The FICO score formula has long been  the choice of most US lenders, but some reports show the decline in  actual loans may be making these scores somewhat flawed, which is quickly  becoming a problem. Earlier today Bloomberg.com posted a great release  about a woman experiencing these flaws, and deconstructed some of the  reasons why. 
“When Sharii Rey, a paralegal in Portland,  Oregon, had her credit limit reduced by JPMorgan Chase & Co. earlier  this month, she said it would hurt her 760 credit score. That’s not  the bank’s problem, she was told. It’s FICO’s.”
 
After Rey’s $42,500 credit line was  cut to $12,000, her debt relative to available funds almost quadrupled.  This so- called utilization rate is a large component of the FICO formula  and a higher ratio can lower a score. Rey, 62, is concerned a new FICO  score will squash her ability to borrow.
Congressman Luis Gutierrez, an Illinois  Democrat, says the FICO formula, the most widely used by U.S. lenders,  has flaws as banks decrease loans to consumers, regardless of individual  risk profiles. At least 30 million Americans had their credit limits  reduced arbitrarily during the second half of 2008, FICO estimates.  In the first quarter, New York-based JPMorgan and Citigroup Inc. and  Bank of America Corp. in Charlotte, North Carolina, slashed $320 billion  from credit lines, according to a report by former Oppenheimer &  Co. analyst Meredith Whitney.
“Reductions to a consumer’s line  of credit based upon the lending institutions’ overall appetite for  risk has little or no bearing on a consumer’s own risk of default,”  said Gutierrez, chairman of the House Subcommittee on Financial Institutions  and Consumer Credit.
An individual’s FICO score is based  on factors that aren’t directly related to JPMorgan’s decision to  lower a credit limit, said Paul Hartwick, a spokesman for the biggest  U.S. bank by market value.
