Certificate of Deposit (CD): A Secure Savings Instrument

A comprehensive article on Certificate of Deposit (CD), including its historical context, types, key events, detailed explanations, mathematical models, applicability, examples, and more.

Historical Context

Certificates of Deposit (CDs) have a long-standing history as a secure investment vehicle. CDs gained popularity in the early 20th century as banks sought ways to attract longer-term deposits. Over time, they became a staple in personal finance, known for their safety and fixed interest returns.

Types/Categories of CDs

• Traditional CDs: Fixed interest rate and term.
• Bump-Up CDs: Allows the holder to request an interest rate increase if rates rise.
• Step-Up CDs: Interest rate increases at predetermined intervals.
• Liquid CDs: Permit withdrawal of part of the deposit without penalty.
• Brokered CDs: Sold by brokerage firms, often offering higher interest rates.

Key Events

• 1933: Introduction of FDIC insurance increased the popularity of CDs.
• 1980s: Interest rate volatility led to innovations like bump-up and step-up CDs.

Detailed Explanations

CDs are time deposits where an individual agrees to deposit a sum of money for a fixed term. In exchange, the bank pays a fixed interest rate that is often higher than regular savings accounts. At the end of the term (maturity), the depositor receives the initial deposit plus accrued interest.

Mathematical Models

Calculating Interest Earned

The interest earned on a CD can be calculated using the formula:

$$ I = P \times r \times t $$

Where:

• \( I \) = Interest earned
• \( P \) = Principal amount
• \( r \) = Annual interest rate
• \( t \) = Time period (in years)
