City Bank issued $200 million of one-year CDs in the United States at a rate of 6.50 percent. It
invested part of this money, $100 million, in the purchase of a one-year bond issued by a U.S. firm
at an annual rate of 7 percent. The remaining $100 million was invested in a one-year Brazilian
government bond paying an annual interest rate of 8 percent. The exchange rate at the time of
the transaction was Brazilian real 1/$.

Consideration should be given to the fact that the Brazilian bond was for Real100 million. Thus, at
maturity the bond will be paid back for Real100 million/1.20 = $83,333,333.33. Therefore, the
strengthening dollar will have caused a loss in capital ($16,666,666.67) that far exceeds the

Sun Bank USA purchased a 16 million one-year euro loan that pays 12 percent interest annually.
The spot rate of U.S. dollars per euro is 1.40. Sun Bank has funded this loan by accepting a British
pound-denominated deposit for the equivalent amount and maturity at an annual rate of 10
percent. The current spot rate of U.S. dollars per British pound is 1.60.
a. What is the net interest income earned in dollars on this one-year transaction if the spot
rates of U.S. dollars per euro and U.S. dollars per British pound at the end of the year

b. What should be the spot rate of U.S. dollars per British pound at the end of the year in order
for the bank to earn a net interest margin of 4 percent?
A net interest margin of 4 percent would imply $22,400,000 x 0.04 = $896,000.
The net cost of deposits should be $2,880,000 - 896,000 = $1,984,000.
Pound rate = $1,984,000/£1,400,000 = $1.4171/£.
Thus, the pound should be selling at $1.4171/£ in order for the bank to earn 4 percent.

What are the two primary methods of hedging FX risk for an FI? What two conditions are
necessary to achieve a perfect hedge through on-balance-sheet hedging? What are the
advantages and disadvantages of off-balance-sheet hedging in comparison to on-balance-sheet
hedging?
The manager of an FI can hedge using on-balance-sheet techniques or off-balance-sheet techniques. Onbalance-sheet hedging requires matching currency positions and durations of assets and liabilities. If the
duration of foreign-currency-denominated fixed rate assets is greater than similar currency
6
FIN 683
Professor Robert Hauswald
Financial-Institutions Management
Kogod School of Business, AU
denominated fixed rate liabilities, the market value of the assets could decline more than the liabilities
when market rates rise and therefore the hedge will not be perfect. Thus, in matching foreign currency
assets and liabilities, not only do they have to be of the same currency, but also of the same duration in
order to have a perfect hedge.
Advantages of off-balance-sheet FX hedging:
The use of off-balance-sheet hedging devices, such as forward contracts, enables an FI to reduce or
eliminate its FX risk exposure without forfeiting potentially lucrative transactions. On-balance-sheet
transactions result in immediate cash flows, whereas off-balance-sheet transactions result in contingent
future cash flows. Therefore, the up-front cost of hedging using off-balance-sheet instruments is lower
than the cost of on-balance-sheet transactions. Moreover, since on-balance-sheet transactions are fully
reflected in financial statements, there may be additional disclosure costs to hedging on the balance
sheet.
Off-balance-sheet hedging instruments have been developed for many types of risk exposures. For
currency risk, forward contracts are available for the majority of currencies at a variety of delivery dates.
Moreover, since the forward contract is negotiated over the counter, the counterparties have maximum
flexibility to set terms and conditions.
Disadvantages of off-balance-sheet FX hedging:
There is some credit risk associated with off-balance-sheet hedging instruments since there is some
possibility that the counterparty will default on its obligations. This credit risk exposure is exacerbated in
negotiated markets such as the forward market, but mitigated for exchange-traded hedging instruments
such as futures contracts.

