Different banks use different rates to attract their customers. Usually, smaller and unwell-know banks have higher rates; oppositely, the bigger and well-know banks have a little bit lower rates. As most investors believe that most well-know and big banks are rarely bankrupt. They believe these banks are too big to be failed. Therefore, investing in the big and well-know banks’ negotiable CD has less risks than investing in those small and unwell-know banks’ negotiable CD. Although small and unwell-know banks have a higher CD rates, investor should know that the higher rate is, the higher risk will be. So, investors should not just automatically choose the highest rate in negotiable CD.
