On 1 July 2015, the PRA updated the stress testing section of its webpage to report that it has requested the UK's largest general insurers to participate in a stress test exercise. The stress tests are developed to inform the PRA's work in assessing the resilience of UK insurers and in monitoring how insurers are developing their own risk and solvency assessment. The PRA has also published a spreadsheet for the stress scenarios and accompanying notes.  Participants have until 1 October 2015 to respond.
