How long does it take to transfer money from bank of America to HSBC bank?

On average, it takes 3 to 5 days to effect an electronic money transfer from institution to institution. The exception would be if you just deposited a paper check in one bank and you want to transfer the funds to another bank--that could take 10 days or longer if your institution decides that it wants to wait until the check clears. I would advise you to check with your local bank to see what their check cashing/clearing policies are.
