>SVB put themselves in a somewhat bad situation by heavily concentrating the high levels of deposits in 2019-2021 in long-term treasury bonds (which would not have been permitted had not the previous administration not rolled back Dodd-Frank regulations, in no small part due to the lobbying of SVB's CEO).

And they put even more into 30-year mortgage backed securities. Bonds are normally purchased across a mix of maturities by banks. It's strange how everyone is absolving them for the mistake of holding almost no 1-2 year bonds and instead blaming VCs for pulling out.

To be explicitly clear: it's the responsibility of the bank to maintain their own liquidity (just like the borrower needs to do the same with their loan repayments), and putting $100B (33%+) of assets into 10-30Y securities was highly irresponsible and poor risk management.
