A fund manager building a digital-asset strategy in Singapore quickly confronts a question that has real capital consequences: who holds the assets, under what authority, and does that custodian satisfy the regulatory expectations of the Monetary Authority of Singapore (MAS) under the Payment Services Act (PSA)? Getting the custody layer wrong does not simply create an operational headache. It can render the fund structure unsound from an investor-protection standpoint, delay institutional allocations, and expose the manager to MAS scrutiny before the first NAV is struck.
Custody of digital assets for funds in Singapore is a regulated activity. A service provider holding, controlling or safeguarding digital payment tokens (DPTs) on behalf of a fund is required to hold the appropriate authorisation under the MAS licensing regime. The practical implication is that fund managers – whether domiciling a vehicle under Singapore's Variable Capital Company (VCC) framework or using an offshore structure with a Singapore-licensed manager – must map the custody arrangement against that regime from day one, not as an afterthought at closing.
This page sets out the regulated basis for digital-asset custody in Singapore, the process for selecting and engaging a compliant custodian, the cross-border interaction with fund domicile and banking, and the decision points a fund manager should work through with counsel before committing to a structure.
What is the regulated basis for digital-asset custody in Singapore?
Custody of digital payment tokens for a third party is a regulated payment service under the MAS framework. A custodian must hold a licence under the Payment Services Act – specifically as a Major Payment Institution (MPI) if volumes exceed the thresholds MAS prescribes, or as a Standard Payment Institution (SPI) below them. Fund managers who self-custody on behalf of investors face the same analysis: if the arrangement amounts to holding DPTs on behalf of another person, it likely triggers a licensing requirement.
The PSA's digital payment token services category is deliberately broad. It covers not only custody in the traditional sense but also arrangements where a service provider controls the private keys, manages wallets on behalf of investors, or intermediates settlement. MAS has made clear, through supervisory guidance and public consultation, that investor-protection expectations in this space are equivalent in substance to those applied to traditional custodians: segregation of client assets, robust safeguarding of private keys, and documented operational controls.
For a fund, this has a structural implication. The fund's constitutional documents – whether a VCC sub-fund prospectus or a Cayman limited partnership agreement with Singapore-licensed management – must identify a custodian that holds or can obtain the requisite MAS authorisation. Institutional limited partners, particularly those subject to their own prudential rules, will conduct due diligence on that point before committing capital.
How does the Variable Capital Company framework interact with custody?
The Variable Capital Company (VCC) is Singapore's purpose-built collective investment vehicle, introduced under legislation administered by the Accounting and Corporate Regulatory Authority (ACRA) in coordination with MAS. A VCC must be managed by a holder of a Capital Markets Services (CMS) licence or a registered fund management company. The custody of assets held by a VCC sub-fund investing in digital assets must satisfy both the fund's constitutional requirements and the MAS DPT custody expectations.
In practice, this creates a two-track compliance obligation. First, the fund manager must hold, or be exempt from holding, a CMS licence for fund management. Second, the custodian holding the VCC's digital assets must hold the applicable PSA licence. These are separate authorisations from MAS, and neither substitutes for the other. We have seen structures collapse at due diligence precisely because the manager assumed its CMS licence covered the custody function – it does not.
A VCC investing primarily in DPTs typically requires a custodian that is independently licensed under the PSA and that has contractually committed to the segregation and safeguarding standards MAS expects. The VCC's prospectus and offering documents must disclose the custodian and describe the custody arrangement with sufficient particularity to satisfy MAS review.

How does a fund select and engage a compliant digital-asset custodian?
Selecting a custodian for a Singapore digital-asset fund is a structured process with legal, operational, and investor-relations dimensions, and it begins well before the fund launches.
The first step is confirming that the prospective custodian holds, or has applied for, the relevant PSA licence. MAS maintains a public register of licensed payment service providers. A custodian operating under an in-principle approval or an exemption for entities that filed a transitional notification is technically operating legally during the permitted period, but a fund accepting institutional capital should understand the residual risk of a custodian whose full licence is not yet finalised.
The second step is reviewing the custodian's operational framework. MAS expectations include: segregation of client assets from the custodian's proprietary assets; documented private key management and multi-signature controls; business continuity and disaster recovery provisions; and regular third-party audits. A fund manager conducting custodian due diligence should request the custodian's most recent audit report, its key management policy, and evidence of MAS-mandated AML/CFT controls under the applicable provisions of the regime.
The third step is negotiating the custody agreement itself. Standard terms for traditional securities custody do not translate cleanly to digital assets. Key negotiation points include: the treatment of hard forks and airdrops; the protocol for exercising governance rights; fee structures for staking-as-a-service if applicable; liability for private key loss or compromise; and the custodian's obligations in the event of its own insolvency. Singapore law on the property status of digital assets is continuing to develop, and counsel should advise on the contractual protections that supplement, not replace, the statutory framework.
