Data & insights

Key figures

  • From Jan 2024 to Aug 2026 the index went from 297.5 to 386.4, a change of +29.9%.
  • Highest reading in that period: 389.0 in Jun 2026. Lowest: 289.0 in Jul 2024.
  • Largest one-month rise: +8.3% in Apr 2026. Largest one-month fall: -9.2% in Dec 2025.
  • For a clause that resets its base every year, a 10% cap or floor would have limited the adjustment in 10 of the last 20 months.

What this means for your clause

Sometimes used in older fertilizer supply contracts drafted before the more granular phosphate fertilizer materials series existed, since this one has a longer continuous history back to 1982. A new contract drafted today should generally prefer the more granular series unless a long historical baseline is the deciding factor.

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 — Phosphates (BLS series WPU065202), 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.]
