MAS Regulatory Framework Singapore: Guide for Investors
For informational purposes only — not financial advice.
The MAS regulatory framework encompasses laws and guidelines administered by the Monetary Authority of Singapore governing banks, capital markets, insurers, and fund managers. For investors, understanding MAS regulations helps verify broker legitimacy, understand S-REIT leverage rules, and know your investor rights under Singapore law.
What Is the Monetary Authority of Singapore (MAS)?
MAS is Singapore’s integrated central bank and financial regulator, established in 1971. It combines central banking (monetary policy, currency) with financial regulation (licensing, supervision, enforcement). MAS regulates all Singapore financial institutions: banks, insurers, brokers, fund managers, payment service providers, and REIT managers — maintaining financial stability, fair capital markets, and investor protection.
MAS Licensing: What to Look For as an Investor

How MAS Protects Singapore Investors
Key protections: (1) Client money segregation — licensed brokers keep client funds in separate trust accounts. (2) CDP registration — SGX securities in CDP accounts are legally yours, even if your broker fails. (3) Capital requirements — CMS licensees must maintain minimum financial resources reducing insolvency risk. (4) Accredited Investor framework — complex products restricted to AIs (net assets >S$2M or income >S$300K p.a.). (5) FIDReC — free dispute resolution for claims up to S$100,000.
How MAS Regulates S-REITs
S-REITs regulated under MAS Code on Collective Investment Schemes: 50% aggregate leverage cap, 1.5x minimum ICR (to borrow above 45%), 90% distribution requirement for tax-exempt status, mandatory REIT manager CMS licensing, and SGX quarterly/semi-annual reporting. These rules protect investors from excessive leverage and ensure income distribution to unitholders. Use our free S-REIT Gearing Ratio Calculator.
Frequently Asked Questions
What does MAS regulate in Singapore?
MAS regulates banks, insurers, brokers, fund managers, financial advisers, payment service providers, and financial exchanges. It sets licensing requirements, conduct standards, and prudential rules to protect investors and maintain financial stability.
How do I verify if a broker is MAS licensed?
Check the MAS Financial Institutions Directory at mas.gov.sg/financial-institutions. Only use brokers holding a valid Capital Markets Services (CMS) licence.
How does MAS protect investments if my broker goes bankrupt?
MAS requires client money to be segregated in trust accounts separate from the firm’s own funds. SGX securities held in CDP are legally owned by you — protected even in a broker insolvency.
What is the MAS gearing limit for S-REITs?
MAS caps S-REIT borrowings at 50% of total assets. REITs must also maintain a 1.5x ICR to borrow above 45% gearing — protecting investors from excessive debt risk.

An individual with net personal assets above S$2 million (or S$1 million in financial assets) or annual income above S$300,000. AIs access a wider product range but with fewer retail disclosure protections.
