Why payment processors get declined for bank accounts
The primary reason your PSP is being declined is risk classification. From a bank’s perspective, any business that processes payments for third-party merchants inherits the risk of those merchants. This includes exposure to high chargeback rates, potential for money laundering, and the complexity of monitoring transactional flows across various industries. Mainstream banks and fintechs like Mercury or Airwallex are built for lower-risk, direct-to-consumer or B2B business models. Their automated onboarding and monitoring systems are not designed to underwrite a payment processor's nuanced risk profile.
When a bank's compliance team sees an application for a PSP bank account, they do not just see your company. They see a network of underlying merchants, each with its own risk level. They see the potential for regulatory fines if your AML/CFT controls are deemed insufficient. Rather than invest the significant compliance resources required to properly understand and monitor your business, it is commercially and operationally simpler for them to issue a denial. It is not a judgement on your business's quality, but a reflection of their own rigid, volume-based business model which cannot accommodate your complexity.
