Christopher Whalen, managing director of Institutional Risk Analytics, a research firm, predicts that approximately 110 banks with $850 billion in assets could close by next July. That’s out of 8,400 federally insured institutions, he said, which together hold $13 trillion in assets.

Individual customers are starting to get nervous about the financial health of their banks for the first time in generations, he said. Whalen’s firm analyzes the safety and soundness of banks for business clients, but began receiving inquiries from individuals in the past two months for the first time, he said.

“If we don’t get ahead of this, we are going to face a run on the retail banks by election day,” he said.
