How do you know when CD rates go up?

Financial websites such as Learn Bonds and Deposit Accounts provide CD rate forecasts and summaries for investors, according to each website. Deposit Accounts provides readers with the current rates on 1-year CDs and under 1-year CDs, and the banks offering the certificates of deposit.

Several factors determine bank CD rates, including the length of time until the CD matures and the current interest rate environment, explains About Money. The interest rate environment includes rates in general and not just rates on CDs. Many times, investors find that credit unions offer higher interest rates on CDs than traditional banks because they are nonprofit organizations.
