Citibank is following the lead from some of it's competitors and raising some of it's fees.

Starting in December, the minimum balance for mid-level accounts will go up from $6,000 to $15,000
Anyone who doesn't maintain that balance will have to pay $20 a month.

Customers with EZ checking accounts will be charged $15 a month if they don't keep a balance of $6,000.

The bank is also hiking fees on basic banking accounts from $8-$10 a month.

These moves follow similar announcements from Bank of America, Wells Fargo, J.P Morgan Chase, and others.
