DS-2.1.18

The criticality of a function can be assessed in a three-step process: —

a) Impact assessment: It will include understanding the nature and extent of the activity and assessing the impact of the failure of the function on the market and infrastructure, on customers, on other market participants and finally the interdependencies of the market;
b) Evaluating the market for that function: This will encompass understanding how quickly the market is able to substitute the service providers of the failed function. Such an assessment will include supply side analysis of service providers covering market concentration;
c) Firm-specific test: The analysis will determine whether the bank's failure would have a material impact on third parties, on the potential for contagion and on the general confidence of market participants which will be based on understanding of the overall market share of the firm for that specific function etc.
