In the aftermath of the 2008 financial crisis, the banking industry sought to address an ethics crisis with surveys, town hall meetings, appointments of overseers and mechanisms for employees to report malfeasance. Now, the high-pressure sales scandal at Wells Fargo & Co provides more evidence that large US banks may have little to show for the effort.
Bank consultants say tens of millions of dollars are spent each year on initiatives to build a culture of integrity, partly at the urging of regulators such as the Federal Reserve Bank of New York and the US Office of the Comptroller of the Currency.
Octavio Marenzi, co-founder of Opimas, a management consultant that focuses on the finance industry, said banks have spent a lot of money researching their culture and updating ethics handbooks - with little impact.
"A lot of what the banks are doing are superficial attempts," said Marenzi. "It's more window-dressing than anything else."
The continuing spate of scandals reinforces doubts about the effectiveness of such efforts. Wells Fargo's debacle - involving the creation of as many as 2 million accounts without customers' permission - is only the latest black eye for bankers.
Other recent lapses have included widespread rigging of benchmark interest rates by traders at several banks; reports that JPMorgan Chase & Co hired children of high-ranking Chinese officials to curry favour; and allegations in a London court that Goldman Sachs Group Inc bankers hired prostitutes for officials at Libya's sovereign wealth fund to win business.
Wells has also previously faced accusations of discriminatory mortgage lending practices from local and federal authorities. Wells, which has denied the accusations, reached a settlement with the US Department of Justice in 2012.
Earlier this month, Wells reached a $185 million settlement with the US Consumer Financial Protection Bureau and the Los Angeles City Attorney over abusive sales tactics involved in the creation of bogus customer accounts. In a statement, Wells Fargo spokesman Mark Folk said the bank takes responsibility for customers receiving products they did not request.
"Wells Fargo's culture is committed to the best interests of our customers, providing them with only the products they want and value," Folk wrote.
Workers have described a pressure-cooker atmosphere where they risked losing their jobs if they did not hit unrealistic sales targets. They say this pressure defined working for Wells Fargo and directly led to widespread fraud in the opening of bogus accounts.
Wells Fargo officials have countered that problems were isolated to a relatively small number of workers.
Lawmakers who questioned Wells Fargo Chief Executive John Stumpf at a heated Senate Banking Committee hearing last week were unmoved by this explanation, particularly in light of the bank's firing of 5,300 workers over what it described as improper sales.
"Is it normal for 1 percent of a business unit to be fired over fraud?" Republican Sen. David Vitter asked.
Democratic Sen. Jeff Merkley later asked a panel of government officials who regulate Wells Fargo or were involved in the settlement why Stumpf attributed the problem to rogue individuals rather than a pervasive culture or structural incentives installed by bank executives.
On Tuesday, independent directors on the bank's board said they would pursue their own investigation and claw back $41 million worth of previously granted stock awards from Chairman and Chief Executive John Stumpf, who would also forego his salary as the directors' probe continued.
In a statement, Lead Independent Director Stephen Sanger said directors would "take all appropriate actions to reinforce the right culture and ensure that lessons are learned, misconduct is addressed, and systems and processes are improved."
