Liquidity & Balance Sheet
Noninterest-Bearing Deposits
Also known as Demand Deposits
Noninterest-bearing deposits — primarily demand deposit accounts (checking) — are balances on which a bank pays no interest. They are the cheapest, stickiest funding a bank can have and a key driver of net interest margin.
Formula
Schedule RC-E splits deposits into noninterest-bearing and interest-bearing. The noninterest-bearing share — largely business operating accounts — funds earning assets at zero cost, lifting margin above what the rate spread alone would produce.
Why it matters
A large noninterest-bearing base is one of banking's most valuable assets: it insulates the bank from rising rates, since this funding costs nothing regardless of the rate environment. It is the difference between a franchise that thrives when rates rise and one that gets squeezed.
How to interpret
Read noninterest-bearing deposits as a share of total deposits. A high, stable share signals strong operating relationships and pricing power; a shrinking share — as customers move idle cash into interest-bearing accounts (a 'deposit mix shift') — is an early warning of margin pressure.
Thresholds
| Range | Label | Interpretation |
|---|---|---|
| ≥ 30% of deposits | Strong | Large free-funding base; margin well insulated from rates. |
| 20-30% | Adequate | Solid noninterest-bearing share. |
| 10-20% | Watch | Limited free funding; margin more rate-sensitive. |
| < 10% | Concern | Thin free-funding base; highly exposed to rising deposit costs. |
Worked example
Frequently asked
Why are noninterest-bearing deposits so valuable?
They fund loans and securities at zero interest cost, so they directly widen net interest margin and shield the bank from rising rates. A deep noninterest-bearing base is a durable competitive advantage.
What is a deposit mix shift?
When depositors move balances out of noninterest-bearing accounts into interest-bearing savings or CDs to capture higher rates, the funding mix shifts and the bank's cost of funds rises — squeezing margin even if total deposits are unchanged.