The fourth step is disclosing the arrangement to investors. Offering documents must describe the custodian, the legal basis of the custody relationship, the material risks of digital-asset custody, and the steps the manager has taken to mitigate those risks. MAS has emphasised investor disclosure as a supervisory priority in the digital asset space.
What is the cross-border interaction between custody, fund domicile, and banking?
Very few digital-asset funds have all their moving parts in one jurisdiction. The manager may be Singapore-licensed, the fund vehicle may be domiciled in the Cayman Islands or BVI, the custodian may hold assets across several blockchains, and the investors may be institutional allocators in Europe, the Gulf, or North America. Each of those dimensions creates a legal and regulatory overlay that compounds the custody analysis.
On the domicile question: a Cayman or BVI fund vehicle using a Singapore-licensed manager does not automatically satisfy Singapore custody requirements. If the custodian is also offshore – a BVI FSC-registered VASP holding the assets, for instance – the fund manager must assess whether that arrangement satisfies MAS's expectations for the licensed management activity. MAS does not require that the custodian be Singapore-based, but it does expect the manager to demonstrate that the custody arrangements meet standards equivalent to those it would require of a locally licensed custodian. In our cross-border practice, we routinely advise managers on the comparative analysis between a Singapore PSA-licensed custodian and a Cayman or BVI alternative, including the investor-relations implications of each.
Banking interaction is the second cross-border pressure point. A Singapore digital-asset fund needs a banking relationship for fiat on-ramps, redemption payments, and treasury management. Singapore banks have been cautious about servicing digital-asset businesses, and a fund structure that does not clearly demonstrate a licensed custodian and a compliant manager framework is likely to encounter difficulties at account opening. The custodian relationship is, in effect, a banking pre-condition for many institutions – not a consequence of it.
On the tax side, Singapore imposes no capital gains tax and does not currently levy GST on the exchange of DPTs (following MAS's published guidance on the treatment of digital payment tokens for GST purposes). However, the treatment of income from staking, lending, or yield strategies within the fund requires separate analysis, and the fund's domicile affects the withholding and treaty position relevant to its investors. Operators we advise routinely find that the tax and custody decisions are more interdependent than they first appear: the asset mix affects the custody model, which affects the tax treatment, which affects which domicile produces the cleanest outcome for the target investor base.
If a prior application stalled or a banking relationship did not materialise, a structural review can identify the reason. Write to OBOLUS at info@oboluslaw.com to map the custody, banking and domicile stack for your fund.
What AML and Travel Rule obligations apply to a custodian holding fund assets?
A licensed DPT custodian in Singapore is a reporting entity under MAS's AML/CFT regime, which implements the Financial Action Task Force (FATF) standards, including Recommendation 15 on virtual assets. The Travel Rule – the obligation to pass originator and beneficiary information alongside a virtual asset transfer – applies to digital payment token transactions above the applicable threshold. A fund manager and its custodian must together map the points at which the Travel Rule is triggered and ensure the custodian's systems can generate and receive the required data.
For a fund, the Travel Rule creates a practical workflow question: when the fund redeems an investor's interest and the custodian transfers DPTs to the investor's wallet, who is the originator, who is the beneficiary, and what data passes with the transfer? The answer depends on the contractual structure of the custody arrangement and the technical capabilities of the custodian's compliance infrastructure. MAS has made Travel Rule compliance a supervisory focus, and a custodian that cannot demonstrate compliant data-passing procedures is a liability for the fund's own regulatory standing.
We advise managers to address the Travel Rule explicitly in the custodian selection process – not as a checkbox item in the custody agreement, but as a due diligence question with a technical answer. Regulators in the leading hubs increasingly expect that fund managers can describe, specifically, how Travel Rule data flows through their custody and transfer arrangements.
A custody restructure before launch
In a recent matter, a fund manager established under a Singapore CMS licence had engaged a custodian whose transitional PSA exemption was approaching expiry. The custodian's full licence application had not yet been approved. We assessed the structural risk for the manager's investor base – which included European institutional allocators subject to their own internal custody-counterparty policies – and identified that the arrangement would not satisfy those allocators' requirements at the next subscription date. Working with allied counsel in the relevant jurisdiction, we restructured the custody relationship, negotiated a parallel arrangement with a fully-licensed MPI custodian, and updated the fund's offering documents before the subscription window opened. The institutional close proceeded on schedule.
Which custody model fits which fund profile?
Not every digital-asset fund needs the same custody solution. The right model depends on the fund's asset mix, its investor base, its trading frequency, and its domicile.
A Singapore VCC investing primarily in liquid DPTs with institutional LP investors will typically require a Singapore MPI-licensed custodian with documented segregation, multi-signature key management, and the capacity to handle redemption-side Travel Rule obligations. The priority is investor-protection compliance and LP due diligence satisfiability. Timeline from custodian selection to executed custody agreement: typically several weeks, depending on negotiation complexity.
