address the learning outcome statements set forth by CFA Institute This topic is also covered in:
Study Session 16EXAM FOCUS
This topicreview coversthe calculation of price and value for forwardcontracts,
specifically equity forwardcontracts,T-bondforwardcontracts,currency forwards,
and forward(interest)rate agreements.Youneedtohaveagood understanding of the
no-arbitrage principle that underlies these calculations becauseit isusedinthe topic
reviewsof futures andswapspricingaswell Thereareseveral important price and value
formulasinthisreview Aclearunderstandingof thesourcesand timing of forward
contractsettlementpaymentswill enableyoutobe successfulonthis portion of the
examwithout dependingonpurememorizationof these complex formulas In thepast,
candidates have been testedontheir understanding of the relationship of thepayments
atsettlementtointerestratechanges,assetpricechanges, and index level changes The
pricingconventionsfor the underlyingassetshave been tested separately The basic
contractmechanicsarecertainly “fair game,”sodon’t overlook theeasystuff by spending

WARM-UP: FORWARD CONTRACTS
Theparty tothe forwardcontractthat agreestobuy the financialorphysicalassethas

Wewill illustrate the basic forwardcontractmechanics throughanexample basedon
the purchase and sale ofaTreasury bill.Notethat while forwardcontracts onT-billsare
usually quotedintermsofadiscountpercentagefrom facevalue,we usedollar prices

WARM-UP:FORWARDCONTRACT PRICE DETERMINATION
TheNo-Arbitrage Principle
Thepriceofaforwardcontractisnotthepricetopurchase thecontractbecause thepartiesto aforwardcontracttypicallypaynothingto enterintothecontract atitsinception.Here,pricereferstothecontractpriceoftheunderlyingassetunder theterms
oftheforwardcontract.This price may beaU.S.dollaroreuro pricebutit isoften
expressedas aninterestrate orcurrencyexchangerate.For T-bills,the price willbe
expressedas anannualizedpercentagediscountfrom facevalue;forcoupon bonds, itwillusually be expressedas ayieldtomaturity;for theimplicitloan inaforwardrate
agreement (FRA), itwillbeexpressedasannualized LondonInterbankOfferedRate(LIBOR);andforacurrency forward, it isexpressedas anexchangeratebetweenthe
twocurrenciesinvolved.However it isexpressed, thisrate,yield,discount,ordollar
amountisthe forward priceinthecontract.
The price thatwewishtodetermineistheforwardprice that makes the valuesof
both thelong andthe short positionszero at contract initiation.Wewillusetheno¬
arbitrage principle-, there shouldnotbeariskless profittobegained byacombinationof
aforwardcontractposition with positionsinotherassets.This principleassumesthat
(1)transactionscosts are zero, (2) thereare norestrictionsonshort salesor ontheuse
of short saleproceeds, and(3)bothborrowing and lendingcanbedoneinunlimited
amounts attherisk-freerateofinterest.Thisconceptissoimportant,we’llexpress it in
aformula:
forwardprice =pricethat wouldnotpermitprofitable riskless arbitrageinfrictionless
markets
ASimpleVersionof the Cost-of-Carry Model
Inordertoexplain the no-arbitrage conditionasitappliesto the determinationof
forward prices,wewill firstconsideraforwardcontract on an assetthatcostsnothing
to storeand makesno payments toitsowneroverthe lifeofthe forwardcontract.Azero-coupon(purediscount) bondmeetsthesecriteria.Unlike goldorwheat, ithas
no storage costs;unlikestocks, thereare nodividendpayments toconsider;and unlike
coupon bonds,itmakesnoperiodicinterestpayments.

Trang 11StudySession 16 Cross-Reference to CFA InstituteAssigned Reading#47- Forward Markets and Contracts
The general form for the calculation of the forwardcontractpricecanbe statedas
S0 =spotpriceatinception of thecontract (t = 0)
Rf =annual risk-freerate
T =forwardcontract termin years
Example: Calculating the no-arbitrage forwardprice
Considera3-monthforwardcontract on azero-coupon bond withaface value of
$1,000thatiscurrentlyquotedat $500,andsuppose that theannualrisk-freerate is
6%.Determine the priceoftheforwardcontractundertheno-arbitrageprinciple
Cash and CarryArbitrageWhen the Forward ContractisOverpriced
Suppose the forwardcontractisactually tradingat$510rather than the no-arbitrage
price of$507.34 Ashort positioninthe forwardcontractrequires the delivery of this
bond three monthsfromnow.Thearbitragethatwe examinein thiscase amounts
toborrowing $500attherisk-freerateof 6%,buyingthebondfor $500,and
simultaneously taking the short positioninthe forwardcontract onthezero-coupon
bondsothatwe areobligated todeliverthebondatthe expiration of thecontractfor
Trang 12the forwardcontract(theforwardcontractprice)torepaythe $500 loan The totalamount torepaytheloan, sincethetermof the loanisthreemonths, is:
loanrepayment=$500x(l ,06)°'25 =$507.34
Thepaymentof $510wereceivewhenwedeliver the bondatthe forward priceis
greaterthanourloanpayoff of$507.34,andwewill have earnedanarbitrageprofit of
$510-$507.34=$2.66.Noticethat thisisequaltothe difference between the actualforward price and the no-arbitrage forward price Thetransactionsareillustratedin

