Study warns of potential collapse for almost 200 US banks.

A new study has found that 186 banks are at risk of failure due to the Federal Reserve's aggressive interest rate hikes, which have eroded the value of bank assets such as government bonds and mortgage-backed securities. A run on these banks could pose potential risk to even insured depositors as the FDIC's deposit insurance fund starts incurring losses. Silicon Valley Bank's collapse was due to the market value of its bonds going down when interest rates started going up, coinciding with the financial difficulties many of the banks' customers were dealing with, forcing them to withdraw their deposits.
