Banking-as-a-Service (BaaS): A Strategic Guide

A clear guide to Banking-as-a-Service (BaaS): how the model works, where the regulatory perimeter sits, sponsor-bank risk, and how to launch safely.

Banking-as-a-Service has quietly become the plumbing beneath much of modern fintech. When a non-bank brand offers an account, a card, or a payment in your app, there is almost always a licensed institution somewhere behind it, lending its permissions, its rails, and ultimately its regulatory accountability.

For founders, the appeal is obvious. Banking-as-a-Service (BaaS) lets you launch financial products in months rather than the years a licence would take, without raising the capital a bank charter demands. For incumbents and investors, BaaS is a distribution channel and a balance-sheet play. For regulators, it is increasingly a source of concern.

We work with clients on both sides of these arrangements, and the recurring lesson is the same: BaaS removes the licensing barrier, but it does not remove the regulatory substance. Understanding where responsibility actually sits is the difference between a durable business and an enforcement headline.

What Banking-as-a-Service Actually Is

At its core, BaaS is the provision of regulated banking functions, such as holding deposits, issuing payment accounts and cards, or processing transactions, through the licence of a sponsor institution, accessed by a third party via technology rather than by becoming a bank itself.

Three layers are usually present. The licensed institution, a bank or an electronic money or payment institution, holds the regulatory permissions and, where relevant, the deposit relationship. The BaaS platform or middleware provider sits in the middle, exposing the bank's capabilities through clean interfaces and handling much of the orchestration. The brand or programme manager is the customer-facing business that designs the product and owns the user relationship.

In some arrangements two of these layers are the same company. The economics, and the risk, shift considerably depending on how the stack is assembled and who is contractually accountable for what.

The Regulatory Perimeter Does Not Move

The single most important point we make to clients is this: outsourcing the technology does not outsource the obligation. When a brand sits in front of a sponsor's licence, the sponsor remains answerable to its regulator for anti-money-laundering controls, customer due diligence, safeguarding of client funds, and fair treatment of customers.

This is why a credible sponsor will look closely at the programmes it onboards. Expect scrutiny of your customer base, your geographies, your marketing claims, and your own financial-crime framework. A sponsor that asks few questions is, as at 2026, a warning sign rather than a convenience, because regulators in the UK, the EU, and the US have all signalled growing impatience with weak oversight of BaaS partnerships.

Where deposits are involved, deposit insurance and "pass-through" arrangements deserve particular care. The protection a customer believes they have often depends on precise account structuring and accurate disclosure. Misdescribing this is both a conduct risk and, in several markets, a regulatory breach in its own right.

Choosing Between Building, Renting, and Partnering

There is a spectrum of involvement, and the right point on it depends on ambition, capital, and tolerance for regulatory weight.

Renting a sponsor's licence through a BaaS provider is the fastest route to market. You move quickly and keep regulatory capital requirements off your own balance sheet, but you accept concentration risk: if your sponsor exits the programme, changes appetite, or runs into its own supervisory trouble, your product can be disrupted with limited notice. Building redundancy with a second sponsor is prudent but rarely simple.

Becoming the licensed layer yourself, typically by obtaining an electronic money or payment institution authorisation, gives you control, better unit economics at scale, and direct regulatory standing. It also brings capital requirements, governance obligations, regulatory reporting, and the cost of a compliance function that never sleeps.

A hybrid path, launching on a sponsor while pursuing your own authorisation in parallel, is common and often sensible. It lets you prove the model commercially before committing to the regulatory burden, provided you plan the migration carefully and disclose it honestly to partners.

Jurisdiction and Structure

Where you base the regulated and operating entities shapes everything downstream: which customers you can serve, how you passport or localise, and how banking partners view you.

Within the EU and EEA, an electronic money or payment institution authorisation in one member state can, subject to passporting, support activity across the bloc, which is why hubs such as Lithuania, Ireland, and Malta feature heavily in BaaS planning. In the UK, the post-Brexit regime stands separately and requires its own authorisation. In the US, the picture is more fragmented, combining federal oversight with state money-transmitter licensing, and BaaS partnerships there have drawn especially close supervisory attention.

Offshore structuring still has a role, particularly for holding companies, intellectual property, and group treasury, but we caution clients firmly against assuming that an offshore base lets the customer-facing programme escape the rules of the markets where its users live. Substance matters: regulators and banking partners increasingly expect real decision-making, real staff, and real controls in the jurisdiction whose licence you rely on. A letterbox presence invites both onboarding refusals and regulatory questions.

Common Pitfalls We See

The most frequent and most damaging mistake is treating compliance as the sponsor's problem alone. Even where the sponsor carries the formal obligation, your programme generates the transactions, the customers, and the risk. Build your own financial-crime and conduct framework from day one; it protects the relationship and your enterprise value.

A second pitfall is fragile concentration. Single-sponsor dependence has ended otherwise healthy businesses overnight when a bank withdrew from BaaS. Diversification and contractual exit protections deserve attention before, not after, launch.

Third is misleading positioning. Describing yourself as a "bank" when you are a programme on someone else's licence, or implying protections that do not apply, is a conduct risk that supervisors increasingly pursue. Precise, honest customer communication is not a constraint on growth; it is a condition of surviving long enough to grow.

Finally, founders underestimate the operational lift. Reconciliation, dispute handling, fraud monitoring, and regulatory reporting do not disappear because a platform abstracts the rails. They become your responsibility to oversee, even where you do not perform them directly.

How HPT Helps

We help founders and established groups design BaaS arrangements that are commercially fast and regulatorily durable. That includes selecting and structuring the right entities, assessing the build-versus-rent-versus-partner question against your actual ambitions, identifying suitable licensing routes and jurisdictions, and preparing the substance and governance that sponsors and supervisors expect. Where you intend to acquire your own authorisation, we coordinate the application and the transition from a sponsored launch.

If you are weighing a Banking-as-a-Service launch and want a clear-eyed view of the risks before you commit, we would be glad to talk.
