*Cost and price · Strong · Both ways*

Polyethylene and cross-linked polyethylene insulate most power cables, so grid build-out adds demand. The wire and cable price index moves with the resin proxy at 0.27 monthly and 0.68 yearly, also driven by copper.

- **0.27** monthly change correlation
- **0.68** 12-month change correlation
