Like every other CD term, five year CDs from FDIC insured banks are protected up to FDIC limits (generally $250,000 per account holder per bank). In rising rate environments a five-year CD may not be a good investment. Therefore, the temptation for those looking for yield is to open one, deposit money, and forget about it for five years. The 5-year CD is therefore often the highest offer at your local bank. While banks may offer six-year, seven-year, or even 10-year CDs, the five-year is the longest of the most commonly offered terms.
Five-year CDs are the big kahuna of the CD world.
