In yet another aggressive deposit-pricing move, Citibank raised its e-Savings rate to 5%, the first major high-yield player to surpass the magic 5% mark on a savings account with a low minimum balance. IndyMac (5%, $25k min) and Countrywide (5.25%, $50k min) hit 5% before Citi, but have higher minimums.

Keep in mind, Citi's account requires a checking account, a significant part of the strategy that has attracted more than $2 billion in new money in the past three months (NB June 1).
