Practice Set and Solutions #1
What to do with this practice set?1
Practice sets are handed out to help students master the material of the course and prepare for
the final exam. These sets contain worked-out problems in corporate finance. This set is not
graded, and there is no need to hand-in the solutions. Students are strongly encouraged to
solve them, discuss the solutions with other course participants, and use the teacher's (e-mail)
to discuss any problems they might encounter.

a) Is there an arbitrage opportunity?
b) What will happen in the future?
Question 7
Given that the 3-month Danish interest rate is 4.41%, the U.S. rate of interest is 4.96, and the
spot rate in European terms is 6.44, what is the (approximate) 3-month forward rate of DKR
per USD?
Question 8
Both France and US are producing wines such as Cabernet Sauvignon. Suppose a bottle of
Cabernet Sauvignon sells for USD 18, in the U.S. An equivalent bottle, according to market
experts, sells in France for EUR 10.
a) According to PPP, and the law of one price, what should be the USD/EUR spot exchange
rate?
b) Suppose the Cabernet Sauvignon in the U.S. raises to $20 over the next year, while the
price of the French CS is expected to rise to EUR11. What would be the one-year forward
rate, USD/EUR?
Question 9
On January 1, your American firm is able to obtain a loan from a Swiss Bank at 3% p.a. The loan is
CHF 5m, to be fully repaid a year from now.
The sum will be invested in the US for one year.
The currenct spot rate is CHF 1.4515/USD.
During the year you expect 4% inflation in the US and 1% in Switzerland.

b) After borrowing do you have a short or a long position? Show in a pay-off diagram.
c) How can you hedge that position?
d) Calculate the cost of borrowing in CHF.
e) Calculate how much you need to repay in USD. If relative PPP holds? (We can also ask “if the
random walk theory holds?)
f) Calculate the cost of borrowing in per cent.

Question 10
Assume that the 1-month money market rate of interest in Sweden is 1.91% while in
Norway it is 2.06%. The spot exchange rate between the Swedish krona (SEK) and the
Norwegian krone (NOK) is 0.838 NOK/SEK.
a) Calculate potential arbitrage profits (in percentage terms) if the 1-month forward
exchange rate is 0.854 NOK/SEK.
b) Is it possible that the resulting arbitrage capital movements between the two countries
could trigger an international financial crisis? If the NOK/SEK rate is floating or fixed?
c) Suppose that the forward rate is unbiased predictor of the future spot rate. What is the
expected rate of depreciation? How will this information change your answer in b)?
Question 11
What is meant by the real exchange rate. Is it a stationary over time? What does it tell us?
Solution 11
The real rate is defined as q =
S t Pf
Pd
, where S = dom/for. Try to discuss what it is in relation
to PPP. What is real appreciation? What is real depreciation? Does PPP hold, in absolute or
relative form?

Solutions
Solution 1
You read the following quotes the (USD /DEM) rate: 0.4565 -0.4580
a) What is the quote for buying and selling DEMs?
The question you need to answer first is what is the “home” currency here? The answer is that
is the USD. Thus, you buy DEM at 0.4580 from the dealer, and sell DEM to the dealer at
0.4565. (Confirm with the rip-off rule)
a) Take the inverse of the exchange rates, and remember that bid price < ask price, and
the answer is 2.1834 - 2.19058
Solution 2
a) What is the EUR /USD rate?
(SEK 7.85/USD) / SEK10.69/EUR) = (SEK 7.85) * EUR/(SEK10.69) = 0.73
EUR/USD
b) The Financial Times web quotes the USD /EUR to 1.36 (the same day and time) Is
it correct? (What is the cross-rate here?)
Take the inverse of EUR/USD and get USD 1.36/EUR, which matches the
quotation in Financial Times quite exactly.
Solution 3
The US firm will view this as a purchase of CAD 1.25m against a total payment of
USD 1m. The unit price of one CAD is
USD 1m / CAD 1.25m = USD 0.80/CAD
The Canadian would view this as a purchase of USD 1m for CAD 1.25m, implying a
unit price of USD
CAD 1.25m / USD 1m = CAD 1.25/USD
Solution 4
a) For the British these quotes are indirect, since it is number of foreign currency units
over one domestic currency unit.
b) For the Danes this quote is direct since it is domestic units over one foreign unit
c) Outright quotations
CZJ/GBP 42.7616
DKK/GBP 11.30065
EUR/GBP 1.5168
NOK/GBP 12.3263

d) GBP 0.088423/DKK and GBP 0.0192/RUB
e) In this case the bid becomes the ask and the ask becomes the bid when do inverse
GBP/DKK: 0.088486 – 0.088490
GBP/RUB:
0.0191689 - 0.0191800
Solution 5
a) Spreads are given as the last three decimals. Thus the spread for the EUR/USD
is 960 – 918, the rest follows.
b) Mid-point quotation is given as (bid+ask)/2. Thus, the midpoint for EUR/USD is
EUR 1.2917/USD.
c) American: USD/JPY, USD/CHF, USD/CAD. European: EUR/USD, GBP/USB,
AUD/USD.
d) CAD 1.0139/USD
e) AUD 0.9578/CHF (show the calculations to confirm) No, Aussies use indirect
quotation.
f) EUR 1.2637/AUD show te calculations to confirm this
g) Since all quotes appear to be indirect quotation seen from the view of London,
London it is!
Solution 6
a) Bank A is selling ABC for 20.55. You buy ABC for 20.55. Next sell to bank B at
ABC/EUR 20.60 and make a profit of 0.05 for each transaction.
There is no risk in this, so it constitutes risk-free profits. No capital is invested, since the
transactions can be viewed as instantaneous. Profit is 0.05 on each transaction.
b)
This cannot continue, in the end the price will be the same everywhere. Arbitrage will
result in the same price for the same cash flow. We can also refer to this as least-cost pricing.
The seller with the lowest price attracts the costumers.
Solution 7
Apply the CIP relation, but be careful of the interest rates.
Here is one version:
[(F-S)/S] x (360/90) x 100 = (i – i*) / (1+i*)
and solve for F. The results are in the area of F = 6.43
Solution 8
a) S [EUR/USD] = P_eur / P_usd = EUR10/USD18 = EUR0.5556/USD.
This implied exchange rate can now be compared with the actual rate. However, this example
is a bit hypothetical.
b) F = EUR 11/USD 20 = EUR0.5500/USD

