Walk into any U.S. store these days and you are likely to see empty shelves. Shortages of virtually every type of product – from toilet paper and sneakers to pickup trucks and electronics – are showing up across the country. Looking for a book, bicycle, baby crib or boat? You may have to wait weeks or months longer than usual to get your hands on it. This may seem a little odd to some Americans given the U.S. has been living with the COVID-19 pandemic for over 19 months. Shouldn’t supply chains stressed by the onset of the pandemic have worked out their kinks by now? As someone who conducts research and teaches on the topic of global supply chain management, I believe there are four primary – and interrelated – reasons for the continuing crunch. And unfortunately for many, they will not be resolved by the holidays.
1. Consumer demand soars
When the pandemic first slammed into American shores in March 2020, companies were already preparing for a prolonged recession – and the typical resulting drop in consumer demand. Retailers and automakers, many of which had to close due to lockdowns, canceled orders from suppliers. It made sense at the time. By April, the unemployment rate reached 14.8 percent, its highest level since the Labor Department began collecting this data in 1948. And consumer spending plunged.
But something strange happened by the end of the summer of 2020. After the initial shock, consumer spending began to rebound and was nearing pre-pandemic levels by September, in no small part thanks to the trillions of dollars in aid Congress was showering on the economy and people. By March 2021, consumers were again spending record amounts of money on everything from new computers and chairs for home offices to bikes and sporting goods as people sought safer ways to get around and entertain themselves. (Sales of luxury goods have also steadily grown all the while.)
Demand for consumer goods has only climbed since thenm and while it is generally good for businesses and the U.S. economy, the supply chain for most products has not been able to keep up – or even catch up.
2. Missing workers
Even as demand from consumers in the U.S. and elsewhere surges, low vaccination rates at key points in the global supply chain are causing significant production delays. Less than a third of the global population has been fully vaccinated from COVID-19 – and almost 98 percent of those people live in wealthier countries. Low levels of vaccinated workers in important manufacturing hubs, such as Vietnam, Malaysia, India and Mexico, for instance, have caused production delays or reduced capacity. Vietnam, for example, plays a key role in the apparel and footwear industry, as the second-largest supplier to the U.S. of shoes and clothes following China. Less than 12 percent of its population is fully vaccinated, and many factories have been shuttered for long periods due to outbreaks and government lockdowns. Failure to vaccinate more people in developing countries more quickly will likely mean worker shortages will continue to plague supply chains for many months to come.
3. Shipping container shortage
Americans’ insatiable demand for more stuff has another consequence: Empty containers are piling up in the wrong places. Large steel shipping containers are pivotal to global supply chains. In 2020, the U.S. imported more than $1 trillion worth of goods from Asian countries. And most of those consumer goods make their way to the U.S. on container ships. To get a sense of the scale, a single container can hold 400 flat-screen TVs or 2,400 boxes of sneakers.
But many of those containers making their way to the U.S. do not have a way to get back to Asia. The reasons involve a lack of workers, complicated customs procedures and a host of other problems. The shortage has driven up the price of containers fourfold over the past year, which in turn is contributing to higher consumer prices.
4. Clogged ports
All these problems are contributing to another challenge: U.S. ports have become extremely backed up with ships waiting to unload their cargo. A large ship can hold 14,000 to 24,000 containers. That means one ship waiting to make port could hold as much as 5.5 million televisions or 33.6 million sneakers.
Right now, more than 60 container ships are anchored in the ocean off the Ports of Los Angeles and Long Beach, unable to unload their stuff. Ports are also clogged in New York, New Jersey and other locations globally. Normally, there is no wait for these ships to dock and unload their cargo. But the record demand for imports and shortages of truckers, containers and other equipment has caused substantial delays.
Before COVID-19, global supply chains worked pretty efficiently to move products all around the world. Companies utilized a just-in-time philosophy that minimized waste, inventories and expenses. The cost of that, of course, is that even small problems like a hurricane or a factory fire can cause disruptions. And the pandemic has caused a meltdown.
