The review focused on groups acquiring financial advisers and wealth management firms.
It examined how these groups manage risks, debt, governance and integration during and after acquisitions.
The review found consolidation can support efficiency and sustainable growth. But, if not effectively managed, consolidation could lead to poor outcomes for consumers, employees and the wider financial system.
Good practice identified in the review included clear group structures, strong governance, effective monitoring of group debt and comprehensive risk management across all entities.
Firms that demonstrated well-planned acquisition strategies and thorough integration planning were also more likely to deliver positive outcomes for customers.
The review also highlighted areas with greater potential for harm. These included how groups were structured and how group debt was guaranteed.
In addition, the review highlights the importance of the effective management of group-wide risks and due diligence in the acquisition process.
We encourage firms to consider the findings of the review, assess their own arrangements and make any needed adjustments to their structures and processes.
