大約23如果季計(jì)復(fù)利，且以實(shí)際/360計(jì)算天數(shù)，則利率為4.8%；如果以實(shí)際/實(shí)際計(jì)算天數(shù)，那么利率變成:4.8%*365/360=4.867%;如果以連續(xù)復(fù)利計(jì)算，那么利率變成：4ln(1+0.4867/4)=4.84%.因此，以連續(xù)復(fù)利計(jì)算的遠(yuǎn)期利率為4.84-0.23=4.61%。ThetreasurershouldshortTreasurybondfuturescontract.Ifbondpricesgodown,thisfuturespositionwillprovideoffsettinggains.Thenumberofcontractsthatshouldbeshortedis10,000,000×7.1/(91,375×8.8)=Roundingtothenearestwholenumber88contractsshouldbeTheEurodollarfuturescontractpriceof89.5meansthattheEurodollarfuturesrateis10.5%perannumwithquarterlycompoundingandanactual/360daycount.This es10.5×365/360=10.646%withanactual/actualdayThisis：41n(1+0.25×0.10646)=0.1051or10.51%withcontinuousTheforwardrategivenbythe91-dayrateandthe182-dayrateis10.4%withcompounding.ThissuggeststhefollowingarbitrageBuyEurodollarBorrow182-day3.Investtheborrowedmoneyfor914個(gè)月后收到6百萬(wàn)并支付4.80百萬(wàn)。10個(gè)月后將收到6百萬(wàn)并支付4個(gè)月對(duì)于支付浮動(dòng)利率的一方而言，互換的價(jià)值為103.328-101.364=1.964百萬(wàn)。對(duì)于支付1.11/
