Houston Economy Strengthens Further
Employment Starts to Return
By Ross S. Harvison, CPSM
(Houston, Texas) – According to Houston area supply chain executives, overall economic activity in Houston expanded in February for the ninth month. Manufacturing activities expanded for the third month and services activities have now expanded for the last seven months.
The Houston Purchasing Managers Index rose 1.7 points to 54.3 during the month. The employment index joined the sales/new orders and lead times indices in pointing to expansion. These three underlying indicators that have a strong direct correlation with the economy. The sales/new orders index fell a modest 0.4 points to 56.6, its ninth month of indicating expansion. The lead times index rose 1.5 points to 57.4, also its ninth month pointing to expansion. The employment index rose 2.9 points to 50.8. The employment index has not indicated expansion since early last year. Finished goods inventory, the underlying indicator that has the strongest inverse correlation with economic activity, fell 3.5 points to 47.9, indicating a modest expansion signal.
The three-month forecast for the Houston PMI fell minimally to 54.1. An improvement in the lead times index was offset by lower sales/new orders and production indices. These indices have a strong direct correlation with economic activity at the three-month forecast horizon.
On an industry specific basis oil & gas joined construction, manufacturing, transportation, and healthcare in reporting expansion at a strong pace. All other sectors reported near neutral. The three-month forecast continues to predict further expansion primarily due to the strength of the sales/new orders, production, and prices paid indices.

- This sector reported flat this month after strong improvement last month; the purchases index indicated weakness while process paid index showed strength; all other indices were near neutral
- As we continue to increase the amount of COVID-19 vaccinations, general purpose syringes are in very high demand; these syringes are used for all other types of vaccinations; we are engaging the manufacturers to ensure that we remain on their respective production schedules; it is anticipated that this high demand will continue through the end of the calendar year
- This sector continues to report strength with the sales, purchases, and lead times indices all continuing to pointing to expansion; the employment index remains near neutral
Trend of Underlying Indicators
The Houston PMI is based on diffusion indices for eight underlying indicators. The net value of each indicator is simply the percentage of respondents who cite a positive shift from the previous month minus the percentage who cite a negative shift. The diffusion index is calculated based on the percent of respondents reporting higher results plus one-half of those responding the same with a seasonal adjustment based on an X13 ARIMA forecast. Values above 50 for Sales/New Orders, Production, Employment, Prices Paid, and Lead Times generally point towards expansion and values below 50 signal contraction. Note that the Prices Paid Index may not follow this trend late in an economic expansion. The Inventory measures have an inverse correlation at most forecast horizons, meaning that values below 50 point to expansion and values above point to contraction. The Purchases index is inversely correlated with economic activity at the three-month forecast horizon.
The sales/new orders index continues to point towards moderate to strong expansion. Oil & gas, manufacturing, and health care showed significant strength. No sector reported contraction in this index.
The production index pointed to continued expansion at a slower pace. Oil & gas joined non-durable goods manufacturing in showing strength. All other sectors reported near neutral.
This employment index rose to above neutral for the first time since early last year. Durable goods manufacturing reported strength and non-durable goods rose to just below neutral. All other sectors reported at neutral.
This index rose this month to continue indicating expansion. Non-durable goods joined O&G, durable goods, and health care reporting it as expanding. Construction and professional services continue to report it as contracting.
The prices paid index rose to indicate stronger expansion. Real estate, construction, durable goods manufacturing, professional services, and health care reported this index as expanding. All other sectors reported near neutral.
The lead times index rose further this month. Real estate joined oil & gas, construction, manufacturing, and health care in reporting this index as expanding at a high rate. All other sectors reported near neutral.
The purchased goods inventory index was again below neutral. Construction and durable goods manufacturing reported these inventories as contracting. All other sectors were near neutral.
Finished Goods Inventories
The finished goods inventory index showed further contraction. O&G, construction, and manufacturing reported these inventories as contracting. All other sectors reported near neutral.
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.
