Bank Failures, Rate Risk, and Crypto’s Role in the 2023 Crisis

Summary

This 2023 commentary argues that crypto activity alone does not explain the U.S. bank failures and stress then unfolding. It points instead to rapid interest-rate increases after a low-rate period, unrealized losses on fixed-income holdings, concentrated depositor bases, and mismatches between asset duration and funding needs. When depositors seek higher yields or withdraw funds, banks may have to sell discounted securities at losses, further weakening balance sheets. The note distinguishes Silvergate’s crypto-linked deposit base from SVB’s venture concentration and reports that Silvergate depositors did not lose funds at that bank.

The author also describes consequences for crypto firms as banks reduce services, including slower transfers and fewer account options for smaller businesses. Bitcoin is framed as an alternative to dependence on banks and monetary policy, while the regulatory discussion contrasts the U.S. environment with developing frameworks in the U.K. and Europe. This is an opinion piece written during a rapidly evolving crisis; it acknowledges uncertainty about Signature Bank’s seizure and presents a particular interpretation of events rather than a complete independent examination of bank failures.

Key ideas

• Rising rates can reduce the market value of fixed-rate securities and make bank funding more expensive.
• Large depositor withdrawals can force banks to realize losses on securities sold to raise cash.
• The commentary distinguishes crypto-linked deposits at Silvergate from venture-sector concentration at SVB.
• The loss of crypto-focused banking services may constrain transfers and account access for crypto businesses.
• The note’s account of the crisis is contemporaneous commentary, and it explicitly leaves Signature Bank’s circumstances uncertain.
