Introduction
Amortizing bonds are a type of debt security that require periodic payments which include both interest and principal over the life of the bond. This structure contrasts with other types of bonds that may only require interest payments during the bond’s term, with the principal repaid at maturity.
Historical Context
The concept of amortizing bonds dates back to when long-term debt instruments began being used for public and private funding. Historically, they have been particularly useful for infrastructure projects, providing a predictable repayment schedule that aligns with revenue generation from the project.
Types/Categories
- Mortgage-Backed Securities (MBS): These bonds are secured by a pool of mortgages and include scheduled principal and interest payments.
- Asset-Backed Securities (ABS): Similar to MBS but backed by other types of assets like auto loans or credit card receivables.
- Municipal Bonds: Some municipalities issue amortizing bonds to fund public projects, providing regular cash flows that match their revenue streams.
- Corporate Bonds: Companies may issue these bonds to manage debt repayments in a more predictable manner.
Key Events
- 1938: The creation of the Federal National Mortgage Association (Fannie Mae) led to a significant increase in mortgage-backed securities, which are a major category of amortizing bonds.
- 1970: The formation of Ginnie Mae and Freddie Mac further popularized amortizing bonds in the mortgage market.
- 2008 Financial Crisis: Highlighted the risks associated with mortgage-backed securities, leading to more stringent regulations and oversight.
Mathematical Models
The amortization schedule of a bond can be determined using the following formula for the periodic payment \( P \):
where:
- \( P_0 \) is the principal loan amount
- \( r \) is the periodic interest rate
- \( n \) is the total number of payments
