Risk-weighted asset

Last updated

Risk-weighted asset (also referred to as RWA) is a bank's assets or off-balance-sheet exposures, weighted according to risk. [1] 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: [2]

Usually, different classes of assets have different risk weights associated with them. The calculation of risk weights is dependent on whether the bank has adopted the standardized or IRB approach under the Basel II framework. [3]

Some assets, such as debentures, are assigned a higher risk than others, such as cash or government securities/bonds. Since different types of assets have different risk profiles, weighting assets according to their level of risk primarily adjusts for assets that are less risky by allowing banks to discount lower-risk assets. In the most basic application, government debt is allowed a 0% "risk weighting" [4] - that is, they are subtracted from total assets for purposes of calculating the CAR.

A document was written in 1988 by the Basel Committee on Banking Supervision which recommends certain standards and regulations for banks. This was called Basel I, and the Committee came out with a revised framework known as Basel II. The main recommendation of this document is that banks should hold enough capital to equal at least 8% of its risk-weighted assets. [5] More recently, the committee has published another revised framework known as Basel III. [6] The calculation of the amount of risk-weighted assets depends on which revision of the Basel Accord is being followed by the financial institution. Most countries have implemented some version of this regulation. [7]

Operational risk is the risk of losses caused by flawed or failed processes, policies, systems or events that disrupt business operations. Employee errors, criminal activity such as fraud, and physical events are among the factors that can trigger operational risk. The process to manage operational risk is known as operational risk management. The definition of operational risk, adopted by the European Solvency II Directive for insurers, is a variation adopted from the Basel II regulations for banks: "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". 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. It is now extended and partially superseded by Basel III.

A capital requirement is the amount of capital a bank or other financial institution has to have as required by its financial regulator. This is usually expressed as a capital adequacy ratio of equity as a percentage of risk-weighted assets. These requirements are put into place to ensure that these institutions do not take on excess leverage and risk becoming insolvent. Capital requirements govern the ratio of equity to debt, recorded on the liabilities and equity side of a firm's balance sheet. They should not be confused with reserve requirements, which govern the assets side of a bank's balance sheet—in particular, the proportion of its assets it must hold in cash or highly-liquid assets. Capital is a source of funds not a use of funds.

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.

Basel I is the first Basel Accord. It arose from deliberations by central bankers from major countries during the late 1970s and 1980s. In 1988, the Basel Committee on Banking Supervision (BCBS) in Basel, Switzerland, published a set of minimum capital requirements for banks. It is also known as the 1988 Basel Accord, and was enforced by law in the Group of Ten (G-10) countries in 1992.

Capital Adequacy Ratio (CAR) is also known as Capital to Risk (Weighted) Assets Ratio (CRAR), is the ratio of a bank's capital to its risk. National regulators track a bank's CAR to ensure that it can absorb a reasonable amount of loss and complies with statutory Capital requirements.

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.

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.

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.

Basel III is the third Basel Accord, a framework that sets international standards for bank capital adequacy, stress testing, and liquidity requirements. Augmenting and superseding parts of the Basel II standards, it 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).

Under the Basel II guidelines, banks are allowed to use their own estimated risk parameters for the purpose of calculating regulatory capital. This is known as the internal ratings-based (IRB) approach to capital requirements for credit risk. Only banks meeting certain minimum conditions, disclosure requirements and approval from their national supervisor are allowed to use this approach in estimating capital for various exposures.

Basel III: Finalising post-crisis reforms, sometimes called the Basel III Endgame, Basel 3.1 or CRR3, 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 Capital Requirements Regulation(EU) No. 575/2013 is an EU law that aims to decrease the likelihood that banks go insolvent. With the Credit Institutions Directive 2013 the Capital Requirements Regulation 2013 reflects Basel III rules on capital measurement and capital standards.

The Fundamental Review of the Trading Book (FRTB), is a set of proposals by the Basel Committee on Banking Supervision for a new market risk-related capital requirement for banks.

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. See Basel III: Finalising post-crisis reforms.
