PV of $250 paid in 2 years, i=15% PV = 250 / (1 + .15) ^ 2 = $189.04 Credit Market Instruments 1 – Simple Loan 2 – Fixed-Payment Loan 3 – Coupon Bond 4 – Discount Bond Simple Loan Lender provides borrower funds, borrower repays at maturity date plus additional interest amount $500 loan with 10% interest: 1 year: $500 * (1 + 0.10) = $550 2 years: $550 * (1 + 0.10) = $605 P = F (1 + i) ^ t P = Total payment F = Face Value i = interest rate t = number of periods Coupon Bond Face value amount is paid to issuer for ownership of bond, then issuer pays owner of bond fixed interest payment every period until maturity, then pays face value to owner Three pieces of information: Issuer of bond, maturity date of bond, coupon rate of bond Coupon Bond P = C * (1 – (1 / (1 + i) ^ t)) / r + F / (1 + i) ^ t P = bond price C = Coupon rate i = interest rate t = number of periods F = face value Ex. $1000, 5% coupon, annual bond with 15 year maturity. What would the price be if the interest rate was 6.5%? A. $858.96 Discount Bond Like a coupon bond, but without coupons No interest payments, is issued at a discount of face value Ex. Face value of $1000 may be bought for $900 and in one years time the owner will be paid $1000 Examples include Canadian government treasury bills and long term zero-coupon bonds Discount Bond Similar formula as Coupon Bond, just missing the coupon section: P = F / (1 + i) ^ t P = price of bond F = face value i = interest rate t = number of periods $10,000, zero-coupon bond maturing in 7 years, interest rate is 4%. Selling price? A. $7,599.18 Fixed Payment Loan Lender provides borrower funds, borrower pays back lender in fixed payments every period until the loan is paid off (ie. Mortgage or auto loan) http://www.tdcanadatrust.com/mortgag es/ Subprime Loans “A mortgage granted to a borrower considered subprime, that is, a person with a less-than-perfect credit report. Subprime borrowers have either missed payments on a debt or have been late with payments. Lenders charge a higher interest rate to compensate for potential losses from customers who may run into trouble or default.” Subprime Meltdown Background: U.S. housing bubble began in early 2000’s Low interest rates and new “mania” for buying houses caused housing prices to skyrocket Some banks and newly-formed lending institutions took advantage of the situation by offering long term mortgages to people who could normally not afford them – subprime borrowers These borrowers relied on the capital value of their new homes to pay off the mortgage, rather than their earning power Subprime Meltdown Outcome The rapid rise in housing prices created a bubble, which burst in late 2005 Housing prices began to fall and, eventually, many subprime borrowers began to default on their loans This caused the collapse and bankruptcy of many of these institutions, and has hurt the financial industry substantially Subprime Meltdown Subprime Meltdown Outcome This meltdown has depressed the US economy, causing the Federal Reserve to lower it’s benchmark rate Has caused a weakening of the US dollar, and billions of dollars of losses for investment funds Subprime Meltdown International All of this has caused Canada to be affected as well Canadian dollar has risen against US dollar and is now at parity Depressed US housing market and high dollar has resulted in a crisis for the forestry industry (ie. Canfor mill closures) Subprime Meltdown Initially, it was all caused by extremely low interest rates in the early 2000’s in order to stimulate the economy after the dot-com crash Measuring Interest Rates Yield to Maturity Current Yield Yield on a Discount Basis Yield to Maturity Interest rate that equates PV of cash flow payments received with its value today Most accurate measure of interest rates 1. Simple Loans 2. Fixed-Payment Loans 3. Coupon Bonds 4. Perpetuity 5. Discount Bonds Yield to Maturity Simple Loans Q. Pete borrows $100 from Bob and Bob wants back $110 from him next year. YTM? A. PV = FV / ( 1 + i ) ^ t 100 = 110 / (1+ i ) ^ 1 r = 0.1 = 10% In a simple loan, i = YTM Yield to Maturity Fixed Payment Loan Q. $100,000 loan, payments of $9439.29 for next 20 years. YTM? LV = FP / (1 + i) + FP / (1 + i)^2 + ... + FP / (1 + i) ^ n LV = Loan Value FP = Fixed Yearly Payment n = number of years until maturity A. 0.7 = 7% Yield to Maturity Coupon Bond PP = C ((1-(1/(1+i)^n)/i) + FV/ (1+i)^n PP = Value of Bond C = Coupon Payment i = YTM N = number of periods FV = Face value of bond YTM Price of 8% coupon