BKM15 Flashcards
spot rate
the interest rate that applies from time 0 to time t
can be thought of as the yield to maturity on zero-coupon bonds
short rate
interest rate that will apply during a future time interval
forward rate
expected future short rate
terminal value
“A” is invested for “n” years at a rate of “R”, compounded “m” times per annum is: A * (1 + R/m)^mn
Terminal value if compounded continuously: Ae^Rn
Yield curve
graph that shows relationship between interest rate and time to maturity
pure yield curve
-curve is generally upward sloping but can deviate
2 theories of term structure/shape of the curve
expectations hypothesis
liquidity preference theory
Expectations Hypothesis
the forward rate = expected future short rate
-expected yields on bonds of different maturities reflect market expectations of future short rates
short term and long term investors
Short term: an investor who needs money in short term would prefer to purchase a short term bond; would be subject to interest rate risk if purchased long term
Long term: investor who needs money in long term would prefer a long term bond; would be subject to reinvestment risk if purchased short term
Liquidity Preference Theory
the shape of the yield curve will be influenced by the proportions of the different term investors
- if short term investors dominate the market, forward rates will exceed expected spot rate, which will produce rising yield curve
- if long term investors dominate, forward rates will be lower than expected short rates
forward rates should be > expected future spot rates
Bond investors are dominantly short-term; to attract them to hold long-term bond
the yield rate must be higher. This implies that forward rate must be higher than the expected short rate in the future.
if downward sloping
short rates must be expected to decrease even more than under expectations hypothesis because risk premium exits for longer maturities and long term bonds have a greater amount of demand related to supply than short term
despite fact that yield curve is affected by other factors like liquidity premium
it can still provide signs about future business cycle
- if curve has a steep positive rise, it is still likely that the market expects an expansion in economic activity
- if curve is sloping downward, it is likely that interest rates are expected to decline
On-the-run yield curve
This plots the yield as a function of recently issued coupon bonds selling at or near par value
investors tend to choose
shorter term investments if yield is the same as longer term yield
borrowers prefer
longer term if yields are the same
