SGX cuts board lots for 11 stocks as new order-size rule takes effect
The initial 11 stocks move from 100-unit to 10-unit lots on 5 October. Existing holdings stay unchanged, while brokers specify pending-order handling.
Singapore Exchange reduces the standard board lot for an initial 11 stocks from 100 units to 10 on 5 October, putting a previously announced market-structure rule into effect. The change affects the minimum unit grouping used for orders in those securities; it does not alter the number of shares investors already own.
The first group includes DBS, OCBC, UOB, Great Eastern, Haw Par, Jardine Cycle & Carriage, Jardine Matheson, Keppel, Prudential, Singapore Exchange and Venture Corporation. Broker Futu’s implementation guidance lists the affected securities and says they retain their existing stock codes.
Under the wider framework, qualifying instruments priced above 10 and up to 100 in their traded currency move to 10-unit lots, while those priced above 100 move to one-unit lots. Instruments at or below the lower threshold retain their existing lot size. The initial 11-stock change should therefore be distinguished from a blanket reduction covering every SGX security.
The operational transition also affects standing orders. Futu’s guidance says all pending orders for the 11 affected stocks were to be cancelled after the close of business on Friday, 2 October, before the new lots took effect. That is the broker’s stated handling arrangement, rather than evidence that any particular customer’s order has been cancelled. It says existing holdings require no action.
SGX will review eligibility every calendar quarter. The next review, in January 2027, will consider daily closing prices from July to December 2026. Changes are to be announced within the first five trading days after each quarter and implemented within the first five trading days of the second month following that quarter.
Once a security’s lot size has been reduced, the smaller lot remains even if its price subsequently falls below the relevant threshold. This makes the published lot assignment, rather than a single day’s share price, the relevant check for order sizing.
The initial 11 stocks accounted for 35% of trading activity in the first half of 2026, according to SGX’s July announcement. That historical share establishes the scope of the affected group; it is not a measure of trading activity after implementation. SGX expects smaller lots to improve affordability, but the effective-date announcement does not demonstrate increased liquidity or investor participation.
