Liquidity & Balance Sheet
Deposit Growth Rate
Also known as Deposit Growth
The deposit growth rate is the year-over-year percentage change in a bank's total deposits — a direct read on whether its funding base is growing, stable, or running off.
Formula
Current-quarter total deposits minus total deposits four quarters earlier, divided by the prior-year figure.
Why it matters
Deposits are a bank's cheapest, stickiest funding. Shrinking deposits force a bank toward costlier wholesale funding or asset sales, pressuring margins and liquidity. Deposit flight was the proximate trigger of the 2023 regional-bank failures.
How to interpret
Modest positive growth is healthy. A sharp decline — especially in a single quarter — can signal a confidence problem or aggressive runoff of high-cost deposits. Read alongside the uninsured-deposit ratio (which scales the run-risk) and the cost of funds (which shows what the bank is paying to keep deposits).
Thresholds
| Range | Label | Interpretation |
|---|---|---|
| > 5% | Growing | Healthy, expanding core funding base. |
| 0–5% | Stable | Flat funding; typical in competitive markets. |
| −5–0% | Runoff | Modest deposit loss; watch funding mix and cost. |
| < −5% | Flight | Material deposit loss — liquidity and confidence risk. |
Worked example
Frequently asked
Why does deposit growth matter more than asset growth for safety?
Deposits are the funding side of the balance sheet. A bank can usually find assets to buy, but losing low-cost, stable deposits forces it into expensive, flighty wholesale funding — exactly the squeeze that turned unrealized securities losses into failures in 2023.
Is shrinking deposits always bad?
Not always. Some banks deliberately let high-cost, rate-chasing deposits run off to protect their margin. The concern is involuntary flight of core relationship deposits, which is best read together with the uninsured-deposit ratio and cost of funds.
