Operational risk is "the risk of a change in value caused by the fact that actual losses, incurred for inadequate or failed internal processes, people and systems, or from external events, differ from the expected losses". This definition, adopted by the European Solvency II Directive for insurers, is a variation adopted from the Basel II regulations for banks. The scope of operational risk is then broad, and can also include other classes of risks, such as fraud, security, privacy protection, legal risks, physical or environmental risks. Operational risks similarly may impact broadly, in that they can affect client satisfaction, reputation and shareholder value, all while increasing business volatility.
The Basel Accords refer to the banking supervision Accords issued by the Basel Committee on Banking Supervision (BCBS).
Basel II is the second of the Basel Accords,, which are recommendations on banking laws and regulations issued by the Basel Committee on Banking Supervision.
The Basel Committee on Banking Supervision (BCBS) is a committee of banking supervisory authorities that was established by the central bank governors of the Group of Ten countries in 1974. The committee expanded its membership in 2009 and then again in 2014. In 2019, the BCBS has 45 members from 28 Jurisdictions, consisting of Central Banks and authorities with responsibility of banking regulation. It provides a forum for regular cooperation on banking supervisory matters. Its objective is to enhance understanding of key supervisory issues and improve the quality of banking supervision worldwide. The Committee frames guidelines and standards in different areas – some of the better known among them are the international standards on capital adequacy, the Core Principles for Effective Banking Supervision and the Concordat on cross-border banking supervision. The Committee's Secretariat is located at the Bank for International Settlements (BIS) in Basel, Switzerland. The Bank for International Settlements (BIS) hosts and supports a number of international institutions engaged in standard setting and financial stability, one of which is BCBS. Yet like the other committees, BCBS has its own governance arrangements, reporting lines and agendas, guided by the central bank governors of the Group of Ten (G10) countries.
Tier 1 capital is the core measure of a bank's financial strength from a regulator's point of view. It is composed of core capital, which consists primarily of common stock and disclosed reserves, but may also include non-redeemable non-cumulative preferred stock. The Basel Committee also observed that banks have used innovative instruments over the years to generate Tier 1 capital; these are subject to stringent conditions and are limited to a maximum of 15% of total Tier 1 capital. This part of the Tier 1 capital will be phased out during the implementation of Basel III.
Tier 2 capital, or supplementary capital, includes a number of important and legitimate constituents of a bank's capital requirement. These forms of banking capital were largely standardized in the Basel I accord, issued by the Basel Committee on Banking Supervision and left untouched by the Basel II accord. National regulators of most countries around the world have implemented these standards in local legislation. In the calculation of regulatory capital, Tier 2 is limited to 100% of Tier 1 capital.
Advanced measurement approach (AMA) is one of three possible operational risk methods that can be used under Basel II by a bank or other financial institution. The other two are the Basic Indicator Approach and the Standardised Approach. The methods increase in sophistication and risk sensitivity with AMA being the most advanced of the three.
The term Advanced IRB or A-IRB is an abbreviation of advanced internal ratings-based approach, and it refers to a set of credit risk measurement techniques proposed under Basel II capital adequacy rules for banking institutions.
The term Foundation IRB or F-IRB is an abbreviation of foundation internal ratings-based approach, and it refers to a set of credit risk measurement techniques proposed under Basel II capital adequacy rules for banking institutions.
Probability of default (PD) is a financial term describing the likelihood of a default over a particular time horizon. It provides an estimate of the likelihood that a borrower will be unable to meet its debt obligations.
The term standardized approach refers to a set of credit risk measurement techniques proposed under Basel II, which sets capital adequacy rules for banking institutions.
In the context of operational risk, the standardized approach or standardised approach is a set of operational risk measurement techniques proposed under Basel II capital adequacy rules for banking institutions.
Loss given default or LGD is the share of an asset that is lost if a borrower defaults.
Exposure at default or (EAD) is a parameter used in the calculation of economic capital or regulatory capital under Basel II for a banking institution. It can be defined as the gross exposure under a facility upon default of an obligor.
The Capital Requirements Directives (CRD) for the financial services industry have introduced a supervisory framework in the European Union which reflects the Basel II and Basel III rules on capital measurement and capital standards.
Risk-weighted asset is a bank's assets or off-balance-sheet exposures, weighted according to risk. This sort of asset calculation is used in determining the capital requirement or Capital Adequacy Ratio (CAR) for a financial institution. In the Basel I accord published by the Basel Committee on Banking Supervision, the Committee explains why using a risk-weight approach is the preferred methodology which banks should adopt for capital calculation:
Basel III is a global, voluntary regulatory framework on bank capital adequacy, stress testing, and market liquidity risk. This third installment of the Basel Accords was developed in response to the deficiencies in financial regulation revealed by the financial crisis of 2007–08. It is intended to strengthen bank capital requirements by increasing minimum capital requirements, holdings of high quality liquid assets, and decreasing bank leverage.
During the financial crisis of 2007–2008, several banks, including the UK's Northern Rock and the U.S. investment banks Bear Stearns and Lehman Brothers, suffered a liquidity crisis, due to their over-reliance on short-term wholesale funding from the interbank lending market. As a result, the G20 launched an overhaul of banking regulation known as Basel III. In addition to changes in capital requirements, Basel III also contains two entirely new liquidity requirements: the net stable funding ratio (NSFR) and the liquidity coverage ratio (LCR).
The Basel III: Finalising post-crisis reform standards, sometimes called Basel 3.1 or Basel IV, are changes to international standards for bank capital requirements that were agreed by the Basel Committee on Banking Supervision (BCBS) in 2017 and are due for implementation in January 2023. They amend the international banking standards known as the Basel Accords.
The Standardized approach for counterparty credit risk (SA-CCR) is the capital requirement framework under Basel III addressing counterparty risk for derivative trades. It was published by the Basel Committee in March 2014.
