SVB was also the preferred bank for various giants in the crypto VC world, including Andreessen Horowitz and Sequoia Capital. Pantera Capital also used SVB as a custodian.
Although it doesn't seem that it was exposure to the crypto industry that did in Silicon Valley Bank (unlike with fellow failed bank Silvergate), the crypto industry has been showing signs of concern that SVB's collapse may impact crypto businesses. In particular, there are fears around the fact that Circle, the company that backs the major USDC stablecoin, kept some of its cash reserves with SVB. Circle disclosed that around $3.3 billion, or around one-third of USDC's $9.88 billion in cash reserves backing USDC, was kept with Silicon Valley Bank.
