As the HKD touched the Strong-side Convertibility Undertaking, the HKMA intervened the market and poured in funds. An HKMA spokesman remarked that the HKD was strong recently, mainly due to the increase in demand for HKD related to equity investment, which supported the HKD exchange rate. In addition, numerous regional currencies appreciated against the USD recently, which also contributed to the strengthening of the HKD. The last time the Strong-side Convertibility Undertaking was triggered was on October 28, 2020. The HKMA will continue to monitor market developments closely to ensure the orderly operation of the HKD market.
