Big banks have been committed to working out their mobile strategies over the past two years and are now unveiling the dramatic results they’ve achieved. According to AlixPartners, big banks controlled 67 percent of the primary banking relationships by the second quarter of 2014, while credit unions had 14 percent. Mid-size banks controlled 11 percent, community banks 4 percent and all others at 4 percent. Plus, 78 percent of people who switched accounts went to a big bank, while only 8 percent went to a credit union and the remaining 14 percent to a community bank, mid-size bank or other. It’s an even bigger gap with young people — 82 percent of these switchers went to a big bank, while only 7 percent switched to a credit union, and 11 percent to a community bank, mid-size bank or other. The study also shows that in 2014, 65 percent of the people who switched accounts said that mobile played a role in their decision to switch.
