Introduction
“Having endeavored to
forecast exchange rates
for more than half a
century, I have
understandably
developed significant
humility about my ability
in this area”
Alan Greenspan, former
U.S Federal Reserve
chairman
“If you think writing about
the fortunes of the stock
market is tricky, try
getting your arms around
currencies”
Bill Gross, Co-founder and
co-chief investment officer
at PIMCO

Bid-Ask Spread
Concepts Refresher
• Exchange Rate Quotation, Price Currency, Base Currency, Spot Rate, Forward Rate
The bid-offer quote:
• Bid is always lower than offer (Buy Low, Sell High)
• Counterparty has an option not obligation to deal. He can either “hit the bid” (sell) or “pay the offer”
(buy)
Factors affecting bid-offer spread:
• Interbank market liquidity (currency types, time of the day, market volatility)
• Transaction size
• Relationship
7
Arbitrage Opportunity
Arbitrage constraints on spot exchange rate quotes:
1. A dealer’s bid (offer) cannot be higher (lower) than current interbank offer (bid)
2.
Bids (offers) posted by a dealer must be lower (higher) than the implied cross-rate offers
(bids) available in the interbank market
8
Questions
The following are spot rate quotes in the interbank market:
USD/EUR
1.4559 / 1.4561
JPY/USD
81.87 / 81.89
CAD/USD
0.9544 / 0.9546
SEK/USD
6.8739 / 6.8741
Q1. What is the bid-offer on the JPY / CAD cross rate implied by the interbank market
a.
78.13 / 78.17
b.
85.781 / 85.785
c.
85.76 / 85.80
Q2. If the dealer quoted a bid-offer rate of 85.73 / 85.75 in JPY/CAD, then a triangular arbitrage would involve buying
a.
CAD in the interbank market and selling it to the dealer, for a profit of JPY 0.01 per CAD
b.
JPY from the dealer and selling it in the interbank market, for a profit of CAD 0.01 per JPY
c.
CAD from the dealer and selling it in the interbank market, for a profit of JPY 0.01 per CAD
Q3. A market participant is considering the following transactions:
Transaction 1: Buy CAD 100million against the USD at 15:30 London time
Transaction 2: Sell CAD 100million against the KRW at 21:30 London time
Transaction 3: Sell CAD 10million against the USD at 15:30 London time
Given the proposed transactions, what is the most likely ranking of the bid – ask spreads, from tightest to widest,
under normal market conditions?
a.
Transaction 1, 2, 3
b.
Transaction 2,1, 3
c.
Transaction 3, 1, 2

Solutions
Q1. C
Explanation: JPY/CAD = JPY/USD X USD/CAD
Note that USD/CAD is the inverse of CAD/USD which is given in the question. Inverting CAD/USD to get USD/CAD involves
finding the reciprocal of CAD/USD offer to get the USD/CAD bid (1/0.9546 = 1.04756), and finding the reciprocal of CAD/USD
bid to get the USD/CAD offer (1/0.9544 =1.04778). Remember bid “must” always be less than offer. Hence:
Bid: 81.87 x 1.04756 = 85.76
Offer: 81.89 x 1.04778 = 85.80
Q2: C
The dealer’s quote violates no arbitrage condition. The dealer’s offer for JPY/CAD is lower than the Interbank implied cross rate
bid. Hence, arbitrage is possible. Since the dealer is willing to sell CAD at a price cheaper than the interbank market is willing to
buy CAD (85.75 vs 85.76), arbitrage will involve buying CAD at 85.75 by paying the offer to the dealer and hitting the bid in the
interbank market, resulting in a profit of 0.01 JPY per CAD.
Q3: C
The most liquid transaction is 3 driven by lower size (10million), timing (15:30 London time) and currency type (USD and CAD)
The next liquid is transaction 1. It has everything as 3 except for bigger transaction size, which means higher risk (wider spread)
The least liquid is 2 driven by bigger transaction size, less liquid currency pair (KRW, CAD) and time (21:30 London time)

