This article gives lots of measures of factors contributing to supply chain cost. There are good graphs indicating the changes.
But these are contributing hidden costs to products, and those costs will be borne by consumers of the final products. That’s inflation.
It may be the first time that inflation is influenced by marine supply chain problems since the incessant wars on the seas in the 17th and 18th century. And in those days, frequent shooting wars guaranteed recessions; it was leisure goods like tea that had inflated prices. World Wars I and II also caused inflation, and shortages, but these were only partly caused by pillaging of marine traffic on the high seas. In most cases price controls were put into effect to resist inflation for ordinary people; and the extra goods were needed for the soldiers. We don’t have those now.
Somehow in the US and EU we need to find people to do the hard jobs in the supply chain to keep goods moving— warehouse jobs and driving jobs.
