Why supply-chain problems aren’t going away

SUPPLY CHAINS have seldom featured in companies’ earnings reports over the three decades since globalisation took off in earnest, save for the occasional mention of the benefits of low costs and lean inventories. This earnings season, though, covid-induced shortages are among the first problems mentioned by many firms. The Omicron variant has worsened the logjams by forcing workers, in many industries and the logistics business that weaves them together, to quarantine. And shortages of both staff and materials are contributing to inflation, raising costs across the board.
