Yes and no. It’s more that there is a lag time between demand and supply. So the scarcity is “manufactured” but simply because the manufacturer rolled the dice on the demand and lost.

Keep in mind, many manufacturers aren’t selling for more to stores when this happens, they typically have a contract setting a price.

Now, can the manufacturer back out of this contract and demand a higher price? It really depends on the contract wording. You can’t really be forced to sell things unless a specific number of items was part of the contract.
