| Asset | Exposure and channel | Direction | Evidence |
|---|---|---|---|
| 2330.TW | Taiwan semiconductor production depends on broader electronics supply chains, but the quota’s direct impact on TSM is not established in the source | Watch1-4w | China set a quota to cap northern bastnasite extraction |
| REMX | tighter rare-earth supply can support rare-earth pricing and related miners | Up1-4w | the quota caps light rare earth mining output |
| SOXX | if input constraints ripple through electronics supply chains, chip hardware sentiment can weaken | Down1-4w | the tracker links the quota to supply restrictions on rare earth extraction |
