The Federal Bureau of Investigation (FBI) and the US Department of Justice should get involved in the investigations into the bankruptcy of Silicon Valley Bank, as US Senator Chris Van Hollen suggested today.

“I think they’re going to get involved. I don’t think we should absolutely leave this up to the Federal Reserve,” Van Hollen, a Democrat, told Fox News today.

He said regulators and lawmakers should discuss whether and how to guarantee deposits above $250,000, adding: “We are not going to bail out any bank.”

Earlier today, the Wall Street Journal reported that US Senator Elizabeth Warren, who lobbies for tighter bank regulation, called for an investigation into the failures of Silicon Valley Bank and Signature Bank.

Warren today sent a letter to the inspectors general of the Treasury Department, the Federal Deposit Insurance Corporation (FDIC) and the Federal Reserve (Federal Reserve) urging regulators to review the management and supervision of these banks before they collapse this the month.

The senator says that the preliminary results of the investigation should be announced within 30 days, the newspaper adds.

“Bank managers, who took unnecessary risks or failed to deal with fully foreseeable threats, must be held accountable for these failures. But this mismanagement was allowed to happen because of a series of omissions by lawmakers and regulators,” Warren said in her letter, according to the newspaper report.
