Jane Fraser

Since she took the reins of ­Citi’s $11.5 billion Latin America division in 2015, Fraser has faced a number of challenges, mostly coming from economic woes in that part of the world. Under pressure, Citi said in February that it would sell off its consumer banking businesses in Brazil, Argentina, and Colombia. Now ­Fraser—who also gained control of Citi's Mexico operations when she took the job—is focusing on cutting expenses and streamlining businesses. In her first year in charge, both revenues and profits showed improvement.
