Principal = $10,000 ; Repay = $15,000 ; Interest = $5,000!! 10 years —> $5,000/10 = 5% per year!!Present value!Yield to maturity!-interest rate that requires price of an asset today with the present value of all future payments associated with that asset!YTM is the interest rate (i) that equates the 2 sides of the equations!!4 credit market instruments!1. simple loan - commercial bank loan!2. discount bond - US T-bill, zero coupon bond!3. coupon bond - U.S. Treasury Bond, corporate bond!4. fixed payment loan - car loan, mortgage!!Simple loan!-borrower receives principal and repays principal plus interest at maturity!!YTM on a simple loan = interest rate!Discount bond!-borrower repays face value of bond at maturity, but initially receives less than face value!Coupon bond!-borrower initially receives face value of bond, then makes payments of interest at regular intervals and repays face value at maturity!** if coupon issued at Par(face value) then coupon rate = YTM **!!!!Fixed payment loan!-borrower makes regular period payments of equal size. Each payment includes both principal and interest!Calculating YTM!** bond prices and interest rates are negatively related **!!YTM vs. ROR!-if bond is held until it matures, then ROR = YTM!!For a bond held t to t+1!!!!!If bond is held to maturity, then ROR always equals YTM!** if interest rate goes up, then price of bond goes down **!** longer term bonds are affected more by change in interest rates **!** long term bonds = higher interest rate risk **!** if interest rate goes up tomorrow, buy long term today**!** if interest rate goes down tomorrow, buy short term today **!!Real vs. nominal interest rates!-real interest rate = nominal minus rate of inflation!!Ex post vs ex ante real interest rates!-ex post = nominal minus actual rate of inflation (for the past)!-ex ante = nominal minus expected inflation rate (to predict future real interest rate)#Ch. 4 - Behavior of Interest Rates!!2 approaches to determination of interest rates!! 1. bond market framework!! 2. liquidity preference framework!!*both rely on theory of asset demand*!!Theory of asset demand!-other things equal, how will change in any of the following affect one’s decision to buy particular asset!-wealth!-asset’s expected return relative to other assets!-asset’s risk relative to other assets!-asset’s liquidity relative to other assets!!Demand for asset X will increase, other things equal, as result of:!-increase in wealth of buyers!-increase in expected return of asset x relative to expected return on other assets!-a decrease in riskiness of asset x relative to riskiness of other assets!-increase in liquidity of asset x relative to liquidity of other assets!!A model: market for bonds!-assume only type of kind and only one interest rate in the economy!!!Bond supply!-positive relationship between bond prices and quantity of bonds supplied!!Equilibrium!-quantity supplied = quantity demanded at the going price —>!!!!Factors that increase demand for bonds!-increase in wealth!-decrease in expected future interest rates!-***if expected future interest rates fall, expected future bond price will rise***!-decrease in expected future inflation!-decrease in riskiness of bond relative to