North Bank has been borrowing in the U.S. markets and lending abroad, thus incurring foreign
exchange risk. In a recent transaction, it issued a one-year, $2 million CD at 6 percent and funded
a loan in euros at 8 percent. The spot rate for the euro was €1.45/$1 at the time of the
transaction.
a. Information received immediately after the transaction closing indicated that the euro
will change to €1.47/$1 by year-end. If the information is correct, what will be the
realized spread on the loan inclusive of principal? What should have been the bank
interest rate on the loan to maintain the 2 percent spread?
Amount of loan in € = $2 million x 1.45 = €2.9 million.
Interest and principal at year-end = €2.9m x 1.08 = €3.132m/1.47 = $2,130,612.24
Interest and principal of CDs = $2m x 1.06 = $2,120,000
Net interest income = $2,130,612.24 – $2,120,000 = $10,612.24
Net interest margin = $10,612.24/2,000,000 = 0.0053 or 0.53 percent.
In order to maintain a 2 percent spread, the interest and principal earned at €1.47/$ should be:
€2.9m.(1 + x)/1.47 = $2.16m. (Because ($2.16m. - $2.12m.)/$2.00m. = 0.02, or 2%).
Therefore, (1 + x) = ($2.16m. x 1.47)/ €2.9m. = 1.0949, and x = 0.0949 or 9.49 percent,
or the bank should have charged a rate of 9.49 percent on the loan.
b. The bank had an opportunity to sell one-year forward euros at €1.46/$. What would
have been the spread on the loan if the bank had hedged forward its foreign exchange
exposure?
Net interest income if hedged
= €2.9m. x 1.08 = €3.132m./1.46 = $2.1452m. - $2.12m.
= $0.0252 million, or $25,205.48
Net interest margin = $0.0252m./$2m. = 0.0126, or 1.26 percent
c. What would have been an appropriate change in loan rates to maintain the 2 percent
spread if the bank intended to hedge its exposure using the forward contracts?
To maintain a 2 percent spread: €2.9m.(1 + x)/1.46 = $2.16m. => x = 8.74 percent

Suppose that the current spot exchange rate of U.S. dollars for Australian dollars, SUS$/A$,
is .7590 (i.e., 0.759 dollars, or 75.9 cents, can be received for 1 Australian dollar). The
price of Australian-produced goods increases by 5 percent (i.e., inflation in Australia, IPA, is 5
percent), and the U.S. price index increases by 3 percent (i.e., inflation in the United States, IPUS,
is 3 percent). Calculate the new spot exchange rate of U.S. dollars for Australian dollars that
should result from the differences in inflation rates.
According to PPP, the 5 percent rise in the price of Australian goods relative to the 3 percent rise in the
price of U.S. goods results in a depreciation of the Australian dollar (by 2 percent). Specifically, the
exchange rate of Australian dollars to U.S. dollars should fall, so that:
iUS - iA = ΔSUS$/A$/SUS$/A$
Plugging in the inflation and exchange rates, we get:
.03 - .05 = ΔSUS$/A$/SUS$/A$ = ΔSUS$/A$/ .759
or:
-.02 = ΔSUS$/A$/.759
and:
ΔSUS$/A$ = -(.02) × .759 = -.01518
Thus, it costs 1.518 cents less to receive an Australian dollar (or it costs 15.98 cents (75.9 cents - 1.518
cents), or .74382 of $1, can be received for 1 Australian dollar). The Australian dollar depreciates in
value by 2 percent against the U.S. dollar as a result of its higher inflation rate.

What is the expected spread?
Borrow $1,000,000 in U.S. by issuing CDs
⇒ Interest and principal at year-end = $1,000,000 x 1.08 = $1,080,000
Make a loan in Japan
⇒ Interest and principal = $1,000,000/0.60 = ¥1,666.667 x 1.04 = ¥1,733,333
Purchase U.S. dollars at the forward rate of $0.64 x 1,733,333 = $1,109,333.33
Spread = $1,109,333.33 - $1,080,000 = $29,333.33/1,000,000 = 2.93%
b. What forward rate will prevent an arbitrage opportunity?
The forward rate that will prevent any arbitrage is given by solving the following equation:
Ft =

An FI has $100,000 of net positions outstanding in British pounds (£) and -$30,000 in Swiss francs
(SF). The standard deviation of the net positions as a result of exchange rate changes is 1 percent
for the SF and 1.3 percent for the £. The correlation coefficient between the changes in exchange
rates of the £ and the SF is 0.80.
a. What is the risk exposure to the FI of fluctuations in the £/$ rate?
Since the FI has a positive £ position, an appreciation of the £ will increase the value of its £denominated assets more than its liabilities, providing a net gain. The opposite will occur if the £
depreciates.
b. What is the risk exposure to the FI of fluctuations in the SF/$ rate?
Since the FI has a negative net position in SFs, the value of its Swiss-denominated assets will
increase in value, but not as much as the value of its liabilities. Hence, an appreciation of the SF
will lead to a net loss. The opposite will occur if the currency depreciates.
c. What is the risk exposure if both the £ and the SF positions are aggregated?
Use the DEAR formula for a portfolio:

