Barclays does not require a minimum deposit or minimum balance to open a CD. The bank's shorter-term CDs pay decent yields compared to the national average, but you can still find more competitive yields if you shop around. Barclays' longer-term CDs are less competitive.
An early withdrawal penalty applies if you withdraw your savings from your CD before it matures. According to the bank’s website, the penalty for the bank’s 24-month term or less is 90 days simple interest on the amount withdrawn.
