CIT Bank 6-Month CD: Earn Expired

This is one of the highest rates currently available, however, there may be better options depending on your financial situation. Also, you will have to consider what it is worth setting up accounts at a new bank, which may or may not have good customer service. There are several high yield savings accounts in the low to mid 4% range with no lock up. However, if the rates go down (pretty unlikely for the next months) you would earn the going rate. They also increase if rates increase.

Another thing to consider is that you are taxed both federally and at the state level for interest. If you live in a high tax state and are in the middle class income brackets, you are probably better off buying treasuries or T-bills, which are not subject to income tax at the state level. So in California, assuming a > $66,296 income, you pay 9.3% in state tax and 22% in federal tax. If you buy a T-bill, you would earn 4.5% or so depending on the going rate and term, which is only taxed at the federal level. This is essentially equivalent to the 5% being taxed at the state and federal level. While not FDIC insured, if US treasuries fail, you probably can't rely on FDIC insurance. You can sell a treasury at any time, just at the market rate, which may go up or down.

There are number of things to consider other than rate, so do your homework. This is a very low risk way to earn 5% APY for the next 6 months, but there may be better options depending on the accounts you already have and your financial situation.

OP's description is wrong.
This is what's on the website for this product.

No idea why this is getting down votes, but the 11 month @4.8% is a no-penalty CD, meaning you can withdraw at any time and keep the interest you accrued. Here, you have to hold for the full 6 months, otherwise you lose some of the interest you accrued. In an environment where the interest rates are changing rapidly, that no-penalty + longer duration is very valuable.
