Key figures
From Jan 2024 to Aug 2026 the index went from 433.2 to 469.3, a change of +8.3%.
Highest reading in that period: 469.3 in Aug 2026. Lowest: 314.6 in Jan 2025.
Largest one-month rise: +10.9% in Mar 2025. Largest one-month fall: -12.6% in Mar 2024.
For a clause that resets its base every year, a 10% cap or floor would have limited the adjustment in 12 of the last 20 months.

What this means for your clause
Automotive and appliance stamping supply agreements typically name this series rather than the broader steel mill products index, because cold rolled sheet carries a separate finishing premium over hot rolled that a blended index would understate.
Draft a clause
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 — Cold Rolled Steel Sheet and Strip (BLS series WPU101707), 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.]
Compare the current value of BLS series WPU101707 (Cold Rolled Steel Sheet and Strip) to its value at contract signing, turn that into a ratio, and apply the ratio to the cold rolled steel sheet-affected line items. A usable clause also names an averaging window, a publication-lag rule, and a cap.
Escalake tracks US PPI — Cold Rolled Steel Sheet and Strip, applies your formula, and gives both sides a number they can confirm, no spreadsheet required.
