A book called Chip War by Chris Miller gives some idea of the mayhem that would break loose in the event of an invasion of Taiwan and the west's subsequent lack of access to the cutting edge microcuircits that currently are only made there. Miller asserts that loss of this production would be as big of a hit to the world economy as the 1979 Oil crisis.
Interestingly though, the technical support supply chain is such that were Taiwan to fall under Chinese control Taiwanese chip production could only continue if the west, mainly Europe, continued support for the production hardware that the Taiwanese companies are using.
