Bank run in the context of "Panic of 1907"

The interbank lending market is a market in which banks lend funds to one another for a specified term. Most interbank loans are for maturities of one week or less, the majority being overnight. Such loans are made at the interbank rate (also called the overnight rate if the term of the loan is overnight). A sharp decline in transaction volume in this market was a major contributing factor to the collapse of several financial institutions during the 2008 financial crisis.

Banks are typically required to hold reserves of an adequate amount of liquid assets, such as cash, to manage any potential bank runs by customers. To remain compliant, those banks with less than the required liquidity will borrow money and pay interest in the interbank market, while those with excess liquid assets will lend money and receive interest.

A financial crisis is any of a broad variety of situations in which some financial assets suddenly lose a large part of their nominal value. A broader reduction of economic activity affecting the whole economy is known as an economic crisis. In the 19th and early 20th centuries, many financial crises were associated with banking panics, and many recessions coincided with these panics. Other situations that are often called financial crises include stock market crashes and the bursting of other financial bubbles, currency crises, and sovereign defaults. Financial crises directly result in a loss of paper wealth but do not necessarily result in significant changes in the real economy (for example, the crisis resulting from the famous tulip mania bubble in the 17th century).

Many economists have offered theories about how financial crises develop and how they could be prevented. There is little consensus and financial crises continue to occur from time to time. It is apparent however that a consistent feature of both economic (and other applied finance disciplines) is the obvious inability to predict and avert financial crises. This realization raises the question as to what is known and also capable of being known (i.e. the epistemology) within economics and applied finance. It has been argued that the assumptions of unique, well-defined causal chains being present in economic thinking, models and data, could, in part, explain why financial crises are often inherent and unavoidable.

The 2008 financial crisis, also known as the global financial crisis (GFC) or the Panic of 2008, was a major worldwide financial crisis centered in the United States. The causes included excessive speculation on property values by both homeowners and financial institutions, leading to the 2000s United States housing bubble. This was exacerbated by predatory lending for subprime mortgages and by deficiencies in regulation. Cash out refinancings had fueled an increase in consumption that could no longer be sustained when home prices declined. The first phase of the crisis was the subprime mortgage crisis, which began in early 2007, as mortgage-backed securities (MBS) tied to U.S. real estate, and a vast web of derivatives linked to those MBS, collapsed in value. A liquidity crisis spread to global institutions by mid-2007 and climaxed with the bankruptcy of Lehman Brothers in September 2008, which triggered a stock market crash and bank runs in several countries. The crisis exacerbated the Great Recession, a global recession that began in mid-2007, as well as the United States bear market of 2007–2009. It was also a contributor to the 2008–2011 Icelandic financial crisis and the euro area crisis.

During the 1990s, the U.S. Congress had passed legislation that intended to expand affordable housing through looser financing rules, and in 1999, parts of the 1933 Banking Act (Glass–Steagall Act) were repealed, enabling institutions to mix low-risk operations, such as commercial banking and insurance, with higher-risk operations such as investment banking and proprietary trading. As the Federal Reserve ("Fed") lowered the federal funds rate from 2000 to 2003, institutions increasingly targeted low-income homebuyers, largely belonging to racial minorities, with high-risk loans; this development went unattended by regulators. As interest rates rose from 2004 to 2006, the cost of mortgages rose and the demand for housing fell; in early 2007, as more U.S. subprime mortgage holders began defaulting on their repayments, lenders went bankrupt, culminating in the bankruptcy of New Century Financial in April. As demand and prices continued to fall, the financial contagion spread to global credit markets by August 2007, and central banks began injecting liquidity. In March 2008, Bear Stearns, the fifth-largest U.S. investment bank, was sold to JPMorgan Chase in a "fire sale" backed by Fed financing.

A central bank, reserve bank, national bank, or monetary authority is an institution that manages the monetary policy of a country or monetary union. In contrast to a commercial bank, a central bank possesses a monopoly on increasing the monetary base. Many central banks also have supervisory or regulatory powers to ensure the stability of commercial banks in their jurisdiction, to prevent bank runs, and, in some cases, to enforce policies on financial consumer protection, and against bank fraud, money laundering, or terrorism financing. Central banks play a crucial role in macroeconomic forecasting, which is essential for guiding monetary policy decisions, especially during times of economic turbulence.

Central banks in most developed nations are usually set up to be institutionally independent from political interference, even though governments typically have governance rights over them, legislative bodies exercise scrutiny, and central banks frequently do show responsiveness to politics.

The Federal Deposit Insurance Corporation (FDIC) is a United States government corporation supplying deposit insurance to depositors in American commercial banks and savings banks. The FDIC was created by the Banking Act of 1933, enacted during the Great Depression to restore trust in the American banking system. More than one-third of banks failed in the years before the FDIC's creation, and bank runs were common. The insurance limit was initially US$2,500 per ownership category, and this has been increased several times over the years. Since the enactment of the Dodd–Frank Wall Street Reform and Consumer Protection Act in 2010, the FDIC insures deposits in member banks up to $250,000 per ownership category. FDIC insurance is backed by the full faith and credit of the government of the United States, and according to the FDIC, "since its start in 1933 no depositor has ever lost a penny of FDIC-insured funds".

Deposits placed with non-bank fintech financial technology companies are not protected by the FDIC against failure of the fintech company. If the company places the money in an FDIC-insured bank account consumers are protected only under some conditions.

The Basel Accords refer to the banking supervision accords (recommendations on banking regulations) issued by the Basel Committee on Banking Supervision (BCBS).

Basel I was developed through deliberations among central bankers from major countries. In 1988, the Basel Committee published a set of minimum capital requirements for banks. This is also known as the 1988 Basel Accord, and was enforced by law in the Group of Ten (G-10) countries in 1992. A new set of rules known as Basel II was developed and published in 2004 to supersede the Basel I accords. Basel III was a set of enhancements to in response to the 2008 financial crisis. It does not supersede either Basel I or II but focuses on reforms to the Basel II framework to address specific issues, including related to the risk of a bank run.