What are the differences between a microhedge and a macrohedge for a FI? Why is it
generally more efficient for FIs to employ a macrohedge than a series of microhedges?
14
FIN 683
Professor Robert Hauswald
Financial-Institutions Management

A microhedge uses a derivative contract such as a forward or futures contract to hedge the risk
exposure of a specific transaction, while a macrohedge is a hedge of the duration gap of the entire
balance sheet. FIs that attempt to manage their risk exposure by hedging each balance sheet position
will find that hedging is excessively costly, because the use of a series of microhedges ignores the FI’s
internal hedges that are already on the balance sheet. That is, if a long-term fixed-rate asset position is
exposed to interest rate increases, there may be a matching long-term fixed-rate liability position that
also is exposed to interest rate decreases. Putting on two microhedges to reduce the risk exposures of
each of these positions fails to recognize that the FI has already hedged much of its risk by taking
matched balance sheet positions. The efficiency of the macrohedge is that it focuses only on those
mismatched positions that are candidates for off-balance-sheet hedging activities.

Solving for the impact on the change in equity under this assumption involves finding the
impact of the change in interest rates on each side of the balance sheet, and then
determining the difference in these values. The analysis is based on the equation:
Expected ∆E = ∆A - ∆L
∆A = -DA[∆RA/(1 + RA)]A = -6[0.01/1.10]$150m = -$8.1818 million
and ∆L = -DL[∆RL/(1 + RL)]L = -4[0.01/1.06]$135m = -$5.0943 million

a. Should the bank go short or long on the futures contracts to establish the correct
macrohedge?
The bank should sell futures contracts since an increase in interest rates would cause the
value of the equity and the futures contracts to decrease. But the bank could buy back the
futures contracts to realize a gain to offset the decreased value of the equity.
b. How many contracts are necessary to fully hedge the bank?
If the market value of the underlying 20-year, 8 percent benchmark bond is $95 per $100, the
market rate is 8.5295 percent (using a calculator) and the duration is 10.3725 as shown on the last
page of this chapter solutions. The number of contracts to hedge the bank is:

c. Verify that the change in the futures position will offset the change in the cash balance sheet
position for a change in market interest rates of plus 100 basis points and minus 50 basis
points.
For an increase in rates of 100 basis points, the change in the cash balance sheet position is:
Expected ∆E = -DGAP[∆R/(1 + R)]A = -2.4(0.01/1.10)$150m = -$3,272,727.27. The change in bond
value = -10.3725(0.01/1.085295)$95,000 = -$9,079.41, and the change in 365 contracts is $9,079.41 x -365 = $3,313,986.25. Since the futures contracts were sold, they could be
repurchased for a gain of $3,313,986.25. The sum of the two values is a net gain of $41,258.98.
For a decrease in rates of 50 basis points, the change in the cash balance sheet position is:
Expected ∆E = -DGAP[∆R/(1 + R)]A = -2.4(-0.005/1.10)$150m = $1,636,363.64. The
change in each bond value = -10.37255(-0.005/1.085295)$95,000 = $4,539.71 and the
change in 365 contracts is $4,539.71 x -365 = -$1,656,993.13. Since the futures contracts

d. If the bank had hedged with Treasury bill futures contracts that had a market value of $98 per

In cases where a large number of Treasury bonds are necessary to hedge the balance sheet
with a macrohedge, the FI may need to consider whether a sufficient number of deliverable
Treasury bonds are available. The number of Treasury bill contracts necessary to hedge the
balance sheet is greater than the number of Treasury bonds, the bill market is much deeper
and the availability of sufficient deliverable securities should be less of a problem.
17.
Reconsider Tree Row Bank in problem 16 but assume that the cost rate on the liabilities is
6 percent.
a. How many contracts are necessary to fully hedge the bank?
In this case, the bank faces different average interest rates on both sides of the balance
sheet. Further, the yield on the bonds underlying the futures contracts is a third interest rate.
Thus, the hedge also has the effects of basis risk. Determining the number of futures
contracts necessary to hedge this balance sheet must consider separately the effect of a
change in rates on each side of the balance sheet, and then consider the combined effect on
equity. Estimating the number of contracts can be determined with the modified general
equation shown on the next page.
b. Verify that the change in the futures position will offset the change in the cash balance sheet
position for a change in market interest rates of plus 100 basis points and minus 50 basis
points.
For an increase in rates of 100 basis points, ∆E = 0.01[(4/1.06)$135 m – (6/1.10)$150 m] = $3,087,478.56. The change in the bond value is –10.3725(.01/1.085295)$95,000 = -$9,079.41, and the
change for -340 contracts = $3,087,000.89. The sum of the two values is a net gain of $477.67.
For a decrease in rates of 50 basis points, ∆E = -0.005[(4/1.06)$135 m – (6/1.10)$150 m] =
$1,543,739.28. The change in the bond value is –10.3725(-.005/1.085295)$95,000 =
$4,539.71, and the change for -340 contracts = -$1,543,500.45. The sum of the two values
is a net loss of $238.83.

