9/24/2013: About the 3 and 6 month CD rates. A number of astute readers have e-mailed us about rates on the 3 and 6 month certificates of deposit; we've published a rate of 0.00 for a number of weeks now. The data are compiled from the Federal Reserve's H.15 report. Due to historically low interest rates, these CDs are not trading very actively in the secondary market, and so the Fed has stopped reporting these figures. This also means that we will be unable to publish the CODI shortly as well. We apologize for the inconvenience, and we'll begin publishing again when the data becomes available.

There are many possible ARM indexes. Each one has distinct market characteristics and fluctuates differently. The most common indexes are:

  • Constant Maturity Treasury (CMT or TCM )
  • Treasury Bill (T-Bill )
  • 12-Month Treasury Average (MTA or MAT )
  • Certificate of Deposit Index (CODI )
  • 11th District Cost of Funds Index (COFI )
  • Cost of Savings Index (COSI )
  • Wachovia Cost of Savings Index (W-COSI )
  • Wells Fargo Cost of Savings Index (W-COSI )
  • London Inter Bank Offering Rates (LIBOR )
  • Certificates of Deposit (CD ) Indexes
  • Bank Prime Loan (Prime Rate )

CMT. COFI. and LIBOR indexes are the most frequently used. Approximately 80 percent of all the ARMs today are based on one of these indexes.

The other indexes, that can

be used as benchmarks for some types of mortgage loans, are:

If you're deciding which index is better you should understand that there probably is no such thing as a "good" index or a "bad" index. Each index has its advantages and drawbacks, and is used in different situations. Generally, a loan tied to a lagging index (COFI, e.g.) is better when rates are rising. Leading index loans, like those tied to CMT, are best during periods of declining rates.
