What is a pooled account vs. a segregated account?

A pooled account combines funds from multiple customers into a single bank account, while a segregated account maintains individual customer funds in separate bank accounts. Pooled accounts reduce banking costs by 60-80% but require complex subledger tracking systems to maintain accurate customer balances.

Why It Matters

Pooled accounts can reduce banking fees from $50-200 per account monthly to $5-20 total, saving fintech companies $500K-2M annually on banking costs. However, regulatory compliance becomes 3-5× more complex as customer protection laws require clear segregation of funds even within pooled structures. Segregated accounts offer simpler compliance but cost 10-15× more to maintain across hundreds of thousands of customers.

How It Works in Practice

  1. 1Route incoming customer deposits to either individual segregated accounts or a master pooled account based on regulatory requirements
  2. 2Maintain detailed subledger records for each customer's balance within pooled accounts down to the cent
  3. 3Reconcile pooled account bank balances against sum of all customer subledger balances daily
  4. 4Execute customer withdrawals by debiting subledger first, then transferring funds from pooled account
  5. 5Generate customer statements from subledger data while keeping actual banking activity consolidated

Common Pitfalls

Customer funds in pooled accounts may not qualify for full FDIC protection if the bank fails, requiring additional insurance coverage

Subledger system failures can create reconciliation gaps where customer balances don't match actual pooled funds

Regulatory audits become more intensive as examiners require detailed proof of customer fund segregation within pooled structures

Cash flow timing mismatches occur when customer withdrawals exceed immediately available pooled account balances
