Banking in Idaho — What the FDIC Data Shows
Idaho is home to 10 FDIC-insured banks holding a combined $12.0B in total assets and $10.2B in customer deposits. The average PlainBankData health score across all Idaho banks is 56/100, derived from four FDIC Call Report metrics: Tier 1 Capital Ratio, Return on Assets, Texas Ratio, and Efficiency Ratio. The largest institution headquartered in the state is D. L. Evans Bank of Burley, with $3.7B in assets and a health grade of F.
Looking at the grade distribution, 4 banks (40%) earn an A or B grade — signaling strong capital ratios and healthy profitability — while 3 sit at Grade C (meeting regulatory minimums with some areas to monitor) and 3 (30%) carry a D or F grade, indicating notable financial weaknesses in one or more of the four scoring pillars. Since 2000, Idaho has seen 2 bank failures tracked on the FDIC Failed Bank List. Most of those failures clustered during the 2008–2010 financial crisis, with resolution typically handled through acquisition by a stronger institution.
Not financial advice. These figures are drawn from public FDIC Call Reports and the FDIC Failed Bank List. Health grades are PlainBankData's interpretation of regulatory filings, not official FDIC ratings or endorsements. A lower grade does not mean your money is at risk — every dollar on deposit at any FDIC-insured bank is protected up to $250,000 per depositor, per ownership category, regardless of the institution's financial condition.

How to Read the Idaho Bank Directory
This page lists every FDIC-insured bank with a primary regulatory address in Idaho. Inclusion does not depend on charter type — both state-chartered and nationally-chartered banks appear here when the FDIC institution directory places their headquarters in this state. Branch locations, ATM networks, and credit unions are NOT in scope; this is a headquarters-anchored view. The 10 institutions shown reflect the most recent quarterly FDIC release; counts will change at each refresh as institutions merge, are acquired, or close.
Health Grade Interpretation
Each bank's letter grade (A through F) is computed from four FDIC-reported metrics: Tier 1 capital ratio, return on assets, the Texas Ratio (non-performing assets ÷ tangible capital), and the efficiency ratio. Grades are relative — every quarter we recompute thresholds against the full FDIC universe, so a "B" today may have been an "A" last cycle if the median improved. Across Idaho, 4 institutions (40%) currently sit in the A or B band, while 3 (30%) fall in the D or F band. The C cluster — the broad middle — typically captures roughly half of any state's banks and is not a warning signal on its own.
What State Concentration Tells You
Banks register their headquarters in Idaho for several distinct reasons: regional community service (the bulk of small community banks), favorable trust law (a handful of states attract large national fiduciary operations), regulatory familiarity, or historic charter inheritance. A high concentration of total assets in a single state — South Dakota, Delaware, and Ohio are well-known examples — usually reflects a few very large institutions choosing the state for tax or regulatory reasons, not breadth of local banking competition. Below the top of the table, the long tail of mid-sized and community banks gives a clearer picture of local market structure.
When Failures Matter
Since 2000, 2 banks headquartered in Idaho have failed. Every depositor at those banks was made whole up to the standard FDIC insurance ceiling (currently $250,000 per depositor, per ownership category, per institution). Bank failures cluster around macro events (the 2008-2010 wave, the regional bank stress of 2023) rather than steady attrition, so a clean recent record at the state level does not imply state-level safety — it usually reflects the absence of a triggering shock. The "Under Stress" ranking is more useful for forward-looking comfort than the historical failure count, because it scores current capital and credit-loss capacity.
Sources, Refresh Cadence, and Corrections
Every figure on this page derives from the FDIC Quarterly Banking Profile and the FDIC Institution Directory, both of which are public-domain government datasets. We re-pull the data on the FDIC's schedule (a quarterly release plus monthly institution-directory delta files for merger and closure events). Asset and capital figures are reported as of the most recent quarter-end and lag the calendar by approximately ninety days — this is the FDIC's reporting lag, not ours. If a specific bank record looks wrong (renaming, merger, missing fields), the contact page accepts corrections; we reconcile them against the source feed at the next refresh.
