities dropped 2.0 percent, as continued warmer-than-usual temperatures reduced demand for heating. Mining production decreased 0.8 percent in December for its fourth consecutive monthly decline. At 106.0 percent of its 2012 average, total industrial production in December was 1.8 percent below its year-earlier level. Capacity utilization for the industrial sector decreased 0.4 percentage point in December to 76.5 percent, a rate that is 3.6 percentage points below its long-run (1972–2014) average.

    The full report is available here.

    Today’s report on Industrial Production for December shows a month-over-month decline of 0.4 percent (0.36 percent to two decimal places), which was below the Investing.com consensus of a 0.2 percent decline. The previous three months were revised downward. this indicator has posted a monthly decline for ten of the last twelve months and is down 1.75% year-over-year, a year-over-year level that is lower than at the start of all ten recessions since 1950.

    In some respects, Industrial Production is the least useful of the Big Four economic indicators. It’s a hodge-podge of underlying index components and subject to major revisions, which undercuts its value as a near-term indicator of economic health. As a long-term indicator, it needs two key adjustments to correlate with economic reality. First, it should be adjusted for inflation using some sort of deflator relevant to production. Second, it should be population-adjusted.

    The chart below is another way to look at Industrial Production over the long haul. It uses the Producer Price Index for All Commodities as the deflator and Census Bureau’s mid-month population estimates to adjust for population growth. We’ve indexed the adjusted series so that 2012=100.
