Lecture 8- Interest rate risk management and Hedging Instruments (Forwards and Swaps) Flashcards
What is the term structure of interest rates?
A set of interest rates for a class of assets for a range of terms
What is a yield curve?
A graph of the term structure of interest rates at a particular point in time
a) Normal
b) Inverse
c) Flat
a) Normal: slopes upward because shorter term rates are lower than longer term rates
b) Inverse: Downward- because longer term rates are lower than shorter term rates
c) Flat: The curve is horizontal
How are yield curves constructed and on what types of securities?
1) Constructed from the yields on TRADED SECURITIES (rather than bank deposits)
2) The securities need to have little or no credit and liquidity risk- therefore BABs and Treasury bonds are used
3) The yields need to be calculated on a single payment instrument such as BABs (bonds need to be stripped of their coupons)
What are sport interest rates and how would we classify them in terms of ‘n’?
Current rate of interest- can refer to spot rates as oRn
What is a forward interest rate? How would we classify them in terms of ‘n’?
Commences at a future date and extends for a specified term- can refer to forward as 1Rn
What is the formula for converting spot rates to forward rates?
1r2= (F2/F1)-1
Where F2 and F1 are the future values
What is the formula for converting forward rates back to spot rates
0r2= (0r1+1r2)/ 2
What are the two yield curve theories?
1) Unbiased expectations theory
2) Liquidity premium theory
What does the unbiased expectations theory suggest?
Expectations of future sport rates determine forward rates and so decide the yield curve’s slope
What does the unbiased expectations theory say about normal and inverse yield curves
A normal yield curve= will occur when the market expects spot rates will rise in the future
An inverse yield curve will occur where the market expects the spot rates to fall in the future
What does the unbiased expectations theory assume and what does it ignore that the liquidity premium theory does not?
It assumes borrwers and lenders are unbiased in the choice between securities with different terms
IGNORES= transaction costs and price risk
What is the liquidity premium theory?
Theory that argues that market interest rates include risk premiums that are:
1) Higher for long term rates
2) May be expected to change
What is price risk? What does the liquidity theory say about price risk?
Price risk- the risk of a loss from adverse movement in interest rates
- Liquidity premium says choice between investment strategies is based on price risk
- Yield for longer term investments will include a risk premium to compensate investors for their price (liquidity) risk
What is the flaw of the liquidity premium theory?
Does not explain non- normal yield curves
