Singapore MPI vs SPI: Which Crypto Licence? (2026)

Both are Singapore Payment Services Act licences for Digital Payment Token services under MAS — a Standard Payment Institution (SPI, S$100,000 base capital) caps transaction volumes, while a Major Payment Institution (MPI, S$250,000) removes them. If you are licensing a crypto business in Singapore, the first real decision is not which lawyer or which bank — it is which class of licence you are applying for. The Monetary Authority of Singapore issues two, and the phrase you keep hitting is “Singapore MPI vs SPI”. Pick the wrong one and you either over-capitalise a small operation or, far more damaging, outgrow your licence and have to re-file mid-growth under regulatory pressure.

In our practice, the operators who get this right decide the tier from their volumes, not from the sticker price of the capital. The Standard Payment Institution looks cheaper on day one, but for anyone building an exchange or a payments business with real ambition, the Major Payment Institution is usually the licence you actually need. This guide sets out exactly how the two DPT classes differ under the Payment Services Act — the thresholds, the capital, the safeguarding — and how to tell which one your business falls into.

The two DPT licence classes under the Payment Services Act

Digital Payment Token services in Singapore are not licensed under a bespoke “crypto law”. They sit inside the Payment Services Act 2019 (PS Act), the same framework that governs account issuance, domestic and cross-border money transfers, merchant acquisition and e-money. MAS treats buying, selling and dealing in tokens like Bitcoin or Ether — and facilitating their exchange — as a regulated payment activity called DPT service. That framing is the key to understanding the two tiers, because the licence classes come from the payments world, not from crypto.

Under the PS Act, MAS grants three classes of payment-institution licence: Money-Changing (narrow, and not the crypto route), Standard Payment Institution (SPI) and Major Payment Institution (MPI). For a crypto business the choice is binary — SPI or MPI. Both authorise the same DPT activity, both require a Singapore company with a permanent place of business and a resident executive director, and both sit under full MAS AML/CFT, technology-risk and user-protection supervision. What separates them is a single question: how big is your operation, measured by transaction volume and the float you hold?

That is the entire logic of the split. The SPI is the entry tier for firms below defined limits; the MPI is the tier for everyone at or above them. Because the activity is identical, the licence you need is decided by the numbers — the thresholds, not the capital figures, are the thing to understand first. For the full picture, our Singapore crypto licence pillar covers the whole DPT framework end to end.

How the SPI thresholds actually work

An SPI is only available while your business stays below MAS’s ceilings — and it is not one number, it is a set of limits you must satisfy simultaneously. For DPT services the two that matter are a monthly transaction limit and a daily float limit.

The monthly DPT transaction threshold is S$3 million — the average monthly value of all DPT transactions you process, measured over a calendar year. The daily e-money float threshold is S$5 million — the average daily total of e-money you hold on behalf of customers. There is also an overarching combined limit of S$6 million per month across all payment services for an SPI. Stay under all of these and you qualify for a Standard Payment Institution licence; breach any one and MAS expects you on the Major Payment Institution track.

Two subtleties trip operators up. First, the tests are on averages, so a single spike does not automatically demote you — but a sustained trend across the year does. Second, and more important, MAS assesses this prospectively: if your business plan and projections show you crossing S$3 million in monthly DPT volume, MAS will steer you to an MPI from the outset. The threshold is a forecast question as much as a historical one.

Capital and safeguarding: where SPI and MPI really diverge

The headline numbers are simple: an SPI holds S$100,000 base capital and an MPI holds S$250,000. But base capital is the floor, and the real difference between the two licences shows up in what MAS layers on top of it.

For an MPI, MAS applies risk-based capital buffers and — critically — a safeguarding obligation on customer money and DPT float that has no equivalent at the SPI tier. An MPI must protect relevant assets it holds for customers through an approved mechanism (such as a bank guarantee or segregation with a safeguarding institution), which ties up real balance-sheet capacity beyond the S$250,000 headline. In practice, a serious MPI is capitalised and structured well above its base figure once safeguarding, operating capital and MAS’s buffers are counted together.

Everything else — the fit-and-proper director tests, the AML/CFT programme, technology-risk management, the appointed compliance and AML officer — applies to both tiers. Governance is not where the two licences differ; capital and safeguarding are. The Singapore figures are their own regime, not the flat tiers MiCA sets in Europe, so EU comparisons mislead — our CASP capital requirements guide shows how the European tiers contrast for anyone weighing both.

Why most serious crypto operators need an MPI

Read the thresholds against real trading volumes and the conclusion is usually clear. S$3 million in average monthly DPT transactions is roughly S$100,000 a day — a figure a functioning exchange, OTC desk or crypto-payments business clears quickly. For any operator with genuine scale ambitions, the SPI ceiling is not a comfortable headroom; it is a wall you hit early.

That is why, in our experience, the majority of firms building a real Singapore crypto business apply directly for an MPI. The MPI has no transaction or float cap, so it is the only tier that supports growth without a licensing event getting in the way. It is also the credential your banking and institutional counterparties expect — a Major Payment Institution licence signals to a bank, a custodian or a listing partner that you cleared MAS’s full-scale bar, safeguarding included. An SPI, by contrast, quietly tells a sophisticated counterparty that you are still below the thresholds.

The cost of getting this wrong is not just the extra capital. If you launch as an SPI and breach the threshold, you face a fresh MPI assessment — more capital, safeguarding to stand up, governance to deepen — under the time pressure of an operation already live and growing. Re-papering a licence while you trade is the expensive path. For most scaling operators the MPI is the efficient choice, not the cautious one, and our breakdown of the full Singapore crypto licence cost models both tiers before you commit.

When an SPI is genuinely enough

None of this means the SPI is a trap. It is a legitimate, useful licence for the right profile. If you are running a smaller or single-market DPT operation — a niche brokerage, a contained payments feature, a proof-of-concept with modest volumes and no near-term plan to cross S$3 million a month — the SPI lets you operate under MAS with lower base capital and without the full safeguarding build.

The honest test is your own forecast. If credible projections keep you under both thresholds for the foreseeable future, an SPI is the proportionate spend and there is no reason to over-capitalise. If the model shows you crossing the line inside a year or two, the SPI is a false economy — you pay to build it and pay again to upgrade it. Map your real DPT volumes and float against the ceilings, and let the numbers pick the tier.

The phased PS Act and DTSP amendments (Jul 2026 / Jan 2027)

One more factor belongs in any 2026 tier decision: the rules are moving. MAS is phasing in amendments to the Payment Services Act and the broader Digital Token Service Provider (DTSP) framework, and they raise the bar for both classes. Capital and governance changes land from July 2026, with full operational compliance from January 2027. The direction is consistent — more capital, tighter governance, firmer user-protection and safeguarding expectations.

For an applicant, the practical takeaway is to build to the incoming standard rather than the outgoing one. A file scoped only to today’s minimums can be out of date before the licence is even granted, given MAS’s realistic nine-to-fourteen-month processing timeline for a well-resourced application. By early 2026 MAS had granted roughly 30 MPI and over 60 SPI licences — a deep, active regime, but a deliberate and evidence-heavy one, and not a market where a thin application survives.

That is the whole case for deciding the tier deliberately. Choose SPI or MPI from your projected volumes, capitalise and safeguard for the version of the rules coming into force, and file once — properly — rather than twice under pressure.
