Companies are still trying to sort out their inventory levels and strategies after the economy screeched to a halt during the pandemic and then quickly restarted.
At this time last year, firms were scrambling to figure out how to store inventory that could no longer be sold due to COVID lockdowns. Now the New York Times is writing articles titled “How the World Ran out of Everything,”1 as we deal with shortages ranging from fireworks2 to semiconductors.3
When I wrote the inventory update for Supply Chain Quarterly’s 2020 State of Logistics issue, I reported that the retail inventory-to-sales ratio for April 2020 was 1.67, one of its highest readings ever and the highest since 1995. One year later, the inventory-to-sales ratio comes in at 1.07—the lowest reading ever by some distance. While it may not sound like it, the movement of 0.6 points is the largest one-year movement in the history of this index. However, this does not mean that inventory is lower; it is actually the opposite, as overall levels are up by 1.3% from the same time last year (and up 4.7% from their nadir in July).
The difference lies in retail sales being 48.1% higher in April 2021 compared to April 2020 due to the reopening of the economy and the ending of COVID lockdowns. Retail sales have climbed every month since April, putting even more pressure on inventories. This trend helps to explain the ongoing shortages, delivery delays, and price spikes being reported across multiple industries. Many businesses have gone from standing still at this time a year ago to sprinting as quickly as they can in order to keep up with burgeoning consumer demand.
Side effects of pent-up demand
This shift has been largely driven by pent-up demand from U.S. consumers as they emerge from pandemic shutdowns. The U.S. economy grew at a rate of 6.4% in Q1 2021, and economists expect consumer spending could be up 9% this year—the highest increase since 1946—the year after the end of World War II. Savings were at 12.4% in May 2021, nearly 50% higher than the 8.3% registered in February 2020 before the lockdowns.4 The excitement over this rapid recovery has been somewhat tempered by fears of inflation, as consumer prices were up 5% for the 12-month period ending in May—the sharpest increase since 2008.5
These costs can be largely explained by the pressure that the sudden shutdown and rapid recovery has placed on the logistics industry. The Logistics Managers’ Index (LMI) measures the growth/contraction of key logistics metrics on a monthly basis (see Figure 1). The month-to-month movement for inventory levels (yellow line), inventory costs (purple line), available warehouse capacity (blue line), warehouse prices (green line), transportation capacity (gray line), and transportation costs (red line) are presented in the figure. When interpreting this figure, any value over 50.0 (represented by the dashed, black line) indicates month-to-month growth, and any value below 50.0 indicates contraction.
At the outset of COVID-19 (February 2020), inventory levels were down slightly (as they often are post-Q4), and inventory costs, warehouse capacity, and warehouse prices were all growing at moderate rates. As with most other things, the COVID-related lockdowns flipped these metrics on their heads. Inventory costs have increased considerably over the last 15 months. Interestingly, inventory levels have grown fairly steadily, eschewing the sharp growth or contraction patterns seen with every other metric in the figure. This moderate rate of inventory growth combined with the sharp growth of logistics costs and shift in inventory-to-sales ratios suggest that a volume of inventory is moving through supply chains at a high velocity. Evidence of the velocity is present in the secondary (or aftermarket) market, which was up $40 billion in 2020 to an all-time record of $671 billion—equivalent to 3% of U.S. gross domestic product (GDP).
This velocity is also reflected in the tightening capacity and rising costs presented in the figure. In the history of the LMI, warehouse capacity had never registered as contracting until March 2020. Since then, it has only registered growth once, in August 2020. Transportation capacity, after a brief spike in Spring 2020 during the height of lockdowns, has also contracted for the last year of readings. This lack of available capacity has led to a spike in logistics costs, with transportation prices above 80.0 on the index for a full year and both inventory and warehouse costs setting all-time index highs multiple times over the last year, including in June 2021.
The high costs of warehousing and transportation are relevant here because they directly impact the ability of firms to maintain a constant level of supply and meet customer demand. The lack of available transportation has impacted both international and domestic supply. There are stories of some low-margin items being pushed back to later sailings multiple times due to a lack of ocean shipping capacity. In some cases, this has doubled or tripled lead times for international shipping and increased the costs by a factor of 10. Demand for international shipping has led to the Port of Los Angeles setting an all-time record for imports for the year ending on June 30, exceeding 10 million TEUs (twenty-foot equivalent units) for the first time ever.6 This record-breaking volume has led to well-documented delays at the ports, with ships waiting weeks to be unloaded instead of days.
A similar capacity crunch exists domestically. The benchmarking and analytics company FreightWaves’ Tender Rejection Index, which tracks how many potential truckloads (tenders) are being rejected, has hovered around 25% since Fall 2020. This figure indicates that for every four loads that need to be moved, only three are being picked up. Rejected tenders have led to further shipping delays as well as spot rates increasing 67% for dry vans and 63% for flatbeds year-over-year. As a result of all these delays, firms have had a tough time managing inventory levels. Instead of getting a consistent stream of just-in-time (JIT) inventory flowing in at a level they can handle, inventory arrives in waves with nothing coming in for weeks and then big spikes suddenly overwhelming capacity.7
Digging out of this hole will take time. When asked to predict logistics activity over the next 12 months, LMI respondents predicted high levels of growth for warehouse and inventory costs, as well as overall inventory levels. (See Figure 2.)
