Taiwan (Republic of China) → TSMC and the semiconductor ecosystem

The parties

• Taiwan (Republic of China) economically dependent on TSMC and the semiconductor ecosystem
• TSMC and the semiconductor ecosystem economic dependency of Taiwan (Republic of China)

A directional arrangement: the two parties do not hold the same position in it. Authored once and read from both ends.

Active

In force and operating. Says nothing about how well it is working, or about which way it is heading.

What the arrangement covers

Categories the arrangement is documented to include. Not a measure: a relationship covering more of them is described in more detail, not held more firmly.

Summary

The semiconductor ecosystem centred on TSMC produces the majority of the world's most advanced logic chips, and it is central to Taiwan's economy, its tax base and its international standing. The dependence runs in one direction in the sense that matters here: the industry could in principle be reconstituted elsewhere over a decade, and the state's fiscal and diplomatic position could not be reconstituted without it. That is also why the relationship is being actively changed from outside — substantial capacity has been committed to Arizona, the United States, Japan and the European Union are all courting fabrication investment, and American export-control policy regulates in effect what the industry may sell and to whom. Chinese customers account for a modest share of revenue under periodically renegotiated licences.

Why it matters

It is why this module has an economy section at all, and why its security questions are read in capitals with no view on Taiwanese politics. It is also the source of the module's most contested proposition — whether concentration deters attack or invites it — which this record does not attempt to settle.

Systems it depends on

Canonical logistics records. They carry the corridors, nodes, dependence and disruption history that this relationship rests on and does not restate.

What remains unknown

• This module does not record the date the dependence became structural. `validFrom` is given as 1987, the standard founding date for the company at the centre of the ecosystem, and is context rather than a claim these sources establish.
• Vigil publishes no revenue shares, tax contributions, employment figures or output volumes. The dependence is recorded as structural rather than measured.
• Whether overseas capacity expansion materially reduces the concentration, and on what timescale, is not established and is contested.

Readings the evidence also supports

• The concentration is read by some as a deterrent — an asset too valuable to the world economy to be destroyed or seized intact — and by others as an incentive and a vulnerability. This module records the concentration as a fact and treats its deterrent effect as unresolved.

Listed because the record's own assessment is not the only one its sources permit — not as a hedge on the assessment above.
