1 Year T-Bill

1 Year T-Bill (TCM) – 1 Year Treasury TCM Index - TCM stands for Treasury Constant Maturity. This index is alternatively sometimes expressed as the 1 Year Treasury CMT or Constant Maturity Treasury. It is an index that is calculated by the US Treasury that adjusts all yields on actively traded Treasury securities to a constant maturity of 1 year. This Index is often used to set the rate for adjustable rate loans. This index adjusts more quickly than the 11th District COF and 6 month LIBOR to current market conditions.

6 Month LIBOR

6 Month LIBOR - LIBOR stands for London Interbank Offered Rate. The 6 month LIBOR rate is the average interest rate that banks are willing to loan money to each other for 6 months in the London wholesale money market.
