International Finance Exchange Rates Bill Reese
Learning Objectives • In this unit we will learn: • How to interpret direct and indirect exchange rates • How to determine cross-rates • How rates are quoted • How to calculate the bid-ask spread
Basic Terms • Spot Rate • The price of a currency in terms of another currency for a trade today • Forward Rate • Price agreed upon today for a trade to be executed at a specified future date (30, 60, 90, 180 or 360 days)
Basic Terms • Direct quote • American quote • Domestic currency/foreign currency • Dollars needed to buy one unit of foreign currency • $/€
Basic Terms • Indirect quote • European quote • Foreign currency/domestic currency • Units of foreign currency needed to buy one dollar • €/$
Quotes • Currency is a commodity • Bananas • $0.5/pound = 2 lbs. for a dollar • Price of dollar = €.813 • Price of a euro = $1.23
Quotes • Currency in denominator is the one being priced • .813 €/$ • 1.23 $/€
Quotes • You have dollars and want euros $ → € • Selling dollars • Buying euros • You have euros and want dollars € → $ • Selling euros • Buying dollars
Quotes • You have $5.00. How many euros is it worth if XR is 1.23 $/€? • Multiply or divide? • Direct quote: $5 x 1.23 $/€ • Note that $ won’t cancel out • Must invert • Indirect quote or divide
Quotes • $5 ÷ 1.23 $/€ = $5 x 1/1.23 €/$ = $5 x .813 €/$ = €4.065
Quotes • Suppose you have €30 and want dollars? • €30 x 1.23 $/€ = $36.90 • Note how €s cancel out in numerator and denominator
Cross Rates • Cross exchange rate • One foreign currency per unit of another foreign currency 1.23 $/€ and 1.81 $/£ • Cross-rate between euro and pound
Cross Rates • Multiply to cancel out $ 1.23 $/€ x 1.81 $/£ Can’t do it – must divide or invert 1.23 $/€ ÷ 1.81 $/£ = 1.23 $/€ x 1/1.81 $/£ = 0.68 £/€
Cross Rates • If you want €/£ • Take reciprocal • 1/0.68 £/€ = 1.47 €/£
Bid and Ask • There are two XRs • Bid: price dealer will pay you for your currency • Rate if you want to sell • Ask: price dealer will sell you units of a currency for • Rate if you want to buy • Ask > Bid
Bid and Ask • Indirect quotes • Ask: 1.29 SF/$ • Bid: 1.28 SF/$ • Direct quotes • Ask: .78125 $/SF • Bid: .7752 $/SF • Bid in $ = Ask in SF • Bid in SF = Ask in $
Bid and Ask • Example • Ask: .0091 $/¥ • Bid: .0090 $/¥ • $150 to convert to yen • Buy yen at price of .0091 $/¥ • Or sell dollars at price of 1/.0091 ¥/$ • $150 ÷ .0091 $/¥ = ¥16,483.5
Bid and Ask • Change your mind – convert back • Sell yen at price of .0090 $/¥ • Or buy dollars at price of 1/.0090 ¥/$ • ¥16,483.5 x .0090 $/¥ = $148.35
Bid and Ask • $150 → $148.35 • Lost $1.65 • Lost 1.1% of $150 you started with • Bid-Ask Spread Spread = Ask – Bid Ask = (.0091 - .0090)/.0091 = 1.1%
Bid and Ask • Spread • Transaction cost for round-trip transaction • Decreases with greater amounts of currency • Increases with less frequently traded currency