c. If the bank had hedged with Treasury bill futures contracts that had a market value of $98 per
$100 of face value (implying a discount rate of 8 percent), how many futures contracts would
have been necessary to fully hedge the balance sheet?
A market value of $98 per $100 of face value implies a discount rate of 8 percent on the
underlying T-bills. Therefore, the equation developed above in part (a) to determine the number
of contracts necessary to hedge the bank can be adjusted as follows for the use of T-bill contracts:

How would your answer for part (b) in problem 16 change if the relationship of the price
sensitivity of futures contracts to the price sensitivity of underlying bonds were br = 0.92?
The number of contracts necessary to hedge the bank would increase to 397 contracts. This can be
found by dividing $360,000,000 by (10.3725 x $95,000 x 0.92).

b. What is the FI's interest rate risk exposure?
The FI is exposed to interest rate increases. The market value of equity will decrease if
interest rates increase.
c. How can the FI use futures and forward contracts to put on a macrohedge?
The FI can hedge its interest rate risk by selling future or forward contracts.
d. What is the impact on the FI's equity value if the relative change in interest rates is an
increase of 1 percent? That is, ∆R/(1+R) = 0.01.
∆E = - 8.19(950,000)(.01) = -$77,800
e. Suppose that the FI in part (c) macrohedges using Treasury bond futures that are currently
priced at 96. What is the impact on the FI's futures position if the relative change in all interest
rates is an increase of 1 percent? That is, ∆R/(1+R) = 0.01. Assume that the deliverable
Treasury bond has a duration of nine years.
∆E = - 9(96,000)(.01) = -$8,640 per futures contract. Since the macrohedge is a short hedge, this
will be a profit of $8,640 per contract.
f.
If the FI wants to macrohedge, how many Treasury bond futures contracts does it need?
To macrohedge, the Treasury bond futures position should yield a profit equal to the loss in equity
value (for any given increase in interest rates). Thus, the number of futures contracts must be
sufficient to offset the $77,800 loss in equity value. This will necessitate the sale of $77,800/8,640
= 9.005 contracts. Rounding down, to construct a macrohedge requires the FI to sell 9 Treasury
bond futures contracts.

Refer again to problem 21. How does consideration of basis risk change your answers to problem
21?
23
FIN 683
Professor Robert Hauswald
Financial-Institutions Management
Kogod School of Business, AU
In problem 21, we assumed that basis risk did not exist. That allowed us to assert that the percentage
change in interest rates (∆R/(1+R)) would be the same for both the futures and the underlying cash
positions. If there is basis risk, then (∆R/(1+R)) is not necessarily equal to (∆Rf/(1+Rf)). If the FI wants to
fully hedge its interest rate risk exposure in an environment with basis risk, the required number of
futures contracts must reflect the disparity in volatilities between the futures and cash markets.
a. Compute the number of futures contracts required to construct a macrohedge if
[∆Rf/(1+Rf) / ∆R/(1+R)] = br = 0.90
If br = 0.9, then: N f =
− ( D A - k D L ) A − 8.19(950,000)
=
= − 10 contracts
(9)(96,000)(.90)
D F P F br
b. Explain what is meant by br = 0.90.
br = 0.90 means that the implied rate on the deliverable bond in the futures market moves by 0.9
percent for every 1 percent change in discounted spot rates (∆R/(1+R)).
c. If br = 0.90, what information does this provide on the number of futures contracts needed to
construct a macrohedge?
If br = 0.9 then the percentage change in cash market rates exceeds the percentage change in
futures market rates. Since futures prices are less sensitive to interest rate shocks than cash
prices, the FI must use more futures contracts to generate sufficient cash flows to offset the cash
flows on its balance sheet position.

