A group of 11 banks, including JPMorgan Chase & Co. ($JPM), Citigroup Inc. ($C), Bank of America Corporation ($BAC), Wells Fargo & Company ($WFC), are making $30 billion worth of uninsured deposits to help prop up beleaguered bank First Republic Bank ($FRC). The move was meant to help build confidence in the U.S. banking system following the collapses of Silicon Valley Bank ($SIVB) and Signature Bank ($SBNY).
