Subcontracting

Also called sub-outsourcing, chain outsourcing

Definition

Subcontracting happens when a firm's service provider hands part of the service to another company. In financial regulation it is also called sub-outsourcing. Regulators expect firms to know which subcontractors support critical services, to set conditions on their use and to keep oversight of the whole chain.

How it works

The main contract sets whether the provider may subcontract, which parts of the service can be passed on and the conditions that apply. Providers notify the firm before adding or changing a material subcontractor, and the firm can object or exit. Due diligence, audit rights and data location terms flow down the chain. Firms record material subcontractors in their third-party inventory and, in the EU, in the DORA register of information.

Subcontracting matters because risk sits where the work is done. A failure at a data centre or software supplier two steps removed can stop a bank's payment service. Long chains also hide concentration, as many providers depend on the same few cloud platforms. Supervisors use subcontracting data to map these dependencies across the sector.

Common questions

What is the difference between subcontracting and fourth-party risk?

Subcontracting is the act of a provider passing work to another company. Fourth-party risk is the exposure that results. The subcontractor becomes the firm's fourth party, with no direct contract but a real effect on service delivery.

Do firms need to approve every subcontractor?

No. Rules focus on subcontractors that support critical or important functions. For these, contracts require notice of changes and give the firm a right to object or terminate. Lower-risk subcontracting is managed through general contract terms.

How does DORA treat subcontracting?

DORA requires contracts to state whether subcontracting of critical or important functions is allowed. Delegated Regulation (EU) 2025/532 adds detail on risk assessment, contract terms and monitoring. Firms also record relevant subcontractors in the register of information.
