2 Rating Methodology …  There are two dimensions on indicators:  Choice of indicator. Policymakers should have a wide range of indicators at their disposal, rather than relying on one single indicator, bearing in mind that each indicator has its own purpose  Indicator Thresholds. Policy tools could be based, at least in part, on certain values of indicators associated with those levels that signalled systemic stress in the past.  Threshold levels could be set at those values of the near-coincident indicators observed at the turning points identified in the past 2

3 Indicators & Benchmarks Source Rosenthal: www.newyorker.com/online/blogs/johncassidy/ -233.jpg 3

4 Identifying SHIELDS benchmarks  Determination of benchmarks is very important so that one knows how to interpret the results.  Benchmarks should be established up front.  The SHIELDS framework employs the following benchmarks: Absolute benchmarks, e.g. CAR; EU Surveillance Framework; Z-scores: Deviations from the mean normalised by the standard deviation Percentiles Signal Extraction Method 4

5 The Weighted CAMELS Framework 5

6 Quintile Scale  Relevant Range  A “relevant range” for each indicator is established based on low-to-high distribution of the data set for all countries. Outliers that lie outside 2SDev from the mean are excluded to avoid distortion.  Quintile Scale  As the scale is based on quintiles, the scoring between the best ("1") and worst ("5") are based on a sliding scale.  Consider the following example: Given (a) Lowest Return on Assets: -1.5 per cent; (b) Highest Return on Assets: 3.5 per cent; it follows therefore, (c) Relevant Range = 5.0. 6

7 Percentiles  Another possibility is to transform the variables in percentiles, using their sample cumulative distribution function – CDFs  In this case, the last percentile corresponds to a high instability period, while the value of the first percentile characterises a low stress level.  The other values around the median reflect an average risk level. 7

8 Identification of Historical Crisis Episodes  Lindgren, Garcia & Saal (1996) classify systematic banking crises on the basis of whether bank runs, portfolio shifts, bank collapses or large-scale government intervention.  Any other episodes of financial stability are classified as non-systematic crises.  Demirguc-Kunt and Detragiache (1998a) use a achievement of at least one out of four criteria: proportion of non-performing loans to total banking system assets exceeds 10%, or the public bailout cost exceeds 2% of GDP, or large scale bank nationalization, or extensive bank runs are visible and if not, emergency government intervention is visible. 8

9 Laeven & Valencia Data Set 2012  A banking crisis is defined as systemic if two conditions are met: Significant signs of financial distress in the banking system (as indicated by significant BK runs, losses in BK system (NPLs of 20%) & /or BK liquidations/ closures at least 20%. Significant banking policy intervention measures in response to significant losses in the BK system.  Consider the first year that both criteria are met to be the year when the crisis became systemic.  Policy interventions are significant if at least three out of the following six measures have been used: 1) extensive liquidity support (5 percent of deposits and liabilities to nonresidents) 9

10 Laeven & Valencia Data Set 2012 2) Gross bank restructuring gross costs (at least 3 percent of GDP). 3) significant bank nationalizations 4) significant guarantees put in place 5) significant asset purchases (at least 5% of GDP) 6) deposit freezes and/or bank holidays.  Liquidity support is extensive when the ratio of central bank claims on financial sector to deposits and foreign liabilities exceeds 5 % & more than doubles relative to its pre-crisis level.  Liquidity support extended directly by Treasury is also included. 10

11 Reinhart & Rogoff Crisis Definitions  Inflation crisis – 20% or higher, extreme 40%  Currency crush – Annual depreciation of 15% or more or currency debasement of 5% or removal of several “zeroes.”  Banking crisis – bank run leading to closure or merger or no runs but large scale closure/takeover  Debt Crisis- failure by government to honour  Domestic debt crisis – freezing deposits or forced conversions.  Global Financial Crisis ??? 11

12  Has global effect on the level and volatility of economic activity as measured by world aggregates of prices, real GDP, and trade; and Is relatively synchronised across countries  Has four main elements: One or more global financial centres are mired in a systemic crisis & also directlty or indirectly financial flows to numerous countries The crisis involves two or more regions The number of countries in each region is 3 or more Composite GDP weighted by index average of global financial is one std deviation above normal 12
