Strongest average month-over-month move historically: May (+4.4% avg).
Electrical contractors and cable suppliers escalate wire and cable line items against this series rather than a raw copper index, since drawing, insulating, and jacketing add labor and material cost that raw copper price alone does not capture.
A starting point citing this series by name and code. Replace the bracketed terms with your contract's actual scope before use.
The [affected portion] of the Contract Price shall be adjusted using US PPI — Copper Wire and Cable (BLS series WPU10260314), published by BLS. Base Period: the index value published for August 2026 (or the month of contract signing, if different) is the Base Value. Adjustment: at each Adjustment Date, the Current Value is the most recently published three-month average of the index (the Averaging Window). The Escalation Factor equals Current Value divided by Base Value. Cap: the Escalation Factor applied under this clause shall not exceed 1.10 or fall below 0.90 (a 10% cap and floor) in any single Adjustment Date, regardless of the index's actual movement. [Replace bracketed terms with your contract's actual affected-portion definition and adjustment-date schedule before use. This is a drafting starting point, not legal advice.]
