6、rbitrage conditions,we can safely assume that IRP holds.8Interest Rate Parity DefinedSuppose you have$100,000 to invest for one year.You can either 1.invest in the U.S.at i$.Future value=$100,000(1+ius)2.trade your dollars for yen at the spot rate,invest in Japan at i and hedge your exchange rate ri

7、sk by selling the future value of the Japanese investment forward.The future value=$100,000(F/S)(1+i)Since both of these investments have the same risk,they must have the same future valueotherwise an arbitrage would exist.(F/S)(1+i)=(1+ius)9Interest Rate Parity DefinedFormally,(F/S)(1+i)=(1+ius)or

8、if you prefer,IRP is sometimes approximated as 10IRP and Covered Interest ArbitrageIf IRP failed to hold,an arbitrage would exist.Its easiest to see this in the form of an example.Consider the following set of foreign and domestic interest rates and spot and forward exchange rates.Spot exchange rate

17、need to have an investment with a future value of 100 million.Since i=11.56%we need to invest 89.64 million at the start of the year.How many dollars will it take to acquire 89.64 million at the start of the year if S($/)=$1.25/?18Reasons for Deviations from IRPlTransactions CostsnThe interest rate

20、te of change in an exchange rate is equal to the differences in the rates of inflation.e=$-lIf U.S.inflation is 5%and U.K.inflation is 8%,the pound should depreciate by 3%.21PPP Deviations and the Real Exchange RateThe real exchange rate is If PPP holds,(1+e)=(1+$)/(1+),then q=1.If q 1 competitivene

22、 that is actively traded across borders.nShipping costs,as well as tariffs and quotas can lead to deviations from PPP.lPPP-determined exchange rates still provide a valuable benchmark.23The Fisher EffectslAn increase(decrease)in the expected rate of inflation will cause a proportionate increase(decr

28、Technical analysis looks for patterns in the past behavior of exchange rates.lClearly it is based upon the premise that history repeats itself.lThus it is at odds with the EMH31Performance of the ForecasterslForecasting is difficult,especially with regard to the future.lAs a whole,forecasters cannot

29、 do a better job of forecasting future exchange rates than the forward rate.lThe founder of Forbes Magazine once said:“You can make more money selling advice than following it.”32End Chapter Five331、有时候读书是一种巧妙地避开思考的方法。11月-2211月-22Monday,November 7,20222、阅读一切好书如同和过去最杰出的人谈话。20:23:2920:23:2920:2311/7/2
