Chemical Activity Barometer fell in May

Written on: June 2, 2020 by SprayTM

The Chemical Activity Barometer (CAB), an economic indicator created by the American Chemistry Council (ACC), fell 5.4 percent in May on a three-month moving average (3MMA) basis following a 5.4 percent decline in April. On a year-over-year (Y/Y) basis, the barometer fell 12.4 percent in May.

The unadjusted May data shows a 0.3 percent decline following a 6.3 percent drop in April and an 8.9 percent decline in March. The diffusion index fell from 35 percent to 29 percent in May as production declines became more widespread. The diffusion index marks the number of positive contributors relative to the total number of indicators monitored. The April CAB reading was revised upward by 0.37 points and the March reading was revised downward by 0.08 points.

“The May CAB reading is consistent with a recession, but given the small unadjusted decline of only 0.3 percent, one that may bottom out,” said Kevin Swift, chief economist at ACC.

The CAB has four main components, each consisting of a variety of indicators: 1) production; 2) equity prices; 3) product prices; and 4) inventories and other indicators.

Production-related indicators declined in May. Trends in construction-related resins, pigments and related performance chemistry were negative, as were resins used in appliances, light vehicles, machinery and other durable goods. Plastic resins used in packaging and for consumer and institutional applications were mixed. Performance chemistry was negative and U.S. exports were weak. Equity prices are improving and product and input prices are firming. Inventory and other supply chain indicators were negative.

The CAB is a leading economic indicator derived from a composite index of chemical industry activity. Due to its early position in the supply chain, chemical industry activity has been found to consistently lead the U.S. economy’s business cycle, and this barometer can be used to determine turning points and likely trends in the broader economy. Month-to-month movements can be volatile, so a three-month moving average of the CAB reading is provided. This provides a more consistent and illustrative picture of national economic trends.

Applying the CAB back to 1912, it has been shown to provide a lead of two to 14 months, with an average lead of eight months at cycle peaks as determined by the National Bureau of Economic Research. The median lead was also eight months. At business cycle troughs, the CAB leads by one to seven months, with an average lead of four months. The median lead was three months. The CAB is rebased to the average lead (in months) of an average 100 in the base year (the year 2012 was used) of a reference time series. The latter is the Federal Reserve’s Industrial Production Index.

The CAB comprises indicators relating to the production of chlorine and other alkalies, pigments, plastic resins and other selected basic industrial chemicals; chemical company stock data; hours worked in chemicals; publicly sourced, chemical price information; end-use (or customer) industry sales-to-inventories; and several broader leading economic measures (building permits and new orders). Each month, ACC provides a barometer number reflecting activity data for the current month, as well as a three-month moving average. The CAB was developed by the Economics Department at ACC.

Current-month, unadjusted readings of the CAB are based on high-frequency weekly and daily data. For example, we use equity data as of the Thursday before the release date. Using mid-month data can lead to large revisions if conditions appreciably change in the second half of the month. We have moved the release dates for the CAB to the last Tuesday of each month. We hope this will minimize the revisions.

The CAB is designed and prepared in compliance with ACC’s Antitrust Guidelines and FTC Safe Harbor Guidelines; does not use company-specific price information as input data; and data is aggregated such that company-specific and product-specific data cannot be determined. Note: ACC has strived to prepare this publication to provide the best available information.
