, 1. Interest rates
- What are interest rates?
→ The amount of money a borrower promises to pay to the lender
- Why do we need interest rates?
→ Time value of money
- Risk-free rate
→ Credit risk
- The risk that a default by the borrower causes the lender not to be paid
- To determine the fair value of any financial asset
1.1 Time has value
If you want to be convinced to use / invest your money you need a return
At the core, the intrest rate allows us to make a difference between the flow of money today and in
the future
1.2 Time value of money
Moving money across time
→ 10 C today are different than 10 C tomorrow, why?
- 10 C today can be spent
- 10 C tomorrow cannot (no matter how trustworthy the counterpart).
The interest rate is the price to convert future money into today’s money (and the other way around)
No matter how trustworthy the borrower is, if you lend him money, you cannot use it today
1.3 Credit risk
The counterpart is important
→ 10 C tomorrow from Bill Gates are different than 10 C tomorrow from Angelo Luisi, why?
- Bill Gates is a multimillionaire
- I am not (no matter how good this class will be)
↑ the creditworthiness of the counterpart, ↓ the credit risk
↓ the credit risk, ↓ the interest rate.
Lower bound: Risk-free rate
à Even if the borrower is very credible, there will always be an intrest rate for the time, which has a
monetary value
