What bothers me is that the failed Silicon Valley Bank is now often referred to as a "community bank" even though it had total assets of more than $200 billion.
True community banks, as defined e.g. by the FDIC have total assets of $10 billion or less.
Among those, based on 2019 data, 90% had total assets of $1 billion or less: https://www.fdic.gov/resources/community-banking/report/2020/2020-cbi-study-full.pdf#page=90
Banks that small are very rarely, if ever, "too big to fail." A bank the size of SVB may well be.
