It wouldn't even cover your costs. Most bank current accounts are run at a loss for the bank, and just operate as a loss-leader for other products the banks sell. A current account costs in the region of a couple of hundred dollars a year to run (see countries which charge for current account services).

Assuming the bank is making an (adjusted) return of 2% on your money, the account has to have 10k in it even to break even. Very few current accounts do.
