The Hong Kong dollar is pressed to the weak-side Convertibility Undertaking. What does the HKMA do?
A. It buys US dollars and sells Hong Kong dollars at 7.75
B. It lets the rate float beyond 7.85 and cuts the Base Rate on its own
C. It treats 7.85 as the strong side and injects HKD liquidity
D. It sells US dollars and buys Hong Kong dollars at 7.85, withdrawing HKD liquidity✓ 答案
解說
Weak side is 7.85: the HKMA sells USD and buys HKD, which withdraws Hong Kong dollar liquidity. Strong side is 7.75: the HKMA buys USD and sells HKD, injecting liquidity. The two sides must not be reversed, and the board does not float the rate.
