The notice establishes the principles and rules to be observed in advertising for financial products and services subject to the supervision of the Bank of Portugal, in advertising for activities, and in institutional advertising is at issue.

In this project, "the minimum font size for indoor posters intended for display outside the premises of supervised entities was adjusted to 40 points," according to the note published on the BdP website.

The goal is to "ensure that, even on smaller posters, there is a balance between the advertising message and the information that institutions are required to provide to bank customers so that they can, for example, compare different credit offers."

These rules include advertising for credit institutions, financial companies, payment institutions, and electronic money institutions, as well as credit intermediaries and other entities authorised to carry out credit intermediary activities.
