What "A" Means in Practice
A-graded banks in South Dakota are the strongest tier — institutions with composite Bank Health Scores of 80 or higher across capital, loan quality, liquidity, and profitability. Currently 33 banks chartered in South Dakota qualify. A grades typically reflect well-above-regulatory capital cushions (often 12%+ Tier 1), sub-1% nonperforming loans, and ample liquidity buffers. Many A-graded banks are conservatively run community institutions or specialty banks with focused, lower-risk loan portfolios.
For depositors: A-graded institutions face less probability of regulatory action than peers, all else equal. That said, FDIC insurance — not the bank's grade — protects deposits up to $250,000 per depositor, per insured bank, per ownership category. The grade describes regulatory cushion; insurance describes guaranteed protection.

For Depositors at A-Graded Banks
FDIC insurance — not the bank's grade — guarantees deposits up to $250,000 per depositor, per insured bank, per ownership category. Verify your bank's status and your specific coverage at FDIC.gov. The Bank Health Score and grade describe regulatory cushion in relative terms; insurance describes guaranteed protection.
For combined balances above $250,000 at a single bank, the FDIC's Electronic Deposit Insurance Estimator (EDIE) calculates exactly which dollars are insured. Account titling — joint, individual, retirement, payable-on-death — affects coverage. Federal regulators including the OCC publish the rules; FDIC.gov is the authoritative consumer source.
How These Grades Are Calculated
Every bank earns a Bank Health Score from four FDIC Call Report inputs: Tier 1 capital ratio (35%), NPL ratio inverted (30%), liquidity ratio (25%), and return on assets (10%). The 0–100 composite maps to A (80+), B (65–79), C (50–64), D (35–49), and F (under 35). Data flows from the FDIC BankFind API and the FFIEC Call Report archive. Read the full methodology.
