What credit crisis? Citibank is now offering 0% APR interest on balance transfers for 18 months on its Citi Platinum Select MasterCard. Not only is it longer, but notice they are not allowed to say “up to” anymore with new credit card laws. If you get approved – this card requires good to excellent credit – then you’ll get the 18 months. No annual fee. If you have higher interest debt elsewhere, this is a long and flexible offer.
As an opportunity to arbitrage some profit by borrowing at the low rate and investing it elsewhere, it would probably be unlikely even you really tried with a bank CD, and maybe a little better chance with one of those 4% rewards checking accounts.
