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.

The scope and depth of information-sharing practices among banks may significantly vary between financial markets, depending on the level of trust among participating banks.

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.
