ANN ARBOR, Mich.—Customer satisfaction across U.S. financial services held steady in 2026, but the gap between banks and credit unions widened as banks continued to gain ground in digital and operational performance, according to the newly released ACSI Finance Study 2026.
The American Customer Satisfaction Index found overall bank satisfaction unchanged at a score of 80, while credit unions slipped 1% to 78. That two-point spread marks the seventh consecutive year banks have outperformed credit unions and represents the largest gap since 2022, underscoring a shift in momentum that increasingly favors banks.
The decline for credit unions was modest but notable. The study attributes the 1% drop largely to weaker ratings for website experience and the number and location of ATMs, while most other customer experience measures were stable or slightly improved. By contrast, banks posted gains across nearly every customer experience benchmark, even as their overall score remained flat.
Banks’ improvements were particularly pronounced in physical access and operational measures. Satisfaction with branch locations rebounded 4% to 77, and ATM locations rose 3% to 79. Speed of in-branch transactions increased 2% to 86, and the ease of making account changes climbed 2% to 84.
Those operational gains, combined with a 6% improvement in complaint handling, helped banks extend their lead over credit unions, the study shows.
Traditional CU Strength
Credit unions continue to excel in traditional service strengths. Courtesy and helpfulness of staff rose 2% to 88, the highest-rated metric in the credit union category, and in-branch transaction speed held steady at 87. However, the study makes clear that strong personal service is no longer enough to offset digital and convenience gaps.
In mobile and digital channels, banks now hold a measurable advantage. Banks outperform credit unions in mobile app quality and reliability, website satisfaction, and overall account management processes.
Credit unions also trail in the convenience of branches and ATMs, areas where banks—particularly super regionals—invested heavily this year.
Segment divergence within banking also tells an important story. While overall bank satisfaction was stable at 80, regional and community banks maintained a strong score of 83, continuing to outperform larger institutions. Super regional banks, however, fell 3% to 77, reflecting service challenges and digital transitions at several major players.
Even so, gains in branch and ATM convenience among super regionals helped lift the industry’s overall operational metrics.
The broader study highlights how digital and AI-driven modernization are reshaping performance across financial services. Banks and wealth firms are scaling generative AI tools such as personalization and virtual assistants to improve efficiency and digital engagement.
That investment appears to be translating into higher satisfaction in digital channels, where banks have steadily strengthened their position, the report suggests.
Financial advisors posted the highest score among finance industries at 82, up 1%, marking a fifth consecutive year of improvement, while online investment platforms showed the strongest year-over-year growth, climbing 3% to 79. The digital rebound in online investing further underscores the importance of seamless mobile and web experiences in driving customer perceptions, the data show.
For credit unions, the data are clear: while member-facing service remains a core differentiator, competitive pressure is shifting toward digital execution and convenience. With banks improving complaint resolution, expanding branch and ATM access, and narrowing historic service gaps, credit unions face growing urgency to modernize digital platforms if they hope to reclaim their long-held customer satisfaction edge.
