Stock and Watson Indicator Report

March 2000


The Experimental Index of Coincident Indicators (XCI) rose to 241.8 in March from 241.4 in February and 241.3 in January, based on the most recently available data. Over the three months from December to March, the XCI grew 4.1% at an annual rate, while during the three months from September to December, the XCI grew 6.1% at an annual rate. Over the six months from September to March, the XCI grew 5.1% at an annual rate.

The Experimental Leading Index (XLI) for March is 3.4. 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 March to September. Because XCI growth has averaged approximately 3% annually since 1960, the March XLI forecasts continued growth well above its historical average rate.

Of the indicators used to calculate the XLI, three made a positive contribution to the index, relative to trend: manufacturers' unfilled orders; part-time employment due to slack work; and the yield on 10-year U.S. Treasury bonds. Three of the indicators made negative contributions to the index, relative to trend: housing authorizations (building permits); exchange rates; and the spread between the yield on 10-year vs. 1-year U.S. Treasury bonds. The premium on 3-month commercial paper over 3-month U.S. Treasury bills made no net contribution, 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 2% in March, indicating a 2% probability that the economy will be in a recession in September.

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 8% probability that the economy will be in a recession in September, slightly higher than the XRI.

Figure 4 shows the probability that the economy will be in a recession during each of the months from March to September, computed using data through March. Based on the data through March for the variables in the XRI, the probability that the economy was in a recession in March is 1%, the probability of being in a recession in April is 1%, and the probability of being in a recession in September is 2%. Based on the variables in the XRI-2, the probability that the economy was in a recession in March is 1%, the probability of being in a recession in April is 1%, and the probability of being in a recession in September is 8%.
