If they were to sell those MBS today to get cash, bank’s equity would be wiped out

Given that the law allows them not to if they're HTM, you get the same result, just with some delay. Their deposits are short term, and will leave the bank if SVB is not providing competitive interest rates. They cannot afford to pay competitive interest rates if they've loaned out the deposits at a lower rate than depositors now expect.
Once depositors realize this, it's a classic bank run scenario. They know that without help, the bank goes bust, and there's no point in taking any significant risk with bank deposits that aren't even paying any interest, so they take them out. As more people withdraw, the chance of a failure increases, and more people withdraw, etc.
> $SIVB's HTM securities had mark-to-market losses as of Q3 of $15.9 b...compared to just $11.5 b of tangible common equity!!
> Luckily, regulators do not force $SIVB to mark HTM securities to market. But the bank would be functionally underwater if it were liquidated today. 5/10

They will hold onto these MBS with their "Diamond Hands" (r) and hope for Fed pivot.
Even if bank will go bankrupt and sold to another buyer - new owner will still have to hold onto these MBS
No, they’ll hold them to maturity and get back their principal.
