The surging omicron variant is complicating the recovery for a world economy that continues to be wracked by supply chain chaos, worker absenteeism and faltering assembly lines.

Supermarkets are struggling to stock shelves amid chronic staff shortages. Airlines are grounding flights. Manufacturers are facing disruption and shipping lines remain backed up. At the same time, surging energy prices are adding to inflation, pressuring central banks to raise interest rates even as the recovery slows.

Optimists argue that the economic hit from omicron will be limited as vaccinations and boosters allow the disease to shift from an acute phase to an endemic one. U.S. Treasury Secretary Janet Yellen said she doesn’t expect the variant to derail the U.S. recovery.
