Hong Kong Monetary Authority

The Hong Kong Monetary Authority (HKMA) is Hong Kong's monetary and banking authority. Established in 1993, it manages the Exchange Fund, operates the linked exchange-rate system, supervises authorised institutions and supports financial infrastructure. The Financial Secretary sets the monetary-policy objective; the Monetary Authority implements it.

Currency defence

The Hong Kong dollar operates through currency-board arrangements centred on a linked rate of HKD 7.80 per United States dollar, with convertibility undertakings at 7.75 and 7.85. Exchange Fund assets support the monetary base. The structure creates stability and close transmission of United States financial conditions.

In August 1998 the authorities bought Hong Kong equities and futures during the Asian financial crisis to counter a combined currency and equity attack. HKMA's contemporary annual report establishes the intervention and its rationale. The episode was exceptional and does not make equity purchase an ordinary currency-board tool.

Sanctions and payment infrastructure

HKMA's August 2020 circular distinguishes United Nations sanctions implemented in Hong Kong law from unilateral foreign sanctions, which do not themselves create Hong Kong legal obligations. Banks must still assess legal, business and commercial risks. Their customer decisions are not automatically HKMA orders.

HKMA has also participated in Project mBridge on cross-border central-bank digital currency infrastructure. The Bank for International Settlements reported minimum viable product status in 2024 and began an orderly transfer to the partner central banks during 2024-2025. The project should therefore not be described as currently BIS-led. Minimum viable product status does not establish mature general operation or a completed replacement for dollar clearing.

The institution's statecraft significance lies in defending monetary stability while managing exposure to competing legal and payment systems. Claims that HKMA can immunise banks from foreign secondary effects, or that mBridge proves de-dollarisation, exceed the evidence.
