Data & insights

Key figures

  • From Jan 2024 to Aug 2026 the index went from 620.2 to 580.5, a change of -6.4%.
  • Highest reading in that period: 620.2 in Jan 2024. Lowest: 514.7 in Dec 2024.
  • Largest one-month rise: +8.2% in Feb 2025. Largest one-month fall: -7.9% in Mar 2024.
  • For a clause that resets its base every year, a 10% cap or floor would have limited the adjustment in 4 of the last 20 months.

What this means for your clause

Scrap purchase agreements between steel mills and scrap dealers use this series directly rather than a finished product index, since scrap and finished steel prices can diverge sharply when scrap export demand or furnace utilization shifts.

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 — Iron and Steel Scrap (BLS series WPU1012), 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.]

How this index is used

How do you calculate a steel price escalation clause using the PPI?

A steel PPI escalation clause compares a current-period Producer Price Index value for a named steel series to the value at contract signing (the base period), turns that into a ratio, then applies the ratio to the contract price or affected line items. Clauses typically define the exact BLS series code, an averaging window, a publication lag, and a cap limiting the maximum adjustment.
