How Regulations Apply Differently to Fintechs vs Traditional Banks

Not All Financial Institutions Are Created Equal

A common misconception among fintech founders is that regulatory requirements are identical for all financial institutions. In reality, AML/KYC obligations vary significantly depending on your charter type, licensing status, and the nature of your services. Understanding these differences is critical for right-sizing your compliance program — investing too little creates regulatory risk, while investing too much burns capital unnecessarily.

Licensing and Charter Types

The first variable is what kind of entity you are:

• Chartered banks are directly supervised by their primary federal regulator (OCC, FDIC, or the Federal Reserve) and must maintain a comprehensive BSA/AML program per 12 CFR 21.21 (OCC) or equivalent.
• Money transmitters / MSBs register with FinCEN at the federal level and obtain state-by-state money transmitter licenses (MTLs). Each state has its own examination cadence, capital requirements, and AML expectations. As of 2024, 49 states plus DC, Puerto Rico, and the USVI require MTLs (Montana is the exception).
• EMIs (Electronic Money Institutions) in the EU/UK operate under specific licensing regimes (e.g., the Electronic Money Regulations 2011 in the UK) with AML requirements that mirror but don't identical match those of credit institutions.
• Payment Institutions under PSD2 in the EU have AML obligations but may face lighter prudential requirements than banks.

The Proportionality Principle

Most modern AML frameworks incorporate the concept of proportionality — the idea that compliance obligations should be scaled to the nature, size, and complexity of the institution. In practice, this means:

• A small payment fintech processing $10M annually shouldn't be expected to have the same compliance infrastructure as JPMorgan Chase.
• However, proportionality is not a get-out-of-jail-free card. Regulators still expect the fundamentals: risk assessment, policies and procedures, a qualified compliance officer, training, and independent testing.
• The FCA's approach is instructive: they state that "the nature and extent of the measures a firm takes should be proportionate to the risks it faces," but they also emphasize that "all firms must be able to demonstrate that the extent of their measures are appropriate in view of the risks of money laundering and terrorist financing."

Practical example: A bank might have a 50-person AML compliance team with three lines of defense, a dedicated financial intelligence unit, and a $5M annual technology budget. A Series A fintech with similar products might achieve comparable compliance outcomes with 3-5 compliance professionals, a well-configured SaaS transaction monitoring tool, and clear escalation procedures — provided the risk assessment justifies this approach and it is well-documented.

Banking-as-a-Service (BaaS) Implications

Many fintechs don't hold bank charters themselves — they partner with sponsor banks through Banking-as-a-Service arrangements. This creates a layered compliance model with shared responsibilities that regulators are increasingly scrutinizing:

• The OCC's 2023 guidance on third-party relationships (OCC Bulletin 2023-17) made clear that banks cannot outsource their BSA/AML compliance obligations. Even when a fintech partner performs KYC or transaction monitoring, the bank remains ultimately responsible.
• The FDIC's enforcement actions against partner banks (such as the consent orders issued to Cross River Bank and Blue Ridge Bank in 2022-2023) demonstrate that regulators are holding banks accountable for their fintech partners' compliance failures.
• Fintechs in BaaS arrangements must understand:
  • Your sponsor bank will dictate minimum AML/KYC requirements — and these will typically exceed what your license alone requires
  • The bank has the right (and obligation) to audit your compliance program
  • If the bank receives an enforcement action related to your program, they may terminate the partnership on short notice
  • You must share SAR and CTR data with the bank, which files the reports with FinCEN

Key Differences in Practice

Actionable Checklist

• ☐ Map your exact regulatory status: charter type, licenses held, jurisdictions covered
• ☐ If using a BaaS model, obtain and review your sponsor bank's BSA/AML compliance manual — your program must align with it
• ☐ Document your proportionality rationale: why your program is sized appropriately for your risk profile
• ☐ Review your partnership agreements for compliance-related termination clauses and audit rights
• ☐ Build a "regulatory escalation" plan: what happens if your sponsor bank receives an enforcement action
• ☐ Track the regulatory trend toward direct fintech supervision (e.g., the CFPB's larger participant rulemaking for digital wallets) and plan accordingly
