Interest Rates Flashcards
Why is interest charged?
- The interest rate on a loan should cover the opportunity costs of supplying credit so that the interest should include:
- Compensation for inflation
- Compensation for default risk
- Compensation for the opportunity cost of waiting (interest)
What is the future value of a 1 year investment?
The future value of an investment (principal) in one year (FV1) with an interest rate i:
Principal x (1 + i) = FV1
What is the future value of a n year investment?
Principal x (1+i)^n = FVn
What is discounting and what is the equality?
- Discounting is the process of finding the present value of funds that will be received in the future
- Lets you compare financial assets
- Discounting: PV = FVn / (1+i)^n
What is the price of an asset?
- The price of a financial asset is equal to the PV of the payments to be receiving from owning it
- Passet = PV of payments received
- For either debt or equity assets
- Passet = PV of payments received
What is a simple loan?
The borrower receives from the lender an amount called the principal and agrees to repay the lender the principal plus interest on a specific date when the loan matures
What is a fixed payment loan?
Requires the borrower to make regular periodic payments of principal and interest to the lender
What is a discount loan?
The borrower repays the amount of the loan in a single payment at maturity but receives less than the face value of the bon initially
What is a coupon bond?
Requires multiple payments of interest on a regular basis, and a payment of the face value at maturity
What is face value?
Face value (or par value): amount to be repaid by the bond issuer (borrower) at maturity
What is a coupon?
Coupon: annual fixed dollar amount of interest paid by the issuer of the bond to the buyer
What is a coupon rate?
Coupon rate: the value of the coupon expressed as a percentage of the face value of the bond
What is a coupon yield?
Current yield: the value of the coupon expressed as a percentage of the current price
What is the maturity of a coupon bond?
length of time before the bond expires and the issuer makes the face value payment to the buyer
Pcoupon bonds =
- Pcoupon bonds = C/(1+i)^1 + … + C/(1+i)^n + FaceValue/(1+i)^n
- Pcoupon bonds = PV of holding coupon bonds
- Inverse relationship between i and P
What is yield to maturity?
- The interest rate i that makes the present value of the payments from an asset equal to the asset’s price today
- i where PVasset = Passet
- i where PV of future payments = value today
What is the YTM of a fixed payment/student loan?
- For a fixed payment loan with fixed payments FP and a maturity of n years:
- Loan Value = FP/(1+i) + … + FP/(1+i)^n
What is the YTM of a simple loan?
Loan = repayment/(1+i)^n
What is the TYM of a discount loan?
- A one-year discount bond that sells for price P with face value FV
- i = (FV - P)/P
- P = FV/(1+i)^n
What is the YTM of a coupon bond?
- For a bond that makes coupon payments (C = coupon rate x FV) and matures in n years:
- P = C/(1+i) + … + C/(1+i)n + FaceValue/(1+i)n
- Need to calculate i:
- YTM = (C + ((FV - Pbond)/n)) / ((FV + Pbond)/2)
What is the YTM of a perpetuity?
A perpetuity does not mature, the priced of a coupon bond that pays an infinite number of coupons: P = C/i
What is the correlation between Bond Yields and Maturities?
- If interest rates on newly issued bonds rise, the prices of existing bonds will fall
- If interest rates rise, existing bonds issued with lower interest rates become less desirable to investors, and their prices fall
- Yield to maturity and Bond prices move in opposite directions
What is rate of return?
`- Return is a security’s total earnings
- For a bond, its return is the coupon payment plus the change in it’s price
- The rate of returns (R) is the return on a security as a % of the initial price
R =
- For a bond, R equal the coupon payment plus the change in the price of a bond divided by the initial price:
- R = (C + Capital Gain) / Initial P
What is interest rate risk?
- The risk that the price of a financial asset will fluctuate in response to changes in the market interest rate
- Bonds with fewer years to maturity will be less affected by a change in market interest rates
- The longer the maturity, the lower (more negative) your return after one year of holding the bond (when the interest rate increases)
Fisher equation?
r = i - πe
What are the determinants of portfolio choice?
- Saver’s wealth
- Expected rate of return from different investments
- The degrees of risk in different ivnestments
- The liquidity of different investments
- The cost of acquiring information about different investments
- Diversification
How does a saver’s wealth affect portfolio choice?
An increase in wealth generally increases the quantity demanded for most financial assets
What is the EV of different investments?
Expected return = (P1 * Value1) + (P2 * Value2)
How does liquidity affect portfolio choice?
The greater an asset’s liquidity, the more desirable the asset is to investors
How does the cost of acquiring information about different investments affect portfolio choice?
All else being equal, investors will accept a lower return on an asset that has lower costs of acquiring information
What is diversification and what types are there?
- Dividing wealth among many different assets to reduce risk
- Market (systematic) risk is risk that is common to all assets of a certain type
- Idiosyncratic (unsystematic) risk is risk that pertains to a particular asset rather than the market on the whole
How are a bonds price and yield to maturity linked and what does this imply?
- A bonds price P and its yield to maturity i are linked by Pcoupon bonds = C/(1+i)1 + … + C/(1+i)n + FV/(1+i)n
- Because C and FV do no change, once we know P in the bond market, we have determined equilibrium i
What factors shift bond demand?
- Wealth
- Expected return on bonds
- Risk
- Liquidity
- Information costs
- Expected inflation
What factors shift bond supply?
- Expected pretax profitability of physical capital investments
- Business taxes
- Expected inflation
- Government tax credits
- Government borrowing
How does wealth shift bond demand?
`An increase in wealth will shift the demand curve to the right
How does expected return shift bond demand?
- Increase in expected return relative to other assets (lower expected future interest rates), demand will shift right
- Higher expected future interest rates drops demand!
- Expected return on other assets is opposite
