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” “If you think writing about the fortunes of the stock market is tricky, try getting your arms around currencies” Alan Greenspan, former U.S Federal Reserve chairman 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

Arbitrage Opportunity Arbitrage constraints on spot exchange rate quotes: A dealer’s bid (offer) cannot be higher (lower) than current interbank offer (bid) Bids (offers) posted by a dealer must be lower (higher) than the implied cross-rate offers (bids) available in the interbank market

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 78.13 / 78.17 85.781 / 85.785 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 CAD in the interbank market and selling it to the dealer, for a profit of JPY 0.01 per CAD JPY from the dealer and selling it in the interbank market, for a profit of CAD 0.01 per JPY 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? Transaction 1, 2, 3 Transaction 2,1, 3 Transaction 3, 1, 2 Culled from CFA Curriculum, Level II, Volume 1

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) 1.0145 270-day LIBOR (AUD) 4.87% 270-day LIBOR (CAD) 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: -0.0346 -0.0254 +0.0261

Solution Ff/d Discount or premium = Sf/d (if – id) x 270/360 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: = 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. Ff/d Discount or premium = Sf/d (if – id) x 270/360 1 + (id x 270/360)

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) 0.7825 / 0.7830 Three-month points -12.1 / -10.0 Three-month LIBOR (NZD) 3.31% Three-month LIBOR (USD) 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.

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) 1.4939 / 1.4941 One month -8.3 / -7.9 Three months - 25.4 / - 24.6 Six months -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?

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 Covered Interest Rate Parity Uncovered Interest Rate Parity Assertion: Expected % Change in Spot Rate f/d = if - id Class Discussion: Use the following comparable yield environments to attempt the questions that follow: Domestic Yield = 15% Foreign Yield = 3% Q1. Compute the expected change in spot FX rate for uncovered interest rate parity to hold Q2. What is the preferred investment if domestic currency depreciated by 10% 15% Spot and Forward Rates as Predictors of Future Spot Rates F will be an unbiased forecast of future S assuming both covered and uncovered parities hold Theory vs. reality? Can current S be a good predictor of future S given very high volatility of S (Random Walk Model) ?

International Parity Relations Questions An Australian-based fixed income asset manager is deciding whether to allocate money between Australia and Japan. Note that the base currency in the exchange rate quote is the domestic currency for the asset manager. JPY / AUD spot rate (mid-market) 79.25 One-year forward points (mid-market) -301.9 One-year Australian deposit rate 5% One-year Japanese deposit rate 1% Q1. Based on uncovered interest rate parity, over the next year, the expected change in the JPY / AUD rate is closest to a(n): Decrease of 10% Decrease of 4% Increase of 4% Q2. The best explanation why this prediction may not be very accurate is that: Covered interest rate parity does not hold in this case The forward points indicate that a riskless arbitrage opportunity exists There is no arbitrage condition that forces uncovered interest rate parity to hold

International Parity Relations Q3. Using the forward points to forecast the future JPY / AUD spot rate one year ahead assumes that: Investors are risk neutral Spot rates follow a random walk It is not necessary for uncovered interest rate parity to hold Q4. If the asset manager completely hedged the currency risk associated with a one-year Japanese deposit using a forward rate contract, the one-year all-in holding return, in AUD, would be closest to: 0 percent 1 percent 5 percent Q5. Forecasting that the JPY / AUD spot rate one year from now will equal 79.25 assumes that Spot rates follow random walk It is necessary for uncovered interest rate parity to hold

International Parity Relations The fixed income manager collects the following information, and uses it along with the international parity conditions in order to estimate investment returns and future exchange rate movements Today’s one year LIBOR Currency Pair Spot Rate Today JPY 0.10% JPY / USD 81.30 USD 0.10% USD / GBP 1.5950 GBP 3.00% JPY / GBP 129.67 Q6. If covered interest rate parity holds, the all-in, one year investment returns to a Japanese investor, whose currency exposure to the GBP is fully hedged is closest to 0.10 percent b. 0.17 percent c. 3.00 percent Q7. If uncovered interest rate parity holds, between today and one year from now, the expected movement in the JPY / GBP currency pair is closest to: a. 126.02 b. 129.67 c. 130.05 Q8. If uncovered interest rate parity holds, between today and one year from now the expected movement in the JPY / USD currency is closest to a. -1.60 percent b. +0.00% c. +1.63 percent

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 HENCE, no one makes money by moving capital across the globe

Long-run Exchange Rate Equilibrium The 3 models used by IMF Consultative Group on Exchange Rate Issues (CGER): Macroeconomic balance approach External sustainability approach Reduced-form econometric method Reality check: How well do these models work in predicting long-run exchange rate path?

FX Carry Trade Basis for FX Carry Trade Execution Strategy Return Distribution: Risk and Reward Positive Kurtosis (More smaller gains/losses than normal distribution) Negative Skewness and fat tails (More frequent and larger losses than normal distribution) Managing the downside crash risk Volatility filter Currency Valuation using PPP

Questions Q1. Carry trade can be profitable when Covered interest rate parity does not hold Uncovered interest rate parity does not hold The international Fisher effect does not hold Q2. Overtime, the return distribution of the FX carry trades is most likely to resemble: Normal distribution with fat tails Distribution with fat tails and a negative skew Distribution with thin tails and a positive skew Q3. The volatility of returns of funds using FX carry trade relative to equity base is best explained by: Leverage Low deposit rates in the funding currency The yield spread between the high – and low-yielding currencies Q4. Which of these risk management strategies is most likely to reduce some of the negative tail risk associated with FX carry trades: Use forward contracts to sell the funding currency Exit the carry trade position when the implied FX volatility drops below a certain threshold Exit the carry trade when the funding currency drops below its PPP Level

Questions A Tokyo-based asset manager enters into a carry trade position based on borrowing in yen and investing in one-year Australian LIBOR Today’s 1-yr LIBOR Currency pair Spot Rate Today Spot Rate 1-yr Later JPY 0.10% JPY/USD 81.30 80.00 AUD 4.50% USD/AUD 1.0750 1.0803 Q1. After one year, the all-in return to this trade, measured in JPY terms would be closest to: +1.84% +3.23% +5.02%

Questions A Tokyo-based asset manager enters into a carry trade position based on borrowing in yen and investing in one-year Australian LIBOR Today’s 1-yr LIBOR Currency pair Spot Rate Today Spot Rate 1-yr Later JPY 0.10% JPY/USD 81.30 80.00 AUD 4.50% USD/AUD 1.0750 1.0803 Q1. After one year, the all-in return to this trade, measured in JPY terms would be closest to: +1.84% +3.23% +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%.!!!
