A **partner bank** (also called a **sponsor bank**) is a licensed bank that holds customer deposits, issues cards or provides compliance infrastructure for a non-bank brand that owns the app and customer relationship.[^pb1] This [partner-bank](/wiki/partner-bank) model—often delivered via [banking as a service](/wiki/banking-as-a-service)—defines many U.S. [neobanks](/wiki/neobank) such as [Chime](/wiki/chime), [Cash App](/wiki/cash-app) and [Mercury](/wiki/mercury).

## Overview

The fintech markets and supports the product; the partner bank is the regulated deposit-taker (for example FDIC-insured in the U.S.). Contracts allocate compliance duties, but regulators increasingly hold both sides accountable when programmes fail.

## Trade-offs

Advantages include faster launch and lower capital requirements than a full charter. Risks include partner concentration, programme shutdowns, and customer confusion about who "is the bank." The Synapse bankruptcy highlighted operational and custodial risks in U.S. BaaS chains.
