The Growing Compliance Burden for Sponsor Banks in Banking-as-a-Service Models

Growing regulatory scrutiny of Banking-as-a-Service partnerships has increased compliance pressure on sponsor banks, particularly smaller institutions that rely on fintech relationships to expand deposits, customer reach, and technology capabilities. Following regional-bank failures in 2023, regulators have intensified enforcement related to capital, fraud, fair lending, anti-money-laundering, and KYC requirements, expecting banks to maintain demonstrable, real-time control over fintech customer onboarding, identity verification, transaction monitoring, risk ratings, and other operations conducted under the bank’s charter. Sponsor banks, though representing a small share of U.S. banks, have faced a disproportionate number of severe actions, with consent or cease-and-desist orders bringing fines, costly remediation, operational restrictions, reputational harm, and limits on growth or new partnerships. The discussion argues that periodic audits and sampled reviews are no longer sufficient, and that banks need centralized data, consistent compliance controls, ongoing risk assessments, entity resolution, sanctions screening, and transparent governance across their fintech portfolios. It anticipates continued enforcement and possible regulatory updates, while promoting integrated oversight technology, including Socure’s Control Center, as one approach for consolidating compliance monitoring and audit evidence.
