The heads of the Office of the Comptroller of the Currency and the Consumer Financial Protection Bureau said Tuesday they are taking a wide-ranging look at the sales practices at large and mid-size banks in the wake of the Wells Fargo scandal.

Comptroller of the Currency Tom Curry said the enormous earnings pressure in the banking industry could mean that scams like the selling of bogus bank and credit-card accounts have infected institutions beyond Wells Fargo.

“If sales targets and incentive compensation schemes are implemented in ways that threaten harm to consumers and lead to violations of the law, then banks and other financial companies will be held accountable,” CFPB Director Richard Cordray said.

He said incentive compensation practices that have harmed consumers have been problems across industries.

“We are going back and check the cultures at the banks. It will take a very big job to change the culture at the big banks,” said the CFPB chief.

He cited the mortgage origination fraud during the lead up to the financial crisis as how serious and ingrained harmful corporate cultures at banks and non-banks can be.

Curry’s and Cordray’s comments came at a Senate Banking Committee hearing on the revelation two weeks ago that Wells was being fined $185 million by their agencies and other regulators for creating 2 million bogus bank and credit-card accounts in part to become the industry leader in cross-selling financial product4s.

Wells Chairman and CEO John Stumpf said the scandal, which led to the firing of 5,300 employees, was not a “massive fraud” and was not large enough to warrant being disclosed as a “material event” on Securities and Exchange Commission filings.

While Stumpf spent nearly four hours at the hearing trying to downplay the importance of the wrongdoing, the senators were clearly more concerned.

Senate Banking Chairman Alabama Republican Richard Shelby said he is worried there are similar practices at other banks, while the lead Democrat Sherrod Brown said he wants to know if there are.

The Ohio Senator accused Wells Fargo of being downright hostile to some of the victims.

Brown said one solution to lessen the motivation of bank employees to make phony sales and take other actions against customer is to raise base pay.

Tennessee Republican Senator Bob Corker told Stumpf that his failure to give back some of the money he earned when the fraud was going on from 2011 to this year amounted to public relations malpractice.

Massachusetts Democrat Elizabeth Warren went further. She told the Wells Fargo chief he should resign and be criminally investigated.

While Stumpf contended the goal of cross-selling was to deepen customer relationships, Senator Warren said the real aim was to pump up Well’s stock.

Warren said Stumpf’s Wells holdings gained $200 million during the fraud while he was promoting cross selling on 12 stock-analyst calls.

Warren used the hearing as an occasion to attack mandatory arbitration clauses in contracts by financial institutions.

She said without forced arbitration, the Wells Fargo scandal would never have gotten out of hand.

Los Angeles City Attorney Michael Feuer, whose office brought the original suit against the bank, said Wells tried to use the secrecy agreements to hide evidence of the scandal.

Senator Brown said the large number of people who were fired at Wells Fargo for not meeting the ill-advised goals that pressured others to commit fraud should be made whole.

“I am morally concerned about this,” the Senator said.
