Banks must conduct stress tests based on sufficiently severe, but plausible scenarios and assumptions that are commensurate with the bank's business nature, size and complexity. The stress testing scenarios and assumptions adopted by a bank must reflect the current market conditions and address the bank's actual experiences in stressed situations. Such scenarios and assumptions must be reviewed regularly by the senior management, with any major changes endorsed by the bank's Board or its relevant delegated committee(s). The active involvement of senior management is vital to the stress testing process. During their regular reviews, senior management must consistently require consideration of sufficiently severe stress scenarios.
