How Commercial Banks Impact the Economy: Lending, Deposits, and More

Key Takeaways

• Commercial banks offer services like accepting deposits, lending money, and processing payments.
• Starting a commercial bank involves significant capital, regulatory hurdles, and detailed planning.
• Post-1999, commercial and investment banks’ roles are less distinct due to legislative changes.
• Commercial banks allocate capital by lending to individuals and businesses while balancing investor returns.
• Without commercial banks, basic financial operations and economic stability would be severely impacted.

Commercial banks are more than places to store money or get loans; they operate within a regulated system that connects everyday banking to the broader financial system. After the Glass-Steagall Act, commercial banks were separated from investment banks and focused on accepting deposits, lending, and providing financial services to individuals and businesses. Their role in supporting credit and economic activity makes them a core part of the financial ecosystem.

Defining a Commercial Bank in Today’s Financial Landscape

Between 1933 and 1999, it was fairly easy to tell banks apart, thanks to the Glass-Steagall Act. If you helped companies issue shares, you were an investment bank. If you were primarily concerned with deposits and lending, then you were a commercial bank. From the late 1990s onward, however, the ability to enforce Glass-Steagall as a black-and-white rule eroded and the act was effectively repealed.

Since then, the old distinction between a commercial bank and an investment bank is essentially meaningless. For example, as of March 31, 2024, JPMorgan Chase Bank is the largest commercial banks in the U.S. by assets; in 2012, the same bank was one of the lead underwriters in the Facebook initial public offering (IPO).

Important

Commercial banks provide a range of financial services to individuals and businesses so they can carry out simple financial tasks.

For better or worse, we’ve lost the issuance of securities and active investment in securities as defining actions that a commercial bank cannot take. Instead, we can look at the actions all commercial banks share.

Core Services Offered by Commercial Banks

• Accept deposits
• Lend money
• Process payments
• Issue bank drafts and checks
• Offer safety deposit boxes for items and documents

There are more actions, of course, and finer categories within this broad view. Commercial banks may offer other services such as brokering insurance contracts, giving investment advice, and so on. They also provide a wide variety of loans and offer other credit vehicles like cards and overdrafts. However, the common theme among these activities is that they are aimed at providing a financial service to an individual or business.

Establishing a Commercial Bank: From Vision to Operations

To understand commercial banking, it is worth looking at how they are established. Although big banks like JPMorgan Chase, Wells Fargo, and Citibank are well-known and global in scope, there are thousands of commercial banks in the United States alone.

Despite the seemingly large number, starting and operating a commercial bank is a long process due to the regulatory steps and capital needs. Rules vary by state, but in the U.S., an organizing group begins the process by securing several million dollars in seed capital. This capital brings together a management team with experience in the banking industry as well as a board.

Crafting the Vision for a New Commercial Ban

Once the board and management are set, a location is selected and the overall vision for the bank is created. The organizing group then sends its plan, along with information on the board and management, to regulators who review it and decide if the bank can be granted a charter. The review costs thousands of dollars and the plan may be sent back with recommendations that need to be addressed for approval.

Steps to Launching an Operational Commercial Bank

If the charter is granted, the bank must be operational within a year. In the next 12 months, the organizers must get their FDIC insurance paid, secure staff, buy equipment, and so on, as well as go through two more regulatory inspections before the doors can open.

Timeline for Launching a Commercial Bank

This timing on the entire process can vary, but including preparation before the first filing to regulators, it is measured in years, not months. To get to the stage where a bank can make money by leveraging deposited dollars as consumer loans, there need to be millions in capital, some of which can be raised in private circles and paid back through an eventual public share offering.

In theory, a charter bank can be 100% privately funded, but most banks go public because the shares become liquid, making it easier to pay out investors. Consequently, having an IPO in the original plan makes it easier to attract early-stage investors as well.

The Economic Impact of Commercial Banks

The process of launching a commercial bank foreshadows the overall role that these banks play in the economy. A commercial bank is basically a collection of investment capital in search of a good return. The bank—the building, people, processes, and services—is a mechanism for drawing in more capital and allocating in a way that the management and board believe will offer the best return. By allocating capital efficiently, the bank will be more profitable and the share price will increase.

From this view, a bank provides a service to the consumer mentioned earlier. But it also provides a service to investors by acting as a filter for who gets allocated how much capital. Banks that do both jobs will go on to be successes. Banks that don’t do one or either of these jobs may eventually fail. In the case of failure, the FDIC swoops in, protects depositors, and sees that the bank’s assets end up in the hands of a more successful bank.

How Is My Main Street Bank Different From a Commercial Bank?

The bank you use is almost certainly a commercial bank. While yours may be more locally owned and operated than a national chain bank like Citibank or Wells Fargo, it is still a commercial bank that offers deposit accounts, savings accounts, and other products, and uses the money you deposit to invest in stocks, securities, and so on.

Why Are Commercial Bank Deposits FDIC Insured?

Not too long ago, deposits at banks were not FDIC insured. This meant that if a bank collapsed as many did during the Great Depression, people who kept their savings at that bank lost everything. Now that deposits are insured, even if the bank you use goes under, your money is safe. FDIC insured deposits cover up to $250,000 per depositor, per insured bank, for each account ownership category.

What Would Happen Without Commercial Banks?

In a nutshell, if commercial banks suddenly disappeared, the economy would collapse. Credit cards and debit cards would stop working, automatic payments between individuals and businesses would stop, companies would lose investment capital, and the world as we know it would grind to a halt.

The Bottom Line

Commercial banks play a central role in the broader economic system by allocating capital for profit, primarily through lending and extending credit. While they may also invest in securities, these activities are often handled through separate investment arms. Ultimately, commercial banks balance customer service with responsible capital allocation to support economic activity and generate returns.
