Key figures
From Jan 2024 to Aug 2026 the index went from 212.2 to 230.9, a change of +8.8%.
Highest reading in that period: 253.4 in Feb 2025. Lowest: 212.2 in Jan 2024.
Largest one-month rise: +9.5% in Feb 2026. Largest one-month fall: -4.8% in Mar 2025.
For a clause that resets its base every year, a 10% cap or floor would have limited the adjustment in 2 of the last 20 months.

What this means for your clause
Used as a general escalator in agricultural supply and cooperative agreements that buy a mix of raw crops and livestock rather than one single material. Farm products are seasonal and weather driven, so a clause built on this aggregate benefits from a longer averaging window than a manufactured-goods clause would need.
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 — Farm Products (BLS series WPU01), 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.]
A food or agricultural escalation clause compares a current-period Producer Price Index value to the value at contract signing (the base period), turns that into a ratio, then applies the ratio to the contract price. BLS splits raw farm commodities (Farm Products, WPU01) from processed food inputs (Processed Foods and Feeds, WPU02); picking the wrong one indexes the contract to the wrong stage of the supply chain, and the series is unusually seasonal, which makes base-period selection especially important.
