Open Banking APIs for Offshore Fintech: A Guide

How offshore fintechs can use open banking APIs for payments and data, the licensing and access realities, and the pitfalls to avoid.

Open banking changed the economics of building financial products. Instead of negotiating bilateral integrations with each bank, a fintech can use standardised open banking APIs to initiate payments and access account data with the customer's consent. For an offshore or internationally structured fintech, this is both an opportunity and a source of confusion.

The opportunity is obvious: lower integration cost, faster product launch, and the ability to offer account-to-account payments and data-driven services without holding the underlying accounts. The confusion comes from a mismatch many founders discover late. Open banking is built on regulated access, and that regulation is tied to where you operate, not where you incorporate.

This guide sets out how open banking actually works for a cross-border fintech, what licensing the API access usually requires, and where offshore structures help and where they do not.

What open banking actually gives you

Open banking, in its mature form, exposes two broad capabilities through APIs. Payment initiation lets an authorised provider trigger a payment directly from a customer's bank account, with the customer's consent, without card rails. Account information lets an authorised provider read a customer's transaction and balance data to power budgeting, lending decisions, accounting and verification.

In Europe and the United Kingdom these are regulated activities under the payment-services regime: payment initiation services (PIS) and account information services (AIS). The bank is obliged to provide compliant API access, but only to providers that hold the relevant authorisation or are operating under an agent or partner arrangement with one.

Elsewhere, open banking ranges from formal regulatory mandates to purely commercial, bank-led API programmes. The capabilities look similar, but the access conditions differ sharply by market, which is the first thing a cross-border fintech must map.

The licensing reality for offshore fintechs

Here is the point founders most often miss. An offshore holding company does not grant access to European or UK open banking. The right to connect to those APIs flows from holding the appropriate regulated permission in the relevant jurisdiction, or from partnering with a licensed provider.

In practice there are three common routes. The first is to obtain your own authorisation as a payment institution or e-money institution with the PIS and AIS permissions you need. This gives the most control and the strongest commercial position, but it carries capital, governance and substance obligations in the licensing jurisdiction.

The second is to work through a regulated aggregator or technical service provider that already holds the permissions and exposes a single, unified API across many banks and countries. This is the fastest route to market and removes much of the licensing burden, at the cost of margin and some dependency.

The third is the agent or distributor model, where you operate under the licence of a principal firm. This sits between the other two and suits fintechs that want more brand control than pure aggregation but are not ready for full authorisation.

An offshore company can sit above any of these as the group parent, the IP owner, or the contracting entity for non-regulated services. What it cannot do is substitute for the regulated touchpoint that the APIs require.

Structuring across borders

A sensible cross-border design usually separates functions. The regulated operating entity is established where the licence lives and where genuine substance can be demonstrated, because regulators expect mind and management to match the permission. The group holding company may sit in a jurisdiction chosen for treaty access, investor familiarity or asset protection. Technology and IP can be held in a separate vehicle and licensed to the operating company on arm's-length terms.

This separation must be more than paper. Regulators and banks increasingly look through structures to where decisions are made, where staff sit, and where risk is genuinely managed. Substance requirements, transfer pricing on intra-group charges, and beneficial ownership transparency all bear on how the pieces fit together, and they should be designed in from the start rather than retrofitted.

Data protection and consumer trust

Open banking runs on customer consent and customer data, so data protection law is not a side issue. Where you serve customers in Europe or the United Kingdom, the data protection regime applies based on where those customers are, regardless of your incorporation. That means lawful bases for processing, clear consent flows, data-minimisation, and proper handling of cross-border transfers to any offshore entity in the group.

Security expectations are correspondingly high. Strong customer authentication, secure API credentials, and robust handling of the access tokens that authorise data sharing are baseline. A breach in this space is both a regulatory event and a reputational one, and trust is the currency open banking products ultimately sell.

Common pitfalls

The most frequent mistake is assuming incorporation equals access. Founders register an offshore company, build a product, and then discover they cannot legally connect to the APIs in their target market without a licence or a licensed partner.

A second pitfall is underestimating market fragmentation. Open banking coverage, data quality and reliability vary widely by country and even by bank. A product that works smoothly in one market may face patchy access in another, which is why many fintechs lean on aggregators for breadth.

A third is thin substance in the licensing jurisdiction. A permission granted on the basis of local management cannot credibly be run entirely from elsewhere; supervisors increasingly test this, and banking partners do too.

A fourth, more subtle pitfall is treating consent as a one-time formality. Open banking access rests on customer consent that is specific, informed and revocable, and that typically expires and must be refreshed. Products built without proper consent lifecycle management — re-authentication flows, clear scopes, and easy withdrawal — risk both regulatory criticism and broken user experiences when access silently lapses. We see this overlooked far more often than the headline licensing questions.

Who this route suits

Open banking suits fintechs building payments, lending, accounting, verification and personal-finance products that benefit from direct, low-cost access to bank accounts and data. It rewards businesses willing to be honest about where their customers are and to put the regulated entity where the law requires.

It suits less well founders hoping that an offshore wrapper alone will unlock regulated European access. That gap is the source of most disappointment we see.

How HPT helps

We help fintech founders design cross-border structures that respect where regulation actually bites, decide between own-licence, aggregator and agent routes, establish substance in the right jurisdiction, and coordinate the legal, tax and data-protection workstreams that open banking products require.

If you are planning an open banking product across borders, we would welcome the conversation.
