User guide
Policy background. In a crisis authorities will be confronted with two basic questions: whether to intervene, and if so how to intervene (e.g. through facilitating a private sector solution, public statements, liquidity support and recapitalisation). As a rule, the handling of a crisis and its resolution are primarily the responsibility of the institution(s) involved. Public intervention, in particular when public money is at risk, should only occur when there is a clear systemic risk, i.e. when there is a serious disturbance of the financial system that, as a result, may have a major impact on the real economy. The purpose of the template is to provide a common language to authorities when they discuss such systemic assessments and the possible effects of related policy measures in a cross-border context. In this way, it enables them to address more clearly any differences in their views on the impact of the crisis and reduces the risk that under the pressure of circumstances they might start discussing how to resolve a crisis before assessing its potential impact. A formal assessment, backed-up by supporting material, further enhances the authorities’ accountability for any recommendations made.
Scope assessment. The assessment should be made from the perspective of the domestic financial system, composed of financial institutions, markets and infrastructure, and the domestic real economy. The domestic financial system needs to be defined with reference to those parts that have the potential to disturb the domestic real economy. In defining the financial system’s three components, one should be wary of possible overlaps (resulting in double counting) and gaps. The real economy assessment should include and only include the effects of the crisis intermediated via the domestic financial system and via foreign financial systems (e.g. direct lending from abroad). In principle, all foreseeable effects should be taken into account, although the further away in time the effects are, the greater the uncertainty. Hence, it might be useful to differentiate between short-term and long-term effects.
Prioritisation in the assessment. In the case of a rapidly unfolding crisis, one may need to focus the assessment on the most critical parts of the financial system. These are likely to be the (major) banks, the markets they use for their daily funding and active balance sheet management, and the related infrastructure (e.g. large value payment systems). In such a situation, one may also need to place more reliance on qualitative judgements rather than on up-to-date quantitative information.
Factors influencing the assessment. The assessment of the financial system’s components should reflect
the critical nature of their affected parts and their extent of disturbance. For both factors, a number of possible indicators can be used. The extent of disturbance will be influenced by the presence of risk mitigants. Two main criteria are relevant for a part’s critical nature:
Systemic impact score. The score is a decimal number that reflects the assessment of the impact of the crisis on the components of the financial system and the real economy relative to four base cases: 0 (no impact),1 (limited impact), 2 (serious impact), 3 (very severe impact).
The score should take into account both the state of the financial system and the real economy before the crisis and the additional impact of the crisis. For example, when the financial system is already in a weak shape, the effect of a crisis is likely to be bigger (higher score) than if the financial system is robust (lower score). The score should be supported as much as possible by quantitative information. The four separate scores are graphically represented in a “heat map”. The heat map is a snapshot in time and one may need to construct a series of maps over the life of a crisis. Moreover, an initial assessment that is relatively benign can quickly change if vulnerabilities are present in the financial system or the real economy. Authorities should therefore be careful not to overlook elements that are not fully captured by the map.
Range of the score. The score is a reflection of an assessment which involves a significant degree of uncertainty and discretion. A range can be defined for each score reflecting the uncertainty relating to the assessment, with the lower boundary corresponding to a “best case” scenario and the upper boundary to a “worst case” scenario. Authorities may try to attach a qualitative likelihood (e.g. “most likely”, “very unlikely”) to the scenarios. Given the large potential costs associated with a systemic financial crisis, authorities should pay particular attention to the worst case scenario.
Contagion channels. These are the real/exposure-based or information-based channels through which shocks can be transmitted between various parts of the financial system. They should be explicitly considered in the assessment, in particular their cross-border dimension, as they are often crucial in times of crisis. The following table might be helpful in identifying the main channels.
