SVB bankruptcy

I watched a video on youtube, talking about the SVB (Silicon Balley Bank). As you know, this bank is going bad for cash flow and went bankrupt. The main reason is that many depositors tried to withdraw money from the bank because of the rumor that the bank failed to manage cash flow. So the bank needed a lot of cash and try to fetch it from the bond they invested. However, the issue was because of the risen-interest rate, the value of the bond got decreased at the time, which means the bank had a ton of built-in loss. This fact escalated people to get their money back and eventually, the bank went bankrupt. Fortunately, the government will help it and compensate for all money of depositors. It is good that was not going to be Lehman's shock.
