That is a crazy high requirement. I am planning on moving to Miami and they need evidence that I've had >3 months rent in the account for 3 months. Who keeps that much money in a checking account?
Any way you slice it 6 months living expenses earning no interest is a huge expense. For the average person putting that away at 30 means delaying retirement by around 2 years. Worse you need to keep adding money in to keep up with inflation.
It’s reasonable to keep 6 weeks of living expenses on hand, but the rest doesn’t need to be in cash as long as you can quickly liquidate it.
When you pull a balance report for proving personal or business funds, your bank includes checking, money market, savings, etc., the literal type doesn’t matter as much.
(Also, for replies saying the 6 months worth should only be in a higher return higher risk account — things that can lose significant value — well, ideally, no, that’s what you do with everything beyond your six months cash and cash equivalents reserve, or carefully understand your risk exposure and ensure black swan deviations would still leave you above your reserve.)
Keep as much as you need to give you time to liquidate other things (like stocks or mutual funds). Especially with inflation as high as it is, keeping that much money in a checking account is just boneheaded.
Why would you want that in a checking account rather than an instant access cash saving account though? Savings interest rates suck atm, but might as well get whatever you can on it.
Not sure how they are in the US, but I've gotten 0.01% last year on my cash savings account. It's not worth keeping money there. The time you spend moving it from there to your primary account eats the interest.
You can quite easily get .5% from anything called a High Yield Savings account. They are FDIC insured. You used to be able to get as high as 1.5%, though with fed rates dropped to 0 that has gone away.
But .5% is still 50x higher than .01 (and many multiple times higher after a few years of compounding interest).
If you have a 15k rainy day fund, you're easily throwing out 1k a decade by keeping it in checkings.
