Contents
01 · Executive Summary
Context/The Framework/Building Blocks 1 & 2/Building Blocks 3 & 4/The Opportunity/Implementation
Singapore has the foundations to lead tokenised capital markets in Asia, and four building blocks would let it do so
Context
Tokenised settlement is moving into production abroad, and Singapore would gain at three levels by building it now
02 · The Format Shift
Context/The Framework/Building Blocks 1 & 2/Building Blocks 3 & 4/The Opportunity/Implementation
Capital markets are replacing electronic book entries with tokenised records, and Singapore can lead that change in its region
03 · The Global Race
Context/The Framework/Building Blocks 1 & 2/Building Blocks 3 & 4/The Opportunity/Implementation
Market infrastructures abroad are building tokenised settlement now, and their designs point to one architecture
04 · The Market Vision
Context/The Framework/Building Blocks 1 & 2/Building Blocks 3 & 4/The Opportunity/Implementation
Singapore could gain at three levels, from its home market to global capital, and each gain needs infrastructure built now
The Framework
Four building blocks would make up the framework, with digital money at the base
05 · Digital Money as Foundation
Context/The Framework/Building Blocks 1 & 2/Building Blocks 3 & 4/The Opportunity/Implementation
Tokenised markets need digital money to settle, so the two must be designed and built together
06 · The Four Building Blocks
Context/The Framework/Building Blocks 1 & 2/Building Blocks 3 & 4/The Opportunity/Implementation
Four building blocks would form a complete tokenised capital market, and each requires the one beneath it
Building Blocks 1 & 2
MAS, the Ministry of Finance and the banks would provide digital money and tokenised SGS, the two blocks that the market cannot build alone
07 · Building Block 1: Digital Money (Local)
Context/The Framework/Building Blocks 1 & 2/Building Blocks 3 & 4/The Opportunity/Implementation
1 · Money2 · Collateral3 · Registry4 · Settlement
Digital money in Singapore would need two tiers, one for sovereign settlement and one for commercial settlement
08 · Building Block 1: Digital Money (Local)
Context/The Framework/Building Blocks 1 & 2/Building Blocks 3 & 4/The Opportunity/Implementation
1 · Money2 · Collateral3 · Registry4 · Settlement
Banks can close the digital money gap now, using the licences they already hold
09 · Building Block 1: Digital Money (Regional and International)
Context/The Framework/Building Blocks 1 & 2/Building Blocks 3 & 4/The Opportunity/Implementation
1 · Money2 · Collateral3 · Registry4 · Settlement
Singapore could export the framework for digital money, and each ASEAN country would issue its own currency on the shared infrastructure
10 · Building Block 2: Tokenised Risk-Free Collateral (Local)
Context/The Framework/Building Blocks 1 & 2/Building Blocks 3 & 4/The Opportunity/Implementation
1 · Money2 · Collateral3 · Registry4 · Settlement
Tokenised SGS would be the risk-free asset of Singapore's tokenised market and its most consequential piece of infrastructure
11 · Building Block 2: Tokenised Risk-Free Collateral (Local)
Context/The Framework/Building Blocks 1 & 2/Building Blocks 3 & 4/The Opportunity/Implementation
1 · Money2 · Collateral3 · Registry4 · Settlement
Moving collateral in real time would bring the largest early gain, and one day of shorter settlement released USD 3 billion of margin in the US
12 · Building Block 2: Tokenised Risk-Free Collateral (Regional and International)
Context/The Framework/Building Blocks 1 & 2/Building Blocks 3 & 4/The Opportunity/Implementation
1 · Money2 · Collateral3 · Registry4 · Settlement
Tokenised SGS would also be Singapore's most exportable infrastructure, because ASEAN sovereigns could copy it and international collateral could connect to it
Building Blocks 3 & 4
We propose building the registry and settlement infrastructure on Canton, while keeping the option to move to another network
13 · Building Block 3: Digital Issuance and Registry Infrastructure (Local)
Context/The Framework/Building Blocks 1 & 2/Building Blocks 3 & 4/The Opportunity/Implementation
1 · Money2 · Collateral3 · Registry4 · Settlement
Canton is the most defensible network for Singapore's digital securities infrastructure, because the institutions Singapore needs to reach already use it
14 · Building Block 3: Digital Issuance and Registry Infrastructure (Local)
Context/The Framework/Building Blocks 1 & 2/Building Blocks 3 & 4/The Opportunity/Implementation
1 · Money2 · Collateral3 · Registry4 · Settlement
We propose committing to Canton while keeping the framework portable in case network conditions change
15 · How Canton Connects the Stack
Context/The Framework/Building Blocks 1 & 2/Building Blocks 3 & 4/The Opportunity/Implementation
1 · Money2 · Collateral3 · Registry4 · Settlement
On Canton, Singapore would sit on the same network as DTCC and Euroclear from launch, and markets that join later would have to catch up
Local MAS · SGX · CDP (illustrative)
  • SGD digital money: wholesale CBDC and tokenised deposits
  • Tokenised SGS: sovereign collateral
  • CDP digital registry track
  • SGX: primary market and listings
Canton Network The common settlement layer
  • Money Wholesale CBDC and tokenised deposits settle atomically
  • Collateral SGS and US Treasuries movable in real time
  • Securities Bonds, sukuk, carbon, private credit
  • Settlement Atomic DvP, programmable repo
International DTCC · Euroclear
  • DTCC & Euroclear as Canton Foundation co-chairs
  • SGX securities on the same network as US and European settlement infrastructure
