Potato Market Intelligence
Potato Weekly Average Price Replacement
A potato weekly average price replacement creates a new benchmark from explicitly eligible physical-market observations when an older series disappears. MassGain defines the basket, basis, weighting, exclusions, coverage, revisions, and overlap tests so the new reference is reproducible and its limits are clear.
Market Data
How to read this market
Potato weekly-average-price replacement data constructs a new weekly reference from explicitly eligible physical-market observations when an older series is unavailable. The market object is the defined price basket with product, grade, geography, delivery basis, transaction window, weighting, exclusions, publication timing, and revision policy recorded.
Use the data to build a reproducible average and report its sample size, volume coverage, range, concentration, and confidence. Run overlap or bridge tests before substituting the new reference in contracts or historical analysis.

Analysis
Why this matters
Two weekly averages can move differently even when the market is unchanged if their contributors, product mix, or freight basis differ. A replacement therefore needs methodological comparability, not just a similar headline level.
Commercial interpretation should use the replacement only to the degree its coverage supports. Thin or concentrated weeks may still be directionally useful while carrying less weight in settlement or negotiation.
Signal 01
Usable Crop Uncertainty Index
UCUI translates crop and market complexity into a simple uncertainty signal. Higher readings indicate greater uncertainty—not necessarily higher prices.
Understand uncertainty. Anticipate risk. Act earlier.
UCUI is designed to analyze potato-industry publications and data signals across regions, varieties, weather, disease, storage, supply, and demand.

Potato market steady for now; Russia’s smaller crop is the salient risk
Spot prices are flat and USDA terminal reports read ‘market steady,’ but a renewed forecast for a smaller Russian harvest and recent regional harvest stress leave seasonal import timing and storage losses as the key uncertainty.

Overview
Who is this for?
This page is for procurement and market-intelligence teams replacing a discontinued or unavailable potato weekly average price reference. MassGain rebuilds the benchmark from explicitly eligible physical-market evidence rather than copying a headline number from an incompatible source.
The framework defines product, grade, region, unit, delivery basis, transaction window, free-buy or contract status, weighting, exclusions, minimum coverage, publication timing, and revision policy. It can produce a matched weekly average, range, midpoint, sample size, concentration measure, and confidence label while preserving every underlying observation and transformation. Users can compare the new series with the former benchmark, identify structural breaks, and run parallel periods before using it in contracts or planning. Procurement can validate supplier escalators, finance can update cost models, and analysts can communicate when a replacement is directional rather than directly continuous.
The suite also supports company-specific purchase-mix weighting where the broad market basket is not representative. MassGain does not declare a universal official replacement or invent missing transactions. It provides a transparent methodology for creating a reproducible weekly price reference suited to the actual potato specification and decision.
Use Case
A buyer's contract references a weekly price series that is no longer published. MassGain reconstructs a matched regional free-buy average, runs it alongside the final year of the old series, and identifies a consistent freight-basis difference. The contract is amended using a documented bridge rather than a simple splice.
FAQs
What is needed to replace a weekly average price?
A defined market, eligible observations, normalization rules, weighting, coverage thresholds, and revision policy are needed.
Should the new series be spliced directly to the old one?
Only after overlap testing shows the definitions and behavior are sufficiently comparable.
How does MassGain show confidence?
It reports sample size, volume coverage, concentration, range, data gaps, and methodology alongside the average.
