假设你在报纸上看到以下金融数据： 英国政府债券的利率是每年6％，美国是7％，即期汇率是1．60美元=1

英镑。那么一年的远期汇率($US／￡)应是多少？美元相对于英镑是升水还是贴水？假如一年远期汇率与你的计算不同(比如说1．7美元=1英镑)，你能得到一个无风险的利润吗？为什么？ Suppose you read in the newspaper the following fmancial data： The interest rate on government bills in the United Kingdom is 6 percent per annum，and in the United States it is 7 percent per annum．The spot exchange rate is$US1．60=￡1．What should be the one-year forward exchange rate$US／￡？Is the dollar at a premium or a discount on the British pound？If the one-year forward exchange rate is different from the rate you calculated(say it is$US 1．70=￡1)，could you make a riskless profit？Why？
