South Dakota Credit Unions

South Dakota is home to 33 federally-insured credit unions collectively serving 351K members with $6.0B in combined assets, based on the most recent NCUA 5300 Call Report (Q4 2025). The state's average health score of 84/100 reflects the blended performance of every charter operating within its borders, state-chartered, federally-chartered, community, employer-based, and multi-SEG credit unions alike. Dakotaland of Huron currently leads the cohort with a health score of 98/100, while the full distribution spans 33 institutions ranked below.

The health distribution breaks into four bands: 24 credit unions score 80–100 (Excellent), 8 score 60–79 (Good), 1 score 40–59 (Fair), and 0 fall below 40 (Weak). These scores are a weighted composite of five NCUA-reported metrics: net worth ratio (30%), delinquency rate (25%), return on assets (15%), year-over-year member growth (15%), and loan-to-share ratio (15%). A score in the Excellent band typically indicates a net worth ratio comfortably above the 7.0% NCUA "well capitalized" floor, sub-1% delinquency, positive ROA, and a loan-to-share ratio inside the 60–80% balanced-liquidity window. Fair and Weak institutions are not necessarily in distress, NCUA supervises all federally-insured credit unions through CAMEL ratings and Prompt Corrective Action triggers, but the composite signals where financial buffers are thinner than peers.

Every credit union on this page carries NCUSIF deposit insurance up to $250,000 per depositor per ownership category, administered by the National Credit Union Administration, identical coverage to FDIC insurance at banks. Membership eligibility varies by charter: community charters serve anyone living, working, worshiping, or attending school in a defined geography, while employer-based and associational charters require a specific common bond. Rates, fees, and product offerings also vary widely across South Dakota's 33 institutions, so prospective members should verify current terms directly with each credit union before opening accounts or applying for loans.
