The return of empty shelves and panic buying

WALK around a supermarket in the US or Europe, and you will see some empty shelves once more. This isn't due to people panic-buying toilet paper, as they did early on in the pandemic; rather it's because supply chains are clogged at almost every stage between Asian factories and grocery stock rooms.

But rising prices and patchy availability mean it's only a matter of time before shoppers start purchasing in bulk again - this time to avoid future sticker shock.

Supply lines are struggling as producers such as Vietnam, responsible for making everything from sneakers to coffee, are hurt by Covid restrictions. Surging virus cases and consumer demand are leading to congested ports. Shipping containers are in the wrong place. Sea freight costs are up tenfold. If goods do arrive at the destined ports, there are too few truck drivers to transport them to retailers. Shortages of workers to harvest and prepare foods are also adding to the pressures.
