Linear Probability Models (LPMs) * Econometric model to explain repayment experience on past/old loans. * Regression model with a “dummy” dependent variable Z; Z = 1 default and Z=0 no default. * Weakness: no guarantee that the estimated default probabilities will always lie between 0 and 1 (theoretical flaw) Logit and Probit Models * Developed to overcome weakness of LPM. * Explicitly restrict the estimated range of default probabilities to lie between 0 and 1. * Logit: assumes probability of default to be logistically distributed. Probit: assumes probability of default has a cumulative normal distribution function.

Linear Discriminant Analysis * Derived from statistical technique called multivariate analysis. * Divides borrowers into high or low default risk classes. * Altman’s LDM = most famous model developed in the late 1960s. Z < 1. 8 (critical value), there is a high chance of default. * Weaknesses * Only considers two extreme cases (default/no default). * Weights need not be stationary over time. 3. New Credit Risk Evaluation Models Newer models have been developed – use financial theory and financial market data to make inferences about default probabilities.

* Most relevant for evaluating loans to larger corporate borrowers. * Area of very active continuing research by FIs. Credit Ratings * Ratings change relatively infrequently – objective of ratings stability. * Only chance when there is reason to believe that a long-term change in the company’s creditworthiness has taken place. * S&P: AAA, AA, A, BBB, BB, B and CCC * Moody’s: Aaa, Aa, A, Baa, Ba, B and Caa Bonds with ratings of BBB and above are considered to be “investment grade” Estimating Default Probabilities 1. Historical Data * Provided by rating agencies e. g. cumulative average default rates * If a company starts with a: * Good credit rating, default probabilities tend to increase with time. * Poor credit rating, default probabilities tend to decrease with time. * Default Intensity vs Unconditional Default Probability * Default intensity or hazard rate is the probability of default conditional on no earlier default. * Unconditional default probability is the probability of default as seen at time zero. Default intensities and unconditional default probabilities for a Caa rated company in the third year

Supplement point 14 by monitoring a combination of internal reports, prudential reports and market information. 16. Should intervene to require effective and timely remedial action to address liquidity deficiencies. 17. Should communicate with other regulators e. g. central banks – cooperation TOPIC 7: CORE PRINCIPLES OF EFFECTIVE BANKING SUPERVISION Overview * Most important global standard for prudential regulation and supervision. * Endorsed by vast majority of countries. * Provides benchmark against which supervisory regimes can be assessed. * 1995: Mexican and Barings Crises Lyon Summit in 1996 for G7 Leaders. 1997: Document drafted and endorsed at G7 meeting. Final version presented at annual meetings of World Bank and IMF in Hong Kong. * 1998: G-22 endorsed * 2006: Revision of the Core Principles * 2011: Basel Committee mandates a major review, issues revised consultative paper. The Core Principles (2006) * 25 minimum requirements that need to be met for an effective regulatory system. * May need to be supplemented by other measures. * Seven major groups * Framework for supervisory authority – Principle 1 * Licensing and structure – Principles 2-5 * Prudential regulations and requirements – Principles 6-18 *

Methods of ongoing banking supervision – Principles 19-21 * Accounting and disclosure – Principle 22 * Corrective and remedial powers of supervisors – Principle 23 * Consolidated and cross-border banking – Principles 24-25. * Explicitly recognise: * Effective banking supervision is essential for a strong economic environment. * Supervision seeks to ensure banks operate in a safe and sound manner and hold sufficient capital and reserves. * Strong and effective supervision is a public good and critical to financial stability. * While cost of supervision is high, the cost of poor supervision is even higher. Key objective of banking supervision: * Maintain stability and confidence in the financial system * Encourage good corporate governance and enhance market transparency Revised Core Principles (2011) * Core Principles and assessment methodology merged into a single document. * Number of core principles increased to 29. * Takes account of several key trends and developments: * Need to deal with systemically important banks * Macroprudential focus (system-wide) and systemic risk * Effective crisis management, recovery and resolution measures. Sound corporate governance * Greater public disclosure and transparency enhance market discipline. * Two broad groups: 1. Supervisory powers, responsibilities and functions. Focus on effective risk-based supervision, and the need for early intervention and timely supervisory actions. Principles 1-13. 2. Prudential regulations and requirements. Cover supervisory expectations of banks, emphasising the importance of good corporate governance and risk management, as well as compliance with supervisory standards.