Forward Markets
Forward Premium/Discount
• Using the “covered interest rate parity equation”
Class Example
The following table shows the mid-market for the current CAD/AUD spot exchange rate as well as for
for AUD and CAD 270-day LIBOR (annualized)
Spot (CAD / AUD)
270-day LIBOR (AUD)
270-day LIBOR (CAD)
1.0145
4.87%
1.41%
Q1: Will AUD trade at a forward discount or premium?
Q2: The forward premium or discount for a 270-day forward contact for CAD/AUD would be closest to:
a.
-0.0346
b.
-0.0254
c.
+0.0261
11
Solution
Q1: AUD will trade at a forward discount because AUD rate is higher than CAD. Currency with
higher interest rate will trade at a forward discount.
Q2: It has to be forward discount, hence option C is out. The direct formula for Forward discount
or premium can be used adjusting for time:
Ff/d Discount or premium = Sf/d (if – id) x 270/360
1 + (id x 270/360)
= 1.0145 (1.41% - 4.87%) x 270/360
1 + (1.41% x 270/360)
= -0.0254
Or Use the Covered Interest Rate Parity equation to estimate the forward quote and subtract the
spot rate from it.
12
Forward Markets
Mark-to-Market Value of Forward Contracts (4 simple steps)
• Create an equal and offsetting position
• Determine the appropriate all-in forward rate
• Calculate the cash flow at settlement day
• Calculate the present value
Class Example:
Sometimes ago, Laurier Bay Capital, an investment fund based in Los Angeles, hedged a long
exposure to the New Zealand dollar by selling NZD 10 million forward against the USD; the all-in
forward price was 0.7900 (USD/NZD). Three months prior to the settlement date, Laurier Bay wants to
mark this forward position to market. The bid-offer price for the USD/NZD spot rate, the three month
forward points, and the three-month LIBORs (annualized) are as follows:
Spot rate (USD / NZD)
Three-month points
Three-month LIBOR (NZD)
Three-month LIBOR (USD)
0.7825 / 0.7830
-12.1 / -10.0
3.31%
0.31%
Q1: Will Laurier Bay receive cash inflow or make cash outflow from the mark-to-market position?
Q2: What is the all-in bid rate for delivering NZD against the USD three months from now?
Q3: Calculate the mark-to-market value of the Laurier Bay’s forward position.
13
Solutions
Q1: To determine cash inflow or outflow compare currency position to currency performance
Long position
Appreciate
= Cash inflow
Short position
Depreciate
= Cash inflow
Long position
Depreciate
= Cash outflow
Short position
Appreciate
= Cash outflow
In this question, Laurier is shorting NZD and NZD has depreciated in value from 0.7900 to the current spot
rate of 0.7825/0.7830. Hence, he will receive cash inflow
Q2: All in bid rate for for delivering NZD = Current bid rate + 3-month forward points/10,000
= 0.7825 + (-12.1/10,000)
= 0.78129
Q3:
At maturity, he receives NZD10m in dollar value at exchange rate of 0.7900 USD/NZD. This gives USD7.9m.
By entering into an equal but offsetting position now (buy NZD10m) using all-in rate of 0.7820 (0.7830 + (10/10,000)), he buys NZD 10m at dollar value of USD7.82m at maturity 3 months from now.
Hence, he has a net positive cash flow of USD 7.9m – 7.82m = USD 80,000. This future cash flow is then
discounted to the present using USD rate = 80,000/(1+ 0.31% x 90/360) = USD 79,938

Forward Markets
Mark-to-market Value of Forward Contracts using FX Swap
*****FOCUS ON MIDPOINT*****
Example (FX Swap)
Six months ago, a dealer sold CHF 1million forward against the GBP for a 180-day term at an all-in
rate of 1.4850 (CHF/GBP). Today, the dealer wants to roll this position forward for another six months
(i.e. the dealer will use an FX swap to roll the position forward). The following are the current spot rate
and forward points being quoted for the CHF / GBP currency pair:
Spot rate (CHF / GBP)
One month
Three months
Six months
1.4939 / 1.4941
-8.3 / -7.9
- 25.4 / - 24.6
-56.5 / -54.0
Q1: Will the dealer make a positive or negative cash flow on the settlement day?
Q2: Calculate the cash flow the dealer will realize on the settlement day
Q3: What is the all-in rate the dealer will use today to sell the CHF 6 months forward against the GBP?
15
Solutions
Q1. In FX Swap, the mid-point of bid and offer is used for comparison. Mid-point of the spot rate is (1.4939
+1.4941)/2 = 1.4940. Comparing this mid-point with CHF/GBP 1.4850 shows that GBP now has a higher value
(has appreciated) and CHF has a lower value (has depreciated). Remember, the dealer was short CHF
1million, hence he receives a cash inflow on the settlement day (today).
Q2. By selling CHF 1m forward at CHF/GBP 1.4850, the dealer receives GBP 673,400.67 (1m/1.4850) at
settlement day.
The dealer must buy CHF 1m at settlement day (today) to meet the forward contract obligation. He buys this
using the mid-point of the spot rate CHF/GBP 1.4940. This costs him GBP 669,344.04 (CHF1m/1.4940).
His net position is = What he receives – What he pays
= GBP 673,400.67 – 669,344.04
= GBP 4,056.63 (No need to find PV because this is happening now)
Q3. Use the spot mid-point + Appropriate forward points
Selling CHF forward means buying GBP forward. This implies using the forward point on the offer side.
The all-in rate
= 1.4940 + (-54/10,000)
= 1.48860

International Parity Relations
Purchasing Power Parity
• Absolute PPP
• Relative PPP
• Ex ante PPP
The Fisher Effect and Real Interest Rate Parity
International Fisher Effect
Summary:
• If CIRP holds, interest rate differential = forward discount or premium
• If UIRP holds, interest rate differential = expected % Change in spot exchange rate
• If CIRP and UIRP hold, forward rate will be an unbiased predictor of future spot rate
• If all the parity conditions hold, expected % change in spot exchange rate
= nominal interest rate differential (yield spread) between countries
= forward premium or discount
= expected inflation differential

a. +1.84%
b. +3.23%
c. +5.02%
Answer:
1. Get the cross rates of JPY/AUD today and 1-yr later (81.3x 1.0750 = 87.4, and 80 x 1.0803 = 86.42)
2. Borrow JPY (say 1JPY, this can be any amount), convert it to AUD and invest the AUD equivalent at
AUD rate of 4.50%. 1 year from now, this gives 1/87.40 x (1 + 4.5%) = 0.01196 AUD
3. Convert the AUD to JPY using spot rate one year from now = 0.01196 x 86.42 = 1.0333. This gives
a gross return of 3.33%. Subtracting the JPY borrowing cost of 0.10%, the net return is 3.23%.!!!
