The Most Powerful Women in Banking are reshaping not only their institutions, but also their industry.

And each is doing so in her own unique way.

Cathy Bessant, the chief operations and technology officer at Bank of America, is at the top of our ranking this year, reflecting the increasing importance of tech in business strategy across all of banking and her leadership on issues that are key to how the industry adapts to the digital revolution.

Notable additions to the ranking include two new female chief executives at top-40 banks. Ellen Alemany, who is a familiar face, but took a hiatus from banking for several years, is back as the chairman and CEO at CIT Group, where she is working on a tricky turnaround. And Nandita Bakhshi is just heading into her second year as the president and CEO at Bank of the West, a unit of the French banking giant BNP Paribas.

Hannah Grove, Teresa Tanner and Beth Johnson are also newcomers to the Most Powerful Women ranking. Grove, the chief marketing officer at State Street, helped ignite a social media furor this past spring with the now famous Fearless Girl statue.

Tanner, Fifth Third Bancorp's chief administrative officer, has overseen a brand relaunch, a cheeky new advertising campaign, and a revamp of employee benefits. But perhaps most interesting is how she spearheaded a unique initiative that aims to keep new moms from leaving the company — which you really should check out.

Johnson is the chief marketing officer and head of consumer strategy for the newly independent Citizens Financial Group, where she is building a database to help facilitate proactive pitches to customers based on their needs.

The ranking also features longtime stalwarts such as Marianne Lake and Sandie O'Connor of JPMorgan Chase, Barbara Desoer and Jane Fraser of Citigroup, and Diane Reyes of HSBC.

Regional banks with women in the ranking include PNC Financial Services Group, U.S. Bancorp, MUFG Union Bank, KeyCorp, Huntington Bancshares and Regions Financial.

Community bankers are well represented too, thanks to Dorothy Savarese of The Cape Cod Five Cents Savings Bank and Patricia Husic of Centric Financial.

Read on to get the full list and find out what all of these impressive women have been up to.
