Supply Chain Shocks of the 2020s

The COVID-19 pandemic revealed how stretched global supply chains had become. In early 2020 factory shutdowns in China halted parts supplies worldwide, while shortages of masks and medical equipment exposed dependence on a few producers. As lockdowns eased, consumers in rich countries shifted spending from services to goods, overwhelming ports and shipping: container freight rates on major routes rose roughly tenfold, and dozens of ships waited offshore at Los Angeles and Long Beach. A shortage of semiconductors forced carmakers to cut output.

In March 2021 the container ship Ever Given blocked the Suez Canal for six days, delaying hundreds of vessels. Then Russia's 2022 invasion of Ukraine disrupted exports of wheat, sunflower oil, fertilizer and energy, raising food and fuel prices globally. These shocks contributed to the inflation surge of 2021–23. Governments and firms responded by building inventories, diversifying suppliers and subsidizing domestic production of critical goods, debates that continue.
