Below are different types of interest rates for your information:

• Prime rate: The rate offered to a bank's best customers.
• Treasury bill rates: Treasury bills are short-term debt instruments used by the U.S. Government to finance their debt. Commonly called T-bills they come in denominations of 3 months, 6 months and 1 year. Each treasury bill has a corresponding interest rate (i.e. 3-month T-bill rate, 1-year T-bill rate).
• Treasury Notes: Intermediate-term debt instruments used by the U.S. Government to finance their debt. They come in denominations of 2 years, 5 years and 10 years.
• Treasury Bonds: Long-debt instruments used by the U.S. Government to finance its debt. Treasury bonds come in 30-year denominations.
• Federal Funds Rate: Rates banks charge each other for overnight loans.

• 11th District Cost of Funds: Rate determined by averaging a composite of other rates.
• Fannie Mae-Backed Security rates: Fannie Mae pools large quantities of mortgages, creates securities with them, and sells them as Fannie Mae-backed securities. The rates on these securities influence mortgage rates very strongly.
• Ginnie Mae-Backed Security rates: Ginnie Mae pools large quantities of mortgages, secures them and sells them as Ginnie Mae-backed securities. The rates on these securities influence mortgage rates on FHA and VA loans.

Interest-rate movements are based on the simple concept of supply and demand. If the demand for credit (loans) increases, so do interest rates. This is because there are more buyers, so sellers can command a better price, i.e. higher rates. If the demand for credit reduces, then so do interest rates. This is because there are more sellers than buyers, so buyers can command a lower better price, i.e. lower rates. When the economy is expanding there is a higher demand for credit, so rates move higher, whereas when the economy is slowing the demand for credit decreases and so do interest rates.
