The 5.56% APY is specified in the promotion page, but it appears this will go down each day since the period during which the CD earns 7% is reduced. Based on my calculation, if the CD is opened tomorrow, the average rate for the 16 months will be about 5.34%. Assuming daily compounding, this would translate to about 5.49% APY.
