SGX Operational Mechanics
A technical overview of the Singapore Exchange infrastructure, focusing on settlement cycles, account structures, and the evolution of trading accessibility for modern investors.
Standard Lot Size
In 2015, SGX reduced the standard board lot size from 1,000 to 100 units. This evolution significantly lowered the barrier to entry, allowing for more granular portfolio construction in high-priced blue-chip equities.
CDP Custody
The Central Depository (CDP) system provides a legal framework where securities are held directly in the investor's name. This direct ownership model offers a layer of protection distinct from nominee-based brokerage accounts.
Section 01
Trading Hours Evolution
The SGX has historically adjusted its operating hours to maximize overlap with other major Asian hubs. The current continuous trading session, introduced to replace the traditional mid-day break, ensures that price discovery remains uninterrupted during peak volatility periods in regional markets.
Modern traders benefit from Pre-Open and Pre-Close phases, which utilize a non-cancel period to establish fair opening and closing prices. Understanding these mechanics is vital for executing large orders without significant slippage.
Section 02
Lot Size & Market Access
The reduction of lot sizes to 100 units was a pivotal moment in the democratization of the Singapore stock market. Previously, high-value stocks required substantial capital outlays, effectively pricing out smaller investors from diversifying into top-tier Straits Times Index (STI) components.
This structural change has also facilitated the growth of the ETF market, as investors can now rebalance their portfolios with much higher precision. The shift mirrors global trends toward micro-investing and fractional ownership.
Infrastructure
CDP Account Structure & Legal Title
Individual Ownership
Unlike nominee accounts where the broker holds the shares on your behalf, a CDP account maintains the investor as the legal owner on the share register. This ensures that dividends, annual reports, and voting rights are managed directly between the issuer and the investor.
Systemic Integration
The CDP is integrated with the Monetary Authority of Singapore (MAS) regulatory framework. This centralization provides a consolidated view of all holdings across different brokerage platforms, simplifying tax reporting and estate planning. Learn more in our Regulatory Framework guide.
