Basel Accords in the context of "Central banking"

A bank is a financial institution that accepts deposits from the public and creates a demand deposit while simultaneously making loans. Lending activities can be directly performed by the bank or indirectly through capital markets.

As banks play an important role in financial stability and the economy of a country, most jurisdictions exercise a high degree of regulation over banks. Most countries have institutionalized a system known as fractional-reserve banking, under which banks hold liquid assets equal to only a portion of their current liabilities. In addition to other regulations intended to ensure liquidity, banks are generally subject to minimum capital requirements based on an international set of capital standards, the Basel Accords.

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.

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 It is now extended and partially superseded by Basel III.

The Basel II Accord was published in June 2004. It was a new framework for international banking standards, superseding the Basel I framework, to determine the minimum capital that banks should hold to guard against the financial and operational risks. The regulations aimed to ensure that the more significant the risk a bank is exposed to, the greater the amount of capital the bank needs to hold to safeguard its solvency and overall economic stability. Basel II attempted to accomplish this by establishing risk and capital management requirements to ensure that a bank has adequate capital for the risk the bank exposes itself to through its lending, investment and trading activities. One focus was to maintain sufficient consistency of regulations so to limit competitive inequality amongst internationally active banks.

Basel III is the third of three Basel Accords, a framework that sets international standards and minimums for bank capital requirements, stress tests, liquidity regulations, and leverage, with the goal of mitigating the risk of bank runs and bank failures. It was developed in response to the deficiencies in financial regulation revealed by the 2008 financial crisis and builds upon the standards of Basel II, introduced in 2004, and Basel I, introduced in 1988.

The Basel III requirements were published by the Basel Committee on Banking Supervision in 2010, and began to be implemented in major countries in 2012. Implementation of the Fundamental Review of the Trading Book (FRTB), published and revised between 2013 and 2019, has been completed only in some countries and is scheduled to be completed in others in 2025 and 2026. Implementation of the Basel III: Finalising post-crisis reforms (also known as Basel 3.1 or Basel III Endgame), introduced in 2017, was extended several times, and will be phased-in by 2028.
