SVB collapse: short-seller conspiracy vs duration mismatch (2023)
Silicon Valley Bank (SVB) collapsed on 10 March 2023 in the second-largest US bank failure in history. Conspiracy claims attributed the failure to coordinated short-selling campaigns or deliberate destabilisation by financial actors. Federal Reserve, FDIC, and congressional investigations attributed the collapse to SVB's concentration of approximately $91 billion in long-duration mortgage-backed securities purchased at near-zero interest rates, which lost market value as rates rose. When SVB announced a $1.8 billion realised loss from selling securities on 9 March, a Twitter-accelerated bank run ensued. Short-seller conspiracy claims are unsupported.
