It's all based on projections from upstream supplier commitments as well as prior customer commitments so very much subject to change in either direction. I looked and couldn't find a name for it but there's an accordion effect that flows through supply chains after a big disruption. This is just part of it. The problem is that it's not an acyclic graph, e.g. chip suppliers need robots too, so it can take a long time to shake out of the system.

> I looked and couldn't find a name for it The bullwhip effect[1]. Although in this instance, it's inverted from its traditional direction. Generally the closer you are to the consumer/end product in the supply chain, the less impacted you are by the bullwhip effect. Tiny deviances between your actual and forecasted/expected demand can result in reactionary changes to materials orders, which grow in magnitude and volatility as you follow the downstream supplier chain. So the whip goes from those closest to the consumer upstream to those further away. Car companies canceling chip orders at the beginning of the pandemic are an example of what's generally considered the bullwhip effect. Suppliers generally have little choice but to put up with the volatility, because if they don't they risk their customer sourcing a different supplier that _will_ and losing the account entirely. That said, the power dynamics now are different. Many suppliers have more demand than their ability to service it right now, either because of constrained materials supplies themselves, lack of manpower, or lack of additional capacity. And those capacity constraints are hitting suppliers industry wide, so the "upstream" consumers of those materials have no alternatives to source. Hence why the bullwhip is going in reverse from how it typically does, where the ones closest to the end product are the ones at the mercy of the suppliers they source materials from.
