Episode: What is a Bank?
Release Date: July 5, 2025
Host: Dr. Andrew Temte, CFA
Introduction and Recap
In the latest episode of Saturday Morning Muse, host Dr. Andrew Temte builds upon the foundational concepts discussed in the previous week’s episode, which delved into the history of promissory notes and paper money. Dr. Temte highlights the evolution of money, emphasizing that both early coins and paper currency share the characteristic of possessing velocity—the frequency with which money circulates within an economy, fostering economic activity. He succinctly encapsulates this notion with the observation:
"All currency has velocity and flows through an economy. The more times currency is used in transactions, the more economic activity there is." (02:30)
Defining a Bank
To understand the transformation from promissory notes to modern currency, Dr. Temte introduces the concept of banking. He defines a bank in its simplest terms as:
"A financial institution that receives deposits from savers, makes loans to borrowers, and manages transactions." (04:15)
This definition lays the groundwork for dissecting the three core components of banking, which Dr. Temte explores in detail.
Components of Banking
1. Deposits
Deposits constitute the money placed into accounts at financial institutions for various purposes, including safekeeping, investment, or facilitating further financial transactions. Dr. Temte categorizes modern deposit types such as:
- Checking Accounts
- Savings Accounts
- Money Market Accounts
- Certificates of Deposit (CDs)
- Retirement Accounts
- Payroll Sweep Accounts
He notes that each type of deposit account serves distinct financial needs and will be explored in future episodes.
"A deposit is a quantity of money that is placed into an account at a financial institution for safekeeping, investment, or to make another financial transaction." (05:00)
2. Loans
Loans are financial transactions where banks advance money to borrowers for various purposes, including purchasing a car, a house, or funding business ventures. Dr. Temte enumerates the diverse applications of loans:
"You can borrow money for a car, a house, a boat, businesses, debt consolidation, education... the list goes on." (06:20)
Future episodes will provide an in-depth analysis of different loan types and their implications.
3. Transactions
In the context of banking, transactions encompass any activity such as deposits, loans, money transfers, payments, or investments. Dr. Temte explains that banks facilitate these transactions for a fee, which constitutes a significant portion of their revenue.
"Banks facilitate or manage transactions for a fee. The typical bank can earn a significant proportion of their revenue from transaction fees." (07:45)
Characteristics of Banks
Dr. Temte outlines several key characteristics that define banks and bankers:
-
Intermediaries:
Banks serve as middlemen connecting savers and borrowers, ensuring the efficient flow of funds within the economy. -
Security:
They provide a secure environment for storing money and valuables while diligently working to prevent fraud. -
Facilitators of Economic Velocity:
By managing banking relationships, banks sustain the flow and velocity of money, which is essential for a healthy economy. -
Ubiquity:
Modern banks are omnipresent, both physically with numerous branch locations and digitally through banking apps that enable 24/7 transactions. -
Profit-Seeking Entities:
Banks operate as businesses aiming to generate profit through transaction fees and the interest rate spread—the difference between the interest rates charged to borrowers and those paid to depositors."The interest rate spread is the difference between the rate the bank charges and receives for lending money to borrowers and the rate that it pays to savers or depositors." (09:30)
-
Advisors:
Bankers provide financial advice to both depositors and borrowers, aiding them in making informed financial decisions. -
Risk Managers:
Banks continuously manage their risk profiles to avoid pitfalls such as loan defaults or bank runs, where depositors panic and rush to withdraw their funds."If borrowers default on their loans, then the bank loses. If depositors want their money and the bank doesn't have it, then trust falls, depositors panic, and a bank run can occur." (11:10)
The Importance of a Healthy Banking Sector
Dr. Temte underscores the critical role that a healthy banking sector plays in maintaining a robust economy. He asserts:
"A healthy economy depends on a healthy banking sector." (12:00)
Case Study: The Great Recession of 2008-2009
To illustrate the pivotal role of banks, Dr. Temte examines the Great Recession of 2008-2009. He attributes the recession primarily to the collapse of the U.S. housing market, which was fueled by low interest rates, financial deregulation, and the proliferation of easy credit. During this period, banks neglected their responsibilities as risk managers by issuing loans to subprime borrowers—individuals with poor credit who were unlikely to repay their loans.
"Banks shirked their duty as risk managers and lent money to borrowers who had poor credit and couldn't afford to repay their loans." (13:50)
As housing prices began to decline, these subprime borrowers defaulted in large numbers, leading to massive losses for banks. The bankruptcy of major mortgage lender Lehman Brothers in September 2008 exacerbated the global recession, the effects of which linger, particularly in the housing market where supply remains below demand.
"Now, we're still feeling the effects of the Great Recession today, primarily in the housing market, where the supply of homes is less than the demand." (16:20)
Conclusion and Looking Ahead
Dr. Temte wraps up the episode by hinting at future discussions that will delve into the origins of modern banking, featuring historical figures and institutions like the Knights Templar, the Medici family, and the Bank of England.
"Next week, as promised, we're going to introduce a few examples of the original bankers—the OGs, the Knights Templar, the Medici family, and the Bank of England." (18:40)
He emphasizes the ongoing importance of understanding banking to navigate and improve economic landscapes effectively.
"Until next week, I wish you grace, dignity, and compassion." (19:30)
