A heavy load of pricey deposits might be a good thing in this interest rate environment.
Funding costs fell hard and fast at the nation's bank giants as the Federal Reserve slashed short-term rates to next to nothing in late 2008, while
Recently, the decline at smaller banks has outpaced as large institutions appear to have approached a floor through which they can drop no further.
But even among big banks, major differences in sensitivity to market rates are apparent in relative holdings of time deposits.
Among a group of 26 bank holding companies with more than $40 billion of assets, the average cost of funds at the eight institutions with the highest proportion of time deposits to assets at June 30 fell 78 basis points from the third quarter of 2009, to 1.37% in the second quarter, nearly catching up with the average at the eight with the lowest proportion, according to data from Financial Information Systems (see charts).
Both groups have taken advantage of loose monetary conditions to rotate out of time deposits, but banks that have traditionally relied heavily on term funding have had more room to maneuver as low rates have set in for the foreseeable future.

Now, banks with big CD portfolios could be in line for another dollop of disproportionate funding relief despite an otherwise
