<prompt> Human: Ive got an emergency fund of 10,000 which should cover about 6 months expenses or more. Its main use would be to support myself while Im jobless but I can also see it being used for a car repair or something. Should I invest half of it in bonds? My thinking is if I know Im jobless, I can survive on the first 5k and have ample time to sell the bonds if needed. Whats wrong with my idea?  <response>: I personally keep my emergency fund in cash in a bank because the times when I am likely to need my emergency fund is also the time when the economy can be uncertain. Cash is more certain than other instruments.
