Lessons from Silicon Valley Bank

Summary

• The failure of SVB and Signature Bank is viewed as amplifying preexisting investor wariness rather than signaling widespread bank failures.
• SVB's business was heavily concentrated in venture capital-backed startups in tech and healthcare within Northern California.
• Deposits at SVB tripled from $62 billion in late 2019 to $189 billion in late 2021 due to rapid sector growth.
• High cash inflows with low loan demand led SVB to invest $91 billion in long-dated Treasury bonds and agency mortgage-backed securities between 2020 and 2021.
• These securities represented roughly half of SVB's total assets, compared to one-quarter at an average bank.
• SVB designated these long-dated assets as "hold to maturity" to avoid marking them to market on its balance sheet.
• Federal Reserve interest rate increases caused bond prices to fall, reducing the market value of SVB's holdings by $21 billion.
• Depositor withdrawals forced SVB to sell bonds, reclassifying them as "available for sale" and crystallizing losses.
• 94% of SVB's deposits exceeded the $250,000 FDIC insurance limit, making them uninsured institutional funds.
• SVB's interconnected client base facilitated rapid information exchange via social media, accelerating the bank run.
• Most banks face asset/liability mismatches by borrowing short from depositors while lending long-term.
• Banks operate with high leverage, meaning modest asset price declines can wipe out equity capital.
• Trust is essential for banks because depositors can move funds instantly if safety is questioned.
• Digital communications allow depositors to withdraw funds online, enabling more than one-third of SVB's deposits to leave in a single day.
• SVB management likely made a flawed bet that interest rates would hold steady or fall while purchasing long-dated bonds at low yields.
• The collapse involved a combination of large bond investment scale, long maturities, Fed rate hikes, and rapid depositor exits.
• The 2008 Global Financial Crisis was driven by widespread acceptance of risky residential mortgages, subprime lending, and complex structured securities.
• The current banking issues are limited to specific institutions rather than the systemic mortgage failures seen in 2008.
