The Monetary Authority of Singapore's Single-Currency Stablecoin (SCS) framework is the production perimeter for fiat-backed stablecoin issuance from Singapore, restricted to single G10 currency designs and channelled through the Major Payment Institution (MPI) licensing layer under the Payment Services Act. The narrative summary lives in Stablecoin types Section 5.1; this page goes a layer deeper on the operational mechanics that determine whether a particular issuer can actually fit. Reserve composition rules, custody segregation, attestation cadence, the licensing perimeter, and the "MAS-regulated SCS" labelling mechanic each have specific operating implications, and the perimeter for foreign stablecoins distributed in Singapore (rather than issued from Singapore) is a separate question that the framework addresses obliquely. For an issuer choosing between Singapore, Hong Kong, the EU under MiCA, and the US under GENIUS, the SCS framework is the narrowest of the four perimeters, and the narrowness is deliberate.

What the framework actually covers

The SCS framework is a regulatory regime for single-currency stablecoins denominated in SGD or any G10 currency, issued by an entity licensed by MAS as a Major Payment Institution under the Payment Services Act. The framework is not a separate licence in its own right; it is a set of rules that overlay the MPI licence when the licensee is engaged in single-currency stablecoin issuance.

A few things drop out of that structure immediately. First, multi-currency basket designs are out of scope. The EU's asset-referenced token (ART) category under MiCA has no Singapore equivalent under the SCS framework, which means a basket-pegged stablecoin issuer cannot be MAS-regulated SCS, regardless of how the reserves are held. Second, non-G10 designs are out of scope: an emerging-markets-pegged stablecoin issued from Singapore would not fit, even with otherwise compliant reserves. Third, the framework does not authorise tokenised deposits, tokenised money-market funds, or any product that is not structurally a single-currency stablecoin. Those sit elsewhere in the regulated stack.

Fourth, and more subtly, the framework does not by itself solve the problem of cross-border issuance. An entity that wants to issue an SCS to non-Singapore-resident holders, or to distribute it through non-Singapore-licensed counterparties, has to address whatever target-jurisdiction perimeter applies in addition to the MAS perimeter. The SCS framework is a Singapore perimeter for a Singapore-issued instrument, not an EU-style passporting mechanism.

The MPI licensing layer

The licensing route runs through Part 3 of the Payment Services Act, with the relevant licence category being a Major Payment Institution licence with a specified payment service permission covering digital payment token services and, for stablecoin issuance specifically, the payment-instrument-issuance scope. An issuer cannot run an SCS under a Standard Payment Institution (SPI) licence, because the volume thresholds that distinguish SPI from MPI cut below where any meaningful stablecoin issuance lives. MPI is the load-bearing licence for SCS purposes.

Capital requirements layered onto the MPI licence include base capital floors, with stablecoin-specific add-ons that reflect the redemption-on-demand nature of the instrument. The exact figures move as MAS revises its parameter sets, so they are not worth quoting from memory; an issuer scoping the regime needs to read the operative MAS notices at the time of application. The structural point is that the capital regime is not the same as a bank's, and it is not intended to be: SCS issuance is a payments business with reserve and redemption obligations, not a deposit-taking business with maturity transformation.

A second structural point: the MPI is the issuer of record. The legal entity that holds the licence is the entity on the other side of the redemption right, not a sister entity, not a trust, not an offshore vehicle. This is operationally consequential, because it forecloses the kind of group-structure design where the licensed entity is a thin wrapper and the actual reserve management runs through an unlicensed affiliate. The regime is built to ensure that the entity supervised by MAS is the entity holding the obligation.

Reserve composition rules

Reserves backing an SCS must be held in cash, cash equivalents, or short-dated debt securities denominated in the same currency as the peg. The "same currency" leg is the constraint that bites first: a USD-pegged SCS issued from Singapore must hold USD reserves, not SGD reserves with an FX overlay. A SGD-pegged SCS holds SGD reserves. The framework does not allow the issuer to take FX risk between the reserve and the redemption obligation.

The reserve composition is constrained on duration as well as currency. Short-dated government securities (typically T-bills or equivalents in the pegged currency's home market) are eligible. Longer-duration government bonds are not. Corporate paper is not. Bank deposits at credit institutions of acceptable rating are eligible, with concentration limits to avoid single-bank dependence. Repo against high-quality liquid assets has been treated as eligible in the spirit of "cash equivalent" but the operative notice is the place to check the specific instrument list at the time of application.

