3 Key Indicators Supply Chain Professionals Watch, Analyze, and React To
This issue's key takeaways:
- An abundance of data makes it hard to differentiate what’s useful and what’s noise.
- Supply chain risk management professionals constantly track a variety of data sets to inform purchasing decisions
- For CSCOs, narrowing the noise down to these three signals turns market data into faster, more confident sourcing and inventory decisions
Risk Trivia: What sports do we love most?
Asking what the most popular U.S. sport is in 2026 feels too easy, like asking who the current president is or what movie currently starring Matt Damon is based on a famous Greek poem.
Football continues to dominate, and indeed is ranked as the #1 most popular U.S. sport to watch.
Today’s trivia question is: what sport, dear friends, according to a recent Gallup poll, is #2?
Snapshot: How chief supply chain officers respond to these 3 key economic signals
By John Donigian, Managing Director, Supply Chain Risk & Procurement
Data is like streaming content: the more there is, the harder it is to figure out what's worth watching. Sifting through dozens of metrics is like scrolling an endless queue of shows; a daunting exercise that often ends the same way: defaulting to whatever's trending instead of what actually matters.
However, evaluating data, unlike finding a good show, is a core feature of business leadership, and shapes how important decisions get made every single day. Each business has to decide what to value, and what to ignore, in order to operate decisively and not go crazy from data overload.
While supply chain risk management professionals analyze dozens of metrics and data points, today’s newsletter will focus on the following:
- Highlight three economic indicators supply chain professionals are watching
- Review what the data in these metrics show
- Discuss how professionals can respond when these key signals fluctuate
Purchasing manager’s index (PMI)
What it shows
PMI is a monthly survey of supply chain managers at private companies' expectations in terms of production, orders, deliveries, and employment. PMI ranges from 0 to 100; above 50 indicates expansion, below 50 means contraction. A PMI of 50 signals no change in the environment.
The Institute for Supply Management (ISM) issues a PMI for manufacturing, services, and healthcare sectors, while the global manufacturing PMI, compiled monthly by S&P Global, represents 90% of global GDP through surveys of over 28,000 companies.
The S&P Global PMI is 52.3 as of August 2026.
Why PMI is valuable
As a single metric, PMI is useful because it offers companies a concise glimpse into the overall business environment and where it is headed.
Unlike GDP reports or earnings calls, PMI provides corporate managers, suppliers, and investors with early warning signals of economic trends to come, and helps chief supply chain officers (CSCOs) make decisions based on real-time information instead of data that could be months old.
How supply chain professionals should respond
When PMI is rising, as it was in August, that's normally a green light for CSCOs to build inventory and lock in supplier capacity early. Though, as the next metric shows, the picture this August is more complicated than PMI alone suggests.
When PMI is falling instead, the read is different: demand is cooling, so the move is to trim inventory, delay non-essential purchase orders, and avoid getting stuck with excess stock. It's also a good time to renegotiate pricing, since suppliers have more slack.
Supplier delivery time
What it shows
A sub-index of PMI, supplier delivery time tracks how long it takes goods to arrive. Supplier delivery time is measured on a 0 to 100 scale, but with an inverted score that pairs a higher number with slower delivery times.
For example, a delivery times measurement above 50 is a sign of a slower, lengthening delivery environment that features supply chain disruptions.
The supplier delivery time measurement for August 2026 according to the US ISM Manufacturing Supplier Delivery Index, stands at 59.30, an uptick from July and a sign that delivery times are increasing.
Why supplier delivery time is valuable
This metric more directly signals physical bottlenecks and delays and can be especially useful in determining industry-wide supplier issues that might lead to inventory shortages. Ongoing trade wars and geopolitical conflicts are contributing to the difficult delivery environment behind that reading.
How supply chain professionals should respond
The increase in supplier delivery times calls for a more nuanced look at the PMI rating. The rising PMI index for August indicates demand is solid and all is well; but, the supplier delivery time signals congestion and a pipeline stressed by delays and scarcity.
For CSCOs, responding to high delivery times can include adding safety stock on critical items, vetting a pool of backup suppliers, and possibly dual-sourcing from suppliers with better track records.
Container freight spot rates
What it shows
Shipping costs provide an overview into how demand is being met by capacity, and what that says about a supply chain’s near future. Container freight spot rates have been high and remain so, driven by peak season demand combined with earlier-than-normal holiday season orders.
Tariffs, shipping route congestion, and rising fuel costs have also contributed to the uptick in rates.
Why container freight spot rates are valuable
Container freight spot rates are a key factor in sourcing and contract timing: when rates spike, as they have recently, carriers gain leverage; when rates fall, it's an opening to renegotiate freight terms.
How supply chain professionals should respond
The higher rates mean that carriers have more leverage than CSCOs, who should be looking to lessen the financial uncertainty of the spot market by locking in longer-term freight contracts. Additionally, CSCOs can try to obtain more favorable volume pricing by consolidating shipments.
Trivia Answer: Basketball
According to Gallup, football reigns supreme, with over 31% of respondents naming it their top sport to watch. Basketball came in second at 11%, while baseball was next at 10%.
Soccer was next with 9%, right at the heels of basketball and baseball. Keep in mind, soccer didn’t exceed 2% in this Gallup survey until 2005, so it’s come a long way in the past twenty years.
These three signals are macro-level early warnings — they tell you the environment is shifting, but not which specific suppliers in your base can absorb that shift and which can't. That's the gap supplier-level financial health closes: pairing macro indicators like these with supplier-specific financial monitoring is what turns a market signal into an actual sourcing decision.
