Food commodity prices inside AI assistants

On 30 September, one of the price reporting agencies that publish benchmark prices for food commodities, olive oil among them, connected its data to AI assistants. A buyer or trader with a subscription can ask in plain language for a benchmark, its recent history, a forecast or the latest market commentary, and read the answer inside the assistant already open on the desk instead of searching a separate price platform.

The connection uses the Model Context Protocol (MCP), an open standard for linking AI assistants to the systems where data lives, which since December 2025 has been governed by a foundation under the Linux Foundation. An agent, in this context, is an assistant allowed to take steps by itself, for example pulling twelve weeks of a benchmark, setting it against a supplier's offer and drafting a note for the buyer.

Who gains access to price data through an assistant

For an importer or a food manufacturer, the agency presents the connection as a way to prepare negotiations, speed up sourcing decisions and forecast costs, and it already runs an agent that builds cost models, breaking a product's cost down into its inputs. A buyer of olive oil for sauces or ready meals can ask for the benchmark, its trend and the agency's commentary in the same question, then compare the result with the offers on the table.

Olive oil benchmarks are published by origin and grade, so a trader or broker can follow several origins in one query. One agency's weekly extra virgin indices, one conventional and one organic, combine Spanish, Italian and Greek series weighted at 70.98%, 15.81% and 13.21%.

Commercial benchmarks are sold by subscription. A free reference for producers and cooperatives is the European Commission's weekly olive oil prices, which cover more than 20 markets in the main producing member states, with some series going back to June 2010, and can be read by software through an interface (API). Its olive oil dashboard shows national averages for Spain, Italy and Greece by grade, with sources that include member states' declarations.

Bulk commodities are priced long before they reach a bottle or a shelf, and the same product can carry several prices at once.

Four kinds of price can answer the same question

A benchmark from a price reporting agency is an assessment of where the market stands. Spain's transaction-price system for bulk olive oil, run by a sector foundation, records completed sales between producers and marketing companies and publishes averages weighted by volume and dated by the day of payment, for subscribers. The Commission's weekly figure is a national average compiled from sources that include member states' declarations. A seller's offer is what one company asks for one lot, before any buyer has agreed to it.

Each of the four is built from different inputs over a different period, so on a given day they need not match. An agent asked for "the price of Spanish extra virgin today" can return any of them, and the answer is only as useful as the label that comes with it.

An assessed price comes from a market survey

One agency's assessment methodology shows how a benchmark is reached. In each period its reporters survey buyers, sellers, traders and brokers, check each price input against other sources, discount anomalous data and convert non-standard terms to the standard specification. Concluded transactions and competitive, open bids and offers take precedence over indicative prices, and where market data are thin the reporter applies editorial judgement based on spreads, related products, freight costs or changes in supply and demand. Some assessments are fixed at a cut-off time, such as the olive oil indices above, which reflect "the transactable value at 16:00 London time", while others cover the whole assessment period.

That order of inputs follows the IOSCO Principles for Oil Price Reporting Agencies of October 2012, which rank concluded transactions first, bids and offers second and other market information third, and ask agencies to explain how much judgement went into each assessment. The principles were written for oil, and IOSCO encouraged agencies to apply them to any commodity derivatives contract that references their prices.

Published prices are sometimes corrected

In October 2025, one agency corrected its olive oil benchmark for Andalusia for two weekly assessments, revising "the assessed price points and rationales". The agency's methodology commits to publishing such notices, and it does not reissue an assessment because of information that arrived after publication. A figure an agent pulled before a correction stays in every spreadsheet or chat history it was copied into, until someone checks the notices.

The person using the answer still checks it

One agency states on its product page that its AI tool "can hallucinate or make mistakes", meaning it can give an answer its data do not support, and that "users are responsible for checking that the outputs … are correct". The approval step therefore stays with the buyer or the seller, and the price that goes into a contract or a negotiation brief is the one a person has checked against the source.

Prices and freight now reach the same assistant

Paid benchmarks now also reach AI assistants, the Commission's weekly averages can be read by software through its API, and the Spanish transaction averages stay behind a subscription. Freight quotes and bookings moved into the same assistants at the end of September, so a buyer who holds both subscriptions can compare a supplier's offer, a benchmark and a freight rate in one conversation. A producer who checks the same offer against the Commission's weekly national average is looking at a different kind of figure, built from different inputs.

Five questions to ask of any price an agent returns

Price type: an assessment, an average of completed sales, a public national average or a single offer.
Date and cut-off: the day of the price and, where it applies, the time of day it reflects.
Delivery terms: an ex works price and a CIF price for olive oil include different costs, and the location changes the figure again.
Grade: extra virgin, virgin or lampante, conventional or organic.
Corrections and licence: whether the figure was corrected after publication, and whether the subscription covers access through an AI assistant.
