Bipartisanship has returned to Washington, thanks to the overwhelming desire of Republicans and quite a few Democrats to roll back portions of the Dodd-Frank Act. Ten years after the onset of the financial meltdown and seven years after the law went into effect, the relentless efforts of the banking lobby seem to be paying off.

The legislation, S.2155, is being sold as much needed relief for smaller banks that were supposedly treated unfairly by Dodd-Frank. Some adjustment to the law might make sense for very small banks, but the bill has evolved into something that will benefit larger institutions that still merit close scrutiny.

Using relief for community banks as a stalking horse, proponents of the bill have added provisions that will reduce the degree of supervision that would be exercised on banks with assets up to $250 billion. Those with assets between $50 billion and $100 billion would benefit the most.

The two dozen banks (listed in a Congressional Research Service report) that would be affected by these provisions are hardly mom and pop financial institutions. And while the most harm to the economy was done by the likes of Bank of America, Citigroup, JPMorgan Chase and Wells Fargo, these mid-sized banks have records that are far from spotless.

Take the case of  Credit Suisse, the Swiss bank whose U.S. operation has assets of about $215 billion. During the final days of the Obama Administration it had to pay $5.3 billion to settle a case involving the sale of toxic securities a decade ago. In 2014 it paid $1.8 billion in connection with criminal charges of helping U.S. taxpayers file false returns. In 2009 it paid $268 million to settle criminal allegations relating to economic sanctions. In all, Credit Suisse has more than $9 billion documented in Violation Tracker, ranking it tenth among all corporations.

Or consider Barclays, the British bank whose U.S. operation has assets of about $180 billion. In 2015 it pled guilty to criminal charges of conspiring to manipulate foreign exchange markets and was fined $710 million while also paying $400 million to settle related civil allegations. That same year it had to pay $325 million to settle a case brought by the National Credit Union Administration concerning Barclay’s sale of toxic securities a decade earlier. Its Violation Tracker total is more than $3 billion, putting it in nineteenth place among all corporations.

Other controversial foreign banks whose U.S. subsidiaries would benefit from S.2155 relaxed regulation include Deutsche Bank ($12 billion in Violation Tracker), BNP Paribas ($9 billion) and UBS ($5 billion).

Foreign banks are not the only bad actors on the list.  Atlanta-based SunTrust, with about $200 billion in assets, has racked up more than $1.5 billion in penalties, including one case in which it had to provide $500 million in relief to underwater borrowers to resolve allegations that it engaged in deceptive and illegal mortgage servicing practices.  Among the other items in its rap sheet is a $21 million payment to resolve allegations that it charged higher loan rates to black and Latino borrowers.

The S.2155 beneficiary list includes half a dozen additional domestic banks with $100 million or more in penalties: Ally Financial, American Express, Discover Financial Services, Fifth Third Bancorp, M&T Bank Corporation, and Regions Financial Corporation.

A bank does not have to be gigantic to be problematic. These culprits should not lumped together with community banks in deciding whether to tinker with Dodd-Frank.
