The nation's biggest banks have gotten a bad name over the past decade, given their role in the financial crisis combined with the recent sales scandal at Wells Fargo. But there's one big bank that's bucking the trend: JPMorgan Chase (JPM 1.44%).

This week, J.D. Power released its 2017 U.S. retail banking satisfaction survey. The results show that JPMorgan Chase earned a higher customer satisfaction score than the average bank in all 11 of the geographic regions broken out by the survey.

JPMorgan Chase also saw its score improve from the previous year. Its average score among the regions in 2016 was 798. This year it improved to 825, equating to a 3.4% gain. By contrast, the average bank's score last year was 793, while the average this year was 817, translating into a 3% gain.

Consequently, JPMorgan Chase is outperforming a majority of its peers not only on a static basis when it comes to its customer satisfaction score this year, but also on a dynamic basis, as it improved at a faster pace compared with last year.

"[C]ustomer satisfaction is at the center of everything we do," wrote Chairman and CEO Jamie Dimon in his latest letter to shareholders. "Each business has gained market share -- which is possible only when you are improving customer satisfaction and your products and services relative to the competition."

One can point to a lot of reasons JPMorgan Chase is the most dominant force in banking today, but to Dimon's point, customer satisfaction certainly seems to be one of them.
