ARM Index Rates: Treasuries, Libor Rates, Prime Rate and other common ARM Indexes
If you have an Adjustable Rate Mortgage, your ARM is tied to an index which governs changes in your loan's interest rate and, thus, your payments. This page lists historic values of major ARM indexes used by mortgage lenders and servicers. Check the latest values of many of these indexes.
ARM holders can use these ARM indexes with our ARM Check Kit™ to verify the interest rate adjustments on most types of ARMs.
Lenders and servicers can access the latest ARM indexes on a daily basis via e-mail or via our web service.
HSH also offers a wide variety of mortgage statistics.
