THE BURNED OVER DISTRICT

We all know the road to Hell is paved with good intentions, but I do not believe there were ever any involved with this situation.

Mistakes like a bounced check or a small overdraft have effectively blacklisted more than a million low-income Americans from the mainstream financial system for as long as seven years as a result of little-known private databases that are used by the nation’s major banks.

The problem is contributing to the growth of the roughly 10 million households in the United States that lack a banking account, a basic requirement of modern economic life.

Unlike traditional credit reporting databases, which provide portraits of outstanding debt and payment histories, these are records of transgressions in banking products. Institutions like Bank of America, Citibank and Wells Fargo say that tapping into the vast repositories of information helps them weed out risky customers and combat fraud — a mounting threat for banks.

But consumer advocates and state authorities say the use of the databases disproportionately affects lower-income Americans, who tend to live paycheck to paycheck, making them more likely to incur negative marks after relatively minor banking missteps like overdrawing accounts, amassing fees or bouncing checks.

When the databases were created more than 20 years ago, they were intended to help banks guard against serial fraud artists, like those accused of writing bogus checks. Since then, though, the databases have ensnared millions of low-income Americans, according to interviews with financial counselors, consumer lawyers and more than two dozen low-income people in California, Illinois, Florida, New York and Washington.

Banks are always looking for ways to weed out the marginal customers who are more trouble than they are worth and this has every earmark of such a program. And as usual, it has been carried beyond its original mandate.
