Iowa's 66 credit unions entered 2026-Q1 with a split story: robust financials masking a deepening membership problem. ROA held steady at 0.88% quarter-over-quarter and rose 8 bps year-over-year, sitting 20 bps above the national 0.67%. Asset growth accelerated to 3.18%, outpacing the national 2.64%. Yet member growth turned sharply negative at -0.95% in 2026-Q1, down 2.78 pp from 1.83% a year ago — now 30 bps worse than the national rate. Sustained profitability without membership expansion raises a structural question: Iowa CUs are deepening wallet share with existing members, but the pipeline of new members is contracting.

Member Growth (YoY %)
Member engagement deteriorated meaningfully in 2026-Q1. Member growth decelerated to -0.95%, worsening from -0.72% in 2025-Q4 (a 0.22 pp QoQ decline) and collapsing from +1.83% in 2025-Q1 — a 2.78 pp year-over-year swing into negative territory. Iowa CUs now trail the national member growth rate of -0.65% by 30 basis points. The shift from positive to negative membership growth within a single year signals a structural engagement challenge that financial strength alone cannot mask. Retaining and attracting members must become a strategic priority.
Profitability
Return on Assets (%)
Net Interest Margin (%)
Iowa CU profitability remained a clear strength in 2026-Q1. ROA was stable at 0.88%, essentially unchanged from 0.88% in 2025-Q4, and increased 8 bps from 0.80% in 2025-Q1 — placing Iowa CUs 20 bps above the national benchmark of 0.67%. NIM was similarly stable quarter-over-quarter at 3.84% (down just 1 bp from 3.85% in 2025-Q4) while expanding 14 bps year-over-year from 3.69% in 2025-Q1, and exceeding the national NIM of 3.70% by 14 bps. Iowa CUs are generating superior returns on both assets and interest income relative to national peers.
Growth
Asset Growth (YoY %)
Member Growth (YoY %)
Balance sheet growth accelerated across most dimensions in 2026-Q1. Asset growth accelerated to 3.18% from 3.10% in 2025-Q4 (up 0.08 pp QoQ) and from 2.81% in 2025-Q1 (up 0.37 pp YoY), comfortably outpacing the national rate of 2.64%. Deposit growth accelerated to 2.77% from 2.70% in 2025-Q4 (up 0.07 pp), beating the national 2.16% by 61 bps. Loan growth, however, decelerated to 1.11% from 1.33% in 2025-Q4 (down 0.22 pp), though it still leads the national rate of 0.31% by a substantial 79 bps. YoY loan growth data is unavailable for direct comparison.
Risk & Credit Quality
Delinquency Rate (%)
Net Worth Ratio (%)
Iowa CUs' risk profile showed modest improvement quarter-over-quarter but remains elevated relative to national peers. Delinquency decreased to 0.91% in 2026-Q1 from 1.00% in 2025-Q4 — a 9 bp improvement — and was essentially stable year-over-year against the 0.91% recorded in 2025-Q1. Nevertheless, the 0.91% rate sits 13 bps above the national benchmark of 0.78%, indicating persistent credit stress. Net worth decreased slightly to 14.57% from 14.67% in 2025-Q4 (down 0.11 pp) but increased 0.49 pp from 14.08% in 2025-Q1, remaining a robust 95 bps above the national 13.61%.
Portfolio Mix
First Mortgage (%)
Indirect Auto (%)
Share Certificates (%)
Iowa CUs' portfolio composition shifted modestly in 2026-Q1. First mortgage concentration increased to 21.77% from 21.53% in 2025-Q4 (up 0.24 pp QoQ) and from 21.10% in 2025-Q1 (up 0.67 pp YoY), though it remains just below the national 22.15%. Indirect auto concentration was stable QoQ at 9.18% (down 0.04 pp from 9.22% in 2025-Q4) but decreased 0.29 pp YoY from 9.47%, remaining above the national 7.73%. Share certificate concentration decreased to 21.81% from 21.99% in 2025-Q4 (down 0.18 pp) but increased 0.21 pp YoY from 21.60%, well above the national 19.80%.
Strategic Implications
- • The -0.95% member growth rate — a 2.78 pp YoY reversal — demands urgent investment in member acquisition channels, particularly digital onboarding and community-based outreach to counter structural attrition.
- • With loan growth decelerating to 1.11% QoQ despite strong asset and deposit growth, Iowa CUs should evaluate whether deposit inflows are being deployed efficiently or accumulating as excess liquidity at a cost to earnings.
- • Delinquency at 0.91% — 13 bps above the national benchmark — warrants proactive portfolio monitoring, particularly in indirect auto (9.18%), where concentration exceeds national levels and credit quality trends may lag collateral values.
- • Iowa CUs' NIM of 3.84% and ROA of 0.88% provide a profitability buffer to invest in growth infrastructure; failing to convert that advantage into membership expansion risks long-term relevance as the member base ages or shrinks.
- • The rising certificate concentration (21.81%, up 0.21 pp YoY, vs. national 19.80%) reflects member preference for rate-sensitive products — Iowa CUs should develop strategies to migrate certificate holders into deeper, stickier relationships before rates shift.
