there is for checking. The reserve requirement is the amount of money the bank must keep on hand. Some banks put all money in savings accounts to avoid reserve requirements and transferred enough money daily to meet the checking account needs.

The feds caught on and decided that if the savings account is used like a checking account, then the bank would need to have a reserve for it. BUT, how does the fed determine if the savings account is acting like a checking? The feds had to draw the line somewhere, and decided that if a person withdraws money remotely more than six time it is actually like a checking account.

Those six off-site withdraws can be anything not done in the bank itself: online transfers from savings, phone transfers, auto debit payments, etc.

The savings "in-person" withdraws are unlimited: ATM withdraws, transfers done in the bank, teller withdraws, etc.

As mentioned above, Zions Bank will convert the savings account to a checking account and start holding reserves on the account. It is more costly for Zions to hold a reserve. It would be much cheaper for Zions to ignore the withdraws and not hold reserves on the account, but over six transactions makes the account look like a checking account. If Zions ignores the withdraws they will be fined heavily.
