Complete Description:About 10 million American households do not use any aspect of the banking system. A large body of research provides evidence that limited involvement in the mainstream financial sector is most common among low- and moderate-income (LMI) households. Although their income may be relatively low, these individuals hold assets and regularly conduct financial transactions, frequently with nonbank financial companies. Estimates of nonbank financial company transaction volume as high as $250 billion annually suggest a reasonable business case for insured institutions trying to attract the banking business of low- and moderate-income consumers. A relatively low-risk way for banks to introduce low- and moderate-income households to the banking system is through a particular type of savings account—the Individual Development Account (IDA). This article explains how IDAs operate, discusses banks’ experience with IDAs, and provides resources for bankers who want to know more about these programs.
