Topic 4.1: Financial Assets, Interest Rates, and Liquidity

Fundamental Principles of Lending and Interest

• Rationale for Interest Charges: Banks charge interest to borrowers as it serves as the "price of a loan." This ensures that banks receive compensation or "get something out of it" in exchange for providing capital.
• Definition of an Interest Rate: An interest rate is the specific amount charged by a lender to a borrower for the authorized use of money over a period of time.

Key Financial Definitions and Asset Characteristics

• Liquidity: This is defined as the ease and speed with which an asset can be converted into a medium of exchange (cash) without significant loss of value.
• Bonds:   - Bonds are interest-bearing assets.   - They are commonly issued by two primary entities: businesses or the government.
• Checking Accounts:   - These consist of funds deposited into a bank account.   - A defining characteristic is that these funds can be withdrawn by the depositor at any time "without any penalty."

The Inverse Relationship in Finance

• Interest Rates and Bond Prices: There is a fundamental inverse relationship between these two variables.   - As the interest rate increases, the price of existing bonds decreases ($\uparrow i \implies \downarrow P_{bond}$).   - Conversely, as the interest rate decreases, the price of bonds increases ($\downarrow i \implies \uparrow P_{bond}$).

Classification and Comparison of Financial Assets

• Core Financial Assets: To understand the financial landscape, one must be familiar with the following assets:   - Savings accounts   - Stocks   - Bonds   - Checking accounts   - Real estate   - Certificates of Deposit (CDs)
• The Risk and Return Pyramid: Financial assets are categorized based on their stability and growth potential:   - The Base: Certain assets are classified as "safe" and provide lower, more stable returns.   - The Ascent: As one moves up the pyramid toward more investment-heavy assets, there is "more potential for higher returns."   - Risk Correlation: Higher potential returns are directly correlated with "increasing risk."
• Specific Asset Comparison (Bonds vs. Stocks):   - Bonds: These are described as being "more secure" financial instruments.   - Stocks: These are characterized as "less" secure than bonds, given their exposure to market volatility and higher risk profile.
