Banking regulation and supervision refers to a form of financial regulation which subjects banks to certain requirements, restrictions and guidelines, enforced by a financial regulatory authority generally referred to as banking supervisor, with semantic variations across jurisdictions. By and large, banking regulation and supervision aims at ensuring that banks are safe and sound and at fostering market transparency between banks and the individuals and corporations with whom they conduct business.
Its main component is prudential regulation and supervision whose aim is to ensure that banks are viable and resilient ("safe and sound") so as to reduce the likelihood and impact of bank failures that may trigger systemic risk. Prudential regulation and supervision requires banks to control risks and hold adequate capital as defined by capital requirements, liquidity requirements, the imposition of concentration risk (or large exposures) limits, and related reporting and public disclosure requirements and supervisory controls and processes. Other components include supervision aimed at enforcing consumer protection, sometimes also referred to as conduct-of-business (or simply "conduct") regulation and supervision of banks, and anti-money laundering supervision that aims to ensure banks implement the applicable AML/CFT framework. Deposit insurance and resolution authority are also parts of the banking regulatory and supervisory framework. Bank (prudential) supervision is a form of "microprudential" policy to the extent it applies to individual credit institutions, as opposed to macroprudential regulation whose intent is to consider the financial system as a whole.

## Semantics

Banking supervision and regulation are closely intertwined, to the extent that in some jurisdictions (particularly the United States) the words "regulator" and "supervisor" are often used interchangeably in its context. Policy practice, however, makes a distinction between the setting of rules that apply to banks (regulation) and the oversight of their safety and soundness (prudential supervision), since the latter often entails a discretionary component or "supervisory judgment". The global framework for banking regulation and supervision, prepared by the Basel Committee on Banking Supervision, makes a distinction between three "pillars", namely regulation (Pillar 1), supervisory discretion (Pillar 2), and market discipline enabled by appropriate disclosure requirements (Pillar 3).
Bank licensing, which sets certain requirements for starting a new bank, is closely connected with supervision and usually performed by the same public authority. Licensing provides the licence holders the right to own and to operate a bank. The licensing process is specific to the regulatory environment of the jurisdiction where the bank is located. Licensing involves an evaluation of the entity's intent and the ability to meet the regulatory guidelines governing the bank's operations, financial soundness, and managerial actions. The supervisor monitors licensed banks for compliance with the requirements and responds to breaches of the requirements by obtaining undertakings, giving directions, imposing penalties or (ultimately) revoking the bank's license. Bank supervision may be viewed as an extension of the licence-granting process. Supervisory activities involve on-site inspection of the bank's records, operations and processes or evaluation of the reports submitted by the bank. Arguably the most important requirement in bank regulation that supervisors must enforce is maintaining capital requirements.
As banking regulation focusing on key factors in the financial markets, it forms one of the three components of financial law, the other two being case law and self-regulating market practices. Compliance with bank regulation is ensured by bank supervision.

## History

Banking regulation and supervision has emerged mostly in the 19th century and especially the 20th century, even though embryonic forms can be traced back to earlier periods. Landmark developments include the inception of U.S. federal banking supervision with the establishment of the Office of the Comptroller of the Currency in 1862; the creation of the U.S. Federal Deposit Insurance Corporation as the first major deposit guarantee and bank resolution authority in 1934; the creation of the Belgian Banking Commission, Europe's first modern banking supervisor in 1935; the start of formal banking supervision by the Bank of England in 1974, marking the eventual generalization of the practice among jurisdictions with large financial sectors; and the emergence of supranational banking supervision, first by the Eastern Caribbean Central Bank in 1983 and the Banking Commission of the West African Monetary Union in 1990 and then, at a much larger scale, with the start of European Banking Supervision in 2014.

