Jane Fraser has been named the incoming CEO of Citigroup, becoming the first woman to land the chief's job at one of the leading U.S. banks. Among other top Wall Street firms, women occupy senior spots and lead major businesses. None so far have taken the top job. Here are some of the leading female executives at Citi's main rivals.

Marianne Lake, CEO of consumer lending, JPMorgan

Served as finance chief of the biggest U.S. bank before taking up the role of running JPMorgan's vast consumer-lending business. She is seen as a contender to succeed CEO James Dimon when he eventually retires.

Jennifer Piepszak, chief financial officer, JPMorgan

Previously head of the bank's credit-card business, she took over from Ms. Lake as finance chief in 2019. Also seen as a contender for the CEO's spot, she has also run the bank's business-banking unit and was finance chief of its mortgage business.

Beth Hammack, treasurer, Goldman Sachs

Oversees the Wall Street giant's cash positions and watches its back with regulators. Rare for a back-office executive, she has trading-floor cred after years as an interest-rates trader.

Stephanie Cohen, head of strategy, Goldman Sachs

Has put her M&A background to use building Goldman's new Main Street business through takeovers and partnerships.

Susan Huang, co-head of investment banking, Morgan Stanley

The first woman to run a Wall Street investment-banking division, she helps oversee a quarter of Morgan Stanley's revenues.

Shelley O'Connor, CEO of Morgan Stanley Private Bank

A veteran of the firm's wealth-management business -- she started out as a branch employee in San Francisco -- she is now in charge of the firm's regulated bank, which is rolling out new savings and checking products.

Mary Mack, CEO of consumer and small business banking, Wells Fargo

Oversees consumer and small business banking, which houses a third of the bank's employees and includes its sprawling network of branches.

Ellen Patterson, general counsel, Wells Fargo

Was hired earlier this year by the bank's new CEO, Charles Scharf. She came over from TD Bank Group, where she was also general counsel, and previously was a partner at Simpson Thacher & Bartlett LLP.

Catherine Bessant, chief operations and technology officer, Bank of America

Oversees Bank of America's vast technology budget. A veteran of almost four decades who has worked in nearly every corner of the bank.

Anne Finucane, vice chairman, Bank of America

Tasked with rehabilitating the bank's image after the financial crisis, she is a confidante of CEO Brian Moynihan. She focuses on strategy and oversees environmental, social and governance efforts.
