The Australian Prudential Regulation Authority issued Prudential Standard APS 222 to require authorised deposit-taking institutions to manage contagion and step-in risks arising from their associations with related entities. The standard mandates that institutions maintain Board-approved policies, implement robust risk management systems, and adhere to strict limits on exposures to prevent financial instability. It further regulates the provision of support, group badging practices, and participation in group operations to ensure transparency and safeguard the safety and soundness of the institution.
