Husfarm Persimmon Index

Constituents

An index includes every wholesale-level Husfarm quotation of its product, type or category that is dated within 31 days of the publication date: prices at wholesale markets, from wholesalers and at produce and fish auctions, and wholesale prices from official price reports. Farm-gate and purchase prices, selling prices of processors and packers, retail prices, exchange quotations, international benchmarks and prices from reports that do not state the stage of the supply chain are left out, so every index compares prices at the same stage. Futures, processed, dried, frozen and cooked forms are left out, as are by-products such as bran or offal. A product index covering the world needs at least 20 quotations from three countries; a continental index needs 15 quotations from four markets in two countries.

Median price

The headline price is the median of the constituents in EUR per kilogram. Prices are converted at the exchange rates of 10 November 2026 and quotations without a known weight per unit are left out of the median. The median is not moved by one extreme market, and the interquartile range on each index page shows how wide prices are.

Latest change

The latest change compares each constituent with its own previous quotation (at most 21 days earlier), in the same currency and unit. Changes are averaged geometrically within each market and then across markets, so each market counts once and exchange-rate moves do not affect the figure. It needs at least two markets.

Monthly index

For each series Husfarm takes the average price of the month, converted to EUR at that month’s average reference rate of the European Central Bank. The month-to-month change of every series quoted in both months (or in the month and up to two months before) is averaged geometrically within its market, then across markets with equal weights, and the monthly links are chained. Changes beyond a factor of four are treated as unit or data errors and dropped. Composite indices chain the equally weighted links of their product indices.

A month is published only when at least three series from two markets (four product indices for a composite) are available, and the history starts after the last month that does not meet this condition. A history of fewer than six months is not shown. The reference base is the 2025 average = 100 where the history covers the whole of 2025, otherwise its first month. The last published month is October 2026; ECB reference rates are used up to 10 November 2026.

Series quoted in currencies without an ECB reference rate or a fixed peg to one (for example the Uruguayan and Argentine peso) count in the median price and the latest change but not in the monthly index.

Revisions

Indices are recalculated with every update of the quotations. Late or corrected quotations can revise the latest months; the full series is always available as CSV.