## Objectives

Given the interconnectedness of the banking industry and the reliance that the national (and global) economy hold on banks, it is important for regulatory agencies to maintain control over the standardized practices of these institutions. Another relevant example for the interconnectedness is that the law of financial industries or financial law focuses on the financial (banking), capital, and insurance markets. Supporters of such regulation often base their arguments on the "too big to fail" notion. This holds that many financial institutions (particularly investment banks with a commercial arm) hold too much control over the economy to fail without enormous consequences. This is the premise for government bailouts, in which government financial assistance is provided to banks or other financial institutions who appear to be on the brink of collapse. The belief is that without this aid, the crippled banks would not only become bankrupt, but would create rippling effects throughout the economy leading to systemic failure. Compliance with bank regulations is verified by personnel known as bank examiners.
The objectives of bank regulation, and the emphasis, vary between jurisdictions. The most common objectives are:
* prudential—to reduce the level of risk to which bank creditors are exposed (i.e. to protect depositors)
* systemic risk reduction—to reduce the risk of disruption resulting from adverse trading conditions for banks causing multiple or major bank failures
* to avoid misuse of banks—to reduce the risk of banks being used for criminal purposes, e.g. laundering the proceeds of crime
* to protect banking confidentiality
* credit allocation—to direct credit to favored sectors
* it may also include rules about treating customers fairly and having corporate social responsibility.
Among the reasons for maintaining close regulation of banking institutions is the aforementioned concern over the global repercussions that could result from a bank's failure; the idea that these bulge bracket banks are "too big to fail". The objective of federal agencies is to avoid situations in which the government must decide whether to support a struggling bank or to let it fail. The issue, as many argue, is that providing aid to crippled banks creates a situation of moral hazard. The general premise is that while the government may have prevented a financial catastrophe for the time being, they have reinforced confidence for high risk taking and provided an invisible safety net. This can lead to a vicious cycle, wherein banks take risks, fail, receive a bailout, and then continue to take risks once again.

## Instruments and requirements
### Capital requirement

The capital requirement sets a framework on how banks must handle their capital in relation to their assets. Internationally, the Bank for International Settlements' Basel Committee on Banking Supervision influences each country's capital requirements. In 1988, the Committee decided to introduce a capital measurement system commonly referred to as the Basel Capital Accords. The latest capital adequacy framework is commonly known as Basel III. This updated framework is intended to be more risk sensitive than the original one, but is also a lot more complex.

### Reserve requirement

The reserve requirement sets the minimum reserves each bank must hold to demand deposits and banknotes. This type of regulation has lost the role it once had, as the emphasis has moved toward capital adequacy, and in many countries there is no minimum reserve ratio. The purpose of minimum reserve ratios is liquidity rather than safety. An example of a country with a contemporary minimum reserve ratio is Hong Kong, where banks are required to maintain 25% of their liabilities that are due on demand or within 1 month as qualifying liquefiable assets.
Reserve requirements have also been used in the past to control the stock of banknotes and/or bank deposits. Required reserves have at times been gold, central bank banknotes or deposits, and foreign currency.

### Corporate governance

Corporate governance requirements are intended to encourage the bank to be well managed, and is an indirect way of achieving other objectives. As many banks are relatively large, and with many divisions, it is important for management to maintain a close watch on all operations. Investors and clients will often hold higher management accountable for missteps, as these individuals are expected to be aware of all activities of the institution. Some of these requirements may include:
* to be a body corporate (i.e. not an individual, a partnership, trust or other unincorporated entity)
* to be incorporated locally, and/or to be incorporated under as a particular type of body corporate, rather than being incorporated in a foreign jurisdiction
* to have a minimum number of directors
* to have an organizational structure that includes various offices and officers, e.g. corporate secretary, treasurer/CFO, auditor, Asset Liability Management Committee, Privacy Officer, Compliance Officer etc. Also the officers for those offices may need to be approved persons, or from an approved class of persons
* to have a constitution or articles of association that is approved, or contains or does not contain particular clauses, e.g. clauses that enable directors to act other than in the best interests of the company (e.g. in the interests of a parent company) may not be allowed.

### Financial reporting and disclosure requirements

Among the most important regulations that are placed on banking institutions is the requirement for disclosure of the bank's finances. Particularly for banks that trade on the public market, in the US for example the Securities and Exchange Commission (SEC) requires management to prepare annual financial statements according to a financial reporting standard, have them audited, and to register or publish them. Often, these banks are even required to prepare more frequent financial disclosures, such as Quarterly Disclosure Statements. The Sarbanes–Oxley Act of 2002 outlines in detail the exact structure of the reports that the SEC requires.
In addition to preparing these statements, the SEC also stipulates that directors of the bank must attest to the accuracy of such financial disclosures. Thus, included in their annual reports must be a report of management on the company's internal control over financial reporting. The internal control report must include: a statement of management's responsibility for establishing and maintaining adequate internal control over financial reporting for the company; management's assessment of the effectiveness of the company's internal control over financial reporting as of the end of the company's most recent fiscal year; a statement identifying the framework used by management to evaluate the effectiveness of the company's internal control over financial reporting; and a statement that the registered public accounting firm that audited the company's financial statements included in the annual report has issued an attestation report on management's assessment of the company's internal control over financial reporting. Under the new rules, a company is required to file the registered public accounting firm's attestation report as part of the annual report. Furthermore, the SEC added a requirement that management evaluate any change in the company's internal control over financial reporting that occurred during a fiscal quarter that has materially affected, or is reasonably likely to materially affect, the company's internal control over financial reporting.

