Look at Mint. My bank could offer what Mint does, since Mint is pulling in info from my bank– but they dont. A lot of what Mint is doing seems to be making the information easy to understand. Their UI is beautiful and their UX is intuitive. For me its hard to even understand why certain design decisions were made by my bank.
Beyond that, I would say to invest in mobile experiences. A lot of my interaction with my bank happens on the go as well. And while my banks iphone app is a better experience than the website, it is a little bit crippled.
You should checkout companies like Venmo and Square, who are really innovating in the area of mobile payments.
