  10. Interbank market transactions • Spot transaction • requires almost immediate delivery of foreign exchange. • Forward transaction • requires delivery of foreign exchange at some future date. • Currency Swap transaction • is the simultaneous purchase and sale of a foreign currency . © 2002 by Stefano Mazzotta

  11. Efficiency • The foreign exchange market is very efficient due to • its 24-hour trading schedule • extensive telecommunication network • shear size of the market • computerized quotation system © 2002 by Stefano Mazzotta

  12. 2. Rates and Quotations

  13. Price quotes • The prices are quoted in pairs: • Bid - price at which the bank buys the currency • Ask - price at which the bank sells the currency • The spread, i.e. | bid – ask |, is the profit of the bank (dealer) • Home country based quotes: • direct quote - a home currency price of a foreign currency, e. g., EUR/USD in France • indirect quote - a foreign currency price of home currency, e. g., USD/EUR in France © 2002 by Stefano Mazzotta

  14. Example • The pound sterling is quoted at $1.6618-35. • (This notation is a shorthand for 1.6618-1.6635 USD/GBP) • What is the “bid-ask” spread? 1.6635 - 1.6618 = $0.0017 What is the spread in percentage points? © 2002 by Stefano Mazzotta

  15. Example • The pound sterling is quoted in New York at $1.6618-35. This is a direct quote. • What is the indirect quote? • Therefore, the indirect quote is: 0.6011-18. • What is the direct quote of a dollar in London? © 2002 by Stefano Mazzotta

  16. Bid and ask quotes relation • Suppose, there are 2 currencies: A and B. • Then: • And: © 2002 by Stefano Mazzotta

  17. Example • The bank quote for is 1.6050-72 SF/$ • What is the SF/$ exchange rate for a customer who wants to exchange $ for SF? • What is the $/SF exchange rate for a customer who wants to exchange SF for $? © 2002 by Stefano Mazzotta

  18. The U.S. dollar based quotations • If currencies are quoted against USD, they can be quoted in • American terms: $ per unit of foreign currency • European terms: units of foreign currency per 1$ • Nowadays, almost all except U.K. and Euro exchange rates are expressed in European terms. © 2002 by Stefano Mazzotta

  20. Cross rates • Definition: • Exchange rate between two foreign currencies. • Reason: • Most currencies are quoted against the U.S. $ and not against each other. • Result: • The U.S. $ rate can be used to compute a cross rate. © 2002 by Stefano Mazzotta

  21. Example of cross rate quotation • See http://money.cnn/markets/currencies • See also http://www.bloomberg.com/markets/fxc.html © 2002 by Stefano Mazzotta

  23. Example • Let e(USD/EUR) = 0.97 • Let e(USD/CAD) = 0.63 • What is the EUR/CAD cross-rate? • So, 1 Canadian dollar can buy 0.65 euros. © 2002 by Stefano Mazzotta

  24. The general rule for cross rates • Suppose, there are 3 currencies: A, B, and C. • Suppose, the spot exchange rates e(A/B) and e(B/C) are known. • What is the cross exchange rate e(A/C)? © 2002 by Stefano Mazzotta

  25. Cross rates and bid-ask spreads • With bid-ask spreads, the general rule to compute cross rates is: © 2002 by Stefano Mazzotta

  26. Example: Question • The spot quote for CHF/USD is 1.5150-72 • The spot quote for CAD/USD is 1.5810-56 • What is the direct spot quote for CHF/CAD? © 2002 by Stefano Mazzotta

  27. Example: Solution (part I) © 2002 by Stefano Mazzotta

  28. Example: Solution (part II) • So, the direct spot CHF/CAD quote is 0.9555-96. © 2002 by Stefano Mazzotta

  29. 3. Currency Arbitrage

  30. Currency arbitrage • Definition: • Realization of a riskless profit by simultaneous buying a currency in one market and selling it in another market. • Cause: • Exchange rate quote inconsistencies across different money centers. © 2002 by Stefano Mazzotta

  31. Example • Bank of America’s quote of $1C is $0.7056-76. • Royal Bank’s quote of $1C is $0.7038-52. • How to make easy money? • Buy $C from Royal Bank by paying $ and sell $C to BoA receiving $. • Make about $0.0004 per $ or $40 per $100,000. © 2002 by Stefano Mazzotta

  32. Arbitrage exclusion condition • In the absence of taxes, etc., the arbitrage exclusion condition is to have overlapping bid-ask quotes. Bid1 Ask1 Bid2 Ask2 © 2002 by Stefano Mazzotta

  33. Triangular arbitrage • The essence: • 1 unit of currency A buys currency B • Currency B buys currency C • Currency C buys more than 1 unit of currency A A A B C © 2002 by Stefano Mazzotta

  34. Example: part 1 - the set up • The GBP is bid at 1.9809 in New York: • e(USD/GBP) = 1.9809 • Swiss franc is offered at $0.6251 in Zurich: • e(USD/CHF) = 0.6251 • London offers pounds sterling at CHF 3.1650: • e(CHF/GBP) = 3.1650 • Amount of money: $1,000,000 © 2002 by Stefano Mazzotta

  35. Example: part 2 - the strategy • Sell $1,000,000 in Zurich at e(USD/CHF) and receive CHF 1,599,744.04. • Sell these Swiss francs in London at e(CHF/GBP) and receive GBP505,448.35. • Sell the pounds sterling in New York at e(USD/GBP) and receive $1,001,242.64. • Net profit: $1,242.64 © 2002 by Stefano Mazzotta

  36. Example: part 3 - market adjustment mechanism • Large number of arbitrage transactions will cause: • Swiss franc to appreciate with respect to U.S. dollar in Zurich • Swiss franc to depreciate against the pound sterling in London • Sterling will fall in New York • Markets adjust quickly and eliminate arbitrage opportunities © 2002 by Stefano Mazzotta

  37. Triangular arbitrage condition • For triangular arbitrage to exist, the following must hold: • Or, equivalently: © 2002 by Stefano Mazzotta
