7、. Corporate bonds Municipal bonds General obligation bonds (Gos) and revenue bonds Taxes: in the past munis interest income was not subject to federal and state income taxes. However, the Tax Reform Act of 1986 reduced this advantage by eliminating interest expense deductions on borrowed funds used
8、to purchase munis. Note that 80% of interest expenses can be deducted if funds are used to purchase local government munis with no more than $10 million of new issues in any one year (i.e., so-called “bank qualified” munis).,Types of investment securities,Tax formula for munis: YTMm/(1-T) - (1.0 x A
9、verage cost of funds x T)/(1-T) = YTMTE where T = bank tax rate, the factor 1.0 is for 100% of interest expenses are not deductible from taxes (i.e., 0.20 for bank qualified munis), and average cost of funds is based on IRS rules, and YTMTE = a tax equivalent yield for comparison to taxable bonds.Ex
10、ample: given T = 0.34, 1.0 is used, average cost of fund = 7%, and YTMm= 8%, we have0.08/(1 - 0.34) - (1.0 x 0.07 x 0.34)/1 - 0.34) = 0.0852 or 8.52%,Evaluating investment risk,Security-specific risk Default risk and credit ratings by Moodys and Standard and Poors agencies: Investment grade bonds (t

12、ent risk,Evaluating investment risk,Security-specific risk Price risk related to changes in interest rates: P = -D x B x i/(1 + i) where = change, D = duration, B = price of bond before change in interest rates, and i = interest rate.Example: given a $1,000 bond with a 5-year duration and an expecte
13、d increase in interest rates from 5% to 7%, we haveP = -5 x $1,000 x (0.02/1.05) = $95New price of this bond is $905. Notes: High coupon bonds have shorter durations than low coupon bonds and, therefore, lower price risk, all else the same. Duration analysis can be used to “immunize” the investment
14、portfolio from the opposing forces of price risk and reinvestment risk.,Evaluating investment risk,Security-spccific risk Yield curve and changes in its level and shape over the business cycle. Expectations theory of the yield curve:(1 + 0R2)2 = (1 + 0R1) (1 + 1r2)where 0R2 = the 2-year (spot) rate,
15、 0R1 =the 1-year (spot) rate, and 1r2 = the 1-year (future implicit) rate.Example: given 0R2 = 10% and 0R1 = 9%, we have(1 + .10)2 = (1 + .09) (1 + 1r2)(1 + 1r2) = 1.11 such that 1r2 = 0.11 or 11%Notes:Assumes that investors are risk-neutral and seek to maximize returns.Empirical studies have found
16、that implicit future rates are biased upward.,Evaluating investment risk,Security-spccific risk Liquidity premium theory: Long-term interest rates contain a premium for price risk. Need to subtract this premium from long-term rates to adjust the expectations formula and get unbiased estimated of imp
17、licit future rates(e.g., if the liquidity premium equals 0.5%, and 0R2 = 10%, then use0R2 =9.5% is the formula for the expectations theory). Segmented markets theory Money and capital markets are separate in many ways with different supply and demand factors affecting changes in interest rates in th
18、ese markets. Preferred-habitat theory Takes into account all three yield curve theories.,Evaluating investment risk,Security-spccific risk Value-at-risk (VAR) The maximum amount that could be lost in investment activities in a specified period of time. Example: based on an historical distribution of
19、 interest rates, the probability of a 50 basis point increase in interest rates in a 10-day holding period is 5%. If a bank held $1 billion of securities with average duration of 3 years, and interest rates are currently 6%, the maximum possible loss in one-out-of-20 holding periods isP = -3 x $1bil
20、lion x (0.0050/1.06) = -$15.6 million Note: Banks need to calculate VAR under alternative conditions about interest rate forecasts. These stress tests consider the sensitivity of VAR to different assumptions about interest rates. Also, bank management can use derivatives securities to hedge rate mov
21、ements and thereby better control large VARs.,Evaluating investment risk,Security-specific risk Marketability risk Selling securities quickly without capital loss. Call risk Bonds that can be redeemed by the borrowing firm prior to maturity. Call deferment period must expire. Also, bonds price must
22、be greater than or equal to the call price. Call risk related to reinvestment risk, as bonds are typically called during low interest rate periods. Call premium paid as compensation for reinvestment risk.,Evaluating investment risk,Portfolio risk Diversification reduces the variability of returns on
23、 assets. Securities can reduce portfolio risk when combined with loans (e.g., loan losses during a recession and associated low interest rates can be partially offset with increasing capital gains on securities as rates declined). Inflation risk Unanticipated increases in inflation can cause losses
24、in the securities portfolio. Historic lows in inflation rates in the 1990s has been cited as a factor in explaining the strong capital gains in securities markets (especially the stock market).,Investment strategies,Passive investment strategies Space-maturity approach (or ladder approach) Spread av

Simple and low transactions costs, but passive with respect to interest rate conditions and liquidity is sacrificed to some extent. Split-maturity approach (or barbell approach) Greater quantiti

Example: purchase short-term securities when interest rate levels are low and sw
28、itch to long-term securities when rates are high. As rates subsequently fall, earn a capital gain on long-term securities. Also, when rates were rising, capital losses are avoided. Riding the yield curve - assumes that the yield curve will not move in the near future. Example: assume that the yield
29、curve is upward sloped. Buy securities and hold them so that their maturity decreases and (due to the shape of the yield curve) their yields decline (prices rise). Sell for a capital gain.Yh = Y0 + Tr(Y0 + Ym)/ TrExample: given the original yield on a bond is 10%, time remaining to maturity on the b

33、ium. Yield-pickup, or coupon, swap - exchange low-coupon for high-coupon bonds, or vice versa, due to interest rate and taxdifferences between these two types of bonds. Spread, or quality, swap - exchange of two bonds with unequal risk. Motivated by an abnormally low or high price of either or both bonds. Portfolio shift - sell low yielding securities and replace with high yielding securities. Deduct capital losses on low yielding securities from taxes. Key is to compare net profits on these two bond strategies over time and choose higher profit strategy.,
