What was changed
Singapore's securities and futures exchanges were member-owned institutions when global exchanges were consolidating and electronic trading was spreading. In 1998, MAS convened a governance committee that recommended demutualising and merging SES and SIMEX.
The government accepted the recommendation, legislated the merger, and formed Singapore Exchange in December 1999. SGX listed on its own bourse in November 2000, opening membership beyond old seats and liberalising broker commissions.
A decade later, the finance minister described SGX as a different institution: more international, more product-diverse, and operating with a dual role as commercial exchange and frontline market regulator.
What it achieved
By 2009 SGX had over 760 listed companies, 40% from outside Singapore, and nearly half its revenue foreign-sourced.
Why it worked
The old mutual structure tied ownership to trading rights and slowed competitive responses.
A single securities-and-derivatives operator could build products and clearing infrastructure at scale.
A public listing made the exchange itself accountable to investors and disclosure rules.
What can be applied
Market infrastructure can be made more competitive by separating ownership from access and putting the operator under market discipline.
Aftermath
SGX became a regional listing, derivatives and clearing venue rather than a closed domestic club. The reform did not remove public oversight; MAS kept statutory supervision while SGX carried frontline responsibilities for a larger, more international market.
