Second, on 9 March 2026, MAS and Police jointly conducted enforcement operations against Capital Asia Investments Pte Ltd and its directors for suspected money laundering under Section 54 of the Corruption, Drug Trafficking and Other Serious Crimes Act and suspected non-compliance with obligations as a licensed capital markets services licence holder under the Financial Services and Markets Act 2022. Third, on 17 March 2026, MAS issued a 16-year Prohibition Order against Mr Wang Qiming and a 7-year Prohibition Order against Mr Liu Kai, former relationship managers convicted of charges connected to the major money laundering case of August 2023.

Fund managers, licensed capital markets services licence holders, and financial institutions should review their anti-money laundering controls and investor protection practices. Individuals subject to Prohibition Orders must immediately cease all activities requiring MAS authorization. Firms should monitor MAS enforcement publications for additional actions related to the August 2023 money laundering case. MAS has indicated it takes enforcement actions to deter misconduct and safeguard Singapore's integrity as a financial centre.

What to do next

Review and strengthen anti-money laundering controls and transaction monitoring systems
Ensure compliance with capital markets services licence obligations under FSMA 2022
Screen personnel against prohibition order records to ensure no prohibited individuals hold key roles

Penalties

Prohibition Orders bar individuals from carrying on any regulated activity in Singapore. Joint MAS-Police enforcement may result in criminal prosecution for money laundering offences under CDSA.
