Several indexes are used to determine interest rates for adjustable-rate mortgages. The most common are the moving Treasury average (MTA), the London Interbank Offered Rate (LIBOR) and the US Treasury (UST).

A 12 month MTA is an index determined by the monthly average of one-year Treasury bills. LIBOR is the rate of interest at which banks offer to lend money to other banks in the London wholesale money markets. While both of these indices are commonly used as benchmarks for adjustable-rate mortgages, LIBOR rates tend to move in closer concert with global interest rate benchmarks, such as the federal funds rate, making LIBOR a more volatile index than the MTA.

Yields on Treasury securities at constant maturity are determined by the US Treasury (UST) from the daily yield curve. Therefore, a 5-year, 7-year and 10-year UST rate is based on the average yield of a range of Treasury securities, all adjusted to the equivalent of their respective term of maturity.


When shopping for commercial financing, avoid focusing too closely on costs. On a loan of tens of hundreds of thousands of dollars, a difference of $50 or $100 per month will have little impact on your business in the long term.
