Federal Reserve says it will conduct review of Silicon Valley Bank failure

What they're saying: “We need to have humility, and conduct a careful and thorough review of how we supervised and regulated this firm, and what we should learn from this experience,” said Barr.

• “The events surrounding Silicon Valley Bank demand a thorough, transparent, and swift review by the Federal Reserve,” chair Jerome Powell said in a statement.

The backstory: The Fed moved to loosen certain regulations for mid-sized banks in 2019, which then-Fed governor Lael Brainard (now a top economic official at the White House) warned at the time could pose substantial risks.

• Those moves are top-of-mind for some Democratic lawmakers who are pinning the blame of recent bank collapses in part on the regulatory rollbacks.

• That includes Massachusetts Senator Elizabeth Warren, who said in a New York Times op-ed that Silicon Valley Bank and failed Signature Bank would have been "subject to stronger liquidity and capital requirements to withstand financial shocks."

Between the lines: Silicon Valley Bank was supervised by the Federal Reserve Bank of San Francisco.

• The bank's CEO was a member of the San Francisco Fed's board of directors until Friday, when the bank was closed by regulators, Reuters reported.