  • Direct access to international institutional liquidity
Regional ASEAN exchanges
  • ASEAN exchange participants on shared infrastructure
  • Edge-market asset classes: bonds, sukuk, carbon, private credit
  • Cross-border issuance and shared collateral
Local control, regional liquidity and global capital access would all connect through the same network.
16 · Building Block 3: Digital Issuance and Registry Infrastructure (Regional)
Context/The Framework/Building Blocks 1 & 2/Building Blocks 3 & 4/The Opportunity/Implementation
1 · Money2 · Collateral3 · Registry4 · Settlement
Regional trading links have stalled for want of shared post-trade infrastructure, and the framework would build it
17 · Building Block 3: Digital Issuance and Registry Infrastructure (Regional)
Context/The Framework/Building Blocks 1 & 2/Building Blocks 3 & 4/The Opportunity/Implementation
1 · Money2 · Collateral3 · Registry4 · Settlement
Every ASEAN participant would keep local control, because no single party would own the network
18 · Building Block 3: Digital Issuance and Registry Infrastructure (Regional and International)
Context/The Framework/Building Blocks 1 & 2/Building Blocks 3 & 4/The Opportunity/Implementation
1 · Money2 · Collateral3 · Registry4 · Settlement
The framework would start in asset classes where ASEAN has yet to build registry infrastructure, with links to international settlement from launch
19 · Building Block 4: Trading, Clearing and Settlement Infrastructure (Local)
Context/The Framework/Building Blocks 1 & 2/Building Blocks 3 & 4/The Opportunity/Implementation
1 · Money2 · Collateral3 · Registry4 · Settlement
A dual-track market would keep liquidity together during the move to atomic settlement, and off-ledger business logic would keep the system portable
The Opportunity
Singapore could build the shared infrastructure that ASEAN markets lack and own it, as Nasdaq and Intercontinental Exchange (ICE) own theirs
20 · The ASEAN Opportunity
Context/The Framework/Building Blocks 1 & 2/Building Blocks 3 & 4/The Opportunity/Implementation
Singapore could fill the gap in ASEAN by exporting a complete stack that it would first prove in its own market
21 · The ASEAN Opportunity
Context/The Framework/Building Blocks 1 & 2/Building Blocks 3 & 4/The Opportunity/Implementation
Singapore's aim should be to own the infrastructure, which is how Nasdaq and ICE built revenue that outlasts listing cycles
22 · The Infrastructure Ownership Model
Context/The Framework/Building Blocks 1 & 2/Building Blocks 3 & 4/The Opportunity/Implementation
Each regional market would connect to infrastructure that Singapore builds and maintains, and no participant would control it alone
SGX · CDP · MAS (illustrative) First and primary user of the infrastructure
Singapore Infrastructure Layer
Digital Money
Tokenised Collateral
Issuance & Registry
Trading & Settlement
▶
DTCC
Euroclear
International
Indonesia
Malaysia
Thailand
Philippines
Vietnam
Hong Kong
Each market connects to the shared infrastructure as an equal participant.
Each connected market would issue on its own terms, clear on the shared infrastructure and reach international liquidity through infrastructure that Singapore builds and maintains. Governance would be decentralised, so no participant, Singapore included, could control the infrastructure alone.
Implementation
MAS, SGX, CDP and the banks could build all four blocks at once, starting from capabilities that exist today
23 · The Role of Banks
Context/The Framework/Building Blocks 1 & 2/Building Blocks 3 & 4/The Opportunity/Implementation
Banks would keep their core functions in tokenised markets and could earn from several new services
24 · Sequencing and Concurrency
Context/The Framework/Building Blocks 1 & 2/Building Blocks 3 & 4/The Opportunity/Implementation
The building blocks depend on one another in a fixed order, and all four can still be built at the same time
25 · Coordination Across the Parties
Context/The Framework/Building Blocks 1 & 2/Building Blocks 3 & 4/The Opportunity/Implementation
Each party would hold decisions that only it can take, so the framework needs all of them to act
Primary decision Supporting role
MAS Wholesale CBDC in production, a tokenised SGS issuance programme and the regulatory perimeter for digital securities Standards body for ASEAN adoption and bilateral discussions on legal equivalence
SGX and CDP Dual-track market infrastructure, integration with Canton and DTCC, and a digital registry alongside existing CDP infrastructure Primary market infrastructure for tokenised securities and connections for regional exchanges through shared settlement infrastructure
Banks Tokenised deposit infrastructure for settlement, custody of institutional digital assets and collateral management across platforms Issuance agency and trusteeship, and market-making in tokenised secondary markets
MAS and banks jointly Regulated SGD stablecoin framework brought into law and into operation Tokenised interbank settlement networks, including Partior, connected to the settlement layer on Canton
26 · From Framework to Production
Context/The Framework/Building Blocks 1 & 2/Building Blocks 3 & 4/The Opportunity/Implementation
Three capabilities could be ready for production-equivalent testing within 12 to 18 months of a decision to build them
27 · Where Movement Is Needed
Context/The Framework/Building Blocks 1 & 2/Building Blocks 3 & 4/The Opportunity/Implementation
Four decisions would move the framework forward, and progress on any one would help the others

