We seem to be entering a global version of The Beer Game (https://en.m.wikipedia.org/wiki/Beer_distribution_game). The game is a training session on supply chain co-ordination designed to show effects of trying to order beer and bottles months ahead of time then demand changes etc. It's mostly chaos
(I was speaking to someone who has seen their shipping from China to Europe quintuple - apparently all the containers stayed in Europe as no one wanted to send them back empty.)
The game is designed to show that "local" signals aren't always indicative of full system - the example being that retailers etc are stockpiling right now on-shore. But this creates more demand than usual, slowing delivery. So the naive retailer will say "OMG it now takes 3 months and 2x price to get widgets, I had better order 4 months supply ... and so it goes - an infinite bug methodology.
