I can think of at least one instance from an earlier crisis (the 1980s S&L crisis) in which a community bank - in this case, Harlem Bank - had large government deposits suddenly withdrawn in order to shore up a "Too big to fail" bank, causing the collapse of the small, community-oriented bank. This matters. Government is a major cash depositor in many banks, and so government policy of cash placement affects the health of banks and the kinds of banks they support with their business.
