Just a month after declining to the lowest level on record, the 11th District Cost of Funds Index took a turn for the worse.

As of November of this year, COFI, an index for some legacy adjustable-rate mortgages, was calculated at 0.603 percent.

The index increased from a month earlier, when it stood at 0.598 percent — the lowest level on record based on data back to 1981.
