Episode notes
Checks Create Implicit Bank Credit
- Depositing a check creates an implicit credit extension from the bank to you because the bank pays before final settlement.
- That credit exposes the bank to two risks: the payer bouncing the check and the payee failing to reimburse the bank if recovery is attempted.
Why Banks Refuse Some Customers
- Banks decline customers who present a material risk of bounced checks because expected losses exceed the cheap embedded credit of checking accounts.
- This underwriting, not just prejudice, explains much unbanked status among higher-risk individuals.
A Typical Check-Cashing Visit
- If you're unbanked you walk into a local check-cashing shop, endorse the check, get paid from the drawer, and the clerk keeps the check.
- The business posts a clear fee schedule and the clerk often recognizes repeat customers from prior visits.