Fortunately, there is some hope on the horizon, as respondents also predict growth in both available warehouse and transportation capacity over the next year. The levels of predicted growth are moderate, but they would be a relief after the last 15 months of contraction in available logistics capacity. This hope is further bolstered by the fact that LMI respondents have predicted future movements for the index with approximately 90% accuracy.
Post-pandemic strategies
Firms have gone through an unprecedented year. After the screeching halt to business as usual in 2020 and the fast restart of the economy, it is interesting to observe the different strategies firms are using to manage their inventory. For instance, some firms have moved away from long-held JIT strategies, even in industries that are JIT stalwarts, such as automotive and grocery. Grocery stores began stocking “pandemic pallets” of essential nonperishable items last year to deal with panic-buying associated with the various waves of viral outbreaks. Auto manufacturers have engaged in stock-piling and forward-buying as a way to avoid the disruptions that plagued them over the last year. Toyota outsold General Motors in the U.S. for the first time in Q2 2021 largely because they had a ready reserve of semiconductors, which allowed them to produce more vehicles.8 Of course, there can be downsides to this approach. In classic bullwhip fashion, there is now a glut of items like toilet paper and hand sanitizer that were overproduced to meet last year’s shortages.
It seems clear from the most recent indicators that consumers will not forget the lessons of the pandemic. It is important that firms do not forget these lessons either. Supply managers have always struggled to balance potential inventory shortages with overstocks. That has been even more difficult this year due to the wild fluctuations in demand. However, it has not been impossible. Many firms have reported some of their best years ever, despite the uncertain times. The companies that have been most successful over the last year are the ones with more resilient supply networks that have allowed them to adapt more quickly.
The emergence of the Delta variant epitomizes the cycle of disruptions that supply chains will always have to deal with. The firms that are the most flexible and can most deftly manage their inventory will be in the best position to deal with them.

J.B. Hunt President and CEO Shelley Simpson answers a question from the audience at the Tuesday afternoon keynote session at CSCMP's EDGE Conference. CSCMP President and CEO Mark Baxa listens attentively to her response.
Most of the time when CEOs present at an industry conference, they like to talk about their companies’ success stories. Not J.B. Hunt’s Shelley Simpson. Speaking today at the Council of Supply Chain Management Professionals’ (CSCMP) annual EDGE Conference, the trucking company’s president and CEO led with a story about a time that the company lost a major customer.
According to Simpson, the company had a customer of their dedicated contract business in 2001 that was consistently making late shipments with no lead time. “We were working like crazy to try to satisfy them, and lost their business,” Simpson said.
When the team at J.B. Hunt later met with the customer’s chief supply chain officer, they related all they had been doing for the company. “We told him that we were literally sitting our drivers and our trucks just for you, just to cover your shipments,” Simpson said. “And he said to us, ‘You never shared everything you were doing for us.’”
Out of that experience, came J.B. Hunt’s Customer Value Delivery framework. This framework, according to Simpson, provides a roadmap for creating value and anticipating customer needs.
Framework for Excellence
J.B. Hunt created the above framework to help them formulate better relationships with customers.
The framework consists of five steps:
Understand customer needs: It all starts, according to Simpson, with building a strong relationship with the customer and then using the information gained from those discussions to build a custom plan for the customer.
Deliver expectations: This step involves delivering on the promises made in that custom plan.
Measure results: J.B. Hunt believes that they are not done when freight makes it to the destination. They also need to measure how successful they were versus what the customer expected from them.
Communicate performance: This step involves a two-way exchange, where J.B. Hunt walks the customer through their performance and gets verbal agreement on whether or not they have met the customer’s needs.
Anticipate new value: Here J.B. Hunt looks at what they are hearing from their customer today and then uses that information to derive what the customer may be looking for in the future.
Simpson said the most important part of the process is the fourth step, communicating performance (perhaps reflecting the piece that went wrong in that initial failed customer relationship).
Not only can this framework be used to drive excellence in a company, but it can also be adapted as a model for driving personal excellence, Simpson said. Instead of understanding the customer needs, the process starts with understanding yourself: what your strengths and interests are. This understanding helps drive a personal development plan and personal goals for the year, which can be measured and assessed. For example, each year, Simpson gives herself a letter grade on each of her personal goals and communicates her assessment back to her boss. She has also found it helpful to anticipate where opportunities lie beyond what she is personally doing.
