best etf for cash?

[economicsjunkie]

The short answer: strictly speaking "no," because the only orthodox cash vehicle is T-bills or a T-bill-only money market fund; but many forum members seem comfortable with FDIC insured accounts because, barring a widespread bank run, they are very nearly as safe.

Ah ok got it, thanks.

I own BIL as my cash portion.  It is all in a tax advantaged IRA account, so in reality is not liquid.  My question is if I am using BIL as my CASH portion and my emergency fund, would it be better to have this in a taxable account for liquidity in case of an emergency or just keep it where it is?

If you're planning to use your PP cash as your emergency fund to avoid having to have a separate cash emergency fund--and you should--then the cash should be accessible.
