Ultimately, stress testing must be part of both the business planning process and the institution’s day-to-day risk management practice. Adjustments to asset-liability composition should align with management of concentration risk.
WebIn this chapter, we work with a flexible failure rate based SSALT model with pre-fixed but arbitrarily chosen failure rates at different stress levels. If s1 and s2 are the two stress levels and τis the stress changing time point, it is assumed that the hazard rate of the distribution under the step-stress pattern is as follows: h(t)=
