A credit institution shall have in place sound stress testing processes for use in the assessment of capital adequacy for CCR. These stress measures shall be compared with the measure of EPE and considered by the credit institution as Part of the process set out in Article 123. Stress testing shall also involve identifying possible events or future changes in economic conditions that could have unfavourable effects on a credit institution's credit exposures and an assessment of the credit institution's ability to withstand such changes.

The credit institution shall stress test its CCR exposures, including jointly stressing market and credit risk factors. Stress tests of CCR shall consider concentration risk (to a single counterparty or groups of counterparties), correlation risk across market and credit risk, and the risk that liquidating the counterparty's positions could move the market. Stress tests shall also consider the impact on the credit institution's own positions of such market moves and integrate that impact in its assessment of CCR.
