Whydoesthisprocessoftenleadtothecreationofinterestraterisk?

Whatisinterestraterisk?

AssettransformationbyanFIinvolvespurchasingprimaryassetsandissuingsecondaryassetsasasourceoffunds.TheprimarysecuritiespurchasedbytheFIoftenhavematurityandliquiditycharacteristicsthataredifferentfromthesecondarysecuritiesissuedbytheFI.Forexample,abankbuysmedium-tolong-termbondsandmakesmedium-termloanswithfundsraisedbyissuingshort-termdeposits.

Interestrateriskoccursbecausethepricesandreinvestmentincomecharacteristicsoflong-termassetsreactdifferentlytochangesinmarketinterestratesthanthepricesandinterestexpensecharacteristicsofshort-termdeposits.Interestrateriskistheeffectonprices（value）andinterimcashflows（interestcouponpayment）causedbychangesinthelevelofinterestratesduringthelifeofthefinancialasset.

a.Whatwillbethenetinterestincome（NII）attheendofthefirstyear?

Note:

Netinterestincomeequalsinterestincomeminusinterestexpense.

Interestincome$1,000$10,000x0.10

Interestexpense600$10,000x0.06

Netinterestincome（NII）$400

b.Ifattheendofyear1marketinterestrateshaveincreased100basispoints（1percent）,whatwillbethenetinterestincomeforthesecondyear?

d.Ifmarketinterestrateshaddecreased100basispointsbytheendofyear1,wouldthemarketvalueofequitybehigherorlowerthan$1,000?

Why?

Themarketvalueoftheequitywouldbehigher（$1,600）becausethevalueofthebondwouldbehigher（$10,600）andthevalueoftheCDwouldremainunchanged.

e.Whatfactorshavecausedthechangeinoperatingperformanceandmarketvalueforthisfirm?

Theoperatingperformancehasbeenaffectedbythechangesinthemarketinterestratesthathavecausedthecorrespondingchangesininterestincome,interestexpense,andnetinterestincome.Thesespecificchangeshaveoccurredbecauseoftheuniquematuritiesofthefixed-rateassetsandfixed-rateliabilities.Similarly,theeconomicmarketvalueofthefirmhaschangedbecauseoftheeffectofthechangingratesonthemarketvalueofthebond.

Apolicyofmaturitymatchingwillallowchangesinmarketinterestratestohaveapproximatelythesameeffectonbothinterestincomeandinterestexpense.Anincreaseinrateswilltendtoincreasebothincomeandexpense,andadecreaseinrateswilltendtodecreasebothincomeandexpense.Thechangesinincomeandexpensemaynotbeequalbecauseofdifferentcashflowcharacteristicsoftheassetsandliabilities.Theasset-transformationfunctionofanFIinvolvesinvestingshort-termliabilitiesintolong-termassets.Maturitymatchingclearlyworksagainstsuccessfulimplementationofthisprocess.

Thatis,whichbond’spricewouldchangebyalargeramountforagivenchangeininterestrates?

Explainyouranswer.

Thezero-couponbondwouldhavemoreinterestraterisk.Becausetheentirecashflowisnotreceiveduntilthebondmatures,theentirecashflowisexposedtointerestratechangesovertheentirelifeofthebond.Thecashflowsofthecoupon-payingbondarereturnedwithperiodicregularity,thusallowinglessexposuretointerestratechanges.Ineffect,someofthecashflowsmaybereceivedbefore
