As a definitional matter, deposits and annuities can only be issued by, respectively, authorised deposit-taking institutions and life insurance companies.
Yet the suspicion that authorised deposit-taking institutions wilfully profit on "float" looks set to persist because, for one thing, it is hard to disprove.
For example, money center banks, deposit-taking institutions, and other types of financial institutions may be subject to different (and occasionally overlapping) regulation.
The outlets, which are not deposit-taking institutions but have courted individuals in local communities for personal loans over the years, were also deemed not crucial to its operations here.
Banks and other deposit-taking institutions provide this function by accepting deposits and issuing debt into capital markets, and then lending these funds on to borrowers, typically at longer maturities.