Confronted with the closed ports, most companies can either route their imports to standard East Coast destinations and wait for the strike to clear, or else re-route those containers to West Coast sites, incurring a three week delay for extra sailing time plus another week required to truck those goods back east, Ron said in an interview at the Council of Supply Chain Management Professionals (CSCMP)’s EDGE Conference in Nashville.
However, Uber Freight says its latest platform updates offer a series of mitigation options, including alternative routings, pre-booked allocation and volume during peak season, and providing daily visibility reports on shipments impacted by routings via U.S. east and gulf coast ports. And Ron said the company can also leverage its pool of some 2.3 million truck drivers who have downloaded its smartphone app, targeting them with freight hauling opportunities in the affected regions by pricing those loads “appropriately” through its surge-pricing model.
“If this [strike] continues a month, we will see severe disruptions,” Ron said. “So we can offer them alternatives. We say, if one door is closed, we can open another door? But even with that, there are no magic solutions.”
Turning around a failing warehouse operation demands a similar methodology to how emergency room doctors triage troubled patients at the hospital, a speaker said today in a session at the Council of Supply Chain Management Professionals (CSCMP)’s EDGE Conference in Nashville.
There are many reasons that a warehouse might start to miss its targets, such as a sudden volume increase or a new IT system implementation gone wrong, said Adri McCaskill, general manager for iPlan’s Warehouse Management business unit. But whatever the cause, the basic rescue strategy is the same: “Just like medicine, you do triage,” she said. “The most life-threatening problem we try to solve first. And only then, once we’ve stopped the bleeding, we can move on.”
In McCaskill’s comparison, just as a doctor might have to break some ribs through energetic CPR to get a patient’s heart beating again, a failing warehouse might need to recover by “breaking some ribs” in a business sense, such as making management changes or stock write-downs.
Once the business has made some stopgap solutions to “stop the bleeding,” it can proceed to a disciplined recovery, she said. And to reach their final goal, managers can use the classic tools of people, process, and technology to improve what she called the three most important key performance indicators (KPIs): on time in full (OTIF), inventory accuracy, and staff turnover.
CSCMP EDGE attendees gathered Tuesday afternoon for an update and outlook on the truckload (TL) market, which is on the upswing following the longest down cycle in recorded history. Kevin Adamik of RXO (formerly Coyote Logistics), offered an overview of truckload market cycles, highlighting major trends from the recent freight recession and providing an update on where the TL cycle is now.
EDGE 2024, sponsored by the Council of Supply Chain Management Professionals (CSCMP), is taking place this week in Nashville.
Citing data from the Coyote Curve index (which measures year-over-year changes in spot market rates) and other sources, Adamik outlined the dynamics of the TL market. He explained that the last cycle—which lasted from about 2019 to 2024—was longer than the typical three to four-year market cycle, marked by volatile conditions spurred by the Covid-19 pandemic. That cycle is behind us now, he said, adding that the market has reached equilibrium and is headed toward an inflationary environment.
Adamik also told attendees that he expects the new TL cycle to be marked by far less volatility, with a return to more typical conditions. And he offered a slate of supply and demand trends to note as the industry moves into the new cycle.
Supply trends include:
Carrier operating authorities are declining;
Employment in the trucking industry is declining;
Private fleets have expanded, but the expansion has stopped;
Truckload orders are falling.
Demand trends include:
Consumer spending is stable, but is still more service-centric and less goods-intensive;
After a steep decline, imports are on the rise;
Freight volumes have been sluggish but are showing signs of life.
CSCMP EDGE runs through Wednesday, October 2, at Nashville’s Gaylord Opryland Hotel & Resort.
The relationship between shippers and third-party logistics services providers (3PLs) is at the core of successful supply chain management—so getting that relationship right is vital. A panel of industry experts from both sides of the aisle weighed in on what it takes to create strong 3PL/shipper partnerships on day two of the CSCMP EDGE conference, being held this week in Nashville.
Trust, empathy, and transparency ranked high on the list of key elements required for success in all aspects of the partnership, but there are some specifics for each step of the journey. The panel recommended a handful of actions that should take place early on, including:
Establish relationships.
For 3PLs, understand and get to the heart of the shipper’s data.
Also for 3PLs: Understand the shipper’s reason for outsourcing to a 3PL, along with the shipper’s ultimate goals.
Understand company cultures and be sure they align.
Nurture long-term relationships with good communication.
For shippers, be transparent so that the 3PL fully understands your business.
And there are also some “non-negotiables” when it comes to managing the relationship:
3PLs must demonstrate their commitment to engaging with the shipper’s personnel.
3PLs must also demonstrate their commitment to process discipline, continuous improvement, and innovation.
Shippers should ensure that they understand the 3PL’s demonstrated implementation capabilities—ask to visit established clients.
Trust—which takes longer to establish than both sides may expect.
EDGE 2024 is sponsored by the Council of Supply Chain Management Professionals (CSCMP) and runs through Wednesday, October 2, at the Gaylord Opryland Resort & Convention Center in Nashville.
