Every month, the Observatory publishes a four-page analysis note, focused on the index, the major sales and a topical subject. The notes are free and published in the three languages.

They serve to follow the market without waiting for the annual report. They are written by the Observatory's analysts and reviewed by management before publication.

Typical content of a note.

The content of a note

The note opens with the month's index, with its change, its highlights and the comparison with the same month of the previous year. It then presents the major sales, their prices and their lessons. A box covers a topical subject: a regulatory measure, a restitution, a change in a segment.

Each note ends with a five-line "Key takeaways" section and a list of the data used, with a link to the open databases.

A few subjects covered in 2024

The 2024 notes dealt with the effect of certificates on prices, the behaviour of buyers in Asia-Pacific, the role of price guarantees in major sales, the first data on approved platforms and the change in unsold rates.

Each comes with reusable charts and a support sheet for teachers and trainers. The most read notes are those that analyse a concrete phenomenon, with examples and figures.

Notes and public decisions

Several administrations of Member States use the analysis notes to inform their decisions: calibrating a tax, setting priorities for a support plan, adjusting an export regime. The notes are designed to remain accessible to non-specialists.

The Observatory also prepares, at the request of States, tailor-made thematic notes, which are then made public after a six-month period.
