On 19 January 2023, the Association Française de la Gestion financière (AFG) published the spread table for December 2022. „Published half-spreads are calculated over a 12-month rolling period.

The indicated spreads may be used for purposes of MiFID II and PRIIPS transaction cost calculations (if arrival prices aren’t available).