bond is $1122, FV of $1000, 12 years to maturity, paid annually, what is YTM? PP = C ((1-(1/(1+i)^n)/i) + FV/ (1+i)^n PP = Value of Bond C = Coupon Payment i = YTM N = number of periods FV = Face value of bond A. 0.65 = 6.5% Yield to Maturity Perpetuity Coupon bond with no maturity date (goes on forever) P=C/i P = Price of perpetuity C = Yearly Payment i = YTM Q. Bond with price of $2000 and pays $100 annually forever, what is YTM? Answer: 100 / 2000 = 0.05 = 5% Yield to Maturity Discount Bond i = (F – P) / P F = Face Value P = Current Price Ex. Treasury Bills that pays a FV of $1000 in 1 year. Purchase Price is $900. YTM? A. i = (1000 – 900) / 900 = 0.111 = 11.1% Yield to Maturity Yield to Maturity for bonds is the actual interest rate Bond prices and interest rates are negatively related Current Yield Yield of a bond at a point in time Does not reflect total return Used as approximation to describe interest rates for long term bonds CY = C / P C = Coupon payment P = Current price Current Yield Q. What is the current yield of a $1000, 8% coupon bond maturing in 3 years and selling for a price of $1200? A. CY = C / P = 80 / 1200 = 0.0666 = 6.66% Yield on a Discount Basis Most accurate measure of interest rates for short term bonds Yield of bills with a maturity of less than one year i = (F – P) / P * 365 / Days to Maturity i = Yield on a discount basis F = Face Value P = Purchase Price Yield on a Discount Basis Q. 91 day treasury bill selling for $988 with FV of $1000 A. i = (F – P) / P * 365 / Days to Maturity i = (1000 – 988) / 988 * 365 / 91 = 0.0487 = 4.87% Central Banks and Interest Rates Very important in determining interest rates Central banks determine lending rates and heavily influence market interest rates Lending rate is the rate that the central bank will lend to other banks, thereby insuring that all lending rates (inter-bank or otherwise) are above this rate Central Banks Can be government controlled, or independent of government (Bank of Canada, Federal Reserve) Determine countries monetary policy Sole issuer of the countries' currency Supervises banking industry “Lender of last resort” and governments banker Manages gold reserves Sets interest rate International Interest Rates Canada United States United Kingdom Europe Japan Australia China India - 4.5% 4.75% 5.75% 4.0% 0.5% 6.5% 7.02% 7.75% Canada Determined by the Bank of Canada United States Determined by the Federal Reserve United Kingdom Determined by the Bank of England 2006 2004 2002 2000 1998 1996 1994 1992 1990 1988 1986 1984 1982 1980 Interest Rate Japan Determined by Bank of Japan Japan Interest Rates 10 9 8 7 6 5 4 3 2 1 0 Japan Island nation with no natural resources and very high population, and yet has the second largest economy in the world with the highest life expectancy, and very technologically advanced For past 15 years has been in prolonged stagnation due to many factors Japan As a result, the interest rate has been very low (0.1% for past 5 years) in order to stimulate the economy Extremely low compared to Canada (4.5%) Low interest rate has resulted in negative inflation Interest Rates vs Returns Rate of return on a bond not necessarily the yield to maturity of the bond Rate of return is dependant on behaviour of market interest rates over the holding period of the bond If a bond is held for its entire life, then yield to maturity is equal to the return of the bond RET = (C / Pt) + (Pt+1 – Pt) / Pt RET = Return Pt = Initial Price of Bond Pt+1 = Selling Price of Bond C = Coupon Payment Interest Rates vs Returns Q. What is the rate of return on a bond bought for $988 and sold one year later for $1200? The coupon rate is 5%, and face value is $1000. A. (C / Pt) + (Pt+1 – Pt) / Pt = ( 50 / 988) + (1200 – 988) / 988 = 0.0506 + 0.2146 = 0.2652 = 26.5% Volatility of Bonds Longer term = larger risk/more volatility Known as interest rate risk Real vs Nominal Rates So far, i = nominal interest rate Real interest rate is a more accurate rate that is adjusted for inflation i = real interest rate + expected inflation OR Real interest rate = i – expected inflation i = nominal rate Actual inflation is not known until later Real vs Nominal Rates When real interest rate is low, there are greater incentives to borrow and fewer to lend Measured by indexed bonds Interest and principal payments are adjusted for price levels by indexing to the Consumer Price Index (CPI) Real vs Nominal Rates Real rate is lower than nominal rate because of inflation Learning Objectives 1.
