Dollar amounts are total figures from the FDIC call report. The Texas Ratio is computed by BankGrade from FDIC fields (see methodology); all other figures are reported directly by the FDIC. ROA is annualized by the FDIC from year-to-date net income. Estimate-free — but verify on the FDIC source before relying on it.
What each metric means
- Capital ratio (12.4%): equity capital as a share of total assets — the simplest cushion measure. Higher is sturdier; most large banks sit between 8% and 12%. First Interstate Bank ranks #38 of 118 on this measure.
- Risk-based capital ratio (15.1%): capital measured against risk-weighted assets, the regulatory yardstick. Banks are generally considered "well capitalized" at roughly 10% or above under Prompt Corrective Action rules.
- Nonperforming-asset ratio (0.62%): problem assets (loans past due 90+ days or in nonaccrual, plus repossessed property) as a share of total assets. Lower is better.
- Return on assets (1.02%): annualized net income divided by assets — how profitably the bank uses its balance sheet. Around 1% or higher is healthy for a large US bank.
- Texas Ratio (4.69%): nonperforming assets divided by the sum of equity and loan-loss reserves. A stress gauge — see the explainer.

Is your money safe at First Interstate Bank?
The single most important fact about deposit safety is FDIC insurance, not any ratio on this page. The FDIC insures deposits up to $250,000 per depositor, per insured bank, per ownership category. If you keep more than that at one bank, the coverage calculator shows how to structure accounts so all of it is insured. The health metrics here describe the bank's balance sheet on one quarterly snapshot — they are useful context, but they are not a prediction and not advice.
