# Sponsor-Bank Fees

Sponsor-bank fees are what a fintech pays the licensed bank whose charter it operates on: charges per account, per transaction and per card, a share of the interchange the fintech's cards earn, a programme or platform fee, and the cost of the compliance the bank performs on the fintech's customers. They are the price of not having a licence, and for many neobanks and card programmes the largest cost of revenue.

**Also known as:** Partner bank fees, BaaS fees, Program bank fees

## Key facts

- **Used at:** banking-as-a-service arrangements — neobanks, card programmes, embedded-finance products, lending fintechs that originate through a bank
- **Binding:** yes — a programme agreement with fees, minimums, compliance obligations, reserves and a termination clause that the bank can exercise, sometimes at its regulator's request
- **Typical structure:** a monthly minimum or platform fee; $0.25–1.00 per active account per month; per-transaction fees in cents; 15–30% of interchange retained by the bank; pass-through of card scheme and processor costs; fees for KYC, disputes and ACH returns
- **Typical trend:** rising since 2023 as US bank regulators issued consent orders against sponsor banks and the collapse of the middleware provider Synapse in 2024 left fintech customers unable to reach their money
- **Parties:** the sponsor bank, the fintech, often a middleware provider between them, the card processor, and the bank's regulator, whose view of the arrangement decides its future

## How sponsor-bank fees work in practice

A neobank without a charter cannot hold deposits or issue cards. It contracts with a bank that can: the accounts are the bank's, the cards are issued by the bank on the network's rules, and the fintech is the bank's programme manager, running the app, the marketing and the customer service. The bank charges for what it provides — the licence, the deposit insurance, the scheme membership, the compliance oversight it is responsible for — and keeps a share of the interchange the cards generate, which is the fintech's main revenue.

The economics turn on the interchange share and the minimums. A card programme earning 1.5% of spend in interchange and giving the sponsor 25% of it keeps 1.125%; from that it pays the processor, the card manufacturer, the fraud losses and the sponsor's per-account fees. At low volume the monthly minimum dominates; at scale the interchange share does, which is why growing fintechs renegotiate or seek a second sponsor, and why the largest eventually buy a bank.

The risk in the arrangement is that it is the bank's, not the fintech's. Regulators supervise the bank for the programme's compliance; a consent order on the sponsor can freeze onboarding for every programme it runs, and the bank's remedy is to raise fees, impose reserves or give notice. A buyer of a sponsored fintech reads the programme agreement before the financials.

## Example

A neobank has 500,000 active accounts and $1.2bn of annual card spend. Its sponsor charges $0.50 per active account per month — $3m a year — plus 25% of the $18m of interchange the spend earns, $4.5m, plus $1.1m of KYC, dispute and return fees: $8.6m a year, against $18m of gross interchange. After the processor and fraud losses the neobank nets about $5m. The sponsor, under a regulator's consent order, raises the interchange share to 30% and requires a $4m reserve: the net falls to $3.5m and the balance sheet loses $4m of cash. A second sponsor takes fourteen months to onboard and asks for 22%. The neobank's board, which had planned a charter application "in a few years", starts it.

## Common mistakes

- Modelling revenue on gross interchange and treating the sponsor's share as a cost to negotiate later.
- One sponsor, no second, and a termination clause with 90 days' notice.
- Not reading the sponsor's consent order, if it has one, before signing.
- Assuming the sponsor's compliance is the fintech's compliance; the regulator holds the bank responsible and the bank holds the fintech.
- In an acquisition, valuing the deposits as the fintech's when they are the bank's, and moveable only with its agreement.
