After the COVID crisis, catch-up in demand for industrial products but not for services, hence the temporary imbalances
In the wake of the COVID crisis, demand for industrial products has been very vigorous, as the fall in demand during the crisis has been recouped; demand for services is less strong, as it is more difficult to catch up on the unrealised consumption of services. This is resulting in a temporary shift in the structure of demand towards industrial products, hence the increases in commodity prices and the bottlenecks observed. But because this configuration results from catch-up, it is likely to be temporary, just like the inflation it is giving rise to.
