问题如下：
Until recently, Country A and Country B had similar interest rates. The central bank of Country A has just increased interest rates. A speculator thinks this will lead to international investors moving funds from Country B’s currency to Country A’s currency to earn the higher interest rate. This will increase the demand for currency A, and as a result, currency A will strengthen relative to currency B. What spot or forward trades should the speculator do?

解释：
The speculator thinks that currency A will strengthen. However, interest rate parity indicates that it is weaker in the forward market. If the speculator is right, he or she will make money by buying currency A with currency B in the spot market and then selling it on the delivery date.
t=0，speculator 借入B，买A，把A存银行赚高利息，对吗？
t=t, speculator取回A本息，买B还银行，是这样吗？
这样能套利吗？是不是要有前提条件，A的利率要超过AB的汇率才行呢？
谢谢老师。
