Covid broke supply chains. Now on the mend, can they withstand another shock? – CNN

by admin on January 15, 2023


The pandemic dislodged the global supply chain, hurling once smoothly running businesses, industries and economies into a state of disarray.

After almost three years of enduring wild swings and extremes, the system is slowly getting up to speed and into better sync: Ocean freight timelines are on a steady decline, ports are less congested, labor strikes have been narrowly averted, product and worker shortages have eased, prices have fallen, warehouses are full (maybe too full), friendshoring,nearshoring and reshoring efforts have accelerated and China has lifted its “zero Covid” policy.

“We’ve had a fundamental shift that started about six months ago,” said Timothy Fiore, chair of the Institute for Supply Management. “There are certain components, like integrated circuits [and] microcontrollers, that still are impacting manufacturers’ ability to flow material. But, by and large, the pressure has come off.”

However, plenty of potential roadblocks still loom large.

Globally, developments in China and Ukraine remain ongoing question marks, especially if the manufacturing megapower suffers another setback or lockdown, or if conditions worsen with Russia’s war in Europe.

Domestically, exports have weakened and the state of consumer demand remains a wild card, said Phil Levy, chief economist with freight forwarder and consultancy firm Flexport.

“I would not describe this as a machine that’s humming along at the moment,” he said. “It’s more getting its bearings and trying to figure out what’s next.”

Among the potential bottlenecks: Warehousing capacity in certain locales, notably Southern California, is pretty near full, he said. Additionally, the inland distribution network — especially rail and areas where transfers are made from one mode to another — has experienced some challenges, he said.

The system isn’t yet at a steady state where businesses have a good sense of how long it will take for production, shipping and, ultimately, selling.

“I don’t think we have that,” Levy said. “There’s still a lot of uncertainty about how long it takes to move stuff. When we see the warehouses piled full, is this because demand is too low? Is it because people moved stuff too early? So there’s a lot of stuff that’s still sorting out.”

Returning to normal

Supply chain activity has yet to normalize, but it’s returning to pre-pandemic trajectories, said Zac Rogers, assistant professor of operations and supply chain management at Colorado State University.

“There’s a sort of reaction-overreaction pattern that always tends to happen anytime there’s a major disruption,” Rogers said. “And Covid is the major-est disruption we’ve had.”

Early in the pandemic, businesses canceled orders, believing consumer spending would be crushed. However, trillions of dollars were injected into the economy to try to keep consumers and businesses afloat. Americans, stuck at home with fewer outlets for discretionary spending, turned to e-commerce for their shopping.

The surge in demand for finished goods at a time when supply was severely limited in part due to pandemic-related labor shortages and shutdowns —notably of cities, factories and manufacturing hubs in China — knocked the global logistics system out of whack.

Ports grew congested, lead times got lengthy, and costs climbed considerably higherasshortages spiked throughout the supply chain.

“Everyone way over-ordered, and around February and March of [last] year, everything got here — pretty much right in time for the invasion of Ukraine,” Rogers said.

Gas prices and inflation soared, putting a huge dent in consumer spending.

“The challenge for the last 10 months in supply chains has been to try to thread the needle between bringing inventories down to a reasonable level, while also not overreacting, yet again, and [landing] back into a shortage situation,” he said. “We’re getting back toward the trend line in a way that we haven’t in the last few years.”

Reshoring and smoother flows

Helping that along is that supply chains are far more resilient now than they were at the end of 2019, Rogers said.

“In 2019, we had basically all of our chips in on one hand, which was, things are built in East Asia, come on a boat through the ports in Southern California, they get on trains that go to Chicago and then on other trains or trucks to distribute to the East Coast,” he said.

And while it’s nearly impossible to divorce from China, companies are embracing different paths for the supply chain, whether it be in Vietnam, Bangladesh, Central America or domestically, Rogers said.

“Because of that, supply chains are not as brittle as they were three years ago,” he said. “And so if there is another shock — particularly if there’s a China-centric shock — I think we’ll be able to absorb it a little better than we had. … But you can’t price in something like the invasion of Ukraine or a viral outbreak that shuts down the world — no systems are built to handle that smoothly.”

Rogers is also a researcher and co-author of the Logistics Managers’ Index, a monthly survey of supply chain executives conducted by a team of university researchers and the Council of Supply Chain Management Professionals.

The index’s December reading — which measures inventory levels and costs; warehousing capacity; utilization and prices; and transportation capacity, utilization and prices — came in at 54.6, a 1-point increase following eight months of declines.

The majority of the LMI metrics were in the range of 40s, 50s and 60s, Rogers said, noting it’s the first time since the onset of the pandemic that the indices haven’t been in the 70s or 80s.

“If you’re in 40, that’s contraction, but 50s are normal, healthy rates of growth,” he said. “There could be another huge black swan event in a month that throws everything upside down; but for right now, it seems like respondents are predicting steadiness in the supply chain.”

If anything, the pandemic’s shock to the supply chain should be a wake-up call, said Jack Buffington, director of supply chain and sustainability at First Key Consulting and assistant professor of supply chain management at the University of Denver.

“I would categorize it as ‘efficiently broken,’” said Buffington, whose own book about supply chains, “Reinventing the Supply Chain: A 21st Century Covenant with America,” had its release delayed due to supply chain issues.

“All supply chains really are is supply and demand, and there’s been so much disruption in materials and consumer demand related to labor and inflation and geopolitics,” he said. “Inherently, the foundation of the model is broken in comparison to what the demands are for today. The complexities related to a globalized supply chain, human systems aren’t capable of handling it.”

He added: “Covid wasn’t the cause of the problems with the supply chain, it was a trigger to show how bad it was,” he said.
