As for regulation, she said the final shape of the Washington clampdown on financials is yet to be seen but most certainly will involve an emphasis on less risk.

"They will separate the risk that's on Wall Street from that which is associated with consumer deposits," Whitney said. "It's going to be a tougher environment."