An insurance company owns $50 million of floating-rate bonds yielding LIBOR plus 1 percent.
These loans are financed with $50 million of fixed-rate guaranteed investment contracts (GICs)
costing 10 percent. A finance company has $50 million of auto loans with a fixed rate of 14
percent. The loans are financed with $50 million of CDs at a variable rate of LIBOR plus 4 percent.
a. What is the risk exposure of the insurance company?
The insurance company (IC) is exposed to falling interest rates on the asset side of the balance
sheet.
b. What is the risk exposure of the finance company?
The finance company (FC) is exposed to rising interest rates on the liability side of the balance
sheet.
c. What would be the cash flow goals of each company if they were to enter into a swap
arrangement?
The IC wishes to convert the fixed-rate liabilities into variable-rate liabilities by swapping the fixedrate payments for variable-rate payments. The FC wishes to convert variable-rate liabilities into
fixed-rate liabilities by swapping the variable-rate payments for fixed-rate payments.
d. Which FI would be the buyer and which FI would be the seller in the swap?
The FC will make fixed-rate payments and therefore is the buyer in the swap. The IC will make
variable-rate payments and therefore is the seller in the swap.

Please see the diagram at the top of the next page. Note that the fixed-rate swap payments from
the finance company to the insurance company will offset the payments on the fixed-rate
liabilities that the insurance company has incurred. The reverse situation occurs regarding the
variable-rate swap payments from the insurance company to the finance company. Depending on
the rates negotiated and the maturities of the assets and liabilities, both FIs now have durations
much closer to zero on this portion of their respective balance sheets.

What are reasonable cash flow amounts, or relative interest rates, for each of the payment
streams?
Determining a set of reasonable interest rates involves an analysis of the benefits to each FI. That
is, does each FI pay lower interest rates with the swap than contractually obligated without the
swap? Clearly, the direction of the cash flows will help reduce interest rate risk.
One feasible swap is for the IC to pay the FC LIBOR + 2.5 percent, and for the FC to pay the IC 12
percent. The net financing cost for each firm is given below.

A commercial bank has $200 million of floating-rate loans yielding the T-bill rate plus 2 percent.
These loans are financed with $200 million of fixed-rate deposits costing 9 percent. A savings bank

of CDs with a variable rate of the T-bill rate plus 3 percent.
a. Discuss the type of interest rate risk each FI faces.
The commercial bank is exposed to a decrease in rates that would lower interest income, while
the savings bank is exposed to an increase in rates that would increase interest expense. In either
case, profit performance would suffer.
b. Propose a swap that would result in each FI having the same type of asset and liability cash

b. Where is the comparative advantage of the two banks?
Bank 1 has a comparative advantage in the fixed-rate market because the difference in fixed rates
is 2 percent in favor of Bank 1. Bank 2 has the comparative advantage in the variable-rate market
because the difference in variable rates is only –1 percent against Bank 1. One way to compare the
rate alternatives is to utilize the following matrix.

c. What is the quality spread in the fixed versus variable interest rates for the two FIs?
The quality spread is the difference between the fixed-rate versus variable-rate differential. Thus,
the net quality spread = -2% - (-1%) = -1 percent. This amount represents the net amount of gains
(interest savings) to be allocated between the firms.
d. What is an example of a feasible swap?
Many rate combinations are possible to achieve the quality spread or reduced interest charge. The
following is a framework to achieve the outside boundaries of acceptable interest rates using the
matrix of possible rates shown in part (b).

d. What factors will determine the final swap arrangement?
The primary factor that will determine the final distribution of the swap rates is the present value
of the cash flows for the two parties. The most important no-arbitrage condition is that the
present value of the expected cash flows made by the buyer should equal the present value of the
expected cash flows made by the seller. Secondary factors include the negotiating strengths of
either party to the transaction.

Two multinational FIs enter their respective debt markets to issue $100 million of two-year notes.
FI A can borrow at a fixed annual rate of 11 percent or a floating rate of LIBOR plus 50 basis points,
repriced at the end of the year. FI B can borrow at a fixed annual rate of 10 percent or a floating
rate of LIBOR, repriced at the end of the year.
a. If FI A is a positive duration gap insurance company and FI B is a money market mutual fund,
in what market(s) should each firm borrow so as to reduce its interest rate risk exposure?
FI A will prefer to borrow in the fixed-rate debt market in order to generate positive cash flows
when interest rates increase. This will offset the impact of an increase in interest rates, which
would cause the market value of the insurance company's equity to decline. FI B will prefer to
borrow in the floating rate debt market so as to better match the duration of its short-term assets.
b. In which debt market does FI A have a comparative advantage over FI B?
The matrix of possible interest rates is given below.