### Credit rating requirement

Banks may be required to obtain and maintain a current credit rating from an approved credit rating agency, and to disclose it to investors and prospective investors. Also, banks may be required to maintain a minimum credit rating. These ratings are designed to provide color for prospective clients or investors regarding the relative risk that one assumes when engaging in business with the bank. The ratings reflect the tendencies of the bank to take on high risk endeavors, in addition to the likelihood of succeeding in such deals or initiatives. The rating agencies that banks are most strictly governed by, referred to as the "Big Three" are the Fitch Group, Standard and Poor's and Moody's. These agencies hold the most influence over how banks (and all public companies) are viewed by those engaged in the public market. Following the 2007–2008 financial crisis, many economists have argued that these agencies face a serious conflict of interest in their core business model. Clients pay these agencies to rate their company based on their relative riskiness in the market. The question then is, to whom is the agency providing its service: the company or the market?
European financial economics experts – notably the World Pensions Council (WPC) have argued that European powers such as France and Germany pushed dogmatically and naively for the adoption of the "Basel II recommendations", adopted in 2005, transposed in European Union law through the Capital Requirements Directive (CRD). In essence, they forced European banks, and, more importantly, the European Central Bank itself, to rely more than ever on the standardized assessments of "credit risk" marketed aggressively by two US credit rating agencies – Moody's and S&P, thus using public policy and ultimately taxpayers' money to strengthen anti-competitive duopolistic practices akin to exclusive dealing. Ironically, European governments have abdicated most of their regulatory authority in favor of a non-European, highly deregulated, private cartel.

### Large exposures restrictions

Banks may be restricted from having imprudently large exposures to individual counterparties or groups of connected counterparties. Such limitation may be expressed as a proportion of the bank's assets or equity, and different limits may apply based on the security held and/or the credit rating of the counterparty. Restricting disproportionate exposure to high-risk investment prevents financial institutions from placing equity holders' (as well as the firm's) capital at an unnecessary risk.

### Activity and affiliation restrictions

In the US in response to the Great Depression of the 1930s, President Franklin D. Roosevelt's under the New Deal enacted the Securities Act of 1933 and the Glass–Steagall Act (GSA), setting up a pervasive regulatory scheme for the public offering of securities and generally prohibiting commercial banks from underwriting and dealing in those securities. GSA prohibited affiliations between banks (which means bank-chartered depository institutions, that is, financial institutions that hold federally insured consumer deposits) and securities firms (which are commonly referred to as "investment banks" even though they are not technically banks and do not hold federally insured consumer deposits); further restrictions on bank affiliations with non-banking firms were enacted in Bank Holding Company Act of 1956 (BHCA) and its subsequent amendments, eliminating the possibility that companies owning banks would be permitted to take ownership or controlling interest in insurance companies, manufacturing companies, real estate companies, securities firms, or any other non-banking company. As a result, distinct regulatory systems developed in the United States for regulating banks, on the one hand, and securities firms on the other.

## Bank supervisors

Most jurisdictions designate one public authority as their national prudential supervisor of banks: e.g. the National Administration of Financial Regulation in China, the Financial Services Agency in Japan, or the Prudential Regulation Authority in the United Kingdom. The European Union and United States have more complex setups in which multiple organizations have authority over bank supervision.

### European Union

The European Banking Authority plays a key role in EU banking regulation, but is not a banking supervisor. In the banking union (which includes the euro area as well as countries that join on a voluntary basis, lately Bulgaria), the European Central Bank, through its supervisory arm also known as ECB Banking Supervision, is the hub of banking supervision and works jointly with national bank supervisors, often referred to in that context as "national competent authorities" (NCAs). ECB Banking Supervision and the NCAs together form European Banking Supervision, also known as the Single Supervisory Mechanism. Countries outside the banking union rely on their respective national banking supervisors.

### United States

The United States relies on state-level bank supervisors (or "state regulators", e.g. the New York State Department of Financial Services), and at the federal level on a number of agencies involved in the prudential supervision of credit institutions: for banks, the Federal Reserve, Office of the Comptroller of the Currency, and Federal Deposit Insurance Corporation; and for other credit institutions, the National Credit Union Administration and Federal Housing Finance Agency.
