Singapore Exchange Regulation (SGX RegCo) is consulting the public on proposed changes to reduce the standard board lot size of certain instruments traded on SGX’s stock market.

This reduction was supported by the Equities Market Review Group as part of its recommendations to strengthen the development of Singapore’s stock market.

The proposed changes are:

1. reduction in the standard board lot size from 100 units to 10 units for instruments priced above $10 and up to $100; and
2. reduction in the standard board lot size from 100 units to 1 unit for instruments priced above $100.

A smaller standard board lot size will lower the minimum outlay required for investments. This makes higher-priced stocks more affordable and accessible to investors, which could in turn broaden investor participation and increase trading activity. 

“Share prices of some of our largest stocks have risen significantly in recent years, and about 30% of trading activity now comes from stocks priced above $10. This is the segment where we want to enhance accessibility and broaden participation. By reducing the board lot size for these higher-priced stocks, we bring the minimum investment down from a few thousand dollars to just a few hundred – making such investments more within reach, especially for younger retail investors,” said Ng Yao Loong, Head of Equities, SGX Group.

Separately, arising from a regular review of the stock market structure, SGX RegCo is also proposing to remove the requirement to align the minimum bid sizes of securities and futures contracts traded in Hong Kong Dollar, Renminbi or Japanese Yen to those in their home markets.

The consultation is found here and SGX RegCo requests all comments by 13 February 2026. If the market supports the changes, they are expected to be implemented in mid-2026.
