Virgin Money chief executive Jayne-Anne Gadhia has criticised the "alpha maleness" of the banking industry.
Ms Gadhia, who is one of a handful of female chief executives on the London Stock Exchange, told the BBC that "winning at all costs" has become a problem.
"[Ruthlessness in banking] has led to so much loss, so much brokenness in our banking system," she said.
Her comments come after the governor of the Bank of England Mark Carney said the "the age of irresponsibility is over" as he called for longer jail sentences for bankers who break the law.
"Being able to look at a more balanced way of assessing performance is very, very important," she said.
"I don't know that ruthless is right. We want to make everyone better off.
"[Being ruthless] is not illegal but I absolutely believe that good business, which tries to find a win-win for everyone, is going to be the most successful business in the end."
