The Monetary Authority of Singapore (MAS) is Singapore’s central bank and financial regulatory authority, responsible for promoting a stable and efficient financial system. In the context of sanctions and financial crime compliance, MAS plays a vital role in overseeing the implementation of anti-money laundering (AML) and counter-terrorism financing (CTF) regulations. 

MAS develops and enforces comprehensive regulatory frameworks that require financial institutions to conduct thorough due diligence, monitor transactions, and report suspicious activities. The authority also maintains sanctions lists that align with international obligations, guiding businesses on compliance with both domestic and international sanctions regimes. Through its supervision and guidance, MAS aims to mitigate risks associated with financial crime, enhance the integrity of Singapore's financial sector, and ensure compliance with global standards. The proactive stance taken by MAS reinforces Singapore’s reputation as a robust and transparent financial hub in the Asia-Pacific region.
