Archived resource – H2 2015 stress scenario (for information)

​Update 30 March 2016 – The content on this webpage is for information only. Please visit the Stress test scenario webpage for the latest information.

 
For firms to which CRD IV applies, rules and expectations in relation to stress testing, scenario analysis and capital planning can be found in the PRA Rulebook in Chapter 12 of the Internal Capital Adequacy Assessment rules and in SS31/15. For other firms, including insurers, relevant rules and additional guidance on stress testing and capital planning can be found in the PRA Handbook in GENPRU 1.2, BIPRU 2.2 and INSPRU 7.1. In line with SS31/15 and GENPRU 1.2.73B within the PRA Handbook, the Prudential Regulation Authority (PRA) publishes a macroeconomic scenario for the United Kingdom which firms may use as a complement to their own scenarios. The scenario should be used by firms as a guide to calibrate their own scenarios for Pillar 2 capital planning stress tests. Note that the scenario is for stress testing purposes only, and the scenario paths should not be interpreted as a forecast of the macroeconomic outlook for the United Kingdom or elsewhere.

The scenario is separate from the concurrent stress testing that is being undertaken by the Bank of England in response to recommendation six of the Financial Policy Committee’s meeting on 19 March 2013.
Background to supervisory scenarios
As part of PRA efforts to strengthen firms' Pillar 2 stress testing, the PRA believes that supervisory scenarios will help firms to undertake stress tests using more appropriate scenarios, and will give firms a clearer indication of our expectations of appropriate severity. In addition, the scenarios are designed to encourage:
·         engagement of senior management: firms' awareness of the reputational considerations associated with undertaking stress testing exercises using recommended scenarios should result in senior management being better engaged in the stress testing process;
·         overcoming 'disaster myopia': during prolonged periods of economic stability, firms tend to underestimate the probability of adverse outcomes and the potential crystallisation of 'tail risks’. One way of addressing this is for supervisors to portray scenarios that represent a 'tail event' allowing firms to set their own stresses accordingly; and
·         benchmarking of results and approaches: asking firms to run scenarios that are broadly comparable in terms of severity will allow supervisors to more easily compare and benchmark individual results and firms' approaches to stress testing.
 
How the H2 2015 stress scenario should be used
Firms should consider both the H2 2015 stress scenario and concurrent scenario in the context of their business and specific risk drivers. These scenarios should be used as a starting point with which to build and calibrate their own scenario under Pillar 2. These scenarios reflect minimum adverse conditions, through which firms should assess their ability to maintain minimum specified capital levels.
Roll-forward methodology
The H2 2015 stress scenario is a mechanical update of the H1 2015 stress scenario. It seeks to incorporate developments in the macroeconomy over the first half of 2015 and has been produced in a mechanical way, with a view to achieving broadly the same level of severity. Consideration was given to two approaches in determining the severity of the updated scenario relative to the H1 2015 stress scenario, taking into account data outturns for H1 2015. These were the severity implied by maintaining the peak or trough levels reached by key variables in the H1 2015 stress scenario, and by applying the same quarter-on-quarter changes as those specified in the H1 2015 stress scenario. Equal weight was attached to each of these approaches in producing the mechanical update. The key variable paths can be found in Archived resources below.
The scenario is founded on the same economic narrative as the H1 2015 stress scenario (see Archived resources below). The PRA is aware of the challenges of developing a macroeconomic scenario that is to be used by various firms operating under different business models and exposed to a variety of risks. Therefore, the scenario is intended to help firms calibrate the severity of their own capital planning stress scenarios under Pillar 2, and should not undermine firms’ efforts and responsibility to develop their own scenarios.
Specific points for consideration by insurers
The H2 2015 stress scenario aims to give firms a consistent basis on which to confirm that their planned capital resources are sufficient to remain solvent and adequately capitalised in order to continue to write business throughout the capital-planning horizon (normally three to five years).
Firms should consider the conditions implied by the parameters set out in the H2 2015 stress scenario in order to derive consistent assumptions, on a prudent basis, for key risk factors that would affect their projected capital requirements. Firms should also consider insurance risk aspects (eg recession-related claims) arising from the scenario.
Insurers should incorporate these assumptions into their capital planning processes, and be prepared to show this in discussions with their supervisors. Insurers should also examine the complementary relationship between the one-in-200-year required stress for the Pillar 2 Individual Capital Assessment (ICA) and the macroeconomic scenario used for capital planning purposes. For example, a four-year capital plan might assess how a firm expects to be able to continue to meet its capital requirements (including ICA) over the next few years in the face of a changing economic environment.
The next update of the stress scenario in H1 2016 will take into account a Solvency II environment.
