问题如下：
Which of the following is most likely the result from a policy rate increase?
选项：
A. The investment in new projects is increasing.
B. Consumers are more preferred to credit purchases.
C. The domestic currency is more valuable relative to foreign currency.
解释：
C is correct.
A rise in policy rates increases the bank’s lending rate in the short-run. Investors feel expensive to borrow and make new investment. Consumers will reduce credit purchases. However, a higher yield will attract foreign investment and strength the domestic currency correspondingly.
考点：policy rates
解析：政策利率的上升在短期内会提高银行的贷款利率。投资者觉得借钱和进行新投资的成本上升而减少投资。A选项错误。
消费者也将减少信贷购买。所以B选项错误。
然而，较高的收益率将吸引外国投资，并相应地使本币走强。所以C选项正确。
为什么同一措施会让国内国外不同？：C.让投资收益率上升，吸引国外投资。A. 国内投资减少
