The payments industry promises instant settlement and border-free commerce, yet behind every “Pay Now” button lies a dense lattice of laws. Payment-system regulations and licensing frameworks decide who may hold client funds, process cards, issue e-money, or run a digital wallet. Ignore them and your launch can stall for months—or worse, trigger enforcement action and frozen balances. Below is the strategic briefing founders, CFOs and product teams need before writing a single line of code.
Map your regulatory footprint first
Where customers live and where you will physically touch their money drive everything that follows. A Dutch fintech serving only EEA merchants faces PSD2 today and PSD3 tomorrow. Add US clients and the same company suddenly needs state-by-state money-transmitter licences plus FinCEN registration. Layer on APAC and MAS approval under Singapore’s Payment Services Act enters the picture. Sketch the corridors now; licence gaps are cheaper to close during planning than under deadline pressure.
Understand the licence spectrum
- Payment Institution (PI) or Electronic Money Institution (EMI)—core EU passports issued by local regulators such as the Dutch DNB or the UK’s FCA. An EMI may hold client funds in safeguarded accounts and issue stored-value; a PI cannot.
- Money-Transmitter Licence (MTL) in the United States—fifty-state patchwork plus federal MSB registration with FinCEN. Some states offer exemptions or “bank sponsorship,” but most startups still collect fifteen-plus approvals before nationwide launch.
- Payment Services Act (PSA) licences in Singapore—cover account issuance, domestic and cross-border transfers, merchant acquisition, and digital-token dealings. Recent amendments expand user-protection and custody rules.
- Specialised charters—Australia’s Authorised Deposit-taking Institution (ADI) path for wallets holding AUD, Canada’s Retail Payment Activities Act for non-bank PSPs, and Brazil’s IP licence for PIX participants.
Each tier adds cost, capital requirements and audit obligations; choose the minimum set that still lets you scale for three years.
Capital, safeguarding and reporting duties
EMIs in the UK must hold initial capital of £350 000 and segregate customer funds either in a ring-fenced bank account or via insurance. PIs start at £20 000, stepping up with monthly volume. In the US, surety-bond or net-worth requirements range from US$10 000 in Tennessee to US$2 million in New York. Singapore’s Major Payment Institution tier demands a S$250 000 security deposit and daily safeguarding within a trust or MAS-approved custodian. Plan treasury operations early; regulators want proof of safeguarding before they issue even a provisional licence.
Compliance playbook that accelerates approval
• Draft a governance framework showing board oversight, three-lines-of-defence risk management and an audit calendar.
• Deploy a transaction-monitoring system built for ISO 20022 data; regulators increasingly question legacy MT and CSV pipes.
• Document outsourcing. Cloud providers hosting settlement engines count as “material outsourced service providers” and need contractual controls.
• Align with the latest Strong Customer Authentication rules; PSD3 raises bar on biometrics and passkey flows.
Good documentation can shave months off supervisory Q&A and demonstrates a compliance culture investors respect.
Managing multiple regimes without drowning
A modern payment stack routes every transaction through a rules engine: if sender and receiver sit inside the EEA, process under PSD2; if the payer is in Texas, trigger US KYC, escrow state funds and send batch reports to the Texas Department of Banking. SaaS platforms and reg-tech APIs automate much of this logic, but a single head of compliance must own the map. Fragmented responsibility is the number-one reason regulators pause licence reviews.
Change is constant—track it
• PSD3 and the parallel Payment Services Regulation are due to apply from late 2026, merging e-money and payment rules and forcing more fee transparency.
• The UK Financial Services and Markets Act 2023 is rolling out secondary legislation that replaces EU-retained law; expect a new UK-specific payments perimeter by 2026.
• MAS phased amendments from April 2024 to October 2024, expanding regulation to cover digital-token custody and cross-border money transmission.
• US state regulators continue to harmonise exams via the Multistate MSB Licensing Agreement, reducing audit fatigue if you opt in.

Launch checklist before you go live
- Confirm board-level approval of the capital plan and safeguarding policy.
- Test ISR (incident, system and reporting) playbooks with simulated outages.
- Obtain all local banking partners’ acknowledgement of your licence status.
- File initial regulatory returns: MSB Form 107, FCA Connect data pack, MAS Form 1, whichever applies.
- Switch on a horizon-scanning feed so product changes never outpace legal ability to serve the new flow.
In payments, scale without compliance is temporary; compliance without scale is expensive. Align the two from day one and you gain not just a licence but a durable competitive moat.