The structural choice is the same one MiCA, GENIUS, and the Hong Kong Stablecoins Ordinance have made: keep the asset side narrow enough that the issuer cannot generate meaningful credit risk through reserve management, and rely on transparent attestation to make the narrowness verifiable. The Singapore-specific twist is the single-currency leg, which is more restrictive than Hong Kong's "fiat-referenced" framing and approximately as restrictive as the MiCA EMT regime for an equivalent single-currency design.

Custody segregation

Reserves must be held with an independent custodian rather than commingled on the issuer's own balance sheet. The independence requirement is the operating discipline that distinguishes the SCS framework from a model where the issuer simply holds the reserves on its own books and reports them.

Two consequences follow. First, the custodian is itself a regulated entity, typically a bank or a licensed trust company, which means the reserves benefit from the custodian's segregation regime as well as the issuer's. In a stress event affecting the issuer, the reserves should not form part of the issuer's general estate. Second, the custodian's operational reliability becomes part of the issuer's risk surface. An SCS issuer choosing a custodian is also choosing a counterparty whose operational outage can interrupt the redemption process even if the issuer is fully solvent.

The segregation model is similar in structure to the Hong Kong Stablecoins Ordinance custody requirement and to the GENIUS Act's bankruptcy-remote treatment, with the operative differences sitting in the specific custodian eligibility criteria. The MiCA EMT regime is broadly comparable but allows credit institutions to hold reserves directly under the EMI framework, with the consequence that some EU EMT issuers operate as their own reserve custodians under the umbrella of their banking or EMI licence.

Attestation cadence and depth

The SCS framework imposes monthly attestation as the regulatory floor. Monthly is also where MiCA, the Hong Kong Ordinance, and the US GENIUS framework have landed, so the SCS regime is in line with the global default rather than ahead of it. The differentiator, as discussed in Stablecoin types Section 2.1.1, is whether an individual issuer goes meaningfully beyond the floor.

The Singapore expectation has been that licensed issuers publish attestations from a recognised audit firm covering reserve composition at month-end, with the report identifying the custodian, the instrument breakdown, and any deviations from the eligibility rules. This is a closer-to-financial-statement-standard than some attestation regimes, because the expectation includes commentary on the issuer's redemption practice and operational metrics rather than a bare reserve snapshot.

Two operational notes for an issuer scoping the regime. First, the cadence required by the regulator is not the same as the cadence required by institutional counterparties. Some custodians and asset managers will require shorter cadence (weekly or daily reporting) before they will hold the SCS as a treasury instrument. Meeting the regulatory floor without exceeding it is a credible compliance posture but a weaker commercial one. Second, the on-chain near-real-time reserve disclosures that some newer issuers publish are a useful complement to monthly attestation but do not substitute for it under the SCS framework. The attestation is the load-bearing artefact for compliance purposes.

"MAS-regulated SCS" as a label

The framework includes a labelling mechanic that lets a licensed issuer represent its product as a "MAS-regulated stablecoin" or equivalent terminology, distinct from unregulated stablecoins circulating in the same market. The labelling is not just marketing. MAS has been clear that the use of any indicator suggesting MAS regulation is restricted to issuers that have actually obtained the licence and are operating within the SCS framework. Misuse of the labelling is itself a regulatory matter.

Two implications. First, the label is a meaningful commercial differentiator in a market where any number of unlicensed stablecoins can be advertised and used. An institutional counterparty (a bank holding the SCS as a payments instrument, an asset manager using it as cash collateral, a corporate treasurer touching it for cross-border movement) can credibly point to the MAS regime as the basis for its risk assessment. Without the label, the same instrument is harder to fit through a treasury policy review.

Second, the label restricts what foreign-issued stablecoins can claim when distributed in Singapore. An offshore USD stablecoin is not "MAS-regulated" by virtue of being available to Singapore residents; it remains an unregulated stablecoin from the perspective of the framework, with whatever distribution-perimeter rules MAS applies separately under the Payment Services Act and the broader DPT regime.

Non-SGD G10 issuance from Singapore

The framework explicitly contemplates issuance of SCS denominated in any G10 currency from a MAS-licensed entity. This is more permissive than a regime that restricts issuance to the home currency, and it is what makes Singapore a candidate venue for a USD-pegged or JPY-pegged or AUD-pegged SCS issued by a Singapore-licensed entity rather than from the home jurisdiction of the pegged currency.

