August 2021 ISM-Houston Business Report
Houston PMI at 57.5
(Houston, Texas) – According to Houston area supply chain executives, overall economic activity in Houston expanded again in August. The overall ISM-Houston PMI diffusion index rose modestly. Manufacturing activities strengthened significantly. Services activities, while continuing to point to growth, slowed minimally.
The Houston Purchasing Managers Index rose 0.3 points to 57.5 during the month. Improvement in the employment index was offset by declines in the sales/new orders and lead times indices. These three indicators have the strongest direct correlation with the economic activity in Houston. The sales/new orders index fell 4.1 points to 54.6. The lead times index fell 0.8 points to 63.1. The employment index rose 4.8 points to 57.9. The Finished goods inventory index, the underlying indicator that has the strongest inverse correlation with economic activity, rose 1.9 points to 46.6, continuing to point to economic expansion.
The three-month forecast for the Houston PMI rose 0.8 points to 56.2. A higher production index more than offset lower sales/new orders and prices paid indices to account for this gain. These indices have a strong direct correlation with economic activity at the three-month forecast horizon.
On an industry specific basis, oil & gas, construction, manufacturing, transportation, healthcare, new and existing home sales, professional services, and leisure and hospitality reported strong expansion. The three-month forecast continues to predict expansion, primarily due to the strength of the sales/new orders, production, and prices paid indices.

Background on the ISM-Houston Business Report and HPMI Calculation Methods
The Houston Purchasing Managers Index has been included as an integral part of the ISM-Houston Business Report since the Houston chapter of the Institute for Supply Management started publication of this document in January 1995. The report and index are published monthly as the primary deliverables from a survey of Houston area Supply Chain leaders regarding the status of key activities believed to provide insight into the strength of the economy. The respondents come from diverse organizations including construction, energy, engineering, health care, durable and non-durable goods manufacturing, financial and business services, wholesale and retail trade, and utilities related companies.
The Houston Purchasing Managers Index is determined from diffusion indices of the eight indicators of economic activity covered by the ISM-Houston Business Survey and Report. These underlying indicators are sales or new orders, production, employment, purchases, prices paid for major purchases, lead times from sellers, purchased materials inventory (raw materials and supplies), and finished goods inventories. The respondents to the survey report the direction of each these activities as either up, the same or down in comparison to the previous month. An index for each of these areas is then calculated by subtracting the percentage of respondents that sight a negative shift from the percentage that sight a positive shift. For indicators that are positively correlated with economic growth, this results in an underlying index that points to expansion when it is above zero. Indicators that are negatively correlated with growth point to expansion when they are below zero.
The final Houston PMI is calculated by applying optimal regression factors to each of the eight underlying indicators noted above. These regression factors are determined using standard regression techniques comparing these underlying indicators to the Houston-The Woodlands-Sugar Land Business Cycle Index (Houston BCI), which is reported on a monthly basis by the Federal Reserve Bank of Dallas. This top-level index is converted to a 0 to 100 scale to match that of the national Purchasing Managers Index® (PMI®) which is published monthly by the Institute for Supply Management® (ISM®). Readings over 50 for the HPMI generally indicate manufacturing expansion in the Houston in the near term and readings below 50 show coming manufacturing contraction.
It is important to note that the manufacturing breakeven HPMI does not equate to the breakeven point for the overall Houston economy. ISM-Houston periodically reviews the capability of its correlations and adjusts the regression factors when appropriate. The most recent revision occurred as a result of a review undertaken during the third quarter of 2018, which determined that changes in the Houston economy over the last decade have shifted the intercept of the correlation, causing a neutral Houston PMI to no longer align with a neutral Houston BCI. A Houston PMI of 45 points now equates to a neutral Houston economy as measured by the Houston BCI. A similar offset between the National PMI and the National economy has existed for some time.