Solution 9
a) Calculate dollars received from borrowing.
USD received: CHF 5m / (CHF1.4515/USD) = USD 3.444712m
b) After borrowing what is your foreign exchange position? Show in a pay-off diagram.
You have a short position you gain if the foreign exchange rate appreciates (explain).
The pay off diagram will have a line with a negative 45 degree line.
c) How can you hedge that position?
The principle of hedging is to create an off-setting cash flow, a cash flow that moves in the
opposite direction to the risky pay-off you have. In other words you need to create a long
foreign exchange position in the same currency. Anything that can achieve an opposite cash
flow to the short position in the CHF constitutes a hedge. The hedge can be complete or
partial. A forward or a futures contract in CHF can achieve a 100 % hedge.
d) What is the cost of borrowing in CHF?
The cost of borrowing in CHF is CHF5m x 0.03 = CHF150 000
e) Calculate how much you need to repay in USD. If relative PPP holds?
In USD? We don’t know the future spot rate. If we assume that the random walk model holds,
we take today’s value as the best predictor, and our estimated cost is
CHF 150 000 / (CHF1.4515/USD) = USD103 341.37
The expected change in the spot rate next year, given by the inflation differential is (1%-4%) =
3%. Thus, if relative PPP holds the CHF will appreciate with 3% (or 0.03), against the dollar.
First, the expected exchange rate if relative PPP holds:
(CHF 1.4515/USD) x (1 + (- 0.03)) = (CHF/USD) x 1.45 (0.97) = CHF 1.4080/USD
The cost of borrowing in CHF is CHF150 000. We are going to repay CHF5,150,000.
In USD that is, assuming relative PPP
CHF 5,150,000/ (CHF1.4080/USD) = USD3,657,670.05
f) Calculate the cost of borrowing in per cent.
The cost of borrowing in per cent
[(USD3,657,670.05 /USD3,444,712) - 1] = 0.0618 or 6.18%
Solution 10

Notice there is no mentioning of a “home currency” or accounting currency here. The
quotations are done with the NOK as the home currency, so we will stick to that.
a) Calculate potential arbitrage profits (in percentage terms) if the 1-month forward
exchange rate is 0.854 NOK/SEK.
The pay off from investing 1 NOK in NOK for one month is
NOK 1 (1 + 0.0206/12) = NOK (1 + 0.00172) = NOK 1.00172
Investing 1 NOK in SEK gives (change to SEK, invest one month, use one the month
forward rate to change back)
NOK 1 [1/(NOK 0.838/SEK)] * (1 + 0.0191) * NOK 0.854/SEK
= NOK * SEK1.1933/NOK * (1 + 0.0001325)
= SEK 1.1933 * (1.0001325) * NOK 0.854/SEK
= SEK 1.19346 * NOK 0.854/SEK
= NOK 1.0192
CHECK THESE numbers!!!
It is more profitable to invest in SEK. The yield from SEK can directly compared with the
NOK yield because we used the forward rate to eliminate (hedge) the foreign exchange risk.
b) Is it possible that the resulting arbitrage capital movements between the two countries
could trigger an international financial crisis? If the NOK/SEK rate is floating or fixed?
In this case we talk about CIP. (We also ignore transaction costs since no bid-ask prices are
quoted.) Given no default risk between the two counter partners and no political risk, CIP is
an arbitrage condition, we know that F, S i, and i* must change to uphold the condition. If the
exchange rate S is fixed or not will not matter for this condition.
Can there be a currency crisis? This is a tricky question?
Your first answer might be: No risk of currency crises since CIP is just an arbitrage condition
that will be restored automatically. Therefore, no risk of a currency crisis.
But …
First, is the exchange rates fixed or floating?
Start with fixed.
Why are we observing a deviation from CIP? Normally we do not expect to see deviations
from CIP. And, we are getting market quotations. Thus the deviation is for real and must be
caused by 1) counter partner risk (default risk) in general between Swedish and Norwegian
bank. And/or there is treat of foreign exchange regulations being imposed during the month.
These regulations (perhaps a tax might remove part or all of the profit). Treats of FX
regulations, huge default risk across many banks in a country are indeed signs of an
international financial crisis.
If the exchange rate is floating?
The answer is that this will not change the argument above. The default risk and the political
risk would still be there. If we think this is just a temporary mistake, floating rates would help
to adjust back to CIP quicker (assuming no default or political risk).

c) Suppose that the forward rate is unbiased predictor of the future spot rate. What is the
expected rate of depreciation? How will this information change your answer in b)?
Given the information that F is an unbiased predictor F = Set+1 is not going to change our
conclusions and reasoning from above.
We know that the Forward rate is reflecting an expected depreciation F – S = 0.854 – 0.838 =
0.016.
In percentage (F-S)/S = 0.01909
On annual basis [* (360/30)*100]: 0.01909 * (360/30) * 100 = 22.91%
The interest rate differential is [(0.0206 – 0.0191)/ ( 1.0191)] * 100 = 0.1472 %
