A Citi Balance Transfer is a transaction that allows you to move an unpaid balance from a non-Citi account to your Citi credit card. Once complete, the balance you transferred becomes a part of your Citi credit card’s monthly revolving balance. In some cases a Citi Balance Transfer allows you to transfer funds directly into your checking account using your credit card’s available credit.
Balance Transfers sometimes have promotional APRs for a set duration on the balances you transfer.
