The ongoing transformation from traditional banking to highly digitalized operations using automation and alternative intelligence has failed to reduce financial and non-financial risks. Banks operating in the financial technology or neo-bank (fintech) space are creating similar risks such as excessive debt, inadequate governance or financial crime.

It revisits the SSM’s classification test as well as take-over option and proposes a flexible, risk-based approach.