FI A has a comparative advantage in the floating-rate market and FI B has a comparative
advantage in the fixed-rate market. This is because the default risk premium of FI A over FI B is 50
basis points in the floating-rate market and 100 basis points in the fixed-rate market.
c. Although FI A is riskier than FI B and therefore must pay a higher rate in both the fixed-rate
and floating-rate markets, there are possible gains to trade. Set up a swap to exploit FI A's
comparative advantage over FI B. What are the total gains from the swap? Assume a swap
intermediary fee of 10 basis points.
The total gains to the swap are 50 basis points (the price differential on FI A's default risk premium
over FI B) less 10 basis points (the swap intermediary fee). Both FI A and B can exploit this price
differential by issuing debt in the debt market in which they have comparative advantage and
then swapping the interest payments. The 40 basis points can be allocated to either FI A and/or FI
B according to the terms of the swap.
A possible set of feasible swap rates that give all of the gains to FI A (see part (d) below) is
illustrated here.

FI A is paying the intermediary fee, since FI B is receiving no benefits from this swap transaction.
The 40 basis point net differential could be shared in a number of other combinations where FI A
received most (exploited) of the benefit.
d. The gains from the swap can be apportioned between FI A and FI B through negotiation. What
terms of swap would give all the gains to FI A? What terms of swap would give all the gains to
FI B?
All the gains go to FI A if FI B pays LIBOR for FI A's floating rate debt. Then FI A must pay 10
percent for FI B's fixed-rate debt plus 50 basis points on FI A's floating rate debt plus 10 basis
points for the swap intermediary's fee. The total fixed annual interest cost to FI A is 10.6 percent,
a savings of 40 basis points over the cash-market fixed rate of 11 percent. This swap rate
apportionment is illustrated in part (c) above.
All the gains go to FI B if FI A pays 11 percent for FI B’s fixed-rate, 10 percent debt. Then FI B pays
LIBOR plus 50 basis points on FI A's floating rate debt for a net savings of 50 basis points. The
savings occurs because FI B receives an excess 1 percent from FI A, but must pay 50 basis points
more to FI A than it would pay in the cash floating-rate market. FI A must pay 11 percent against FI
B's fixed-rate debt, but receives its exact liability payment from FI B. A diagram of this allocation is
given below.

e. Assume swap pricing that allocates all gains from the swap to FI A. If FI A buys the swap from
FI B and pays the swap intermediary's fee, what are the realized net cash flows if LIBOR is 8.25

This solution is an extension of the diagram in part (c) and the explanation at the beginning of part
(d) above where LIBOR is 8.25 percent. The summary shows the effective cost rate converted to
dollars for the total cash flows of each FI. However, the cash flows in a swap arrangement include
only the differential cash flows between the two parties. Thus, at the end of the year, FI A would
pay $1.75m ($10.00m - $8.25m) to FI B and $0.10m to the intermediary for a total cash flow on
the swap arrangement of $1.85m. FI B receives $1.75m from FI A.

If FI A buys the swap in part (e) from FI B and pays the swap intermediary's fee, what are the

Even though LIBOR has increased to 11 percent, FI A’s total effective cost rate has not changed.
The rate remains at 10.60 percent, or a total of $10.60 million. However, the cost rate for FI B has
increased because LIBOR has increased. Thus, the actual cash flows in the swap transaction now
become that FI B pays $1.00m ($11m - $10m) to FI A, and that FI A receives $1.00m and pays out
$0.10m to the intermediary. Each FI, of course, must pay the cash market liability rates.
g. If all barriers to entry and pricing inefficiencies between FI A's debt markets and FI B's debt
markets were eliminated, how would that affect the swap transaction?
If relative prices are the same in the markets of both FI A and FI B, then there are no potential
gains to trade and therefore no swap transactions can take place. Each FI will issue debt in their
respective debt markets.

Chapter 24: Macro-Hedge
12.
An FI has $500 million of assets with a duration of nine years and $450 million of liabilities with a
duration of three years. The FI wants to hedge its duration gap with a swap that has fixed-rate
payments with a duration of six years and floating rate-rate payments with a duration of two
years. What is the optimal amount of the swap to effectively macrohedge against the adverse
effect of a change in interest rates on the value of the FI’s equity?
Using the formula, NS = [(DA - kDL)A]/(DFixed – DFloating) = [(9 – 0.9x3)$500 million]/(6 – 2) = $787.5 million.

