Why Did The HKD Finally Move?

Thursday, for the first time in over a week, HKD moved. That’s not unsurprising, as we should expect that nothing goes in a straight line – even devaluation of this kind. The issue is more about why it might have moved, or what it cost to move it.

The Hong Kong Monetary Authority (HKMA) had started carefully. They were only buying HKD in small amounts at first. This week, however, they stepped up their operations. Through April 18, HKMA had sold $4.3 billion in US$ reserves, half of that total on the 17th and 18th alone. Thursday, the monetary board acting now as de facto central bank has sold $2.2 billion more.
