Olive oil stocks: the number that anticipates price

Latest AICA figure: Spanish operators held 569,300 tonnes of olive oil as of 2026-07.

Prices tell you what the market thinks; stocks tell you why. Every month, Spain's food-chain agency AICA collects mandatory declarations from mills, refiners and bottlers — how much oil they hold, produce and ship out — and publishes the aggregate. For a market with one harvest a year and year-round consumption, that inventory number is the single best measure of how much cushion stands between today's demand and the next campaign.

Spanish stocks, last twelve reported months

Monthly aggregate stocks declared to AICA, in tonnes, as ingested by Olea Markets. Re-published months keep the freshest figure.

How to read the curve

Stocks follow a sawtooth: they peak at the end of the harvest (roughly February–March), then drain month by month until the new campaign starts in October. The absolute level matters less than two comparisons: the same month last year, and the pace of monthly outflows. Inventory falling faster than usual with months still to go before harvest is the classic early warning of a tight summer — often visible in the data well before it is visible in the price.

The enlace: the number that made 2023

The stock level on 30 September, when the Spanish campaign year closes, is called the enlace — the link between campaigns. It is the market's whole buffer against a bad harvest. The 2022–23 price explosion was, at its core, an enlace story: a short harvest arrived when the link was already thin, leaving no inventory to bridge the gap, and bulk EVOO went vertical. Conversely, a fat enlace mutes rallies even after mediocre harvests, because buyers can simply wait. Our 20-year price history shows how those episodes printed in the index.

Stocks and the Olea Price

The stocks series does not enter the Olea Price formula — the index is built purely from price observations, as documented in the methodology. We publish it as context, because the two series answer different questions: the index tells you where the market clears today; stocks tell you how much room it has to move. Analysts typically overlay them — price against year-on-year stock change — to judge whether a level is sustainable. For the fundamentals feeding both, start with how olive oil prices are set.
