Fintech companies, Ziemer said, “are generally working to make financial products and services more accessible, more efficient and available at a lower cost,” so fintech “is too broad of a term to state whether or not more regulation is needed.”

In Ziemer's mind, firms “should be regulated based on what they specifically do.” Digital advisory firm Betterment, for instance, is “appropriately regulated like any standard advisory firm.”

Where the interest lies in new regulation for fintech companies, Ziemer argued, is “in areas where there are currently gaps in the regulatory structure, such as cryptocurrency.”

But former Google CIO Merrill, who's now CEO of ZestFinance, believes the fintech space is “woefully short of regulation.” Fintech companies participating on the panel with him, he said, can't “agree about what the core goals are [in the fintech space], which tells us that we have a regulatory framework to get done.”

Added Merrill: “It's been a tough first quarter for Facebook and for some prominent financial services organizations; having a good regulatory framework maybe would have helped.”

While the financial services space has seen “our share” of regulation “for a lot of good reasons,” BofA's Bessant said, her preference is “self-regulation or standards that are set by the technical part of the industry or by businesses” themselves.

“I'm worried less about a public policy role than I am about getting all of the stakeholders together, because I think that the task is monumental and the urgency really has to be there.”

As to AI, Bessant sees its benefit as making financial services firms “faster and cheaper at what we do.” A little-talked-about fact, she noted, is that AI is “incredibly relevant … in stress testing or capital management in risk management — the power to use data predictively and the power to use data at scale is, in fact, a key component of world-class risk management.”
