Stress testing is still an enormous challenge for even the largest banks.
A majority of banks across all asset sizes finds that stress testing is still a difficult and labor intensive exercise with significant room for improvement in both the processes and systems used. From pulling and cleaning data on the front end to aggregating the results and populating the templates, the processes and systems in place are inefficient, iterative, and lack integration and flexibility. Along with regulatory compliance, improving the efficiency of the bank’s stress testing program is a top goal. Most banks approached their inaugural stress testing exercise looking to limit their direct costs until they understood the reaction they would receive from regulators. What they discovered is that there are large direct and indirect costs associated with inefficient stress testing processes and systems. Banks that must spend significant resources just to complete regulatory stress tests frequently do not have the capacity to incorporate the stress testing results into their risk management activities and even less resources available to perform additional stress testing and scenario analysis based on their unique risk characteristics. If these banks are able to improve the efficiency of their stress testing, they will also be able to improve their risk management capabilities.
The lack of a coherent, integrated data system poses a major challenge.
Efficient data management at banks can prove to be daunting. A majority of banks’ data management systems are works in progress. Data pulls and cleanup on the front end are significant sources of inefficiency. While the importance of a smart, coherent data management strategy cannot be overstated, solving the data problem alone will not address a majority of the key issues causing problems for banks in their stress testing programs. Difficult activities such as aggregation, reconciliation and process consistency are a challenge because of the system architecture used to complete the stress test. Many banks have made extensive use of proprietary systems when stress testing requirements became a reality. While it was natural to leverage current systems as much as possible for the stress testing exercise, many of these older systems were not up to the task, causing as many challenges as they solve.
Centralized planning and management of stress testing can help efficiency.
Banks have taken a variety of approaches to managing their overall stress testing efforts. While banks find the process to be labor intensive and inefficient with much room for improvement, those that utilize a centralized approach to planning all stress testing activities in partnership with experts in CCAR find their processes to be most effective and efficient.
