2016 may be the year when bank regulators focus more of their attention to anti-money laundering regulations, cybersecurity, and consumer financial technology. The Consumer Financial Protection Bureau also is expected to be busy shaping rules on payday lenders, prepaid cards, and consumer arbitration clauses.

The bureau also has proposals on its agenda that could potentially affect the payday-lending and debt-collection markets, dramatically reduce the impact of mandatory arbitration clauses, and its rules for prepaid cards could even address bitcoin and other virtual currencies.

The bureau in early 2015 released an outline of a proposal that would require changes in the payday-lending market and its practices deemed by consumer advocates to disproportionately harm low-income consumers. Their proposed rules would seek an end to “debt traps” by instituting a number of requirements including that would greatly change the status quo on how those companies operate. The outline of the new requirements was sent to a small-business review panel, and it is expected to issue a formal proposal in February and complete a final rule later this year.

From there the CFPB can expect a protracted fight, said Ballard Spahr LLP partner Alan Kaplinsky.

“There will probably be a general challenge that the rule isn’t supported by any of the empirical data that [the CFPB] generated,” Kaplinsky said. “They did studies, but they were incomplete according to many people.”

A similar battle is likely to ensue as the CFPB moves forward with rules limiting mandatory arbitration clauses in consumer credit contracts, like credit cards. When the rule becomes final, likely by the end of 2016 or early 2017, Mr. Kaplinsky, considered the father of consumer arbitration clauses, said he expects there will be an industry lawsuit.

 “The study that they’ve done does not support a rule banning class action waivers,” Kaplinsky said.
