The action by the Fed’s Board of Governors, which requires a four-month comment period before becoming final, came as Congress is weighing an Obama administration proposal to strip the central bank of some of its regulatory authority over consumer credit products such as mortgages and credit cards. The administration favors giving those powers to a new Consumer Financial Protection Agency, which would have the sole mandate of protecting consumers from abusive practices such as the weakened lending standards that triggered a collapse of the housing sector. This crisis in mortgage lending quickly morphed into a global financial crisis.

Last week’s Fed vote also came hours after the National Association of Realtors reported that sales of existing homes rose 3.6% in June, the third consecutive month of increasing sales. All regions of the country posted growth, and the percentage of distress sales fell to 31% from 33% in May.

“This report provides further evidence that activity in the housing market is stabilizing and that price declines are slowing,” the New York forecasting firm RDQ Economics said in a note to investors. “The increase in home sales over the last three months was the fastest since May 2004 (in percentage terms) and the NAR reports that the share of distressed sales is declining. This report, along with recent data on housing starts, building permits suggests that we may have seen the bottom in home sales and housing construction.”
