What is a Bank?

A Bank is a financial institution that is licensed to accept deposits and make loans. Banks can also provide financial services like money management, currency exchange, and secure deposit boxes. There are many different types of banks, including retail banks, corporate or commercial banks, and investment banks. Banks are governed by the country’s government and central banks.

Understanding Banks

Banks are an essential element of the economy as they offer critical services to both businesses and consumers. As financial service providers, they offer you a secure location to keep your money. With a range of accounts, including savings and checking accounts and the certificates of deposits (CDs), they allow you to perform routine banking transactions such as deposits, withdrawals, check writing, and payment for bills. You can also conserve your money and earn interest from your investments. The funds stored in many banks are federally protected through the Federal Deposit Insurance Corporation (FDIC) for up to $250,000 for individuals’ depositors and $500,000 for joint deposits.1

The bank will lend the money you deposit to the bank – short-term cash–to other banks for long-term loans like car loans, mortgages, credit cards, and other debt-related vehicles. This helps to increase liquidity in the market. This generates money and keeps the supply running. They also offer credit options for both corporations and individuals.

As with all businesses, one of the main goals of banks is to generate profits for their shareholders. For the majority of banks, their directors are the shareholders. They do this by charging higher interest on loans and other debts they offer to borrowers than they charge to those who use their savings accounts. For instance, a bank that offers 1% interest on savings accounts and charges 6% interest on loans generates a net gain of five percent for its shareholders.


How does a bank function?

In simple terms, a bank is a company that uses the money customers deposit into their savings and checking accounts to fund loans for both businesses and individuals. Banks typically make money from the interest they earn from their loans and pay part of it back to their customers in interest on savings accounts.

For a bank to operate, it requires a charter or license overseen by a regulatory. Within the U.S., there are national, and state charters that depend on the reach of a bank, and the three primary regulators of banks comprise The Federal Reserve, the Office of the Comptroller of the Currency, and the Federal Deposit Insurance Corporation. Suppose you feel that a bank has unfairly treated you. In that case, you can file complaints to the supervisor or with the Consumer Financial Protection Bureau.

Banks do not offer financial services, including mail-orders at post offices, gift cards sold at retail stores, and wire transfer and cash-in-check services available at Western Union locations. If the bank fails, you can get your money in savings and checking accounts. However, only banks are covered by FDIC insurance when you want to store your funds securely.


Nonbank organizations, like online brokers and neobanks, can collaborate with banks to provide their customers with FDIC-insured accounts, including checking accounts and cash management accounts.

Type of Banks

There are a variety of technical classifications — commercial bank, savings bank, etc. However, the most straightforward method to think of banks is to group them based on their size as well as whether or not they are branch-based they do not. Here’s a quick breakdown:

National Banks

National banks are among the largest U.S. banks with large ATMs and branches, robust mobile applications, and a wide range of products and services for business, the general public, and large commercial clients. The phrase “national bank” can refer to brick-and-mortar banks or online-only ones. (Learn the details about banks that are national and the 20 biggest banks across the U.S.) There are also international bank divisions.

Regional banks

Regional banks are mid-sized institutions focused on particular regions of the country. They can have branches in several states.

community banks

Community banks can be described as local, small institutions that may be the only bank that is physically located in an area, particularly in rural areas.


Online banks

Online banks are online-based businesses that allow customers to interact with them via websites and, typically though not necessarily, through a mobile application. They do not always provide all kinds of accounts and loans that you’ll find in traditional brick-and-mortar banks. (See more on online banks. )

Another type of bank you’ll read about in the news could affect your financial situation and personal finances even if you’re not able to join as a client:

Central banks

Central banks are banks run by bankers that allow a country’s financial system to function by setting monetary policy and generating money and other activities. Central banks are the U.S.’s Central banks, called the Federal Reserve. A central bank’s actions directly affect you, like when the Fed increases its interest rates.

How are banks regulated?

U.S. banks were under examination following the 2008 financial meltdown in global markets. The banking regulatory framework has since been slackened in the aftermath. U.S. banks are regulated on a national or state level. The bank is subject to regulation in both groups based on its structure. State banks are overseen by the state’s department of banks or department of financial institutions. This department is typically in charge of regulating topics like permitted practices, the number of interest banks can offer, and checking and auditing banks.

National banks are controlled by the Comptroller of the Currency (OCC). OCC regulations mainly concern banks’ capital level, asset quality, and liquidity. In addition, banks that have FDIC insurance are also governed under the FDIC.

The Dodd-Frank Wall Street Reform and Consumer Protection Act was approved in the 2010 election to reduce the risk in the U.S. financial system following the financial crisis. The law requires that significant banks rate whether they have enough capital to operate in challenging economic conditions. The annual evaluation is known as a stress test.
