Operating Layer, Reserve Layer, Term Layer
The most common structure at Exchange Bank for a mature small-business depositor is three-layered. Layer one is the operating checking account — just enough balance to cover payroll, trade payables and a working buffer. Layer two is a Business Money Market account holding 60-90 days of operating expense, earning tiered APY. Layer three is a Business CD ladder holding long-horizon reserves locked at the higher end of the yield curve. A Business Sweep Account automates the checking-to-money-market move nightly, and CDs are refreshed on maturity.
Per the FDIC's Quarterly Banking Profile, community banks consistently report a majority of small-business deposits in checking and money-market categories, reflecting the operating-then-reserve priority order.
