The Hong Kong Monetary Authority (HKMA) is the central banking institution of Hong Kong, responsible for maintaining monetary stability and ensuring the safety and integrity of the financial system. In the context of sanctions and financial crime compliance, HKMA plays a crucial role in implementing anti-money laundering (AML) and counter-terrorism financing (CTF) measures. 

HKMA provides regulatory guidance to financial institutions, mandating them to conduct thorough customer due diligence, monitor transactions, and report suspicious activities. The authority also oversees compliance with international sanctions, ensuring that Hong Kong adheres to global standards and obligations. Through its supervisory framework, HKMA aims to mitigate risks associated with financial crime and maintain the robustness of Hong Kong’s financial markets. By promoting a strong compliance culture among banks and other financial entities, HKMA helps safeguard the region's reputation as a leading international financial centre.
