What it means
Services make up most of the economy in many developed countries, so the services PMI is often watched even more closely than the manufacturing version. The "flash" release comes out about a week before the end of the month, using the large majority of survey responses collected so far.
A final reading follows a few days later once every response has been counted. Unlike the manufacturing PMI, which blends five sub-indices, the headline services PMI is usually based on a single question about business activity.
Managers are asked whether the volume of activity is higher, the same or lower than a month earlier. The answers are converted into one index number.
The calculation treats each answer in a simple way. Firms reporting an increase count fully, firms reporting no change count as half, and firms reporting a decrease count as zero.
This is why a result of 50 means the number of firms reporting increases is balanced by the number reporting decreases. The survey also asks about new business, employment, input costs and prices charged, and these sub-indices are often published alongside the headline.
Many analysts pay close attention to the price indices, because rising service prices can signal inflation pressure. Central banks and economists use these details when judging the next move in interest rates.
For a business, the flash services PMI offers a quick read on customer demand and confidence. A sharp fall might warn of weaker spending on travel, professional fees or advertising.
Remember that the figure is based on opinion, is seasonally adjusted, and can be revised when the final data arrive. It also helps to look at the trend rather than a single month.
A reading that has moved from 49 to 51 to 53 over three months tells a clearer story than one surprise number, and a long run above 50 with a falling trend can still signal that growth is fading. Smoothing the data over a quarter helps to avoid overreacting to noise.
In practice
Real-world examples.
Example
A bond trader sees the flash services PMI drop to 48.5 from 51.2. She expects the central bank to be less worried about inflation and buys government bonds before the final number is out.
Example
A hotel chain's finance team compares its own bookings with the flash services PMI. The index shows broad growth, so the team reviews whether its own weaker results reflect local issues such as pricing or a refurbishment rather than the wider market.
Example
A consulting firm planning its hiring for the next quarter watches the services employment sub-index. A reading above 50 gives the managing partners the confidence to recruit two additional analysts.
Formula
Calculation
Services PMI (business activity) = % of firms reporting higher activity + (0.5 x % of firms reporting no change)
Suppose a flash survey of 200 service firms finds that 80 report higher activity (40%), 90 report no change (45%) and 30 report lower activity (15%). Then the index = 40 + (0.5 x 45) = 40 + 22.5 = 62.5. The reading is well above 50, which signals strong growth in the services sector that month.Case study
Seen in the real world.
Northgate Advisory is an illustrative, fictional accounting and consulting firm that depends on clients' willingness to spend on projects. Its finance partner began reading the flash services PMI each month and compared the new business sub-index to the firm's own enquiry numbers.
When the flash reading slipped from 54 to 50.5 and the new business component fell faster, she asked her team to review proposals in the pipeline. The firm brought forward some client conversations and moved a planned office expansion back by one quarter.
The following quarter, client spending did slow, and Northgate avoided taking on costs it could not cover. The illustrative takeaway is that a survey can warn of a turn early, as long as it is used alongside your own figures such as enquiries, proposals sent and the share of proposals won.
Watch out
Common mistakes.
- Assuming the flash services PMI covers every service firm, when it is based on a sample of businesses.
- Believing a reading of 60 means the sector grew by 60%, when the index only shows how broadly firms reported growth.
- Ignoring revisions, which can move the headline number between the flash and final releases.
Questions
People also ask.
What is the difference between the flash and final PMI?
The flash is an early estimate using most of the responses, while the final includes every response collected for the month.
Why do markets care about it?
It is one of the earliest indicators of economic momentum, so it can shift expectations for interest rates, currencies and share prices before official data on output and spending are published.
Does the services PMI include retail?
Coverage depends on the survey provider, but most services PMIs cover areas such as finance, transport, hospitality, business services and consumer services.
