MAS requires progressive capital build-up to SGD1.5B for full-functioning digital banks, while wholesale banks face fixed SGD100M requirement.

Singapore's digital bank framework, established by the Monetary Authority of Singapore (MAS) in 2019, imposes distinct minimum paid-up capital thresholds for full and wholesale licences, with the full bank capital requirement following a phased progression from SGD15 million to SGD1.5 billion, reflecting MAS's calibrated approach to balancing innovation with financial stability.

Digital Bank License Framework: Two-Tier Structure

MAS opened applications for up to five digital bank licences in August 2019, creating two distinct licence types: the Digital Full Bank (DFB) and the Digital Wholesale Bank (DWB). The framework was designed to introduce new competition into Singapore's banking sector while maintaining prudential safeguards.

All digital banks must be incorporated in Singapore, with their headquarters located in the country and controlled by Singaporeans. This requirement ensures that digital banking operations remain under domestic regulatory oversight and aligned with national financial stability objectives.

The two-tier structure reflects MAS's assessment that different business models carry different risk profiles. DFBs are intended to serve retail customers and compete directly with incumbent retail banks, while DWBs focus on small and medium-sized enterprise (SME) and corporate clients, operating under a narrower mandate.

Capital Requirements and Progression Pathway

The minimum paid-up capital requirements vary significantly between the two licence types and, for DFBs, evolve through a staged progression.

A DFB commences operations as a "Restricted DFB" with an initial minimum paid-up capital of SGD15 million, as confirmed by MAS's eligibility criteria and multiple law firm analyses (Sources 2, 4, 6). This low entry threshold is designed to allow new entrants to establish their technology platforms and risk management systems before scaling.

The restricted DFB must then progressively increase its paid-up capital to SGD1.5 billion to graduate to a full-functioning digital bank (Sources 2, 4, 6). MAS does not prescribe a rigid timeline for this progression but expects each applicant to present a viable plan for reaching the SGD1.5 billion threshold within a reasonable period (Source 4, 7).

For DWBs, the capital requirement is fixed: a minimum paid-up capital of SGD100 million, with no phase-in process (Sources 2, 3, 5). This higher entry barrier relative to the restricted DFB reflects the wholesale bank's ability to accept larger deposits without the same retail depositor protections.

Applicants for both licence types must demonstrate firm and ready sources of funds at the point of application, with DFB applicants specifically required to show a reasonable plan to build up the SGD1.5 billion in capital needed to become fully functioning (Source 7).

Operational Restrictions for Restricted DFBs and DWBs

The capital requirements are paired with operational restrictions that limit risk exposure during the early stages.

Restricted DFBs face an aggregate deposit cap of SGD50 million and an individual depositor cap of SGD75,000 (Sources 2, 4, 6). During the entry phase, these banks may only solicit deposits from shareholders, employees, and related parties—they cannot widely solicit deposits from the general public (Sources 2, 4). Business restrictions limit restricted DFBs to offering only simple credit and investment products; they are not permitted to offer complex investment products such as structured notes or engage in derivatives activities beyond risk management (Sources 2, 6).

DWBs face a different set of restrictions tailored to their wholesale focus. They cannot accept individual deposits except for fixed deposits of at least SGD250,000 (Sources 2, 5). However, they may take wholesale deposits from SMEs and corporate clients (Source 2). This structure allows DWBs to serve business customers without exposing retail depositors to the risks of a less-established institution.

Pathway to Full Functioning Digital Bank

The progression from restricted DFB to full DFB is governed by clear criteria and expected timelines. MAS expects a restricted DFB to remain in the entry phase for one to two years, with full functioning achieved within three to five years from commencement of business (Source 4).

MAS will relax deposit caps and business restrictions progressively once a restricted DFB demonstrates good risk management capabilities (Sources 2, 4). The aggregate deposit cap may be increased from SGD50 million as the bank demonstrates operational maturity, with wholesale deposits excluded from the cap once the bank's paid-up capital reaches SGD100 million (Source 6).

To graduate to full DFB status, the bank must meet the SGD1.5 billion minimum paid-up capital requirement and demonstrate a satisfactory compliance track record, quality loan portfolio, strong risk management, and overall profitability (Sources 2, 6). Once approved as a full DFB, the bank faces no deposit caps, may accept all depositors, and must comply with the same capital adequacy and liquidity requirements as domestic systemically important banks—including a 6.5% Common Equity Tier 1 Capital Adequacy Ratio, 10% Total CAR, and full 100% liquidity coverage and net stable funding ratios (Sources 2, 6).

The calibrated capital requirements are likely to attract established fintech consortia and large corporates with the financial capacity to commit to the SGD1.5 billion trajectory, while discouraging smaller entrants lacking deep capital backing. This dynamic will shape Singapore's competitive digital banking landscape as the first batch of licensees—including Grab-Singtel consortium, Sea Limited, and others awarded licences in 2020—approach full operation and the graduation milestones that will determine whether MAS's experiment in staged digital bank licensing achieves its intended balance of innovation, competition, and stability.
