Many banking apps are not banks. They provide the interface and the customer relationship while a licensed institution holds the deposits behind them.
A banking licence is expensive to obtain and hold
Deposit-taking requires authorisation, minimum capital, liquidity requirements, governance structures and continuous supervision, all of which take years and substantial resources to establish.
A firm wanting to launch a product quickly can instead partner with an existing licence holder, which supplies the regulated functions.
The arrangement lets the front-end firm concentrate on product design and customer acquisition, which is where it expects to compete.
The division of responsibilities is uneven
The partner bank holds the deposits, maintains the accounts of record and carries the regulatory obligations attached to them.
The app provider handles onboarding, the user experience, support and often the day-to-day monitoring, under an agreement setting out how each obligation is met.
Because the regulated duty sits with the bank, its risk appetite constrains what the app can offer, which is why features sometimes appear or disappear without explanation.
Economics are split at the source
Revenue from deposits, interchange and lending is divided between the partners according to their agreement, so the app receives only part of what the relationship generates.
This narrows margins relative to a fully licensed institution and pushes these firms towards subscription tiers, foreign exchange revenue and other services.
It also explains why successful providers frequently pursue their own licence once scale justifies the cost, since the economics improve substantially.
Protection depends on where the money sits
Where funds are held as deposits at a licensed bank, they normally fall within the relevant insurance scheme, subject to that scheme's limits and rules.
Where a provider is an electronic money institution instead, customer funds are typically safeguarded in segregated accounts rather than insured, which is a different protection with different consequences on failure.
The distinction is rarely prominent in marketing, and the arrangements vary by jurisdiction, so the terms of the specific account are what determine the position.
Reconciliation is the recurring weak point
Records held by the app and by the partner bank must agree, and pooled account structures make that reconciliation more complex than it appears.
Failures in this process have left customers unable to access balances even where the underlying money existed, because ownership could not be evidenced quickly.
Supervisory attention has increasingly focused on these arrangements for that reason, and requirements on both partners have tightened accordingly.