Liabilities and Equity
Fixed-rate assets
Total assets

$200
Rate-sensitive assets are repriced quarterly at the 91-day Treasury bill rate plus 150 basis points.
Fixed-rate assets have five years until maturity and are paying 9 percent annually. Rate-sensitive
liabilities are repriced quarterly at the 91-day Treasury bill rate plus 100 basis points. Fixed-rate
liabilities have two years until maturity and are paying 7 percent annually. Currently, the 91-day
Treasury bill rate is 6.25 percent.
a. What is the bank's current net interest income? If Treasury bill rates increase 150 basis points,
what will be the change in the bank's net interest income?
Interest income = 50(.0625 + .015) + 150(.09) = $17.375 million, and interest expense = 75(.0625 +
.01) + 100(.07) = $12.4375 million. Thus, net interest income = $4.9375 million.
After the interest rate increase, interest income = 50(.0775 + .015) + 150(.09) = $18.125 million,
interest expense = 75(.0775 + .01) + 100(.07) = $13.5625 million, and net interest income =
$4.5625 million for a decline of $375,000.

b. What is the bank's repricing or funding gap? Use the repricing model to calculate the change
in the bank's net interest income if interest rates increase 150 basis points.
Funding gap = Rate sensitive assets - Rate sensitive liabilities = 50 - 75 = - $25 million. The repricing
model states that ∆NII = GAP(∆ R) = -25(.015) = - $0.375 million. The bank is exposed to interest
rate increases since interest expenses increase more than interest income.
c. How can swaps be used as an interest rate hedge in this example?
A short hedge can be used to hedge the bank's interest rate risk exposure. The short hedge can be
implemented by selling futures or forward contracts, buying put options, or buying a swap of
liabilities. Swapping liabilities allows the institution to make fixed-rate liability payments in
exchange for a counter-party making the floating rate payments. Similarly, the FI could also swap
assets. The short hedge can be accomplished by swapping out fixed-rate asset payments in
exchange for floating-rate asset payments.
16.
Use the following information to construct a swap of asset cash flows for the bank in problem 14.
The bank is a price taker in both the fixed-rate market at 9 percent and the rate-sensitive market
at the T-bill rate plus 1.5 percent. A securities dealer has a large portfolio of rate sensitive assets
funded with fixed-rate liabilities. The dealer is a price taker in a fixed-rate asset market paying 8.5
percent and a floating-rate asset market paying the 91-day T-bill rate plus 1.25 percent. All
interest is paid annually.
a. What is the interest rate risk exposure to the securities dealer?
The securities dealer is exposed to interest rate declines.
b. How can the bank and the securities dealer use a swap to hedge their respective interest rate
risk exposures?

The two counterparties can use a swap of asset cash flows to hedge their respective interest rate
risk exposures. The bank would swap out fixed-rate asset payments in exchange for floating-rate
asset payments to yield positive cash flows when interest rates increase. The securities dealer
would swap out floating-rate asset payments in exchange for fixed-rate asset payments to yield
positive cash flows when interest rates decrease.
c. What are the total potential gains to the swap?
The total gains to the swap trade are 25 basis points. This is because the bank earns a 25 basis
point premium in the floating-rate market and a 50 basis point premium in the fixed-rate market.
d. Consider the following two-year swap of asset cash flows: An annual fixed-rate asset cash flow
of 8.6 percent in exchange for a floating-rate asset cash flow of T-bill plus 125 basis points.

f.
What are the sources of the swap gains to trade?
The gains to the swap trade emanate from the pricing discrepancy in the two cash markets. That
is, the bank earns a 50 basis point premium in the fixed-rate asset market, while only a 25 basis
point premium in the floating rate asset market. The swap allows both the bank and the securities
dealer to exploit their own comparative advantage in their respective cash market.
g. What are the implications for the efficiency of cash markets?
There must be some barrier that prevents the two firms from directly transacting in the other's
cash market (or equivalently raises the costs of these cross-market transactions). This barrier may
consist of regulatory restrictions or tax considerations. If, however, the barrier results from
information asymmetries, these potential gains to trade can be expected to disappear as the swap
market develops.
