NewZealanddollar .7265 .7272 1.3751 1.3765

Singaporedollar .6135 .6140 1.6287 1.6300

Solution:Equation5.12fromthetextimpliesSb(NZD/SGD)=Sb($/SGD)xSb(NZD/$)=.6135x1.3765=.8445.Thereciprocal,1/Sb(NZD/SGD)=Sa(SGD/NZD)=1.1841.Analogously,itisimpliedthatSa(NZD/SGD)=Sa($/SGD)xSa(NZD/$)=.6140x1.3765=.8452.Thereciprocal,1/Sa(NZD/SGD)=Sb(SGD/NZD)=1.1832.Thus,theNZD/SGDbid-askspreadisNZD0.8445-NZD0.8452andtheSGD/NZDspreadisSGD1.1832-SGD1.1841.

8. AssumeyouareatraderwithDeutscheBank.Fromthequotescreenonyourcomputerterminal,younoticethatDresdnerBankisquoting€0.7627/$1.00andCreditSuisseisofferingSF1.1806/$1.00.YoulearnthatUBSismakingadirectmarketbetweentheSwissfrancandtheeuro,withacurrent€/SFquoteof.6395.Showhowyoucanmakeatriangulararbitrageprofitbytradingattheseprices.(Ignorebid-askspreadsforthisproblem.)Assumeyouhave$5,000,000withwhichtoconductthearbitrage.WhathappensifyouinitiallyselldollarsforSwissfrancs?What€/SFpricewilleliminatetriangulararbitrage?

Solution:TomakeatriangulararbitrageprofittheDeutscheBanktraderwouldsell$5,000,000toDresdnerBankat€0.7627/$1.00.Thistradewouldyield€3,813,500=$5,000,000x.7627.TheDeutscheBanktraderwouldthenselltheeurosforSwissfrancstoUnionBankofSwitzerlandatapriceof€0.6395/SF1.00,yieldingSF5,963,253=€3,813,500/.6395.TheDeutscheBanktraderwillreselltheSwissfrancstoCreditSuissefor$5,051,036=SF5,963,253/1.1806,yieldingatriangulararbitrageprofitof$51,036.

IftheDeutscheBanktraderinitiallysold$5,000,000forSwissfrancs,insteadofeuros,thetradewouldyieldSF5,903,000=$5,000,000x1.1806.TheSwissfrancswouldinturnbetradedforeurostoUBSfor€3,774,969=SF5,903,000x.6395.TheeuroswouldberesoldtoDresdnerBankfor$4,949,481=€3,774,969/.7627,oralossof$50,519.Thus,itisnecessarytoconductthetriangulararbitrageinthecorrectorder.
