12-Month Treasury Average (MTA)
The Monthly Treasury Average, also known as 12-Month Moving Average Treasury index (MAT) is a relatively new ARM index. This index is the 12 month average of the monthly average yields of U.S. Treasury securities adjusted to a constant maturity of one year. It is calculated* by averaging the previous 12 monthly values of the 1-Year CMT. Because this index is an annual average, it is more steady than the 1-Year CMT index. The MTA and CODI indexes generally fluctuates slightly more than the 11th District COFI, although its movements track each other very closely, as illustrated on our historical graph. |