Three of the four already have a technical base in Singapore: the SGD Testnet, live tokenised deposits at DBS, OCBC and UOB, and MAS's planned trial of tokenised MAS Bills.9, 10

Singapore could lead the next era of Asian capital markets, and this framework sets out one considered way to get there.

1Wholesale CBDC. Wholesale central bank digital currency: central bank money in digital form, issued only to regulated financial institutions for settlement between them. A retail CBDC would be issued to the public.
2SNB, Project Helvetia. The SNB has issued wholesale CBDC on the SIX Digital Exchange platform since 1 December 2023. In June 2025 it extended the pilot to at least June 2027, and it states that the pilot is no commitment to issue wholesale CBDC permanently. Source: SNB, Project Helvetia, snb.ch.
3Nasdaq. The SEC approved rule change SR-NASDAQ-2025-072 on 18 March 2026. Tokenised and traditional shares would share a CUSIP, symbol, order book and shareholder rights.

Food for Thought
Atomic settlement raises three questions about Singapore's post-trade system that are easier to resolve early
CDP's role under atomic settlement · The practical case for tokenised SGS · How interbank settlement could work
Question 1
CDP's role under atomic settlement
29 · Post-Trade in a Tokenised Market
Atomic settlement would gradually take over both of CDP's clearing functions, so Singapore should decide early where netting will sit
Both questions, where netting sits and what role underpins CDP, are easier to answer early, while Singapore still controls the timing.
Question 2
The practical case for tokenised SGS
30 · SGS and US Treasuries
Singapore must judge tokenised SGS on the facts of its own market, which differ sharply from the US Treasury market
31 · Collateral Velocity
Tokenised SGS could turn a static liquidity buffer into working collateral, and each extra use of a limited supply would be worth more
32 · SGS Repo Market
Singapore's SGS repo market remains shallow mainly because each trade costs too much at current volumes, and tokenisation could cut that cost
33 · Three Stages of Value
Tokenised SGS could deliver value in three stages, each building on the one before

These stages describe what could happen, and each would follow only if participants find enough commercial value in the one before.

Question 3
How interbank settlement could work
34 · Settlement Scenarios
The seller would receive funds through its bank, by a path that depends on whether buyer and seller use the same bank
35 · Netting Migration
Interbank netting would take over from CDP's multilateral netting, so the operation would continue in a new place
36 · Batch to Continuous Settlement
Intraday batches are the realistic near-term step, and each shorter batch window would move more netting from CDP to the banks
Stage Settlement model Where netting sits
Stage 1 (near term) Trades would settle in one end-of-day batch, netted and settled atomically at the close. CDP would keep its netting role, and banks would settle net interbank positions once a day.
Stage 2 (medium term) Trades would settle in two to four intraday batches, with less netting in each smaller batch. CDP's netting would release less capital as batches shrink.
Stage 3 (potential end state) Each trade would settle atomically as it matches, and securities would move gross. Banks would net interbank cash on their own cycle, and CDP's netting would end in its current form.
At every stage, the seller would receive funds promptly, either by book entry within one bank or by its bank's advance credit against a verified commitment. The interbank cycle would decide only when the credit exposure between banks clears.
