Bankers know that. That's kind of the first or second lesson they'd teach you at a basic financial course. Everything is priced in terms of interest rate and time. They have been trading these things for decades.
Here is an article I wrote in 2020 that explores that volatility, though from another angle: https://omarabid.com/zero-rates-world
Another thing that I find funny is that everyone has "hindsight" now. Everyone is surprised how these banks are surprised that interest rates went up!
Here is a quote from that article in 2020:
> Maybe, but it's also possible that these high prices are here to stay.
I honestly was thinking we will stay in this zero-rate regime for the next decade or more. I suspect the people at SVB thought in a similar fashion and plan accordingly. The responsibility of the blow up is fully on them, however.

Wrong. This is corruption. Janet is picking winners and losers. Some people are losing their deposits and some are not. You are systemic if you had dinner with Janet yesterday.
