1 MIN READ- The SGX will reduce standard board lot sizes effective October 5, 2026, to improve retail investor affordability.

The Singapore Exchange (SGX) is set to implement a major update to its trading rules, specifically focusing on the sgx board lot size reduction to enhance investor accessibility. Beginning October 5, 2026, the bourse will lower standard board lot requirements, significantly reducing the capital needed for retail investors to participate in the local equity market.
Improving Market Accessibility for Retail Investors
Currently, the high cost of entry for certain blue-chip stocks often deters smaller investors. Under the new policy, the standard board lot size will be slashed from 100 units to just 10 units for financial instruments priced between $10 and $100. For instruments valued above $100, the requirement will drop even further to a single unit. This sgx board lot size reduction is expected to foster greater market participation by removing traditional financial barriers.
The initial phase will impact 11 major stocks that were responsible for 35 percent of trading activity on the SGX during the first half of 2026. This list includes prominent entities such as DBS, OCBC, UOB, Keppel, Venture Corporation, and Great Eastern Holdings. The bourse has clarified that these reduced lot sizes will remain in effect even if the stock prices subsequently dip below the $10 or $100 thresholds.
To ensure ongoing relevance, the Singapore Exchange will conduct quarterly reviews of all instruments. Future adjustments will be determined based on daily closing prices, with announcements scheduled within five trading days following the end of each calendar quarter. The next review cycle is slated for January 2027, utilizing market data from the second half of 2026.
Enhancing Custody and Trading Standards
Beyond board lot changes, the bourse is introducing new measures regarding custody models. Effective July 15, 2026, SGX will allow depository agents to maintain securities in omnibus broker custody accounts. This move aligns local practices with global standards, aiming to attract more international intermediaries while offering investors greater flexibility. The regulatory arm, SGX RegCo, is also mandating minimum service standards to ensure shareholder rights, such as voting and participation in annual general meetings, are fully protected.
Additionally, the bourse is adjusting its bid mechanics for foreign-denominated securities. Starting July 15, the minimum bid sizes for contracts denominated in Hong Kong dollars, renminbi, and yen will no longer be pegged to their respective home market requirements. These comprehensive changes reflect a broader strategy to modernize the Singapore financial ecosystem, making it more efficient and investor-friendly as global trading practices continue to evolve.