The operating tradeoff is that a Singapore-issued non-SGD SCS is a Singapore-regulated instrument with reserves held in the pegged currency. From a holder's perspective, this is a non-trivial proposition: the issuer answers to MAS, the reserve custody runs under Singapore segregation rules, but the redemption obligation is denominated in a foreign currency held in foreign-currency accounts. The structure can work, and several commercial designs have explored it, but it is structurally different from a domestic regulator licensing a domestic-currency stablecoin.

A second consideration: non-SGD G10 issuance from Singapore competes directly with domestic regimes in the home currency's own jurisdiction. A USD-pegged SCS issued from Singapore is in the same product space as a US-domiciled GENIUS-regulated payment stablecoin, and the buyer choice between the two is partly a regulator-quality question and partly a distribution-and-licensing question. The Singapore route makes sense where the issuer wants Singapore as the operational hub and is willing to absorb the cross-border friction; otherwise the home-jurisdiction regime is usually the simpler route.

Foreign stablecoins distributed in Singapore

The SCS framework is an issuance regime, not a distribution regime. The question of whether a foreign stablecoin (USDC, USDT, a MiCA-EMT, a GENIUS-licensed product, a Hong Kong-licensed HKD stablecoin) can be distributed in Singapore is governed separately, primarily under the Payment Services Act's digital payment token (DPT) regime and the conduct rules MAS has imposed on DPT services.

The high-level posture: foreign stablecoins are not banned from circulation in Singapore, but they are not "MAS-regulated SCS" either. A DPT service provider distributing foreign stablecoins to Singapore retail or institutional users operates under the DPT licence, with associated conduct, custody, and disclosure obligations, but the underlying instrument carries whatever regulatory status it has from its home jurisdiction. From a counterparty's perspective, the differentiation is sharp: a Singapore-issued SCS under the framework benefits from the labelling and the MAS regime; a foreign stablecoin distributed in Singapore through a DPT service does not.

The cross-border consequence is that the SCS framework, on its own, does not produce a unified Singapore stablecoin perimeter. Rather, it sits alongside the DPT regime and (for offshore-served services) the DTSP regime. Reading the three together is the only way to get the full operating picture.

Comparison with Hong Kong, MiCA EMT, and GENIUS

A useful operator-grade comparison lives along four axes: scope, reserve constraints, attestation, and labelling.

On scope, the SCS framework is the narrowest of the four. Single-currency G10 only, with explicit exclusion of basket designs. The Hong Kong Stablecoins Ordinance covers a broader fiat-referenced perimeter (including the offshore renminbi corridor that gives Hong Kong a structurally different opportunity). MiCA splits into EMT (single-currency, similar to SCS) and ART (multi-currency basket, no SCS analogue). GENIUS in the US is restricted to USD-pegged payment stablecoins.

On reserve constraints, the four converge: cash, cash equivalents, short-dated government securities in the pegged currency, with limited bank-deposit and repo allowances. The differences are at the margin (which specific securities, what concentration limits) rather than at the structural level.

On attestation, all four impose monthly as the floor. Singapore matches the global default rather than leading.

On labelling, the SCS framework is the most explicit of the four about a regulatory brand. MiCA's EMT label is a category, not a marketing brand. GENIUS does not establish a comparable label. Hong Kong's Ordinance establishes a licensing perimeter without a comparable marketing instrument. The "MAS-regulated SCS" label is a deliberate Singapore policy choice, and is part of why Singapore-issued products have a stronger commercial differentiator than the underlying technical regime alone would suggest.

Open questions

• The list of MAS-regulated SCS issuers in production as of late 2025, and which currencies they cover. The framework was finalised in August 2023 and the licensing pipeline has run for some time, but a comprehensive public roster is not surfaced consistently.
• Whether MAS will add specific guidance on tokenised-deposit-versus-SCS demarcation, given that the underlying use cases overlap substantially in payments contexts. The framework as currently published does not heavily address that boundary.
• Whether the framework will be revised to admit non-G10 SCS designs (for example, an INR or IDR-pegged design issued from Singapore), or whether the G10 limit is structural and durable.
• The interaction between the SCS framework and any future MAS work on programmable purpose-bound money, which currently sits in Project Guardian rather than in the SCS regime.