Professor’sNote: Here’sacouplehintstohelpyouremember whichtransactions
toundertakeforcash and carry arbitrage:(1)always buyunderpricedassetsandsell overpricedassets(“buylow,sell high”), and(2)takeopposite positions inthe
spotandforwardmarkets.So,ifthefuturescontractisoverpriced,you want totakeashort positioninthosefutures(whichobligatesyoutosellatafixedprice)
Becauseyou goshortintheforwardmarket, youtake theoppositepositioninthe
spotmarket and buy theasset.Youneedmoneyto buy theasset, soyouhavetoborrow Therefore,thefirststepincash andcarryarbitrageat its mostbasicis:

Trang 15StudySession 16 Cross-Reference to CFA InstituteAssigned Reading#47- ForwardMarketsandContracts
Noticethat the forward price,FP, isthe forward price agreedto attheinitiationof the
contract, notthecurrentmarket forward price In otherwords,asthespotand forward
market prices changeoverthe lifeof thecontract,oneside(i.e.,shortorlongposition)
winsand the other side loses.Forexample, if the marketspotand forward prices
increaseafter thecontractis initiated,the long position makesmoney,the valueof the
long positionispositive, and the value of the short positionisnegative If thespotand
forward pricesdecrease,the short position makesmoney
Professor’sNote:Unfortunately,youmustbe ableto usetheforwardvaluation
formulasontheexam.Ifyou’re goodatmemorizingformulas,thatprospect
shouldn’tscare youtoomuch.However,ifyoudon’t like memorizingformulas,
here’s another waytoremember howtovalueaforwardcontract:the long
position willpaytheforwardprice (FP)atmaturity (time T)andreceivethe
spotprice(ST). The valueofthecontract to the longpositionatmaturityis
what he willreceiveless what he willpay:ST-FP.Priortomaturity(attimeT), the valuetothe longisthepresentvalueof ST(whichisthespotpriceat time tof St)less thepresentvalueoftheforwardprice:St — FP
(l+ Rf)T-‘ ‘
So, ontheexam,think “longpositionis spotprice minuspresentvalueof forwardprice.”
Example: Determining value ofaforwardcontractpriortoexpiration
Inour3-monthzero-couponbondcontractexample,wedetermined that theno¬
arbitrage forwardpricewas$507.34 Suppose that aftertwomonths thespotprice on
the zero-coupon bondis $515,and the risk-freerateisstill 6% Calculate the value of
the long and short positionsinthe forwardcontract.
Answer:
$507.34
V2 (oflong position aftertwomonths) =$515—
V2 (ofshort position aftertwomonths) =—$10.12
=$515-$504.88=$10.12
1.061/12
Anotherwayto seethisisto notethat because thespotprice has increasedto$515,
thecurrentno-arbitrage forward priceis:
FP=$515x1.061/12 =$517.51
The long position has mademoney (andthe short position has lost money) because
the forward price has increased by $10.17 from$507.34to$517.51sincethecontract

Professor’sNote:In practice, wewould calculate thepresentvaluefromthe

giveninmonths (e.g.,two months)calculateT using maturitydividedbynumberof

WARM-UP:LIBOR-BASEDLOANSANDFORWARDRATE AGREEMENTS
Eurodollar depositis thetermfordepositsinlargebanksoutsidetheUnited States
denominatedinU.S.dollars The lendingrate ondollar-denominated loans between
banksiscalled the London Interbank OfferedRate(LIBOR).Itisquotedas an
annualizedratebasedon a360-dayyear.Incontrast toT-billdiscount yields,LIBOR is
anadd-onrate,likeayieldquote on ashort-termcertificateofdeposit.LIBORisused
as areferenceratefor floatingrateU.S.dollar-denominated loans worldwide
Trang 22i Example:LIBOR-based loans
Computetheamountthatmustberepaidon a$1 million loan for 30days if 30-day
LIBOR isquotedat6%
Answer:
Theadd-oninterest iscalculatedas$1million x0.06x (30/360) =$5,000.Theborrowerwouldrepay$1,000,000 + $5,000=$1,005,000 attheendof 30days
LIBORispublished daily bythe British Banker’s Association andiscompiledfrom
quotesfromanumberoflargebanks; somearelarge multinational banks basedin
othercountriesthat have London offices Thereisalsoanequivalenteurolendingrate
calledEuribor, orEuropeInterbankOfferedRate.Euribor,established inFrankfurt, is
published bytheEuropeanCentralBank
Thelong positioninaforwardrate agreement (FRA) isthepartythatwouldborrow
themoney(longthe loanwith thecontractpricebeingthe interestrate ontheloan).Ifthe floatingrate at contractexpiration(LIBORforU.S.dollar deposits and Euribor for
eurodeposits) isabove theratespecifiedinthe forwardagreement,the long positioninthecontract canbeviewedastherighttoborrowat below marketratesand thelongwillreceivea payment.Ifthefloatingrate atthe expirationdateisbelowtheratespecifiedin
the forwardagreement,the short willreceiveacashpaymentfromthelong.(Theright
tolendatabove marketrateswould haveapositivevalue.)
Professor’sNote: Wesay “can be viewed as” becausean FRAissettledin cash,
sothereis norequirementtolendorborrow theamountstatedinthecontract.
Forthisreason, the creditworthinessofthelongpositionis not afactorin
the determinationoftheinterest rate on the FRA.However, tounderstandthepricingand calculationofvalueforanFRA, viewingthecontractasa
commitment tolendorborrowat a certain interest rate at afuturedateis
helpful
Thenotationfor FRAs is unique Thereare twonumbers associatedwithanFRA:

Example: Why the futures pricemustequal thespotpriceatexpiration
Supposethecurrent spotprice of silveris$4.65 Demonstrateby arbitragethat the

Answer:
Suppose thefuturespricewas$4.70 Wecould buy thesilveratthespotprice of

Suppose instead the futures pricewas$4.61 Nowwewouldbuy the silvercontract,
