Each bank director is required to sign their bank's disclosure statement and to certify that disclosures made are not false or misleading. If a disclosure statement is found to be false or misleading, directors are subject to potentially severe legal penalties, including substantial fines and imprisonment.
Among other benefits, I believe that these events shorten the distance between citizens and central banks, enabling the public at large to become familiar with our institutions and showing our generally “austere” class of central bankers in a different light. This was one more reason why Banca d’Italia was glad to embark on this “adventure”.