A Cayman-domiciled fund with a Singapore-licensed manager investing in a mix of DPTs and tokenised securities has more flexibility on custodian domicile, but the manager must document why the chosen custodian meets MAS-equivalent standards and must satisfy itself that the arrangement works for both the DPT and the tokenised-security assets. This profile often involves separate custody arrangements for different asset classes, which adds operational complexity and requires careful disclosure.
A smaller emerging-market fund manager testing the Singapore market with a sub-scale launch may consider a licensed SPI custodian rather than an MPI, provided volumes remain within the applicable thresholds. The risk is that growth beyond those thresholds requires migration to an MPI custodian mid-lifecycle, which carries operational and investor-relations cost. We generally advise managers to structure the custody arrangement to accommodate anticipated growth rather than current scale.
In each case, the custody arrangement must be disclosed in offering documents with sufficient specificity to satisfy MAS review and LP due diligence. The decision is not purely commercial; it has regulatory and investor-relations consequences that run through the life of the fund.
What are the most common custody mistakes Singapore fund managers make?
The most common mistake is treating custody as an operational decision rather than a legal and regulatory one. A fund manager that selects a custodian on the basis of technology and fee alone, without confirming the custodian's MAS licensing status and reviewing its operational controls, is creating a structural deficiency that will surface at LP due diligence or, worse, at a regulatory review.
A second common mistake is assuming that a CMS licence for fund management covers the custody function. It does not. The two licences are distinct, and a manager that holds assets on behalf of investors without either a PSA licence or a properly licensed third-party custodian is operating outside the permitted scope of its CMS authorisation.
A third mistake is neglecting the custody agreement's digital-asset-specific provisions. Standard institutional custody agreements are written for securities. They do not address hard forks, airdrops, governance participation, private key loss, or the insolvency treatment of digital assets. A fund that relies on a standard form without negotiating these provisions is exposed to disputes that Singapore courts may resolve in ways the parties did not anticipate.
A common assumption is that any offshore custody arrangement is acceptable as long as the fund is offshore. That assumption does not hold where the manager is Singapore-licensed. MAS looks through the fund structure to the manager's conduct, and a Singapore-licensed manager that directs assets to a non-compliant custodian may face supervisory action regardless of where the fund vehicle is incorporated.
Self-assessment checklist for fund managers
Before committing to a custody arrangement for a Singapore digital-asset fund, a manager should be able to answer yes to each of the following questions.
- Does the prospective custodian hold a current MAS PSA licence (MPI or SPI), or is its transitional exemption status documented and within its permitted period?
- Has the manager reviewed the custodian's most recent third-party audit report covering key management and AML/CFT controls?
- Does the custody agreement contain digital-asset-specific provisions addressing hard forks, airdrops, key loss liability, insolvency treatment, and Travel Rule data obligations?
- Are the custodian and the custody arrangement disclosed in the fund's offering documents with sufficient particularity to satisfy MAS review and LP due diligence?
- Has the manager confirmed that the custody arrangement satisfies the requirements of its target investor base, including any custodian-counterparty policies of institutional LPs?
- Is there a documented process for custodian migration if volumes breach the SPI/MPI threshold, or if the current custodian's licence lapses?
- Has the tax treatment of assets held in custody – including staking income, hard fork proceeds, and airdrop receipts – been reviewed in the context of the fund's domicile and investor base?
If the answer to any of these questions is uncertain, the custody arrangement needs further legal review before the fund accepts subscriptions.

FAQ
Where should a crypto fund be domiciled?
Domicile depends on the investor base, asset mix, tax profile and the manager's licensing jurisdiction. Singapore, Cayman, BVI and Malta each offer distinct advantages. A Singapore-domiciled VCC suits managers seeking a MAS-regulated vehicle with passporting optionality across the region. An offshore vehicle with a Singapore-licensed manager is common for institutional funds targeting global LP pools. The wrong domicile can create tax leakage and restrict which investor types the fund can accept – those consequences are structural and expensive to reverse.
Does a digital-asset fund manager need a licence?
In Singapore, a fund manager must hold a Capital Markets Services licence for fund management, or qualify for an applicable exemption, regardless of whether the assets are digital or traditional. Managing a collective investment scheme investing in DPTs does not escape the CMS licensing requirement. Additionally, if the manager itself holds or controls DPTs on behalf of investors, a Payment Services Act licence for DPT services may also be required. The two licences serve different regulatory functions and neither substitutes for the other.
How is custody arranged for a crypto fund?
A digital-asset fund appoints an independently licensed custodian to hold and safeguard the fund's DPT assets. In Singapore, that custodian must hold an MAS PSA licence as a Major or Standard Payment Institution. The custody arrangement is governed by a dedicated custody agreement that should address digital-asset-specific matters: key management, hard fork treatment, insolvency segregation, Travel Rule obligations, and liability for key loss. The arrangement must be disclosed in the fund's offering documents and must satisfy the due-diligence standards of the fund's target investor base.