An appropriate level of systemic protection (or public safety net) 6. Effective market discipline 001: IMF and World Bank Study on Countries’ Compliance with Core Principles * 32 countries are compliant with 10 or few BCPs * Only 5 countries were assessed as fully compliant with 25 or more of the BCPs. * Developing countries less compliant than advanced economies. * Advanced economies generally possess more robust internal frameworks as defined by the ‘preconditions’ 2008: IMF Study on BCP Compliance * Based on 136 compliance assessments. * Continued work needed on strengthening banking supervision in many jurisdictions, particularly in the area of risk management. More than 40% of countries did not comply with the essential criteria of principles dealing with risk management, consolidated supervision and the abuse of financial services. * More than 30% did not possess the necessary operational independence to perform effective supervision nor have adequate ability to use their formal powers to take corrective action. * On average, countries in Western Europe demonstrated a much higher degree of compliance (above 90%) with BCP than their counterparts in other regions. * Africa and Western Hemisphere weak. Generally, high-income countries reflected a higher degree of compliance. TOPIC 8: CAPITAL ADEQUACY Overview * Adequate capital better able to withstand losses, provide credit through the business cycle and help promote public confidence in banking system. Importance of Capital Adequacy * Absorb unanticipated losses and preserve confidence in the FI * Protect uninsured depositors and other stakeholders * Protect FI insurance funds and taxpayers * Protect deposit insurance owners against increases in insurance premiums * To acquire real investments in order to provide financial services e. . equity financing is very important. Capital Adequacy * Capital too low banks may be unable to absorb high level of losses. * Capital too high banks may not be able to make the most efficient use of their resources. Constraint on credit availability. Pre-1988 * Banks regulated using balance sheet measures e. g. ratio of capital to assets. * Variations between countries re definitions, required ratios and enforcement of regulations. * 1980s: bank leverage increased, OBS derivatives trading increased. * LDC debt = major problem 1988 Basel Capital Accord (Basel I) * G10 agreed to Basel I Only covered credit risk * Capital / risk-adjusted assets > 8% * Tier 1 capital = shareholders equity and retained earnings * Tier 2 capital = additional internal and external resources e. g. loan loss reserves * Tier 1 capital / risk-adjusted assets > 4% * On-balance-sheet assets assigned to one of four categories * 0% – cash and government bonds * 20% – claims on OECD banks * 50% – residential mortgages * 100% – corporate loans, corporate bonds * Off-balance-sheet assets divided into contingent or guarantee contracts and FX/IR forward, futures, option and swap contracts. Two step process (i) derive credit equivalent amounts as product of FV and conversion factor then (ii) multiply amount by risk weight. * OBS market contracts or derivative instruments = potential exposure + current exposure. * Potential exposure: credit risk if counterparty defaults in the future. * Current exposure: cost of replacing a derivative securities contract at today’s prices. 1996 Amendment * Implemented in 1998 * Requires banks to measure and hold capital for market risk. * k is a multiplicative factor chosen by regulators (at least 3) VaR is the 99% 10-day value at risk SRC is the specific risk charge Total Capital = 0. 08 x [Credit risk RWA + Market risk RWA] where market risk RWA = 12. 5 x [k x VaR + SRC] Basel II (2004) * Implemented in 2007 * Three pillars 1. New minimum capital requirements for credit and operational risk 2. Supervisory review: more thorough and uniform 3. Market discipline: more disclosure * Only applied to large international banks in US * Implemented by securities companies as well as banks in EU Pillar 1: Minimum Capital Requirements * Credit risk measurement: * Standardised approach (external credit rating based risk weights) * Internal rating based (IRB) Market risk = unchanged * Operational risk: * Basic indicator: 15% of gross income * Standardised: multiplicative factor for income arising from each business line. * Advanced measurement approaches: assess 99. 9% worst case loss over one year. * Total capital = 0. 08 x [Credit risk RWA + market risk RWA + Operational risk RWA] Pillar 2: Supervisory Review * Importance of effective supervisory review of banks’ internal assessments of their overall risks. Pillar 3: Market discipline * Increasing transparency – public disclosure Basel 2. 5 (Implemented 2011) * Stressed VaR for market risk * Incremental risk charge Ensures products such as bonds and derivatives in the trading book have the same capital requirement that they would if they were in the banking book. * Comprehensive risk measure (re credit default correlations) Basel III (2010) * Considerably increase quality and quantity of banks capital * Macroprudential overlay – systemic risk * Allows time for smooth transition to new regime * Core capital only retained earnings and common shares * Reserves increased from 2% to 4. 5% * Capital conservation buffer – 2. 5% of RWA * Countercyclical capital buffer * Tracing/monitoring of liquidity funding Introduction of a maximum leverage ratio Capital Definitions and Requirements * Common equity > 4. 5% of RWA * Tier 1 > 6% of RWA * Phased implementation of capital levels stretching to Jan 1, 2015 * Phased implementation of capital definition stretching to Jan 1, 2018 Microprudential Features * Greater focus on common equity * Loss-absorbing during stress/crisis period capital conservation buffer * Promoting integrated management of market and counterparty credit risk. * Liquidity standard introduced introduced Jan 1, 2015 Introduced Jan 1, 2018 Available Stable Funding Factors

Required Stable Funding Factors Macroprudential Factors * Countercyclical buffer * Acts as a brake in good times of high credit growth and a decompressor to restrict credit during downturns. * Within a range of 0-2. 5% * Left to the discretion of national regulators * Dividends restricted when capital is below required level * Phased in between Jan 1, 2016 – Jan 1, 2019 * Leverage Ratio * Target 3% * Ratio of Tier 1 capital to total exposure > 3% * Introduced on Jan 1, 2018 after a transition period * SIFIs * Required to hold additional loss absorbency capital, ranging from 1-2. 5% in common equity
