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.
The Committee was formed in response to the messy liquidation of Cologne-based Herstatt Bank in 1974. On 26 June 1974 a number of banks had released Deutschmarks (the German currency) to the Herstatt Bank in exchange for dollar payments deliverable in New York City. Due to differences in the time zones, there was a lag in the dollar payment to the counterparty banks; during this lag period, before the dollar payments could be effected in New York, the Herstatt Bank was liquidated by German regulators.
This incident prompted the G-10 nations to form the Basel Committee on Banking Supervision in late 1974, under the auspices of the Bank for International Settlements (BIS) located in Basel, Switzerland.
Basel I, that is, the 1988 Basel Accord, is primarily focused on credit risk and appropriate risk-weighting of assets. Assets of banks were classified and grouped in five categories according to credit risk, carrying risk weights of 0% (for example cash, bullion, home country debt like Treasuries), 20% (securitisations such as mortgage-backed securities (MBS) with the highest AAA rating), 50% (municipal revenue bonds, residential mortgages), 100% (for example, most corporate debt), and some assets given no rating. Banks with an international presence are required to hold capital equal to 8% of their risk-weighted assets (RWA).
The tier 1 capital ratio = tier 1 capital / all RWA
The total capital ratio = (tier 1 + tier 2 capital) / all RWA
Leverage ratio = total capital/average total assets
Banks are also required to report off-balance-sheet items such as letters of credit, unused commitments, and derivatives. These all factor into the risk weighted assets, which are reported to regulators. In the United States, the report is typically submitted to the Federal Reserve Bank as HC-R for the bank-holding company and submitted to the Office of the Comptroller of the Currency (OCC) as RC-R for just the bank.
From 1988 this framework was progressively introduced in member countries of G-10, comprising 13 countries as of 2013 [update] : Belgium, Canada, France, Germany, Italy, Japan, Luxembourg, Netherlands, Spain, Sweden, Switzerland, United Kingdom and the United States.
Over 100 other countries also adopted, at least in name, the principles prescribed under Basel I. The efficacy with which the principles are enforced varies, even within nations of the Group.
Basel I incentivized global banks to lend to members of the OECD and the IMF's General Arrangements to Borrow (GAB) while disincentivizing loans to non-members of these institutions. [1]
The global financial system is the worldwide framework of legal agreements, institutions, and both formal and informal economic action that together facilitate international flows of financial capital for purposes of investment and trade financing. Since emerging in the late 19th century during the first modern wave of economic globalization, its evolution is marked by the establishment of central banks, multilateral treaties, and intergovernmental organizations aimed at improving the transparency, regulation, and effectiveness of international markets. In the late 1800s, world migration and communication technology facilitated unprecedented growth in international trade and investment. At the onset of World War I, trade contracted as foreign exchange markets became paralyzed by money market illiquidity. Countries sought to defend against external shocks with protectionist policies and trade virtually halted by 1933, worsening the effects of the global Great Depression until a series of reciprocal trade agreements slowly reduced tariffs worldwide. Efforts to revamp the international monetary system after World War II improved exchange rate stability, fostering record growth in global finance.
Credit risk is the possibility of losing a lender holds due to a risk of default on a debt that may arise from a borrower failing to make required payments. In the first resort, the risk is that of the lender and includes lost principal and interest, disruption to cash flows, and increased collection costs. The loss may be complete or partial. In an efficient market, higher levels of credit risk will be associated with higher borrowing costs. Because of this, measures of borrowing costs such as yield spreads can be used to infer credit risk levels based on assessments by market participants.
Fractional-reserve banking is the system of banking in all countries worldwide, under which banks that take deposits from the public keep only part of their deposit liabilities in liquid assets as a reserve, typically lending the remainder to borrowers. Bank reserves are held as cash in the bank or as balances in the bank's account at the central bank. Fractional-reserve banking differs from the hypothetical alternative model, full-reserve banking, in which banks would keep all depositor funds on hand as reserves.
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.
Herstatt Bank was a privately owned bank in the German city of Cologne. It went bankrupt on 26 June 1974, an event widely referred to as the Herstatt crisis. Herstatt's failure specifically highlighted the importance of settlement risk in foreign-exchange markets, which became correspondingly known as Herstatt risk.
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.
Loss given default or LGD is the share of an asset that is lost if a borrower defaults.
A structured investment vehicle (SIV) is a non-bank financial institution established to earn a credit spread between the longer-term assets held in its portfolio and the shorter-term liabilities it issues. They are simple credit spread lenders, frequently "lending" by investing in securitizations, but also by investing in corporate bonds and funding by issuing commercial paper and medium term notes, which were usually rated AAA until the onset of the financial crisis. They did not expose themselves to either interest rate or currency risk and typically held asset to maturity. SIVs differ from asset-backed securities and collateralized debt obligations in that they are permanently capitalized and have an active management team.
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.
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 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.
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 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.
