Idaho's 26 credit unions entered 2026-Q1 with asset growth accelerating to 4.74% — 2.10 pp above the national 2.64% — and loan growth of 3.63%, vastly outpacing the national 0.31%. Yet profitability softened, with ROA declining to 0.74% from 0.83% in 2025-Q4 and 0.79% a year ago, now just 6 bps above national. Member growth, while still positive at 1.08%, decelerated sharply from 6.77% in 2025-Q1. Delinquency rose 0.17 pp year-over-year to 0.87%, above the national 0.78%. The central tension: robust balance-sheet expansion is occurring alongside tightening margins and rising credit stress.

— YoYMember Engagement
Member Growth (YoY %)
Member growth decelerated on both timeframes in 2026-Q1, slipping to 1.08% from 1.25% in 2025-Q4 (a 0.17 pp QoQ deceleration) and sharply from 6.77% in 2025-Q1 (a 5.69 pp YoY deceleration). Despite the slowdown, Idaho CUs remain meaningfully ahead of the national average of -0.65%, outperforming by 1.73 pp. The pace of membership expansion is clearly normalizing after an exceptional 2025, and sustaining positive growth in a national environment where membership is contracting represents a continued competitive advantage.
Profitability
Return on Assets (%)
Net Interest Margin (%)
Profitability declined on both timeframes. ROA fell to 0.74% in 2026-Q1 from 0.83% in 2025-Q4 (a 9 bp QoQ decrease) and from 0.79% in 2025-Q1 (a 5 bp YoY decrease). NIM held essentially stable quarter-over-quarter at 3.65% versus 3.66% in 2025-Q4, though it improved 6 bps year-over-year from 3.59% in 2025-Q1. The cohort remains 6 bps above the national ROA of 0.67%, but the NIM of 3.65% trails the national 3.70% by 5 bps. Margin compression and rising credit costs are squeezing the bottom line despite modest NIM improvement year-over-year.
Growth
Asset Growth (YoY %)
Member Growth (YoY %)
Idaho CUs posted strong growth momentum in 2026-Q1. Asset growth accelerated to 4.74% from 4.45% in 2025-Q4 (+0.29 pp QoQ), though it decelerated significantly from 8.18% in 2025-Q1 (-3.44 pp YoY). Loan growth accelerated to 3.63% from 3.41% in 2025-Q4 (+0.21 pp QoQ); year-over-year comparison data is unavailable. Both metrics substantially exceed national benchmarks — asset growth by 2.10 pp and loan growth by 3.31 pp — signaling that Idaho institutions are capturing market share even as the pace of expansion moderates from last year's elevated levels.
Risk & Credit Quality
Delinquency Rate (%)
Net Worth Ratio (%)
The risk profile shows a mixed but cautionary picture. Delinquency was essentially stable quarter-over-quarter at 0.87% versus 0.89% in 2025-Q4 (a 2 bp improvement), but rose 0.17 pp year-over-year from 0.70% in 2025-Q1, now sitting 10 bps above the national 0.78%. Charge-offs improved on both timeframes, decreasing to 0.46% from 0.54% in 2025-Q4 (-8 bps QoQ) and from 0.59% in 2025-Q1 (-0.13 pp YoY), though still 11 bps above the national 0.35%. Net worth strengthened to 11.55% from 11.47% in 2025-Q4 and 11.20% a year ago, though it trails the national 13.61% by 2.07 pp.
Portfolio Mix
First Mortgage (%)
Indirect Auto (%)
Share Certificates (%)
Idaho CUs carry a notably mortgage-heavy and certificate-heavy balance sheet. First mortgage concentration rose to 27.27% in 2026-Q1, up 0.76 pp year-over-year from 26.51% in 2025-Q1, and exceeds the national 22.15% by over 5 pp. Share certificates stand at 27.19%, up 0.55 pp year-over-year from 26.64%, and far exceed the national 19.80%. Indirect auto concentration declined to 11.75% from 11.91% in 2025-Q4 (-0.16 pp QoQ) and from 12.48% in 2025-Q1 (-0.73 pp YoY), yet still exceeds the national 7.73% by 4 pp, reflecting Idaho's historically auto-intensive lending culture.
Strategic Implications
- • Decelerating member growth — from 6.77% YoY in 2025-Q1 to 1.08% in 2026-Q1 — signals Idaho CUs must shift from passive expansion to active retention and deepening of existing relationships to sustain revenue.
- • With ROA declining 9 bps quarter-over-quarter and NIM trailing the national average by 5 bps, Idaho CUs should scrutinize funding costs tied to their above-national certificate concentration of 27.19% before further rate concessions erode margins.
- • Loan growth of 3.63% vastly outpacing the national 0.31% is a competitive strength, but the 0.17 pp YoY rise in delinquency to 0.87% warrants tighter underwriting standards, particularly in indirect auto, where concentration remains elevated at 11.75%.
- • Net worth at 11.55% — 2.07 pp below the national 13.61% — limits strategic flexibility; accelerating capital retention should be a priority, especially as balance-sheet growth continues to outpace the industry.
- • The combination of rising first mortgage concentration (27.27%, up 0.76 pp YoY) and a higher-rate-sensitive certificate portfolio creates duration and repricing risk that Idaho CUs should stress-test against a prolonged elevated-rate environment.
