A report issued by the Federal Reserve early in August should receive far more attention than it has received to date.
According to this FRB study, neither the Community Reinvestment Act (CRA) nor the affordable housing goals of the federal government sponsored enterprises (GSEs) were significant causes of the recent problems in the subprime mortgage market.
Although this report offers "tentative" conclusions, it is remarkable nonetheless to use empirical data to look for a direct link between the applicable regulations and loan performance - and find nearly no link at all!
So, does a link exist between these programs and subsequent mortgage performance?

Superficial Association
Generally speaking, the CRA and the GSEs have been blamed for causing or at least contributing to the subprime crisis. After all, both favor lending to borrowers in lower-income census tracts which accounted for a disproportionate share of the growth in lending during the subprime buildup, as well as a disproportionate share of higher-priced, piggyback, no-income, and high-PITI lending, and elevated mortgage delinquency rates.
But the report concludes that "superficial association may be misleading." This view represents the empirical analysis caution, best stated in the probability dictum: correlation is not causation.
Let's take a closer look at the report.
"With few exceptions, the evidence is scant."
The FRB study is entitled The Subprime Crisis: Is Government Housing Policy to Blame? Written by FRB Senior Economists Robert B. Avery and Kenneth P. Brevoort, the paper, described as "tentative," notes the existence of studies with contrary findings, but says that these studies were based on "associations between aggregated national trends" rather than empirical data.

The paper concludes that "with few exceptions, the evidence is scant" that the CRA or even the affordable housing initiatives of the GSEs actually caused the subprime market implosion.
Housing Policy and Regulations
The study was untaken to examine a growing body of literature suggesting that housing policy, embodied by the CRA and the affordable housing initiatives of the GSEs, may have caused the subprime crisis. But, according to the authors, the conclusions drawn in this literature, for the most part, have been based on associations between aggregated national trends.
The study found that there is:
"...little evidence that either the CRA or the GSE goals played a significant role in the subprime crisis."
Indeed, the quantitative tests conducted actually indicate that areas disproportionately served by lenders covered by the CRA experienced lower delinquency rates and less risky lending.
And so-called "threshold tests" show no evidence that either program had a significantly negative effect on outcomes.
