maybe thats what finally overbalanced pirates books ...........

mass deposits so he assumed he had a lot more to work with ........and then mass withdrawls
when the interest rates were slashed ........

even 4.9% would have been loads if if had been 4.9% for day 1

its  only because its coming down from   7 or 7.7%  does it look like such  a drastic drop ........

 a steady 4.9% with no changes and he might have been able to keep it running
