The Federal Deposit Insurance Corporation (FDIC) has hired BlackRock’s Financial Market Advisory to oversee the liquidation of approximately $114 billion in securities it inherited from former Signature Bank and Silicon Valley Bank.

The portfolios are worth approximately $27 billion for Signature Bank and $87 billion for Silicon Valley Bank, which were retained in receivership after the collapse of the two banks last month.

The securities are primarily comprised of agency mortgage-backed securities, collateralized mortgage obligations and commercial mortgage-backed securities, the FDIC said.

The regulator recently hired real estate advisory firm Newmark Group to assist in the sale of its $60 billion loan portfolio it holds following the collapse of Signature Bank. This portfolio is comprised primarily of commercial real estate loans, commercial loans and a smaller pool of single-family residential loans.

Silicon Valley Bank was the 16th largest federally insured bank when it was closed by regulators last month, which shuttered after its attempts to raise capital failed. The bank’s failure was one of the largest since 2008. The Federal Reserve has since launched a review of the oversight and regulation of the bank and it will be released on May 1.
