Stability

COFI - Cost of Funds Index

A yield index based upon the cost of funds to savings & loan institutions in the San Francisco Federal Home Loan Bank District.

Tends to lag changes in market interest rates.

COSI - Cost of Savings Index

COSI is a weighted annualized rate of all interest rates in effect for deposit accounts as of the last day of each month for deposits held by World Savings.

Since it is based on the interest rates paid on deposits and those rates tend to be "sticky," this index is very stable.

MTA - 12-Month Treasury Average

A moving average using the previous 12 monthly observations of one-year constant maturity treasury (CMT).

As a moving average going back over the past year, it is more stable than an index base solely on current values.

PRIME - Prime Rate

The interest rate a bank charges its best or "prime" customers. There is a prime rate average listed in the Wall Street Journal that is an average of the largest commercial banks.

The prime rate tends to move in lockstep with changes in the targeted fed funds rate.

LIBOR - London Interbank Offer Rate

It's the rate of interest at which banks offer to lend money to one another in the wholesale money markets in London.

LIBOR is influenced by changes in both the Bank of England's official rate and the targeted fed funds rate.
