It has a lot to do with SI, nothing to do with SIVB (other than crypto trading with Nasdaq). It also has to do with expectations of higher interest rates.
This is a really wild thought in a high inflation environment. Not that I disagree. Equities can lose dollar value on top of the dollar itself losing value. Some portion of it has to be going back to risk-off assets that were not worthwhile in a zero-rate environment.
People have been doing that for a year now. It's not new. It didn't start happening because of SI and SVB.
1. Crypto events such as collapse of an exchange
2. Fed interest rates
3. Nasdaq (more than S&P500 and Dow).
