Stock and Watson Indicator Report

August 2002


The Experimental Index of Coincident Indicators (XCI) was 236.0 in August, the same as its value in July, based on the most recently available data.  During the three months from May to August the XCI rose by 2.4% at an annual rate.  During the previous three months from February to May, the XCI rose by 1.5% at an annual rate.  Over the entire six months from February to August, the XCI therefore rose 2.0% at an annual rate.

A calculation based on the variables in the XCI indicates that the probability that the economy was in a recession in August is 5%. Historical values of this Experimental Concident Recession Index (XRI-C) are shown in Figure 4.

The Experimental Leading Index (XLI) for August is 3.7. This index, based on seven leading indicators, is a forecast of the percentage growth of the XCI (at an annual rate) over the next six months, from August to February 2003.

Of the indicators used to calculate the XLI, six made a positive contribution to the index, relative to trend: housing authorizations (building permits); manufacturers' unfilled orders; exchange rates; the yield on 10-year U.S. Treasury bonds; the premium on 3-month commercial paper over 3-month U.S. Treasury bills; and the spread between the yield on 10-year vs. 1-year U.S. Treasury bonds. One of the indicators, part-time employment due to slack work, made a negative contribution to the index, relative to trend.

Based on the most recent data, the Experimental Recession Index (XRI), which estimates the probability that the economy will be in a recession six months later, was 5% in August, indicating a 5% probability that the economy will be in a recession in February 2003. The alternative experimental recession index (the XRI-2), which is based on seven leading indicators that do not include interest rates or interest rate spreads, estimates a 9% probability that the economy will be in a recession in February 2003.
