With this in mind, the PRA has drawn up guidelines to ensure financial institutions retain a degree of oversight over material outsourcing arrangements which involve or may involve sub-outsourcing. The guidelines are broadly similar to outsourcing guidelines the European Banking Authority (EBA) has previously issued as well as guidelines on outsourcing to cloud service providers more recently finalised by the European Insurance and Occupational Pension Authority (EIOPA). However, the PRA does include some general thoughts which may require financial institutions to revisit the approaches they are taking towards sub-outsourcing.
Due diligence and monitoring
According to the PRA, where a material outsourcing arrangement is likely to involve sub-outsourcing, the PRA "expects firms to assess relevant risks". Firms are expected to "pay particular attention to the potential impact of large, complex sub-outsourcing chains on their operational resilience and ability to oversee outsourcing arrangements".
Service providers can "facilitate firms' due diligence by maintaining up to date lists of their sub-outsourced service providers", the PRA said.
On oversight, the PRA's requirements more closely reflect the EIOPA cloud guidelines than they do the EBA's outsourcing guidance.
The EBA guidelines on outsourcing impose a requirement on financial institutions to take into account the extent to which the potential arrangement will affect their abilities to monitor all risks, but they do not directly state that financial institutions must monitor the sub-outsourced service providers. In contrast, EIOPA has said that firms should set up "monitoring and oversight mechanisms, which should take into account, where feasible and appropriate, the presence of sub-outsourcing of critical or important operational functions or a part thereof". The PRA's draft guidance is similarly worded.
The PRA has said: "While it may not be feasible for firms to monitor every service provider across the supply chain, firms should, at a minimum, monitor those sub-outsourced service providers involved in the provision of important business services, including their ability to stay within the firm's impact tolerances".
The PRA has further explained the conditions that firms must ensure have been met before they agree to sub-outsourcing. It said firms must ensure "the sub-outsourcing will not give rise to undue operational risk for the firm", as clarified in its guidelines. In addition, they must also ensure sub-outsourced service providers undertake to comply with all applicable laws, regulatory requirements and contractual obligations, and further grant equivalent contractual access, audit and information rights to those granted by the service provider.
A written agreement and contractual rights
Where sub-outsourcing is agreed to and concerns material outsourcing arrangements, the regulator said that firms should ensure this is documented in a written agreement between firms and the service provider. The agreement should set out any conditions to be complied with in the case of permissible sub-outsourcing.
The written agreement should further require that service providers obtain prior specific or general written authorisation from the firm before transferring data, in line with the requirements of article 28 of the General Data Protection Regulation, the PRA said.
