The sharing of cybersecurity information among banks is less frequently observed and generally considered to be less effective than other cyber-security information-sharing practices.

Sharing of information and collaboration among banks depends on the financial industry's culture and level of trust among participants.

Information-sharing among different national regulators has evolved significantly over the past several years and is now a widespread practice at a large majority of jurisdictions.

Existing peer-sharing mechanisms among banks focus on the exchange of information related to cyber-security incidents, but such information is generally not shared from banks to regulators.
