On 1 July 2026, the Singapore Exchange (SGX) announced the reduction of standard board lot sizes for higher-priced stocks on 5 October 2026.

Board lot sizes

From 5 October 2026, the standard board lot size* will be reduced as proposed:
• From 100 units to 10 units for instruments priced above $10 and up to $100; and
• From 100 units to 1 unit for instruments priced above $100.

*Applicable for certain instruments including stocks (excluding preference shares), stapled securities, REITs, business trusts, company warrants excluding SPAC warrants, and depository receipts and depository shares that are listed on SGX-ST.

The initial reduction will take place for 11 stocks priced above S$10. These stocks accounted for 35% of trading activity in the first six months of this year. The board lot revision is thus expected to lower barriers to market participation and improve affordability for retail investors.

SGX will conduct a review every calendar quarter to determine if additional instruments qualify for a reduced board lot size. The next review following the October implementation will thus take place in January 2027. It will take into consideration daily close prices from July 2026 to December 2026.

Any changes to the board lot size will be announced within the first five trading days after the end of each calendar quarter and implemented within the first five trading days of the second month after the quarter.

Board lot size reductions will remain even if stocks fall below the $10 and $100 thresholds.
