GRONGHUI, April 27 | According to the Wall Street Journal, US regulators will take over the troubled Republic First Bancorp and are close to reaching an agreement to sell it to another bank. This is the fourth high-profile bank in the US to go out of business since last spring. The buyer's identity is not yet known, and the deal is still likely to break down. Republic First Bancorp faces some of the same problems as the three US regional banks that went out of business last year: as interest rates rise, there are book losses on bonds and a high percentage of uninsured deposits are likely to flee rapidly.
